    Threats of Microplastic Pollution on Aquaculture Activities in Indonesia

    Aquaculture is a growing fisheries sector. Along with the growth of aquaculture, water quality problems become one of the main factors that need to be considered, especially related to pollution pressure. Microplastic (MPs) is a pollutant sourced from anthropogenic activities and is currently in the spotlight and has been widely studied in aquatic environments around the world. However, in Indonesia, research related to MP especially in term of aquaculture activities is still lacking. The presence of MP in aquaculture activities can originate from internal sources such as the use of unmaintained aquaculture equipment/facilities and the use of feed contaminated with MP. Then, the external source of MP at the cultivation location can come from water sources that come from an environment that has been previously polluted by MP. Maintenance of aquaculture equipment/facilities, search for alternative feed raw microplastic free materials and protection of the aquatic environment from MPs are some of the ways to reduce the presence of MP in aquaculture sites. The existence of MP in aquaculture activities is related to food safety of aquaculture commodities

    Tujuan dari penelitian ini adalah untuk mengetahui nilai akumulasi logam timbal pada makrozoobenthos, pola persebarannya di Waduk Cirata dan mengetahui peranan makrozoobenthos dalam proses biomagnifikasi yang terjadi     di Waduk Cirata. Metode yang digunakan dalam penelitian ini adalah metode survei. Pengukuran kandungan logam timbal pada sedimen dan makrozoobenthos dengan menggunakan metode AAS (Atomic Absorbtion Spectofotometer). Makrozoobenthos di Waduk Cirata yang teridentifikasi terdiri dari 9 genus yang keseluruhannya tergolong kedalam Filum Moluska dan Kelas Gastropoda. Kepadatan makrozoobenthos paling rendah berada di Stasiun Muara Cibalagung dengan kepadatan 74 individu/m2 dan kelimpahan tertinggi berada pada Stasiun Dam dengan kepadatan 267 individu/m2. Kandungan logam timbal pada makrozoobenthos berkisar antara 0,78 – 3,22 mg/kg, yang secara umum lebih rendah dari kandungan logam timbal pada sedimen yang berkisar antara 0,29 – 5,04 mg/kg sementara kandungan logam timbal pada air pada semua stasiun yaitu <0,01 ppm. Kandungan logam timbal pada sedimen Inlet Muara Citarum menurun secara perlahan hingga pada stasiun Muara Cibalagung, kemudian kembali naik pada stasiun Gandasoli dan Dam. Hal tersebut diduga akibat adanya masukan logam timbal akibat penggunaan pakan pada budidaya KJA di Waduk Cirata. Makrozoobenthos diduga tidak terlalu berperan dalam dalam proses biomagnifikasi di Waduk Cirata

    Attention towards microplastic (MP) pollution in various environments is increasing, but relatively little attention has been given to the freshwater-riverine environment. As the biggest city in the eastern Indonesia region, Makassar can be a potential source of MP pollution to its riverine area. This study aimed to determine the spatial trends, seasonal variation, and characteristics of MPs in the water and sediment of Tallo River, as the main river in Makassar. Water samples were collected using a neuston net and sediment samples were collected using a sediment corer. The samples collected contained MPs with an abundance ranging from 0.74 ± 0.46 to 3.41 ± 0.13 item/m3 and 16.67 ± 20.82 to 150 ± 36.06 item/kg for water and sediment samples, respectively. The microplastic abundance in the Tallo River was higher in the dry season and tended to increase towards the lower river segment. Fragments (47.80–86.03%) and lines (12.50–47.80%) were the predominant shapes, while blue (19.49–46.15%) and transparent (14.29–38.14%) were the most dominant color. Polyethylene and polypropylene were the common MP polymers found in the Tallo river. Actions to prevent MP pollution in the Makassar riverine area are needed before MP pollution becomes more severe in the future

    This proceeding contains articles on the various ideas of the academic community presented at The 3rd International Conference on Community Engagement and Education for Sustainable Development (ICCEESD 2022) organized by the Universitas Gadjah Mada, Indonesia on 7th-8th December 2022.  ICCEESD is a biannual forum for sharing, benchmarking, and discussing HEI’s activities in developing Education for Sustainable Development towards community engagement. Education for Sustainability as a teaching strategy for resolving community challenges through formal, informal, or non-formal education is expected to benefit from various community service best practices by academics, researchers, and students. The 3rd ICCEESD has “Strengthening Education for Sustainability Towards Better Community Engagement” as its theme this year. It is expected that the 3rd ICCEESD will provide a forum for the presenters and participants to exchange best practices, policies, and conceptual implementation of Education for Sustainability towards better community engagement and explore ideas to address community needs.  Conference Title: 3rd International Conference on Community Engagement and Education for Sustainable DevelopmentConference Theme: Strengthening Education for Sustainability Towards Better Community EngagementConference Acronyms: ICCEESD 2022Conference Date: 7th-8th December 2022Conference Location: Grand Rohan Jogja Yogyakarta, IndonesiaConference Organizer: Universitas Gadjah Mada, Indonesi
