<![CDATA[This research was motivated by the large number of consumer requests for mechanics in workshops to replace the radiator coolant in diesel engines with reguler water. This research used an experimental research approach. The experimental research was often used to find the effect of existing variable and to test the hypotheses. Based on the results of testing and data analysis that have been carried out can be seen: there was an average decrease in the temperature of the cooling media from the engine due to using the cooling media from the manufacturer, a decrease in the rate of heat dissipation between reguler water and Prestone on each rotation with an average of 4.97%, the water with TOP 1 Coolant 5.11% and the water with Toyota SLCC at 6.64%. Based on the analysis of research data and statistical tests, it was concluded that the use of cooling media from the manufacturer can increase the heat transfer coefficient of the working fluid of the radiator, so that it can reduce the engine heat level and increase the rate of coolant heat dissipation. Penelitian ini dilatarbelakangi oleh banyaknya permintaan konsumen kepada mekanik di bengkel untuk mengganti air radiator pada mesin diesel dengan air biasa Penelitian ini digolongkan pada penelitian pendekatan eksperimen. Penelitian eksperimen sering digunakan untuk mencari pengaruh di antara variabel-variabel yang ada serta untuk pengujian hipotesis. Hasil pengujian dan analisis data yang telah dilakukan dapat diketahui: Terdapat rata-rata penurunan suhu media pendingin dari mesin akibat menggunakan media pendingin asal pabrikan, penurunan laju pembuangan panas antara air biasa dengan Prestone pada masing-masing putaran dengan rata-rata 4,97%, air dengan TOP 1 Coolant 5,11% dan air dengan Toyota SLCC sebesar 6,64%. Berdasarkan analisis data penelitian dan uji statistik yang dilakukan disimpulkan bahwa penggunaan media pendingin asal pabrikan dapat memperbesar koefisien perpindahan panas fluida kerja radiator sehingga dapat menurunkan tingkat panas mesin dan meningkatkan laju pembuangan panas cairan pendingin]]>

<![CDATA[Switching from fossil fuels to alternative fuels requires adjusting several engine parameters to avoid a decrease in engine torque and power. This happens because of the different properties of different fuels. One of the parameters that must be set is the compression ratio. This study aims to determine the effect of increasing the compression ratio on the torque and power of the Honda CB 150R engine using 85% bioethanol (E85) as fuel. The research method used an experimental method with 2 types of fuel and variations in the compression ratio. From the research results, it can be seen that the torque and power using E85 fuel have increased respectively by 1.08% and 1.5% when compared to the standard compression ratio using fossil fuels. Pergantian bahan bakar dari fosil ke bahan bakar alternatif membutuhkan pengaturan pada beberapa parameter engine untuk menghindari terjadinya penurunan pada torsi dan daya mesin. Hal ini terjadi karena perbedaan dari properties bahan bakar yang berbeda. Salah satu parameter yang harus di atur adalah rasio kompresi. Penelitian ini bertujuan untuk mengatahui pengaruh dari peningkatan rasio kompresi terhadap torsi dan daya engine Honda CB 150R menggunakan bahan bakar bioetanol 85% (E85). Metode penelitian menggunakan metode eksperimen dengan 2 jenis bahan bakar dan variasi pada rasio kompresi. Dari hasil penelitian terlihat bahwa torsi dan daya dengan menggunakan bahan bakar E85 mengalami peningkatan masing-masing sebesar 1,08 % dan 1,5 % jika dibandingkan dengan rasio kompresi standard menggunakan bahan bakar fosil.]]>
