Sedimentation due to the land function shifting in the mangrove area at Inner Ambon Bay has been going on for a long time. This study aims to analyze the changes in substrate characteristics, including the colour and size of sediment particles, and to recommend management directions for the area. This research was conducted in October 2023 in Passo mangrove area in Ambon. Substrate samples were collected from nine stations using the coring method by applying a sediment core 30 cm deep. Stations 1-3 were located near the residential area; stations 4-6 were 50 meters from stations 1-3 towards the forest so were stations 7-9. The samples from each station were divided into three sections per 10 cm depth. The samples were then dried, sieved, and weighed for further analysis. The changes in substrate colour were descriptively described using field documentation, while the particle sizes of sediments were analyzed using the Wentworth Scale. Furthermore, a descriptive qualitative approach was applied to formulate the management directions. The result shows that substrate colour and particle size at stations 1-3 are altered. The colour at Stations 1-3 is different from other stations, which is light brown, while the others are black. The particle size dominated at Stations 1-6 is fine sand (0.025 mm), whereas the substrates at Stations 7-9 are dominated by silt (0.06 mm). Considering the high activities of land function shifting in Passo and Lateri Villages, the alteration will continue significantly. Therefore, four directions to manage the area are defined as follows: 1) the regulation regarding 30% of the land area assigned for green open space must be obeyed; 2) terrestrial vegetation planting for erosion control; 3) mangroves planting; and 4) continual research for monitoring and evaluation purpose. ABSTRAK Permasalahan sedimentasi akibat alih fungsi lahan atas untuk pemukiman di kawasan mangrove Teluk Ambon Dalam telah berlangsung dalam kurun waktu yang panjang. Penelitian ini bertujuan untuk menganalisis perubahan karakteristik substrat meliputi warna dan ukuran partikel sedimen, serta merekomendasikan arahan pengelolaan pada kawasan hutan mangrove Desa Passo. Penelitian ini dilakukan pada bulan Oktober 2023 di kawasan mangrove Desa Passo, Kota Ambon. Sampel substrat diambil pada sembilan stasiun dengan metode coring menggunakan sedimen core sederhana hingga kedalaman 30 cm. Stasiun 1-3 berada di dekat pemukiman, stasiun 4-6 berada sejauh 50 m dari stasiun 1-3 ke arah mangrove, sama halnya dengan stasiun 7-9. Sampel substrat yang diperoleh dibagi menjadi tiga bagian menurut kedalaman masing-masing berukuran 10 cm. Sampel substrat dikeringkan kemudian diayak dan ditimbang untuk dianalisa lebih lanjut. Perubahan warna substrat akan dianalisis secara deskriptif berdasarkan dokumentasi lapangan, sedangkan ukuran partikel sedimen dianalisis dengan menggunakan Skala Wentworth. Arahan pengelolaan dianalisis secara deskriptif kualitatif. Hasil penelitian menunjukan pada stasiun 1-3 telah terjadi perubahan substrat meliputi warna dan ukuran partikel, dibandingkan stasiun lainnya. Warna susbtrat pada stasiun 1-3 cenderung coklat muda, sedangkan stasiun lainnya berwarna hitam. Ukuran partikel sedimen yang mendominasi stasiun 1-3 juga stasiun 4-6 adalah pasir halus (0,025 mm), sedangkan stasiun 7-9 didominasi oleh lumpur (0,063 mm). Mengingat tingginya aktivitas pembukaan lahan untuk pemukiman di daerah Desa Passo dan Lateri, maka perubahan substrat akan terus terjadi secara signifikan. Terdapat empat arahan pengelolaan yaitu: 1) persentase ruang terbuka hijau sebesar 30% harus dipatuhi; 2) penanaman vegetasi penahan erosi di lahan atas; 3) penanaman mangrove; dan 4) melakukan penelitian sebagai upaya monitoring evaluasi.

