The usage of plastic has been increasing from year to year for its durable, lightweight, sturdy, easy to form, and low cost production, so that plastic becomes a popular material. Plastics have affinities with persistent organic pollutant such as PCB, DDT, PAH and phthalates that can damage the ecosystem as well as harm to human. In this study plastic wastes were collected using nets in seven stations along Baturusa watershed, sorted based on its composing resin (RIC), then measured the abundance and the density rate on each station. 36% of the collected plastic wastes are Polypropylene (02), and 24% are LDPE (04). The highest density rate of collected plastic wastes was found on Mabet river (1.36 x 102 items/m3), followed by Baturusa river, and Rangkui river estuary. These three stations are located near the settlements so that the source of the plastic wastes comes from domestic activities. The variety of waste management showed a significant impact to the amount of plastic wastes on waters. One of the plastic waste management for the settlements is to carry out 3R (reduce, reuse, recycle), such as waste bank programs and implement EPR (extended producer responsibility) programme. The successfulness of this programme can only be achieved by the active participation of the waste bank customers and the implementation of 3R principle in daily life.

Marine pollution can have a negative impact on aquaculture. For this reason, an appropriate and precise compensation calculation formula is needed. This study aims to formulate a formula for compensation calculating for aquaculture by reconstructing formula in PermenLH No. 7/2014. The reconstruction of formula was analyzed descriptively qualitatively with an expert judgement approach. The results showed that production data was a key factor in the reconstruction of compensation calculation formula. There are three reconstruction results formulas, namely compensation formula for aquaculture whose production data is available before and after pollution; compensation formula for aquaculture which only production data is available before pollution; and compensation formula for aquaculture which production data are not available

One of the functions of the coastal ecosystem is to produce environmental services that can be used for marine tourism. Oil pollution incidents at the sea have caused a decline in the quality of marine tourism objects, thus reducing the number of visitors arriving and then it has implications for decreasing the income of the people who do business at tourist area. The community's claim for immediate compensation payments requires a faster calculation method. The purpose of this research is to develop a method of assessing the economic compensation for marine tourism businesses that are affected by incidents of oil pollution at the sea. The type of this research is descriptive research. The data consists of primary data and secondary data. The steps required in calculating compensation are (1) identifying tourism businesses, (2) building a theoretical concept of compensation, (3) determining the legal basis for calculating compensation, and (4) Designing a compensation formula. The application of the five compensation calculation formulas requires 18 variables. By taking the case of an oil spill incident in the North Sea of Karawang which has an impact on Tanjung Pakis beach tourism, an estimate of the value of compensation (Rp/day) is obtained for the buoy rental service business is Rp 111,323.08, for bathroom services business is Rp 69,504.62, for food/beverage trading business on a small scale is Rp 71,510.77 and for food/beverage trading business on a large scale is Rp 188,569.23. For the next stage, the implementation of compensation needs to be verified against the impacted community and the payment mechanism so that it is right on target.

Tilapia fish farming with the aquaponic is a system of cultivation that can save land use and increase the efficiency of nutrient utilization of residual feed and fish metabolism by the plant. This research aimed to analyze the influence of different plant densities on growth, survival and the comparison of length and weight of tilapia (Oreochromis niloticus) in aquaponic system with dense plant. The experimental design used was Completely Randomized Design in time with three treatments and three replications with the level of density of vetiver (Vetiveria zizanioides) tested in this study was 400 g, 800 g and without vetiver. Nile tilapia (Oreochromis niloticus) was used with weight of 14 g, average length of 8-9 cm, and the experiment lasted for 42 days. The observed parameters was the growth of length and weight, length-weight relationship, and the survival rate. The results showed that the highest increase was in the treatment of 800 g vetiver plants with the growth of 19 g, the length increase of 2.64 cm and the survival rate of 100 ± 0.00 %. The lowest value was in the control. The use of aquaponic system in nile tilapia management with vetiver and control treatment had significant effect (P <0.05) on weight gain, length increase, and survival rate of tilapia. Water quality in all treatments generally reflected a range within tolerable limits and not harmful to tilapia growth.

