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).
本试验旨在探讨博卡施和峰斯卡施氮磷钾对英丽42号水稻生长和生产的影响。这项调查是在东科拉卡县莫韦区乌鲁莫韦村的农业地点进行的。试验采用分图设计(Split Plot Design, RPT)。析因模式由两个处理因子组成,即Bokashi (B)处理因子具有3个水平,即B1 = 1.2 kg/plot, B2 = 2.4 kg/plot, B3 = 4.8 kg/plot;处理因子Phonska NPK具有3个水平,即N1 = 0.18 kg/plot, N2 = 0.36 kg/plot, N1 = 0.54 kg/plot。研究中观察到的参数为:株高、分蘖数、叶片数、叶长、叶宽、穗长、穗或团数、粒数或穗数、灌浆粒数或穗数、千粒重、每小区干磨粒产量(GKG)、每转化干磨去壳粒产量(GKG)。采用方差分析(ANOVA)对数据进行处理,然后进行最小显著性差异检验(LSD)。综上所述,博卡施与峰斯卡施氮磷钾配施量对水稻株高(cm)、分蘖数、叶数(株)、叶长(cm)、叶宽(cm)、穗长(cm)、穗数/穗数、总粒数/穗数、总粒数/穗数、干粉粒产量(GKG)/槽(kg)有显著影响;博卡施和峰斯卡氮磷钾的剂量处理表明,博卡施和峰斯卡氮磷钾对英巴利42号水稻生长和产量的最佳组合剂量为B3N2 (4.8 kg和0.3 kg/田)。

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.
印尼的糖产量和需求量每年都在增加。这种情况有可能使糖厂成为封闭系统糖厂的典范,因为白色结晶糖(GKP)产量的增加将增加副产品(甘蔗渣、滤饼、糖蜜和wáter)。封闭式制糖厂是一家集发电和净水处理行业于一体的GKP工厂。在这个模型中,甘蔗的原料不仅可以作为糖,还可以作为可再生能源和清洁水的来源。本研究的目的是分析白结晶糖厂副产物甘蔗渣、滤饼、糖蜜和水的利用潜力。研究方法是利用糖厂的输入、加工和输出数据和二次数据进行质量平衡。本研究的结果提供了关于封闭系统糖生产中能量和水的潜力的信息。棉花糖的发电潜力为1 730.2 MJ/吨GKP,糖蜜的发电潜力为5 939.0 MJ/吨GKP。焦炭在电厂的能耗为56.1 MJ/吨GKP,糖蜜的能耗为408 MJ/吨GKP。1吨GKP的水处理潜力为4.6吨,相当于每吨甘蔗生产0.4吨清洁水。

Lake Ranau is located on the border of West Lampung Regency, Lampung Province and South Ogan Komering Ulu Regency, South Sumatra Province. Lake Ranau has functions including ecological and socio-economic cultural functions. Some important technical       aspects in a tilapia aquaculture business in KJA include KJA components, maintenance/production processes ranging from seed stocking, feeding to harvesting and constraints faced by farmers during the production process. The criteria observed in determining the feasibility of tilapia KJA cultivation include: investment costs, profits, profitability, BEP (Break Event Point) and R / C Ratio (Revenue Cost Ratio). Economically, tilapia aquaculture in KJA in the waters of Lake Ranau is profitable and feasible for both category I and category II. The profitability value of this KJA farming business is 115% for category I and 119% for category II. The R/C ratio value in one production cycle is 2.15 for category I and 2.19 for category II which means the business is feasible to establish.

