Abstract

The Center for Plasma Research (CPR), Diponegoro University, as the institution that drafted SNI 8759:2019, continues to oversee it implementation. In this paper, we report the successful implementation of SNI 8759:2019 at the chili center in Batu Bara. This success is strongly supported by the producer cooperative "Berkah Abadi Jaya". At the end of May 2021 there will be a chili harvest throughout Indonesia. Chili prices in the Batu Bara chili farming area fell sharply. Chili is bought by a wholesaler for Rp. 7,000.00 per kilogram. The cooperative buys from the farmers as much as Rp. 10,000.00/kg and Rp. 10,500.00/kg and save as much as 835 kg. The collaboration between the research team and the “Berkah Abadi Jaya” Cooperative has synergistically succeeded in applying ozone plasma technology for large-scale chili storage during the main harvest. These saved chilies are resold to the market when prices have improved. The application of plasma ozone technology in chili centers through washing fresh chili grade 1 using ozonized water and storing it in a refrigerator at a temperature of 80 C can extend the shelf life of chilies to 2 months. This application has provided a double benefit for farmers when their crops are purchased by cooperatives. In addition, farmers who are members of the cooperative also benefit by reselling chilies that have been stored at a higher price, which is between Rp. 16,000.00 - Rp. 23,000.00. The quality of chili stored with this technology has been previously investigated by the CPR and examined for confirmation for storage in the chili center of Batu Bara Regency.

Abstract

ABSTRACT One of the efforts in managing waste is to carry out environmentally friendly bioconversion with one of the most popular composting is vermicomposting. The use of insects in composting is also one of the new technologies, namely the Black Soldier Fly larvae. The combination of two types of decomposing organisms that are synergistic can increase the effectiveness of the decomposition process. The purpose of this study was to analyze the rate of decomposition of vermigot fertilizer in the treatment of cow manure and banana stem waste by utilizing a combination of BSF larvae and earthworms. This study used a non-factorial randomized block design method with 2 techniques (feeding and without feeding), namely D0 = without decomposers; D1 = earthworm (100%); D2 = BSF larvae (100%); D3 = earthworms: BSF larvae (50% : 50% kg); D4 = earthworms : BSF larvae (25% : 75%); D4 = earthworms: BSF larvae (75% : 25%). The results of this study showed that the pH of the vermigot ranged from neutral to slightly alkaline (6.4 - 7.8) in the non-feeding technique, while the pH of the vermigot in the feeding technique was slightly acidic (5.7 - 5.8). The temperature of the vermigot in the non-feeding and feeding technique is the same, ranging from (26 - 31oC) but in the non-feeding technique the temperature tends to rise until the 5th day and tends to decrease on the 7th day to the 21st day. Meanwhile, the temperature of the vermigot with the feeding technique tends to experience fluctuations.

Abstract

Phosphate (P) nutrient plays a significant role in plant growth and yield. P is an essential element that plays an important role in photosynthesis and root development. Phosphate nutrient availability is deficient in some soil types due to retention, such as in Andisol soil types. High phosphate retention in Andisol soil types causes P nutrients to be unavailable to plants and can reduce crop yields. The availability of P in Andisol soils can be done, among others, by applying phosphate solubilizing microbes. Phosphate solubilizing microorganisms are soil microorganisms consisting of bacteria and fungi that can mineralize organic P, dissolve inorganic P minerals, and store large amounts of P to make it available to plants. This literature review aims to determine the mechanism of phosphate-solubilizing microbes in P dissolution in Andisol soil. The methods used in this systematic review are collecting data through the internet and utilizing recognized sources such as Science Direct, Research Gate, Google Scholar, and Web of Science. Content analysis was performed on the collected data, and the results were organized into thematic categories. Furthermore, the findings are presented descriptively with the help of tables to facilitate understanding. Since phosphate-solubilizing microorganisms can dissolve P in the soil through chemical and biological mechanisms, it can be concluded that phosphate-solubilizing microorganisms also have an important role in the soil P cycle. The implications of this literature review are to understand the retention of P nutrients in Andisols and how the dissolution mechanism works, as well as the use of microbes as a solution to increase phosphate dissolution so that it is available to plants.

Abstract

This paper provides a review of the Toba highland peatlands, focusing on their characteristics, environmental impacts and historical significance. The Toba area was influenced by a super volcano eruption around 74,000 years ago, which resulted in global cooling and the deposition of pyroclastic materials known as the Youngest Toba Tuff. The peatlands in the region formed south of the caldera and are characterised by varying extents and thicknesses. Radiocarbon dating indicates that the peat in Toba highland is approximately 20,000-30,000 years old, making it a valuable carbon stock and a record of the past. However, the drainage of peatlands has led to significant environmental degradation. It has resulted in increased CO2 emissions, reduced water supply for local farmers, loss of biodiversity, air pollution from open fire burning practices, and an increased fire hazard. Understanding the environmental impacts and historical significance of Toba highland peatlands is crucial for conservation efforts and sustainable land management practices.
