Abstract

Occupational Health and Safety (OHS) is vital in high-risk environments, especially on research vessels conducting deep-sea sampling operations. The increased risk of accidents in maritime research requires an urgent focus on implementing specialized OHS systems. This study aims to analyze the application of OHS during deep-sea sediment sampling on the KM Madidihang 03 vessel. The research employs a descriptive design using the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method. Data were collected through direct observation during operations, utilizing modified Box Core and Gravity Core equipment for sediment collection. The hydraulic crane and tension meter were used to ensure the safe operation of these instruments. Data were analyzed to identify hazards, assess risks, and implement appropriate control measures. The results indicate that equipment failure, such as crane malfunction and cable breakage, poses the highest risk, necessitating regular equipment maintenance and safety training. The study recommends enhancing OHS procedures, including stricter supervision and crew training, to mitigate accidents and improve safety on research vessels. Future studies should focus on developing advanced safety protocols tailored to modified deep-sea research operations.

Abstract

This study aims to estimate the fishing effort for skipjack tuna (Katsuwonus pelamis) landed at Sadeng Coastal Fishing Port, Yogyakarta, under three management conditions: Maximum Sustainable Yield (MSY), Maximum Economic Yield (MEY), and Open Access Equilibrium (OAE), using the Fox model. The Fox model includes a key variable that helps balance ecological sustainability with economic profitability, ensuring the long-term viability of both the fishery and the livelihoods it supports. The skipjack tuna assessed in this study were caught using purse seines in the Indian Ocean south of Yogyakarta. Catch and fishing trip data from 2015 to 2021 were analyzed using the Fox bioeconomic model, a development of the Gordon-Schaefer model. The research was conducted from March to May 2022. Under MSY conditions, the estimated catch (CMSY) was 493,012 kg with an effort (EMSY) of 170 trips per year, yielding an annual profit of IDR 4,768,675,442. Under MEY conditions, the estimated catch (CMEY) was 474,424 kg with an effort (EMEY) of 127 trips, resulting in a higher annual profit of IDR 5,071,245,038. Under OAE conditions, the estimated catch (COAE) was 337,761 kg with an effort (EOAE) of 363 trips per year. Based on the Fox model, the current fishing effort is at 70% of EMSY, indicating that the skipjack tuna fishery in this area is not overfished.
