| Abstrak (Bhs. Indonesia) | Katalis heterogen merupakan salah satu alternatif yang dapat mengatasi kekurangan dari penggunaan katalis homogen dalam proses transesterifikasi biodiesel. Katalis heterogen dapat dengan mudah dipisahkan dari campuran reaksi sehingga dapat digunakan kembali, mengurangi biaya produksi, dan meminimalisir limbah yang berdampak negatif bagi lingkungan. Saat ini banyak dikembangkan katalis heterogen dari limbah industri dan sumber terbarukan. Tujuan penelitian yaitu: 1)Mengetahui pengaruh penggunaan berbagai jenis katalis heterogen terhadap kualitas biodiesel dari minyak kelapa sawit. 2)Mengetahui karakteristik biodiesel yang dihasilkan dari penggunaan berbagai jenis katalis heterogen. 3)Mengetahui perlakuan jenis katalis heterogen dan konsentrasi katalis heterogen terhadap kualitas biodiesel yang dihasilkan. Metode penelitian menggunakan rancangan acak lengkap (RAL) dengan dua faktor yaitu jenis katalis heterogen (Abu kulit kakao segar, kakao busuk, kola, dan kemiri sunan) dan konsentrasi katalis (2% dan 3%) yang diulang tiga kali, selanjutnya dilakukan analisis data menggunakan uji ANOVA dan dilanjutkan dengan uji DMRT. Proses transesterifikasi menghasilkan rendemen sebesar 81,8%- 92,4%. Hasil variasi perlakuan jenis katalis berpengaruh terhadap rendemen yang dihasilkan. Uji DMRT diperoleh hasil bahwa jenis katalis heterogen abu kulit kakao busuk berbeda nyata dengan katalis heterogen abu kulit kakao segar, kola dan kemiri sunan, sedangkan katalis heterogen abu kulit kakao segar, kola dan kemiri sunan tidak saling berbeda nyata. Hasil pengujian nilai densitas dan viskositas memenuhi syarat dan mutu biodiesel menurut SNI-7182-2015, sedangkan pengujian kadar air dan angka asam masih belum memenuhi syarat mutu biodiesel. Jenis katalis heterogen terbaik yang digunakan dalam pembuatan biodiesel yaitu katalis heterogen abu kulit kemiri sunan karena menghasilkan rendemen tertinggi sebesar 92,4%. |

| Abtrak (Bhs. Inggris) | Heterogeneous catalyst is an alternative that shortcomings of using homogeneous catalysts in biodiesel transesterification process. Heterogeneous catalysts can be easily separated from the reaction mixture so that they can be reused, reducing production costs, and minimizing waste that has a negative impact on the environment. Currently, many heterogeneous catalysts have been developed from industrial waste and renewable sources. The research objectives were: 1) Determine the effect of using various types of heterogeneous catalysts on the quality of biodiesel from palm oil. 2) Knowing characteristics of biodiesel produced from the use of various types of heterogeneous catalysts. 3) Knowing the treatment of heterogeneous catalyst types and the concentration of heterogeneous catalysts on the quality of biodiesel produced. The research method used a completely randomized design (CRD) with two factors, the type of heterogeneous catalyst (fresh cocoa husk ash, rotten cocoa, kola, and kemiri sunan) and catalyst concentration (2% and 3%) which were repeated three times, then data analysis was carried out. using the ANOVA test and continued with the DMRT test. The transesterification process resulted in a yield of 81.8% - 92.4%. The results of variations in the type of catalyst treatment affect the yield produced. The DMRT test showed that the heterogeneous catalyst types of rotten cocoa husk ash were significantly different from the heterogeneous catalysts of fresh cocoa husk ash, kola and kemiri sunan, while heterogeneous catalysts of fresh cocoa husk ash, kola and kemiri sunan were not significantly different from each other. The results of testing the density and viscosity values meet the requirements and quality of biodiesel according to SNI-7182-2015, while testing the water content and acid number still does not meet the biodiesel quality requirements. The best type of heterogeneous catalyst used in biodiesel production is the heterogeneous catalyst of kemiri sunan ash because it produces the highest yield of 92.4%. |
