Abstract

Use of fuel oil is increasingly high, but the problem is not in line with the production of fuel oil which is increasingly lower, so to anticipate and meet the fuel needs of the growing diesel engine, it requires a search and research on alternative fuels. To slow and reduce dependence on petroleum fuels is one of them is the use of biodiesel fuel. Biodiesel is a fuel alternative to petroleum. The use of biodiesel can be blended with petroleum diesel (diesel). Biodiesel is generally easy to use, is biodegradable, nontoxic, and free of sulfur and aromatics. Making biodiesel at this research as a form of anticipatory problem. Research on effects of the volume of catalyst in the manufacture of biodiesel by transesterification process that has been done to produce optimum conditions just as the use of stearin as much as 500 ml, catalyst volume of 25 ml and 175 ml using transesterification temperature between 60-65°C for one hour so that the obtained yield 65.42%, density 0.875 g/ml, pH 6.95, water content 0.014%, flash point 179oC, Calorific Value of 6318 cal/g and cetane number of 64.5. This shows that the more volume of catalyst and methanol is added to the product yield will be higher but the temperature and time used must match the type of solvent and catalyst when the transesterification.

Abstract

Penambahan senyawa polimer, seperti karet alam (SIR 20) dan karet sintetis (Ban bekas) ke dalam Aspal SRC (Singapore Refining Company) Pen. 60/70, pada dasarnya bertujuan untuk menghasilkan Aspal Karet dengan keelastisan yang baik. Pada penelitian ini, jumlah penggunaan karet alam (SIR 20) yang ditambahkan ke dalam 300 gram aspal SRC divariasikan sebanyak 0, 5, dan 10 gram, sedangkan jumlah karet sintetis (Ban bekas) divariasikan sebanyak 100, 150, dan 200 gram. Senyawa polimer di dalam pembuatan Aspal Karet ini berperan sebagai bahan aditif dalam peningkatan mutu aspal. Aspal Karet dengan variasi masing-masing komposisi di dalam penelitian ini, dilakukan analisis terhadap parameter penetrasi, daktilitas, berat jenis, titik nyala, dan titik lembek. Adapun hasil dari penelitian ini menunjukkan bahwa hasil analisis parameter dari variasi komposisi tersebut sangat jauh dari analisis parameter Aspal Standar, sehingga Aspal Karet dengan variasi komposisi tersebut tidak memenuhi persyaratan pengujian Aspal Standar dengan metode SNI. Hasil analisis Aspal Karet yang memiliki sifat-sifat fisik yang lebih baik adalah Aspal Karet dengan komposisi karet alam (SIR 20) sebanyak 10 gram dan karet sintetis (Ban bekas) sebanyak 100 gram menghasilkan angka penetrasi sebesar 204,4 mm, daktilitas 30,5 cm, berat jenis 1,079 gr/cc, titik nyala 211oC, dan titik lembek 27,6oC.
