Abstract

The increasing demand for margarine, especially in palm oil producing countries like Indonesia, raises concerns about energy consumption and environmental sustainability. This review discusses the potential of palm fiber, a lignocellulosic byproduct of crude palm oil extraction, as a solid biomass fuel to improve energy efficiency in margarine processing industries. A systematic literature review was conducted by analyzing more than sixty peer reviewed journal articles, technical reports, and case studies to evaluate the feasibility and impact of palm fiber utilization. Based on various studies, palm fiber contains 47.9 percent cellulose, has a calorific value of 17.2 megajoules per kilogram, and shows low ash and moisture content, making it suitable for combustion in industrial boilers. Emission data indicate reductions in carbon dioxide, nitrogen oxides, and sulfur oxides compared to fossil fuels, with potential greenhouse gas savings of 0.098 tons of carbon dioxide per gigajoule and sulfur oxide reductions of up to ninety percent. Economically, palm fiber offers cost savings of up to forty percent, with a levelized cost of energy around six United States dollars per gigajoule and a payback period of less than five years. The application of drying and co firing technologies, supported by policy incentives such as Indonesia’s capital expenditure assistance, could enhance adoption. Research gaps remain in terms of long term boiler corrosion and industrial scale briquetting. Overall, palm fiber supports circular economy practices and aligns with SDG 7, 12, and 13, contributing to cleaner energy transitions in palm oil based food production systems.

Abstract

Bioethanol is an alternative energy to replace fossil fuels from plants. Central Java is the second largest rice producer in the world in Indonesia, with the potential of rice straw waste which can be optimized into bioethanol. Rice straw contains abundant cellulose reaching 32-47%, hemicellulose reaching 19-27%, and lignin reaching 5-24%. Methods for making bioethanol from rice straw include pretreatment, hydrolysis, fermentation, and distillation. Lignin inhibits acid penetration before hydrolysis and microbial growth during fermentation, so it needs to be eliminated using alkaline pretreatment. Glucose production from alkali-pretreated rice straw can be hydrolyzed using chemical or enzymatic catalysts. Acid hydrolysis method using dilute H2SO4 with consideration of a shorter operating time. In addition, the price of enzymes is very high, and the operating time is very long, which will reduce product effectiveness. The acid hydrolysis method using 2% H2SO4 takes 30 minutes at 150 oC, which can produce a yield of 16%. Production of bioethanol from rice straw using separate hydrolysis and fermentation (SHF) methods. Saccharomyces cerevisiae, with a 24-hour fermentation time, produced a yield of 80.9% and a productivity of 0.172 g/L h. Distillation is used to remove impurities from liquids that have been polluted with rice straw-derived solutes with various boiling points. Vacuum distillation can produce a yield of 40% purity. Utilization of rice straw into bioethanol can reduce environmental pollution so that it supports clean energy.

Abstract

Improper waste management at SDN Petompon 3 Semarang has led to inadequate sanitation and a lack of environmental awareness among students. This community service initiative aimed to address these issues by educating 5th and 6th-grade students on organic waste processing through the utilization of Black Soldier Fly (BSF) larvae. The program introduced a hands-on approach where students learned to sort, manage, and convert organic waste into value-added products such as animal feed and organic fertilizer. Additionally, the program incorporated entrepreneurship training, equipping students with basic skills in packaging, branding, and marketing to promote sustainable small-scale enterprises. The activities included stakeholder coordination, infrastructure preparation, environmental education, and product processing workshops. Results showed improved student participation, increased environmental knowledge, and measurable growth in maggot biomass and waste decomposition rates over 30 days. This integrated program not only enhanced environmental cleanliness at the school but also fostered early environmental stewardship and entrepreneurial skills among students, contributing to sustainable waste management and community empowerment.

Abstract

This community service program aims to optimize the use of Carica (Carica pubescens) waste into liquid organic fertilizer through bioconversion techniques, while simultaneously increasing the capacity of MSMEs and farmer groups in Kejajar District, Wonosobo. Activities include outreach, training, and mentoring in the production of liquid organic fertilizer on a household scale using simple technology based on decomposer microbes. The results of the community service show an increase in partners' knowledge and skills in Carica waste fermentation techniques, as well as in the production of liquid organic fertilizer with physical, chemical, and microbiological properties suitable for organic farming. Analysis shows decrease in pH and color changes, a distinctive fermentation odor, and increases in nutrient content (N, P, K), along with variations in substrate concentration. In addition, participants received mentoring on digital marketing strategies to increase the product's economic value. This program contributes to reducing Carica industrial waste, providing alternative organic fertilizers, and empowering local communities to improve welfare based on regional potential.
