Abstract

Study program of mechanical engineering education (PSPTM) as an education organization needs to improve its learning quality. In this study, students will also be included to give input so that PSPTM management will be able to determine a strategy change in order to be better and the results to be accepted by the management and the students. The assessment from students is treated as a response to the difference between the rate of expectation and the real level of performance that has been previously perceived. This study is also used the seven dimensions of quality of learning such as the course objectives, lectures, the course structure, learning activities, lectures, companion (assistant) and evaluation. The results of the study by measuring student’s expectations and perceptions using Importance Performance Analysis obtain quality indicator P13 with suitability value 62.2% are quite well, P16 indicator with a value of 71.2% suitability value is also quite good, P18 indicator with a value of 78.4% with satisfactory grades, had a good assessment in practice and needs to be maintained.

Abstract

Problem of rural communities in Indonesia is difficult to obtain kerosene on the market. Team researchers have tried to provide a solution by building a biogas digester type "dome" in the Tuwung village as a model, but this effort has a new problem that the resulting biogas digester quickly run out. From the results of the investigation are diagnosed digester output pipe clogged by water causing increased pressure and temperature so that the process of formation of biogas disturbed and also not optimum biogas stove hole so wasteful. To obtain the solution of this problem, this study aims: 1) Designing and making a safety valve digester; 2) Designing the optimum pit stove; 3) Creating pressure gauge digester. The method used in this research is true experimental research. the results of this study were: 1) A safety valve made from plastic bottles with a capacity of 2 liters, and filled with water to a depth of 6 cm, so it can withstand the pressure of the digester to 100.58 atm.2) Diameter hole obtained optimum stove is 6.5 mm; 3) Pressure gauge manometer water digester is made of transparent plastic hose diameter of 6 mm.

Abstract

Problems oil reserves are dwindling caused the crisis, the effects of the crisis has been felt in the last few years. It encourages researchers to participate in developing renewable fuels. This study, try blend Biosolar Pertamina with jatropha biodiesel. The purpose of this study was to determine the effect of the composition of jatropha into Pertamina Biosolar to volumetric efficiency of direct injection diesel engine 4- stroke, 4-cylinder with a cylinder volume is 2.8 liters. The composition of the fuel for the experiment is D100 ( Biosolar Pertamina 100% ) ; D90J10 ( Biosolar 90% Jatropha 10%) ; D80J20 ( Biosolar Pertamina 80% Jatropha 20%) dan D70J30 ( Biosolar 70% Jatropha 30% ). The method used is experiment. Results of the study are (1) Effect increase the percentage of biodiesel jatropha to engine diesel power is the power at all loads to be decreased. Values drop in brake power at each of the largest load variation occurs in the mixture D70J30 with a value decline of 0.75%, 5.28%, 10.37% and 9.85% of the power with fuel D100. (2) Effects of jatropha biodiesel percentage increase also resulted in torque at all loads going down. the lowest decline in every variation is incurred on fuel D70J30 brake power is calculated from the value D100, with a value decline of 0.74%, 5.02%, 9.40%, and 8.96%. (3) Effect throughout the fuel mixture of the volumetric efficiency of diesel engines is causing decreased volumetric efficiency, the biggest decline was 6.33%, 6.61%, 6.33%, and 6.19% in the fuel D80J20 volumetric efficiency is calculated from the value D100. Suggested solutions to overcome the problems of a decrease in volumetric efficiency is by placing the intake valve settings, so that when air intake into the cylinders could be longer and with the modification that with the addition of a supercharger or turbocharger, more preferably also added intercooler.

Abstract

The buggy car is a vehicle possessing mini dimension boarded by single to four passenger seats in which it is able to provide the demand of transportation in industrial estates and plantations such as oil palm plantations. The massive need for a simple transportation to assist the specific human works in the area of plantations in Kalimantan is an appropriate reason to choose this technology. Based these, researchers focus to analyze a simple transportation model, inexpensive, however highly efficient land device for plantation works. This vehicle enormously expected to help the modes of transportation in general plantations and estates. Beside those, it can be an educational model in vocational education of university and college to enhance the student’s interest and skill to deepen the field of educational mechanical engineering. Furthermore the author and team attempt to design then analyze the mechanical drive system and power transmission of Buggy automobile with a simple construction and components that are easily found in the market. This research has conducted by implementing the experimental research type (True Experiment Research). By the results of analyzing the types of actuators, the type of power transmission and steering model for Buggy automobile, it has been obtained that the transmission system used is the CVT (Continually Variable Transmission) type that mechanical works based on engine speed and centrifugal force. Eventually the total weight of buggy car is 157 kg, minimum power at about 5,37 HP, Shaft diameter at around 55 mm, Pitch diameter of Gear spur (dp) integrated in differential gear is 48 mm. The total weight of the vehicle including the weight of the driver has a significant impact on engine performance. Overall, light vehicles must look better because the engine capacity is adjusted to the chassis

Abstract

The purpose of this study was to determine whether there is an influence between the learning outcomes of students who were taught by lecturing on the subjects of gasoline fuel system in class XI SMK 1 Palangkaraya. This study used two different classes that involved 32 students of class XI TKR (Light Vehicle Engineering) SMK 1 Palangkaraya are divided into two classes, namely, class XI TKR 1 with 16 people and the number of students in class XI TKR 2, amounting to 16 people, and the type of research is experimental. In this study the instrument in the form of a multiple choice test to collect data of student learning outcomes. Data were analyzed with normality test, homogeneity test and t-test, normality test for pre-test experimental class X2calculated<X2table, is 3.859 <9.488, test of normality to pre-test the control class X2calculated<X2table, namely 3.178 <9.488, while for normality teston post test of experimental class X2calculated<X2table, namely 3.846 <9.488, normality test of post test of control class X2calculated<X2table, namely 3.011 <9.488, test of homogeneity obtained Fcalculated = 1.01 < Ftable = 2.31 otherwise homogeneous. T-test obtained tcalculated = 10.51> ttable = 2.042, so there is an influence on student learning outcomes taught using learning model-type Group Investigation (GI) on the material maintenance of gasoline fuel system components in class XI TKR (Light Vehicle Engineering) SMK Negeri 1 Palangka Raya academic year 2014/2015.

Abstract

The low students study results in the learning activity using mechanic measurement devices is a background of the problem, caused by teacher’s teaching method is still using a conventional approach which is just a verbal lecture without using computer media, it can be seen from student’s low study results. This research aims to find out the level of students’ comprehention on the subject material with the number student of 30. The research is designed in three stages which are pretest stage, learning stage, and post test stage. Data collecting method to be used are documentation, dan test method. Instruments to be used are test and questionnaire. This research is a descriptive research that had been done on the tenth grade student of TKR SMK Karsa Mulya Palangka Raya tahun ajaran 2014/2015. The student achievement level reached 83,4%. It means that learning process using tutorial video on the subject material Using mechanic measurement devices is achieved as per the achievement level criteria of learning process which is 80-100%. It can be concluded that learning model CAI (Computer Assistance Instruction) in the form of tutorial video can be used as an alternative in delivering subject material Using the mechanic measurement devices.
