Quality Function Deployment (QFD) is a systematic method used to identify and meet customer needs by integrating the voice of the customer into the product design and development process. The application of QFD in the developm…
ABSTRACT This research aims to analyze the corrosion rate and the efficiency of bay leaf (Eugenia Polyantha L) extract as an inhibitor at concentrations of 0%, 3%, 6%, and 9% on ST-37 steel in a peat water medium. The bay leaf extract was prepared using a maceration method, and the solvent was separated using a rotary evaporator. ST-37 steel specimens, measuring 10 mm × 10 mm × 3 mm, were im…
ABSTRACT The automotive industry sector currently requires materials that have strong and lightweight properties such as composite materials. Composites are the result of combining two or more materials macroscopically which aims to produce materials with superior properties. Therefore, the use of oil palm frond fiber as a composite reinforcement is an environmentally friendly alternative to r…
ABSTRACT Generator sets (gensets) are one of the main sources for generating electrical energy, especially in areas not yet covered by the main electricity grid. Optimal generator set performance depends heavily on the stability and balance of its components. This research aims to design and manufacture generator set supporting components that can improve operational stability, energy efficien…
ABSTRACT Micro, Small, and Medium Enterprises (UMKM) in the culinary sector face challenges in production efficiency due to the limitations of the equipment they use. Many business owners still rely on manual methods or simple machines that are unhygienic, inefficient, and difficult to clean. To address these issues, this final project aims to modify a manual meat grinder into a motorized syst…
ABSTRACT The use of natural fibers as an alternative textile material is growing along with the increasing need for environmentally friendly and sustainable materials. One of the potential natural fibers is pineapple leaf fiber (Ananas comosus), which has a fairly high tensile strength. This study aims to examine the effect of variations in alkalization treatment using sodium hydroxide (NaOH) …
ABSTRACT Pipes are widely used for the transportation of liquids from one place to another, commonly found in domestic and industrial areas. Piping systems are becoming increasingly important for energy supply, economic activities, industry, the social sector, and other aspects of life in most countries because they are widely used for the distribution of water, oil, gas, and others. Pipeline …
ABSTRACT Piping systems are an important element in the distribution of fluids in various industries, such as drinking water, oil, and gas. However, pipes often suffer damage due to natural disasters, corrosion, mechanical failure, or other external factors. This damage can take the form of leaks, blockages, or pipe ruptures, which can cause injury, damage to facilities, environmental pollutio…
ABSTRACT Energy at this time has a very important role in human life. So far, the main support for energy needs still relies on petroleum, while it is inevitable that petroleum is increasingly scarce and expensive. With the depletion of fossil energy sources, in today's world there is a shift from the use of non-renewable energy sources to renewable energy sources. Of the many renewable energy…
ABSTRACT Pipes are an important element of today's infrastructure, serving as the backbone of fluid distribution systems for water, gas, oil, and other fluid resources. In line with industrial developments, methods for detecting pipe leaks have undergone updates. However, some of these methods have shortcomings, particularly in terms of cost and measurement accuracy, necessitating the develo…
ABSTRACT Indonesia is a country located on the equator that has a variety of alternative energy sources, one of which is water that can be used for energy needs in industry, transportation, commercial, and households. Riau is one of the provinces where the streams and waterfalls are still not fully utilized by the community. Micro-hydro power plants (MHPs) are one of the renewable energy …
ABSTRACT Lemang is a traditional Indonesian food cooked by roasting glutinous rice in bamboo over an open fire. The manual roasting process requires a long duration and constant attention to ensure even cooking, often resulting in inefficiencies and uneven doneness. To address these issues, a closed-type rotary lemang roasting machine was designed and developed in this final project. The aim o…
This research aims to design and develop a pesticide sprayer in the form of a trolley sprayer using a 2-stroke engine. This tool is designed to increase the efficiency of pesticide spraying in agricultural areas, especially in hard-to-reach locations. With a capacity of 70 liters, this trolley sprayer is expected to provide a wider spraying area than a hand-held sprayer with a manual lever, whi…
ABSTRACT Excessive use of oil in fried foods can have a negative impact on health, so a tool is needed that can reduce oil levels effectively. This study aims to develop a cooking oil drainer (spinner) with the addition of speed control and time control features (timer), and uses the Analytical Hierarchy Process (AHP) method as the basis for design decision making. The AHP process involved thr…
ABSTRACT The bending process of galvanized pipes often causes cross-sectional deformation, one of which is ovality—a change in the pipe's cross-sectional shape from circular to oval. This deformation can affect the strength and reliability of piping systems. This study aims to analyze the effect of wax filling inside galvanized pipes prior to the bending process on the quality of the bending…
ABSTRACT This research addresses the critical need for boat hull materials capable of withstanding the acidic and chemically aggressive peatwaters prevalent in Riau Province, Indonesia. The study evaluates the impact resistance of composites made from thorny pandan fiber (Pandanus tectorius) embedded in a recycled PET (Polyethylene Terephthalate) matrix derived from used plastic bottles. Thorn…
ABSTRACT Polymer materials commonly used for car bumpers are thermoplastics, because they are lightweight, reduce vehicle weight without sacrificing safety, are able to withstand impacts well, are easy to shape, flexible or not rigid, easy to repair, durable and cheaper. So to get a flexible bumper material, Polyethylene material is used and to increase strength, TKKS fiber is used as a reinfo…
ABSTRACT This study aims to design a screw-driven press tool as an alternative pressing mechanism for the Production Technology Laboratory at Universitas Riau.
