Abstract

Penelitian ini mengkaji tentang perubahan kadar nilai pada CO dan HC yang didapat dari emisi gas buang, sepeda motor FI memakai ECU Programmable (3 variansi perlakuan pada saat penginjeksian dan saat pengapian) penggunaan 3 jenis busi dan 3 jenis campuran ethanol di setiap pengujian. Penelitian bertujuan untuk mengetahui hasil optimal pada pengujian terhadap emisi gas buang yang dihasilkan sepeda motor. Penelitian ini berjenis eksperimen dengan metode taguchi. Objek penelitian ini adalah sepeda motor FI. Dengan hasil penelitian, karbon monoksida (CO) dengan respon rata-rata optimal yaitu faktor A2 (2,59%), B3 (2,81%), C1 (2,67%), dan D3 (1,63%), sedangkan respon rata-rata optimal hidrokarbon (HC) yaitu faktor A2 (257,33ppm), B3 (252,44ppm), C3 (295,22ppm), dan D3 (230,89ppm). This study examines the changes in CO and HC values obtained from exhaust emissions, FI motorcycles using Programmable ECU (3 variants of treatment at the time of injection and at the time of ignition) using 3 types of spark plugs and 3 types of ethanol mixture in each test. The research aims to determine the optimal results in testing the exhaust emissions produced by motorcycles. This research is an experimental type with the Taguchi method. The object of this research is FI motorcycle. With the results of the study, carbon monoxide (CO) with the optimal average response is factor A2 (2.59%), B3 (2.81%), C1 (2.67%), and D3 (1.63%), while the optimal average response of hydrocarbons (HC) is factor A2 (257.33ppm), B3 (252.44ppm), C3 (295.22ppm), and D3 (230.89ppm).

Abstract

Tafsir is the science of understanding the verses of the Al-Quran which functions as mubayyin (explanation) of the meaning and significance of the contents of the verses of the Al-Quran so that the meaning can be understood and comprehended by all groups and becomes a guide or guidance in life for Muslims. The development of Al-Quran interpretation began during the time of Rassulullah SAW and continued to develop from the time of the companions, tabi'in to the modern era. This research discusses the biographies of tabi'in and also includes several examples of interpretations of Al-Quran verses based on these interpretations. This research aims to get to know the mufasssir during the tabi'in period and find out traces of their biographies and find out examples of interpretations of Al-Quran verses based on interpretive styles. This research method uses qualitative methods and literature studies and examines tafsir books, hadith books, Islamic book references, language book references and portal media such as journals. The results of this research serve as a guide for Muslims to learn more about tabi'in biographies and upgrade the interpretation of verses by including examples of interpretations of verses based on their style.
