OXYGEN in water , *ZEOLITE catalysts , *BENZENE compounds , *CATALYST supports , *CATALYTIC cracking - Abstract
Bio-crude oil from biomass has attracted the attention of many researchers due to its potential as a source of environmentally friendly fuel. The pyrolysis process mainly produces pyrolytic oil which cannot be directly used as fuel due to its high water and oxygen contents, high viscosity, low heating value and other poor properties. In this study, a benzene product was synthesized from bio-crude oil which was produced from the pyrolysis of Gayo arabica coffee pulp. The pyrolysis process of coffee pulp was performed in a 30-litre vessel at a temperature of 420°C. The resulting bio-crude oil was then analyzed under the GC-MS to find out the pyrolytic oil composition. A set-up for bio-crude oil conversion was then prepared using vanadium oxide supported on zeolite catalyst. The catalysts were prepared using the wet impregnation method by varying the concentration of NH4VO3 precursors from 0.1 to 0.2 and 0.3 M. Catalyst characterization was performed under TGA, XRD and FT-IR analyses. The catalytic cracking process of bio-crude oil was carried out using the reflux method where 150 ml bio-crude oil was mixed with 50 g catalyst in a three-neck flask and then heated at 350°C for 2 h. The resulting liquid was then filtered and distilled at 80°C to obtain benzene compounds. Based on XRD analysis results it was observed that all curves have a similar pattern for each type of catalyst, suggesting the peak of 2θ = 27° ascertained the existence of V2O5 on zeolite support. The GC-MS chromatograms indicate a significant yield of benzene detected from distilled product where the highest benzene concentration was 10.58%. Overall, V2O5 supported on the zeolite catalyst is technically feasible for the conversion of bio-crude oil into benzene. [ABSTRACT FROM AUTHOR]

COAL reserves , *STEAM power plants , *BIOMASS energy , *ENERGY consumption , *DRINKING water , *BRIQUETS - Abstract
The Indonesian government is encouraging a co-firing system by adding biomass fuel for steam power plants. This strategy is motivated by coal supplies which continue to decrease over the time. This situation is encountered by utilization of biomass energy to produce solid fuels such as briquettes or pellets with energy equivalent to coal. Another main consideration is that the source of biomass should be sustainable without any conflict with food security. One of sources of accessible, sustainable, and non-edible biomass is the king grass plant. This plant can grow in marginal areas with a relatively short growth period. The main challenge in using this biomass lies in its low energy density. Therefore, it is necessary to develop technology to improve the properties of the solid fuel produced from king grass biomass. In the last few decades, torrefaction at low temperatures has been widely used since this technology effectively improves the biomass properties. The main objective of the torrefaction process is to increase the calorific value and reduce the water content. Prior to torrefaction process, the feedstock was washed and soaked with tap water for 20 h to reduce the ash content. During torrefaction process, biomass was heated in a non-oxidative environment at temperatures below 300°C. Resulting biochar was then ground, sieved and mixed with starch binder at 5 wt% and 10 wt%. Briquette characterization were performed under several techniques including bomb calorimetry, proximate, density, dropped-test and relaxation analyses. The results showed that the highest calorific value was 4648 kcal/kg obtained from TKG60m5b sample. Proximate test results showed that the ash content decreased by up to 11% after the washing process. Overall, the washing and torrefaction processes applied to the king grass biomass caused significant improvement in term of caloric value, ash content, friability and density. [ABSTRACT FROM AUTHOR]

Garlic (Allium sativum) is an indispensable ingredient for enriching and diversifying Indonesian cuisine taste. Indonesian people always use garlic for their daily dishes and any traditional foods. Due to its widespread culinary use, its availability in the market become critical. The main challenge to consistently growing this garlic is Fusarium oxysporum f. sp. cepae, which wilts Allium plants. The application of arbuscular mycorrhiza fungi (AMF) + Bacillus amyloliquefaciens B1 on local garlic varieties named Lumbu Hijau could effectively control F. oxysporum through in vitro and in vivo experiments. In the in vitro test, B. amyloliquefaciens B1 successfully suppressed the growth of F. oxysporum up to 53.41%. The consortium application in the greenhouse reduced disease incidence by up to 39.17%, and the efficacy of this biocontrol reached 84%. In addition, this approach also positively influenced plant growth, such as plant height, total wet shoot and root weight, and also tuber weight. As such, it is essential to use this consortium of microorganisms in field research and carry out a comprehensive investigation to identify any possible phenomena that may arise in the rhizosphere after application.

