The comparison between breast cancer recognition by electrical impedance tomography implemented with Gaussian relaxation time distribution (EIT-GRTD) and conventional EIT has been conducted to evaluate the optimal frequency for cancer detection fcancer. The EIT-GRTD has two steps, which are 1) the determination of the fcancer and 2) the refinement of breast reconstruction through time-constant enhancement. This paper employs two-dimensional numerical simulations by a finite element method (FEM) software to replicate the process of breast cancer recognition. The simulation is constructed based on two distinct electrical properties, which are conductivity σ and permitivitty ε, inherent to two major breast tissues: adipose tissues, and breast cancer tissues. In this case, the σ and ε of breast cancer σcancer, εcancer are higher than adipose tissues σadipose, εadipose. The simulation results indicate that the most effective frequency for breast cancer detection based on EIT-GRTD is fcancer = 56,234 Hz. Meanwhile, conventional EIT requires more processing to determine the fcancer based on image results or spatial conductivity analysis. Quantitatively, both EIT-GRTD and conventional EIT can clearly show the position of the cancer in layers 1 and 2 for EIT-GRTD and only layer 1 for conventional EIT.

It is not yet true that many countries have used this restorative concept as an alternative cause of settlement. It is dependent on the laws and policies of every country. Indonesia as a civil law and American civil law arbiter would indirectly see the difference in both material and formal applications in criminal justice. However, the rupiah still had a chance to strengthen to Rp 9,100 per dollar, he said. The approach involves the statue approach (statue approach), and using a comparative approach (approach approach). Additionally, the author USES primary and secondary legal material as a guide in outlining problems. The difference between the implementation of active justice in Indonesia and America can be seen from the implementation of restorative justice itself, whereas in America only certain states apply restorative justice, and so far only 45 states apply restorative justice. The implementation of restorative justice between Indonesia and America however different the legal system certainly has similarities and differences.

Dimethyl ether is an organic compound that has the potential to be used as an environmentally friendly refrigerant. In this study, the performance of dimethyl ether refrigerant was tested and compared with other refrigerants having high working pressure, namely R410A, R410B, and R32. The study results show that dimethyl ether has a lower cooling capacity compared to R410A, R410B, and R32, in the order of 37% to 40%. However, the compression work of the cooling system with dimethyl ether is much lower, i.e., in the order of 30.7% to 36.9%. As a result, the coefficient of performance (COP) of the cooling machine with dimethyl ether is 7.4% to 10.6% higher than that of the three high-pressure refrigerants. The COP increases with the increase of evaporating temperature.

In addition to being used as a fuel and propellant, dimethyl ether (RE170) can also be used as an environmentally friendly refrigerant. Apart from having zero ozone depletion potential (ODP), this compound also has a very low global warming potential (GWP), making it safe for the environment. This study aims to compare the performance of refrigeration machines using RE170 and R410, which has long been used as a refrigerant in air conditioning systems. The study was conducted at various evaporation and condensation temperatures. The results showed that RE170 does have a lower cooling capacity, about 41.5% of the cooling capacity of R410A. However, the power required on the system with RE170 is very low, which is only about 35.5% compared to the power required by the system with R410. As a result, the system with RE170 has 16.9% better energy efficiency. Thus, RE170 is not only environmentally friendly but also energy efficient. Another important finding of this study is that RE170 is superior to R410A in terms of energy efficiency at high condensing temperature.

This study investigates the application of a Rotary Drum Filter (RDF) in a community-based aquaponic system, focusing on its impact on water conservation, operational efficiency, and economic viability. The RDF, incorporating a 200 mesh screw made from stainless steel 316 (SS 316) and a casing of polypropylene (PP), is designed for enhanced durability and chemical resistance. Key parameters such as water inlet and outlet diameters, body dimensions, and flow rate were optimized to suit the specific needs of a small to medium-sized aquaponic system. The implementation of the RDF resulted in significant water savings, reducing the need for frequent water replacement while maintaining high water quality. The compact design of the RDF allowed for seamless integration into the existing system without requiring additional space. Moreover, the study highlights the RDF’s ability to minimize labor requirements, making it an ideal solution for community-driven projects with limited resources. The findings underscore the importance of advanced filtration technology in improving the sustainability and efficiency of community-based aquaponics, addressing the research gap in this underexplored area.

