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.

Abstract

The transition to a low-carbon electricity system is driving the strategic role of hydropower, both as a manageable renewable generator and as the backbone of system flexibility to accommodate the intermittency of wind and solar energy. In recent years, the evolution of studies is no longer limited to conventional reservoir operations but has expanded to hybrid hydro–wind–photovoltaic systems, pumped hydro energy storage (PHES), hydro–PV–storage, hydro–hydrogen, and multi-energy configurations integrating compressed air energy storage (CAES) and liquid air energy storage (LAES). This review article synthesizes the literature to map recent developments on four main themes: (1) the role of hydropower flexibility in the integration of variable renewable energy (VRE), (2) modeling and optimization of multi-scale operations, (3) capacity design and techno-economic evaluation of storage technologies, and (4) issues of reliability, safety, ecology, and artificial intelligence (AI) for prediction and control. Recent literature indicates that coordinating hydro with wind, solar, and storage can increase renewable energy utilization, reduce curtailment, improve operational stability, and enhance economic benefits, particularly when operating models incorporate spatio-temporal correlations, hydraulic constraints, market mechanisms, and flexibility requirements. Gaps remain in multi-scale integration, the incorporation of ecological indicators into market optimization, standardization of economic evaluations, and field validation of intelligent control strategies.
