Abstract

MSMEs are the driving force of the community's economy and play an important role in the coffee processing sector. Gupait MSMEs still face obstacles in the roasting process, which is done manually using a hand crank, resulting in unstable temperatures and inconsistent roasting quality. This community service program was implemented using the Participatory Action Research (PAR) method through the stages of observation, socialization, design of a temperature-controlled roasting machine, trial assistance, and operational training for partners. The roasting machine developed has a capacity of 5 kg per roasting process and uses an automatic Temperature Control system. The implementation results showed a significant improvement in the quality of the roasting, with a uniformity level of around 85-90% and no burnt coffee beans, based on visual evaluation from field trials. Additionally, production capacity increased from approximately 1 kg to 5 kg (maximum drum capacity). The assistance also improved partners' understanding of equipment use and maintenance. This program had a positive impact on product quality improvement, process efficiency, and the competitiveness of Gupait MSMEs.

Abstract

The Direct On-Line (DOL) process of starting a high-power 3-phase induction motor causes voltage sags in the distribution system that is connected to one point of common coupling (PCC). Voltage sag can cause damage and failure of sensitive loads. This article analyzes and proposes a simulation of voltage sag recovery using a Dynamic Voltage Restorer (DVR) based on an Artificial Neural Network (ANN). ANN is used as a detector and regulator of the voltage compensation value. In this study, a 3-phase induction motor will be connected to a sensitive load, and the DVR will be placed in series with a voltage source or PCC with a sensitive load. The simulation test system uses Simulink-Matlab R2016a with different configurations of induction motor parameters. Based on the simulation results show that the parameters of the 3-phase induction motor cause the depth and duration of the voltage sag. DVR with ANN control can detect and compensate for a voltage sag of 0.5 pu so that the voltage will be normal to 1 pu.

Abstract

This research aims to identify and implement the Line Follower Robot Trainer as an innovative effort to advance Islamic education in facing the Society 5.0 era. The research focuses on SMK NU 1 Karanggeneng, Lamongan, as a case study, where robotic technology is used as a learning tool to integrate Islamic concepts with technological advances. This research proposes the Research and Development (R&D). The results showed that using the Line Follower Robot Trainer significantly improved students' understanding of their technological skills. The survey showed that most students (85%) felt more engaged and excited about learning Islam with the help of the Line Follower Robot Trainer. Students reported higher levels of engagement in learning with the robot, and teachers expressed positive support for using this technology in learning. These positive results reflect the potential of technology in enriching students' experiences in preparing for changes in the evolving Society 5.0 era. This research provides a greater understanding of the role of technology in supporting Islamic education, bridging the gap between tradition and innovation, and bringing Islamic education into an increasingly digitized future. The implications of this research can help Islamic education institutions utilize technology as a powerful tool to spread religious values and prepare students to face an increasingly digitally connected era.

Abstract

TPQ Nurul Huda, located in Mayong Village, Karangbinangun Subdistrict, Lamongan Regency, is a religious educational institution that plays an important role in nurturing the younger generation through social and religious activities. This TPQ faces serious problems related to the availability of clean water. The well water used tends to be cloudy, discoloured, and smelly, causing discomfort for residents in meeting their household needs and worshipping. This community service activity aims to overcome these problems through the application of appropriate technology in the form of water filters. The methods used include surveying water conditions, designing and installing filters, training in operation, and maintenance of equipment, as well as testing and evaluating the filtration results together with the community. The results show a significant improvement in water quality, where water that was originally cloudy, discoloured, and odorous has become clear, odourless, and suitable for daily use. In addition, the community's skills in operating and maintaining the filters have also improved, so that this technology can be utilised independently and sustainably, while also contributing significantly to the comfort of worship and the health of the community.