This study investigates the integration of advanced rainwater harvesting systems in urban residential buildings, focusing on their effectiveness in meeting Drinking Water Quality Standards (DWQS) and implementing effective mosquito control measures. As global challenges such as water scarcity and climate change intensify, sustainable water management practices have become critical. Rainwater harvesting, a time-tested approach, is increasingly recognized for its potential to reduce reliance on municipal water supplies and enhance the resilience of urban environments. The research addresses significant gaps in the current literature by evaluating a comprehensive system that not only harvests and filters rainwater for potable use but also manages grey water for non-potable applications. Through simulation and laboratory testing, the study assesses the system’s ability to meet DWQS while preventing mosquito breeding, which is vital for public health, particularly in regions prone to vector-borne diseases. The results indicate that the system is highly effective in maintaining water quality and controlling mosquito populations. The water collected consistently met DWQS, and no mosquito larvae were detected in the final storage tanks. These findings highlight the system’s suitability for integration into urban residential designs, supporting both sustainability and public health objectives.

Gaussian filters are widely used in image processing applications, such as edge detection, segmentation, and feature extraction. However, computationally intensive computations can take a long time to process large images. Therefore, a parallel algorithm implementation is necessary to accelerate the process. The authors proposed the use of Orange Pi SBCs for parallel image processing tasks involving a Gaussian filter. This paper outlines the steps for implementing a parallel Gaussian filter on a cluster of SBCs. The performance of the parallel implementation was evaluated in terms of speedup and efficiency, which are essential parameters for measuring the effectiveness of the approach. The parallel implementation speedup is described as the ratio of the time required by the serial implementation to that required by the parallel implementation. The parallel implementation efficiency is described as the speedup ratio of the number of SBCs in a cluster. The results of the performance evaluation show that the parallel implementation of the Gaussian filter on a cluster of Orange Pi SBCs can achieve significant speedup and efficiency compared to the serial implementation. The speedup increases with the number of SBCs used in the cluster. Using four SBCs can result in a speedup of up to 2.1 times faster than serial implementation. The efficiency also increases with the number of SBCs used in the cluster. Using four SBCs could achieve an efficiency of up to 53.4%.

The catching of blue swimming crabs in Betahwalang Village, Demak Regency was carried out using traps. The fishing process requires bait to lure the crab into the trap. In Betahwalang Village there is a crab processing plant which produces quite a lot of waste in the form of crab shells. This research was conducted to find out the difference between crab catches and Bubu fishing gear using petek fish, crab fish and crab carapace waste and to find out the width of the carapace of the caught crab. The method used in this study was experimental fishing, using 30 units of fishing gear. The baits used were ponyfish, bagrid catfish and swimming crab’s shell waste, 10 traps each. The conclusion of this study is that statistical analysis shows the differences in bait on trap fishing gear have no effect on blue swimming crab catches in Betahwalang Village, Demak Regency. This shows that the shell waste can be an alternative bait for catching blue swimming crabs, because the results are not different from those caught using ponyfish or bagrid catfish as baits. The width of the carapace of the blue swimming crab caught is 85 – 122 mm, 73.5% of which are > 100 mm in size which is in accordance with the Regulation of the Minister of Maritime Affairs and Fisheries (PERMEN KP) No. 16 Year 2022.

Like other natural resources, groundwater is also being exploited at an increasing rate, especially for domestic requirements. Groundwater is preferred as a domestic water source because of its continuous availability and relatively good quality. Unfortunately, not all places have sufficient groundwater availability of good quality. The purpose of this study was to analyze the characteristics of the aquifer in the study area and evaluate its groundwater potential for domestic needs. Aquifer characteristics were determined based on geological and geomorphological conditions, while groundwater potential was calculated using a static approach. The results showed that the characteristics of the aquifers in Kediri Regency are various. In the eastern and central parts of the study area, the characteristics of the aquifer can be in the form of unconfined aquifers with high productivity. In the western part, most of them have non-aquifer material, so it is difficult to find groundwater. Groundwater generally fills joints and diaclase formed in andesitic lava with low discharge. Although the conditions of the aquifer are various, in general, the potential for groundwater in Kediri Regency can still support its requirements because the potential for groundwater in Kediri Regency is 71,121,313,394 m3, while domestic requirements is 52,348,490 m3/year.