- Abstract
The excessive availability of coffee-cherry processing residues has garnered attention, owing to potential environmental concerns associated with ground disposal. The current investigation aims to disclose the characteristics of two main coffee agroindustry residues, i.e., coffee pulp and parchment, as well as the resulting biochar which is produced without chemicals and low energy involved. The effects of washing raw biomass on biochar’s physical–chemical properties were investigated. The pre-washed samples were prepared through the following steps: washing, soaking for 20 h, draining, rinsing, and drying under sunlight for 3 days. A slow pyrolysis process was performed at 420 °C in a pilot-scale apparatus to produce biochar. The results show that the pre-washing of feedstock reduced the ash content in coffee pulp biochar from 28.23 to 11.93%. The ash content of coffee parchment biochar decreased from 9.68 to 5.66% as a result of the washing treatment of the raw material. Furthermore, coffee pulp biochar experienced a 25.8% reduction in surface area, while 14% of the coffee parchment was lost due to washing treatment of raw feedstocks. The findings presented in this study offer new insights that are crucial for evaluating the feasibility and advancing the development of a large-scale commercial process for managing coffee agro-industry residues.

This study aims to examine the influence of frugality on subjective well-being (SWB) in early adult online shoppers, with religiosity as a moderator variable. The study participants consisted of men and women aged 18-40 years who are online shoppers in Indonesia. The hypothesis test was carried out using the Multiple Linear Regression technique, and the results of this study showed that the results showed that a positive relationship was found between the three variables. The results of the study also showed that religiousosis positively moderated the relationship between the variables (= 0.073, p 0.10). In addition, it was found that the relationship was negatively correlated with the two variables (P 0.05). In conclusion, it is suggested that online shoppers can implement a lifestyle of simplicity by making a list of shopping priorities, comparing prices between platforms, and considering the use value of products before making purchases.

Pyrolysis is a commonly used method to produce main products such as bio-char, bio-oil and syngas. However, the practical use of syngas as a fuel is currently constrained by suboptimal properties and the necessity for specialized storage. This study investigated the impact of using syngas directly as an additional fuel for heating the pyrolysis reactor on process parameters and the properties of the resulting bio-char products. The experiment was conducted using two process variations: (i) pyrolysis utilizing syngas as fuel for co-firing with LPG, and (ii) pyrolysis using only LPG as fuel. The variables observed during the testing included the consumption of LPG fuel, process time, heating rate, pyrolysis product yields, and the properties of the bio-char. Characterization of the bio-char was carried out through proximate analysis, bomb calorimetry, thermogravimetric and FTIR analysis. Based on the experimental results it can be concluded that co-firing is able to save on the use of LPG and reduce process time. In terms of product yield, there was no significant difference when syngas was co-fired with LPG. In terms of the properties of the bio-char product, syngas co-firing pyrolysis helps in reducing the moisture content, increasing the fixed carbon content, and also increasing the calorific value up to 26855 J/g.

