According to Indonesia's National Guidelines on Green Buildings (Kemen PUPR No,21,2021) called Penilaian Kinerja Bangunan Gedung Hijau (BGH), green buildings are mandatory for new and existing buildings. As environmental concerns grow, the Government uses these ratings to control energy consumption. A government initiative aims to increase demand for environmentally friendly buildings. This paper evaluates BGH's green building rating system for project certification in two Indonesian cities, Jakarta and Padang Paser Utara. Jakarta is the capital of Indonesia, the largest and one of the most populous urban city in Indonesia. Moreover, the new Indonesia capital city, Nusantara, will be built in Penajam Paser Utara, East Kalimantan. Using the results of this research, recommendations and suggestions can be given related to the design of green buildings both in Jakarta and Penajam Paser Utara. Evaluations will be conducted on simple residential buildings. The results of these studies indicate that designers and architects may have difficulty incorporating this rating systems into their designs. An evaluation of BGH ratings and sustainability analysis can be performed with building information modeling and a conceptual framework is presented toward the end of this paper. A rating system's success depends heavily on discussion among all stakeholders, including architects, engineers, environmentalists, governments, and communities. Indonesian experts in the building sector should take part in and contribute to this project. [ABSTRACT FROM AUTHOR]

On data that are not normally distributed, classical linear regression is developed into the Generalized Linear Model (GLM). One of them is logistic regression which is used for binary discrete data. A different strategy is to consider all variables (response and predictors) to be random observations from the joint probability distribution. A model with dependencies should be used because some factors are dependent. The copula model, one of which is the Gaussian copula, is a popular technique for creating multivariate models with dependencies. The Gaussian copula regression model (GCMR) is a general structure that can be used to model any form of dependent response. The Gaussian copula blends the ease of interpretation of marginal modeling with the flexibility of the dependency structure specification. In this case, the estimated parameter is the regression coefficient and the error is expressed in the dependency structure. The model estimation uses the maximum likelihood method. This paper aims to apply the GCMR model to time series data where the dependent variable is discrete with a binomial distribution. A case study was conducted to see the effect of weather factors on Covid cases in DKI Jakarta. The regression model used is binomial data logistic regression with the dependency structure expressed in the correlation matrix with the assumption that the error is obtained from the ARMA(p,q) process. The dependent variable is the number of Covid-19 cases and the independent variable is the maximum temperature, average temperature and humidity. The data are a daily time series with a range of March 1, 2020 to April 30, 2022. Based on the GCMR model, Maximum temperature, average temperature and Humidity have a significant influence on the number of Covid-19 cases in Jakarta. For this case study, the results show that the GCMR model is better than logistic regression analysis. [ABSTRACT FROM AUTHOR]

This paper describes the development of a blended-based sustainable training model. The blended learning model is used to overcome participants' limited time constraints in ongoing training to increase the competency of tourism village community empowerment facilitators. The research method used is development research. The research subjects were community empowerment facilitators in tourist villages, DKI Jakarta, and West Java. The data collection techniques used were observation, interviews, and literature review. Data analysis in this research was carried out using qualitative descriptions. The study results show that conceptually implementing a blended learning-based continuous training model increases facilitators' competence in empowering the Tourism Village community through the stages of input, process, and output analysis. In the input component, the training manager maps the competency of the facilitator's objective conditions; the training process component uses an andragogy approach where participants have self-concept practical experience and can overcome the problems they face; and the output component produces tourism village facilitators who master three competency elements, namely basic, core and special.

The aim of this paper is to analyze students' chemical literacy through implementing an Ethical Dilemma-STEAM teaching model in chemistry acid and base lessons. The model is designed to engage students in values-based learning through dilemma stories that pose environmental problems to be solved through the development of an interdisciplinary project. The study involved 40 grade 11 students from a high school in Jakarta, Indonesia, during the 2021/2022 academic year. A qualitative research method was employed to investigate students' learning experiences through classroom observations, semi-structured interviews, reflective journals, and a chemical literacy test. The model engaged students through five steps of learning: value reflection, problem-solving and decision-making, content integration, STEAM integration, and transformation. In this study students were challenged to develop a jet-powered boat as a solution to an inter-island mobility dilemma. The study found that the Ethical Dilemma-STEAM teaching model supported students' chemical literacy development. The study demonstrated that students were encouraged to think critically by applying their conceptual understanding to practice. They were motivated to look closely at chemistry issues in everyday life, an indication that this model could be used as an alternative way to engage students to see the relevance of chemistry concepts and their application to the local environment. The paper also addresses the difficulties researchers faced in implementing an innovative approach to chemistry education during multiple COVID-19 outbreaks. [ABSTRACT FROM AUTHOR]

