This study aims to analyze the effectiveness of coating time with belimbing wuluh (averrhoa blimbi) extract in reducing the heavy metal mercury (Hg) levels in Mozambique tilapia (O.mossambicus). This research employed a Completely Randomized Design (CRD) method where the data were analyzed using variance analysis (ANOVA) and further tested by Duncan's multiple range test. The study was conducted using an experimental approach with two replications at three different locations: downstream (Bolangitang River), midstream (Sonuo Village), and upstream (Ollot Village). The treatments involved different coating times with averrhoa blimbi extract. The treatment levels consisted of four control levels: 5 minutes, 10 minutes, and 15 minutes. The research results demonstrated that a 15-minute coating time with averrhoa blimbi extract significantly reduced mercury levels in Mozambique tilapia in the downstream area of the Bolangitang River, with the highest reduction percentage reaching 63%. Meanwhile, the lowest reduction percentage was observed in the midstream area (Sonuo Village), with a 10-minute coating time resulting in a reduction percentage of 20.01%. Thus, the coating time of averrhoa blimbi extract was 50% effective in reducing heavy metal mercury (Hg) levels. This study contributes significantly to understanding the potential use of natural materials in addressing heavy metal pollution in freshwater ecosystems. It also highlights the relevance of utilizing local materials such as averrhoa blimbi as an alternative in conservation efforts and the protection of the environment and fisheries resources.

Kegiatan pengabdian kepada masyarakat dilakukan di Desa Tabulo Selatan Kabupaten Boalemo Kecamatan Mananggu, Boalemo, Provinsi Gorontalo dengan pertimbangan hasil survey penelitian dan permasalahan penanaman mangrove dan pengembangan pemanfaatan rumput laut. Warga setempat belum memiliki pengetahuan dan pemahaman yang optimal akan pentingnya ekosistem mangrove dan pemanfaatan rumput laut. Kegiatan yang dilakukan pada bulan Oktober tahun 2024 ini bertujuan untuk memberikan pemahaman kepada masyarakat wilayah pesisir Desa Tabulo Selatan dan membantu mereka memaksimalkan potensi sumber daya lokal yang tersedia khususnya mangrove dan rumput laut. Selain itu, kegiatan ini diharapkan dapat meningkatkan pengetahuan masyarakat akan pentingnya fungsi ekosistem mangrove dalam menjaga keberlanjutan ekosistem pesisir, sekaligus memberikan informasi yang relevan bagi pihak-pihak terkait. Kegiatan pengabdian ini dilaksanakan dalam dua tahap, yaitu sosialisasi dan aktivitas penanaman bibit mangrove. Keterlibatan masyarakat dalam konservasi mangrove sangat krusial, terutama dalam menghadapi tantangan perubahan iklim yang berdampak pada kestabilan lingkungan pesisir. Dengan adanya peningkatan permukaan air laut dan frekuensi bencana alam yang lebih tinggi, keberadaan mangrove menjadi semakin krusial. Beberapa komunitas telah memulai inisiatif untuk menanam kembali mangrove, tidak hanya untuk memperbaiki kerusakan yang telah terjadi, tetapi juga untuk meningkatkan kesadaran akan pentingnya ekosistem ini. Kata kunci: Ekosistem, mangrove, Desa Tabulo. ABSTRACT Community service was conducted in South Tabulo Village, Mananggu District, Boalemo Regency, Gorontalo Province, based on the findings of research surveys addressing challenges in mangrove planting and the development of seaweed utilization. The local community has yet to acquire optimal knowledge and understanding of the critical role of mangrove ecosystems and the potential benefits of seaweed. Implemented in October 2024, these activities aimed to enhance the awareness of coastal communities in South Tabulo Village while assisting them in maximizing the sustainable use of local resources, particularly mangroves and seaweed. The initiative also sought to improve public understanding of the ecological functions of mangrove ecosystems in maintaining the sustainability of coastal environments and to provide valuable information for relevant stakeholders. The program was conducted in two phases: socialization and practical mangrove seedling planting. Community participation in mangrove conservation is essential, particularly in addressing the challenges of climate change, which significantly impacts coastal ecosystem stability. With rising sea levels and the increasing frequency of natural disasters, the preservation and restoration of mangroves have become more critical than ever. Several community-driven efforts to replant mangroves have emerged, aiming to mitigate existing environmental damage and foster greater awareness of the indispensable role these ecosystems play in coastal resilience and biodiversity conservation.

The present rescarch aimed to analyze the sensory characteristics and moisture content of smoked skipjack tuna using modern smoking equipment at different smoking times. The research method used was an experimental research method with two replications. Besides, the treatment factor was the length of smoking times which consisted of three levels: one hour, three hours, and five hours. The moisture content test was done through non-factorial completely randomized design analysis and Duncan’s multiple range test, In contrast, the sensory quality test was analyzed descriptively using the Rasch Model method. The findings revealed that different lengths of smoking had a significant effect (p 0,05) on the moisture content of smoked skipjack tuna. Based on the results of the Rasch Model analysis, it was found that the panelis preferred the sensory quality of smoked fish in treatment B (three hours).
