This study presents a comprehensive checklist of sea cucumber species found in Biluhu Timur waters, Tomini Bay, Gorontalo, Indonesia, across the new moon and full moon lunar phases. The survey identified eight species across five genera, including Actinopyga miliaris, A. mauritiana, Holothuria scabra, and H. leucospilota, noting significant distribution patterns influenced by lunar cycles and different biomes at three stations. Actinopyga miliaris and A. mauritiana, both classified as Vulnerable, were more active in the seagrass biome of Station I during the full moon. H. leucospilota, classified as Least Concern, was highly prevalent in the sandy substrate biome of Station II during the new moon, indicating a strong ecological association with that habitat. Stichopus horrens, classified as Data Deficient, showed notable activity in the coral reef biome of Station III. Environmental parameters such as water temperature, salinity, and pH were measured at each station to understand the conditions influencing these species. This study highlights the importance of lunar phases, biomes, and environmental variables on sea cucumber distribution. The findings underscore the need for conservation efforts that consider these factors to protect species vulnerable to overfishing and habitat degradation. Further research should include genetic analysis and expanded temporal and spatial scales to develop effective conservation strategies and sustainable management practices

Activities around Bone River, one of the largest rivers in Gorontalo Province, include agriculture, settlement, gold mining, sand excavation, industry, and illegal logging. This research aimed to report the water quality status of Bone River using the STORET method as an index commonly used for measuring pollution levels in a water body, which the Indonesian government regulates, as stated in the Decree of the Minister of Environment, No. 115, 2003. This work involved data from 2021-2023 along the upstream to downstream of the river. There were 12 water quality parameters measured: temperature, TSS, DO, pH, COD, BOD, nitrate, phosphate, ammonia, and the heavy metals (Pb, Cd, and Hg) concentration. This study revealed that parameters met water quality standards for class I and class II: temperature, pH, DO, Pb, and Cd. The index scores ranged from -96 to 0. The upstream area was categorized as good, and the midstream to downstream was recognized as heavily polluted. This pollution level is dominated by organic waste from agricultural and domestic household activities. The concentration value consistently exceeds the quality standard in all data from St 5 to St 12. These two parameters are enough to significantly cause worsening water quality based on the STORET with a total score contribution of -40. BOD and COD parameters contribute the most to the river pollution level.Keywords:Water qualityPollutionSTORETBone River

Latar belakang: Sungai merupakan ekosistem perairan yang penting dalam siklus hidrologi, berfungsi sebagai daerah resapan air bagi lingkungannya. Habitat fisik dan kondisi kesehatan perairan sungai sangat dipengaruhi aktivitas antropogenik serta karakteristik lingkungan sekitar. Sungai Bone yang menjadi pusat aktivitas masyarakat di Gorontalo sangat rentan terhadap pencemaran. Makroinvertebrata potensial dijadikan sebagai alat pemantauan pencemaran di sungai karena karakteristik komunitas penyusunnya, yang ditandai dengan perilaku menetap, mobilitas terbatas, dan sensitif terhadap kondisi perairan. Penelitian ini bertujuan untuk menilai kualitas perairan Sungai Bone berdasarkan kondisi habitat fisik dan keanekaragaman makroinvertebrata.Metode: Penilaian terhadap kondisi habitat fisik dan kualitas perairan dilakukan pada 12 stasiun pengamatan yang mewakili aliran utama hulu-hilir Sungai Bone. Penentuan kondisi habitat fisik sungai didasarkan pada pemeriksaan dan penilaian terhadap kriteria tingkat kesehatan habitat sungai dimana parameter yang diamati berupa indikator karakteristik substrat dasar, indikator faktor gangguan, parameter fisika-kimia air. Struktur komunitas makroinvertebrata dianalisis melalui perhitungan keragaman famili makrozoobentos secara keseluruhan, persentase kelimpahan EPT, nilai indeks keanekaragaman (H’), dominasi (D’) serta keseragaman (E’). Penentuan kualitas perairan dilakukan berdasarkan pendekatan Biotilik.Hasil: Hasil penelitian ini mengungkapkan variasi spasial dalam komunitas makroinvertebrata, parameter kualitas air (terutama BOD, COD). Semakin ke hilir kondisi habitat fisik, dan kualitas perairan Sungai Bone cenderung mengalami penurunan.Simpulan: Kualitas perairan Sungai Bone berdasarkan hasil penelitian terbagi menjadi tiga kategori kelompok tercemar yaitu tidak tercemar-sehat (bagian hulu), tercemar ringan-kurang sehat (bagian tengah), dan tercemar ringan-tidak sehat (bagian hilir). Kondisi tercemar di Sungai Bone, terutama di bagian tengah hingga hilir, kemungkinan besar disebabkan oleh pencemaran yang berasal dari aktivitas antropogenik masyarakat. ABSTRACT Title: Physical Habitat Conditions and Macroinvertebrate Diversity as Indicators of Pollution in the Bone River, GorontaloBackground: Rivers are water ecosystems that are important in the hydrological cycle, functioning as water catchment areas for the environment. Anthropogenic activities and the characteristics of the surrounding environment greatly influence the physical habitat and health conditions of river waters. The Bone River, which is the center of community activity in Gorontalo, is very vulnerable to pollution. Macroinvertebrates have the potential to be used as a tool for monitoring pollution in rivers because of the characteristics of their constituent communities, which are characterized by sedentary behavior, limited mobility, and sensitivity to water conditions. This research aims to assess the water quality of the Bone River based on physical habitat conditions and macroinvertebrate diversity.Method: Assessment of physical habitat conditions and water quality was carried out at 12 observation stations representing the main upstream and downstream streams of the Bone River. The evaluation of the river's physical habitat condition was based on the examination and assessment of criteria related to river habitat health, with observed parameters including substrate characteristics, disturbance indicators, and physicochemical water parameters. The structure of the macroinvertebrate community was analyzed by calculating the overall diversity of macrozoobenthos families, the percentage of EPT (Ephemeroptera, Plecoptera, Trichoptera) abundance, and indices of diversity (H’), dominance (D’), and evenness (E’). The water quality assessment was conducted using the Biotilik approach.Result: The results of this study revealed spatial variations in macroinvertebrate communities, water quality parameters (especially BOD, COD). The further downstream the physical habitat conditions, the water quality of the Bone River tends to decline.Conclusion: Based on research results, the water quality of the Bone River is divided into three categories of polluted groups: not polluted-healthy (upstream part), lightly polluted-unhealthy (middle part), and lightly polluted-unhealthy (downstream part). The polluted conditions in the Bone River, especially in the middle to downstream parts, are most likely caused by pollution originating from the community's anthropogenic activities.

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.