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.
凡纳美虾是一种常用常规方法养殖的虾。这是因为南美甲壳类动物具有良好的前景和利润。传统的凡纳美对虾养殖具有很大的发展潜力,但在养殖对虾的过程中,不可能预防来自池水的寄生虫和疾病。病害的发生与水质参数密切相关。致病微生物,特别是弧菌属细菌,是影响南美虾养殖场的一种普遍疾病的罪魁祸首。弧菌属细菌产生弧菌病,临床症状为鳃呈棕红色,尾足和腹部呈深红色,游泳速度缓慢。本研究旨在探讨凡纳滨对虾(litopenaeus vannamei)常规养殖中弧菌含量与水质参数的相关性。本研究采用探索性方法和目的性抽样进行抽样。用含TCBSA的选择性培养基分离微生物。采用总平板计数法计算弧菌菌落丰度。结果表明,在传统的凡纳滨对虾养殖体系中,池水水质与凡纳滨对虾(Lithopenaeus vannamei)养殖体系中弧菌菌落丰度无显著相关,相关值> 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.

This study compares the degree of adaptation of four shallot varieties introduced to the sub-optimal land of Wamena with one local variety. The study determined the physiological processes of plants observed 5 and 11 weeks after planting. The results show that the best-adapted shallot is the local variety which is indicated by the parameter of harvest index (0.820). In addition, the results showed that the local Wamena variety produced high production with a high assimilation rate (0.072 g/dm2week-1), had a leaf area (41,750 cm) and a high leaf area value (0.465 cm) even though it was indicated by treatment without fertilizer application.

This study aims to determine the potential of soil carbon on dry land in Aceh Besar regency. This study uses a descriptive method based on field results and surveys and laboratory analysis. Soil sampling at various depths was carried out for carbon and bulk density analysis. Composite soil samples were taken at a depth of 0-5, >5-10, >10-20, >20-30, >30-70, and >70-100 cm. The type of land use is bush covering an area of ??96,962.2 ha, moor 313.03 ha, rainfed rice fields 4,478.67 ha and mixed gardens 15,052.09 ha. The highest percentage of soil carbon is in the mixed garden land utility type (3.40%) compared to other types of utility. the highest carbon potential is found in the bush land utility type (137.68 tons/ha) compared to other types of utility.  The highest soil carbon stock is in the type of land use of bush compared to other types of land utility. This is because the bush land utility type has soil carbon potential and a large area compared to other land utility types.
本研究旨在确定亚齐省省旱地土壤碳的潜力。本研究采用基于实地结果、调查和实验室分析的描述性方法。在不同深度取样土壤进行碳和容重分析。复合土样采深分别为0 ~ 5、>5 ~ 10、>10 ~ 20、>20 ~ 30、>30 ~ 70、>70 ~ 100 cm。土地利用类型为灌木林面积96,962.2公顷,沼地面积313.03公顷,旱作稻田面积4,478.67公顷,混合花园面积15,052.09公顷。与其他利用类型相比,混合园地利用类型土壤碳含量最高(3.40%)。与其他类型的公用事业相比,灌木土地公用事业类型的碳潜力最高(137.68吨/公顷)。与其他土地利用类型相比,灌木土地利用类型的土壤碳储量最高。这是因为与其他土地利用类型相比,灌木土地利用类型的土壤碳潜力大,面积大。

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.
采购有机肥料是恢复土壤有机质以增加琼月摄政农业部门生产价值的努力之一。在Jember地区,特别是Kalisat地区也存在环境和土壤有机养分含量低的问题,这使得施用有机肥的重要性。使用有机肥料的重要性要求农民团体在生产和使用有机肥料方面有更大的参与能力。本研究的目的是分析在制定一项战略时所面临的需求和限制,该战略旨在制定一项农民团体在使用有机肥料方面的赋权计划。本研究属于定性研究,旨在分析农民群体赋权计划的关键因素。结果表明,在项目需求要素中,有机农业生产设施需求和地方政府政策需求是关键因素。在制约因素中,有两个主要障碍,即农民知识水平低和有机肥加工工具和机器的局限性。由此产生的战略形式是:1)增加有机农业生产设施。2)通过在Jember Mandiri的主要项目中增加Jember Regency的有机肥料使用推广项目,与当地政府政策保持一致。3)通过咨询增加农民对有机肥料生产的相关知识。
