Abstract

The objective of this research was to determine the efficiency and productivity of gillnet mesh size in North Galesong District, Takalar Regency. The type of research was survey research with a quantitative descriptive approach to obtain a sample from a population that describes or explains catch production, productivity, and efficiency of gillnet fishing gear. The population of this research was 40 cantrang fishermen who switch to using gillnet fishing gear in North Galesong District. The sample was all cantrang fishermen who switched to gillnet fishing gear. The sampling method employed in this study was a census sampling strategy, where all members of the population were used as samples. The methods of data collection were questionnaires, observations, and interviews. The results showed that the most efficient gillnet mesh size of the five mesh sizes 1 inch, 1.5 inch, 2 inch, 2.5 inch and 6 inch is the 1.5 inch mesh size with a value of 3.90. The results of the calculation of the productivity of gillnet fishermen in each mesh size has a different value. The highest gillnet productivity was at 1 inch mesh size with a value of 44.40kg/trip, then the lowest productivity was at 2.5 inch mesh size, which was 24.39 kg/trip.

Abstract

This study aims to determine the amount of macronutrient content of nitrogen, phosphate and potassium from catfish culture waste as liquid organic fertilizer (POC) through a fermentation process at different times. As well as knowing the potential economic value, by determining the cost of production and the selling price of catfish farming waste products as liquid organic fertilizer in Benteng Somba Opu Village, Barombong District, Gowa Regency. This research was carried out for three months, from February to April 2021. The fermentation process used a simple experimental research design method, while the potential economic value used a quantitative descriptive research method. The results of the study on catfish culture wastewater contained N, P and K. Macro nutrient levels of catfish manure containing N (nitrogen) ranged from 0.98 - 1.67%, P (phosphorus) 1.89 - 3.40 % and K (potassium) 0.10-1.03%. Apart from the content of macro-nutrient levels to improve macro-nutrients in the soil, POC also provides additional income for catfish cultivators. HPP based on research results is Rp. 19,000 / liter. Comparison of the price of poc in the market with liquid organic fertilizer that has been fermented by comparing 3 brands of poc on the market with the same size, namely 1 liter. The average profit potential of liquid organic fertilizer from catfish farming waste in a month (30 days) is Rp. 884,190, / Month, where the desired POC selling price ranges from Rp.47,500-Rp.52,000,-. Although the potential is small, it is quite interesting for catfish cultivators to try. This is in line with the increase in the production process of catfish cultivation, so additional income in the production of liquid organic fertilizer will also increase.
