This study aims to investigate the optimum dosage of Bokashi and Phonska NPK fertilizer on the growth and production of the Inpari 42 rice variety. This investigation was conducted at the agricultural location of Ulu Mowewe Village, Mowewe District, East Kolaka Regency. The experiment used was the Split Plot Design (RPT). The factorial pattern consists of two treatment factors, namely the Bokashi (B) treatment factor with three levels, namely: B1 = 1.2 kg/plot, B2 = 2.4 kg/plot, and B3 = 4.8 kg/plot, and the treatment factor Phonska NPK, which consists of three levels, namely N1 = 0.18 kg/plot, N2 = 0.36 kg/plot, and N1 = 0.54 kg/plot. Parameters observed in the study were: plant height, number of tillers, number of leaves, leaf length, leaf width, panicle length, number of panicles or clumps, number of grain or panicles, number of filled grain or panicles, the weight of 1000 grain grains, dry milled grain yield (GKG) per plot, Milled Dry Unhulled grain yield (GKG) per conversion. The data were processed using variance (ANOVA) and followed by the Least Significant Difference Test (LSD). Based on the results of the study, it can be concluded that the combined dose of Bokashi and Phonska NPK fertilizer significantly affected plant height (cm), the number of tillers, the number of leaves (strands), leaf length (cm), leaf width (cm), panicle length (cm), number/panicle, total grain/panicle, total grain/panicle, and yield of dry milled grain (GKG)/slot (kg), the yield of dry milled unhulled grain (GKG)/conversion (tons) The dose treatment of Bokashi and Phonska NPK showed that the optimum combination dose of Bokashi and Phonska NPK for the growth and yield of Inpari 42 rice was B3N2 (4.8 kg and 0.3 kg/plot).

The production and demand for sugar in Indonesia increases every year. 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.

Vannamei shrimp is a species of shrimp that is frequently cultivated using conventional methods. 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. This study aimed to determine the correlation between Vibrio sp. bacteria content and water quality parameters in conventional vannamei shrimp (Lithopenaeus vannamei) cultivation. This study employed exploratory methods and purposive sampling for its sampling. Isolation of microbes using selective media containing TCBSA. The colony abundance of Vibrio sp. bacteria was calculated using the Total Plate Count method. The results showed no significant correlation between the quality of pond water and the abundance of Vibrio sp. bacteria colonies in the traditional system of vannamei shrimp (Lithopenaeus vannamei) cultivation, with a correlation value of > 0.05.

This study aims to determine the types of ectoparasites found in the thallus of cultivated seaweed Kappaphycus alvarezii and their effect on their growth. 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%. While the absolute growth between all stations is relatively the same.

Procurement of organic fertilizers is one of the efforts that can be made to restore soil organic matter to increase the production value of the agricultural sector in Jember Regency. 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.
