Abstract

Community service activities in Putak Village aim to educate and empower farmers and housewives in utilizing plastic bottle waste as a medium for planting hydroboks technology for vegetable crops through a simple hydroponic system (NFT). This program is carried out for five months through the stages of field surveys, counseling, technical training, mentoring, and evaluation. The results of the activity show the effectiveness of the use of plastic waste as an environmentally friendly and sustainable planting medium, helping to reduce the pile of plastic waste while providing urban farming solutions in narrow yards. This training successfully improved the community's knowledge and technical skills about hydrobacca systems, which is evident from the enthusiasm of the participants and their success in growing vegetables independently. In addition, this program has a positive impact on the economy by reducing spending on purchasing vegetables and supporting the consumption of pesticide-free fresh food. The environmental impact is also seen through increasing public awareness in managing plastic waste based on the 3R (Reduce, Reuse, Recycle) principle. The success of this program can be increased through continuous education, such as seminars, plastic waste management innovation competitions, and the creation of educational materials in the form of videos and posters to reach more bans.

Abstract

The development of energy-efficient, mobile dryers using biomass fuel remains a challenge, particularly for rural agricultural applications. This study experimentally evaluates the energy performance of a mobile drying furnace fueled by sawdust, focusing on the effects of fuel feeder rotational speed (25, 30, and 35 rpm). Key performance metrics include temperature distribution, fuel consumption rate, thermal efficiency, and energy balance. The furnace is equipped with a screw conveyor, combustion chamber, and heat exchanger, with temperature monitored via IR thermometers. The highest thermal efficiency of 37.64% was achieved at 25 rpm, with a fuel consumption rate of 4.25 kg/h and total energy output of 110,144 kJ. At 35 rpm, energy output peaked at 188,369.12 kJ, but efficiency declined to 22.41% due to incomplete combustion. All settings-maintained outlet air temperatures between 43.08–46.08°C, suitable for grain drying. Energy balance analysis revealed that 80.92% of total input energy was transferred to the drying chamber at 35 rpm. These findings suggest that moderate feeding speeds (25–30 rpm) offer the best trade-off between efficiency and energy delivery, confirming the potential of mobile, sawdust-fueled systems for sustainable drying in off-grid settings.

Abstract

This research was motivated by the use of a fixed bed furnace. Fixed bed furnaces are less effective because their use is fixed.  The purpose of this research was to design a mobile drying furnace fueled by sawdust biomass.  This research uses an experimental method with 3 stages of design, namely design approach, functional design and structural design. The data obtained were analyzed descriptively. The result of this research is a mobile drying furnace designed consisting of a fuel feeder, fuel channel, hopper, combustion chamber and heat exchanger chamber, chimney and furnace outlet channel and channel after the fan that can function properly. Furnace testing was carried out using sawdust fuel. The resulting feed speed is 10.3 kg/hour, the capacity of the combustion chamber for sawdust is 3.4 kg, the average temperature in the fuel feeder is 40.41 °C, in the combustion chamber 414.57 °C, in the heat exchanger 79.80 °C, in the chimney 104.11 °C, in the furnace outlet channel 62.77 °C, in the channel after the fan 46.08 °C, the sawdust fuel consumption rate was 5.8 kg/hour and the furnace efficiency obtained in the study was 53.90%. The resulting hot air temperature can be used for drying grain.Key words:  design, efficiency furnace, mobile drying furnace, temperature
