Abstract

Mild intellectually disabled is an individual who has intelligence far below the average individual in general. Although the intellectually disabled have intelligence that is far below the average, their abilities can be optimized and empowered through learning simple skills that do not require complex thinking or semi-skills. Hydroponic-based animal feed production is an activity in the semi-skills category that has the potential to be used as a medium for learning and empowering the intellectually disabled. This study aims to evaluate the potential of hydroponic-based animal feed production activities as a medium of learning and empowerment to improve the ability and physical suitability of the intellectually disabled. The research method used is field testing and Research and Development (R&D), and data is obtained through observation, interviews, and Focus Group Discussions (FGD). We found that the intellectually disabled can perform stages of work in the manufacture of hydroponic-based animal feed, the introduction of tools and materials, the manufacture of animal feed, the maintenance of tools and materials, and the maintenance of results. The results showed that every step in hydroponic-based animal feed production activities had been implemented and could be used as a medium of learning and empowerment to optimize and empower the intellectually disabled.

Abstract

Bandung Regency has several types of cultivated taro, with the largest production center in the Sumedang District. Semir Taro (TS0) is one of the native commodities in this region, and the other types are from the crossbreeding process between Semir Taro and Thai Silk Taro, which is named Pratama Taro (TS1 & TS2). Although it has been widely marketed and consumed by the public, the nutrient content value of this type of taro is still unknown. In addition, TS1 and TS2 have the potential to be developed into products that have higher economic value if processed optimally. This study contributes to determining the nutritious content of three taro varieties and identifies the most appropriate raw materials for the production of taro-derived products. The methods used were chemical analysis and affective organoleptic tests with paired comparison. Organoleptic tests were carried out on TS1 and TS2, and they were steamed to determine whether there was a difference between the two taros. The results of the test showed that there was no difference in the colour, aroma, and texture parameters of the two taros, but there was a difference in taste between them. While the results of the chemical analysis show that the three types of taros have a reasonably good nutrient content, because the water content is relatively high, there need to be post-harvest management efforts so that taro can be a more durable product for storage.

Abstract

Penelitian ini bertujuan untuk mengevaluasi efektivitas starter organik dalam pembuatan pupuk organik padat dari limbah sayur, daun, kulit kopi, dan limbah rumah tangga. Tiga perlakuan yang diuji adalah tanpa starter, starter DLH, dan starter EM4, untuk memantau perubahan pH, suhu, dekomposisi, serta kualitas fisik dan kimia pupuk. Proses berlangsung selama 21 hari dengan pengukuran setiap 3 hari menggunakan Rancangan Acak Kelompok (RAK). Hasil penelitian menunjukkan bahwa perlakuan dengan EM4 menghasilkan pH dan suhu yang lebih stabil, tekstur halus, aroma tanah yang khas, serta volume pupuk yang lebih stabil dibandingkan perlakuan lainnya. Starter DLH mempercepat dekomposisi namun menunjukkan fluktuasi pH yang lebih signifikan, sementara perlakuan tanpa starter menunjukkan perubahan yang kurang konsisten. Efektivitas starter organik bergantung pada karakteristik bahan organik yang digunakan. Berdasarkan hasil tersebut, penggunaan starter EM4 direkomendasikan untuk menghasilkan pupuk organik berkualitas tinggi yang mendukung praktik pertanian berkelanjutan.

Abstract

This study aims to develop an e-module on organic fertilizer production based on Spent Mushroom Substrate (SMS) with various organic amendments for vocational high school students majoring in agriculture, to support green skills and sustainable waste management. The research began with the process of producing organic fertilizer based on SMS, followed by testing its biological characteristics using Total Plate Count (TPC) test and chemical characteristics using Nitrogen, Phosphorus, Potassium (NPK) tests, followed by the development of an e-module using ADDIE model (Analysis, Design, Development, Implementation, Evaluation), which was followed by expert validation involving subject matter, media, and language experts, as well as trials on 32 tenth-grade students majoring in Agribisnis Tanaman Pangan dan Hortikultura. The results showed that the addition of organic amendments could significantly increase microbial population with TPC test results showing that combination of SMS+floral compost had the most optimal results, namely 20 Cfu/gr×10⁶ on day 7 to 100 Cfu/gr×10⁶ on day 21. The NPK content of SMS-based organic fertilizer was also proven to meet SNI requirements, i.e., 6%/0.06, with SMS+CHMC sample showing the most optimal results in chemical parameters with the highest NPK content. Meanwhile, the results of implementation and paired t-test proved that e-module was considered very feasible, receiving a score of 86.6-96.6% from the validators and effectively improving student understanding, as seen from an increase in the spread of values seen in the boxplot diagram and significance value of the paired sample t-test, which was ≤0.05, taken from the results of students pre-test and post-test.

Abstract

Coffee farmers in Cimenyan Village face significant challenges in the post-harvest drying process due to high rainfall, which reduces quality and lowers income. This research aims to evaluate the performance of an IoT-based coffee-drying system powered by photovoltaic energy, using global solar atlas data. The designed system is a 2 kWp coffee dryer house, which was simulated to assess energy performance, drying efficiency, economic aspects, and environmental impact. The simulation results indicate that the photovoltaic system achieves conversion efficiencies of 80-88% under high irradiance. Drying efficiency reached 54% at an optimal temperature of 50°C, with a specific energy consumption of 0.4-0.6 kWh/kg of water evaporated, which is lower than conventional electric dryers that reach approximately 1.0 kWh/kg. From an economic standpoint, the investment payback period is estimated to be 1.5-3 years with a benefit-cost ratio of 1.4-1.5. Additionally, this system has the potential to reduce CO₂ emissions by 0.5-1.5 tons per year per unit. The system's ability to reduce operational costs, improve product quality, and support sustainable energy transitions in rural Indonesia. Although initial costs and limited technical skills may constrain farmer adoption, cooperative-level implementation, hybrid energy integration, and ongoing training offer promising avenues for future development.   Abstrak Petani kopi di Desa Cimenyan menghadapi tantangan besar dalam proses pengeringan pascapanen akibat tingginya curah hujan, yang menyebabkan penurunan kualitas dan berkurangnya pendapatan.
