Abstract

Abstrak Aftercooler merupakan salah satu component pada air system yang berfungsi untuk menurunkan temperature udara bertekanan pada component turbocharger yang akan masuk ke combution chamber, aftercooler dengan jenis jacket water aftercooler (JWAC) jauh lebih efisien dalam perpindahan panas dan kinerja menurunkan temperature secara keseluruhan dibandingkan dengan air to air aftercooler (ATAAC). Keunggulan ini disebabkan oleh karakteristik perpindahan panas air sebagai medium pendingin yang lebih baik. Sistem air to water menghasilkan suhu udara masuk yang lebih rendah, kepadatan udara yang lebih tinggi yang berarti lebih banyak molekul oksigen masuk ke dalam combution chamber yang mengoptimalkan percampuran udara dan fuel yang seimbang dan pada akhirnya, efektivitas aftercooler yang lebih besar. Perbedaan efek pendinginan ini menyebabkan jacket water aftercooler mempertahankan kepadatan udara yang lebih tinggi. Dengan menurunkan temperature udara bertekanan secara efektif, aftercooler dengan sistem air to water membantu mencegah terjadinya knocking, memungkinkan pembakaran bahan bakar yang lebih sempurna, dan berpotensi meningkatkan kinerja unit alat berat. Kata kunci: Aftercooler, ATAAC, efektif , JWAC, temperature

Abstract

Fuel consumption in motorized vehicles is one of the main indicators of the efficiency of land transportation systems. Besides being determined by vehicle technical specifications and driver behavior, fuel efficiency is also significantly influenced by infrastructure conditions, particularly road geometry. Road geometry encompasses elements such as gradient, horizontal and vertical curvature, lane width, and road surface quality, all of which affect vehicle dynamics while driving. Roads with suboptimal geometric designs can cause increased engine workload, inefficient acceleration, and repeated deceleration, ultimately resulting in fuel waste. This study aims to examine the extent to which road geometric elements affect motorized vehicle fuel consumption. Through a literature-based qualitative and quantitative analysis approach and technical evaluation, it was found that efficient geometric design can significantly reduce fuel consumption. These findings emphasize the importance of integrating energy efficiency aspects into road planning and design processes to create a land transportation system that is not only effective and economical, but also sustainable and environmentally friendly. Keywords: Road design, energy efficiency, road geometry, fuel consumption, land transportation

Abstract

This study aims to provide a profile overview of the students' creative thinking skills on Newton's Laws. The research used was a descriptive quantitative method. The research was conducted on grade VIII students at one of the State Junior High Schools in Singkawang City. The subjects in this study were selected by purposive sampling totaling 36 students. The research data was collected using a creative thinking skills test totaling 8 essay questions. Data were analysed using descriptive percentages. The results of the study showed that (1) students who were at a medium level of creative thinking were 81%, students who were at a low level of creative thinking skills were 19%; (2) the percentage results of creative thinking skills per indicator, namely fluency 69.17%, flexibility 57.92%, originality 37.50%, and elaboration 50.83%. Thus, it can be concluded that students' creative thinking skills were still low.

Abstract

Penelitian ini bertujuan untuk menganalisis penyebab kebocoran oli pada sisi belakang engine pada unit excavator Komatsu PC 2000-8. Kebocoran oli pada sistem pelumas dapat menyebabkan penurunan kinerja engine dan kerusakan pada komponen lainnya. Metode yang digunakan dalam penelitian ini adalah penelitian lapangan dengan melakukan identifikasi penyebab, pengamatan dan diagnosis, pengumpulan data, analisis, penyebab yang dicurigai, kesimpulan, dan tindakan perbaikan. Hasil penelitian menunjukkan bahwa penyebab utama kebocoran sistem pelumasan pada sisi belakang engine dikarenakan terjadi contact surface pada sleeve rear seal yang mengalami keausan, sehingga dapat yang mengakibatkan kebocoran oli engine ke dalam sistem PTO. Dengan perbaikan pada komponen yang sesuai standar, kebocoran sistem lubrikasi ini dapat diatasi dan diminimalisasi.

Abstract

Penelitian ini berjudul “Analisis External Leak pada komponen Differential HD785-7 di PT BUMA (BRC)”, yang bertujuan untuk mengetahui penyebab terjadinya external leak pada komponen differential Komatsu HD785-7 dan mengetahui tindakan yang tepat untuk mencegah terjadinya external leak. Metode analisis yang digunakan meliputi analisis visual, analisis trend, dimension inspection, dan perbandingan dengan standard pabrik. Berdasarkan hasil analisis trend, terjadi 14 kali kejadian kebocoran eksternal pada differential diseluruh job site PT BUMA. Hasil analisis visual, ditemukan kebocoran pada seal oil. Hasil dimension inspection pada komponen coupling differential, ditemukan bahwa coupling mengalami keausan di bagian sisi distance coupling dan tidak terdapat pengukuran dimensi coupling terhadap ukuran standard dari pabrik di QA sheet BRC. Dari penelitian ini menunjukkan bahwa penyebab terjadinya external leak, karena keausan dari bagian coupling differential yang diakibatkan pemakaian berulang /part reuse yang dilakukan secara berkelanjutan.

Abstract

This study aims to improve students’ learning interest in Islamic Cultural History (Sejarah Kebudayaan Islam) through the implementation of animated video learning media assisted by the Canva application. The research employed Classroom Action Research (CAR) conducted in two cycles, consisting of planning, action, observation, and reflection stages. The subjects of this study were 22 eighth-grade students of MTs Laboratorium Kota Jambi in the academic year 2025/2026. Data were collected through observation sheets, questionnaires on learning interest, interviews, and documentation. The indicators of learning interest measured in this study included students’ enjoyment, attention, active participation, and motivation during the learning process. The results showed a significant improvement in students’ learning interest after the implementation of animated video media assisted by Canva. In Cycle I, students’ learning interest increased moderately, while in Cycle II it reached the expected success criteria with a percentage above 80%. These findings indicate that the use of Canva-assisted animated video learning media can create an engaging and interactive learning atmosphere, thereby effectively increasing students’ learning interest in Islamic Cultural History. Therefore, this media can be recommended as an alternative innovative learning strategy to enhance students’ engagement in the classroom.
