Recycled waste management, especially in the Giri Mulyo area, is still less than optimal. Giri Mulyo itself is a community village located in Karang Joang village, North Balikpapan sub-district. Most of the residents of Giri Mulyo work as farmers. Based on information from the surrounding community, there has been a decrease in agricultural yields since the covid-19 pandemic. The decrease in income and the increase in the price of fertilizers sold in the market have forced farmers to reduce the amount of fertilizer applied to their agriculture. Based on these problems, an alternative fertilizer that is more friendly to the pockets of farmers in the Giri Mulyo area is needed. So far, many local people have used food waste to make compost as an alternative to fertilizer. However, this method is considered to take a long time and cause unpleasant odors in their environment and also the durability of compost is still quite low. To overcome these problems, the local community needs to be given socialization about information on making organic fertilizer made from household waste, does not require a long time in the manufacturing process and has a high level of product durability. The basic material used is eggshell waste. Organic fertilizer made from eggshell waste contains a high amount of calcium so that it has a good impact on the maintenance of nutrients in the soil, in line with the increase in plant fertility. In addition to being used as a medium for making liquid organic fertilizer, we also provide training in making mosaic pre-works made from eggshell waste to increase the creativity of local residents. The community service activities began with a location survey and interviews with the partners, Giri Mulyo RT 22 residents and teachers of SDN 012 North Balikpapan, which is located in the same location. Next, socialization on recycling eggshell waste into more valuable products was conducted. The activity ended with the residents involved filling out a questionnaire regarding the community satisfaction survey of the activities carried out. The purpose of this activity is to provide knowledge and insight to the community about making liquid organic fertilizer and mosaic artworks from eggshell waste.

Crude palm oil (CPO) is widely used in various processed food products, especially cooking oil. Refining cooking oil involves high heating temperatures and the addition of bleaching earth, which aims to remove the sap and brown-red color. As a result, it can eliminate the carotene, which is not functionally used for good human metabolism. This research aims to remove sap and impurities in CPO by analyzing the optimal operation of heating temperature (60-80 °C) and phosphoric acid concentration (0.5-2 ml) and comparing the functional group change on the degumming process. The analytical method used was Response Surface Technology (RSM) by Central Composite Design (CCD) at Design Expert 12, which used carotene, density, and free fatty acid (FFA) responses. The results are optimal variables on heating temperature 80 °C and 2 ml of phosphoric acid concentration. The result of %FFA in DRPO was 1.917 %, the carotene was 381,350 ppm, and the density was 0.909 g/l. Heating temperature influences the FFA content, which is an important consideration. Higher temperatures can lead to an increase in FFA content. Indeed, lipase activation significantly affects the FFA content by accelerating the enzyme-catalyzed reaction. Apart from that, the addition of phosphoric acid affects the increase in FFA due to the non-reaction of phosphoric acid. The physicochemical characteristics of palm oil after the degumming process have not changed significantly, with the density before and after the degumming process still being in the range of (0.909–0.912) g/l. Group bonds have no change because the C-H and C=O group bonds in the main triglyceride compound. It requires a lot of energy to break the triglyceride cluster chains. The preliminary FFA model was revealed y=0.169\left(T\right)-0.1064\left(V\right)-1.5 to degummed reactor design, further.

Communities around the world are becoming more concerned about the environmental impact of using and heavily relying on fossil fuels, leading to a growing popularity of sustainable energy solutions. Biomass energy has become a popular topic of study around the world due to its sustainability. This study aims to investigate the feasibility of biomass waste valorization through its thermochemical or biochemical conversion into a sustainable, high-value energy commodity, thereby augmenting its economic and environmental value proposition. Hydrothermal liquefaction (HTL) was identified as the most effective method for treating biomass waste. Experiments were carried out by mixing water and biomass waste in a 500 mL autoclave batch reactor at temperatures ranging from 270 °C to 330 °C, with b/w ratios of 1:20, 2:20, and 3:20 and a retention time of 30 minutes. This study was additionally carried out under a starting pressure of 5 bar. Bio-oil had the highest product dispersion (84% at 330°C and a b/w ratio of 3:30). Meanwhile, the biochar yield was less than 10%. The solid product, on the other hand, had GCV values that were about the same as bituminous and sub-bituminous coals, at 6474 and 4888 cal/g, respectively. The carbon content of biochar at 270°C and 330°C is 50.86% and 66.77%, respectively, resulting from a variable b/w ratio of 2:20. GC-MS analyzed the highest-yielding product, bio-oil. The GC-MS study revealed a number of value-added chemicals resulting from the breakdown of hemicellulose, cellulose, and lignin compounds.

Refuse-Derived Fuel (RDF) is increasingly acknowledged as a sustainable method of managing municipal solid waste while simultaneously producing valuable energy. However, the quality and compactness of RDF as a fuel can vary substantially depending on the materials used to produce it. The incorporation of biomass waste and calcium oxide (CaO) significantly influences the pelletizing behavior of biopellets by altering their physical and thermal properties, which in turn determines their effectiveness and suitability as a fuel source. In this study, representative RDF pellets were prepared by blending four primary components: wood sawdust, organic waste, plastic waste, and a fixed proportion of CaO. The investigation focused on assessing the effects of varying biomass waste-to-organic waste ratios on the physicochemical characteristics, densification behavior, and proximate properties of typical RDF pellets. The experimental design included biomass-to-organic waste ratios of 1:1, 2:1, 3:1, 4:1, 5:1, and 6:1 while the proportions of plastic (20 wt%) and CaO (5 wt%) were held constant. The findings revealed that optimal RDF performance was achieved at biomass-to-organic waste ratios of 1:1 and 6:1, respectively. The resulting RDF pellets exhibited the following properties: ash content of 7.04 ± 8.78%, moisture content of 8.19 ± 8.82%, volatile matter ranging from 65.11 ± 66.19%, fixed carbon content of 13.95 ± 17.32%, calorific values between 4193 ± 4419 kcal·kg-1, and bulk densities of 0.98 ± 1.18 kg·dm-3. These results highlight the potential of RDF pellets as a promising alternative fuel source for boiler applications.