The environmental crisis is a big problem that challenges human life today and in the future in line with the industrial era 4.0. The environmental crisis is a concern for all parties, including those involved in the religious field, especially in the current industrial 4.0 era. Various efforts continue to be made to preserve the environment in various ways and different approaches. The perspectives of religions on the environment can be a source of inspiration and solutions for efforts to build awareness of the Indonesian people to care about the environment. Online interviews were conducted on figures who understand their respective religions well who live in Jakarta, Bandung, Malang and Denpasar City, Bali. This paper finds the environmental perspective of religions from the interviewees as an epistemological framework for positive-constructive efforts to overcome the current environmental crisis. To foster environmental awareness in line with industry 4.0, it is necessary to create a digital technology platform in the form of a virtual tour that contains knowledge and educational content on environmental care as a means of socializing values for the people of Indonesia. The virtual tour is expected to be an educational instrument that can change the mindset, empathy, attitude, and action patterns of Indonesian people to care about the environment.

There are three important elements that need to be harmonized so that the Sustainable Development Goals (SDG's) can be achieved, namely economic growth (economic growth), social inclusion (social inclusion), and environmental protection (environmental protection). The Environmental Performance Index (EPI) 2020 places 180 countries on environmental health and ecosystem vitality, Indonesia ranked 116th. The indicators provide environmental policy targets, environmental performance and provide practical guidance for countries aspiring to move towards the sustainable future. Environmentally sound development is also supported by the government at the policy level in the form of Regulation of the Minister of Public Works and Public Housing of the Republic of Indonesia Number 21 of 2021 concerning the Assessment of Green Buildings. Through this regulation, the government wants to encourage the realization of the implementation of sustainable buildings that are characterized by efficient use of resources and their contribution to reducing greenhouse gas emissions (GHG emissions). The target is to reduce GHG emissions based on DKI Jakarta Governor Regulation No. 131 of 2012, namely from non-provincial buildings of 1.5 million tons of CO2 emissions in 2020 and 5.5 million tons of CO2 emissions in 2030. While the target of the provincial government building itself in 2020 is 49.4 thousand tons of CO2 emissions and in 2030 of 129.5 thousand tons of CO2 emissions. This paper is intended to evaluate the application of Green Retrofitting in Existing Office High-rise Buildings, and proposed alternative ways in order to improve efficiency and effectiveness of Green Retrofit in Existing Office High-rise Buildings development and financing.

A high-speed train is a form of transportation that connects between distant places, in this case, town to town of Jakarta and Bandung. Travel time using this means of transportation decreases since there will be no congestion as it uses dedicated railways along its travel route. During its journey, it will encounter many tunnels like the Walini tunnel. Many aerodynamic phenomena will occur and affect the train while entering, inside, and exiting the tunnel. These events will affect the whole-body surface of the train, the tunnel, and the nearby environment. The focus of the analysis of the effects is on the train's nose, influenced by the velocity and pressure that the train produces. Pressure and velocity inside the tunnel can be related to the piston effect. The pressure difference that the high-speed train brings from the outside environment into the tunnel at high speed is affected. Pressure is built up in front of the train, especially at the nose of the train. Due to its micro-pressure breakage that needs to travel to the rear part of the train to stabilize the aerodynamic condition before it becomes stable when 2-3 lengths of the train have exited the tunnel. In this paper, we will analyze the train nose shape's difference in affecting the piston effect inside the tunnel. The parameter used is when the entire train has entered the tunnel and is about to leave since the effect can be clearly seen at this particular time. [ABSTRACT FROM AUTHOR]

