Gastropoda memiliki peranan penting dalam rantai makanan di ekosistem laut. Penelitian ini dilakukan dengan tujuan untuk mengalanisa keanekaragaman spesies gastropoda pada zona intertidal Negeri Tial, Maluku Tengah. Penelitian dilakukan pada bulan Maret 2023, dengan menggunakan metode transek garis. Data gastropoda dikoleksi pada 11 transek. Sebanyak 22 spesies gastropoda ditemukan dalam penelitian ini dan dikelompokan dalam 17 genera, 12 famili dan 6 ordo. Spesies Tenguella granulata memiliki kepadatan dan kemimpahan tertinggi (masing- masing 0,75 ind/m2 dan 13176 individu) Morula uva, Cypraea tigris, dan Mauritia arabica memiliki kepadatan dan kelimpahan terendah. Nilai indeks keragaman spesies gastropoda termasuk kategori sedang, indeks kerserasian spesies berada dalam kategori stabil dan indeks dominasi spesies gastropoda termasuk dalam kategori rendah. Hasil penelitian ini menyediakan data tentang daftar spesies gastropoda pada perairan negeri Tial.

It is important to maintain a healthy marine ecosystem to support eco-friendly and sustainable fishery development. Implementation of Ocean Health Index (OHI) started globally in 2012, and it has been strongly recommended to be conducted at all levels: locally, nationally, and regionally. Indonesia has modified OHI for its national assessment, which its called Indeks Kesehatan Laut Indonesia (IKLI). IKLI has been estimated since 2020 and introduction applied at the sub-national level. This study is an attempt to implement IKLI in Maluku province with the main objective is to estimate score of a partial IKLI, based on clean waters (goal no. 9) and biodiversity (goal no. 10). Samples were taken from Ambon and Baguala Bays between June and September 2022. For clean water goals, the parameters used were concentration of phosphate, nitrate, silicate, dissolved oxygen (DO), pH, and the number of ports that implemented green principles. The parameters of water quality of silicate, DO and pH in those two bays are within the range of government-mandated standards, except for nitrate and phosphate concentrations which are not. For the biodiversity goal, the parameters used are the species composition of mangrove, seagrass, fish, and coral. The IKLI biodiversity score was low due to the high level of human activity pressure at the two selected study sites. This study demonstrates the applicability of the IKLI in a partial analysis, and its usefulness in highlighting existing data and knowledge gaps. The study suggests that a comprehensive IKLI assessment should be conducted in Maluku Province. Meanwhile to improve the national-level IKLI assessment, actions should prioritize improving water quality management, expanding marine protected areas, and monitoring coastal ecosystems, especially those heavily affected by human activities.KeywordsArchipelagonutrientOHIIKLI Maluku

Coral reef fish are a crucial fishery resource in tropical waters, including Maluku. Information regarding the species of coral reef fish caught in the waters of Osi Island, West Seram District, is still limited. This study aimed to identify the coral reef fish species captured in the waters of Osi Island and its surroundings based on their meristic and morphometric characteristics. The research was conducted in December 2024, utilizing 12 fish specimens caught by local fishermen. Species identification was carried out through the observation of meristic and morphometric characters, which were then matched with identification keys and taxonomic literature. The results revealed seven coral reef fish species belonging to five genera: Lutjanus, Pterocaesio, Myripristis, Sargocentron, and Siganus. The species identified included Lutjanus rufolineatus, Lutjanus fulviflamma, Pterocaesio tesselata, Myripristis berndti, Myripristis murdjan, Sargocentron tiereoides, and Siganus fuscescens. Pterocaesio tesselata and Siganus fuscescens were the most commonly found species, with three specimens of each. The meristic and morphometric characteristics of all specimens fell within the ranges described in previous studies for these species. This study contributes additional baseline information on the diversity of coral reef fish in Maluku waters.

Banana is a climacteric fruit that continues to ripen after harvesting, and the ripening process plays a crucial role in determining its market value, taste, and consumer safety. In Tawangmangu, a highland region of Central Java, many banana fruit sellers still employ traditional and unsafe methods for ripening, including the use of non-food-grade chemicals. This community service program aimed to enhance the knowledge and practices of 10 local banana sellers by providing participatory training on natural and safe ripening techniques, with a focus on Ambon bananas (Musa paradisiaca var. sapientum). The training combined theoretical education with hands-on practice in using ethylene-based and hygienic ripening methods. Pre- and post-test evaluations revealed a significant increase in participants’ understanding of postharvest physiology and food safety. Furthermore, 80% of the sellers demonstrated the ability to construct and apply low-cost ripening chambers using local materials, and reported reduced fruit spoilage, improved customer satisfaction, and increased marketability. The program successfully bridged the knowledge gap and introduced a practical, low-resource solution aligned with sustainable development goals. This model has the potential to be replicated in other rural agricultural markets to improve food safety and support local economic empowerment.
