ABSTRACT The need for electrical energy in remote areas is still a challenge, especially due to limited access to conventional electricity networks. One potential and efficient solution is the use of Pump as Turbine (PAT) technology, namely the use of a centrifugal pump in reverse to generate electrical energy from water flow. This study aims to examine the effect of variations in the number o…
ABSTRACT This study aims to modify and analyze the product quality of a horizontal-motion hydraulic pipe bending machine in order to improve the tool’s ability to achieve a bending angle of up to 90°, which was previously unattainable. The modification was carried out by adding an auxiliary tool to the hydraulic pendulum of the jack, with the aim of extending the pendulum stroke without alt…
ABSTRACT This study aims to analyze damage to critical turbine components at the Maninjau Hydroelectric Power Plant (PLTA Maninjau) using the Failure Mode and Effect Analysis (FMEA) and Reliability Centered Maintenance (RCM) methods. As a primary component in hydroelectric power generation, the turbine plays a vital role in maintaining the continuity of electricity production. Despite routine …
ABSTRACT Maninjau Hydroelectric Power Plant (PLTA Maninjau) is a vital energy source in West Sumatra with a total capacity of 70 MW. One of its essential components is the governor machine, which regulates turbine speed and electrical frequency. To reduce downtime caused by unexpected failures, a well-planned maintenance strategy is required. This study applies the Failure Mode and Effect Anal…
ABSTRACT Lubricants are widely used in mechanical systems to reduce energy loss and wear caused by friction. The problem of pollution to the environment caused by lubricants has attracted attention. Biolubricants are an alternative to lubricants that are clean for machines and renewable. To produce biolubricant is by transesterification. In this study, biolubricant was produced by varying the …
ABSTRACT Waste is one of the environmental problems that until now cannot be handled properly, while the ability of waste managers to handle waste is not balanced with its production. Lack of public awareness of the environment means that rubbish is scattered and piled up in various places. The limited number of places to dispose of waste is something that greatly influences the waste problem.…
ABSTRACT Grass management in plantations is carried out to clear the area of the plantation from grass and simplify the process of harvesting the garden area. Making a push lawn mower with a cutting knife height positioner is through production processes such as machining including the lathe process, cutting process, drilling and rolling process. And the machine is planned to be made with seve…

ABSTRACT ABSTRACTABSTRACT This research aims to design and manufacture the body of the Gardapati energy-efficient car in the prototype category, adhering to KMHE 2024 regulations. The vehicle body was designed using CFRP (Carbon Fiber Reinforcement Polymer) to reduce weight and enhance aerodynamic efficiency. Aerodynamic simulations were conducted using Ansys Workbench software to compare the …
ABSTRACT This study analyzes the steering system of the Gardapati energy-efficient car prototype, a three-wheeled vehicle designed in accordance with the 2024 Energy Efficient Car Contest (KMHE) regulations. The main focus is on determining the Ackermann steering angle, analyzing the Linkage and steering column mechanism, and calculating the forces exerted on the steering system under static…
ABSTRACT This study aims to analyze the effect of using acetone, metanol, and water as working fluids in heat pipes on the performance of a Photovoltaic/Thermal (PV/T) system. A PV/T system integrates photovoltaic panels to generate electricity and thermal collectors for water heating, thereby enabling more efficient solar energy utilization. The heat pipe plays a crucial role in enhancing…
ABSTRACT Small-scale hybrid wind turbines are innovations made by combining two different types of wind turbines with the same axis to improve the efficiency performance of the turbine. The object of this research is the design of the aerodynamic design of the venturi wind turbine blade profile resulting from testing the hybrid Horizontal Axis Wind Turbine (HAWT).
