Abstract

This activity aims to improve the quality of cocoa beans and promote sustainable local chocolate production through the application of optimized roasting techniques tailored to the characteristics of locally grown tropical cocoa beans. The program was led by Prof. Wan Rosli Bin Wan Ishak from USM, accompanied by Prof. Haslina Ahmad, along with collaborators from the field of Bioactive Materials and Synthesis at UPM. The activities included the delivery of training modules entitled Enhancing Cocoa Bean Quality through Optimized Roasting Techniques for Sustainable Local Chocolate Production, demonstrations of roasting processes involving parameters such as temperature, roasting time, humidity, and variations in roasting schemes, as well as a field visit to the chocolate production house at Kampung Coklat Senare. This visit aimed to provide a deeper understanding of the production workflow, the diversity of local cocoa beans, and opportunities to strengthen supply chains based on locally sourced raw materials. The primary focus of the program was the design of energy-efficient roasting strategies with minimal environmental impact, while preserving bioactive compounds and characteristic cocoa aromas through controlled Maillard reaction pathways. The initiative emphasized technology transfer, community capacity building, and the adoption of sustainable production practices among cocoa-based micro, small, and medium enterprises (MSMEs) in North Lombok. The long-term impact is expected to be reflected in improved processing efficiency, greater utilization of local resources, and more stable income opportunities for cocoa farmers and local MSME actors. The activity was conducted at Kampung Coklat Senare, Genggelang Village, North Lombok, on 21 January 2026, highlighting the importance of international–local partnerships within the context of community engagement in tropical regions.

Abstract

Coffee is one of the most widely traded agricultural commodities globally, generating substantial volumes of by-products and waste streams throughout its processing chain. These by-products including coffee pulp, cascara, mucilage, parchment, silverskin, and spent coffee grounds represent a significant environmental burden when improperly managed, yet simultaneously constitute a rich reservoir of bioactive compounds and valorizable biomass. This manuscript presents a community engagement initiative focused on disseminating and implementing coffee processing technologies that transform waste streams into value-added products, aligned with circular bioeconomy principles. The activity was conducted on 22 April 2026 with participants are small and medium enterprises (SMEs) KWT Kaki Rinjani in Karang Sidemen Village, Central Lombok with the . The session was delivered directly by Prof. Rosnah Shamsudin that introduced aerospace 3.0 the latest small-scale coffee press from UPM. accompanied with theoretical presentation technique drying of coffee, waste treatment and sensory demonstration of functional coffee conducted from Fatepa-Unram. The expected outcomes include enhanced technical and entrepreneurial capacities among SME actors, improved ability to design functional coffee product, and waste treatment of coffee into valuable product. The long-term impact is the creation of a more resilient SMEs ecosystem in Karang Sidemen Village, with a portfolio of functional, high-value coffee products. Furthermore, optimizing the management of production waste is projected to significantly reduce environmental burdens while opening up new income diversification opportunities for the community. Ultimately, the sustainability of this program will strengthen local coffee's position as a leading commodity managed innovatively, efficiently, and environmentally friendly.

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.
