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]

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.
