ABSTRACT The problem of waste in Indonesia, especially plastic waste, is still unresolved. One alternative solution for dealing with plastic waste today is to convert the plastic waste into fuel oil. The things studied included the physical and chemical properties of pyrolysis oil. The physical properties studied included viscosity and density, while the chemical properties were the heating va…
ABSTRACT A food spinner is a machine that functions as a food slicer from the fluid content contained in food. The fluid in question is water or oil. This final project aims to modify the spinner machine that has been made, both from increasing the volume that can be accommodated, adding components, increasing the power of the electric motor, as well as repairing the frame which previously exp…

ABSTRACT Sacrifice is an activity carried out on Eid al-Adha and in the activity of slaughtering sacrificial animals it is prescribed for people who are able to carry out this worship. The process of slaughtering sacrificial animals in Riau Province, especially in the city of Pekanbaru, often experiences problems because there are many accidents during the process of slaughtering sacrificial an…
ABSTRACT To improve the performance of fixed wing flying vehicles, in 2022 the Mechanical Engineering flying robot team of Riau University redesigned the SA-1300 flying vehicle. The design process of the SA1300 ride has been completed at the design stage. The second stage of the design of the SA1300 ride is the manufacture and assembly of the SA-1300 flying vehicle based on a predetermined des…

One of the main obstacles for developers and users of photovoltaic (Photovoltaic/PV) modules is that the module temperature is too high due to high solar radiation and higher ambient temperature, which reduces PV efficiency. Photovoltaic/Thermal (PV/T) is a hybrid system by combining Photovoltaic with Solar Thermal Collector (STC) to provide electricity and heat simultaneously so as to max…
ABSTRAK In everyday life, many used aluminum cans that are found around us become waste that can interfere with environmental hygiene and it turns out that so far it has not been processed properly by recycling. This is because the largest canned beverage producer in Indonesia is currently lacking in canned waste treatment systems. This final project aims to press used beverage cans with a can…
Abstract At this time the development of the combustion engine is moving towards an environmentally friendly combustion engine which emphasizes the use of lower costs. This is due to the depletion of fossil fuel supplies available in the world. Based on this thought, the developer of a combustion engine that uses fuel that is low in cost and relatively harmless to the environment is carried ou…

ABSTRACT Areca nut is one type of plant that has many benefits for the community. In addition to being sold to collectors, areca nut can be processed into various types of food and drinks so that the benefits contained in areca nut can be felt by many people. One of the areas in Riau Province which is a producer of areca nut is Tembilahan Regency, especially in Keritang District, but in the pr…
ABSTRACK Excavator is a heavy equipment used to move material from one place to another. Excavators are widely used in various fields, namely: construction, mining, infrastructure and so on. Riau University has produced a mini excavator model design at the Hydraulic and Pneumatic Laboratory of Mechanical Engineering, Faculty of Engineering using a pneumatic system based on a traveling unit (un…
ABSTRACT Basically, people still use cooking oil repeatedly and the draining of cooking oil is not optimal. So that many people consume processed foods from frying that still contain or leave oil in the food. The purpose of this study was to analyze the Spinner model using the Analytical Hierarchy Process (AHP) method. AHP makes broad and unstructured problems into a flexible and easy-to-under…
ABSTRACT Friction welding is a method of joining materials caused by friction between two materials which utilizes the heat of friction between the two materials, the same or different. This study aims to determine the effect of rotational speed on dissimilar materials on the weld area and hardness values. There are various methods to overcome problems in the process of joining the material, i…
ABSTRACT One of the materials that is widely used in industrial products is mild steel AISI 1037, but the connection of mild steel has problems using the liquid welding method, so the friction welding method is used. The friction welding used is vertical bar-plate Rotary friction welding, which is the design of Utamar, F. and Siswanto (2014), when testing all specimens, the parameter variation…
ABSTRACT In the industrial world, the use of network pipes is one element that plays an important role, namely as a production chain. Failures that usually occur in steel pipe structures that are buried in the ground or in the sea usually occur due to corrosion attacks, pressure forces from outside. Plastic pipes as a product have been widely used and used for a long time. This study aims …
ABSTRACK Polyethylene is a product that is widely used and used for a long time. One type, namely HDPE (High Density Polyethylene) is formed into a composite material, by adding reinforcement in the form of short fiberglass and long fiberglass. The composites were subjected to an Impact test to determine the impact strength and to analyze the impact strength and the influence of fiberglass on …
ABSTRACT Petroleum is the main source of energy and a source of foreign exchange for the country. However, Indonesia's oil reserves are limited, so alternative fuels are needed. Biodiesel is an alternative fuel to replace diesel which is produced from vegetable oil through a transesterification reaction process between vegetable oil, methanol and a catalyst. However, in its use in diesel engin…
