ABSTRACT In designing a car to be safe to drive, many factors must be considered, one of which is the design of the structure itself. In this study, the frame design was made with two frame models. to consider the best frame model of the two. Next is the evaluation of the framework model with a decision matrix. After getting the right frame model concept, an analysis was carried out by per…
ABSTRACT The background of this research is based on the amount of waste of oil palm empty fruit bunch (OPEFB) in Riau Province which has the potential to be used as composite reinforcement. The problem in the previous research was the weak interfacial bond resulting in low mechanical properties. To increase the interfacial bond between the oil palm empty fruit bunch fiber and the matrix, …
ABSTRACT The problem of meeting the need for clean water has been a challenge in its own right in the last few decades, not only in Indonesia but also around the world. Fulfillment of clean water needs that are not optimal, especially drinking water, causes the community's need for drinking water not to be met. One solution to this problem is to utilize abundant sea water as a source of cl…
ABSTRACT The welding process is used by manufacture field a lot, such as aircrafts, automotives and shipping industries that aims to connect, fill in and cut the metal off. One of the welding process type is called SMAW(Shielded Metal Arc Welding). This type of welding process is the most used by industries because it just need electrical energy as the heat source. The welding process crea…
ABSTRACT The exergy analysis method is intended to overcome the limitations of the first law of thermodynamics in solving energy balance analysis, where the concept of exergy is based on the first and second laws of thermodynamics. Exergy analysis can show the location of energy degradation in a process that can be used to improve the operation or technology of a system. This study aims t…
ABSTRACT Tool path generation is very important to optimal time and cost of the production process of product. This research purpose is to analyze tool path generation and production cost of disc brake for roughing and finishing work on die casting product. This research was used the Taguchi method and simulation using by Software Mastercam 2020 (CNC Milling). The simulation result was obt…
ABSTRACT This study aims to design a biomass stove as a solution for lack of LPG gas in the community in Batu Panjang, Rupat Island, Riau. The Quality Function Deploment (QFD) method is used in this study by elaborating consumer needs through public opinion needs (questionnaire survey) and elaboration of the characteristics of consumer needs. A House of Quality matrix was created to determ…
Abstract Screen printing is a screen printing technique using textile paint as the base material, which can be applied to any desired media. The development of screen printing production, especially in packaging, is increasing, forcing screen printing entrepreneurs to think about how to improve the quality of screen printing results and increase screen printing productivity. The purpose of…
ABSTRACT The fuel energy crisis that occurred at the end of the 20th century and the impact of greenhouse gas emissions began to occur . Therefore, various attempts were made to solve this problem. One way to find a solution is electric cars. One of the components contained in the car is the frame system. Because the weight of the student formula electric car has a large enough effect, it …

Exhaust Fan is a tool that serves to suck gases and dust welds. Gases and dust will be sucked by a rotating fan which will then be issued with through sewer. Exhaust fan made that kind of centrifugal backward inclined type. The manufacture of exhaust fan includes machining process lathe, drilling machine and grafting or assembly using electric welding machine. Main component of exhaust fan is s…
Frying is a cooking process, which is common used to prepare the food by heating the ingredients inside of the pan. To remove the oil after frying process, usually it has been done by manual method and it takes longer time.However, with modification of dryer machine for clothes into frying machine, the cooking process can be beneficial since it works easily and faster. The frying process from m…

The manufacture of threshing station model includes machining process lathe, drilling machine and grafting or assembly using electric welding machine and other supporting equipment tools. Main component…
ABSTRACT This study aims to design the build of a wear test tool or so-called a tribometer that intends to measure the coefficient of friction and wear rate in contact materials in the form of disc-on-disc. This tribometer test tool can be used in dry contact (without any intermediate material between contacts) or wet contact (by using intermediate material between contacts such as lubrica…
ABSTRACT The use of fossil energy sources as fuel is getting bigger along with the increasing need to make reserves of fossil energy sources dwindling. For this reason, the shift from the use of fossil energy to new and renewable energy (EBT) is something that must be done. Renewable energy (EBT) is energy that comes from nature and can be renewed. Biomass is a renewable energy with abunda…