This study utilized coffee cherry residues, which is an abundantly available source of biomass in Indonesia. One of the methods to utilize coffee plantation residues effectively is wet torrefaction. This method is well-known as a hydrothermal method, where the biomass conversion process uses liquid as a medium and reactant in the process. The objective of this work was to develop an effective procedure for converting coffee agro-waste into marketable products using hydrothermal technology. The information related to changes in physical and thermal properties were explored in this work. To achieve the research objectives, three main steps were performed, i.e., feedstock preparation, wet torrefaction, and hydrochar characterization. Two types of feedstocks were studied in this work, coffee parchment and coffee pulp. In the wet torrefaction process, each feedstock was treated using two types of solutions, i.e., distilled water and acetic acid, at different concentrations. The reaction was carried out in an autoclave with a pressure of 2 bar (g) and an operating temperature of 130 °C for 2 hours. The properties of the hydrochar products were then analyzed using various methods, including bomb calorimetry, SEM, density, TGA-DTG, and hydrophobicity analyses. Overall, the results indicated that the hydrochar produced under acetic acid solution had better characteristics compared to that treated under distilled water. In terms of fixed carbon content and calorific value, the values increased up to 25.3% and 4,603 kcal/kg, respectively. Enhanced hydrophobicity was only observed in the coffee parchment hydrochar, where the average time required to adsorb water was 146.6 s, which can be categorized as strongly hydrophobic.

Sugarcane leaves are the main residue constitute approximately 14% of the total weight of the remaining sugarcane after harvesting. An effective method for processing sugarcane leaves residues is needed at low cost without causing any environmental problem. This research aims to disclose the effect of sugarcane leaves densification method applied prior to pyrolysis process in a pilot scale reactor. To evaluate the process and its product, the experiments were carried out into two types: (i) pyrolysis of sugarcane leaves without densification at 320 ℃ with a variation of pyrolysis time for 100,120, and 130 minutes and (ii) pyrolysis of densified sugarcane leaves with the variation of pyrolysis temperature 320 ℃ and 420 ℃. The investigated conditions showed that the effect of sugarcane leaves densification prolong the pyrolysis time up to 240 minutes at a pyrolysis temperature of 320 ℃, and increased the yield of biochar and bio-oil products up to 41% and 38%, respectively. However, in term of the physical properties of biochar products, the fixed carbon content decreased by 7% when the sugarcane leaves were compacted. While other parameters found no significant difference in pyrolysis at 320 ℃, the effect of sugarcane leaves densification is very beneficial especially when the pyrolysis was performed at 420 ℃.

Justice Collaborator aims to facilitate evidence and prosecution as well as fully reveal a crime, especially those related to organized crime. However, not everyone who commits a crime as a perpetrator wants to become a justice collaborator for various reasons, including a lack of legal protection. The formulation of the problem is 1. What is the legal protection for justice collaborators in narcotics crimes so far? 2. What is the ideal concept of legal protection for justice collaborators in the criminal justice process, especially narcotics, in the future? This research uses a type of normative research with statutory, comparative and conceptual approaches. The research results show that in Indonesia, only a few perpetrators of narcotics crimes are willing to become justice collaborators, one of the reasons is the lack of legal protection. The ideal concept of legal protection for justice collaborators in the criminal justice process, especially narcotics, in the future is carried out by reconstructing regulations regarding justice collaborators. Reconstruction can be carried out using two alternatives, namely: reconstructing the Witness and Victim Protection Law, or creating separate regulations regarding justice collaborators in the form of a law.

In recent years, the International Working Group led by the Islamic Research and Training Institute has developed guidelines known as the Zakat Core Principles for effective Zakat supervision. While these efforts represent significant progress and are widely adopted in the Islamic world, we argue that the efforts miss a key piece of the cultural and moral normative frameworks by not examining how Muslim public's support could influence the effectiveness of alternative supervision methods. In environments where transparency and disclosure are prioritised, these cultural and moral norms play a crucial role in differentiating between legitimate and illegitimate zakat transactions. However, the International Working Group primarily emphasises financial reporting and institutional development, which often overlook these cultural and moral dimensions essential for effective zakat supervision. This article draws insights from international practices, such as the Islamic Bank of Thailand's zakat account, where funds are managed within Islamic financial institutions under stringent supervision, and the Lembaga Zakat Negeri Kedah's approach to risk management and public accountability. It argues for adopting an integrated approach that incorporates normative and cultural dimensions, aligned with Indonesia's religious and social contexts, for a more comprehensive zakat supervision and fund management strategy. This approach will not only improve the efficiency of zakat distribution but also enhance public trust in zakat institutions, leading to increased zakat collection and a greater positive impact on those in need.

