In this research performed with variation diameter runner type curved, with basi…
Excavators are construction machines comprising an Upperstructure, including a cab, boom, arm, and rotating bucket. The Upperstructure is supported by an undercarriage consisting of tracks or wheels. The Hydraulic and Pneumatic Laboratory of the Mechanical Engineering Faculty at the University of Riau has developed an excavator model using a pneumatic system and a 12V battery controlled by a wi…
Currently, the availability of fossil fuels in nature is very limited and new energy alternatives must be found. One of the newest innovations that is being widely developed is electric cars. Riau University also participated in innovation by designing an electric car called Narasinga. After the design is carried out, it is necessary to analyze the performance of this vehicle so that it operate…

Tribology is the science that focuses on friction, wear, and lubrication of surfaces interacting in relative motion. Lubrication is an effective way to minimize friction and wear. To reduce the use of environmentally unfriendly mineral oil-based lubricants, alternative lubricant sources, such as vegetable oils, are being explored. One commonly studied vegetable oil in current research is palm o…
The braking system is one of the crucial components in a vehicle because braking is a vital safety feature of the vehicle. The braking system functions to reduce or slow down the speed and stop the vehicle, as well as to enable the possibility of parking the vehicle on a downward slope. The braking system under investigation is examined in the prototype vehicle called Gardapati, which employs a…
Pada saat mesin beroperasi, elemen-elemen mesin akan saling bersinggungan dan mengalami sebuah kontak dan juga gesekan sesama elemennya, Pada sistem permesinan akan terdapat kontak antara permukaan part, kontak tersebut berupa point contact (kontak titik), dan line contact (kontak garis), dan surface contact (kontak permukaan). Pada saat kontak antar part tersebut dikenakan sebuah gaya mekanik,…
ABSTRACT Bearings are utilized to minimize friction between components during relative motion, aiming to tackle the prominent challenge faced by the industrial sector, which revolves around minimizing or preventing energy losses caused by friction. Friction is commonly defined as the resistive force that arises when two surfaces move in relation to each other. Journal bearings specifically ope…
ABSTRACT Tribology is a scientific field that studies the interaction of surfaces involving friction, wear, and lubrication in relative motion. Lubrication is one effective method to reduce friction and wear. To minimize the use of environmentally negative mineral oil-based lubricant, alternative lubricant sources such as vegetable oils, including palm oil, are utilized. In this research, RBD …
ABSTRACT Tribology is a science that focuses in friction, wear, and lubrication between two asperities undergoing relative motion. Any friction occurred between base body and contacy body may resulting some wear particles that detached from the two asperities. To minimize the wear phenomenon, lubricants must be added between the base body and the contact body. Lubrication in one method tha…

ABSTRACT Vacuum freeze drying is a drying method that is carried out at low temperatures, reducing product damage caused by high temperatures. Rice is very easily damaged and seasonal, so farmers who apply it are recommended that the cultivation technology will produce large quantities of rice at harvest, including the durability of fresh rice grain which is not good at ± 5 days, is easily …
ABSTRACT When designing a car, it is very important to pay attention to the construction and design of the vehicle. This is useful for obtaining user safety and comfort in driving a car. In this study the design of the body of the car is to have Aerodynamic value and Drag Coefficient as small as possible. Coefficient Drag(Cd) which is large in a vehicle has a considerable influence on efficien…
ABSTRACT A camshaft grinding machine is a machine that can modify a standard camshaft to become a racing camshaft with the aim of adding or widening the camshaft, increasing volumetric efficiency and changing the character of a machine, so that the engine produces more power and as needed. The design of this camshaft grinding machine is designed to be able to work with a rotation that is adjus…
ABSTRACT In the SMAW welding process, there are various types of electrodes with various diameter sizes, besides that the process can use various current strengths. All of that is done to adjust the thickness of the plate and the type of steel. The purpose of this research is to influence the DC electric polarity on the variation of electrodes used. The welding process in this study uses ASTM …
ABSTRACT Freeze vacuum drying is one of the most effective drying methods compared to other drying methods, such as sun drying, solar drying and others. where in vacuum freeze drying it can maintain the quality of the product you want to dry, besides that this method is also very effective for drying products that are easily destroyed when exposed to high temperatures. Where the working princi…
