Abstract

The primary goal of this research is to identify and evaluate the most suitable thin-layer drying model to effectively interpret the drying characteristics of banana chips and determine moisture diffusivity at different drying temperatures. The study utilized physiologically mature “kapok” bananas from the local market in Jember Regency. A flash dryer with a 4000-watt electric heating system was used, equipped with a blower for air circulation, an exhaust fan to expel water vapor. The bananas were processed into chips with a thickness of 1 mm. A total of 2000 g of banana chips were dried at constant temperature according to treatment conditions (air velocity 3.2 m/s, drying at temperatures of 60, 70, and 80°C). The study found that higher drying temperatures (80°C) achieved the highest initial drying rate (35.9% in 30 min) compared to 60°C (28.0%) and 70°C (22.0%). However, the drying rate gradually decreased at all temperatures. The drying kinetics of banana chips at 60, 70, and 80°C aligned well with the modified Midilli model. Effective moisture diffusivity values for banana chips at 60, 70, and 80°C were 4.947E-9 m²/s, 5.165(10–9) m²/s, and 5.756(10–9) m²/s, respectively, indicating that drying at 80°C was the most effective. The effective moisture diffusivity value showed a strong correlation with air velocity, drying temperature, material thickness, RH, and specific material attributes. Keywords: Banana, Diffusivity, Drying, Thin layer drying, Modified Midilli Model.

Abstract

Energy shortages remain a major challenge for remote communities, impacting sustainable economic development. Micro-hydropower plants (PLTMH) utilizing flowing water resources offer an efficient and cost-effective renewable energy solution, especially for small-scale electricity needs (<100 kW). a community-based service research project in Bedadung Village, Jember Regency, examined the application of Archimedes screw turbines in PLTMH with variations in the immersion levels of the waterwheel (0.5 and 0.75 of the wheel diameter) and measurements taken at different time intervals. Simulation results showed that a waterwheel immersion of ¾ below the water surface produced an average rotation of 476.27 rpm and a voltage of 12.75 V, which was more optimal for meeting the electricity needs of the local community, particularly in tourist locations and commercial areas. A participatory approach and learning-by-doing methods enhanced community understanding of local resource potential while sustainably building energy and economic self-reliance. This study emphasizes the importance of turbine design adjustments and water resource management for the technical and ecological sustainability of PLTMH in remote areas.

Abstract

Abstrak Tujuan kegiatan pengabdian kepada masyarakat (PKM) yaitu (1) memberikan pengetahuan dan keterampilan PT Rima Kinanti Lestari selaku mitra dan kelompok ternak binaannya dalam mengolah pakan sehingga ketersediaannya dapat terjaga. (2) Mengetahui manfaat penambahan crude tanin kulit kopi pada silase untuk mendukung pertumbuhan ternak potong. Pengabdian masyarakat dilaksanakan pada bulan Agustus-November 2023 dan berlokasi pada kediaman mitra di Bagorejo, Gumukmas, Jember. Kegiatan ini melibatkan mitra dan 25 kelompok ternak binaan. Tahapan pengabdian diantaranya yaitu Focus Group Discoussion (FGD), penyuluhan, pelatihan, serta monitoring dan evaluasi oleh tim pengabdian. Hasil kegiatan PKM  yaitu seluruh target pada setiap tahapan telah terpenuhi. Pendekatan edukatif pengabdian memiliki dampak positif diantaranya meningkatnya pengetahuan mitra dan kelompok ternak binaan terkait teknologi pengawetan hijauan yaitu silase dengan penambahan crude tanin kulit kopi dan manfaat yang ditimbulkan setelah diberikan langsung untuk ternak potong. Setelah kegiatan ini terlaksana diharapkan mitra dapat secara mandiri mengembangkan teknologi silase crude tanin kulit kopi dengan tetap didampingi oleh tim pengabdian. Kata kunci: crude tanin; kulit kopi; silase; ternak potong Abstract The aim of community service activies is to provide knowledge and skills PT Rima Kinanti Lestari as a partner and all livestock group to processing feed so that its availability can be maintained. Furthermore, the benefits of adding crude tannin husk coffee to silage support the growth of livestock. Community service held in August-November 2023 and location at Bagorejo, Gumukmas, Jember. This activity involves partners and 25 livestock group built PT Rima Kinanti Lestari. The stages of service includ Focus Group Discussion (FGD), counseling, training, and monitoring evaluation. The conclusion has been achieved of all activity targets at each stage. The educational approach to service has a positive impact, include to increasing the knowledge of partners and assited livestock group regrading forage preservation technology namely silage with the addition of crude tannin coffe husk and the benefits thaht arise after be given directly to livestock. After this activity is carried out, it is hoped that partners can indpendently develop silage technology crude tannin coffe husk  while still being accompanied by the service team. Keywords: crude tannin; coffee husk; silage; livestock

Abstract

This research aims to identify the characteristics and production of fodder at different harvest times by establishing a hydroponic system to ensure a continuous supply of feed for dairy cows. The study comprises two phases. Phase I examines the production and nutrient quality of hydroponic fodder as a substitute for forage. This phase was conducted experimentally via a 2x3 factorial completely randomized design (CRD) design. Factor I = Plant type (maize and rice). Factor II = harvest time (7 days, 10 days, and 13 days). Phase II involves assessing the palatability of maize and rice plants as hydroponic fodder for dairy cattle. The data were analysed via a 2x2 factorial RAL design. Factor I = Plant type (maize and rice). Factor II = harvest time (10 days and 13 days). Maize and rice fodders harvested at various ages present the following characteristics: 1) As the harvest age increases (7, 10, and 13 days), the protein content of both maize and rice fodder increases, although overall production tends to decline after 10 days. The highest (fresh and DM) production occurs with maize fodder harvested at 10 days. 2) The elevated ADF and NDF contents in rice fodder up to 13 days result in lower dry matter digestibility (DMD) and organic matter digestibility (OMD) compared with those of maize fodder because of the presence of husks, which are the primary source of crude fibre. 3) Maize fodder is preferred by dairy cows owing to the number and size of its leaves and its vibrant green appearance.