The aim of this study was to investigate the effects of mobile phone electromagnetic radiation (MP-EMR) on the thyroid glands and hormones in Rattus norvegicus brain in term of thyroid function, reactive oxygen species (ROS), and monocarboxylate transporter 8 (MCT8) concentration. Forty rats were divided into different groups: control (without EMR exposure), EMR1 (120-min/day exposure), EMR2 (150-min), and EMR3 (180-min). The levels of serum thyroid stimulating hormone (TSH), thyroxine (T4), and malondialdehyde (MDA) and brain and MCT8 were measured using enzyme-linked immunosorbent assay. One-way analysis of variance followed by the Duncan test was used to analyze the data. Our data indicated that the levels of serum TSH and T4 in all the EMR groups were lower significant postexposure compared to the control with P < 0.01 (EMR1 and EMR2) and P < 0.001 (EMR3), suggesting hypothyroidism due to MP-EMR exposure. Increased MDA and decreased MCT8 levels were also observed following the intervention; however, the changes in both concentrations were notably significant after being subjected to 150-min and 180-min of exposure. In conclusion, a significant reduction in TSH, T4, and MCT8 levels indicated thyroid dysfunction due to MP-EMR exposure.

The Dolly area, known as a former red-light district in Surabaya City, is closed, as instructed by local government policy in 2014. This transformation negatively impacted the psychological and economic of vulnerable community groups in the surrounding area, especially women. This research is conducted to revisit the impact of Dolly area closure instruction and policy after ten years. The research is done qualitatively in the Former Dolly red-light district, Surabaya City, by obtaining the primary data through focus group discussions (FGD) in 2023. The analysis method used is TNA (thematic network approach), which is processed and visualized using NVIVO 12 pro. Feminist Standpoint Theory (FST) is used as a theoretical framework to ensure that the knowledge produced involves the participation of individuals who experience it directly. The results show the majority of former sex workers' lives, mainly women, rarely experience a decent life of living after 10 years of Former Dolly red-light district closure. There are three main obstacles (theme) causing this, which is: social, economic and administrative. The poor welfare of this community group leads to discrimination and stigmatization of former Dolly sex workers, and they become more psychologically vulnerable, marginalized and rarely considered as strategic development subjects. Apart from that, excessive social problems such as discrimination and stigmatization affect their economic activity. They lost the freedom to enter a legal sector as labour. Instead, they were forced to enter the shadow economy sectors, such as returning as sexual workers illegally.

This study evaluates the implementation of SMP/MTs local content curriculum policies (LCCP) in Jepara Regency. It includes an analysis of Regional Regulation No. 1 of 2018 formulation, evaluation of local government policies regarding SMP/MTs local content curriculum, analysis of policy impact on local content curriculum, and sustainability analysis to the SMA/MA/SMK level. The qualitative evaluation method was employed, focusing on Jepara District Government's policy. Data were sourced from the Department of Youth and Sports (Dispora), DPRD, SMP/MTs, and the furniture industry. Data collection methods included in-depth interviews, document studies, surveys, observations, and questionnaires, validated internally and externally through qualitative data analysis. Findings indicate Jepara Regional Government Policy formulation involved various stakeholders and met community representation and scholarly standards. However, the local government's policy implements Curriculum 2013, integrating carving skills into Arts and Crafts Lessons, contrary to the local regulation mandating carving as a separate subject in SMP/MTs. Non-compliance impacts limited involvement of the younger generation in tradition development, risking the decline of local culture. For sustainability, local regulations are needed for teaching carving content in SMA/MA/SMK, as these graduates contribute to the workforce. This study emphasizes aligning policy with practice to preserve and promote local traditions and skills across educational levels.

This study aims to conduct a statistical evaluation of the correlation between character education and Islamic Religious Education (PAI) learning outcomes among students in Indonesia, addressing the variations in findings from previous research. A meta-correlation analysis was employed, analyzing data from 36 independent studies derived from 24 primary sources published between 2019 and 2023. The data was processed using JASP software (version 0.16.4). The analysis yielded a combined effect size of 0.30 (p < 0.001) based on a random effects model, indicating a small but statistically significant effect. These results suggest that improvements in character education are positively associated with academic achievement in Islamic Religious Education. The findings underscore the importance of integrating character education into the curriculum to enhance students' learning outcomes in PAI.

