Sustainable development in building facilities raises strategic issues. One of which is the construction of green buildings that pay attention to and uphold environmental aspects. The current development has not fully implemented aspects of green building construction. The legal basis and obligation to implement weak laws and regulations are some of the factors that have not enabled the growth of productive green buildings in Indonesia. Therefore, this scientific paper examines the idea of regulating the construction of green buildings in the context of laws and regulations as a binding legal basis for realizing sustainable buildings in Indonesia. The method used to analyze the subject matter in this scientific paper was normative legal research methods, by examining and exploring the idea of green building arrangements in-laws and regulations in Indonesia as the embodiment of sustainable buildings that uphold environmental aspects. Eventually, this scientific paper can reveal the ideal concept in the regulation of green building laws in Indonesia's formulation of laws and regulations.

This research aims to reveal the difficulties faced by the Indonesian government in dealing with refugees during the COVID-19 outbreak and find solutions to these problems. To analyze this phenomenon, this research used a descriptive qualitative approach. Data was collected through interviews, literature study, and supported by observation. The research result shows that the Indonesian government faces ambivalence in dealing with this problem. On the one hand, Indonesia did not participate in ratifying the 1951 International Convention and the 1967 Protocol, so Indonesia was not obliged to handle the presence of refugees. But on the other hand, since early 2020, Indonesia has been appointed as a member of the UN Human Rights Council so indirectly Indonesia must comply with all forms of international declarations on human rights. With this position, the Indonesian government must normatively pay attention to refugees in the form of access to social assistance and health facility services. Considering government limitations due to the COVID-19 outbreak, several solutions that can be taken include clarifying and strengthening the cooperation with UNHCR and IOM, expanding community-based protection cooperation, delegating part of the state's authority to local governments which deemed capable, and regulating the opening of limited work access for refugees.

This research was a quantitative research design in this study, the researcher limited discussion by stating the following research problem: "Is there any relationship between learning style on STEM students Achievement?". "Does the learning style affect their achievement?". This study aimed to find out the most dominance used by students in learning STEM and to find out whether or not an effect between right-brain and left-brain on STEM learning. The result of this study can help teachers' methods in teaching-learning. The subject of this study was the STEM students of university level. The sample of this research was 45 students. The data were collected using interview STEM education, questionnaire 5-Likert scale, and test. The data were analyzed using an independent t-test through SPSS 22.0 version. The result of this research showed that the finding effect between right-brain and left-brain dominance on learning achievement is positive result means that there is a difference between right-brain and left-brain dominance on their achievement. The level sig. (2 tailed) was greater than the level of significance (.00 < 0.05), then H0 was rejected H1 was accepted. It can be said that all students of the STEM Education Department use left-brain dominance in the learning process. Meaning that the students who use right-brain dominance have good scores and students who lowest score also use right-brain dominance but it is not suitable for them. These findings imply that students who learn analytical with left-brain dominance will be good in achievement than those who learn with the other brain dominance. The researcher suggested applying the brain dominance provided to overcome their difficulties. However, this research was expected to be developed by future researchers who had the same interest.

The operating costs of fishing vessels are dominated by the use of fuel. In most cases, a Jukung boat operated for ca 8 hours in a day requires 20 - 30 liters of diesel fuel or is equivalent to 60% of the total expenditure. TERAPAN, the solar technology installed on the roof of fishing boats, is one of the technological breakthroughs that can be employed as an alternative of replacing electricity sources from oil-fuelled generators. The outcome of TERAPAN is the reduction in ship operating costs and the risk of air pollution from the exposure of gas coming from the generator itself. The application of TERAPAN also supports the Sustainable Development Goals (SDGs) encompassing Affordable and Clean Energy, Life Below Water and Climate Action. This scientific paper aims to examine the installation and economic feasibility of solar panels to meet the lighting and navigation needs of fishing boats with a power between 450 and 900 watts. From the results, one fishing boat requires two 12 volt 50 Wp solar panel, a solar charger, a 12-volt 50 Ah battery (dry or wet), a DC to AC inverter, an MCB or switch, a control panel, sockets and two-colour power cable 6 meters long. By implementing TERAPAN, fishermen no longer have to disassemble batteries to charge at a cost of IDR 25,000.00 per battery or is equivalent to an operational cost savings of 26.04%. Further study is recommended to conduct research in terms of installing the solar panel on the ships.

Motorbikes are an essential mode of transportation in Indonesia. People utilize it on a regular basis to get to work, school, and to transfer goods. According to data from Badan Pusat Statistik, the number of motorbikes in Indonesia hit 112 million units in 2019 [1]. Because of the high demand for motorbikes in Indonesia, many individuals must rely on loans. This, in turn, leads to a rise in fraud cases because people alter paperwork. Increasing fraud incidences by faking identities and documents. Aside from the possibility of fraud, there is also the long process that customers must endure by coming to the showroom, waiting for the list, and following a series of inefficient processes, so that the customers waste their time by doing those activities that cause them to miss other activities that are more productive. Customers may minimize time-wasting activities and fraud as much as feasible by establishing this online system. Because of these issues, this paper will present a web-based system that can assist clients, leasing companies, and dealers in online transactions to ensure that all provided documents are authentic. The system was developed in the website so that can be accessed in both mobile and personal computer. The website will be made based on agile software development process called rapid application development (RAD). Finally, the Web-based online motorbike dealing system has been developed and tested to meet a whole motorbike sales business process properly without any faults, flaws, or issues. Further research will mainly talk about automatic document verification and security issue.

On the market, the number of newly founded fintech companies that involve sharia-compliant businesses has increased recently, one of them being the sharia-crowdfunding company. The company targets countries with large Muslim populations, such as Indonesia and Malaysia. Since the sharia compliance is unique, and thus it influences decision-making in a business. Therefore, we are driven to propose and develop an assessment tool to assist the investment signaling process for the sharia-compliant equity crowdfunding projects on Platform X. Platform X is one of the pioneers of real estate Islamic crowdfunding platforms investing in sharia-compliant real estate projects in Southeast Asia's emerging countries. The firm must examine new projects locally for each newly created branch country as the firm aims to open new branches in some predominantly Muslim countries. However, each newly founded branch country lacks a mature and uniform assessment tool for sharia-based projects, resulting in glaring problems in the 'portability' and time-consuming problem of assessing the projects. Therefore, this research provides a technique for assessing sharia-equity crowd fundraising decisions using a multi-criteria decision analysis (MCDA), namely TOPSIS. We combine the concept of equity crowdfunding, Islamic principles, and Sharia compliance to develop a tailored assessment tool for sharia-based projects. As a result, we present both theoretical and managerial implications, and we find that the assessment tool is robust as the evaluation result for the portability aspect and the fast computational time were successfully examined through a simple experiment.

E-commerce plays a significant role in a country's economic condition. Since the COVID-19 outbreak, it has become more popular, along with concerns about its ability to handle information security. The Zero-Knowledge Proof (ZKP) method could be a possible solution to the e-commerce payment security issue that hampers customer trust. This paper investigates the viability of an online payment framework based on the ZPK method. This method is an upgrade for authentication during the payment process in online shopping. Experiments on customers' perspectives of the payment framework based on the ZKP method were conducted and supported the perceived usefulness, ease of use, trust, control, satisfaction, and loyalty aspects of a better e-commerce website. It allows advantages for both customers and e-commerce and prevents fraud, which will increase the trust level for both sides. zkSNARK speeds up and lowers the cost of the process, but there is a risk of DOS. Future work needs to be done to handle DOS in this method.
