Abstract
The processing of agricultural products is one of the pillars of the development of agro-industry in an area. In LabuhanKertasari Village, the main products from the agricultural sector are seaweed, hybrid maize, and coconut. However, farmers only sell agricultural products in the form of raw materials without processing them first. Processed products certainly have a higher economic value than raw materials. For this reason, this research was conducted to process seaweed and coconut into masks which were then tested for the antioxidant activity of the masks that were processed. The research conducted was a laboratory experimental study where seaweed and coconut were first processed into a powder. The treatment given is processing seaweed into powder with an alkaline process and without an alkaline process. Then, mixing seaweed powder and coconut powder with three ratios, namely seaweed powder: coconut powder (1: 1, 2: 1, 3: 1). The results showed that the antioxidant activity of the masks 1: 1, 2: 1, 3: 1 were 743,9 respectively; 513.69; and 406.23 (with alkaline seaweed powder) and 193.67; 174.09; and 149.10 (with seaweed powder without alkalization). The result showed that a mask with a ratio of 3: 1 without the alkalization process is the mask with the highest antioxidant activity value and suitable for the skin.

Published: April 2021

Abstract
The isolation of secondary metabolites can be used by students for laboratory activities in the natural product chemistry course. The laboratory experience of isolating secondary metabolites will be useful for students to isolate secondary metabolites in other plant species whose chemical content has never been reported. In this laboratory the student isolated artelasticine from Artocarpus scortechinii. Students learn about extraction, fractionation, purification, and structural elucidation through the natural product chemistry laboratory activities. Various chromatography techniques are used to obtain pure artelasticine compounds. The artelasticine structure was determined based on UV, IR, 1H-NMR and 13C-NMR spectroscopic data. The laboratory method allowed students to readily understand the process of isolating artelasticine.

Published: April 2021

Abstract
Indonesia is facing not only a severe problem of solid waste management and river sustainability but also a lack of community awareness in managing the environment. This paper explores community engagement activities conducted in Bintang Alam, Karawang, Indonesia, to improve the community concern regarding the Citarum River, which is located close to the community under study. This community of Bintang Alam has been involved in constructing a trail along the river to provide a shortcut from a housing complex to the nearest mosque and planting fruit trees along the riverbank. The waste composition was analyzed by Indonesia Standard of SNI 19.3964.1994. To reduce the amount of waste disposed of in the river and landfills, the residents favor the development of a waste bank. Eight months of observation documented excellent progress in residents’ awareness of the importance of managing the trail, eliminating waste disposed of along the river banks, but no improvement in developing a waste bank. It has been suggested that community engagement involving multiyear grants might make more continuous advocacy in the community possible. The characteristics of funding, which is in the form of a grant with a prescribed deadline, often hinder sustainable advocacy.

Published: April 2021

Abstract
The Indonesian batik is a potential product to support the economy of Indonesia. In spite of its potential in supporting the economy of Indonesia, the water pollution caused by batik production by Small & Mediuam Enterprises (SMEs) needs to be addressed, as it leads to water scarcity since the batik production tends to consume a huge quantity of water. This research was conducted to identify key factors that influence water use for batik production among batik craftsmen, and explain those factors using the concept of circular economy. This study was conducted using qualitative method through focus group discussion (FGD) and in-depth interview as data collection strategies and quantitative data collected as secondary data. Our study found that some practices of the batik craftsmen have shown to fit to the circular cycle, although the dischargement of wastewater into waterways still fits to the linear model. Using secondary data, the direct water use for batik production were varies from 3.33 L/pc to 235 L/pc, depending on the craftsmen. If water footprint approach is to be used, the water use will be much higher. Finally, four key factors affecting the water use are discussed in this study and efforts that can be proposed to reduce the ratio water/product as well as maintaining water as a resource, as indicated by circular economy.

