Abstract

The main functions of tire are to withstand the vehicle’s load, continue the steering function and control the vehicle’s direction, transmit the driving force and vehicle’s braking on the road surface and reduce shock vibrations from the road surface. Therefore, optimal tire selection is something that needs to be considered for driving perfection. Taguchi methods is one of experimental design methods that is often used because of considerations of effectiveness and efficiency. However, Taguchi methods only can be used to solve a single response optimization problem. When dealing with multi-response problems, the responses are analyzed separately. This study aims to optimize Taguchi design using VIKOR method in production of car tires. The experimental design and responses used in this study were derived from car tire production data which analyzed using VIKOR methods and selected based on the optimum value to obtain the optimal combination of factors levels. The results of Taguchi's analysis are the first and third responses indicating the 16th experiment and second response indicating the 14th experiment which is the optimal combination. It can be concluded that Taguchi methods is inconsistent to producing optimal combination of levels of factors when dealing with multi-response problems, so additional methods are needed as Taguchi optimization methods in solving multi-response problems, including using VIKOR methods which results in the 2nd experiment being optimal combination.

Abstract

ABSTRAKPemerintah Indonesia berharap kualitas baik dari gas buang kendaraan khususnya sepeda motor, diperlukan bahan bakar kualitas tinggi yaitu bahan bakar dengan nilai oktan tinggi. Napthalene adalah senyawa hidrokarbon dengan rumus kimia C10H16O. Struktur kimia yang mirip bensin, memiliki rantai lebih panjang membuat Napthalene diduga dapat meningkatkan nilai oktan bensin. Tujuan penelitian yaitu menganalisis pengaruh rasio pencampuran Napthalene pada premium terhadap konsumsi bahan bakar (km/l) dan peningkatan kinerja pada mesin sepeda motor bebek jenis manual 110 cc dan 115 cc. Metodenya adalah eksperimen. Parameternya yaitu tingkat efisiensi konsumsi premium (km/l), peningkatan kinerja meliputi torsi dan daya (Horse Power) pada motor jenis tersebut.Rasio perbandingan Napthalene dan premium yaitu 3 gram/l, 6 gram/l dan 9 gram/l. Hasil uji menunjukkan rasio pencampuran Napthalene pada premium sebanyak 9 gram/l merupakan yang paling berpengaruh terhadap tingkat efisiensi konsumsi premium dan kinerja mesin pada kedua jenis motor tersebut. Aplikasi tersebut tentunya akan memperbaiki kualitas gas buang.Kata kunci : efisiensi, premium, naphthalene, nilai oktan ABSTRACTThe Indonesian government hopes that the good quality of vehicle exhaust gases, especially motorcycles, requires high quality fuel, namely fuel with a high octane rating. Napthalene is a hydrocarbon compound with the chemical formula C10H16O. The chemical structure is similar to gasoline, having a longer chain makes Napthalene allegedly able to increase the octane value of gasoline. The purpose of the study was to analyze the effect of the Napthalene mixing ratio at premium on fuel consumption (km/l) and performance improvement on the 110 cc and 115 cc manual motorcycle engines. The method is experimental. The parameters are the level of premium consumption efficiency (km/l), increased performance including torque and power (Horse Power) on this type of motorcycles. The ratio of Napthalene and premium is 3 grams/l, 6 grams/l and 9 grams/l. The test results show that the Napthalene mixing ratio at premium as much as 9 grams/l is the most influential on the level of premium consumption efficiency and engine performance on both types of motorcycles. The application will certainly improve the quality of exhaust gas.Keywords: efficiency, premium, naphthalene, octane rating