This study contributes to understanding ecological changes in land use following slash-and-burn land clearing. This study aimed to compare the richness and density of plant species and soil fertility in farmland cultivated for one year (1 Y), three years (3 Y), and five years (5 Y) after slash-andburn, with the conditions in the secondary forest (SF) in Berau Regency of East Kalimantan. Understory plant taxon types, numbers, and soil organic matter were measured in each region using a series of nested plots. The size of each observation plot was 20 x 100 m. Data on understory vegetation composition was collected using 1 x 1 m mini plots at 20 sampling points and divided into five blocks, with a 10 m spacing between sampling points on each property. Understory vegetation species and cover percentage, litter cover percentage, open soil percentage, and soil fertility were measured for each observation plot. The results showed that the land cover percentage increased each year during the 5 years transition from secondary forest to farmland. Furthermore, within the 5 years, there was a change in understory species, particularly the presence of grasses and sedges at 3 and 5 years after the land use change. However, the transition from secondary forest to farmland within 5 years did not alter soil organic matter and total nitrogen. [ABSTRACT FROM AUTHOR]

In Second Language Writing class, the use of student-based assessment such as self and peer assessments has been increasingly promoted in addition to the teacher-assessment (Alias, Masek, & Salleh, 2015; Chang, Tseng, & Lou, 2012; Esfandiari & Myford, 2013) to help the students make a good writing product (Andrade, Du, & Mycek, 2010). Nevertheless, the inclusion of the student-based assessment result in determining the students’ final score still becomes a controversial matter since some studies prove that the student-based assessment and teacher assessment are not in agreement and tend to be questionable (Alias et al., 2015; Panadero, Romero, & Strijbos, 2013). Therefore, to bridge the gap, this study aims at investigating the level of consistency among self-assessment, peer assessment, and teacher assessment in a writing course. Through a correlational research design, the current study involved 21 students who took a paragraph writing course and experienced in self and peer assessing. To collect the data, the students were asked to write an expository paragraph that was assessed through self, peer and teacher assessments. After collecting the data, then the data analysis is done by using Spearman Rank Order Correlation to answer whether or not there is consistency among self-assessment, peer assessment, and instructor assessment. The results reveal that the students provided the same score in self, peer and teacher assessment. However, the correlations in both self and peer-assessment, as well as self and teacher assessment, are not considered statistically significant. The significant difference occurs in the correlation between peer and teacher assessment result only. From this finding, it can be recommended to the teacher to include the result of peer assessment in determining the students' final grade.

A web-based referral tool called SIIRMAAYU is available to moms (mothers) and newborns (neonatal) in the Indramayu District. In order to manage health referrals throughout the 2020–2022 COVID-19 pandemic, this application has been used for more than 10 years, from 2013 to the present. This study tries to investigate the elements that affect both intention and conduct. Unified Theory of Acceptance and Use of Technology (UTAUT2)'s Maternal Neonatal Applications Indramayu (SIIRMAAYU) acceptanceModifications have been made to the Unified Theory of Acceptance and Use of Technology (UTAUT2) model for this study. We collected primary data by utilizing WhatsApp to distribute a Google Forms-based survey to a large audience. Users who had used the app for at least a year and lived in Indramayu were considered research participants. They also had to have referred patients who were pregnant or nursing. 418 persons were collected from the sample using the nonprobability purposive sampling technique. The investigation makes use of AMOS software and structural equation modeling (SEM). According to the findings, the UTAUT2 model may be applied to analyze the Behavioral Intention of application usage and can explain how Use Behavior affects that usage. This research concluded that Habits (H) are significantly influenced by the elements of facilitating conditions (FC) and effort expectancies (EE). In the meantime, usage behavioral intentions (BI) are significantly influenced by performance expectations (PE) and habits (H). While having little effect on usage intention is hedonic motivation (HE), pricing values (PV), and social influence (SI). This study demonstrates that in order to assess the adoption of the SIIRMAAYU application, the UTAUT2 model needs to be updated. [ABSTRACT FROM AUTHOR]

