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

Penerangan Jalan Umum (PJU) memiliki peran penting dalam mendukung keselamatan dan kenyamanan pengguna jalan, terutama di malam hari. Terdapat dua sistem utama yang banyak diterapkan, yaitu PJU tenaga surya (PJUTS) dan PJU konvensional yang menggunakan listrik PLN. Kajian teoritis ini dilakukan untuk membandingkan keduanya dari sisi biaya investasi awal, biaya operasional tahunan, serta biaya pemeliharaan dan penggantian komponen dalam periode 20 tahun. Hasil analisis menunjukkan bahwa PJUTS memerlukan biaya investasi awal yang relatif lebih tinggi, namun memiliki biaya operasional yang rendah karena tidak dibebani tagihan listrik bulanan. Sebaliknya, PJU konvensional memiliki investasi awal lebih rendah, tetapi disertai tagihan listrik rutin dan biaya perawatan berkala yang menyebabkan total biaya menjadi lebih besar dalam jangka panjang. PJUTS dinilai lebih sesuai diterapkan di wilayah terpencil atau daerah yang belum terjangkau jaringan PLN, sedangkan PJU konvensional tetap relevan untuk daerah perkotaan yang telah memiliki infrastruktur listrik memadai. Kajian ini diharapkan dapat menjadi bahan pertimbangan bagi pemerintah daerah dan pemangku kebijakan dalam menentukan pilihan sistem PJU yang lebih ekonomis, efisien, dan berkelanjutan sesuai kondisi wilayah dan kebutuhan setempat.

Abstract

Embankment dams are critical infrastructure requiring comprehensive geological and geotechnical investigation to ensure long-term structural integrity and prevent catastrophic failure. This study presents the results of two-stage Multichannel Analysis of Surface Waves (MASW) investigations conducted at Cabean Dam core zone to characterize shear wave velocity (Vs) profiles and identify weak zones susceptible to seepage and slope instability. The first stage (2022) involved 17 survey lines while the second stage (2025) comprised 11 additional lines targeting critical areas. Shear wave velocity values ranged from 78–756 m/s, indicating significant material heterogeneity. Low Vs anomalies (78–200 m/s) were identified in the upper 0–7 meter depth at survey lines L-01, L-07, L-08, and L-09, correlating with residual soil having high permeability values up to 3.06×10⁻⁴ m/s and Lugeon values reaching 25.34 Lu. Integration of MASW data with borehole logs confirmed material classifications ranging from Site Class E (soft soil) at shallow depths to Site Class B (stiff soil) at greater depths. The identified weak zones pose significant risks for seepage, internal erosion (piping), and slope instability, requiring remedial measures including recompaction, optimized internal drainage design, and enhanced instrumentation monitoring. This research contributes methodological advancement in applying MASW as an integral component of staged investigation protocols for embankment dam projects, particularly for monitoring and refining geological-geotechnical conditions during construction phase. Results serve as a reference for practitioners and researchers in geotechnical dam engineering for improving safety and reliability of embankment dam infrastructure in Indonesia.

Abstract

As the majority of Indonesian citizens, Muslims cannot avoid that a lot of corruption is carried out by people who are Muslim. In Indonesia's positive law, there are still some crimes that carry the death penalty. In Islam, it implies the imposition of punishment that will be able to provide a deterrent effect for perpetrators of corruption, namely the death penalty. One of the arguments that imply the death penalty for perpetrators of corruption is contained in the Qur'an Surah Al-Maidah verse 33. This paper aims to provide thoughts related to the death penalty status for Corruptors in the perspective of Islamic law, so that at least it becomes material reflection and reminding that corruption is a bad act and is strictly prohibited by Islam, because the bad impact it has on a society and nation is very large.
