Abstract
Menipisnya cadangan minyak bumi menjadi salah satu masalah utama yang dihadapi diberbagai negra. Oleh sebab itu perlu adanya solusi salah satunya untuk beralih menuju bahan bakar alternative yang terbarukan seperti penggunaan biodiesel pada diesel engine. Biodiesel merupakan bahan bakar yang berasal dari tumbuh-tumbuhan seperti kelapa sawit yang bersifat renewable namu perlu dilakukan kajian yang lebih mendalam terhadap performa dan emisi yang dihasilkan dari biodiesel. Pada penelitian akan dilakukan eksperimen dengan bahan bakar B20 dan B30 dengan memdandingkan performa pada kondisi STD (0% EGR), EGR, dan selanjutnya EGR akan dilakukan optimalisasi dengan menambahkan pengingin pada EGR atau bias disebut dengan cold EGR dengan melakukan variasi suhu pada intake dibawah suhu intake saat belum terpasang cold EGR. Dari hasil penelitian yang sudah dilakukan diketahui bahwa pemasangan cold EGR dapat meningkatkan daya namun cenderung berbanding lurus dengan konsumsi bahan bakar. Untuk B30 titik daya tertinggi didapat pada suhu intake sebesar 40°C pada bukaan katup EGR 20%, sedangkan Untuk B20 titik daya tertinggi didapat pada suhu intake sebesar 40°C pada bukaan katup EGR 10%. Untuk emisi NOx B30, titik kadar NOx terendah didapat pada suhu intake 36°C untuk bukaan katup EGR 10% dan 20% dan untuk bukaan 30% terdapat pada suhu intake sebesar 39°C. Sedangkan Untuk emisi NOx B20, titik kadar NOx terendah didapat pada suhu intake 38°C untuk bukaan katup EGR 10% dan 40°C untuk bukaan katup 20% dan untuk bukaan 30% terdapat pada suhu intake sebesar 43°C

The depletion of petroleum reserves is one of the main problems faced in various countries. Therefore one solution is needed to switch to alternative renewable fuels such as the use of biodiesel in diesel engines. Biodiesel is a fuel derived from plants such as palm oil that is renewable but needs to be carried out a deeper study of the performance and emissions produced from biodiesel. In this study, experiments will be conducted with B20 and B30 fuels by comparing the performance under STD conditions (0% EGR), EGR, and then EGR will be optimized by adding coolant to the EGR or can be called cold EGR by varying the temperature at the intake below the temperature intake when cold EGR is not installed. From the results of research that has been done, it is known that the installation of cold EGR can increase power but tends to be directly proportional to fuel consumption. For B30 the highest PowerPoint is obtained at an intake temperature of 40 ° C at 20% EGR valve openings, while for B20 the highest PowerPoint is obtained at an intake temperature of 40 ° C at 10% EGR valve openings. For NOx B30 emissions, the lowest NOx level is obtained at the intake temperature of 36 ° C for 10% and 20% EGR valve openings and for the 30% aperture is at the intake temperature of 39 ° C. Whereas for NOx B20 emissions, the lowest NOx level is obtained at an intake temperature of 38 ° C for 10% EGR valve openings and 40 ° C for 20% valve openings and for 30% openings at an intake temperature of 43 ° C