Since 2016, Indonesia has employed the SISRUTE, an online health referral tool for recommending patients from one medical center to another. A new feature will be introduced in 2021–2022, implementing the idea of a competency-based referral system for mothers (maternal) and newborns (neonatal). Referral senders can use this tool to locate hospitals that are equipped to treat patients and are willing to accept patients. The goal of this study is to gather and examine preliminary data on the acceptability and viability of using the competency-based features on the SISRUTE application by health professionals who are participating in the referral system. Users of the application for maternal and infant referrals who had been referred by their patients and had been using the features for a year qualified as respondents for this study. Purposive sampling was utilized to choose the sample, along with in-depth interviews, focus group discussions, and data from a questionnaire survey. The 15 user respondents, five focus group discussions, and survey data from 428 samples were all thoroughly interviewed. The analysis method employs a qualitative descriptive phenomenological approach. The analysis's findings indicate that the competency-based referral feature on the SISRUTE application has the necessary qualities to be used as a system to address maternal neonatal referral patient issues and is user-acceptable. The difficulty results from a corresponding requirement for extra training to improve users' understanding and proficiency in using the features. [ABSTRACT FROM AUTHOR]

Stroke is a disease or functional disorder of the brain due to blockage (ischemic stroke) or bleeding (hemorrhagic stroke) which can cause death and disability of the sufferer. The prevalence of stroke in Indonesia is still relatively high. As a result, we need a preventive action through early detection by understanding the risk factors that can affect the incidence of stroke in Indonesian society. This study aims to identify the most important risk factors for stroke patients in Indonesia between the ages of 41 and 60 years. This study drew on secondary data from the Rand Corporation website, specifically the fifth wave of the Indonesian Family Life Survey (IFLS-5) conducted in 2014-2015. Multilevel logistic regression model is used to model one binary response variable with one or more independent variables for data having a hierarchical structure. A multilevel logistic regression analysis is used to explain the relationship between stroke case (yes/no) and variables of age, sex, activity, hypertension, diabetes, and average age per province. The multilevel logistic regression modeling results revealed that age (p<0.0001), light activity (p = 0.01), moderate activity (p = 0.02), hypertension (p<0.0001), and diabetes (p = 0.01) were significantly associated in level 1 and the average age per province (p = 0.02).

BRAND loyalty ,BOYCOTTS ,GENERATION Z ,ARAB-Israeli conflict ,CONSUMERS ,ANTI-Israel boycotts - Abstract
The purpose of this study is to examine the effect of religiosity and customer trust on brand loyalty among Generation Z (Muslim consumers in Indonesia), during a particular timeframe (post-Israeli-Palestinian conflict), thereby adding nuanced insights to consumer behavior research in a globalized context. The study is located in Cirebon, Indonesia, with research subjects namely consumers who buy products from McDonald's and people who follow the issue of boycotting Israeli products from the Palestinian conflict among FEB Management students of Universitas Swadaya Gunung Jati. The results of the fit model test show that religious values and consumer trust significantly impact McDonald's brand loyalty in the Z generation. Consumer trust has a positive and significant effect on Brand loyalty (Z), with the remaining (1 - 0.505) = 0.495 (49.5%), which is influenced by other variables not determined by the model. This research contributes by bridging the gap between religious values, consumer trust, and brand loyalty, in the post-israeli conflict Z generation (Generation Z, Muslims in Indonesia). The study suggests strengthening the involvement of consumers through social media and promotional events, while also considering the importance of religious beliefs in decision-making.