To get the OTTV value, you must first calculate the solar radiation value. Solar radiation occurs as a result of the sun's heat being exposed to the surface of the building and then goes inside so that the air temperature inside the building gets hotter. The solar factor is one of the elements of solar radiation which is important in determining the overall thermal transfer value for each outer area of a building. The availability of solar factor data in one place is very important to use for building design purposes. Calculating the solar factor is very difficult, moreover, SNI only contains data for the city of Jakarta. There are several ways to calculate the solar factor, with available SNI tables or by laboratory experiments or direct measurements of sunlight. So to make it easier for the designer, we propose to use the rule of thumb formula. The method used is based on local solar factor data, then a radian angle is made from 0 ° -360 °, which results in an ellipse shape in an equation. This paper concludes that the Rule of thumb formula is very helpful for architects in calculating the SF value and can also complete the table in SNI: 2011, which only contains the SF value for the city of Jakarta, meaning that it only applies in Jakarta, so similar research is needed to get the SF value for other cities in Indonesia.

Most small shoe industry are still using traditional machineries to conduct their day-to-day operations. However, there is an increasing need to improve its production line in the hopes of meeting the demand and improving the quality of the product at the same time. By doing so, competing with the other competitors around Jakarta in the long run will be possible. Therefore the 200 cm x 39 cm x 45.5 cm conveyor belt is designed to sort shoebox according to its color. When the system figures out the color of the box, then it will automatically count the number of the box with that particular color. Hence, this paper concludes that it can conduct automated color sorting and also calculating the number of shoebox that went throught the conveyor belt, while being able to see the updates remotely through a smartphone application.

The objective of this paper is to present how native Jakartans, or Betawis, are transforming their traditional livelihoods in the wake of four decades of urbanization. Specifically, this paper looks at the Rawabelong neighborhood known as a location to buy decorative plants, flowers, orchids, and plant-related accessories for decades. This primary research, including historical analysis and timeline mapping, site visits and analysis, and interviews with the local Betawi populations, was conducted as part of Tarumanagara University's Urban Lab in the Department of Real Estate and Urban Planning. The findings reveal both a loss of traditional livelihoods and neighborhood character due to urbanization, as well as the existence of resilient pockets of Betawis who have not only continued their traditional livelihoods but also used creative means to evolve their business along with the process of urbanization. We learn from the investigation that there persists a large demand for these small businesses, that the continuation of these businesses and activities are essential to the distinct character of Jakarta urban culture, and that the physical spaces resulting from these activities are unique and holistic in an increasingly acrid urban environment. By presenting these results, the Urban Lab team aims to bring recognition to the importance of such areas to the fabric and culture of Jakarta, as well as initiate discussions amongst stakeholders on how to maintain and enhance the livelihoods and physical spaces such as those present in Rawabelong.

In this paper, the researcher analyzes the architecture of cultural heritage temples with a common thread with Chinese culture. The paper's objective was to explore the element of this heritage and historic temple building in the eighteenth century that stands a sustainability architecture for decades, including the interior layout based on Chinese character and the temple's architectural ornament. In order to preserve this temple so that it remains unique, renovations were carried out while adhering to the original architectural form of the Chinese character. This paper was to show the society about the architecture of the temple that had been preserved from time to time according to its original form that supports the character of Chinese culture in Jakarta. This research used observation and literature study to support pictures and data from the temple. Literature related to Chinese architecture had been reviewed to provide sufficient data for discussion about the elements of this Chinese temple. This paper shows that the temple still maintains the character of Chinese architecture form as when it was first founded and considered a form of preservation of the historic building. This study not only will give a good impact on society to recognize this temple but also be known as a sustainable architecture in the future. [ABSTRACT FROM AUTHOR]

