Abstract

Indonesia as an agricultural country has great potential in processing agricultural products. However, most agricultural products are still processed into raw products with low economic value. Traditional processing of agricultural products into home industry products is inefficient, resulting in a lot of wasted crops. The solution to increase efficiency is to apply appropriate technology based on solar energy. Solar energy, as an environmentally friendly renewable energy source, can reduce the use of fossil fuels and greenhouse gas emissions, while increasing community income. The service shows that the application of appropriate technology for processing agricultural products into various solar energy-based home industry products is more efficient and meets quality standards. The benefits include economic improvement, environmental sustainability, and productivity optimization. The implementation method involves seven stages of community development from awareness to technology maintenance and development.

Abstract

Electromyography (EMG) is one of the most essential bio signals for developing human–machine interfaces capable of translating muscle activity into motion commands, particularly in prosthetic and assistive robotic systems. However, the nonlinear characteristics of EMG, its susceptibility to noise, and its strong dependence on electrode placement make gesture classification a challenging task. This study aims to classify EMG signals for robotic hand control using a deep learning approach based on Convolutional Neural Networks (CNNs). The dataset consisted of 11,678 samples recorded from eight EMG channels across four hand gestures, preprocessed using a Butterworth filter and normalization prior to training with a lightweight CNN architecture. The model performance was evaluated using accuracy, precision, recall, and F1-score. The proposed model achieved an accuracy of 93%, outperforming Support Vector Machines (SVM), k-nearest neighbors (k-NN), and random forests under identical experimental conditions. The novelty of this study lies in the application of an efficient CNN architecture capable of extracting spatial–temporal features end-to-end from raw EMG signals for real-time robotic control. Despite its promising results, this study is limited to four gesture classes and is sensitive to electrode placement variability. These findings provide a foundational contribution to the development of more responsive, adaptive, and easily deployable prosthetic and robotic control systems.

Abstract

The coastal community of Laikang Village, Takalar Regency, particularly the Pandala Berkah Seaweed Cultivators Group, faces serious challenges in the post-harvest stage. The conventional sun-drying method causes significant product quality degradation, especially during rainy seasons—with drying delays of up to 3–4 days causing discoloration, mold growth, and quality decline. As a result, selling prices of dried seaweed are only IDR 7,000–8,000/kg, far below the industrial market price of IDR 12,000–14,000/kg. This community service activity aims to optimize post-harvest processes through training on the use of a semi-enclosed solar energy dryer (solar dryer) as a blue economy implementation strategy in coastal areas. The implementation method includes socialization through Focus Group Discussion (FGD), technical and managerial training, participatory equipment assembly, and intensive field mentoring. The dryer with a capacity of 30–70 kg per cycle was designed with an indirect heating system based on polycarbonate materials, capable of achieving a stable temperature of 40–55°C without additional heat sources. Results show that 80% of participants understood hygienic drying techniques and temperature control, community participation reached 85%, and a local product identity "Rumput Laut Kering Pandala Berkah" with food-grade packaging was established. This program contributes to increased product added value, drying time efficiency from 2–3 days to 8–10 hours, and supports the blue economy concept based on sustainable coastal community empowerment in alignment with SDG 8 and SDG 14.
