Abstract

Abstrak Desa Kemujan, yang terletak di Kecamatan Karimunjawa, memiliki potensi besar dalam memanfaatkan limbah sabut kelapa sebagai bahan baku biobriket. Dengan luas wilayah 162,1 km² dan populasi 3.391 jiwa, desa ini memiliki keberagaman budaya dan suku yang kaya. Limbah sabut kelapa yang terdapat di Desa Kemujan pada saat ini belum dimanfaatkan secara optimal. Hal ini terjadi karena minimnya kesadaran dan pengetahuan masyarakat sekitar untuk mengolah sabut kelapa tersebut. Sabut kelapa merupakan biomassa yang dapat dimanfaatkan sebagai bahan alami pembuatan biobriket. Sehingga pengabdian melalui pendampingan dan pelatihan pembuatan biobriket untuk memanfaatkan sumber daya lokal sabut kelapa di Desa Kemujan Karimunjawa perlu diselenggarakan. Metode pelaksanaan yang dilakukan dalam pengabdian ini adalah sosialisasi terkait biobriket dan pelatihan pembuatan biobriket dari sabut kelapa secara langsung. Hasil yang didapat dari pengabdian ini adalah meningkatkan nilai guna dan nilai ekonomis sabut kelapa, berkontribusi pada pengembangan UMKM di Desa Kemujan, serta meningkatkan kesadaran dan pengetahuan masyarakat terkait pemanfaatan limbah sabut kelapa serta proses pembuatan biobriket dari sabut kelapa.

Abstract

Rice bran oil (RBO) is a by-product of rice processing with a good fatty acid profile and high oxidative stability. This study aims to optimize the bleaching stage of the rice bran oil refining process to determine the minimum levels of carotenoids in RBO by using the Response Surface Methodology (RSM). This research used the Central Composite Design (CCD) experimental design with three variables: bleaching temperature (50, 80, 1100C), bleaching time (20, 40, 60 minutes), and activated carbon concentration (0.4, 0.8, 1.2%). As a result, the model was enhanced to explain the correlation of each variable and the different data variations. This study employed the Derringer method to determine the most optimal variable variation that produces the lowest carotene levels. This study found that the optimal carotene level was 4.87 mg/kg with an activated carbon concentration of 1.18%, temperature of 500C, and time of 53.155 minutes.

Abstract

Biscuits are a popular snack due to their practicality, affordability, and potential as a high-nutrition food. However, biscuit production in Indonesia still depends on imported wheat flour, which poses challenges, especially for people with gluten intolerance or wheat allergies. Therefore, the development of local flour alternatives is essential to support food diversification and reduce wheat dependence. Sorghum (Sorghum bicolor (L.) Moench) is a potential local cereal with high carbohydrates and gluten-free properties but contains tannins that can reduce nutritional quality. This study aimed to evaluate the effect of NaOH soaking on reducing tannin content in sorghum flour and its application in biscuit production with soybean flour fortification as a protein source. Sorghum was soaked in NaOH solution (0.1–0.3%) at 30–50°C. Biscuits were formulated with soybean flour substitution levels of 0–50%. The biscuits were analyzed for proximate composition, tannin content, and sensory properties. Data were analyzed using ANOVA test. Results showed that NaOH soaking reduced tannin content up to 72.455 ppm. Soybean flour substitution significantly affected protein, fat, and carbohydrate content (p < 0.05) but not crude fiber. The highest protein content (8.03%) was found in biscuits with 50% soybean flour, while the highest carbohydrate content (64.40%) was in biscuits without soybean flour. Sensory analysis showed no significant difference between biscuit variants (p > 0.05). This study demonstrates the potential of NaOH-modified sorghum flour combined with soybean flour fortification for producing high-nutrition biscuits and supporting local flour diversification in Indonesia.

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

Micro, Small and Medium Enterprises (MSMEs) in Indonesia are the largest business units that support the country's economy. In Mangunharjo District, Tugu District, Semarang City, there are several groups of MSMEs which are mainly engaged in the food processing industry. However, MSME owners face various challenges, such as a lack of marketing methods. As a result, many MSMEs only produce food products when there is an order and rely on consignment at the nearest shop for a limited period of time. This problem requires a solution that can overcome the concerns of MSME owners, one of which is by changing marketing methods. Currently, MSMEs in the regions only rely on traditional marketing methods. By holding training activities for the public about the benefits of digital marketing, it is hoped that MSME owners can change their perspective and adopt more modern marketing methods. Through evaluations carried out after training, the MSME group has started to utilize digital platforms to market their products. The results show that MSMEs are starting to get used to digital marketing to increase sales value.
