Abstract

This study aims to identify and analyze the diversity of coral fish in the marine waters of Central Tapanuli Regency, which includes the areas of Mursala Island, Binasi Beach, and Pandan Waters. The method used is a qualitative approach with field observation, visual identification of species, and interviews with coastal communities. The results showed that there were 35 species of reef fish from 12 families identified, with Mursala Island being the location with the highest diversity. The dominant families include Pomacentridae, Chaetodontidae, and Labridae. Variations in diversity between locations are influenced by coral reef conditions, human activities, and the quality of the aquatic environment. Population declines of some reef fish species were also identified, which were related to environmentally unfriendly fishing practices and habitat degradation. These results reinforce the importance of sustainable management of marine resources by involving local communities as the main actors of conservation. This research provides an initial overview of the potential for marine biodiversity in Central Tapanuli and is the basis for coral reef ecosystem conservation policies in western Indonesia.

Abstract

This research aims to determine the supply chain for tuna fish at the Belawan Ocean Fisheries Port (PPS). The research was conducted at the Belawan Ocean Fisheries Port (PPS), North Sumatera Province. The data collected included observation, interviews and literature research (excavating secondary sources). The research results show that the results of the analysis of the tuna fish supply chain show that there are four supply chains and four actors. The shorter the supply chain and the smaller the marketing margin, the greater the profits and marketing costs received. This indicates that marketing of tuna fishery production will be more efficient, and vice versa. The shortest supply chain alternative is highly recommended to ensure stock availability, minimize prices, increase profits, empower local assets and culture of North Sumatara Province which must be maintained, and the role and contribution of the government is really needed, especially when the availability of tuna stocks is abundant.

Abstract

This research aims to analyze the performance of the shallot supply chain in Samosir Regency. Place and Time of Research This research was conducted in Samosir Regency, North Sumatra Province. Data Collection and Analysis Analysis of the Condition of the Shallot Supply Chain The condition of the shallot supply chain is discussed descriptively following the FSCN (Food Supply Chain Network) discussion framework developed by Van der Vorst. The research results show that shallot supply chain activities in Samosir Regency are based on a food supply chain networking model where fluctuating prices and weather are the main inhibiting factors in supply chain activities starting from product availability to delivery. Measuring the performance of the shallot supply chain using the Supply Chain Operations Reference (SCOR) method has not shown optimal results on all indicators such as delivery performance, standard compliance and conformity with standards. Judging from the profit shares of producers, collectors and retailers, they differ from each other, this reflects the unequal profits of each trading system so that the trading system in this area is not yet efficient. In general, the shallot trading system in this village is not yet efficient. It is a good idea for farmers themselves to sort and sort small, medium and large shallots. So that the selling price can also increase and be more profitable.
