Abstract
The United Nations Convention on the Law of the Sea (UNCLOS 1982) affirms that the government has sovereign rights, jurisdiction, and obligations in Indonesia’s EEZ. Indonesia has an interest in protecting sovereign rights and increasing state revenues in the waters of the Exclusive Economic Zone (EEZ). That sovereign right is to use fishery resources responsibly for the benefit of the nation and society as a whole. The sole purpose of this qualitative research is to optimize fisheries utilization in the Rote Ndao Regency whose waters include the Fisheries Management Area of 573 (FMA-573) in the EEZ. The analysis had been carried out with a case study approach and then descriptively elaborated. The results showed that: 1) the use of fisheries in FMA-573 was carried out by traditional fishermen (using vessels ≤10 Gross Tonnage/GT) and fishermen using vessels >29 GT; 2) supervision is still needed for the improvement of ships and human resources; 3) there are still violations of territorial waters by traditional Indonesian fishermen. The policy recommendations that must be carried out by the government are: 1) encouraging local fishermen to catch fish in the FMA-573 area by providing stimulus for ships and fishing gear; 2) allocate budget to purchase a new fleet of ships and add supervisors; 3) increase the number of fishery instructors to foster and socialize the boundaries of Indonesia’s EEZ with Australia.

Abstract
This paper aims to examine how to protect of artisanal fishermen fishing ground and the policies that protect them. Small-scale fisher fishing grounds has to have a special attention due to their limitation. They are using very simple fishing gear, so they can’t sail far away from the coastal waters. The Fishing law give a specific attention for this matter, by limiting fishermen with 5 gross tonnage (GT) are only able to conduct their activities within the coastal waters. This study combines legal documents and the results of interviews with fishermen on 5 GT vessel. this studi of find, then the Law Number 27/2016 changed this regulation by increasing gross tonnage for small-scale fishermen from 5 became 10 GT, and it attract more serious problems for these small-scale fishermen since they have no exclusive fishing ground anymore. It will also affect to changes of fishing lane; fishing ground and vessels authorization procedure. By increasing GT, the 10 GT vessels also have rights to sail in the same fishing ground with 5 GT vessels and it’s created a potential conflict between the fishermen. So, harmonization of law is important task for the government in avoiding the overlapping rules on vessels criteria, by choosing law that prioritize on small-scale GT vessels.

Abstract
Lake Poso is one of the ancient lakes in the world. This lake is known to have high diversity of endemic fish. Several exotic fish species have been introduced to increase the fisheries production in the lake. However, it is reported that the introduced fish is one of the causes of the threat of the existence of endemic fish in this lake. This study aimed to obtain the latest information on endemic (Adrianichthyidae, Gobiidae, and Zenarchopteridae), and introduced fish in Lake Poso. The research was carried out from May to July 2019 at 17 stations on the coast and rivers of Lake Poso. Fish were collected using a seine net, tray net, and hook and line. The results showed that there were 13 species of fish belonging to eight families and 11 genera. A total of six endemic fish species were still found in this study, namely Adrianichthys oophorus, Oryzias nebulosus, O. nigrimas, O. orthognathus, Mugilogobius sarasinorum, and Nomorhamphus celebensis. Seven species of introduced fish were found, namely Anabas testudineus, Aplocheilus panchax, Channa striata, flowerhorn (Cichlasoma sp.), Melanocromis auratus, Oreochromis niloticus, and Trichopodus trichopterus. Cichlids (flowerhorn, M. auratus, and O. niloticus) have the potential to be invasive due to their adaptability and ease of reproduction in Lake Poso. Conservation of the fish endemic to Lake Poso must be a serious concern for the government, academics, and the community. Ex-situ conservation can be a strategy to conserve the endemic fish of Lake Poso through controlled captivity.

