Abstract

The One of alternative energy that is environmentally friendly is by untilize water energy and turn it into a Microhydro power plant. Microhydro power plant usually made from utilize the waterfall with the head fell. While utilization for streams with a head small drop is not optimal yet. This is a reference to doing research on harnessing the flow of a river that has a value of head low between 0.7 m – 1.4 m with turning it into a Vortex flow (vortex). The purpose of this research is to know the effect variation number of blade on power and efficiency in the vortex turbine. This research uses experimental methods to find current, voltage, torque and rpm using a reading instrument. The materials research vortex turbine used 6 blade, 8 blade and 10 blade with flat plate. The result showed the highest efficiency is 29,93 % with produce turbine power is 19,58 W, generated on turbine with variation 10 blade with load 3,315 kg and the capacity of water 10,14 l/s. Followed with an efficiency 24,17% and produce turbine power is 15,81 W, generated on turbine with the variation 8 blade with load 3,315 kg and the capacity of water is 10,14 l/s. The the lowest turbine efficiency 22,32% with produce tuebine power 14,60 W, generated on turbine with the variation 6 blade with load 3,315 kg, the capacity of water is 10,14 l/s.

Abstract

This article examines the integration of autonomous fish-feeding systems with salt production and fish processing technologies as an innovative strategy to enhance food self-sufficiency, strengthen rural economies, and promote aquatourism development in Malang Regency, Indonesia. The region possesses significant potential in aquaculture, fisheries, and coastal resource utilization; however, productivity remains constrained by inefficient feeding practices, limited technological adoption, outdated processing methods, and infrastructure disparities. These challenges reduce production efficiency, increase operational costs, and limit the competitiveness of local fishery products in broader markets. The study employs a qualitative and participatory approach based on stakeholder engagement, field observations, focus group discussions, and technological gap analyses involving fish farmers, salt producers, tourism operators, local governments, and community organizations. The research develops an integrated innovation model that combines autonomous fish-feeding systems, smart aquaculture management, sustainable salt production, and value-added fish processing technologies within a unified economic ecosystem. The proposed model is designed to improve production efficiency while creating new tourism attractions centered on fisheries, coastal culture, and environmental education. The findings indicate that the adoption of automated feeding technologies can significantly reduce feed waste, lower operational costs, improve fish growth performance, and enhance overall aquaculture productivity. In addition, integrating fish processing and salt production activities with aquatourism creates diversified income sources, increases employment opportunities, and supports local entrepreneurship. The model also contributes to environmental sustainability by promoting efficient resource utilization and reducing production-related waste. The study concludes that the integration of autonomous aquaculture technologies with fisheries-based tourism represents not only a technological advancement but also a strategic pathway for economic transformation in coastal and rural regions. Furthermore, the proposed framework offers a scalable and replicable model for achieving sustainable food systems, community resilience, and inclusive regional development in Indonesia and other developing countries.
