Abstract

ABSTRACTTofu is one of the vegetable protein sources. Low-temperature is often the best place for food storage. In households, low-temperature storage can be done in the refrigerator. This study was aimed to find out the effect of low temperature storage on protein content and organoleptic properties of tofu and to determine how long tofu should be stored at low temperature to possibly be used as a reference, especially for tofu consumers. This research was conducted using an experimental method with non-factorial Completely Randomized Design (CRD). In this study, tofu was soaked in water and stored in a container then put in a refrigerator (5 – 10 °C) with varied storage period consisting of 4 treatment levels that were without storage (T0), 2-day storage (T1), 4-day storage (T2), and 6-day storage (T3). Protein content was analyzed by using indophenol-blue and organoleptic assessment was done with the hedonic test. Data analysis was conducted using the Analysis of Variance (ANOVA) method. The result of the research shows that low-temprature storage had a significant effect on protein content and the organoleptic properties of tofu. Tofu stored at low temperature can last for up to 2 days with a protein content of 7.55% and organoleptic properties of color, aroma, and appearance reached 4.3 (like), 4.3 (like), and 4.2 (like).Keywords:Low temperature storage, tofu, protein, and organoleptic.ABSTRAKTahu merupakan salah satu sumber protein nabati.

Abstract

The increasing depletion of fossil fuel reserves and rising global energy demand have accelerated the development of renewable energy sources, particularly biomass-based fuels. This study aimed to analyze the effect of biomass weight ratios of patchouli leaf waste and sawdust on the chemical properties and combustion rate of charcoal briquettes, and to determine the optimum composition for producing high-quality briquettes. The research was conducted in Wakumoro Village, Parigi District, Muna Regency, Southeast Sulawesi, from October to November 2025. A Completely Randomized Design (CRD) was applied with five treatment levels and three replications. The treatments consisted of different ratios of patchouli leaves and sawdust: P1 (100% patchouli leaves), P2 (75% + 25%), P3 (50% + 50%), P4 (25% + 75%), and P5 (100% sawdust). The observed parameters included moisture content, ash content, and combustion rate. Data were analyzed using Analysis of Variance (ANOVA) followed by Duncan’s Multiple Range Test (DMRT) at a 95% confidence level. The results showed that biomass composition significantly affected moisture content, ash content, and combustion rate of briquettes. The best overall performance was obtained in P2, with moisture content of 1.57% and ash content of 7.48%, both meeting the Indonesian National Standard (SNI 01-6235-2000). The highest combustion rate was observed in P3 at 6.93 g/min. These findings indicate that the combination of patchouli leaf waste and sawdust has strong potential as an environmentally friendly alternative fuel and provides an effective solution for agricultural and wood waste utilization.

The program was motivated by the high daily fish catch potential of approximately 100-150 kg, while processing activities were still limited to fresh fish sales and dried fish production of around 10 kg per week. In addition, fish bone and head waste of approximately 20-30 kg per day had not been productively utilized. This program aimed to increase production capacity, encourage diversification of processed fish products, utilize fish bone waste into natural flavoring, strengthen business management, and expand marketing through digital marketing. The implementation method consisted of coordination with village government and partners, socialization, technical training, application of appropriate technology, mentoring, monitoring, and evaluation through observation, production logbooks, turnover records, simple pre-tests and post-tests, and participant feedback questionnaires. The results showed an increase in production capacity from approximately 10 kg to 50 kg per week, an average turnover increase of about 30%, the development of diversified products such as fish floss, fish nuggets, and natural flavoring, and the achievement of 30 online and offline transactions during the first three months of mentoring. Fish bone waste that was previously discarded has been utilized at around 15-24 kg per day into economically valuable products. The program indicates that empowerment based on appropriate technology, business management, and digital marketing can strengthen local food security, increase income, and promote a circular economy in coastal communities. Keywords: Fishermen Empowerment; Fish Bone Waste; Natural Flavoring; Digital Marketing; Local Food Security.

Abstract

This study aimed to determine the effect of corn flour (Zea mays L.) substitution on the moisture content and organoleptic characteristics of cookies, including color, aroma, texture, and taste. The study employed an experimental method with a quantitative approach using a Completely Randomized Design (CRD) consisting of four treatments: A0 (0%), A01 (15%), A02 (25%), and A03 (35%), each with three replicates, resulting in 12 experimental units. The cookie production process involved substituting corn flour for wheat flour; moisture content was then analyzed using the oven method, and organoleptic testing was conducted with 15 panelists using a 1–5 hedonic scale. The results indicated that corn flour substitution influenced the moisture content and organoleptic characteristics of the cookies. The highest moisture content was obtained in treatment A0 at 4.56%, while the lowest moisture content was found in treatment A01 at 2.46%. The organoleptic test results showed that treatment A02 received the highest score for color at 3.80, while the highest scores for aroma, texture, and taste were obtained in treatment A0 at 4.00, 3.93, and 4.00, respectively. In general, increasing corn flour substitution caused the color to change to a more yellowish-brown and made the cookies more brittle due to the absence of gluten in corn flour. Based on all test parameters, treatment A02 with 25% corn flour substitution showed the most balanced results and was still acceptable to the panelists. This study indicates that corn flour has the potential to be used as a wheat flour substitute in the development of cookies based on local food ingredients.
