Abstract

A significant global issue faced by urban areas worldwide is the extensive conversion of agricultural land. In Indonesia, data from the Central Statistics Agency (BPS) in 2021 indicates that the conversion of national rice fields ranges from 60,000 to 80,000 hectares annually. This trend poses a serious threat to the availability of rice and other food sources. Therefore, urban agriculture represents a practical solution for ensuring food availability in a sustainable and independent manner. One applicable technology is the Vertical Hydroponic Farming System. The objectives of this initiative are: (a) to equip teachers with technical skills so they can serve as trainers for their students, and (b) to provide technical support to SMPN 7 Jember, an environmentally friendly school, in its pursuit of achieving Adiwiyata School status at the East Java provincial level by 2024. The methods employed include: (a) delivering theoretical foundations of hydroponic farming systems through traditional lectures, (b) hands-on practice involving the construction of hydroponic installations, seeding and transplanting techniques, maintenance, harvesting, and post-harvest handling, and (c) implementing hydroponic installations and cultivation at SMPN 7 by actively engaging both teachers and students. In conclusion: (a) there was a 110% increase in teachers' knowledge and skills related to hydroponic farming, with evaluation results of the technical guidance averaging 4.9 (very good), and (b) the implementation of hydroponic installations and cultivation at SMPN 7 Jember progressed smoothly, supporting the school in its goal of achieving Adiwiyata School status at the provincial level.

Abstract

Marungga leaves have the potential to be a source of antioxidants, minerals, and carbohydrates. These leaves can be processed into flour for further processing into various products. Marungga leaves must be dried before they can be processed into flour. They are heat-sensitive, so some of their nutritional content will be degraded if dried at high temperatures. A dehumidification system dryer was designed and built to produce low temperature and humidity to overcome the problem of high-temperature drying. The purpose of this study was to evaluate the performance of the dehumidification dryer and to assess the quality of dried Marungga flour. Drying was carried out under normal working conditions for 8 hours, with air temperature and humidity monitored at 20-minute intervals. The dried Marungga leaves were milled into flour and analyzed for physicochemical properties. The test results yielded the following data: air flow rate 0.109 kg/s, drying temperature 33.5°C, relative humidity 54.7%, drying rate 0.732 kg H2O/hour, specific humidity drop 0.01703 kg H2O/kgda, Carnot COP 6.8, actual COP 4.2, efficiency 61.8 %, SMER 0.055 kg/kWh. The Marungga flour produced had a moisture content 6.4%, protein 36.86%, antioxidants 58.765%, vitamin C 50.338%, and green color (a = -12.75) meets SNI 9228: 2023

Abstract

Penerapan Good Manufacturing Practice (GMP) dalam proses produksi minuman herbal seperti jus sari mengkudu merupakan prasyarat penting dalam menjamin mutu, keamanan, dan daya saing produk di pasar. Kegiatan pengabdian ini bertujuan untuk memberikan pelatihan dan pendampingan kepada UD. ZAM dalam produksi jus sari mengkudu agar mampu menerapkan prinsip-prinsip GMP secara konsisten. Metode yang digunakan adalah pelatihan partisipatif, demonstrasi langsung, dan evaluasi kelayakan sarana produksi yang dilaksanakan di UD. ZAM Kabupaten Jember. Hasil kegiatan menunjukkan (a) Tingkat keidaksesuaian penyimpangan diketagorikan bahwa UD. ZAM berada pada Tingkat Level II. Artinya tingkat penerapan CPPB-IRT (Cara Pengolahan Pangan yang Baik- Industri Rumah Tangga) yang cukup baik, (b) peningkatan pemahaman dan praktik sanitasi, kebersihan personal, serta dokumentasi proses produksi

Abstract

The drying stage critically determines the quality of Modified Cassava Flour (MOCAF), directly affecting its functional properties. Insufficient moisture removal leads to detrimental effects including structural degradation and microbial proliferation, while over-drying promotes oxidation. Existing drying methods lack precision and reproducibility, underscoring the need for a MOCAF-specific dryer system. The central challenge is to develop a drying method that is both rapid and efficient while simultaneously preserving product quality. This study aimed to design an optimized drying model for micro-, small-, and medium-sized enterprises (MSMEs), leveraging a TRIZ-driven innovation process to enhance MOCAF quality and process efficiency. Applying TRIZ facilitated the systematic identification and resolution of conflicting design parameters (e.g., rapid drying vs. product integrity). A hybrid technology model was then developed—combining infrared heating, forced-air circulation, and LPG combustion. Performance was evaluated in a pilot unit capable of drying 50 kg of wet MOCAF per six-hour batch, under controlled conditions: 76 °C drying temperature, 2.1 m³/min airflow, and 413 g/h LPG consumption. The optimized dryer achieved a water removal rate of 315 g H₂O/hour. Comparative benchmarking against conventional sun and cabinet dryers showed the hybrid system significantly reduced drying time while maintaining superior structural and functional properties. The TRIZ-based, hybrid MOCAF dryer offers a scalable, cost-effective solution tailored to MSMEs. By closing the innovation loop—linking TRIZ principles directly to enhanced performance metrics—this study delivers practical, field-ready technology. Key contributions include the first documented integration of infrared, forced-air, and LPG heating in MOCAF drying, optimized process parameters, and clear industrial applicability.
