ABSTRACT Piping systems are an essential component in many activities where the main purpose is to transport fluid from one piece of equipment to another. There are many types of fluids that pipes can transport, be it safe fluids or hazardous fluids. Damage to pipelines can be in the form of leaks, blockages, and ruptures causing personal injury, facility damage, environmental damage, and econ…
(1)Potatoes are a type of horticultural crop whose tubers are consumed. Apart from being a substitute for rice, now many potatoes have been processed into various types of food that are more attractive and have high economic value. (2)One of them is stick-shaped french fries, or better known as french fries. (3)This French fries cutting machine is designed to improve the quality and capacity of…

Technological advancements, particularly in the design of electric motors, have paved the way for the development of electric vehicles in Indonesia. Competitions such as the Indonesian Electric Car Contest (KMLI) and the Formula Electric Student Competition at the Indonesia International Motor Show (FESC IIMS) have demonstrated progress in the adoption of this technology. The primary focus of t…
At present, there are many applications that facilitate users in analyzing problems, especially in the field of engineering, such as Inventor, Solidworks, Abaqus, and so on. However, these commercial applications come with a relatively high cost, heavy software size, and strict licensing rules. This, of course, raises concerns for users, especially mechanical engineering students at the Univers…
Every machine element that moves and comes into contact will experience failure. This is due to contact between two objects or friction. In other words, friction will definitely occur when objects move and contact each other. This friction that occurs can cause damage or loss of particles from a material, which is called wear. Wear occurs when two objects press and rub against each other. To pr…
Countermeasures conventional plastic waste which does not naturally decompose faces various environmental problems, such as environmental pollution, and sources disease, so needed alternative material plastic environmental friendly (biodegradable) and easily decompose naturally. One of material biodegradable materials was obtained from starch plants and pineapple leaf fiber cellulose. This rese…
This study aims to determine the effect of friction time variations on dissimilar material welding joints and hardness values. The method used is the friction welding method. One material that is widely used in industrial products is mild steel AISI 1037 and stainless steel 304. One of the tools used is the Rotary upright bar-plate friction welding machine. The parameters used are variations in…
Wheelchairs are mobility devices that are often used by people who have difficulty walking using their legs, due to illness, injury, or disability. Ideally, a wheelchair is needed so that the user feels free and comfortable in adjusting the movement of the wheelchair according to their wishes. In fact, this cannot be done by users who have limitations on the hands, so they need other people to …
The piping system is an important feature in the industrial world, because it has an effective and efficient transportation function for shipping liquids and gases. Prevention of damage, whether leaks or blockages, is very important because it can reduce the number of losses both to the economy, the natural environment, and even loss of life. In this research, a method was developed to detect d…
Welding is a process of joining two metals with or without the process of melting the base metal. There are several types of metal that are commonly used in welding, one of which is stainless steel. The aim of this research is to determine the effect of forging pressure on the welding time of the joint in the interface area and the hardness value in the welded joint of 304 stainless steel mater…
Palm oil is one of Indonesia's foreign exchange earning export commodities. This condition has an impact on increasing palm oil production. Increasing palm oil processing causes the waste produced to increase. One of the wastes from the palm oil processing process is palm ash. The silica content in palm ash has the potential to be an alternative source of silica material to replace commercial s…
Based on the implementation of the national unmanned fast boat contest (KKCTBN), the placement of the propeller shaft tilt angle and the number of propeller blades is one of the main factors in the success of the ship's propulsion system. Therefore, it is necessary to conduct research on the effect of the propeller shaft tilt angle and the number of propeller blades on the performance of the pr…
Manufacturing a propeller with investment casting consumes times due to the wax pattern molding process. Replacing the pattern material to polylactic acid (PLA) would improve process efficiency. This material can be printed with a 3D printer with results that are close to the size of the final product. This allows to cut the wax pattern molding process. This research aimed to make a propeller u…
A battery is a device for storing energy and releasing it in the form of electric power. It plays an important role in the operation of electric cars. The use of battery packs has been widely used as a component of electrical machines in various fields, such as in electric vehicles. This is due to the battery's ability to have high energy density, long cycle life, and so on. Heat dissipation is…

Oil palm plantations in Riau Province are oil palm plantations with the largest land area in Indonesia. One of the areas in Riau Province where oil palm plantation farmers are located is in Kampar Regency, especially in Tapung Hilir District. In the process of shaving oil palm leaves, the craftsmen still use the manual method, namely by cutting the leaves to leave a stick using a knife. To be a…
Excavator is one of the heavy equipment consisting of undercarriage equipped with arm, bucket, and boom. The manufacture of Riau University laboratory scale excavators was first carried out by previous research in 2004. Where an excavator was created with a pneumatic arm whose movement was still maximum and minimum. Other excavator developments in the study developed swing and undercarriage par…
