Abstract

Coffee drying is a crucial stage that influences the final product's quality and flavor. This process must be performed correctly to maintain the quality of the coffee beans and prevent mold growth. This study aims to compare two coffee drying methods, using a Solar Dome Dryer and direct sun drying. The research was conducted in Karang Sidemen Village, Central Lombok, using 100 kg of coffee beans, divided into two groups of 50 kg each for the two drying methods. The results showed that both methods successfully reduced the moisture content to 0%, but the drying with the Solar Dome Dryer was faster (4,320 minutes) compared to direct sun drying (4,380 minutes). The Solar Dome Dryer maintained a more stable temperature (50-60°C) and produced a more consistent drying rate, making it more efficient in preserving the quality of the coffee beans and preventing microbial contamination. This study recommends the use of Solar Dome Dryer for coffee drying in areas with high humidity and variable weather conditions.

Abstract

The environmental conditions of a mushroom house are a crucial factor influencing the growth of straw mushrooms, particularly in terms of temperature and humidity parameters. Therefore, it is essential to continuously monitor the environmental conditions within the mushroom house, specifically temperature and relative humidity (RH). This study aims to design a real-time temperature and humidity monitoring system based on Arduino Uno for use in a straw mushroom house. The research consists of several stages: literature review, design and assembly, programming, testing, and evaluation of testing results using the mean absolute percentage error (MAPE) method. The results show that the developed temperature and humidity monitoring system functions effectively to monitor environmental conditions within the mushroom house. The evaluation of the measurement results using the MAPE method indicates a minimum error rate for temperature and humidity measurements, with a percentage of 2.49% and 9.80%, respectively.

Abstract

This community engagement program aimed to strengthen occupational safety and health (OSH) practices in waste management through the introduction of a large-scale incinerator in Pakuan Village, West Nusa Tenggara, Indonesia. The activity combined direct instruction with the distribution of a practical manual that serves as a long-term operational guide for the community. In addition, the provision of personal protective equipment (PPE) was integrated into the program to enhance the safety of machine operators and reduce potential exposure to hazardous pollutants. The results indicate that participants gained a clearer understanding of incinerator operation, safety protocols, and preventive measures, enabling them to apply waste-to-energy technology more responsibly. Beyond its technical benefits, the program fostered a culture of safety and accountability among local residents, demonstrating the importance of combining training, written guidelines, and protective facilities in sustaining community-based waste management initiatives. This approach highlights the potential of university–community collaboration in promoting environmentally sound and socially responsible waste management practices.

Abstract

Local coffee micro, small, and medium enterprises (MSMEs) in Karang Sidemen Village, Central Lombok Regency, have significant development potential; however, they still face challenges related to marketing practices and limited value addition. Conventional marketing systems restrict market reach and reduce product competitiveness. In the context of the Industrial Revolution 4.0 and Society 5.0, digital marketing offers a strategic opportunity for MSMEs to enhance product promotion and sales performance. This community service program aimed to strengthen the capacity of local coffee MSMEs through the implementation of social media–based digital marketing strategies. A participatory approach was employed, actively involving MSME actors and students through stages of problem identification, program planning, training and hands-on digital marketing practices, and evaluation. The results demonstrated an improvement in participants’ understanding and skills in utilizing social media as a promotional tool, as reflected by the initiative to develop and publish promotional video content for local coffee products, including the flagship Versilia coffee variant. The use of visual content and storytelling facilitated the practical adoption of digital marketing strategies. Overall, this program contributed to shifting marketing behavior from conventional to digital approaches and strengthening the sustainable competitiveness of local coffee MSMEs.

Abstract

This study aims to evaluate the operational performance of a 7000-liter fiberglass biodigester that was revitalized and modified at the Power and Agricultural Machinery Laboratory, Faculty of Food Technology and Agroindustry, University of Mataram. The fiberglass biodigester was developed as an alternative to conventional concrete biodigesters, which are prone to structural damage and exhibit limited operational efficiency, particularly in earthquake-prone regions. The research was conducted as an observational case study through performance monitoring of the biodigester during 40 days of continuous operation following system repair and modification. Cow manure was used as the substrate, mixed with water at a 1:2 ratio (by volume). The monitored parameters included fermentation temperature, substrate pH, gas pressure, daily biogas volume, gas composition, and combustion quality. The results showed that the biodigester operated stably at temperatures ranging from 27 to 31 °C and near-neutral pH conditions, with a maximum daily biogas production of 4.43 m³/day and an average of 1.73 m³/day throughout the monitoring period. The methane content ranged from 52 to 61%, while hydrogen sulfide concentration was reduced to approximately 150 ppm after gas purification, indicating that the biogas was suitable for combustion with a heating value of up to 21 MJ/m³. These findings demonstrate that the fiberglass biodigester exhibits good operational performance and has strong potential for application as a renewable energy system at campus and community scales, supporting sustainable livestock waste management.
