Abstract

Indonesia is one of the largest agricultural countries in the world, with the majority of the population working as farmers. Theagricultural industry certainly needs fertilizer to maintain quality, accelerate growth and provide nutrients for plants to grow well. To provide cheap potassium sulphate fertilizer, we conducted a study on "The Effect of Temperature and Time on Yield andPurity K2SO4Fertilizer from gypsum and Ash Bark" as an alternative to commercially available ZK fertilizers. The reason we usedash bark was because it was a waste from cottonwood industry. This study used a single stage methodwhere in this method the final result was not recycled to save time.The variables used are temperature (60oC, 70oC, 80oC) and time (60, 90, 120 minutes). The results showed that the most K2SO4crystals were formed at 80oC for 120 minutes with potassium concentrations of 69.60%.Keywords: potassium sulphate fertilizer, single

Abstract

Petroleum reserves in Indonesia are running low, as well as fossil energy. If these conditions are not handled appropriately and quickly, the Indonesian nation will experience a petroleum crisis. Biomass briquettes are made from a combination of rice husks, taro husks, and a tapioca flour adhesive, and they will be produced as a byproduct of Indonesia's extensive agricultural sector and the growing taro industry. The use of taro skin in conjunction with other raw materials gives this study an element of originality. The purpose of this research is twofold: to disseminate knowledge about the potential of biomass waste, and to analyze how different biomass waste mixtures affect the briquettes SNI-required properties. An experimental approach was used for this study. In this experiment, three different weight ratios of taro husks to rice husks (KT:50%, KT:75%, and KT:100%) were employed as the primary raw materials. Five-and-a-half percent of the briquette dough's overall weight comes from tapioca flour's role as an adhesive. Preparation of briquette materials, carbonization, briquetting, and testing for biomass briquette characteristics are the first steps in the study approach. The calorific value, moisture, ash, volatile matter, binding carbon, and density tests are all part of this battery of analyses. The highest grade briquettes have a calorific value of 3,993.92 cal/g and are made from 100% KT briquettes. KT briquettes with a 75% moisture content are the highest grade briquettes available. At 22.90%, KT briquettes have the lowest ash level of any high-quality briquettes. Briquettes made from 100 percent KT, or 0.09 percent volatile matter, are the highest grade available. KT briquettes, which have a bonded carbon content of 74.59%, are the highest grade option. 50% KT briquettes, with a density of 0.48 g/cm3, are the highest grade briquettes available.

Abstract

Detergents are the most polluting household waste because contain sulfonic surfactants, which are unbiodegradable, so there is a need to innovate environmentally friendly cleaning products. Household waste has become a serious global problem. However, the environmental impact of household waste is in the form of detergent waste, where the use of detergent sometimes exceeds the dosage and causes much more foam. Lerak fruit is a natural ingredient used as a raw material for the detergent. This community service aims to educate people on making environmentally friendly detergent which was held at the Sumedang Logistics Vocational School. This PKM activity was carried out by outreach to 25 teacher and student representatives. The main objective of this community service activity is to provide knowledge and training on environmentally friendly Lerak detergent to encourage the entrepreneurial spirit and skills of teachers and students of the Sumedang Logistics Vocational School. This activity is a real contribution to utilizing natural resources while maintaining environmental health. The detergent manufacturing process involves saponin extraction using a hot water extraction method, followed by formulation using additional ingredients such as organic fragrances.