AbstractCitepus River is one of the urban rivers that pass through Bandung City, Indonesia. Visually, the Citepus River water shows relatively poor condition. This study aims to examine the water quality of the Citepus River, the results of which are used to recommend river management efforts. This research was conducted using secondary data obtained from the Bandung City Environmental Agency for the 2018-2020 time duration. Assessment of river water quality is carried out by comparing water quality monitoring results with the applicable quality standards. In addition, indexation was also carried out using the Storet method. The study results show that almost all parameters exceed the Class 2 of maximum water quality standard based on Government Regulation No. 82 of 2001 concerning Water Quality Management and Pollution Control. The results of calculations using the Storet method stated that the water quality in the Citepus River from the upstream segment to the downstream segment was classified as class D, which means heavily polluted, with the highest score in the middle segment at -54 and the lowest score in the upstream segment at -42, while the downstream segment, the score obtained is -52. Based on these results, management efforts can be recommended by determining the capacity, identification and inventory of wastewater sources, determining requirements and procedures for waste disposal, prohibiting waste disposal into rivers, monitoring river water quality, and monitoring wastewater quality.

Abstract
One of the foods favorites by Indonesian people is tofu. In the process of making tofu, it produces wastewater. The tofu wastewater must be treated first to reduce environmental pollution. To treat the liquid waste, it is using biological treatment by an anaerobic baffled reactor with bio-ball. The purpose of this study was to determine the optimum time at 75% tofu wastewater concentration. The detention time used in this study was 12 hours, 24 hours, 36 hours and 48 hours. Seeding takes time about 45 days, with the obtained VSS was 5550 mg/L. Furthermore, acclimatization in the reactor takes about 30 days, with an efficiency of removing COD of 86.3%. The results obtained that at 12 hours of detention, there is a COD allowance of 79.8%, 24 hours of detention time there is a COD allowance of 85.4%, 36 hours of detention time 86.3%, and 48 hours of detention time 88.4 %. It shows that the optimum detention time in this anaerobic reactor is 48 hours. However, the COD level was 765.3 mg/L is still slightly above the quality standard according to the Minister of Environment Regulation No.5 2014, which is the maximum COD level of 300 mg/L.

Authors: Kusumadewi R A , Wijayanti Y , Fittkow M 
Published: November 2021

Abstract
Solar water desalination system is one of the alternatives for supplying fresh water. On the other hand, some people are reluctant to use and rely on water produced by the system. Also, there are other barriers to the adoption of this system in Indonesia. This research aimed to conduct a preliminary study on the performance of solar desalination systems and identify factors that hindered its implementation. The methodology applied in this study consist of two approaches. First, the desalination system performance is determined by the quantity of freshwater produced and the quality of feed water, distilled water, and brine compared to Indonesia’s water quality standard. Second, the identification of implementation barriers was evaluated in the structural analysis method using MICMAC (the Impact Matrix Cross-Reference Multiplication Applied to a Classification) software. The performance analysis result shows low efficiency based on desalinated water produced, which ranges from 2.59% up to 9.67%. The water quality parameters of pH, turbidity, TDS, chloride, Fe, and hardness met the Indonesian water quality standard. The factor of “uncertainty of subsidies,” “niche market,” “poor solar energy data,” and “lack of policy/regulatory framework” were determined as critical barriers which have the most significant influence and highest independence.
Hydrocyclone optimisation to separate oil and water in the separator

Published: November 2021

Abstract
The conventional 3-phase separator installed cannot anticipate the increase in fluid flow so that the oil content carried into the produced water from the separator consistently exceeds the upper operating threshold. This study aimed to test the application of a hydrocyclone device to a 3-phase horizontal separator. Hydrocyclones are widely used as auxiliary devices to optimise oil separation by minimising oil carried into the produced water stream. This study made a comparison between installing a hydro cyclone at the inlet with a 3-phase horizontal separator. Applying a hydrocyclone at the inlet of a 3-phase horizontal separator increases the efficiency of the separation process in production. Proper design improvements with Hysys and flow characteristics with CFD can reduce the oil content carried in the produced water stream below 20 mg/l. The results of this study can support de-bottlenecking to increase production to a production target of above 375 kbps. A robust application of engineered hydrocyclones with correct production and operating shrouds has been experienced to optimise the separation process by up to 92%.
