Abstract

Seagrass is a high-level flowering plant (angiospermae) that lives in shallow waters up to a depth of 50-60 meters and can even reach a depth of 90 meters, with the highest abundance in the tidal zone. Tapadaa Village, located in Botumoito District, Boalemo Regency, is a coastal area with high seagrass ecosystem potential. Local people use seagrass beds for various economic activities such as collecting gastropods (snails) and sea cucumbers, fishing, and as a boat mooring area. However, these activities can potentially threaten seagrass's survival in the area. This study aims to identify the types of seagrasses and calculate their composition and density in the waters of Tomini Bay, Tapadaa Village. The study was conducted in May 2024 using a 50x50 cm quadrant method. The data collected includes species composition and seagrass density. The results of the study showed that there were nine types of seagrasses in the waters of Tomini Bay, Tapadaa Village, namely Cymodocea rotundata, Cymodocea serrulata, Enhalus acoroides, Halodule pinifolia, Halodule uninervis, Halophila ovalis, Syringodium isoetifolium, Thalasia hemprichi, and Thalassodendron ciliatum. The most dominant species was Halodule pinifolia (37.18%), followed by Cymodocea rotundata (30.06%). Meanwhile, the species with the lowest composition was Enhalus acoroides (0.14%). The total density of seagrass reached 5.403.16 ind/m². These findings are expected to provide vital information for conservation efforts and management of seagrass ecosystems in the area.

Abstract

The waste management training program for paving block production in Laut Biru Village aims to enhance community awareness and skills in sustainable plastic waste management. This program focused on transforming plastic waste into paving blocks as a waste management solution and an effort to support a circular economy. The methodology included observational surveys, program formulation through Focus Group Discussions (FGD), training implementation, as well as evaluation and monitoring. The initial results demonstrated an increase in community awareness of integrated waste management and environmental sustainability. Evaluations showed that 61.54% of the participants recognized paving block technology as a viable waste solution, while 84.62% showed improved awareness of the dangers of plastic waste. This initial success highlights the significant potential of reducing plastic waste and improving community economic welfare. Further recommendations include capacity enhancement, integration with BUMDes, and government policy support. Collaboration with local organizations can expand the impact of the program and establish a more effective waste management system. With the strategic implementation of these measures, Laut Biru Village has the potential to become a model for integrated waste management in other coastal villages.

Abstract

The Bone River faces potential pollution due to human activities around it. To ensure this, macrozoobentos are used as bioindicators by utilizing the characteristics of their constituent communities that exhibit sedentary behavior, limited mobility, and sensitivity to aquatic conditions. This study aims to examine the abundance and diversity of macrozoobentos in the Bone River and Bolango River, Gorontalo Province. The research was conducted from May to August 2023 at several observation stations on both rivers. The identification results showed a total of 127 macrozoobentos individuals consisting of 72 individuals in the Bone River and 55 individuals in the Bolango River, with the dominance of the Baetidae (PlatyBaetis) and Hydropsychidae (Cheumatopsyche and Hydropsyche) families that are widespread in both locations. A low dominance index indicates the absence of a single species that dominates significantly, while the fairly diverse distribution of taxa reflects relatively good water quality conditions in both rivers. These findings serve as an important basis for the sustainable monitoring and management of aquatic resources in the region.

Abstract

Fase bulan merupakan faktor lingkungan alami yang memengaruhi distribusi ikan di perairan secara spasial dan temporal. Penelitian ini bertujuan untuk membandingkan komposisi dan kelimpahan ikan gobi di Sungai Bone Provinsi Gorontalo pada fase bulan gelap dan terang. Pengambilan sampel dilakukan di tiga stasiun sepanjang Sungai Bone Provinsi Gorontalo pada pukul 08.00 hingga 15.00 WITA. Waktu pengambilan sampel dilakukan pada fase bulan gelap dan terang masing-masing pada 1 Dzulhijjah 1446 Hijriyah (bulan gelap) dan pada 13 Dzulhijjah 1446 Hijriyah (bulan terang). Hasil identifikasi menunjukkan terdapat 9 spesies ikan gobi pada bulan terang dan 8 spesies pada bulan gelap, dengan Sicyopterus longifilis sebagai spesies dominan. Hal ini mengindikasikan bahwa komposisi dan kelimpahan ikan gobi di Sungai Bone Gorontalo dapat saja dipengaruhi oleh fase blulan. Namun berdasarkan uji korelasi non parametrik Spearman, tidak terdapat hubungan antara fase bulan dengan jumlah individu maupun kelimpahan relatif ikan gobi di Sungai Bone

Abstract

This study aims to assess the diversity, evenness, and dominance of gastropods in dead coral habitats, as well as the current environmental condition of the waters around Lahe Island, Pohuwato Regency. The research was conducted in April 2025. Gastropod sampling was carried out using the hand-picking technique during low tide conditions, employing a belt transect method measuring 50 × 3 meters across three observation stations. Water quality parameters were measured during the early stages of tidal retreat. Based on the results, gastropod species composition consisted of 34 species, 185 individuals, and 12 families (Buccinidae, Columbellidae, Conidae, Cypraeidae, Mitridae, Muricidae, Nassariidae, Pisaniidae, Strombidae, Tegulidae, and Turbinidae). The Shannon diversity index (H’) at all observation stations was < 2, indicating low diversity. The Simpson dominance index (D) at all stations was < 1, suggesting a high level of dominance. The evenness index (Ep) showed values approaching 0, indicating low species evenness. The water conditions around Lahe Island, Pohuwato Regency, indicate a moderate level of pollution based on the Shannon diversity index (H’), yet still support the survival of marine biota.
