This condition has the potential to make the sugar factory a model of a closed system sugar factory, because the increase in white crystal sugar (GKP) production will increase the by-products (bagasse, filter cake, molasses and wáter). The closed system sugar factory is a GKP factory integrated with the power generation and clean water treatment industries. In this model, the raw material for sugar cane is not only used as sugar but also as a source of renewable energy and clean water. The purpose of this study was to analyze the potential utilization of by-products in the form of bagasse, filter cake, molasses and water in white crystal sugar factories. The research method is mass balance using input, process and output data at the sugar factory and secondary data. The results of this study have provided information about the potential for energy and water in closed system sugar production. The energy potential for power generation from blotong is 1 730.2 MJ/ton GKP, molasses is 5 939.0 MJ/ton GKP. The energy consumption at the power plant from blotong is 56.1 MJ/ton GKP, molasses is 408 MJ/ton GKP. The potential for clean water from water treatment for 1 ton of GKP is 4.6 tons, equivalent to 0.4 tons of clean water per ton of sugarcane.","PeriodicalId":14951,"journal":{"name":"Journal of Agriculture","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80702696","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}

This is because vannamei crustaceans have favorable prospects and profits. Traditional Vannamei shrimp cultivation has great development potential, but preventing parasites and diseases that originate in the pond water when cultivating shrimp is impossible. The incidence of disease is closely correlated with parameters of water quality. Pathogenic microorganisms, specifically the Vibrio sp. bacteria, are responsible for one of the prevalent maladies affecting vannamei shrimp farms. Vibrio sp. bacteria produces vibriosis, the clinical symptoms of brownish-red gills, a crimson uropod and abdominal telson, and a sluggish swimming speed.

The research will be conducted in the seaweed cultivation area of Mandalle Village, Pangkajene Islands Regency. The determination of research stations was carried out purposively (purposive sampling) for three representative aquaculture stations. This is so that it can represent or describe the condition of the waters of Mandalle Village. The cultivation method used in this study was the long line method as used by residents around the study site. Maintenance construction as a sampling unit at each station point, in the form of a 25-meter long rope span of 10 ropes with a distance between the ropes of 1 m. Each stretch rope contains 100-120 seedling clumps with a distance of 20 cm between the straps. Seaweed seeds with an initial weight of 50-70 grams, tied to clump ropes. Planting of seeds is carried out at a depth of 30 cm from the surface of the water. The cultivation construction distance is installed as far as 700-1000 m from the beach. Observation of growth is done by measuring the weight of each clump or the overall weight of each clump of each span rope, at the end of each maintenance cycle. The data obtained for 45 days is then calculated using the growth formula. Seaweed samples for observation of ectoparasites were taken at 3 (three) points of the cultivation area for each bundle of seaweed. The entire surface of the sample thallus was observed with the naked eye and the loop. The results of this study indicated that all observation stations on the South, North and West coasts were dominated by barnacle ectoparasites, followed by green mussels and worms with a total percentage of 90%.

Issues about the environment and low soil organic nutrient content also occur in Jember District, especially in Kalisat District, which causes the importance of applying organic fertilizers. The importance of using organic fertilizers requires the participation of farmer groups to be more empowered in producing and using organic fertilizers. The purpose of this study was to analyze the needs and constraints faced to develop a strategy for developing a farmer group empowerment program in the use of organic fertilizers in the Kalisat subdistrict, regency Jember. This research is classified as a qualitative research which aims to analyze the key factors in the farmer group empowerment program. The results showed that in the elements of program needs there were two needs which were key factors, namely organic farming production facilities and local government policies. In the element of constraint there are two key obstacles namely the low knowledge of farmers and the limitations of organic fertilizer processing tools and machines. The resulting strategy is in the form of: 1) Addition of organic farming production facilities. 2) Alignment of local government policies by adding programs to promote the use of organic fertilizers in Jember Regency in the main program of Jember Mandiri. 3) Increase farmer's knowledge related to the manufacture of organic fertilizers through counseling.","PeriodicalId":14951,"journal":{"name":"Journal of Agriculture","volume":"122 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74831473","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}
