Paper waste production in DKI Jakarta according to data from The Jakarta's Environmental Services reaches an average of 40% of total waste production per month for each municipality (kotamadya). On the other hand, Indonesia's necessity of construction development, notably residential home, is increasing constantly along with the amount of Indonesia's population. This condition stimulates innovation of eco-friendly, inexpensive building material with suitable strength. Since 1990's, papercrete, concrete with waste paper as substitution of fine and/ or coarse aggregate, has been studied. Its use for structural materials has evolved and required supporting research for application on larger structural components. In this research, homogeneity aspect of papercrete from domestic waste (office) is investigated along a certain height of vertical beam. To do so, Ultrasonic Pulse Velocity (UPV) propagation measurement on 5 vertical prismatic beam specimens was conducted. By using direct mode transmission, two transducerswere used through 15 cm of width. Rate of propagation can detect the density of concrete at each level since early age of concrete (2 hour after casting). It describes the distribution of material inside. This homogeneity study is beneficial in evaluating papercrete application in real beam structure in the future. [ABSTRACT FROM AUTHOR]

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]

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.

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.

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.

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.

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]

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]

The diversity of ethnic groups in Indonesia has been one of the basic factors of the growth of identity in a settlement. Ethnic Chinese has been one of the minority ethnic groups that have become a part of that diversity, after migrating from China and have settled down in Indonesia from the early century (around 1st century B.C. according to Melalatoa [1]), thus making the name Chinatown known as the settlement whereas ethnic Chinese (now Chinese-Indonesian) lived. One of the biggest Chinatown in Indonesia, Glodok area had the identity known as a trading area managed by Chinese-Indonesian from the colonial era until now, and has become a very iconic place in Jakarta for the characteristics as a Chinatown. Glodok that was formed in the colonial era became the place where Chinese identity and Dutch identity interact, and then followed by the interaction with local ethnic groups identities in the following era. Advancement in architecture that was developed in those times became the very uniqueness that makes Glodok distinctive in Jakarta. In that phase, the settlement grows in response to the society and environment growth, especially in times of modernization and new technology. In this case, does the Glodok settlement still maintain its identity in the visualization of the settlement? Or the identity itself has already succumbed through the intense modernization and rapid changing in the environment? This paper aims to identify those changes of the settlement in response to the growing environment, especially in Indonesia whereas the country has a tropical climate that affects the use of building materials in the urban space of Glodok. The methods used to obtain the data needed are literature research on the development of Glodok throughout the history and observation on the growth through the documentation of both the past and the present of the Glodok settlement, and its growth in the aspect of architecture. Therefore, knowing that Glodok does have changes in the terms of settlement, the form and facades of building, the materials used, along with the identity growth. [ABSTRACT FROM AUTHOR]

It is undeniable that the world's climate conditions are experiencing a significant quality decrease where the air around our homes, including Jakarta, are not feasible anymore where there are a lot of dangerous Particulate Matter 2.5 in the air that we breathe daily. Not only the air condition, the high demand for processed petroleum such as gasoline and diesel causes Indonesia to import where in 2018 there are 393,000 barrels per day. Of course, the budget spent to meet the fuel needs is not small, and will not decrease for the next few years, given that Indonesia's petroleum stock has also decreased. Based on these problems, Universitas Indonesia is committed to build an environmentally friendly transportation, called Electric Bus. This Electric Bus has prime mover in the form of a 3 phase induction motor. Author on this paper is doing the research to build an electric motor design used on The Bus, so that the motor can produce performance in accordance to the design specifications that is 100 kW, where three motors will be combined to produce 300 kW of power with 1200 Nm of torque. This research focuses on motor construction, as well as the selection of materials where the material used is from Indonesia so that all components of the motor are originally made in Indonesia, with the best quality and specifications. This design has been successfully made resulting a weight of 298 kg and dimensions of 630 mm x 470 mm. The results of this research are expected to be able to electrify The Yellow Buses at Universitas Indonesia. [ABSTRACT FROM AUTHOR]