This study aims to evaluate the effectiveness of neuroeducation implementation in elementary education and develop a teacher training model to enhance understanding and application. A quantitative approach with a survey and quasi-experimental design was employed across seven regions in Indonesia, involving 28 public elementary schools implementing the Kurikulum Merdeka. Data were collected through evaluation questionnaires and structured interviews completed by teachers following neuroeducation training. The results show a significant increase in teachers' understanding and application of neuroeducation principles, with the average understanding score rising from 2.7 before training to 4.5 after training. Structured interviews revealed that while teachers felt more confident in applying neuroeducation, they still required ongoing support. The discussion links these findings to Andragogy, Constructivism, and Lifelong Learning theories, highlighting that experience-based and continuous training effectively enhances teacher competence. The conclusion drawn from this research is that neuroeducation can be effectively implemented in elementary schools with appropriate training support, contributing to the improvement of elementary education quality in Indonesia.

Gampong Pande on the north coast of Banda Aceh city which was destroyed after the 2004 earthquake and tsunami has been reconstructed with the assistance of the Asian Development Bank (ADB) with a comprehensive approach. One of the important steps taken for future disaster mitigation is to develop a village plan. The village plan was prepared with the aim of rebuilding the village and its inhabitants with a “build back better” approach. The community participation approach is carried out while respecting local culture but trying to introduce ecological aspects as part of disaster mitigation as well as economic resources. Village plans are also prepared based on efforts to minimize changes the existing land ownership patterns to avoid social conflicts, so that massive and careful social and land ownership data collection is carried out. To increase safety efforts during the earthquake and tsunami disaster, proper access is made for all land and houses to the ideal evacuation route. In addition to rebuilding houses to standards that are in accordance with the building code, the village plan is also presenting the development of better environmental infrastructure and facilities as part of efforts to rebuild community livelihoods after the disaster. Environmental quality improvement is also carried out by utilizing local coastal plants for ecological disaster as well as for community economic improvement.

An isolated dockyard located in West Papua currently relies on two diesel generators (DGs) with a total capacity of 1,100 kW to fulfil its energy demand. However, these DGs operate at low efficiency, resulting in a high levelized cost of energy (LCOE) of Rp9,064 /kWh and generating 496 metric tons CO2 emissions equivalent per year. On the other hand, the dockyard holds significant solar energy potential. There is opportunity to utilise solar photovoltaic (PV) since its LCOE is also decreasing. This study aims to determine the optimal configuration and sizing of a PV-battery-diesel to minimise LCOE, considering CO2 emissions and a maximum capital expenditure (CAPEX) constraint of Rp 16.4 billion. Four topologies are evaluated: DG, PV-DG, PV-battery, and PV-battery-DG topology. The results highlight the PV-battery-DG topology as the lowest LCOE of Rp3,185 /kWh while adhering to the CAPEX constraint. The PV-battery topology is the most effective in reducing emissions by 100%. Both the PV-battery-DG and PV-battery topologies are less sensitive to fuel price volatility but are more influenced by changes in inflation rates. In contrast, the DG and PV-DG topologies are relatively less responsive to inflation changes but significantly responsive to variations in fuel prices.

The demand for environmentally friendly refrigerants arises to anticipate two global environmental issues: global warming and climate change. The use of environmentally friendly refrigerants is one of the efforts to address these issues. This study aims to investigate the possibility of the use of dimethyl ether (DME) for substituting R134a that has been widely used worldwide. The simulation reveals that both subcool and superheat affect the performance of both refrigerants. The cooling capacity of R134a system increases with the increase of subcool and superheat. Meanwhile, even though the cooling capacity of DME increases with the increase of subcool, it decreases with the increase of superheat. For subcool 0C, DME has a coefficient of performance (COP) 4.8% higher than that of R134a although the cooling capacity is 4.5% lower. When the subcool is set at 8C, the cooling capacity of DME is 6.5% lower than R134a but the COP is 2.6% higher. Another important finding in this study is that the best performance of DME over R134a is obtained at low subcool and low superheat.

