Abstract

ABSTRAKPencemaran laut oleh plastik saat ini menjadi ancaman penting karena meningkat secara signifikan hingga mencapai 47-85% setiap tahunnya. Sampah plastik dapat terfragmentasi menjadi lebih kecil atau disebut mikroplastik yang mempunyai ukuran 5 mm. Permasalahan mikroplastik juga banyak ditemukan di Indonesia, salah satunya adalah perairan Teluk Jakarta sebagai sumber perikanan demersal. Jenis ikan demersal yang mempunyai nilai ekonomi tinggi antara lain ikan kakaktua anglu (Chlorurus sordidus) yang merupakan ikan herbivora dan ikan kurisi sirip pucat (Nemipterus thosaporni) yang merupakan ikan omnivora. Tujuan penelitian ini adalah untuk mengidentifikasi karakteristik mikroplastik pada insang, gastrointestinal, dan daging pada dua ikan tersebut. Karakteristik mikroplastik diamati menggunakan mikroskop stereo dengan bantuan OptiLab. Kelimpahan mikroplastik pada 10 ekor ikan kakatua anglu sebesar 132,75 partikel/gram pada insang, 146,4 partikel/gram pada gastrointestinal, dan 32,2 partikel/gram pada daging. Pada 10 ekor ikan kurisi sirip pucat terdapat 120,5 partikel mikroplastik/gram pada insang, 219,75 partikel/gram pada gastrointestinal, dan 27,7 partikel/gram pada daging. Bentuk yang dominan pada ketiga organ dari kedua jenis ikan adalah bentuk fragmen dan warna yang dominan adalah hitam.Kata Kunci: Daging, Insang, Gastrointestinal, Mikroplastik, Teluk JakartaABSTRACTPollution in the sea by plastic is currently an important threat because it has increased significantly to reach 47-85% each year. Plastic waste can be fragmented into smaller pieces or called microplastics which have a size of 5 mm. Microplastic problems are also found in Indonesia, one of which is the Jakarta Bay waters as a source of demersal fishery. Demersal fish species that have high economic value include the anglu parrotfish (Chlorurus sordidus) which is a herbivorous fish and the palefin bream fish (Nemipterus thosaporni) which is an omnivore fish. The purpose of this study was to identify the characteristics of microplastics in the gills, gastrointestinal, and flesh in different two species. The characteristics of microplastics were observed using a stereo microscope with the help of OptiLab. The abundance of microplastics in 10 anglu parrot fish was 132,75 particles/gram in the gills, 146,4 particles/gram in the gastrointestinal, and 32,2 particles/gram in the flesh. In 10 palefin bream fish, there were 120,5 microplastic particles/gram in the gills, 219,75 particles/gram in the gastrointestinal, and 27,7 particles/gram in the flesh. The dominant shape of the three organs of both species of fish is the fragment shape and the dominant color is black.Key words: Flesh, Gastrointestinal, Gill, Jakarta Bay, Microplastics

Abstract

Mojoroto, as the most populated sub-district in Kediri, has a waste generation rate of 0.66 kg/person/day. This sub-district owns 26 waste bank units across 14 urban villages and actively buys and sells waste. The purpose of community service is to innovate in managing waste recycling in Kediri City by utilizing a digital waste recycling application called Apps4SWAM. Changing to a digital system is expected to simplify the waste recycling process and increase system transparency. The actors involved in this activity are customers and waste bank managers. Six active waste banks in the Mojoroto Sub-district participated in this community service activity. The Apps4SWAM application was developed based on input from all stakeholders who use the application. This application was socialized to the community, especially waste bank customers. A survey was also conducted to determine the community's willingness to manage waste and use this application. Two hundred respondents, consisting of waste bank customers and non-waste bank customers, were surveyed about their waste management behaviour and responses to the waste bank application. The results of this activity show that 80% of waste bank managers use this application to facilitate transactions in the waste bank. Customers also stated that the application system makes recording waste easier and faster, making the financial system more transparent. The increase in waste sales after using the app averaged 153%, and the total number of waste bank customers using the app reached 250. However, obstacles are still faced, ensuring all stakeholders involved in recycling in Kediri can fully switch to using the app for waste recycling activities. The government's readiness to continue this program also needs to be considered, while support from other stakeholders such as collectors and industries is also key. This app can potentially form a waste management network, especially in terms of recycling, in Kediri City.
