ABSTRACT The amount of fuel production that is less than the amount demanded by the world community causes the fuel supply to be expected to run out of stock. Therefore, various efforts were made to save fuel consumption. Not only focus on efforts to discover new and renewable energy, but also focus on efforts to use energy that is efficient. Fuel savings can be done by reducing the weight…
ABSTRACT Broiler chickens will grow optimally if supported by appropriate environmental factors. one of the influencing factors is a comfortable ambient temperature. This temperature can be met by providing a heating device, on the other hand, the use of a heating device will increase the operational costs of maintenance. The purpose of this final project is to obtain a heating device that…

ABSTRACT Welding is an important part of industrial growth because it plays a major role in engineering and production repair. Shield metal arc welding (SMAW) is a welding technique using an electric current that forms an arc of current and a webbed electrode. In the SMAW welding process, there are variables that determine the quality of the welding results, including the selection of elec…
ABSTRACT The friction welding process occurs as a result of the direct conversion of mechanical energy in the form of friction into thermal energy. Thermal in the region near the peak joint has a significant effect on the formation of flash, hot zones and the strength of the rotary friction welded joint. In this study, observations were made on the validation of the thermal distribution wi…
ABSTRACT This study aims to determine the ideal welding speed in electric arc welding with 1G position on ASTM A36 mild steel welding using a Sliding adaptive Two Axis With Speed Control system. Welding is done automatically and the welding speed is adjusted using the Speed Control. For each welding process, the welding speed can be adjusted according to the welding conditions, such as to …
ABSTRACT This study discusses the experimental study of the efficiency of the Organic Rankine Cycle (ORC) system with concave plate collectors as a heat source system. ORC is a conventional rankine cycle modification, where the ORC fluid works is an refrigerant or organic fluid which has a low boiling point, so that to produce steam only requires a low temperature. A good working fluid is …
ABSTRACT Economic growth, population and industrial and technological developments have led to an increase in electricity consumption in Indonesia. As a result, it will threaten the depletion of fossil energi sources. As is known to date, power plants in Indonesia still depend on coal (50%), gas (29%), and oil (7%). So it is necessary to develop renewable energi as a substitute for fossil …
ABSTRACT Energy demand throughout the world is increasing gradually as a result of advances in science and technology. The fossil energy that have been used to met these needs have been decreasing and one day it will definitely run out. The increasing use of fossil fuels results in the production of CO2 emissions which always increase every year. Solar energy is energy that comes from sunl…
ABSTRACT The process of distributing blood from the proper storage before transfusion requires a cooling unit that is able to maintain the temperature so that the blood can be maintained and not damaged before being transfused. To maintain the chemical and structural composition of blood, it is done by storing it at a temperature of 2-6 °C and the distribution is carried at a temperature …
ABSTRACT This final project aims to make the types of impellers where these impellers are used in centrifugal pumps as water turbines. The impeller made consists of three types, namely open impeller, closed impeller, and half-closed impeller, and HUB as a connecting component between impeller and shaft. In centrifugal pumps as water turbines have main components namely water turbines, impe…

ABSTRACT Based on WHO Standards, Indonesia has not sufficient blood supply to a minimum of 258 million people owned. So, when needing certain types of blood that are available outside the area must go through the process of blood distribution. During this time, the distribution only uses ice packs in maintaining blood temperature. The use of ice packs in the distribution process is very ri…
ABSTRACT Electrical energy requirements which continues to increase and diminishing fossil fuels resulting in research in the field of renewable energy developing rapidly, one of the renewable energies is wind turbines. This study aims to determine the performance of the horizontal axis wind turbine by using the type of blade inversed taper NACA 4412 with a composite empty palm fruit bunch…
ABSTRACT One of the steps to save fuel oil that can be done is to design and make energy-efficient cars, namely cars that are able to travel as far as possible with the lowest possible fuel consumption. In the Department of Mechanical Engineering, Riau University, the manufacture of energy-efficient cars has been carried out from 2017 to 2020. One of the cars that has been successfully des…
