Solid waste management on Nusa Penida Island is one of the problems in tourism in Bali Province. To deal with this issue, the government has implemented various policies, where the policy that becomes an essential issue is the processing of energy waste. To support this, it is necessary to study the potential of waste characteristics on the island of Nusa Penida. This study aims to analyse the characteristics of waste on the island of Nusa Penida as an energy source based on the generation and composition of waste. Solid waste generation and composition were measured based on land and marine debris data. The total waste generation on land and marine debris can reach 6364.4 kg/day and 762.8 kg/day, respectively. The waste composition materials consist of masks, plastics, metals, and biodegradable organics with a value of 4.12%, 32.77%, 19.54%, and 43.57%, respectively. Therefore, the potential use of organic biodegradable as solid fuel can reach 51,933.8 MJ/day or 14,426 kWh/day. However, in the thermogravimetric analysis (TGA) test, the residue was 18.6%.

Pangandaran is located in the southern coast of the Java Island. Some of Pangandaran fishers operate lift net (bagan) to catch fish and shrimp. During hauling process, the net is lifted manually using a roller that potentially harm the fishers. The purpose of this study was to design a mechanical roller that applicable for lift net. The analysis of design requirement, such as calculation of torque, horse power, and reduction power with gear mechanism for operating the roller were applied in this research. The results showed that the net lifting operation required 4.8 HP or 3.6 KW of diesel engine to power a hydraulic pump. For the maximum load, when the net is fully loaded with fish, the operation required 67.91 HP or 50.64 KW. It means power from the diesel motor was not enough to support at maximum load. Therefore, a gear mechanism with a ratio of 1:14 was applied. However, this method reduces the angular speed of the gear which leads to reduction on net pulling speed. Keywords: Lift net, hydraulic, horse power, power, and lifnet roller

The problem of oil pollution in the sea is starting to get serious attention from the public. This incident caused the mass death of various types of marine organisms. Many cases only become government records without any complete response. An example of a case is oil pollution in Seribu Island. It is known that pollution has occurred since 2003 and in the 2003-2004 period it was recorded that it had occurred 6 times. To prevent and control marine pollution due to oil spills, there are several prevention methods. We know that the case is difficult to do because the oil spill is very done, both in terms of time, continuous work, and in terms of the costs involved. In this study, the design and construction of oil extraction using absorbent media in the oil waste area in the water. The purpose of this research is to design and conduct a study of the efficiency of a belt type oil skimmer using durian skin waste which is moved using a solar panel. It absorbs oil from the air which can be retrieved and collected onto the vessel by providing a piping arrangement. The collected oil can be reused for various purposes.

River debris is the main problem from the negative impact of poor waste management. The composition of river debris in Jakarta consists mostly of plastic waste. Plastic waste from river debris has an opportunity for energy recovery. This study aimed to see the potential for utilizing river debris in energy recovery in power plants. This research was conducted at three sampling shelter points in Pesing, Pluit, and Perintis. Waste generation and composition were quantified using the load count method on Indonesian state standards for seven consecutive days. River debris generation in Pesing, Pluitm, and Pernting averaged 7.2; 3; and 1.8 tons/day. More than 60% (w/w) of plastic bag waste was found in the Pesing and Pluit shelters, while 67.3% was found in the Perintis shelter. Based on the calorific value of each plastic waste, the energy potential from plastic waste recovery can reach 16,197,109 kWh/year. This is equivalent to an electricity supply of 0.05% of the total electricity demand in Jakarta.

Indonesian marine debris of aquatic waste in Jakarta is managed by the UPK of the Water Agency, one of which is the Pluit Employment. Several composting methods can be used and adapted to the available circumstances and needs. The composting process is carried out by utilizing the supply of oxygen, nutrients, water, and temperature control. This study aims to analyze the selection of alternative composting systems that can be carried out for planning the composting unit at Pluit Employment. Selection analysis was carried out using the Utility Theory and Compromise program methods. Alternative 1: This alternative uses a composting system using an open bin. Alternative 2 uses a simple windrow system with garbage piled up without heavy equipment during operation. Alternative 3 uses a composting system with a static pile system with a machine turning it over. In the composting method chosen, alternative 2. The distance between compost for workers' movement space, it can reach 1 m as in the TPS 3R Technical instructions, that because it does not use machines, the land used for machine movement is reduced. Limited land can be utilized for the amount of windrow so that the amount of processed waste can be more significant.

River debris in Jakarta is generated in several locations by conventional transportation. Waste transportation with traditional models is usually not time-efficient, primarily when river debris is generated every time. Transport systems that can be used for river debris include compactor systems, pre-compactor systems, and baller systems. This research uses literature study and secondary data in determining alternatives. Meanwhile, the alternative selection was carried out using the Multi-Criteria Decision Making (MCDM) method. This study uses four criteria for selecting alternatives: initial capital, type of transport container, operation and maintenance, and processing capability. The utility value of waste transportation with compaction and pre-compacting systems does not significantly have utility values of 0.722 and 0.833, respectively. At the same time, the baller system has a utility value of 0.222. This shows that the compacted system is more suitable to be applied to SPA river debris in Jakarta. The presence of a pr-compactor can also reduce the water content in-river debris.

The Republic of Indonesia Maritime Security Agency (Bakamla RI) was formed based on the mandate of Article 59 Paragraph 3 of Law Number 32 of 2014 concerning Maritime Affairs. Bakamla RI has implemented an early warning system to ensure security and safety in Indonesian waters and jurisdiction. The Bakamla RI Early Warning System (EWS), known as a choke point for maritime security and safety, has already been built and spread throughout Indonesian waters. However, in reality, drug smuggling by sea is still common. Drug smuggling by sea is still dominant today. The United Nations Office on Drugs and Crime (UNODC) revealed that 80% of drug trafficking is carried out by sea. Narcotics transactions in the middle of the sea are very safe transactions, this is due to very weak supervision in the middle of the sea by officers. The purpose of this study is to analyze the mechanism and effectiveness of an early-stage warning system in preventing drug smuggling by sea. This study uses a qualitative descriptive method with interview data collection techniques. Research shows that the Early Warning System Series produces ship detection and assistance data that can be processed into ship anomaly information. The application of the Bakamla RI early warning system to prevent drug smuggling by sea has not been effective. The difficulty of realizing information between agencies and the weak synergy in exchanging information are the main obstacles to the efficiency of the early warning system. Therefore, it is recommended to increase the capability of the Bakamla RI Early Warning System by integrating the Command and Control Center (Puskodal) or Control Center (Pusdal) of related agencies, as well as equipping it with monitoring equipment that integrates the Early Warning System.
