Abstract

The long-term goal of this study is to get results in the form of cheap, effective, natural, and environmentally friendly thermal energy (thermal) insulators to support the concept of a Green and Sustainable Energy System. The specific purpose of this research is to make partition board specimens made of corn cobs (Zea mays L) by using adhesives from natural materials and testing material according to test standards.The research method was carried out through the process of destroying corn cobs, then filtered with M-50, M-80, and M-100 (Mesh) sizes. Mixing adhesive composition 1:2 & 1:4 for Kanji flour and adhesive composition of 1:1.5 & 1:2 with an Epoxy. Then Conductivity Test is carried out on the Test Box with observation time every 2 minutes.The best data were obtained for mixing Kanji glue, on Mesh 100 - (1:2) surface cross-section pressure of 10 kg with conductivity value = 0.01018257 J / ms, and Epoxy Glue mixture, on Mesh 100 - (1:2) surface cross-section pressure 20 kg with Conductivity value = 0.010614466 J / ms.

Abstract

Electricity availability is essential for improving quality of life in rural areas, particularly in remote regions of eastern Indonesia that lack access to the national power grid due to limited energy supply, transportation constraints, and weather conditions. To address this challenge, this study develops and tests a pico-hydro power system using a vertical-shaft propeller turbine capable of operating under low water flow conditions. The research was conducted in Tetey Village, North Minahasa Regency, utilizing irrigation canal water from rice fields. Direct experimental testing was applied to evaluate turbine performance under varying parameters, including blade type (plate and standard), blade angles of 30° and 40°, a water fall height of 50 cm, and a flow velocity of 0.68 m/s. The results show that the maximum turbine power of 200 W was achieved at 1800 rpm with a torque of 1.5 Nm using a standard four-blade turbine with a 30° blade angle and a water discharge of 0.065 m³/s. Overall, flow rate, fall height, blade type, and blade angle significantly affect turbine performance, demonstrating the potential of pico-hydro systems as an environmentally friendly electricity solution for rural areas with limited water flow.
