Reef fish data were collected at four reef stations using UVC method. The result showed that there were 192 species of reef fish inhabit coral reef of Hukurila village. Pomacentridae, Labridae and Chaetodontidae have high species richness, while other seven families have low species richness. Relative diversity of reef fish in the study area can be classified in poor to moderate category, and the estimated number of species of reef fish was 369 species. Species diversity of reef fish is high, with low species dominance in the community and species evenness of reef fish in their community is in stable condition.

The existence of inorganic waste in the form of plastic is perilous for marine life. Plastics can be broken into micro size known as microplastics. Microplastic is harmful to marine biota because it can be consumed and entered the digestive tract. The purpose of this study was to identify the presence and types of microplastics in cockles blood clams (Anadara granosa) in Tanjung Tiram, Ambon Bay waters. The research method used field observations and laboratory analysis. The results showed that in cockles, fiber was found as much as 360 particles and 61 particles of fragments. The presence of microplastics that have been consumed by cockle will be harmful marine biota as well as humans who consume the cockles. Plastics that contain harmful chemicals will be absorbed into the body of cockles. Based on the results of the study, it can be concluded that microplastics have been found and consumed by cockles. ABSTRAK Keberadaan sampah anorganik berupa plastik sangat membahayakan bagi kehidupan perairan. Plastik dapat terpecah menjadi ukuran mikro yang dikenal dengan mikroplastik. Keberadaan mikroplastik sangat berbahaya bagi biota perairan karena dapat dikonsumsi dan masuk ke saluran pencernaan. Tujuan dari penelitian ini yaitumengidentifikasi keberadaan dan jenis mikroplastik pada kerang darah (Anadara granosa) di Tanjung Tiram perairan Teluk Ambon. Metode penelitian menggunakan observasi lapangan kemudian analisa laboratorium. Hasil penelitian menunjukkan bahwa pada kerang darah, telah ditemukan mikroplastik dengan jenis fiber sebanyak 360 pratikel dan fragmen sebanyak 61 pratikel. Keberadaan mikroplastik yang telah dikonsumsi oleh kerang darah akan berbahaya bukan hanya bagi biota perairan namun juga bagi manusia yang mengkonsumsi kerang darah tersebut. Plastik yang mengandung bahan kimia berbahaya akan terserap masuk ke dalam tubuh kerang darah. Berdasarkan hasil penelitian dapat disimpulkan bahwa mikroplastik telah berada dan dikonsumsi oleh kerang darah. Kata Kunci: mikroplastik, kerang darah, fiber, fragmen, Tanjung Tiram

This study aims to analyze the weight of waste, recycling potential, and processing of banana peel organic waste into eco enzyme as an effort to control environmental pollution. The research was conducted in August-November 2023 in the Pasar Minggu Beach tourist area, Ambon City. The data collection method used direct observation in the field. Banana peel waste data was collected for 4 days, then weighed for further processing into eco enzyme for 3 months. Waste generation data and recycling potential were calculated using the formula set by the National Standardization Agency. The results showed that the weight of banana peel waste generated was 32.2 kg with 195 visitors. The average waste generation obtained was 0.17 or 0.2 kg/person/day, meaning that every visitor who comes to the tourist attractions produces 0.2 kg of banana peel waste. Banana waste that can be recycled is 30 kg and produces 112.5 l of ready-to-use eco enzyme solution. Processing banana peel organic waste into eco enzyme solution contributes ecologically and economically positively. Keywords: Banana peel; Eco enzyme; Organic waste; Tourism; Waste generation. Abstrak Penelitian ini bertujuan untuk menganalisis berat timbulan, potensi daur ulang, serta pengolahan sampah organik kulit pisang menjadi eco enzyme sebagai upaya pengendalian pencemaran lingkungan. Penelitian dilakukan pada Agustus–November 2023 di kawasan wisata Pantai Pasar Minggu, Kota Ambon. Metode pengambilan data menggunakan metode observasi langsung di lapangan. Pengambilan data sampah kulit pisang dilakukan selama 4 hari, kemudian ditimbang beratnya untuk selanjutnya diolah menjadi eco enzyme selama 3 bulan. Data timbulan sampah dan potensi daur ulang dihitung merujuk pada rumus yang ditetapkan oleh Badan Standarisasi Nasional. Hasil penelitian menunjukan berat sampah kulit pisang yang dihasilkan sebesar 32,2 kg dengan jumlah pengunjung sebanyak 195 orang. Rata-rata timbulan sampah yang diperoleh sebesar 0,17 atau 0,2 kg/org/hr, artinya setiap pengunjung yang datang ke tempat wisata menghasilkan sampah kulit pisang sebesar 0,2 kg. Sampah pisang yang dapat didaur ulang sebesar 30 kg dan menghasilkan larutan eco enzyme siap pakai sebanyak 112,5 l. Pengolahan sampah organik kulit pisang menjadi larutan eco enzyme berkontribusi positif baik secara ekologis maupun ekonomis. Kata Kunci: Kulit pisang; Eco enzyme; Sampah organik; Wisata, Timbulan sampah

The increase in population has an impact on the water quality of several rivers in Ambon City, one of which is Wai Batu Gajah. This study aims to analyze the physical chemical parameters of the waters, describe community activities and management efforts that have been carried out, and recommend management strategies and programs in Wai Batu Gajah. The research was conducted in Wai Batu Gajah, Ambon City in May-June 2023 at 7 observation stations. The physical and chemical parameters measured included odor, color, width, height, substrate type, temperature, TSS, current velocity, pH, DO, BOD, and ammonia. The method of collecting data on physical and chemical parameters was carried out directly in the field, then analyzed in the laboratory of the Maluku Province Health and Calibration Center. Data on community activities were obtained through interviews using questionnaires to 35 respondents. The value of the physical and chemical parameters of the waters was referred to the river quality standards. Strategies and management programs were analyzed using SWOT and TOWS methods. The results showed that at stations 6-7, the color of the water was murky and blackish and caused a pungent odor. The average width and height of the river were 7.82 m and 48.49 cm, respectively. The substrate type of stations 1-6 is dominated by rocky sand while muddy sand at station 7. The average TSS value of 0.0399 mg/l and pH value of 8.65 showed that the value was in accordance with quality standards. DO values for stations 5-7, BOD at stations 6-7, and ammonia values for stations 4-7 do not meet quality standards. Community activities carried out are bathing, washing and disposing of garbage. Management efforts that have been carried out are rainwater harvesting, making biopore holes, waste banks, and river tracing. There are 6 management strategies with 16 programs for water quality management of Wai Batu Gajah.
