Abstract

Mechanical Engineering Education study program is a study program that produces professional staff in the field of teaching and engineering who have competence in carrying out teaching processes, workshops, manufacturing processes, manufacturing drawing designs, etc. One of the courses in PTM is Computer Aided Design 1. This course is a compulsory subject that must be taken by PTM students in semester 4. The problem that occurs in this research is the implementation of learning in Computer Aided Design 1 courses in study programs The Mechanical Engineering Education of the Sebelas Maret University FKIP has not been maximized, so it is not known the degree of suitability between the implementation of the learning program and the semester learning design and the resulting output. Therefore, appropriate learning tools are needed in the learning process for CAD 2 courses. Testing the feasibility of these learning tools involves 3 parties, namely material experts, media experts, and users. From the assessment of material experts, it was obtained that the percentage of eligibility averaged 81,75% and was included in the "very feasible" category. From the assessment of media experts, it was obtained that the average percentage of eligibility was 90,55% and was included in the "very feasible" category. The trial process was attended by PTM students who were taking CAD 2 courses. From the user response data of 70 respondents, it was obtained that the average eligibility percentage was 91,24% and was included in the "very feasible" category. The conclusion is that the results of the reconstruction of the Computer Aided Design 1 course are very feasible and suitable for use in the learning process.

Abstract

In the current era, automatic motorbikes are the most popular motorbikes and are most widely used for everyday purposes. The motorcycle population always increases by around 5 million units every year. Of this amount, around 70% are motorbikes of the matic type, aka scooters. One trick that is usually used by automatic motorbike lovers to upgrade the characteristics of their automatic motorbike is to replace a part called the CVT roller. The aims of this study were: (1) To find out the effect on fuel consumption produced by a 110cc automatic motorcycle using variations in roller weight. (2) Knowing the effect on fuel consumption produced by 110cc automatic motorbikes using variations of engine speed. (3) Knowing the effect of using roller weight variations at RPM variations on fuel consumption on 110cc automatic motorcycles. The research method used is experimental. The research data was obtained by measuring the Honda BeAT New 2018 motorcycle sample. The independent variable is roller weight Variation and Variation of engine rotation. The dependent variable is fuel consumption. The data obtained were then analyzed using quantitative descriptive techniques by describing them in the form of graphs and tables. The results of this study are: (1) The use of variations roller weight 10, 12, and 14 grams have an effect on fuel consumption. The use of a roller that is heavier or lighter than standard (12 grams) has the effect of producing a more different fuel consumption. (2) Variations in engine speed (3500, 5000 and 6500 RPM) have an influence on fuel consumption. Each increase in engine speed, the fuel consumption will also increase. This happens because the higher the engine speed, the higher the amount of fuel burned in the combustion chamber. (3) Has the effect of fuel consumption on the use of roller weight variations and variations of engine speed. This effect lies in the average fuel consumption using less standard rollers when compared to using lighter or heavier rollers. Overall, if you take the best, then the right choice is a standard 12 grams roller, because it has the lowest average fuel consumption value.

Abstract

In the current era, the transportation is growing rapidly. It has an impact such as air and noise pollution. Carbon monoxide is one of the dangerous pollutants. While the noise comes from the sound of the vehicle engine, horn, and exhaust. Slamet Riyadi street Surakarta is a protocol road that has a high level of vehicle density. So it is necessary to conduct research with the aim of knowing the effect of motor vehicle density on carbon monoxide concentrations and noise levels. The results showed that the concentration of Carbon monoxide on Slamet Riyadi street Surakarta in the morning and evening exceeded the quality standard of 16038.26 µg/Nm3and 16141.58 µg/Nm3. During the day it is still below the quality standard, which is 9425.86 µg/Nm3. Meanwhile, the daytime noise level on Slamet Riyadi street Surakarta which is calculated by the Leq formula also exceeds the quality standard of 82.33 dBA.

Abstract

Indonesia has the potential for water energy that can be utilized as a pico-scale hydroelectric power plant or PLTPH. Water is a renewable energy (EBT) which has the potential to be developed in Indonesia due to the geographical conditions that have a lot of water in mountainous areas as well as irrigation for residential areas. Water turbines can convert water energy into electrical energy. One type of turbine that can be utilized is a crossflow water turbine. This study aims to determine the effect of the number of blades with the use of a nozzle on the power and efficiency of the turbine produced by the crossflow water turbine. The study used experimental methods, the data obtained were analyzed using quantitative descriptive analysis techniques. Variations in the number of blades used in the study were blades with a total of 18 blades, 20 blades, and 22 blades, as well as variations in the angle of attack of the nozzle used, namely 20⁰, 25⁰, 30⁰, 35⁰, and 40⁰. The results showed that there was an effect of using the number of blades and nozzle diameter. The power and efficiency of the turbine fluctuate based on the water discharge. The highest data was obtained at a water discharge of 25.33 l/m, namely using a number of 22 blades using a nozzle diameter of 7 mm to produce 9.47 watts of electric power with an efficiency of 58%.

Abstract

The availability of fossil fuels in Indonesia has recently been running low due to exaggerated use of the fuel. To fulfill the electrical energy needs of the community which more environmentally friendly used, wind turbines can be used. In this study, researchers use a micro-scale horizontal axis wind turbine from wood and composite materials on the blades, where it try to determine the effect of each performance. This study uses an experimental method which is carried out at the Wind Tunnel Laboratory of the Mechanical Engineering Education, Sebelas Maret University. The variables are blades with a variety of composite and wood material. Performance of electrical power is investigated in this research. Data shows that the wind speed 5m/s - 6m/s composite without load produces the highest rotate, which is 544.64 rpm. While, wood material take lower at 494.2 rpm. The wind turbine is driven at 5 m/s – 6 m/s by using 12V of load. It produces 367.68 rpm and 6.771 watts for composites, and 303.6 rpm and 5.047 watts for wood. So it can be concluded blade materials could effect to the turbine performance.
