Abstract

Greenhouse effect-based dryers are an efficient and environmentally friendly technological solution to improve the quality and added value of agricultural and fishery products. This research aims to analyze the comparative technical and economic performance of three variations of ventilation chimney designs, namely conventional, thermal, and multidirectional, in their implementation in local communities. Research methods include field experiments to measure technical parameters, such as temperature, humidity, drying time, and airflow speed, and economic analysis to calculate investment costs, payback period, and net profits. The results showed that the thermal chimney provided the best performance with an average temperature of 50°C, drying time of 21 hours, and high airflow efficiency, suitable for rural areas. Multidirectional chimneys are more flexible against unstable wind conditions, making them ideal for coastal areas. This technology is environmentally friendly with a reduction in carbon emissions of up to 1.2 tonnes of CO₂ per year per unit. The novelty of this research lies in the combination of innovative design, in-depth economic analysis, and the application of technology that is adaptive to local needs and challenges, making it relevant and beneficial to society and the environment. In conclusion, a greenhouse effect-based dryer with a ventilation chimney design is a technology that is feasible to apply to increase productivity, environmental sustainability, and the welfare of local communities.

Abstract

Lonuo Village is located in Tilongkabila District, Bone Bolango Regency, Gorontalo. Kasubi crackers are a typical snack produced by one of the Lonuo Bukit Arang Kasubi Crackers UKMs. Kasubi crackers are made from cassava, tapioca flour, baking soda, and brown sugar, while other production requirements are cooking oil, LPG gas, gasoline, firewood, raffia rope, and plastic packaging. Meanwhile, other supporting tools in the kasubi cracker production process are plastic plates, steamer frames, steaming pans, molding tanks, sweet potato grinding machines, and para-paras as attachments for manual drying. The manual drying place used by IKM consists of 3 bamboo-based lamps measuring 7 x 13 meters for the entire cracker drying place. The drying process using bamboo sheets has many disadvantages, including drying time which takes 4 to 5 drying hours in sunny weather, unpredictable weather, less hygienic, and tends to be contaminated with bacteria because the location of the IKM is opposite the location of the Final Processing Site (TPA) for waste disposal. Bone Bolango Regency. The Kasubi Lonuo Bukit Arang cracker IKM was established in 2000 and has been continued by Santian Pillow since 2020. This IKM has more than 6 (six) permanent and non-permanent employees with daily raw material production of 1 () sack of cassava Working time from grating the coconut to drying takes 8 to 9 hours, namely from 08.00 to 15.00 WITA with the resulting cracker output being 2448 crackers per day and packaged in one hanging containing 10 crackers and priced at IDR. 11,000 per hanging. The method used in this activity is the preparation stage, implementation of activities, and program sustainability plans. The alternative drying tool that will be socialized in this activity is a greenhouse drying tool in the form of a rectangular prism with the help of energy from sunlight. While serving this community group, the service team packages activities from lecture presentations on introducing tools, questions, and answers, how to make tools, how to use tools, and how to maintain tools. From the results of this activity, it was agreed that the next activity would focus more on making cracker products using biomass stoves or stoves fueled by used oil and greenhouse effect dryers.
