Abstract

Engine performance is a critical parameter in automotive engineering as it directly affects power output, torque characteristics, and overall vehicle efficiency. One of the components that significantly influences engine performance is the exhaust system, which regulates exhaust gas flow and back pressure. This study aims to experimentally analyze the effect of replacing a standard exhaust system with an aftermarket exhaust system on the performance of a 2NR-VE engine. The research employed an experimental method using a comparative design with two testing conditions: a factory-standard exhaust system and an aftermarket exhaust system. Engine performance testing was conducted using a dynamometer (dyno test) to measure horsepower and torque across various engine speed ranges (RPM). Each testing condition was performed repeatedly, and the resulting data were averaged to reduce measurement errors and minimize the influence of operational fluctuations. The experimental results indicate that the aftermarket exhaust system significantly improves engine performance. The maximum power increased from 82.5 HP to 91.6 HP, while the maximum torque rose from 131.2 Nm to 154.4 Nm. These improvements suggest that the aftermarket exhaust configuration effectively reduces exhaust back pressure and enhances exhaust gas flow efficiency. Therefore, replacing the exhaust system can be considered an effective approach to improving engine performance, provided that the modification is technically appropriate and complies with applicable emission and noise regulations.

Abstract

Penelitian ini mengkaji, mendeskripsikan dan menganalisis implementasi Metode Talqin dalam kegiatan ekstrakurikuler Baca Tulis Al-Qur'an (BTQ) di SDN 01 Pagi Kota Bambu, Jakarta Barat, dengan fokus pada proses pelaksanaan, faktor keberhasilan, kendala, dan dampaknya terhadap peserta didik. Penelitian kualitatif dengan pendekatan studi kasus ini menggunakan teknik pengumpulan data melalui wawancara mendalam, observasi partisipatif, dan studi dokumentasi. Informan dipilih secara purposive sampling, meliputi kepala sekolah, koordinator program, guru pelaksana, siswa peserta, serta orang tua. Hasil penelitian menunjukkan bahwa implementasi metode ini dilaksanakan melalui siklus pembelajaran terstruktur (Talqin Guru, Jama'i, Fardi, dan Tikrar) yang dipadukan dengan prinsip pembelajaran berdiferensiasi dan scaffolding, sehingga metode transmisi tradisional ini menjadi responsif terhadap kebutuhan individu siswa. Keberhasilan program ditopang oleh terbangunnya kemitraan ekosistem pendidikan yang solid antara kepemimpinan sekolah yang visioner, kreativitas guru, dukungan aktif orang tua, dan keterlibatan siswa. Dampak yang dihasilkan bersifat holistik, mencakup peningkatan kompetensi kognitif (akurasi membaca dan hafalan), perkembangan afektif (kepercayaan diri, growth mindset, dan internalisasi nilai karakter Qur'ani), serta penguatan psikomotorik.
