Waste management is necessary, given the adverse effects on health and the environment. Waste becomes a breeding ground for disease-causing organisms and carriers. Garbage can also pollute the environment and disturb the environmental balance. The first effort in integrated waste management is sorting, starting from sources of waste producers, from households, markets, industries, public facilities, commercial areas, and other sources. Trash has economic value if appropriately managed. Waste can be processed into new energy in various forms, for example, recycled paper or compost.For this reason, it is necessary to educate the public about preventive measures, limitations of waste generation, procedures for sorting and handling waste from home, and simple waste management techniques such as making waste a useful material. Reduce, reuse, and recycle (3R) activities or limit waste, reuse rubbish and recycle rubbish are all activities that can reduce anything that can cause debris, reuse trash that is fit for use for the same function or other functions, and operations to process waste to be used as new products. The manager of the garbage bank, which is a social mobilizer, has become one of the spearheads in handling the garbage problem in the community. Must be able to be a social mobilizer. The purpose of the activity is to educate residents about the application of the 3R concept through workshops on waste management from home and increase the membership of the garbage bank and to socialize the utilization of "Mandiri Composter," which is applied to members of the garbage bank community. The location of activities in one of the RWs in the Depok area, namely RW 01, Cisalak Village.

Rainwater is one of the potential clean water resources in urban areas, such as DKI Jakarta, which has not been used optimally. Related to this, community service activities had been carried out raising theme Rainwater Harvesting (RWH). This agenda was aimed to give education and understanding of RWH to teachers and students of SDN Meruya Utara 12, 13 Pagi and 15 Petang as one way how to conserve rainwater to provide clean water. These activities consisted of the socialization and installation of RWH in schools with a total capacity of 2000 L, where each 1000 L placed at the front of the school for hand washing and in the mosque for ablution purposes. Then agenda was continued with training how to work, to operate and to maintain the RWH equipment. The mass of collected rainwater was distributed into 2 filter tanks before entering the clean water supply tank and ready for use during the dry season. After the RWH had been tested, school residents could feel the benefits. It could reduce the volume of rainwater falling down from the roof of the school building and run-off that occured in the school area so as to avoid flooding. This instalation was able to provide sufficient clean water so that it could reduce the need for using groundwater for daily use. Through this program, school residents have understood the principles of work, how to operate, maintain and can benefit from this RWH.

One of the substitute for sucrose is xylitol. Xylitol is a sweetener that has excellent properties for food development and pharmaceutical products. Xylitol can be obtained from the hydrolysis of xylan into xylose, and then converted into xylitol with fermentation by using Candida tropicalis yeast. Corn cob as agricultural waste is one important source of xylose because xylan content in range of 12.4 to 31.94%. The success of the fermentation reaction is influenced by several operating parameters, such as raw material type, the type of yeast used, the ratio of raw materials for fermentation reactions, temperature, pH conditions, and time. Xylitol production in this research was conducted through several stages such as pretreatment of raw material, hydrolysis, xylose treatment, and fermentation. Corn cobs were used as raw material for source of xylan. The variables of fermentation were time and temperature i.e 12, 24, 36, and 48 hours and 30, 34, and 37oC respectively. This research revealed that the optimum condition applied at 30oC and 48 hours with yield 0.558 g xylitol/g xylose. It showed that the effective growth of Candida tropicalis occur at 30oC and 48 hours.

Wastewater Treatment Plant (WWTP) is one of the infrastructures and systems in the manufacturing industry. This system serves to treat wastewater coming from boiler machines, which are used to produce steam to support the tire and tube production process of manufacturing companies, which are the object of our research. Wastewater from this boiler machine is alkaline and contains solids that are harmful to the ecosystem and the environment, so it needs to be processed so that wastewater can be discharged into drains. The process is not by following the standards; it can affect the quality of the process water so that water that is discharged into drains or water bodies violates government regulations. In this case, the pH standard of water is in a neutral state whose values are between 6 and 9 and is clear in color. Therefore, we conducted research that is designing a system to control and monitor the process at the wastewater treatment plant automatically. The design of this control system is done by adding sensors and actuators that are connected to the modular PLC that is the control system. This system is also designed to be connected to a PC (Personal Computer) as a monitoring system so that the process can be monitored continuously. Display interface created using HMI (Human Machine Interface) software. This is because many features that allow for a more attractive appearance. With this system, it can be sure that the boiler wastewater treatment process is more consistent and efficient in maintaining pH standards, and the process is monitored in real-time.