Biodiesel, an alternative to traditional diesel, is essential for the sustainability of long-term energy supplies and often synthesized through a non-alcoholic route called interesterification. The described synthesis method facilitates the modification of oil and fat by exchanging acyl radical groups between triglyceride and alcoholic acid (alcoholysis), fat (acidolysis), or ester (transesterification). Therefore, this research aimed to determine the effect of the reactant ratio between crude palm oil (CPO) and dimethyl carbonate (DMC), along with the use of an eco-enzyme catalyst, on biodiesel characteristics. The CPO:DMC ratio was 1:1.5, 1:2, 1:2.5, and 1:3, while the immobilized eco-enzyme catalyst was 2%, 3%, 4%, 5%, and 6% of CPO mass. The results showed that interesterification with a 1:3 reactant ratio using a 4%wt catalyst was the best procedure, producing biodiesel yield of 73.65%, density of 0.860 g/mL, viscosity of 4.63 mm
2 /s (cSt), flash point of 113 °C, calorific value of 34.454 MJ/kg, and cetane number of 70.6%. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Salt is one of the materials suitable for use in thermal energy storage applications, so it is necessary to calculate the value of the thermal conductivity of the material. So far, the calculations that have been carried out are considered inefficient when using measuring instruments that already exist in the laboratory, for a more practical need, a portable Arduino-based thermal conductivity device was designed with temperature monitoring using a type k thermocouple sensor. This study aims to determine the ability of the designed tool in measuring the thermal conductivity of a material along with temperature monitoring using Arduino, and then getting the thermal conductivity value of the salt sample. This test equipment was equipped with DC-DC step down and multiturn potentiometer to adjust the power on the heater. An Arduino Uno microcontroller was used to read input from the sensors, process and then generate measurement values that were displayed on the computer using PLX-DAQ software. Calibration of the temperature measuring device was carried out by comparing the temperature measurement results of the k-type thermocouple sensor with the MASTECH MS6514 thermometer using the Root Mean Square Error (RMSE) method and the results of the first k-type thermocouple sensor value RMSE 1.23, the second sensor 1.56, the third sensor 1.68, and the fourth sensor. 2.2. Furthermore, in testing the thermal conductivity of local Aceh salt, the results obtained were close to the reference value, where the reference value of salt was 5 W/m°C and the measurement results using the designed tool are 6.98 W/m°C.

This study aims to model the relationship among Human Development Index (HDI), Per capita Non-Food Expenditure (PNFE), Gross Regional Domestic Product (GRDP) per capita, Gini coefficient and financing. The data is based on data come from the provinces in Indonesia since 2015 to 2019 obtained from the Central Statistics Agency. Simple linear regression model and multiple linear regression model are used to model the data. It can be concluded that there is no positive correlation between HDI and the Gini coefficient, meaning that high HDI can be found in provinces with a Gini coefficient and in provinces with a relatively low Gini coefficient. Non-Food Expenditure per capita has a positive partial effect on HDI. GRDP per capita partially positive effect on HDI. Development financing per capita partially affects the HDI. The best model that provides the relationship among HDI, GINI ratio, per capita Non-Food Expenditure, per capita GRDP, financing is a linear and positive relationship between HDI and Per capita Non-Food Expenditure, per capita GRDP and development financing.

