ABSTRACT This study aims to analyze the roundness of shafts using a Roundness Tester Machine with the assistance of MATLAB to improve measurement efficiency and accuracy. Measurements were performed on a test specimen in the form of an aluminum shaft with a length of 200 mm and a diameter of 24 mm, with data collected at 36 points at 10° intervals. Data were automatically gathered using a dig…
ABSTRACT Monohull-type Platform Supply Vessels (PSVs) play a crucial role in supporting offshore operational activities. Although the monohull hull design provides structural efficiency, these vessels are prone to stability issues and hydrodynamic resistance under dynamic conditions. Therefore, additional components such as turn fins and trim tabs are required to enhance vessel performance. Th…
ABSTRACT Thresher machine is a tool that serves to separate the fruit from the bunch by slamming the fresh fruit bunch (FFB) with the help of rotation on the thresher drum. This tool is in the form of a rotating drum with a speed of ± 22-25 rpm. The thresher drum is 2 meters in diameter and 4 meters long. The process to produce crude palm oil can be said to not be able to take place optimally…

The design is intended to support construction needs, particularly in the development of toll roads in the Riau region, which continues to grow. The methodology used includes manual calculations based on engineering mechanics theory and numerical analysis…
ABSTRACT CV. Musbar Mie is a food industry company located on Jl. Arifin Ahmad Gang Pelangi, focusing on the production of fresh noodles and raw noodles for chicken noodles, with a daily capacity of 700 kg. This study uses the Systematic Layout Planning (SLP) method to analyze the production facility layout and recommends the implementation of the 5S method to improve work productivity. The in…
ABSTRACT This research aims to measure production capacity, design facility layouts, and improve working conditions. Based on calculations, it was found that the daily production capacity of UMKM Bumbu Masak Buya can consistently reach 200 kg by following a structured work schedule. Furthermore, UMKM Bumbu Masak Buya does not yet have an organized production area layout or adequate supporting …
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…
