Abstract

Implementation of the developed Learning Implementation Plan (LIP) will result in the risk of learning not being in line with expectations if the validity of the product is not guaranteed. Thus, this research aims to investigate the validity of developing project-based lesson plans to improve effective learning outcomes. This research is research and development with a quantitative approach using the ADDIE model procedure. To obtain product validity results, the stages used are only in the development phase. The subjects in this research were 2 expert lecturers and 3 productive teachers with expertise in light vehicle engineering, and the instrument used was a feasibility questionnaire. The findings were that the project-based LIP that was developed had an average score of 88.7% in the valid category. This study concludes that it has succeeded in developing a product in the form of a valid and usable project-based lesson plan. Carrying out learning using lesson plans that are integrated with project-based learning can be an alternative to providing more meaningful learning and have a positive impact on student development.

Abstract

This study aims to identify self-concept and interest in entrepreneurship, and inhibiting factors in entrepreneurship for students of the Automotive Engineering Department, Faculty of Engineering, Padang State University. The research subjects are students of the entry year 2019, 2020, 2021, and 2022, with a total of 100 students. The data collection method used a questionnaire about self-concept, interest in entrepreneurship and inhibiting factors in entrepreneurship. The data analysis method used is descriptive analysis. The results of the analysis show that the entrepreneurial self-concept of students is 88.64%, so it can be interpreted is very high. The results of the analysis of interest in entrepreneurship are 81.06%, this shows a very high interest in students to become entrepreneurs. Finally, the results of the analysis of the inhibiting factors for students in entrepreneurship are 68.24%, this shows that the inhibiting factors for entrepreneurship are high. Efforts that must be made by the government are in the form of policies that support entrepreneurial activities. The role of the business world and industry is in the form of capital support and sharing experiences with students, while universities must create entrepreneurship programs that can be used as a forum for entrepreneurship training by students.

Abstract

Hole injector memiliki peran terhadap campuran bahan bakar di ruang bakar. Penelitian ini bertujuan untuk mengetahui penggunaan hole injector variasi terhadap konsumsi bahan bakar, top speed, dan emisi gas buang pada sepeda motor type matic. Metode eksperimen dilakukan dengan membandingkan penggunaan hole injector standar (6 lubang) dan hole injector variasi (8 lubang). Data penelitian secara langsung diambil dari kinerja sepeda motor Honda Beat Street kemudian disajikan dengan metode deskriptif persentase. Hasil penelitian berupa konsumsi bahan bakar, top speed, dan emisi gas buang berhasil diperoleh dan dianalisa lebih lanjut. Dari analisa dapat disimpulkan bahwa injector variasi 8 lubang memiliki hasil yang tidak baik karena konsumsi bahan bakar menjadi boros dan peningkatan emisi gas buang. Sehingga penggunaan injector ini tidak direkomendasikan untuk digunakan pada sepeda motor matic. Hole injectors have a role in the fuel mixture in the combustion chamber. This study aims to determine the usage of hole injector variations on fuel consumption, top speed, and exhaust emissions on matic type motorbikes. The experimental method was carried out by comparing the use of standard hole injectors (6 holes) and hole injector variations (8 holes). Research data was directly taken from the performance of Honda Beat Street motorbike and then presented with descriptive percentage method. The research results in the form of fuel consumption, top speed, and exhaust emissions were successfully obtained and further analyzed. From the analyses it can be concluded that the 8-hole variation injector has poor results due to wasteful fuel consumption and increased exhaust emissions. So the use of this injector is not recommended for use on matic motorbikes.

Abstract

Meningkatnya pertumbuhan jumlah kendaraan bermotor dapat menimbulkan dampak negatif, diantaranya konsumsi bahan bakar fosil yang meningkat dan polusi lingkungan yang disebabkan oleh emisi gas buang pada sepeda motor. Salah satu jenis bahan bakar yang banyak dikonsumsi adalah pertalite sebanyak 79% dibandingkan jenis bahan bakar bensin lainnya. Upaya yang diperlukan dalam mengatasi dampak tersebut yaitu dilakukan pencampuran bahan bakar pertalite dengan bioetanol dari tebu. Penelitian ini bertujuan untuk menurunkan konsumsi bahan bakar dan mengurangi emisi gas buang pada sepeda motor. Variasi bahan bakar yang digunakan adalah BE0, BE5, BE10, BE15, BE20, dan BE25. Hasil penelitian menunjukkan, penurunan terbesar konsumsi bahan bakar terjadi pada variasi bahan bakar BE25 sebesar 19% dan penurunan emisi gas buang karbon monoksida (CO) dan hidrokarbon (HC) terjadi pada variasi bahan bakar BE25 sebesar 28% dan 61% dibandingkan dengan variasi bahan bakar standar BE0. Increasing growth in the number of motorized vehicles can have negative impacts, including increased consumption of fossil fuels and environmental pollution caused by exhaust emissions from motorcycles. One type of fuel that is widely consumed is pertalite as much as 79% compared to other types of gasoline. The effort needed to overcome this impact is to mix pertalite fuel with bioethanol from sugar cane. This research aims to reduce fuel consumption and reduce exhaust emissions on motorbikes. The fuel variations used are BE0, BE5, BE10, BE15, BE20, and BE25. The research results showed that the largest reduction in fuel consumption occurred in the BE25 fuel variation by 19% and the reduction in carbon monoxide (CO) and hydrocarbon (HC) exhaust emissions occurred in the BE25 fuel variation by 28% and 61% compared to the fuel variation standard BE0.

Abstract

The need and utilization of energy in society exceed available production. This condition requires acceleration and efforts to find solutions through the diversification of palm shell biomass into solid fuel briquettes. Palm shells have the potential as biomass and renewable energy sources that are selected based on strategic, technical, and environmental considerations. Its utilization so far has only been burned directly which causes air pollution or used as road paving in oil palm plantations. The environmental impact is the accumulation of solid waste, and global warming in the Crude Palm Oil processing industry. The research objective was to obtain the calorific value of palm kernel shell briquettes with carbonization process. The experimental research method carried out by innovating palm kernel shell briquette raw materials at various percentage variances (90%: 10%, 85%: 15%, 80%: 20%, 75%: 25%) using tapioca adhesive. The technical parameters of briquettes making are molding pressure of 10 MPa, particle grains of 60 mesh, carbonization temperature of 400oC; 450oC; 500oC with a holding time of 1 hour. From this study, the calorific value of palm kernel shell charcoal (PKSC) briquettes at a concentration of 85%;15% at a temperature of 400oC was 25.86 MJ/kg with tapioca adhesives as the highest calorific value parameters. The technology used to make palm kernel shell charcoal briquettes is a potential development that can be recommended as a precursor to solid fuels. The impact of developing PKSC biomass energy briquettes is an innovation in utilizing waste to create solid fuels. The implications of this research can be applied by home industries or households. This research is a contribution to solutions in overcoming energy needs and deficiencies as a form of sustainable energy..