People are becoming more aware of environmental difficulties in this time of globalization. Waste is one such problem, as waste is a major source of pollution in the air, soil and water. It is hoped that all individuals and businesses in Indonesia, including consumers, will increase awareness and concern for the environment as an effort to preserve and restore the earth's ecosystem. Emina products are one example of a company that prioritizes sustainability in its systems and products at PT Technology and Innovation. Emina is considered a product that contributes to a positive reputation and values social responsibility. Green marketing includes all efforts and endeavors directed at promoting, packaging, distributing, consuming, and recalling products through environmental awareness or response. Corporate social responsibility is a condition in which businesses must continue to pay attention to the environment in an effort to reduce environmental problems that have occurred or are occurring. To achieve sustainable growth and performance, corporate social responsibility is an initiative that is integrated into the investment strategy and is considered a corporate social obligation. Brand image, alongside environmental concerns and corporate social responsibility will emerge as an important consideration for companies in the coming years. Consequently, brand image is consumers' and customers' perception of a brand, which in turn inspires trust in the brand. This research highlights the importance of green marketing and environmental accountability in general by building a good perception of the organization's brand within the local community. The purpose of this study is to determine the correlation between brand image (Z) and the impact of corporate social responsibility (Y) and green marketing (X). Uncertainty surrounds most Emina product users who make up the population of this study. In the absence of population information, the sample size for a given study will be calculated based on criteria for an unknown population, resulting in a total of 100 respondents. This research will use a purposive sampling method, which involves selecting a sample from the population under study based on certain criteria. Regression analysis and path analysis will be used to analyze the data. Hypothesis testing, validity and reliability tests, normality and multicollinearity tests, path analysis model fit tests, and SPSS and AMOS Softwer analysis tools will be used for data analysis. According to the findings of this study, green marketing influences consumer perceptions of Emina products favorably, thereby contributing to improved environmental stewardship. Emina is perceived as an ethical and socially responsible entity, which positively impacts its reputation. [ABSTRACT FROM AUTHOR]

Creative spaces have become important places that encourage innovation, collaboration, and imagination in various fields. This study investigates the complex dynamics of creative spaces by studying physical, social, and psychological aspects. We do this from the perspective of different disciplines and designs and see how special characteristics and creative processes interact with each other. We investigate the influence of spatial confirmation, atmosphere, and accessibility on individual creativity and productivity in this setting using mixed methods, including qualitative case studies and quantitative analysis. Our results show that design components such as layout flexibility, natural lighting, and aesthetic appeal influence how people think and interact with others. All this forms a broad creative experience. In addition, this research investigates how organizational culture, leaders and community dynamics play a role in building and maintaining creative ecosystems in these places. By explaining the complex relationship between the physical environment and human behaviour our research offers insights for practitioners, policy makers, and educators who want to create better creative spaces for collaboration and innovation. Using the Visualization of Similarities (Vos Viewers) tool, this research uses qualitative and bibliometric techniques. Using Vos Viewers you can search 992 articles by entering keywords such as; creative space; digital space; customer experience; and metaverse reduction. The results of the analysis show scientific mapping and potential for future research regarding creative spaces as a new marketing world. These results can be used as recommendation variables for researchers conducting further research. [ABSTRACT FROM AUTHOR]

The accuracy of air quality detection is a crucial aspect influencing user trust and satisfaction with artificial intelligence (AI) based air quality detection applications. However, only a few studies have tested the effect of the accuracy of AI-based quality detection on users' acceptance and use of these applications. This study aims to fill this gap by addressing the impact of perceived accuracy on behavioral intention and behavior using the AIKU application. This research uses a quantitative approach with the online survey method, distributed in January 2023 - February 2023 to AIKU users. Valid data were 287 respondents from 317 who were received and analyzed using partial least squares structural equation modeling (PLS-SEM). This study uses a modified technology acceptance (TAM) model by adding perceived intelligence as a mediating variable between perceived accuracy and usefulness. The results showed that nine hypotheses were accepted from the 13 hypotheses proposed. The results section of hypothesis testing shows that the effect of perceived AIKU application accuracy on perceived usability and ease of use is insignificant. However, these influences indirectly affect the behavioral intentions and attitudes of users. Even if users do not perceive purity as an essential factor, the user's attitude towards the application is still positive. This study makes a theoretical contribution by developing the TAM model by incorporating variables of perceived accuracy and perceived intelligence relevant to the AI-based context.

