Abstract

The development of motor vehicle technology has urgency of increasing the efficiency for the engine of fuel requirements that will be used in the combustion process to produce output parameters. One of the elements for an effective combustion process for the fuel mixture composition is the quantity and the air capacity to be supplied for each cylinder. The construction of intake manifold is one of minor losses for requirement capacity of air when intake suction take occured. The addition of Axial Fan in the intake manifold system of diesel motors is expected to meet the air supply capacity and minimize minor losses, so the performance engine like : volumetric efficiency, torque and power increased. Fundamental of air Intake System Performance Method to inducting (forces) amount of the air through Fan Axial Double Blade blades. This study uses a quasi-experimental method that compares the intake manifold with or without the installation of axial (standard) fan to the torque and power generated from four diesel motors (4) steps. From the test obtained an average torque increase of 22%, with the highest torque at the beginning of 1150 rpm engine speed of 41.8 Nm, while the average power increase of 13% with a power rating of 8 KW at 2200 rpm engine speed. While the volumetric efficiency experienced an average increase of 6% with a significant percentage of engine speed of 2200 rpm which reached 98.8%.

Abstract

Penelitian ini bertujuan untuk mencari efektivitas campuran bahan bakar dengan minyak atsiri dan aceton guna menunjang unjuk kerja mesin dua langkah. Minyak atsiri dapat berfungsi sebagai pelumas campur yang diharapkan ramah lingkungan dan bersifat renewable. Hal yang dirasa kurang dalam perbaikan mutu pembakaran dapat diperbaiki dengan penggunaan zat aditif. Pengujian dilakukan secara nyata. Dengan mengamati kinerja motor bensin dua langkah tipe KW6-R berbahan bakar campur minyak atsiri dan aceton pada mesin uji dynotest. Luaran berupa data yang terekam dari alat uji. Berupa nilai daya (aktual dan koreksi), torsi, kerugian daya, putaran mesin, serta kecepatan (berdasar putaran roda penggerak motor). Hasil pengujian a. Pada pengujian keadaan standart ( menggunakan sistem lumas injeksi dengan pelumas semi sintetis) diperoleh daya maksimal 26,4 HP (pengulangan 3), kerugian daya 9,7 HP @ 121 km/h / 5460 (1/min) (pengulangan 2), serta torsi 40 kgm (wheel) @ 66 (km/h) / 2946 (1/min)(pengulangan 3); b. Pada pengujian berbahan bakar campur pelumas sintetis diperoleh daya maksimal 27,4 HP (pengulangan 2), kerugian daya 6,4 HP @ 121 km/h / 5424 (1/min) (pengulangan 2), serta torsi 39 kgm (wheel) @ 33 (km/h) / 1500 (1/min)(pengulangan 1); c. Pada pengujian berbahan bakar campur minyak atsiri 5ml dan aceton 5 ml diperoleh daya maksimal 28,4 HP (pengulangan 2), kerugian daya 4,4 HP @ 106 km/h / 4742 (1/min) (pengulangan 2), serta torsi 47 kgm (wheel) @ 47 (km/h) / 2119 (1/min)(pengulangan 3); d. Pada pengujian berbahan bakar campur minyak atsiri 10ml dan aceton 5 ml diperoleh daya maksimal 27,8 HP (pengulangan 3), kerugian daya 4,3 HP @ 73 km/h / 3296 (1/min) (pengulangan 3), serta torsi 76 kgm (wheel) @ 20 (km/h) / 907 (1/min)(pengulangan 3); e. Pada pengujian berbahan bakar campur minyak atsiri 15ml dan aceton 5 ml diperoleh daya maksimal 27,8 HP (pengulangan 1), kerugian daya 5,6 HP @ 115 km/h / 5182 (1/min) (pengulangan 1), serta torsi 71 kgm (wheel) @ 20 (km/h) / 907 (1/min)(pengulangan 1). Dari hasil pengujian nampak bahwa daya terbesar dapat diraih pada campuran bahan bakar minyak atsiri 5ml dan aceton 5ml sebesar 28,4 HP dengan torsi 47 kgm @ 47 (km/h) 2119 (1/min). Sedangkan torsi maksimum dapat diraih pada campuran bahan bakar minyak atsiri 10 ml dan aceton 5ml dengan 76 kgm (wheel) @ 20 (km/h) / 907 (1/min). Kata kunci: minyak jarak, aseton, uji bahan bakar

Abstract

Measuring the performance of language is a challenge to the education system in every education level. In measuring the performance of language, the analysis should be conducted in each individual to find the best understanding of the learners’ real performance of language ability on language learning. Conventionally, the test evaluator is evaluating the achievement by using a one-time test to analyze the language achievement in a time-saving and simple evaluation. While the conventional evaluation method seems to be practical, the result of the evaluation is only revealing the language achievement on the day the test is administered by ignoring the dynamics of the language acquisition of the learners. the research is dealing with implementing a new method in understanding language acquisition of the performers. The research employs descriptive-quantitative method and gathering the data in a series of 4 times data collections by using specific task to the students in English department of UMM as the purposively selected subjects. Following the data collection, the analysis is conducted in a series of 4 analyses to show the ‘movement’ or the dynamics of the language performance and use.Based on the result, the research validates the dynamics system analysis as a new method of measuring language performance in detail.
