Abstract

Tujuan dari penelitian untuk mengetahui kondisi fuel filter yang dapat berfungsi dengan baik setelah dimodifikasi pada mobil Chevrolet Captiva. Penelitian ini dilakukan dengan metode eksperimen dan dalam penelitian ini data dikumpulkan melalui instrumen data pengujian dalam tabel yang kemudian dianalisis menggunakan teknik deskriptif rata-rata. Hasil penelitian menunjukkan bahwa sebelum dilakukan modifikasi pemasangan fuel filter tekanan bahan bakar di fuel rail pressure pada jarak tempuh 3000 km sebesar 97.946 Kpa. Saat dilakukan akselerasi lampu check engine menyala, sedangkan setelah dilakukan modifikasi pemasangan fuel filter didapatkan bahwa tekanan bahan bakar di fuel rail pressure pada jarak tempuh 3000 km sebesar 149.296 Kpa dan saat dilakukan akselerasi lampu check engine tidak menyala. Dapat disimpulkan setelah dilakukan modifikasi pemasangan fuel filter pada mobil Chevrolet Captiva kondisi fuel filter mampu berfungsi dengan baik sebagaimana mestinya.   The purpose of the research is to determine the condition of the fuel filter which can function properly after being modified on the Chevrolet Captiva car. This research was conducted using an experimental method and in this research data was collected through test data instruments in tables which were then analyzed using average descriptive techniques. The results of the research show that before the modification of the installation of the fuel filter, the fuel pressure in the fuel rail pressure at a distance of 3000 km was 97,946 Kpa. When accelerating, the check engine light comes on, whereas after modifying the installation of the fuel filter, it is found that the fuel pressure in the fuel rail pressure at a distance of 3000 km is 149,296 Kpa and when accelerating, the check engine light does not come on. It can be concluded that after modifying the installation of the fuel filter on the Chevrolet Captiva the condition of the fuel filter is able to function properly as it should.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan tiga merek oli mesin (AHM MPX2, Motul Scooter LE 4T, dan Enduro Matic) terhadap top speed sepeda motor Honda Beat eSP. Meskipun ketiga oli memiliki nilai viskositas yang sama (SAE 10W-30), harga dan standar klasifikasi API/JASO berbeda. Metode penelitian yang digunakan adalah eksperimen dengan teknik analisis data deskriptif rata-rata dan perbandingan persentase. Hasil penelitian menunjukkan bahwa pada putaran mesin rendah hingga menengah, ketiga merek oli memberikan performa top speed yang relatif serupa. Namun, pada putaran mesin tinggi (7.000 rpm), oli Motul Scooter LE 4T menunjukkan keunggulan dalam mencapai top speed yang lebih tinggi dibandingkan AHM MPX2 dan Enduro Matic. Secara keseluruhan, dapat disimpulkan bahwa penggunaan beberapa merek oli memiliki pengaruh terhadap top speed sepeda motor Honda Beat eSP, dimana oli Motul Scooter LE 4T memberikan performa top speed terbaik pada putaran mesin tinggi. This study aims to analyze the effect of using three engine oil brands (AHM MPX2, Motul Scooter LE 4T, and Enduro Matic) on the top speed of a Honda Beat eSP motorcycle. Although the three oils have the same viscosity value (SAE 10W-30), their prices and API/JASO classification standards differ. The research method used is an experiment with descriptive average data analysis techniques and percentage comparisons. The results show that at low to medium engine speeds, the three oil brands provide relatively similar top speed performance. However, at high engine speeds (7,000 rpm), Motul Scooter LE 4T oil demonstrates superiority in achieving higher top speeds compared to AHM MPX2 and Enduro Matic. Overall, it can be concluded that the use of different oil brands influences the top speed of the Honda Beat eSP motorcycle, with Motul Scooter LE 4T oil providing the best top speed performance at high engine speeds.

Abstract

Philosophy is a comprehensive truth that is often contested with the truth of science which is relative in nature. This article discusses the influence of the philosophy of education on learning strategies on the Education Technology of Teaching. (PTK). The philosophy of education is the one used in the study of educational problems. Philosophy will determine where our students want to be carried. The philosophy is a tool of values that leads and guides towards the achievement of educational goals. Therefore, the philosophy followed by a particular nation or group of people or by individuals (in this case Teachers) will greatly influence the educational objectives to be achieved. The application of educational philosophy in PTK not only enhances the technical aspects but also builds individuals who have ethical integrity, interpersonal skills and readiness to face the dynamics of global industry. In this case there is the influence of the philosophy of education on learning strategies in the education of professional technology

Abstract

This study aims to measure the extent of the level of success and mastery of students against competencies in learning Automotive Electronics by using experimental methods. The subjects in this study were students of the Automotive Electronics Electricity course with a sample size of 30 students consisting of control class (class A) and experimental class (class B) as primary data. The data analysis technique is the analysis requirement test, namely the normality test using the SPSS program with the Kolmogorov-Smirnov test and the homogeneity test, then the Independent T-Test is then carried out to measure the extent of the level of success and mastery of students against competencies in learning Automotive Electronics. Based on the data that has been obtained, the evaluation of student learning outcomes with the UNP e-learning-based blended learning approach is able to measure the extent of the success rate and mastery of students of competencies in learning Automotive Electronics so that it can provide an overview for lecturers to plan learning strategies in other lessons

Abstract

The development of interactive learning media is an urgent need at SMK Imelda Medan, especially in the subject of Fundamentals of Network Engineering and Telecommunications. This research aims to develop a standalone interactive E-Module that is valid and effective to improve student learning outcomes. The method used is Research and Development (R&D) with the 4-D model (define, design, develop, disseminate), involving experimental and control classes. The research sample consisted of 108 students of class X Computer and Network Engineering Expertise Programme, selected through purposive sampling. Data analysis included validity, reliability, effectiveness, and statistical tests such as Kolmogorov-Smirnov, Levene, MANOVA, and effect size calculation. The validation results showed that the E-Module was valid and reliable with a loading factor value > 0.7, AVE > 0.5, and reliability value > 0.8. The average score of experimental class students was higher (86.04), especially in practice with a difference of 10.67 points. The paired sample t-test showed a significant difference (p < 0.001) with a very large effect size (Cohen's d > 1.8). MANOVA confirmed significant multivariate differences. This study proved the high effectiveness of the E-Module and made theoretical, practical, and pedagogical contributions to digital learning in vocational education.