Abstract
Waste treatment facility, known as UPS, in Depok City is one of component in waste treatment for handling organic waste. However, carrying capacity of UPS and its ability to process of organic waste from citywide were low although 30 unit of UPS has been built over the years. The objective of this research was to map current practices and projections on waste and organic waste generation, and current organic waste collection services coverage area as well as to assess the service level of UPS at each sub-district. The amount of waste generation in 2018 is approximately 594,450 tonnes/year and projected will increase up to 886,589 tonnes/year. The organic waste fraction was projected 44% and will grow at a rate 3.9%/year in the period of 2018-2028. The amount of organic waste in 2018 is approximately 272,850 tonnes/year and increased up to 390,098 tonnes/year in 2028. Each resident projected will generate organic waste at about 118 kg/capita/year. The results showed that Cimanggis and Sukmajaya were sub-districts with the highest amount of waste and organic waste generation. Nonetheless both were having only one UPS and smallest collection services coverage area as well as high number of populations to be served for each UPS. Organic waste collection service coverage area can be distinguished by 2 schemes which were local and municipal services. It is found out that 22 UPS served for local services and 8 UPS served for municipal services. Each UPS covered averagely 16% of each total area.

Abstract
Efforts to reduce the impact of earthquake disaster have been made by the government, continuously. To decrease the casualties, an effort to be done is to construct housings and public infrastructures following the earthquake-resistant role or building code, especially in cities with high vulnerability and population. For this reason, an earthquake hazard microzonation map is crucial. Microzonation of earthquake hazard in Banjar City, West Java, Indonesia, was conducted by mapping the surface soil classification. Banjar is an essential city in West Java, connecting Bandung and the cities in the southern part. The microzonation mapping was done using the MASW (Multichannel Analysis of Surface Waves) method. The fieldwork of Vs30 measurements has been conducted in February 2020. We recorded 31 MASW sites in the entire Banjar City area with the distance between the locations approximately 5km. The results of this study indicate the surface soil classification in Banjar City in detail and precisely. The eastern part of the city shows a relatively softer surface soil structure compared to the western part. Comparison of the microzonation map obtained from the measurements with empirical Vs30 map (average shear waves velocity down to 30m), geology structure, and topographic data, showing good agreement. The earthquake microzonation map is recommended to be considered one of the references for developing the building code.

Abstract
Vegetation cover is a critical indicator and sensitive in degradation land. This study aims to explore the comparative analysis of vegetation index in the ex-mine reclamation area. The study is conducted on 2.03 ha area reclamation planted in 2017. The analysis is performed by measure Normalized Difference Vegetation Index (NDVI) from 2017 to 2020 using the Sentinel-2 satellite imagery dataset and processed by ArcGIS Pro 2.6 software. RGB drone photogrammetry acquired in April 2020 and vegetation photos featured with geotagging is used to validate vegetation index analysis. The result shows NDVI first and second-year revegetation demonstrates no significant improvement (less than 0.33), nevertheless third and fourth-year revegetation shows dramatically increase of NDVI, respectively 0.369 and 0.417 with the percentage of healthy vegetation 68.13% and 81.39%. This shows that NDVI and the percentage of vegetation health improve over the year.

Published: April 2021

Abstract
This research aims to discuss actors’ network in handling flood disasters in DKI Jakarta in January 2020. With the increasing number of disasters globally and in Indonesia, the discussion about non-government actors’ role in disaster response is relevant to disaster management studies. Disaster response, as one of the disaster management phases in the case of flood disasters, is crucial for reducing the impact of a catastrophe and increasing the public sector’s resilience and society after a disaster happens. This research was conducted with mass-media content analysis, using the keyword “DKI Jakarta flood” to collect published news between 1-6 January 2020. Then, the collected news was analyzed with Discourse Network Analyzer. The analysis found that there were contributions from both government and non-government. Food support is the most common type of contribution that was chosen for disaster management assistance. The private sector and community organizations were the non-state actors that played a huge part in post-disaster aid. Although there are roles of non-state actors in disaster management, there are obstacles in its implementation. Some of those are unsupportive regulation, the absence of an institutional framework, and various actors’ commitment to collaborative disaster management.

