No full textEntrepreneurship is one aspect that affects economic growth in Iindonesia. Students are the next generation who are expected to be able to create entrepreneurs in the future. The purpose of this research is to analyze entrepreneurial interest based on vocational education level in mechanical engineering and the factors driving this interest. This research uses a mix-method that combines a quantitative approach and a qualitative approach. The subjects of the research were Class XII students of State 2 Vocational High School in Surakarta, department of mechanical engineering, totaling 120 people and D3 Mechanical Engineering students at Sebelas Maret University, totaling 57 people. Data collection techniques to determine the entrepreneurial interest of students (quantitative data) using the questionnaire method while knowing the factors that influence entrepreneurial interest (qualitative data) using the interview method. Analysis of data for quantitative data using descriptive analysis and for qualitative data using thematic analysis. The result showed that the majority of students wanted to be entrepreneurs but a different levels of time. Factors that influence entrepreneurial interest are divided into two, namely internal factors and external factors. The internal factors driving entrepreneurial interest are motivation that comes from the individual’s self and enthusiasm to face risk challenges. External factors driving or family, entrepreneurial interest are motivation the arises due to the influence of friends or family, entrepreneurial experience and entrepreneurship education

Analisis Natural Weathering pada Komposit Recycled Polypropylene dan Serat Bambu
Get PDFAbstract. The main objective of this study was to analyze the effect of Natural Weathering on the tensile strength and microstructure of recycled polypropylene (rPP) composites with bamboo fiber reinforcement. The rPP-bamboo composite specimens were made using extrusion molding and injection molding machines. The weight fraction used in making the specimens was 10% bamboo fiber and 90% rPP. The rPP-bamboo samples were tested with 3 variations of exposure time, 0 months (without exposure), 1 month and 2 months according to ASTM D1435-05 standard. From the 3 variations of exposure, a tensile test was carried out with the ASTM D638 type V standard to evaluate the value of tensile strength, modulus of elasticity and elongation. Then SEM (Scanning Microscopy Electrone) was performed to see the microstructure of the composite. The results showed that the tensile strength at exposure time of 0 months, 1 month and 2 months was 18.1 MPa with an elongation of 5%, 19.5 MPa with an elongation of 6.4% and 19.3 MPa with an elongation of 6.6%. Young's modulus values showed a decrease with increasing exposure time, ranging from 222 MPa in the sample without exposure to 141 MPa at an exposure time of 2 months. With SEM it is known that, the microstructure of the composite at the beginning of exposure shows a strong bond between the fiber-matrix even though there are some voids in the specimen. At 2 months of exposure, it was seen that there was a gap between the matrix and bamboo due to the hydrophilic nature of bamboo fiber

The dependent variable in this study is fuel consumption under standard conditions and those who have used step-up voltage. The control variable used was a 2013 Honda Beat motorcycle and a 50 ml measuring cup. The results of this study: (1) The use of step up voltage affects the fuel consumption of Honda Beat motorcycles in 2013 because there is a difference in fuel consumption before using step up voltage and after using step up voltage. The use of this tool has been proven to be able to reduce fuel consumption by 0.87 ml/minute at 1500 rpm, with these results, the use of step up voltage affects the combustion quality of the fuel and air mixture in the combustion chamber of a motor vehicle which becomes more perfect due to a decrease the fuel consumption of the tested motor vehicle. (2) The use of Pertamax fuel can reduce fuel consumption. The average fuel consumption produced is 6.59 ml/minute, a decrease of 2.33 ml/minute from pertalite fuel. (3) The best configuration to obtain the lowest fuel consumption is to use a step up voltage with Pertamax fuel at a voltage of 14.3 V. This configuration is the best than the other configurations, with a fuel consumption of 3.76 ml/minute at 1500 rpm
Studi Perbandingan Bahan Bakar Minyak Dengan Bahan Bakar Gas LPG (Liquified Petroleum Gas) Terhadap Konsumsi Bahan Bakar Sepeda Motor 4 Tak 125 CC
Get PDFLiquified Petroleum Gas is a gaseous hydrocarbon produced from gas and oil with the main components being propane and butane. The use of LPG gas fuel was chosen because it is able to reduce the amount of fuel consumption by up to 30% more efficient than fuel oil in general. The use of LPG fuel can be optimized by modifying the size of the pilot jet, the size of the main jet and the gas flow valve opening on the regulator. The purpose of this study was to investigate how big the ratio of fuel consumption between LPG fuel and pertalite fuel is. This study used Honda Supra 125 D as a sample. The variables used in this study include: variations in the size of the pilot jet (40, 42, 45), variations in the size of the main jet (72, 98, 120) and the gas flow valve opening on the regulator (10%, 15%, 20%). The results showed that the lowest LPG fuel consumption value was obtained at 156.5 grams per 10 kilometers, while the pertalite fuel consumption value was obtained at 232.9 grams (after converting from liters to grams). The most influential factor is the replacement of the main jet size on the use of LPG fuel