The number of illegal mining sites in Indonesia is estimated to be around 2.700, with the number of mining accidents reaching 104 in the period 2013-2021. The number of accidents is high and often causes fatalities. This research focuses on reactivating illegal mining in Pancurendang as a source of livelihood for the local community. We focused on analyzing the causes of the trapping of 8 miners in Pancurendang Mine. It revealed more than 110 mining pits, with 30 active mining pits in the mine. The methodology we used was the Human Factor Analysis Classification System (HFACS) framework to process the data. Data collection was conducted by direct observation at the incident site, interviews with miners and the national rescue agency, as well as a comprehensive literature review. Improvements were proposed in a hierarchical analysis based on the HFACS Framework. The analysis showed that the incident was caused by several factors, such as skill-based error, physical environment, absence of supervisor, organizational physics and societal. The results of this study highlight the need for the development of professional mine organizations, safer working environments and responsibility for safety in small-scale gold mining, and provide valuable insights in the development of geotechnical engineering.

This study aims to determine the contribution of green banking to integrated Sharia Maqasid- based performance and to reveal whether social performance with Islamic Social Reporting (ISR) disclosure strengthens the relation between green banking and integrated Sharia Maqasid-based performance. We evaluated the research model using the PLS algorithm and then carried out hypothesis testing. Then, using the purposive sampling method, 130 data were collected from 26 Sharia Banks, 9 Sharia Banks in Indonesia and 16 Sharia Banks in Malaysia, from 2018 to 2022. We find that Green Banking positively affects Integrated Maqasid Al-Shariah Performance Measures, and ISR hurts Integrated Maqasid Al-Shariah Performance Measures. Furthermore, the disclosure of ISR strengthens the effect of Green Banking on performance based on integrated Sharia Maqasid. However, no bank has a high score and fully meets the requirements for green banking, Islamic Social Reporting, and performance based on integrated Maqasid Sharia. Therefore, Islamic banks in Indonesia and Malaysia need to maximize the expansion of green banking, Islamic Social Reporting, and performance based on integrated Sharia Maqasid

Community and private partnership (CPP) in tree planting initiative is potential to accelerate rehabilitation of degraded lands. Yet, empirical studies to analyse such programs are limited. Here, we analysed a CPP tree planting program in East Java, Indonesia by focusing on ecological aspects, i.e. vegetation cover changes, floristic diversity, above-ground carbon storage, and soil and microclimate conditions. Results showed that there was a striking increase in vegetation cover, yielding a total carbon sequestration of 3,853 tons, or equivalent to the reduction of 14,140 tons of CO2 emissions. On the other hand, co-benefits in term of floristic diversity at a landscape scale was low, and soil and micro-climate conditions were still marginal. This study provided empirical evidence that collaboration between communities and private entities in tree planting program can be effective in rehabilitation of degraded lands. Improvement in land management systems applied in tree planting through the implementation of mixed gardens or complex agroforestry is suggested if aiming for co-benefits in floristic diversity and soil properties. Our study recommends a broader adoption of a similar scheme in rehabilitation of degraded lands across Indonesia.

Pennilaian bencana kekeringan menggunakan metode Standardized Precipitation Index (SPI) dengan input data curah hujan mulai dari tahun 2000 sampai 2019. Sebaran ancaman bencana kekeringan dianalisis secara spasial berbasis sistem informasi geografis. Hasil penelitian menunjukkan bahwa indeks kekeringan (SPI-12) memiliki kesesuaian dengan kondisi kekeringan yang terjadi di lapangan. Kesesuaian indeks kekeringan dianalisis berdasarkan data jumlah pengiriman (dropping) air bersih ke lokasi penelitian. Kekeringan ekstrem terjadi pada bulan September 2018 dengan nilai indeks kekeringan (SPI-12) sebesar -2,33, kondisi ini memiliki kesesuaian dengan kondisi kekeringan di lapangan yang ditunjukkan dari jumlah dropping air. Strategi mitigasi dampak kekeringan dalam penyediaan air bersih diantaranya: membangun embung atau waduk untuk menampung air hujan di Kecamatan Ranuyoso dan Randuagung, sedangkan strategi penyediaan air bersih di Kecamatan : Padang, Klakah, Kedungjajang dan Gucialit dilakukan dengan memanfaatkan potensi air tanah atau sumur bor. The drought that occurred in the northern region of Lumajang regency impacts the reduced availability of clean water. This study aims to assess drought disasters and determine strategies for providing clean water supply in the northern region of Lumajang Regency. Drought assessment using Standardized Precipitation Index (SPI) with precipitation data from 2000 to 2019. The drought outputs were spatially plotted using geographic information systems. The results showed that the drought index (SPI-12) complies with drought conditions that occur in the field. The suitability of the drought index is analyzed based on the number of deliveries (dropping) of clean water to the site or location. Extremely dry occurred in 2018, with the highest index value (SPI-12) of -2.33 in September 2018. This condition has conformity to the drought conditions in the field indicated by the amount of dropping water. Drought mitigation strategies in providing clean water include building retention basins or reservoirs to accommodate rainwater in Ranuyoso and Randuagung subdistricts. Meanwhile, the strategy of providing clean water in Padang, Klakah, Kedungjajang, and Gucialit subdistricts is carried out by utilizing the potential of groundwater or drill wells.