The Jakarta regulation for waste cooking oil (WCO) shows the desired WCO to Biodiesel supply chain through the DKI Jakarta Governor Regulation Number 167 the Year 2016. Still, the implementation of said regulation proved inefficient. The study aims to analyze the risks in the supply chain because the WCO to Biodiesel supply chain is vulnerable to different risks than the typical supply chain and the green supply chain. The method used in this research is the group analytical hierarchy process (G-AHP) approach to create a consensus model between actors of the supply chain. Deep interviews were conducted with six experts to identify the risks and the normal scale was used to quantify their preference. Then, the PriEst software assisted the risk weight calculation, AHP matrix validation, and consensus modelling. The findings show the supply chain is vulnerable to 23 risks, categorized into six risk categories. The three risks that cause the most uncertainties in the supply chain are supply chain design risk, key supplier risk, and financial source risk. Technology risks and asset failure risks are the least concern because most WCO conversion is not done in Indonesia. These findings would be useful for the government to focus its effort on the most critical risks.

The process of development has effect on the existing water catchment area, currently the normalization of the water area is being carried out. The water body is passed by various kinds of waste; domestic and industrial waste, causing water bodies to contain nutrients. Nutrients are a food source for existing phytoplankton. The amount of nutrients and phytoplankton affects the level of fertility and trophic status of each of these water bodies. Samples were collected from Epicentrum Pond, Lake Sunter, Citra Lake 6, Lake Citra 8, Setu Rawa Badak Jatijajar, and Situ Cilodong. The result shows that are samples classified in the class II water quality category according to PP No. 82/2001. The classification is based on the concentration of pH parameters, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Phosphate and Nitrate. While the classification of aquatic fertility is based on the abundance of phytoplankton. The result shows that Epicentrum Pond, Lake Sunter, Lake Citra 6, Lake Citra 8, and Setu Rawa Badak Jatijajar are included in mesotrophic, while for Situ Cilodong are included in oligotrophic. For the classification of trophic status according to PERMENLH No.28/2009 (based on the parameters of nitrate, phosphate and chlorophyll-a), the Epicentrum Pool is included in the oligotroph to eutroph. Whereas for Lake Sunter, Setu Rawa Badak Jatijajar, and Situ Cilodong are included in oligotrophs to mesotrophs. And for Lake Citra 6 and Danau Citra 8 have trophic status from oligotrophs to hypereutrophs.

Used cooking oil are oils that have been used for cooking in restaurants, hotels, food industries, and households. They are dangerous waste when inappropriately disposed since it can interrupt the sewer system or be illegally reprocessed. To combat the issue, the government of Jakarta designed the UCO to Biodiesel supply chain in the Governor’s Regulation number 167 of 2016. However, it has yet to manage households despite potentially producing 210.465,31 litres of UCO per day. The goal of this community service is to create a collection system and to increase awareness of the dangers and potential of UCO in Bassura City Apartment, located in East Jakarta, which did not have UCO collection system. The collection system considers sustainability in terms of not only the environment but also social and economic. The community service is split into five steps: creating local partnerships, supply chain planning, awareness raising by socialization, monitoring and evaluation. Local partnership was created between the local mosque Al-Falah as local UCO collector, BeliJelantah the medium sized UCO collector, and Universitas Bakrie. UCO collected by Al-Falah is bought by BeliJelantah at a rate of Rp4,000.00 /litre. BeliJelantah provides basic equipment such as jerrycans and sieve. Socialization was partially done regularly before sermon and online due to Covid-19 restrictions. Since the implementation of the collection system, Al-Falah mosque has collected 33 Litres which was converted into Rp134,000.00. Sustainability of the collection of used cooking oil will be carried out by residents and the DKM Masjid in direct coordination with BeliJelantah by taking a minimum of 2 jerrycans with a volume of 18 litre or the equivalent of 36 litre. This system can be scaled up by increasing partnerships with more local groups and local management.
