Abstract

This research was conducted in Bagan Hulu Village, Bangko District, Rokan Hilir Regency, Riau Province on November 21 - December 09, 2022, to analyze the profit-sharing system for drift gill net fishermen and compare the profit-sharing system that applies in Bagan Hulu Village with the Law No.16 of 1964 concerning profit sharing. The method used was a survey with a total sample of 32 fisherman owners; the sampling technique was simple random sampling. The results showed that the profit-sharing system for drift gill net fishermen in Bagan Hulu Village, Bangko District, Rokan Hilir Regency, Riau Province, uses a local profit-sharing system by sharing profits after deducting production costs with a percentage of 60% for fisherman owners and 40% for labor fishermen provided that all operational costs are shared. From a comparison of the profit-sharing system according to UUBHP, the share of income for fishermen who own drift gill nets in Bagan Hulu Village is greater than that according to UUBHP. The difference can be seen from the joint costs incurred. In the law, the shared costs incurred are consumption, while in the Bagan Hulu Village, the shared costs incurred are all operational costs

Abstract

Commercial feed contributes to the operational costs of aquaculture production activities. On the other hand, making your feed requires formulation and availability of raw materials in maintained quantity and quality. Local feed raw materials can be used as alternative ingredients. Still, one of the obstacles is several limiting factors, such as crude fiber and the binding of some essential nutrients, such as protein and minerals. Hence, nutrient utilization is low and has a direct impact on growth. Adding feed additives as sources of enzymes is considered to help speed up the digestive process so sufficient nutrients are available for growth and survival. Enzymes break down large molecules such as crude fiber starch, increasing protein and fat into forms easily digested and absorbed by fish. This paper aims to review the use of enzymes to improve the quality of fish feed ingredients. The method used is Literature Review. Improving the quality of feed raw materials with the help of enzymes can increase the quality of fish feed ingredients. Application of enzymes in fish feed as additional feed ingredients (feed additives) through the addition of commercial enzymes, enzymes from plant or animal extracts, and microbial enzymes

Abstract

This study aimed to determine and analyze the economic value of the mangrove ecosystem in Rempang Island, Batam City, Kepulauan Riau Province. The survey method used a quantitative approach to analyze the economic valuation with the calculation of Total Economic Value (TEV), which consists of the calculation of use value: direct use value, indirect use value, option value, and non-use value: existence value and bequest value. There were 44 respondents determined by the Slovin method. The results showed that the total economic valuation of mangrove ecosystems on Rempang Island with an area of 2,813.18 ha which is IDR 75,082,590,695/year, consisting of a total use value which is IDR 74,739,030,695/year and total non-use value which is IDR 343,560,000/year. The use value is obtained from direct use value which is IDR 2,059,200,000/year from fish, shrimp, and crab utilization activities, indirect use value which is IDR 72,004,878,483/year from breakwaters and abrasion, preventing seawater intrusion, nursery ground, feeding ground, spawning ground, and an optional value which is IDR 674,952,212/year from the value of biodiversity. Then, the total non-use value is obtained from the willingness to pay IDR 137,640,000/year and bequest value IDR 205,920,000/year. These findings indicate that the current ecological condition of the Rempang Island mangrove ecosystem has provided excellent economic value, so efforts are needed to maintain this condition with sustainable management
