Abstract

The Yeh Dikis River in Tabanan Regency Bali has a natural environment which is considered suitable to be used as a tourism destination. The factor that supports the Yeh Dikis River to become a tourism object is the river's potential to generate electricity. In this paper, a particular turbine for micro-hydro power plant is designed. The Yeh Dikis River has a water discharge of 0.381 m3/s with a head value of 8.2 meters, with a potential output power of 18.15 kW. The value of the water discharge and the output power are used to determine the type of turbine used. The computation and simulation showed that the crossflow turbine is suitable for the power plant. The analysis showed that a water discharge of 0.381 m3/s with a penstock diameter of 0.44 meters produces a specific rotational speed of 186 rpm; while a water discharge of 0.381 m3/s with a penstock diameter of 0.55 meters produces a turbine specification rotation speed of 160 rpm. This indicated that the effective head value affects the determination of the penstock diameter and the water velocity. The smaller diameter of the penstock produces, the higher the velocity of the water flow in the pipe. A low effective head will result in a low specific rotational speed. It was found that the optimum turbine power output for a water discharge of 0.381 m3/s with a penstock diameter of 0.44 meters is 18.15 kW. The work of the crossflow turbine is validated using a turbine simulator to determine the rotational speed of the turbine for a particular torque.

Abstract

Indonesia's Nationally Determined Contribution (NDC) targets a 19 to 27% reduction in greenhouse gas (GHG) emissions from the energy sector compared to the business-as-usual scenario. Assuming this target applies uniformly to all provinces in Indonesia, including the power sector, a modeling analysis of Bali's power system is conducted to assess GHG emission reductions. Two scenarios are developed in the Low Emissions Analysis Platform (LEAP) to evaluate the future deployment of Bali's power system. The Business-As-Usual (BaU) scenario serves as the baseline for emission reduction in other scenarios and assumes the development of Bali's power system without emission reduction interventions. The RUPTL scenario assumes the continued development of Bali's power system in line with the electricity development plan document. Results show that the RUPTL scenario achieves a 20.89% reduction in emissions, which fulfills the regional assumption of a 19% NDC target. However, it falls short of achieving the 2030 target of 27% emission reduction.

Abstract

Kayuan Yeh Ha serves as a clean water source located in Ababi Village, Karangasem Regency. The flow from Kayuan Yeh Ha is utilized for both bathing dan consumption by the surrounding residents. Originating from the Yeh Ha spring, Kayuan Yeh Ha is extensively utilized to fulfill the needs of the local community. In order to meet the water requirements of the local populace, a water storage tank with a capacity of 58.74 m3 was initially established to distribute water to 10 households. In the year 2020, a water wheel was employed to power a mechanical pump without electricity to fill the storage tank. After operating for one year, the water wheel experienced shaft damage, necessitating its replacement with a hydraulic ram pump. However, the hydraulic ram pump only utilizes one-fifth of the available water flow, thereby rendering it less effective. Consequently, this research aims to design an electric water pump system powered by a new renewable energy source. The implementation of this electric water pump is expected to enhance the efficiency of filling the storage tank. Based on measurements dan calculations, the micro-hydro power plant system (PLTMH) is estimated to produce a power output of 6kW. Pump selection is determined by electrical power calculations, water discharge, dan pump prices, leading to the adoption of the Pedrollo F50-160B centrifugal pump capable of delivering a water discharge of 56m3/hour at a head of 25 meters. The Pedrollo F50-160 pump utilizes a 3-phase squirrel cage induction motor generating a power output of 5.5kW. Pipe losses dan fittings are also calculated using Pipeflow Expert software, resulting in a water discharge of 31.687 m3/hour. The pump will be operated at maximum capacity for 24 hours, enabling it to deliver a water discharge of 763,620 m3/day, sufficient to meet the clean water needs of 12,277 individuals or 2,455 families. Achieving this water usage target also necessitates piping to households from the storage tank, totaling 35,900 meters in length with an 80mm diameter dan 49,100 meters of 16mm diameter piping. This system is also equipped with a variable frequency drive or inverter device to enhance the efficiency of the electric pump dan reduce starting current surges, simulated for its performance through Simulink software.