Marine debris is a pollution problem that has occurred everywhere, even in the waters of remote areas. Marine debris pollution has been detected from ocean waters to bay waters. The waters of Ambon Bay as part of the sea as a whole have also been polluted by marine debris. This is evidenced by the presence of debris stranded on the coast of Hative Besar. This research was conducted with the aim of knowing the composition of the type and density of debris stranded on the coast of Hative Besar. Sampling was carried out using the transect method. The results showed that there were eight types of waste, namely plastic, glass and ceramics, cloth, metal, paper, rubber, wood, and medical object. Plastic is the debris with the highest type composition, both on the coast of Wailaa at 90% and Batu Lobang at 89%. The density of plastic debris at the Wailaa area is 50 items/m2, while the Batu Lobang area is 44.91 items/m2. In addition, as a result of the pandemic that occurred, medical object was found, namely masks. The high level of plastic debris in Ambon Bay waters needs to be an important concern because this type of plastic waste is difficult to decompose and the residence time in the environment reaches hundreds of years. The existence of plastic debris is a threat to marine resources in Ambon Bay waters. ABSTRAK Sampah laut merupakan masalah pencemaran yang telah banyak terjadi dimana-mana, bahkan sampai pada perairan daerah terpencil. Pencemaran sampah laut telah terdeteksi dari perairan samudera hingga perairan teluk. Perairan Teluk Ambon sebagai bagian dari laut secara keseluruhan juga telah tercemar sampah laut. Hal ini terbukti dengan adanya sampah yang terdampar di pesisir pantai Hative Besar. Penelitian ini dilakukan dengan tujuan untuk mengetahui komposisi jenis serta kepadatan sampah yang terdampar di pesisir pantai Hative Besar. Pengambilan sampel dilakukan dengan menggunakan metode transek. Hasil penelitian menunjukan terdapat delapan jenis sampah yaitu plastik, beling dan keramik, kain, logam, kertas, karet, kayu, dan medis.

The ice-ice disease that attacks seaweed thalli inhibits growth and can lead to crop failure. This study aimed to analyze the effect of freshwater immersion in preventing the spread of ice-ice disease, which can disrupt seaweed growth. The research was conducted from August to October 2023 at the Marine Aquaculture Center of Ambon. An experimental laboratory method was applied in this study. The seaweed samples were obtained from the waters of Seira, Tanimbar Islands Regency, Maluku. Freshwater immersion treatments were applied for 3 minutes, 5 minutes, 7 minutes, and 9 minutes, along with a control. Each treatment was replicated three times to obtain the average growth values of the seaweed. Growth observations were conducted over a period of six weeks. The results showed that the average seaweed growth tended to decrease during the first and second weeks. This decrease was attributed to the breakage of many seaweed thalli, presumably due to adaptation to new environmental conditions. The daily growth rate of seaweed subjected to a 9-minute freshwater immersion showed a positive value of 0.29 g/day, and the control treatment of 0.16 g/day. The weekly SGR showed negative values for the 3-minute (-2.16%), 5-minute (-1.27%), and 7-minute (-6.38%) immersion treatments. In contrast, the 9-minute immersion treatment showed positive values for both daily and weekly growth rates, amounting to 0.34% and 2.38%, respectively. Statistical analysis revealed that the duration of freshwater immersion did not result in a significant difference, indicating that freshwater immersion duration had no significant effect on seaweed growth. ABSTRAK Penyakit ice-ice yang menyerang thallus rumput laut menghambat pertumbuhan serta mengakibatkan gagal panen. Tujuan penelitian ini adalah untuk menganalisis pengaruh perendaman air tawar untuk mencegah penyebaran penyakit ice-ice yang dapat mengganggu pertumbuhan rumput laut. Penelitian ini dilakukan pada bulan Agustus-Oktober 2023 di Balai Perikanan Budidaya Laut Ambon. Metode yang digunakan pada penelitian ini yaitu metode eksperimen di laboratorium. Rumput laut diperoleh berasal dari perairan Seira, Kabupaten Kepulauan Tanimbar, Maluku. Lama perendaman air tawar dilakukan selama 3 menit, 5 menit, 7 menit dan 9 menit serta kontrol. Masing-masing perlakuan dilakukan pengulangan sebanyak 3 kali sehingga diperoleh nilai rata-rata pertumbuhan rumput laut. Pengamatan pertumbuhan rumput laut dilakukan selama 6 minggu. Hasil penelitian menujukan rata-rata pertumbuhan rumput laut cenderung mengalami penurunan pada minggu ke-1 dan ke-2. Hal ini disebabkan banyaknya thallus rumput laut yang patah, diduga akibat adaptasi dengan kondisi perairan baru. Laju pertumbuhan harian rumput laut dengan lama perendaman 9 menit menunjukan nilai positif 0,29 gr/hari dan kontrol sebesar 0,16 gr/hari. Nilai SGR per minggu menunjukan nilai negatif pada lama perendaman 3 menit, 5 menit dan 7 menit masing-masing -2,16%, -1,27%, dan -6,38%. Sedangkan pada lama perendaman 9 menit menunjukan nilai positif baik untuk harian maupun mingguan masing-masing sebesar 0,34% dan 2,38%. Hasil analisa statistik menunjukan lama perendaman air tawar tidak berbeda nyata, artinya tidak memberikan pengaruh terhadap pertumbuhan rumput laut.
