<strong>Abstract. </strong>Inadequate processing of waste in household areas has resulted in many people throwing the waste anywhere. Waste generation can be minimized by using the composting method. There are many methods of composting organic waste; one of them is the <em>Tong</em> Composter. <em>Tong</em> Composter is a composting method which in the process uses an EM4 bio-activator. <strong>Objectives:</strong> This research objective is to determine whether the liquid organic fertilizer parameters produced comply with the standard of Ministerial Decree of Agriculture No. 261 of 2019. <strong>Method and results:</strong> This research using the experimental method with two treatments, EM4 dosage (60 ml and 70 ml) and fermentation time (10 days and 20 days). A dose of EM4 in treatment 1 is 60 ml, and treatment 2 is 70 ml; each treatment was analyzed on the 10<sup>th</sup> day. For treatment 3 and 4, a dose of EM4 in treatment 3 is 60 ml, and in treatment 4 is 70 ml; each treatment was analyzed on the 20<sup>th</sup> day. Then from the liquid organic fertilizer produced, several parameters were analyzed at PT. Sucofindo Cibitung, such as Nitrogen, P<sub>2</sub>O<sub>5</sub>, and K<sub>2</sub>O parameter. Meanwhile, the pH will be measured in the Environmental Engineering Laboratory of President University. The laboratory experiment results from pH, Nitrogen, P­<sub>2</sub>O<sub>5</sub>, and K<sub>2</sub>O will be tested using the t-test. With the hypothesis (H<sub>O</sub>: µ sample ≥ minimum value of macro-nutrient and pH parameter from Ministerial Decree of Agriculture of the Republic of Indonesia Number 261 of 2019). According to the t-test result, the null hypothesis is rejected because Nitrogen, P<sub>2</sub>O<sub>5</sub>, and K<sub>2</sub>O in all parameters are less than 2%. The null hypothesis is accepted for pH because in all parameters is higher than or equal to 4. <strong>Conclusion:</strong> The t-test result showed that only the pH was complied with the standard, while the Nitrogen, P­<sub>2</sub>O<sub>5</sub>, and K<sub>2</sub>O parameters have not complied with the standard of Ministerial Decree of Agriculture No. 261 of 2019.

Macro Nutrients

Liquid organic fertilizer is a solution from the fermentation of organic materials by involving microorganisms as a destructor of macromolecular compounds into minerals that are easily absorbed by plants. The quality of organic fertilizers is the main ingredient to get productive plants. The quality of organic fertilizer is determined by the concentration of macro nutrients such as nitrogen (N), potassium (K), and phosphorus. Getting high amounts of macronutrients fertilized organically is not easy. Macro-nutrients in organic waste with high concentrations are very difficult to obtain because each organic waste does not have all three macro-nutrients simultaneously. It takes a combination of organic waste to increase the concentration of macro nutrients in organic fertilizers. The combination of tofu whey with banana waste is one technique to obtain organic fertilizers that are high in phosphorus content. This study aims to obtain the effect and conditions of fermentation on the addition of mass of banana waste to produce optimum levels of phosphorus (P) in liquid fertilizer of tofu waste. The type of research used is pre-experimental research. The design of this study used a completely randomized design (CRD) with two factors, namely the first factor was the mass of banana waste (X) (X1 = 250 grams, X2 = 500 grams, X3 = 750 grams) and the second factor was the fermentation time (Y) (Y1 = 14 days, Y2 = 28 days, Y3 = 42 days). Determination of phosphorus content using UV-Vis spectroscopy instrument. Parameters measured were phosphorus (P) levels in liquid organic fertilizer. The independent variables in this study were the mass of banana waste and fermentation time, while the dependent variable in this study was the phosphorus content of the liquid fertilizer produced. The results of the analysis show that the phosphorus content (P) produced is X1Y1 = 0.1%, X2Y1 = 0.5%, X3Y1 = 0.09%, X1Y2 = 0.5%, X2Y2 = 2%, X3Y2 = 1.9 %, X1Y3 = 0.2%, X2Y3 = 0.5% and X3Y3 = 0.5%. There is an effect with the addition of a mass of banana waste as much as 250 grams at a 12-day fermentation time. It can be concluded that the liquid fertilizer produced has exceeded the SNI quality standard.

Energy is one of the main pillars of the state’s economy, which is currently facing serious problems due to depletion of mineral energy resources and the threatening environment. As a result, presently around the world there is a rapid growth and development of energy-efficient technologies and the use of renewable energy sources (RES), providing an increase in energy resources, as well as environmental and social effects. One of the most relevant and promising areas of renewable energy development is the disposal and processing of organic waste in biogas plants, and this is particularly relevant in agricultural regions. In this regard, this paper considers the state and prospects for the development of bioenergy in agricultural regions of Uzbekistan, where half of the population of the republic lives. The potential of organic waste from livestock and poultry farming of the agricultural sector was determined, and it was revealed that the use of biogas plants for the disposal of manure and litter is clearly a profitable production and requires close attention from rural producers. The introduction of biogas technologies for the bulk of agricultural producers is an urgent task, that will ensure not only a solution to the waste problem, but it will also provide a solution to energy, agricultural, environmental and social problems in rural regions of the republic.

Nutritionally unbalanced organic waste can be converted into potential resources for animal and plant farming by culturing black soldier fly (Hermetia illucens) larvae (BSFL) and prepupae (BSFP). BSFL and BSFP are rich sources of protein and lipids, while the leftover excrement called “frass” can be used as an organic fertilizer. Using readily available resources, BSFL were cultured on spent coffee, donut dough or an equal blend for 35 days. Survival, productivity, daily pupation and biochemical composition of BSFL and BSFP were measured along with the nitrogen-phosphorus-potassium values of the frass. Survival was highest in the blend compared (81%) to spent coffee (45%) or dough (24%); however, BSFL and BSFP were significantly longer and heavier from dough. Stage and food significantly influenced the protein, lipid and glycogen content of the BSFL and BSFP, which tended to be higher in the latter. While fatty acids were often significantly higher in BSFL fed spent coffee, the amino acid composition of BSFL was generally higher in dough. Frass from the blend had significantly highest nitrogen content, while potassium and phosphorus were significantly higher and lower from spent coffee, respectively. Although coffee and donut dough were suboptimal substrates for BSFL, a blend of these produced BSFL and frass that were nutritionally comparable to soybean meal and many organic fertilizers, respectively.