Authors: Kusumanagari Indira , Ellisa Evawani 
Published: April 2021

Abstract
Nowadays, it is increasingly difficult to find numerous green spaces in a city. This situation caused the conversion of green land into a built area, resulting in a lack of interaction between humans and nature. One form of urban greenery that can be easily created and brings many benefits to humans is community gardens. Community garden utilizes vacant lots to create multi-functional space for the people—gardener and non-gardener. Literature and precedent studies are conducted to understand how community gardens work as a social space that produces crops as a base knowledge to analyze the following study case. This study focuses on observing the realization of food security in a community garden at Malang, Indonesia, named Cemara Hijau Farm. The community garden uses most of its planting area for functional and active food production. However, it is still in the early stages of food security and still has not met the community’s food needs on a housing scale, as can be seen from the production and the arrangement in the planting area. Even so, existence can increase public awareness of the importance of food security.

Published: April 2021

AbstractClimate change has the most severe impact on women, but studies on adaptation in a gender perspective are still limited. The purposes of this study were to find out: (1) gender role changes in response to climate change, and (2) the impact of gender role changes on the vulnerability of women. This study was conducted on the peat-swamp ecosystem in Pulang Pisau Regency, Central Kalimantan. Gender roles in natural resource management in adapting to climate change in the peat-swamp ecosystem were descriptively qualitatively analyzed which emphasized relations and gender roles in the household. Data were collected using structured questionnaires. This study used documentation methods with secondary data types. From the results of the study, it can be seen that the gender role of women is divided into three, namely productive roles, reproductive roles, and social community roles. Climate change in Pulang Pisau Regency will interact and be sustainable with gender inequality and which disadvantages women than men, especially among the poor community, so that access to the availability of natural resources is needed in order to solve existing vulnerabilities and increase more real participation in the current climate change adaptation process.
The impact of loan to value to property credit growth sustainability in Indonesia
Authors: Taufik Agus , Soesilo Nining I 
Published: April 2021

AbstractAfter the 2008 global financial crisis triggered by the subprime mortgage in the United States, financial services authorities in various countries increasingly realized that surveillance and regulation of financial institutions were not enough only through micro-prudential approach, which intended to maintain individual financial institutions, but required macro-prudential surveillance and regulation in maintaining financial system stability. The macroprudential policy aims to limit systemic risks occurring in financial distress conditions that lead to broader economic losses. One of the macro-prudential policy instruments applied by the financial services authorities in various countries, including Indonesia, is the Loan-to-Value ratio limitation. This countercyclical policy is intended to control the rate of growth in property credit. This paper discusses the effects of limiting the Loan-to-Value (LTV) ratio by Bank Indonesia on the growth of bank property credit in Indonesia. Using ordinary least squares, the results of this study conclude that adopting a tightening LTV policy when economic growth high has a significant influence in holding back the pace of five months of property credit growth after the policy was issued. While the LTV policy’s implementation, which is loosening when economic growth is slowing down, has no significant effect in driving the pace of property credit growth.
Perceived threats looming on SDG of peace and justice: Effects of investor’s identity, symbolic and economic threats on attitudes towards FDI
Authors: Adira Neysa , Halida Rizka 
Published: April 2021

Abstract
Foreign investment has always been a polemic in Indonesia, facilitated by provocative undertones on several media outlets. However, how this information can influence people’s attitudes towards foreign investment has not been explored much. This research aimed to understand how foreign investment information from different countries could trigger threats and, consequently, influence people’s attitude toward foreign investment with the framework from Integrated Threat Theory and information processing. As much as 559 participants participated in an online experimental survey. They were randomly grouped into six experimental groups with 3 (investors cue: China, Saudi Arabia, US) x 2 (threat: symbolic, economic) and one control group. Mediation analysis showed exposure to threat laden information influenced the formation of negative attitudes towards foreign investment through systematic processing by activating economic and symbolic threat perceptions. This effect significantly appears on participants exposed by information containing the economic threat and symbolic threat from China, but not from Saudi Arabia and the US. This result indicates that support towards foreign investment is still heavily related to sentiment to Chinese ethnicity deeply rooted in Indonesia which can hinder the goals towards establishing peace, justice and strong institutions.
