Catfish cultivation wastewater and agricultural waste can be used as an alternative planting medium and a source of nutrients in organic hydroponic cultivation systems. This study aimed to determine the plant nutrient content in catfish culture wastewater added with cow dung, chicken manure, trash fish waste, and catfish waste; and to determine the growth of mustard greens and lettuce which were cultivated hydroponically in a growing medium of catfish wastewater added with cow dung, chicken manure, trash fish waste, and catfish waste. The results showed that the solution of catfish culture wastewater added with catfish waste contained nutrients N 220.0 ppm, P 166.3 ppm K 154.4 ppm Ca 65.9 ppm Fe 4.4 ppm; catfish culture wastewater added with trash fish waste contains 50.0 ppm N; P 10.8 ppm; K 173.4 ppm; Ca 219.4 ppm and Fe 3.2 ppm; catfish culture wastewater added with cow dung contained nutrients N 300.0 ppm, P 293.4ppm K 1026.8 ppm Ca 413.6 ppm Fe 64.9 ppm, while those given chicken manure included N 100.0 ppm; P 76.1 ppm; K 471.1ppm; Ca 299.9ppm and Fe 27.3ppm. While catfish culture wastewater contains 55.2 ppm of N nutrients; P 6.4 ppm; K 7.0 ppm; Ca 14.2 ppm; Fe 0.4 ppm. The growth of lettuce in the growing media of catfish culture wastewater given trash fish and catfish was relatively the same, namely 37.7% and 37.9%, respectively. Meanwhile, the growth of mustard pakcoy grown on planting media given chicken manure (47.6%) was higher than the growth of mustard pakcoy grown on cow dung (33.3%). The addition of 50% ABmix nutrients increased the growth of mustard pakcoy on media that was given chicken manure by 81.7%; pakcoy on media that was given cow dung waste by 74.8%; Meanwhile, the addition of ABmix 50% nutrients increased the growth of lettuce on media that was given catfish meal by 64.4%, and on media that was given trash fish meal by 61.9%. Research shows a high potential for using organic waste as a medium and source of organic hydroponic cultivation fertilizer.","PeriodicalId":397828,"journal":{"name":"AGRITROPICA : Journal of Agricultural Sciences","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130304875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research location was determined purposively, and 86 dried fish makers were selected using the census method. The data used are primary and secondary, and the data analysis used is qualitative and quantitative. Sources of raw materials in dried fish are divided into three: self-catch, buy, and self-catch and buy. The largest percentage of sources of raw materials is to buy, where the place to get the most comes from fishermen directly. The quantity of raw material used is 10,563 Kg per production process. The factors that partially affect the quantity of demand for fresh fish by dried fish makers are the price of ice and the dummy of the business scale at the 95% confidence level.","PeriodicalId":397828,"journal":{"name":"AGRITROPICA : Journal of Agricultural Sciences","volume":"289 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122918693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spacing will affect the density and efficiency of light use and competition between plants in the use of water and nutrients to affect crop production. At low densities, plants compete less with other plants so that individual plant performances are better. Conversely, at high densities, the competition between plants for light, water, and nutrients is getting tighter so that plant growth can be stunted. Each kara oncet bean cultivar responds differently to different plant density levels. The experiment was conducted in farmers' rice fields in Lembang with Andosol soil. The altitude is 1500 m above sea level. Cangar and Bromo kara oncet bean cultivars with populations of 83,333 plants per ha, 66,667 plants per ha, and 55,556 per ha were studied using factorial block design with four replications. The response surface methodology and snugness test responses to find the highest population of each kara oncet bean cultivar. From the experimental results, it turns out that different plant populations cause differences in (ILD), (LTT), (LAB), and results. The optimum population to obtain the highest yield of two faba bean cultivars has not yet been determined. The components of plant organs that can be relied upon as a determinant of the yield of kara oncet beans are the number of pods per plant, the number of seeds per plant, and the weight of 25 dry seeds.","PeriodicalId":397828,"journal":{"name":"AGRITROPICA : Journal of Agricultural Sciences","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117120555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
