Abstract

Repok Pidendang Hamlet is one of the hamlets in the Pemepek Village area, Pringgarata District, Central Lombok Regency which has a superior agricultural commodity, one of which is the taro plant. An important problem faced by the people of Repok Pindendang Hamlet is the abundant taro harvest but still lacks in processing, causing taro to spoil quickly. Therefore, it is necessary to process taro that can increase the shelf life and quality of taro. This study aims to analyze the energy balance in the drying process of taro tubers (Colocasia esculenta (L.)) in a rack-type dryer. The method used is an experimental method using an energy equilibrium approach. The material used is taro tubers with a thickness of I mm which will be dried with temperature variations of 40-45°C, 50-55°C and 60-65°C until the moisture content is constant. The results show the amount of heat energy in, useful heat energy, outgoing heat energy, lost heat energy, and the highest number of enthalpy were obtained at 60-65°C temperature treatment, which were 1719.72 kJ, 869.59 kJ, 823.98 kJ, 1693.57 kJ, and 304.82 kJ/kg, respectively. The total efficiency of the drying system during drying using rack-type dryers was obtained at a temperature of 60-65°C of 50.56% and the lowest efficiency was found at a temperature of 50-55°C of 24.26%.

Abstract

Karang Sidemen Village, located in North Batukliang District, Central Lombok Regency, has significant potential as a center for high-quality coffee production in Lombok. The village directly borders several forest areas, including Tahura Nuraksa, Community Forest (HKm), Hortipark, and the Rarung Special Purpose Forest Area (KHDK). This availability of resources has led 75% of the community to manage a highly regarded and popular commodity, namely Robusta coffee. Numerous Women’s Farmer Groups and MSMEs manage coffee as a flagship product. Additionally, the village has several attractive locations as tourist destinations. However, this potential has not been fully optimized due to a lack of knowledge and education among farmers and the local community. One factor affecting coffee quality is the equipment and machinery used in the production process. Farmers’ knowledge in operating equipment, maintenance, and proper safety techniques is still not optimal. This is evidenced by the many machines and equipment that are not used in production houses. To address this condition, initiatives are needed to conduct outreach and mentoring activities from academics and practitioners that are inclusive, embracing the entire community. Through outreach sessions, farmers and the local community will be given a deep understanding of the technical operation of coffee processing equipment and machinery. Maintenance techniques and usage according to standard procedures will also be covered. Practical training sessions will enable farmers to improve their skills, ensuring that each stage of equipment and machinery use is carried out correctly, systematically, and with an understanding of basic Occupational Health and Safety (OHS) concepts. By applying the best practices obtained through these outreach and training sessions, farmer groups in Karang Sidemen Village are expected to further improve the quality and quantity of production. This will not only provide direct benefits to farmers but also enhance the competitiveness of the village’s coffee products in both local and international markets. With the support and revitalization of existing equipment and machinery, the local community is expected to become agents of change to achieve higher quality standards, realizing the potential of Karang Sidemen Village’s local coffee.

Abstract

Akuaponik merupakan sistem pertanian terintegrasi, yang menggabungkan akuakultur dan hidroponik dalam sebuah sirkulasi tertutup. Sistem ini memanfaatkan limbah nitrogen dari ikan yang diubah oleh bakteri menjadi unsur hara bagi tanaman, yang pada gilirannya menyaring air untuk dikembalikan ke kolam ikan. Kajian ini bertujuan untuk menganalisis prospek, inovasi terkini, dan tantangan dalam budidaya pertanian secara akuaponik, khususnya dalam aspek kinerja biologis, integrasi teknologi, dan kelayakan ekonomi. Metode yang digunakan adalah kajian komprehensif terhadap berbagai hasil penelitian terdahulu yang membahas komponen sistem, pemilihan spesies, manajemen nutrisi, serta implementasi teknologi seperti Internet of Things (IoT). Hasil analisis menunjukkan bahwa integrasi sensor dan mikrokontroler memungkinkan pemantauan dan kontrol parameter kunci (seperti pH, suhu, amonia) secara real-time, yang sangat meningkatkan efisiensi dan stabilitas sistem. Secara biologis, larutan nutrisi dari sistem akuaponik yang diperkaya atau complemented aquaponic (CAP) dapat meningkatkan pertumbuhan tanaman, seperti selada, hingga 39% lebih tinggi dibandingkan dengan sistem hidroponik konvensional, yang diduga akibat adanya senyawa organik dan mikroba yang merangsang pertumbuhan (PGPR). Namun demikian, profitabilitas sangat bergantung pada skala ekonomi dan strategi pemasaran, sedangkan diversifikasi produk olahan seperti fillet juga dapat meningkatkan Return on Investment (ROI). Tantangan utama ke depan adalah pengelolaan nutrisi, khususnya pendaurulangan fosfor dan kalium dari lumpur padat melalui teknologi mineralisasi yang efisien untuk mencapai sistem yang benar-benar berkelanjutan.

Abstract

In Indonesia has a diverse agroecosystem that plays a crucial role as biological and physical capital for sustainable agriculture. Cilembu sweet potato (Ipomoea batatas L.) is a superior commodity with high economic value, characterized by its distinctive sweet taste, caramel aroma, and soft texture. The main challenge in its cultivation is maintaining productivity and organoleptic quality sustainably. This study reviews the literature on legume intercropping strategies (peanuts, soybeans, sengon, lamtoro) to increase productivity, organoleptic quality, and appetite under various soil-climate conditions. One strategy is an intercropping system with nitrogen-fixing legumes, which not only improves sweet potato growth and yield but also improves land use efficiency, soil fertility, and ecosystem sustainability. Organic fertilization integrated with legume residues improves nitrogen and potassium availability, thus supporting sugar accumulation, tuber aroma, and texture. The effectiveness of this system is strongly influenced by agroecosystem suitability, including soil type and texture, elevation, temperature, and rainfall patterns. A site-specific approach is needed to maximize plant interactions, nutrient balance, and organoleptic quality. Standardized productivity and organoleptic quality assessments are essential to ensure that ecological intensification through intercropping and organic fertilization results in a productive, environmentally friendly agricultural system that maintains the unique honey flavor of Cilembu sweet potatoes.