Jakarta is one of the world's cities with unhealthy air quality, even during a pandemic. Unhealthy air quality is caused by air pollution from various activities, including industry, transportation, offices, and housing. Unhealthy air quality can cause many problems such as health problems, decreased productivity, financial losses, family economic problems, and social problems. The public can obtain many benefits by knowing the daily air quality prediction. Among them is that they can make preparations to protect themselves when the air quality is unhealthy. This paper aims to predict monthly air quality categories based on five indicators, namely Particulate Matter 10 µg (PM10), Sulfur Dioxide (SO2), Nitrogen Dioxide (NO2), Ozone (O3), and Carbon Monoxide (C.O.) using quadratic discriminant analysis. The model validation performance shows that discriminant analysis can predict the daily air quality category in Jakarta well. Performance measures the accuracy of 93.84%, the specificity of 96.80 %, the sensitivity of 90.41 %, the F1 score of 90.41 %, and the precision of 90.41 %. [ABSTRACT FROM AUTHOR]

Over decades, urban roads in Jakarta have been suffering from flooding due to excessive surface runoff. A majority of existing urban road pavement installation in Jakarta has been utilizing the conventional pavement type. A typical conventional pavement is ineffective in reducing the surface runoff volume, particularly during high precipitation events. All stormwater has to flow onto the drainage with extreme discharge. As a consequence, the urban roads are full of puddles of various heights and lengths of time. To reflect on this issue, the authors conducted a review paper, to sum up, the extensive but dispersed literature on commonly permeable pavements. This study reviewed porous asphalt, pervious concrete, and interlocking concrete pavers. In addition, four crucial points are highlighted as consideration: (1) the structural capability, (2) permeability, (3) water quality and (4) economic risk. This research review concluded that permeable pavement is more effective in reducing flooding compared to conventional pavement. Among those three pavement types, porous asphalt pavement is the most possible to be implemented for urban roads in Jakarta, especially for light traffic. Since this pavement meets the Indonesian national standard requirements for structural capability and has less economic risk. [ABSTRACT FROM AUTHOR]

This paper reports an innovative approach in secondary schools in Jakarta that employed ethical dilemma story pedagogy (EDSP) in an integrated Science, Technology, Engineering, Arts, and Mathematics (STEAM) project designed to engage chemistry students in ethical values learning. The study investigated how students explored their own values by attempting to resolve ethical dilemmas about environmental problems in an Indonesia context. Ethical dilemmas comprised everyday socio-scientific issues related to chemistry concepts in the high school curriculum, including pros and cons of using artificial fertilizers and disposal of used cooking oil. This qualitative research was conducted in the chemistry classes of two high school teachers. The research employed multiple data collection methods of semi-structured interviews, reflective journals, and classroom observations. The results illustrate students' successful engagement in chemistry learning, critical thinking skills, chemical literacy, ethical values, awareness of environmental problems, and envisioning of education for sustainability. The results also illustrate (i) students' enhanced awareness of their values and their agency in practicing environmental sustainability and (ii) teachers' realization that they can empower students in education for sustainability through ethical dilemma story pedagogy. The study is significant in revealing that education can play an important role in empowering the young generation in education for sustainability through an ethical values approach to their learning. The paper also addresses challenges faced by the researchers in designing chemistry-based ethical dilemma stories, integrating them into a STEAM project, empowering students, and managing time resources.

Bird markets remain part of Jakarta's cultural interests in the midst of Jakarta's development path to modernization. It brings us to a time-space imagination where birds were owned and traded to resemble the social status of a person, especially in Javanese traditions. It also, therefore, marks the migration period of Javanese to Jakarta who still retains their tradition and culture in the capital city. Today, several markets even persist in the contestation between the process of space acquisition for bird enthusiasts, the formal grids and regulation of urban development, also endemic animals, and environmental conservation. Although contested, it is suggested that the bird market reflects what Foucault implied about heterotopia. The bird market represents a liminal space of the ideal romantic-traditional society which in reality does not 'fit' under the hegemonic urban construct - yet it constructs the way we relate to urban life today. This article seeks through the possibility of exploring 'this otherness' the re-positioning of the traditional market in Jakarta today and how it constructs and is re-constructed by the dominant discourse of the city. It is also argued that this memory of a time that the bird market retains cannot be detached from the social networks of bird enthusiasts who are engaged not only in economic activities of selling, buying, or biding but also in chirping contests. Not only the social value, but the bird market also depicts a political-economic logic between traders, contests organizer, competition jury, and the market as to control - boost or suppress the price of birds and promote particular kinds of birds to be included in the competition which often leads to further exploitation of bird in the natural reserve. This paper concludes on how this nexus of the social, political, cultural, and environmental context of the existence of the bird market shapes and re-shapes the city today and how each actor related to it reflects on the transformation and potential of the bird market in the future.

