Abstract

The fisheries sector is one of the sectors with great potential for the Indonesian economy. East Java has a large fishing enterprise, which is due to the spread of fish landing bases and an active role in promoting local fishing production, one of which is the beach fishing port (PPP) Pondokdadap. The aim of this study is to obtain information on the types and volumes of fish production captured in the PPP Pondokdadap in May and June 2022. The method used by the author in conducting this research is a qualitative-descriptive approach. According to the results of research, during May 2022, the production of fish captured in PPP Pondokdadap amounted to 1,813 tonnes. In June, the capture amounted to 1,605 tonnes. There was a decrease in production volume of 207 tonnes, or about 11%. There are 10 species of fish captured, dominated by tuna

Abstract

The fishing port, which acts as a public agency, provides services and facilitates fishing activities for fishermen. One indicator that the service provided is already optimal is the minimum number of vessels in the process of dismantling fish in the port. The study aims to find out the fishing landing system and the number of ships that landed during the period September–August 2022. The method used is directly through field observations and collecting secondary data to supplement the data obtained. The system applied to each port is different. The port of Pondokdadap applies the queue method as well as the system of nahkoda, where the ship's documents must be submitted and the fisherman's number taken before landing. Boats that want to sell fish to the TPI must be equipped with a catch letter. In the period September–August 2022, the highest number of ships was found in June 2022, with 603. For the smallest number in January 2022, there were 22 ships. Based on the results obtained, it is known that the period of April–September has the highest number, while there is a decrease in the number in October–March. There was an increase in the number of vessels that carried out fishing, which was affected by the fishing season, with the high season in the Eastern season.

Abstract

Mangrove ecosystems are recognized as vital blue carbon reservoirs that contribute significantly to climate regulation through biomass-based carbon storage. This study assessed mangrove diversity, structure, biomass, and carbon stocks in two key locations: Banyuurip Mangrove Center (BMC) and Lewean Mangrove Park (LMP), located in the Ujungpangkah Estuary, Gresik. Data were collected from 15 rectangular plots (10 × 10 m) to determine species composition, tree density, Importance Value Index (IVI), above and belowground biomass, and estimated carbon stocks using standard allometric equations. A total of 12 mangrove species were identified, with Avicennia marina emerging as the dominant species in all growth stages across both sites. Tree density varied from 100 to 1,600 trees/ha, reflecting stages of regeneration rather than degradation. The highest IVI values were recorded for A. marina (196.3% in BMC; 146% in LMP). Total biomass and estimated carbon stock were higher in BMC (340.48 Mg/ha; 164.87 Mg C/ha) compared to LMP (125.67 Mg/ha; 56.20 Mg C/ha), primarily due to differences in species dominance and stand maturity. These results underline the ecological and climate mitigation significance of maintaining mangrove diversity and biomass. The study supports the integration of mangrove conservation into blue carbon strategies for sustainable coastal management, and recommends strengthening local restoration initiatives based on dominant species performance.
