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

The conversion of organic waste into renewable solid fuel represents a promising strategy to simultaneously address waste management challenges and local energy demand. This research evaluates the technical performance, energy characteristics, and environmental implications of producing bio-briquettes from mixed organic waste through controlled carbonization and densification. Mixed organic biomass representative of community waste streams was carbonized using an insulated drum retort under controlled temperature conditions, followed by grinding and densification with a starch-based binder and a low-dose potassium nitrate additive. The resulting bio-briquettes were characterized in terms of physical, mechanical, thermal, and combustion properties. In addition, mass and energy balance analyses and a cradle-to-gate life cycle assessment were conducted to evaluate process efficiency and environmental performance. The results demonstrate that carbonization temperature strongly influences char yield and fuel quality, with optimal performance observed at approximately 400 °C. Under these conditions, the bio-briquettes achieved a high calorific value of approximately 24.3 MJ kg⁻¹ (≈ 5,800 kcal kg⁻¹), high density, adequate compressive strength, and stable combustion behavior. The addition of potassium nitrate significantly improved ignition performance when applied at appropriate concentrations. Life cycle assessment results indicate that bio-briquette production from mixed organic waste results in substantially lower greenhouse gas emissions compared with fossil fuels delivering equivalent energy. Overall, this research confirms that bio-briquettes derived from mixed organic waste represent a technically feasible and environmentally sustainable waste-to-energy solution suitable for decentralized, community-based energy systems.

Abstract

Advances in machine vision and deep learning offer a promising solution for automated, non-destructive quality assessment for high-quality coffee. This study evaluated the performance of five YOLOv11 variants (n, s, m, l, and x) for real-time detection of defective coffee beans and identified the most suitable model in terms of detection accuracy and computational efficiency. A conveyor-based machine vision system was developed to acquire top-view images of Robusta coffee beans under controlled illumination. A dataset of 3,500 images was prepared, comprising 3,000 annotated images for training and validation (80:20) and 500 images reserved for blind testing. All defective beans were grouped into a single defect class, and the YOLOv11 variants were evaluated using precision, recall, F1-score, mean Average Precision (mAP) at IoU thresholds of 0.5 and 0.5:0.95, and inference time. All YOLOv11 variants achieved high detection performance, with mAP@0.5 values exceeding 0.98. YOLOv11s showed the best overall balance, achieving the highest recall (0.954), mAP@0.5:0.95 (0.689), and F1-score (0.959), while maintaining low inference time and a compact model size. Larger variants, such as YOLOv11x, achieved slightly higher mAP@0.5 but required substantially greater computational resources, whereas YOLOv11n provided faster inference but lower robustness under stricter localization criteria. Blind testing revealed a performance gap relative to validation results, highlighting remaining challenges in model generalization. Overall, the results confirm the effectiveness of YOLOv11 for coffee bean defect detection and identify YOLOv11s as the most suitable variant for real-time inspection within the defined experimental scope.

Abstract

The increasing challenges faced by cocoa farmers in Kampung Cokelat Senare, particularly the decline in cocoa yields since 2020, have necessitated innovative interventions. This community service initiative focuses on improving cocoa processing techniques through food technology to enhance the quality and safety of locally produced chocolate. Expert involvement facilitates effective knowledge exchange essential for revitalizing the local cocoa industry. The primary objective of this initiative is to educate farmers on modern cocoa processing methods and food safety protocols to improve chocolate quality and promote sustainable production. The methodology includes structured workshops led by experts, including Prof. Wan Rosli Bin Wan Ishak, emphasizing optimized cocoa roasting techniques and hygienic processing practices. These activities are complemented by practical demonstrations and field visits to local cocoa processing facilities, enabling direct application of newly acquired knowledge. The initiative produced several notable outcomes. Farmers demonstrated improved understanding of cocoa roasting parameters, resulting in enhanced chocolate flavor profiles. In addition, improved safety measures during processing contributed to reduced aflatoxin contamination, addressing critical food safety concerns. The interactive workshop format increased participant engagement and encouraged adoption of modern techniques. Survey results indicated a positive change in farmers’ attitudes toward innovation and a commitment to applying these methods. Overall, this initiative has positioned the community toward more sustainable cocoa production, with expected improvements in product quality and economic resilience. The program highlights the importance of education, collaboration, and technology transfer in strengthening local cocoa-based industries.

Abstract

This research aims to increase the effectiveness of adding Potassium Permanganate (KMnO4) as an oxidizer in the process of making bamboo charcoal briquettes. The research methodology includes several stages, starting from preparing bamboo waste raw materials, the carbonization process to produce charcoal, to printing briquettes with varying concentrations of KMnO4 (0, 5, 7.5 and 10%). Tests carried out include analysis of heating value, combustion rate, density, air content, compressive strength, ignition duration and ash content to determine the physical and chemical characteristics of the briquettes. The results showed that the addition of KMnO4 had a significant effect on the parameters tested. A KMnO4 concentration of 10% speeds up the ignition time of briquettes significantly to 15 seconds, but results in a decrease in the highest heating value from 5382 cal/g (at 0%) to 5131 cal/g and an increase in the highest ash content to 16.7 g. Treatment with a concentration of 5% showed the most optimal compressive strength value. The use of KMnO4 is effective in accelerating initial ignition but can reduce several other essential qualities such as heating value and ash content. Determining the right concentration is crucial to producing briquettes with balanced performance.