The COVID-19 pandemic is a virus that is changing habits in human life worldwide. The COVID-19 outbreaks in Indonesia have forced educational activities such as teaching and learning to be conducted online. Teaching and learning activities using the online method are familiar, but the effectiveness of this method still needs to be investigated to be applied in all educational systems. This study used the predictive modeling of Recurrent Forecasting (RF) derived from Singular Spectrum Analysis (SSA) to know the online learning method's practicality on the student's academic performance. The fundamental notion of the predictive fusion model is to improve the effectiveness of several forms of forecast models in SSA by employing a fusion method of two parameters, a window length (L), and a number of leading components (r). This study used undergraduate students' grade point averages (GPA) from a public university in Indonesia through online classes during the COVID-19 epidemic. The experiments unveiled that a parameter of L = 14 (T/20) yielded the finest prediction using the RF-SSA model with a root mean square error (RMSE) value of 0.20. Such a finding signified the ability of the RF-SSA to project the students' academic performance according to the GPA for the forthcoming semester. Nonetheless, developing the RF-SSA algorithm for greater effectiveness is essential to acquiring more datasets, such as by gathering a bigger group of respondents from several Indonesian universities.

Jenis dan sumber data penelitian ini adalah data kualitatif. Metode pengumpulan data adalah wawancara dan dokumentasi. Alat analisis data yang digunakan adalah deskriptif kualitatif. Berdasarkan hasil penelitian menunjukkan bahwa praktik jual beli beras di desa Ombu-ombu Jaya mengandung unsur ambiguitas dari segi kualitas dan kuantitas barang yang dijadikan sebagai objek jual beli. Selain merugikan petani karena manipulasi timbangan pada saat penimbangan, penimbangan dilakukan dengan cara tidak imbang dan langsung menebak-nebak berapa berat utamanya. Kata Kunci: Perspektif, Ekonomi Islam, Amalan, Jual Beli Beras

This study aims to determine the purchase decision on credit at PT. Finansia Multi Finance Bangkinang which is influenced by service quality and trust partially and simultaneously. The data used in this study are primary data and secondary data, which were obtained using questionnaires, file research, and interviews. The sample used to test the hypothesis is 90 people, namely consumers who use a credit payment system at PT. Finansia Multi Finance Bangkinang using the slovin formula. The data analysis technique used is multiple linear regression analysis with hypothesis testing carried out by the F test and t test at an alpha of five percent. Based on the results of the study it was concluded that the variables of service quality and trust have a significant effect simultaneously and partially on purchasing decisions. The correlation coefficient (R) was obtained for 0.836, meaning that there is a close relationship between the variables of service quality and trust with purchasing decisions. Furthermore, the contribution of service quality and trust variables to purchasing decisions is 77.2% while the remaining 22.8% is influenced by other factors outside the model.

Fly ash waste is a by-product of coal burning at PLTU Nagan Raya, Aceh Province, Indonesia. Since 2017, the coal used is a mixture of 90% Kalimantan coal (sub-bituminous) and 10% local Nagan Raya coal (lignite) which is still young so that the mineral ash content is still high. Silica is among the interesting minerals to be extracted from fly ash, given its wide range of benefits. This paper describes the process of extracting silica from fly ash at the Aceh power plant through the leaching method using a chemical solution and heating for 2 and 4 hours at a temperature of 100°C. The difference in heat treatment aimed to study the changes in properties and obtain the best method in the silica extraction process. The effect of heat treatment on silica characteristics was studied based on X Ray Diffraction (XRD) test for phase identification, Scanning Electron Microscopy (SEM) test for morphological identification, Energy Dispersive X-Ray Spectroscopy (EDS) test for mineralogy element identification, Fourier Transform Infra-Red (FTIR) test for identification of functional groups and surface chemistry, and differential calorimetric analysis/thermogravimetric (DSC/TGA) test for identification of thermal properties. As a result, it was found that fly ash still contains unburned carbon, which significantly affects its color, and has the potential for application as a hydrogen storage material because its pore diameter structure is larger than 0.7 nm. The silica extracted from fly ash is capable of achieving a purity of up to 87% and exhibits excellent thermal stability, especially at temperatures between 120-300 °C; thus, it has the potential to be a catalyst material in the adsorption-desorption reaction of hydrogen by magnesium, although further research is still needed.
