Abstract

Chlorophyll-a in waters is one of the important factors that determines the primary productivity/fertility of waters. Chlorophyll-a measurements can be carried out in two ways, namely conventionally by direct measurements in the field and modernly by using remote sensing technology. The aim of this research is to determine variations in the distribution of chlorophyll-a in the waters of the Ombai Strait. The data used in this research is monthly level 3 climatology data from 2003–2022 from the Aqua-MODIS (Moderate-Resolution Imaging Spectroradiometer) satellite using a remote sensing and geographic information system approach. The results of this research were that the highest chlorophyll-a concentration was found in coastal areas and the lowest concentration was found in offshore waters. According to the monthly distribution of chlorophyll-a, the highest concentration was recorded in July with values ranging from 0.251-10.486 mg/m3 with an average of 0.566 mg/m3 and the lowest concentration was recorded in November with values ranging from 0.158-2.151 with an average of 0.427 mg/m3.

Abstract

Peningkatan produksi perikanan tangkap di Pelabuhan Perikanan Pantai Tenau Kupang dipengaruhi secara signifikan oleh aktivitas produksi perikanan. Namun, peningkatan ini perlu didukung oleh pengelolaan aktivitas dan fasilitas pelabuhan yang optimal. Oleh karena itu, diperlukan analisis strategi yang tepat untuk memastikan manfaat yang maksimal bagi seluruh aspek terkait, baik aktivitas maupun fasilitas pelabuhan. Penelitian ini menggunakan metode deskriptif dengan pendekatan analisis SWOT untuk mendeskripsikan kondisi Pelabuhan Perikanan Pantai Tenau Kupang dan merumuskan strategi yang efektif dalam meningkatkan produksi perikanan tangkap. Berdasarkan hasil penelitian, aktivitas pengelolaan perikanan di Pelabuhan Perikanan Pantai Tenau Kupang, seperti pendaratan ikan, penanganan, dan pemasaran, telah berjalan dengan baik. Namun, beberapa kendala masih ditemui, seperti fasilitas yang rusak dan belum lengkap. Melalui analisis SWOT, strategi S-O (Strength-Opportunity) yang direkomendasikan yaitu peningkatan produksi perikanan tangkap melalui pemanfaatan kapal-kapal besar untuk meningkatkan volume tangkapan, optimalisasi penanganan dan pengolahan ikan melalui kolaborasi dengan perusahaan perikanan, serta perluasan jaringan pemasaran dan distribusi hasil tangkapan guna memenuhi tingginya permintaan pasar. Selain itu, dukungan pemerintah setempat dalam bentuk pelatihan dan penyuluhan bagi nelayan juga diperlukan untuk meningkatkan kapasitas dan keterampilan mereka.

Abstract

A fish collection vessel is a vessel specifically used to transport fish including the process of loading, holding, storing, cooling, and preserving fish on board. This research was conducted at the Mayangan Coastal Fisheries Port (PPP) with the aim of determining the characteristics of the types of fish catches collected at KM. Lautan Berlian-99 which were landed at PPP Mayangan. This research was conducted from September to November 2024 at PPP Mayangan using a qualitative method where data collection in this study was collected through the observation method, namely by directly observing the landing of fish at PPP Mayangan. The identification results showed ten types of fish that were successfully caught by fishermen from various fishing gear including purse seines, bottom longlines and drift nets. The fish were then put into the hold of the collection vessel by the transhipment process to be taken to the port. The measurements to be used are standard length measurements with units of cm. The measurements carried out include total length, half body length, tail length, eye height, body width, head width, and eye width.

Abstract

Around 20% of mangrove forests in Indonesia are in a degraded condition, which has a negative impact on the potential for blue carbon storage. When mangroves are damaged or degraded, carbon stored in the soil and vegetation can be released back into the atmosphere as CO2, ultimately increasing greenhouse gas emissions and exacerbating climate change. Mangrove forests can store up to four times more carbon per hectare, around 8001,200 tons per hectare, than terrestrial tropical forests. This research was conducted in the Wini mangrove forest area, North Central Timor, East Nusa Tenggara (NTT) which directly borders Timor Leste. The determination of the location of the observation station was based on a map of changes in mangrove forest land use obtained from the Geospatial Information Agency. The parameters measured included organic carbon, mangrove area and sediment type. Organic carbon was analyzed using the Loss on Ignition (LOI) method, and sediment grain size was measured using a particle size analyzer. The results of the study showed that the average organic carbon stock in mangrove forests reached 570,600843,600 tons per hectare, with an average change in the area of mangrove forests from 2013 to 2023 of 181.29 hectares and the type of sediment dominated by sandy mud. This change in area is caused by the conversion of mangrove land into ponds, rice fields, and settlements.Keywords:MangroveCarbonSedimentborder Area