A frequency counter is essential for resonance-based sensors like quartz crystal microbalance. An electronic nose or tongue using a QCM sensor array requires a multichannel frequency counter to detect the frequency shift of the sensors simultaneously. The frequency counter’s resolution, precision, and sampling speed are important factors. Board size, energy consumption, and rapid deployment are also considered in the design. This work shows the development of an independent multichannel frequency counter using a commercial Xilinx Spartan 6 series XC6SLX9 board module and a microcontroller board. Both modules are general-purpose modules; therefore, there is no need for a printed circuit board design, resulting in a quick implementation: the use of FPGA results in a compact size and low energy consumption. The developed counter is designed based on a reciprocal counter utilizing the internal logic block of the FPGA. The FPGA module has a built-in 50 MHz TCXO clock and is the reference clock. The high-resolution timing of the counter is realized by multiplying the 50 MHz clock by 6 to reach 300 MHz. The multiplication utilizes the PLL modules in the FPGA. The high precision and accuracy of the counter are achieved by calibrating the timing clock to a 10 MHz rubidium oscillator. The data communication to the microcontroller is done via the SPI by implementing the SPI protocol in the FPGA. The resource is optimized by utilizing PLL and DSP blocks for the counter. Only 5% registers and 5% LUTs of the FPGA resource are used to build a four-channel frequency counter. The result shows that the counter can measure the frequency of incoming signals with a resolution of 0.033 Hz at 10 MHz with a sampling time of 1 second. The system has been tested to monitor the frequency changes of a QCM sensor array.

This study aimed to acquire preliminary data to evaluate the EIT method for differentiation of artificial solid and cystic tumors in comparison to standard US.

Background: Based on thermal temperatures around the breast, thermography is considered a promising approache providing information about the condition of the breast without any side effects. Objective: Using thermography, breast screening is highly dependent on the process of heat recognition. The angular effects in the process of thermal patterns recognition can increase false detection. The effect can be observed in breasts with growing mammary glands. This study aims to develop a system to identify breast conditions through analysis of temperature and thermal patterns.Material and Methods: In this experimental study, analysis of thermal patterns are performed using the Canny method, specifically detection of anomalies in the breast. Twenty-four Wistar female rats were used as experimental animal models with group 1 (normal), group 2 (induced with DMBA), group 3 (rats with growing mammary gland). At the end of 8 weeks, all rats were sacrificed and histopathology analysis was performed. The body temperature was measured every week using the Infrared Camera type TiS20 brand Fluke camera. Results: Histopathology indicated average temperature of 36.66 °C, 37.77 °C and above 38.87 °C in normal, growing mammary glands, and cancerous breasts, respectively. These results revealed significantly higher heat in breasts with cancerous lesions. In the analysis of thermal pattern recognition for breast, no curve was formed in the normal group, while cancerous and growing mammary glands demonstrated a perfectly closed curve and an imperfect curve pattern, respectively. Conclusion: Breast screening through the analysis of temperature and thermal patterns can distinguish normal, cancerous and breast with growing mammary glands.

