The Effectiveness of Biochar and Compost-Based Fertilizers in Restoring Soil Fertility and Red Chili Yields Yohanes Parlindungan Situmeang, Made Suarta, I Dewa Nyoman Sudita, Ni Luh Putu Sulis Dewi Damayanti Agrivita, 2024 The livestock areas are characterized by vast quantities of animal wastes that can be used as organic manure through composting and biochar production for soil fertility enhancement. This work aim s to estimate the potential of increasing soil fertility and red chili production by employing biochar and poschar from different animal wastes. The design used for this study i s a factorial pattern and randomized block. The first factor i s the type of biochar used, including no biochar, biochar derived from cow manure, biochar derived from goat manure, and biochar derived from chicken manure. The second factor i s the type of poschar; this includes poschar derived from cow manure, poschar derived from goat, poschar derived from chicken manure. It can be concluded from the investigation outcomes that applying biochar and poschar substantially affects soil factors such as water content, pH, EC, humic acid, fulvic acid, C, N, P, K, and CEC values. Red chilies increase and yield higher per hectare when various forms of biochar and poschar are applied. The combustion of cow manure and application of biochar products and biochar made from chicken manure produce the highest agronomic performance.

THE EFFECT OF ECO-ENZYME SPRAYING ON SUWUNG LANDFILL WASTE, DENPASAR, ON CHANGES IN LEACHATE CHARACTERISTICS I Nengah Muliarta, I Dewa Nyoman Sudita, Yohanes Parlindungan Situmeang Jurnal Kesehatan Lingkungan, 2023 Introduction: Bali, as an international tourist destination, is still experiencing problems in waste management. Suwung Landfill, Denpasar, is one of the landfills for waste originating from the Denpasar, Badung, Gianyar, and Tabanan (Sarbagita) areas. Methods: This research was an experimental study, by watering eco-enzymes on garbage heaps and examining changes in leachate parameters. Watering was carried out daily at a dose of 1 L of eco-enzyme dissolved in 1000 L of water and used for watering a garbage pile of 1 ha. The area of piles of garbage watered with eco-enzymes reaches 5 ha. Measured leachate parameters include pH, BOD, COD, TSS, N, cadmium, and mercury. Results and Discussion: Eco-enzymes have the potential to become activators or decomposers in waste composting. The evidence is that eco-enzyme watering causes the average leachate temperature to range from 36.63 to 40.370C, where the increase in leachate temperature occurs due to the rise in the temperature of the garbage pile. An increase in temperature characterizes the activity of microbes increases, so the decomposition process becomes rapid. Conclusion: Eco-enzyme spraying leads to a characteristic change in the form of an increase in the value of leachate parameters. The increase in temperature value, pH, BOD, COD, and N content of leachate indicates that environmentally friendly enzymes accelerate the decomposition of organic matter. The rapid decomposition process causes the total suspended density of leachate to increase.
Application of relativistic quantum mechanics in radial problems and E/M equations Gede Yohanes Arygunartha, Ni Made Defy Janurianti, Yohanes Parlindungan Situmeang Journal of Physics Conference Series, 2021 Abstract This research is pure research in the field of pure physics. The background of the research that I did there was doing pure research in the field of physics. The subject of this research is to use the e/m measurement tool. This study aims to (1) study the influence of the magnitude of the electron velocity and the magnitude of the magnetic field on the electron path, (2) determine the e/m ratio in calculations. The results showed that the magnitude of the electron path radius is directly proportional to the magnitude of the electron velocity and inversely proportional to the magnitude of the magnetic field acting on it. Meanwhile, the calculation result for fixed current is 16.84% and the fixed voltage is 14.15%, in this case the size of the electron path is directly proportional to the magnitude of the speed of the electron path, and inversely proportional to the magnitude of the magnetic field acting on the electron.
Application of manure types in breeding several varieties of chili (Capsicum frutescens L.) M S Yuliartini, A A N M Wirajaya, A U R Z Assegaf, Y P Situmeang Journal of Physics Conference Series, 2021 Abstract The study aims to determine the effects of giving several types of manures on various chili pepper varieties. The experiment is a factorial experiment using a randomized block design (RBD) consisting of two treatment factors, namely type of manure (R) of 3 levels: R1 = Chicken Manure, R2 = Cow Manure, R3 = Rabbit Manure and type of varieties (V) of 4 levels: V1 = Genie varieties, V2 = Dewata varieties, V3 = Sigantung varieties, V4 = Gendut varieties. The interaction of varieties and type of manure as a very significant effect on the number of leaves and root fresh weight and significant effect on fresh weight and oven-dry leaves. The highest fresh weight and oven-dry weight was obtained in the interaction of Genie varieties with cow manure, namely 10.06 g and 1.68 g with an increase of 285.44% and 342.10% compared with the interaction of Sigantung varieties with cow manure, namely 2.61g and 0.38 g. The highest fresh root weight was obtained in the interaction of Genie varieties with cow manure, which was 3.09 g or increased 286.25% compared to interaction between Dewata varieties and cow manure, which was 0.80 g. Genie varieties with cow manure types provide better chili seedling growth compared to Dewata varieties and Sigantung varieties.
Utilization of rabbit manure and biochar chicken manure and its effect on the growth and yield of pakchoy plants I M Mesa, Y P Situmeang, A A N M Wirajaya, I G B Udayana, M S Yuliartini Journal of Physics Conference Series, 2021 Abstract This study aims to determine the effect of rabbit manure, biochar from chicken manure, and its interactions on the growth and yield of pakchoy plants. This study uses a randomized block design (RBD) with factorial patterns (2 factors). The first factor is the dose of rabbit manure which consists of 4 levels (0, 10, 20, and 30 tons ha −1 ). The second factor is the biochar dose of chicken manure consisting of 4 levels (0, 5, 10, and 15 tons ha −1 ). The results showed that the treatment of biochar dose of chicken manure and the treatment of interactions between the dose of rabbit manure and the biochar dose of chicken manure had no significant effect on all observed variables. The treatment of rabbit droppings did not significantly affect all observed variables, except that the fresh weight of the roots showed a real effect. Fresh weight of economic results in the application of rabbit manure 30 tons ha −1 , gives a higher yield or an increase of 17.08% when compared to without rabbit manure. While the fresh weight of economic results on the application of biochar from chicken manure 30 tons ha −1 gave higher yields or increased by 23.86% compared to without biochar.
