Abstract

Pulau Ambon memiliki dinamika oseanografi dan morfodinamik yang kompleks yang memengaruhi pencampuran massa air, transportasi sedimen, serta variabilitas klorofil-a dan Total Suspended Solid. Penelitian ini bertujuan untuk memetakan dan menganalisis sebaran klorofil-a dan Total Suspended Solid (TSS) di perairan pesisir utara Pulau Ambon menggunakan citra satelit Landsat 9. Proses pengolahan data meliputi koreksi geometrik, koreksi radiometrik, konversi reflektan Top of Atmosphere (ToA), serta penerapan algoritma estimasi klorofil-a dan TSS. Hasil pemetaan menunjukkan bahwa konsentrasi klorofil-a lebih tinggi pada zona pesisir (0.198–0.265 mg/L) dan menurun ke arah laut terbuka (0.127–0.162 mg/L), menandakan tingginya masukan nutrien dari daratan dan karakter perairan oligotrofik di laut lepas. Sebaran TSS juga memperlihatkan nilai tinggi di sepanjang garis pantai (10.21–20.62 mg/L) akibat limpasan daratan, erosi, dan aktivitas manusia, sedangkan perairan yang lebih jauh menunjukkan nilai lebih rendah (10–14 mg/L). Analisis berbasis penginderaan jauh ini memberikan informasi penting bagi pengelolaan kualitas perairan dan perencanaan pengelolaan wilayah pesisir secara berkelanjutan.

Abstract

This Community Service activity aims to improve the understanding of Rehoboth Christian Middle School students in Ambon regarding marine debris, its sources, and its impact on marine organisms through an interactive educational approach. Ambon Bay, as a semi-enclosed body of water, faces a serious problem in the form of accumulated plastic waste, most of which originates from land-based activities. The activity was carried out through a presentation-based socialization, pre-test, discussion, and post-test. The evaluation results showed a significant increase in three main aspects: understanding marine debris, waste sources, and how to reduce it, from 53–63% in the pre-test to 100% in the post-test. The material provided emphasized the local context of Ambon Bay, including waste sources, its ecological impact on biota, and prevention efforts in the school environment. This activity succeeded in raising ecological awareness and encouraging concrete actions such as sorting waste, reducing single-use plastics, and maintaining a clean environment. This program has proven effective in fostering environmental awareness from an early age.

Abstract

The potential of marine resources from the Banda Sea, particularly the waters of Nusa Laut, represents an important economic aspect for local fishers. Several fishing fleets targeting scad, including mini purse seine vessels, are widely distributed in the area, with continuous exploitation activities occurring every week. This study aimed to analyze the growth pattern, mortality, and sex ratio of white scad (Decapterus macrosoma) in Nusa Laut waters, landed at Arumbai Market, Ambon. The research was conducted using a survey method from January to June 2025, with a total sample of 150 individuals. Data were analyzed based on growth pattern, fish mortality, and sex ratio analyses. The results showed that the asymptotic length (L∞) was estimated at 24.7 cm total length (TL), with a growth coefficient (K) of 0.61 year⁻¹ and a theoretical age at zero length (t₀) of −0.25 year. The fishing mortality (F) value was 0.46 year⁻¹, the total mortality (Z) was 1.80 year⁻¹, and the natural mortality (M) was 1.34 year⁻¹, resulting in an exploitation rate (E) of 0.25. The sex ratio analysis conducted from February to June indicated that the proportion of male and female fish was in a balanced condition, with a ratio of 1:1. Based on the exploitation analysis, the length corresponding to half of the asymptotic length (L∞/2 = 12.35 cm TL) indicated that the captured fish were still relatively small. Therefore, the biological characteristics of white scad caught in Nusa Laut waters, Central Maluku, and landed at Arumbai Market, Ambon City, indicate that the fish are predominantly captured at a small size with a relatively low exploitation level.