Literacy competence becomes a fundamental need for students to support their learning process at school. Likewise, the contribution of functional literacy is very important in living a social life and communicating in the current 4.0 era effectively. This article aimed to describe the form of functional literacy and the obstacles in the implementation of functional literacy program in junior high schools in Yogyakarta. This article used library research and direct observation of the implementation of functional literacy in schools as the research method. The results of the study showed that, first, functional literacy program implemented in schools was still merely accustomed to reading and writing. Schools, in general, have made literacy programs such as reading posts, library visits, work exhibitions, meaningful writing, writing as a response, writing exhibitions, and creative and academic writing. However, the implementation of functional literacy towards the development, learning, and functional needs of students has not been planned and implemented optimally. Second, the constraints on the implementation of functional literacy came from the students and the schools. In addition to the students' lack of motivation, feeling unfocused, tired, and bored also hindered the effectivity of literacy program implementation. The constraints stemming from schools included the lack of budget for literacy programs, the lack of time allocation and new reference sources, and no collaboration between school members in the implementation of literacy programs. The literacy programs were implemented using top-down approach, and have not yet referred to the basic functional needs of students.

The performance, sensitivity, and corrosion protection on the QCM sensor requirement be improved to maximize the value. Therefore, the functional material coating was carried out. The addition of the polystyrene and ZnPc deposited using the vacuum evaporation method. This study intends to the morphology structure and effect of the coating, to improve performance through the annealing process based on the impedance value at QCM. The frequency measurement before and after the coating process was carried out with a variation of the deposition time, which is 1 minute 30 seconds, 1 minute 45 second, 2 minutes, 2 minute 20 seconds, and 4 minutes. The coating and annealing resulted from the surface structure of the QCM sensor are smooth, small porous, and homogeneous. In addition, the impedance to frequency graph indicates a low damping effect means the QCM sensor does not respond viscoelasticity.

The lifestyle of Indonesian people who are very consumptive makes it difficult for people to invest. This can be shown in the number of capital market investors in Indonesia which is only 0.61% of the total population. The low level of financial literacy in Indonesia is one factor. Many people do not understand finance so they cannot manage finances properly. In this study, we look for 130 respondents who are college students to find out how financial socialization and financial experience influence on investment intention through financial literacy. The theory used in this research is theory of planned behavior and social learning theory. In this study, financial literacy can only mediate the financial experience of investment intention. The results of this study are in accordance with the theory of planned behavior in which one of the elements is perceived behavioral control with self-control factors originating from within, namely experience so that the financial experience is expected to generate interest in investing.

Located on the equator, Indonesia is blessed with abundant sunlight. With current advances in solar cell and photovoltaic technology, sunlight can be exploited on a large scale, among other things, to be converted into electricity. This paper reports the results of the community service with a focus on the energy sector that took place in Wonosalam Hamlet. The method used was Community Based Research (BCR), where there are three stages of service, namely providing education to the local community about the benefits of sunlight and its use using photovoltaic, photovoltaic installation, and a feasibility study. The results show that with the current usage pattern, a dedication project of IDR 10,000,000 can save energy by 0.48 kWh / day, which is equivalent to around IDR 258,241.28 / year. In addition to the economic benefits that may not bring significant benefits, the broader impact of this project is expected to have an impact on how local people view the use of solar energy as an alternative energy source.

Oral folklore tradition is a unique phenomenon in West Borneo. This study aims to gain the lecturer's perspectives and reflection toward its implementation as a project-based activity for encouraging university students to transform local folklore into texts in English. It combines Finnegan's instructional procedure, and Gordon's synectic model and the creative state, which has been defined as creative instruction. Multiple observations and an in-depth interview with the folklore lecturer were conducted for this qualitative investigation. The lecturer is recognized as being exceptionally representative of this study employing purposive sampling under lived experience study because of his proficiency and enthusiasm. Having this creative instruction under supervision makes it clear that there is more room for the student's imagination and creativity to grow throughout this project-based activity. It gives them freedom to freely pursue their interests. Without excluding the possibilities of use in areas where there is still local folklore, this creative instruction is specifically suited for regions that are still rich in oral tradition. Further research is essential, nevertheless, as this study does not go into great detail on the perspectives and involvement among various students, the diversity of cultures and geographies, or the advancement of artificial intelligence (AI).