Pasar Ikan Modern (PIM) Muara Baru is the first fish market built by the government as an icon of the clean fish market and fulfil sanitation standards in Indonesia. Some goals built this fish market are to increase fish consumption in the Jakarta area and change people's view of the dirty traditional fish market. Building conditions that meet the sanitary standard can prevent disease and guarantee the quality of the fish sold. A clean fish market environment and the application of good sanitation are the main important ways to keep environmental sanitation. This paper aims to identify the environmental sanitation based on SSOP (Standard Sanitation Operating Procedure) in PIM Muara Baru. This research uses the quantitative method. Data was obtained from the observation approach and survey on 30 respondents, all of whomare fish sellers. These results show that PIM Muara Baru has not fulfilled all the procedures in SSOP. From 24 proceduresin SSOP, 13 procedures (54%) were appropriate, and 11 procedures (46%) were inappropriate. [ABSTRACT FROM AUTHOR]

The textbook has been used as the main reference in most Indonesian schools. As the main reference, it has become an important source of knowledge and a tool that allows learners to acquire knowledge, skills, attitudes, and values of other cultures. Since textbooks are used with students as the center of learning, those can help support the objective of attaining sustainable quality education as it is portrayed by the Sustainable Development Goal (SDG). This paper elucidates the use of a global coursebook for local students in one national school in Jakarta, Indonesia, and how culturally relevant the coursebook is for local students. It is self-study research conducted by the first author, who reflected on and analyzed her intern teaching experience when using a global coursebook for a class of fourth-grade students. Having analyzed the textbook and the first author's reflection in using the textbook, we (the first and second authors) found that the global textbook lacks cultural relevancy and portrayal of local culture. Considering these findings, we suggest educational institutions as well as the government consider the book selection and development as important components to the educational system that is sustainable, equitable, accessible, and culturally relevant for all Indonesian children.

Twitter data provide rich and powerful information to leverage the dynamics of public perception to establish situational awareness and disaster mitigation strategies during critical times. In this paper, we perform topic modeling via Latent Dirichlet Allocation to extract topics from a collection of tweets related to Indonesia flood events in February 2021 with the query: "banjir". The extracted topics are used as one of the features to build a generalized linear count time series model with Negative Binomial distribution. We find seven major topics from the model in which tweets containing a topic about the government's role in handling the situation dominate the conversation. Taking into account a simple intervention analysis, we demonstrate a statistically significant change in the users' behavior before and after the severe Jakarta flood on 20 February 2021. Moreover, a metric evaluation demonstrates that a covariate that describes the turning point of the Jakarta flood event is convenient to build a more accurate count time series model of the tweets.

The COVID-19's rapidly spread in Indonesia is a serious concern for government. Various government policies, such as large-scale social restrictions, which is called as PSBB, and the imposing restrictions on community activities, be called as PPKM, have been applied to slow the spread of COVID-19. These policies were supposed to control people activities in many areas, especially that will invite the crowd happening. In this paper, the control charts be explored to obtain the overview of the daily new COVID-19 cases number, which is considered as a production process. The proportion of positive COVID-19 cases be observed and monitored using P-control chart. The data used is from the specimen COVID-19 test in DKI Jakarta Province, since April 2020 to January 2021. It is obtained that the process of daily new COVID-19 cases number has not been statistically controlled. It is detected some mean shifts of proportion in some point of times. Several findings indicate an upward trend, suggesting that the proportion of positive cases COVID-19 is rising. The public's conduct in Jakarta has served as a model for the government in designing policies to tackle the spread of Covid-19. However, due to the high mobility of Jakarta residents and its lack of consistency in the region, the COVID-19 process still remained out of control. [ABSTRACT FROM AUTHOR]
