Abstract
Biodiesel memiliki stabilitas penyimpanan yang rendah sehingga mudah terdegradasi dalam kondisi penyimpanan. Terdapat 4 penyebab degradasi pada biodiesel dapat terjadi yaitu oksidasi dengan oksigen, hidrolisis oleh air, degradasi pada temperatur tinggi dan aktivitas mikroganisme. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan silica gel dan serbuk iron powder dalam menghambat laju degradasi biodiesel. Metode yang digunakan dalam penelitian ini adalah percobaan penyimpanan biodiesel selama 8 minggu. Penelitian ini, digunakan pengujian angka asam dan uji TPC (Total Plate Count) bakteri sebagai parameter pengukuran laju degradasi biodiesel. Dari penelitian ini, diketahui bahwa penggunaan silica gel dan iron powder dapat mengurangi laju degradasi biodiesel dan dapat mengurangi pertumbuhan bakteri. Hal ini dibuktikan dengan penurunan laju degrades ipada tangki dengan komposisi 3,2 g/l silica gel dan 2,4 g/l iron powder sebesar 46 % dibandingkan dengan tangki 7 (kontrol) . Dalam pengujian jumlah bakteri diketahui bahwa pada tangki dengan komposisi 3,2 g/l silica gel dan 2,4 g/l iron powder, mengalami penurunan sebesar 99,8%. sedangkan pada tangki 7 terjadi peningkatan jumlah bakteri sebesar 37,6%.

Biodiesel has low storage stability so that it is easily degraded under storage conditions. There are 4 things that can cause degradation in biodiesel namely oxidation with oxygen, hydrolysis by water, degradation at high temperatures and microorganism activity. This study aims to determine the effect of using silica gel and iron powder powder to inhibit the degradation rate of biodiesel. The method used in this study was a trial of biodiesel storage for 8 weeks. In this research, acid number testing and bacterial Total Plate Count (TPC) test will be used as a parameter to measure the degradation rate of biodiesel. From this study, it is known that the use of silica gel and iron powder powder reduces the rate of degradation of biodiesel and can reduce bacterial growth. This is evidenced by the decrease in degrades rate in tanks with a composition of 3.2 g / l silica gel and 2.4 g / l iron powder by 46% compared to tank 7 (control). In testing the number of bacteria it is known that in tanks with a composition of 3.2 g / l silica gel and 2.4 g / l iron powder, a decrease of 99.8%. while in tank 7 there was an increase in the number of bacteria by 37.6%.