Tingginya akumulasi sampah plastik di perairan Indonesia dapat meningkatkan potensi cemaran mikroplastik. Ikan dan garam merupakan bahan baku utama pembuatan ikan pindang yang keduanya berpotensi membawa berbagai bahan cemaran, termasuk mikroplastik. Tujuan penelitian ini untuk mengetahui cemaran mikroplastik pada ikan pindang yang diproduksi oleh 5 pengolah di Tanah Sareal, Bogor Utara, Parung, dan Ciampea. Kandungan mikroplastik dianalisis dari 5 jenis ikan, yaitu bandeng (Chanos chanos), tongkol (Euthynnus affinis), layang (Decapterus russelli), semar/etem (Mene maculata), dan kembung (Rastrelliger kanagurta), yang meliputi daging ikan segar dan produk pindangnya, garam, dan air rebusan pindang. Identifikasi mikroplastik dilakukan terhadap hasil destruksi dengan H2O2 secara mikroskopis dan dikonfirmasi dengan FTIR-UATR. Hasil penelitian menunjukkan jumlah mikroplastik pada daging produk pindang berkisar antara 0,22±0,15 dan 0,69±0,12 MP/g atau meningkat sekitar 11-19% dibandingkan dengan bahan bakunya. Sebanyak 0,17±0,02 MP/g ditemukan pada sampel garam dan 0,10±0,02 MP/mL pada air rebusan pindang. Analisis FTIR-UATR menunjukkan bahwa mikroplastik yang dominan adalah polipropilena (PP) sebanyak 54% dalam bentuk fragmen atau film, dan polietilena (PE) sebanyak 46% dalam bentuk fiber atau fragmen. Perkiraan paparan mikroplastik akibat mengkonsumsi ikan pindang yang didasarkan pada tingkat konsumsi ikan pindang masyarakat Indonesia adalah 2,345±603 MP/orang/tahun. Kondisi tersebut mengindikasikan potensi bahaya apabila dikonsumsi terus-menerus, karena mikroplastik yang dapat bersifat akumulatif. Dengan demikian, perlu diupayakan pengurangan kandungan mikroplastik pada bahan utama ikan pindang dan garam dengan mengurangi pencemaran mikroplastik di perairan dan memperbaiki teknologi produksi garam.Title: Microplastic Contamination of Boiled Salted Fish and Its Potential Hazards to Human Health, Case Study in BogorThe high accumulation of plastic waste in Indonesian waters can increase the potential contamination of microplastic. Fish and salt are the primary raw materials for boiled salted fish, both of which can carry various contaminants, including microplastics. The objective of this study was to determine the presence of microplastic contamination in boiled salted fish produced by five processors in Tanah Sareal, North Bogor, Parung, and Ciampea. The microplastic content was analyzed from 5 types of fish, namely milkfish (Chanos chanos), mackerel tuna (Euthynnus affinis), indian scad (Decapterus russelli), moon fish (Mene maculata), and indian mackerel (Rastrelliger kanagurta), each of fresh fish and its boiled salted product, salt used, and boiled water. Microplastic identification was carried out microscopically on samples prepared by H2O2 destruction and further confirmed by FTIR-UATR. The results showed that the amount of microplastics in the products ranged from 0.22±0.15 to 0.69±0.12 MP/g or an increase of about 11-19% compared to the raw material. A total of 0.17±0.02 MP/g was found in the salt sample and 0.10±0.02 MP/mL in the boiling water sample. FTIR-UATR analysis showed that the dominant microplastic was polypropylene (PP) as much as 54% in fragments or film form, and polyethylene (PE) account for 46% in the form of fibers/fragments. The estimated exposure of microplastics due to consuming boiled salted fish based on the level of consumption of boiled salted fish in Indonesia is 2,345±603 MP/person/year. This condition indicates a potential danger if boiled salted fish is consumed at a large amount and continuously because of the cumulative nature of microplastics. So it is necessary to reduce the amount of microplastic content in the fish material and salt by reducing microplastic pollution in the waters and improving the salt production technology.
