Abstract

Plastics become debris in the ocean that can be broken down into tiny particles of micro size (<5 mm) and scattered into columns to the bottom of the water. Its very small size makes it easily accessible to various aquatic organisms, such as plankton, crustacean, and mussel. There have been many studies use mussel as a bioindicator for microplastic pollution but no one has observed the effect of microplastic exposure to mussel mortality. The aim of study was to examine the effect of microplastic on mussel mortality. Green mussels were collected from Mandalle Waters, Pangkep Regency (Pangkajene Kepualauan) then were exposed to microplastic polyethylene originating from shieving of scrub soap. The exposure was carried out for 7 days with microplastic concentrations of 0.05 (A), 0.5 (B), and 5 (C) g/L. Statistical test results showed the treatment B and C were not significantly different, but the two treatment were significantly different from treatment A. The percentage of green mussel mortality during the experiment increased with increasing microplastic concentrations with the percentage of mortality exceeding 80% at treatment C.

Abstract

Study on several metals in Lake Hasanuddin University (Unhas) has been conducted as a basis of management of the lake as an aquaculture activity. This study was performed by sampling of water, sediment and biota, such as fish.  The results revealed that the average of temperature 32.72 oC has exceeded the threshold of the quality standard.  The average of dissolved oxygen, ammonia, pH were 5.8 mg/l, 0.016 mg/l, and 7.72 respectively.  Consentrations of nitrate and phosphate were 0.39 and 0.28 mg / l, respectively. Concentrations of mercury (Hg), cadmium (Cd) and cobalts (Co) were not detected in water coloumn.  Arsenic (As) was detected in level that still allowed by the threshold of the quality standard.  Concentrations of chromium (Cr) and plumbum (Pb) have exceeded the threshold of the quality standard.  In sediment, Hg and As were not detected, but Cr was detected in level that not exceed the the threshold of the quality standard.  Conccentrations of Cd, Co and Pb detected exceed the threshold of the quality standard.  Silver barb (Barbonymus gonionotus) that live in the lake has been contaminated by As, Cd and Pb. Keywords: Lake Unhas, metals, aquaculture, Silver barb.

Abstract

Seaweed is one of the leading fishery commodities in the coastal areas of South Sulawesi, with high economic potential. However, its utilization is still predominantly limited to the sale of raw products, resulting in limited economic value added for local communities. This Community Service Program was conducted to promote seaweed product diversification through the development of value-added food products, namely seaweed-based noodles and nuggets. The activity was carried out on May 10, 2025, in Borongkalukua Hamlet, Borimasunggu Village, Maros Baru District, Maros Regency, involving coastal communities as the main participants. The implementation methods included educational sessions, demonstrations and hands-on processing practices, as well as product packaging training. Evaluation was conducted using pretest and posttest approaches to describe changes in participants' responses regarding their knowledge, technical understanding of processing, and motivation. The results showed an increase in the percentage of positive responses across most measured indicators. Participants' knowledge increased from 5–15% before the training to 60–80% after the training, while motivation increased from 45–65% to 75–93%. Overall, the program indicated an improvement in the community's understanding of utilizing seaweed as a value-added product and increased participants' interest in developing local resource-based economic activities. This program has the potential to support capacity strengthening among coastal communities and promote the more sustainable utilization of marine resources.Rumput laut merupakan komoditas perikanan unggulan di wilayah pesisir Sulawesi Selatan yang memiliki potensi ekonomi tinggi, namun pemanfaatannya masih didominasi oleh penjualan dalam bentuk mentah sehingga nilai tambah ekonomi yang diperoleh masyarakat masih terbatas. Kegiatan Pengabdian kepada Masyarakat ini dilaksanakan sebagai upaya mendorong diversifikasi produk rumput laut melalui pengolahan menjadi produk pangan bernilai tambah berupa mie dan nugget. Kegiatan berlangsung pada tanggal 10 Mei 2025 di Dusun Borongkalukua, Desa Borimasunggu, Kecamatan Maros Baru, Kabupaten Maros, dengan melibatkan masyarakat pesisir sebagai peserta utama. Metode pelaksanaan meliputi penyuluhan, demonstrasi dan praktik langsung pengolahan, serta pelatihan pengemasan produk. Evaluasi dilakukan menggunakan pretest dan posttest untuk menggambarkan perubahan respons peserta pada aspek pengetahuan, pemahaman teknis pengolahan, dan motivasi. Hasil kegiatan menunjukkan adanya peningkatan persentase respons positif pada sebagian besar indikator yang diukur. Pengetahuan peserta meningkat dari 5–15% sebelum pelatihan menjadi 60–80% setelah pelatihan, sedangkan motivasi meningkat dari 45–65% menjadi 75–93%. Secara umum, kegiatan ini mengindikasikan adanya peningkatan pemahaman masyarakat terhadap pemanfaatan rumput laut menjadi produk bernilai tambah serta meningkatnya ketertarikan peserta untuk mengembangkan aktivitas ekonomi berbasis sumber daya lokal. Program ini berpotensi mendukung penguatan kapasitas masyarakat pesisir dan pemanfaatan sumber daya laut secara lebih berkelanjutan.
