Minyak Biji Nyamplung (Calophyllum inophyllum) Dengan Etanol

Abstract

A study has been conducted on the transesterification of Calophyllum innophyllum seed oil with ethanol. The purpose of this research is to determine the comparison of concentration of phosphoric acid used to remove the gum on the oil, ester content is produced in the process of transesterification with ethanol, the ester yield obtained after the final stage of the transesterification process, the viscosity of the biodiesel produced, moisture content of biodiesel is produced, and density of biodiesel was produced. This research is taken based on consideration production biodiesel by direct transesterification process. Based on research result of good phosphoric acid concentration used to remove oil gum is 85%, volume of biodiesel produced at transesterification equal to 150 mL with yield 80,89%, biodiesel quality parameter measured that viscosity = 0,05 mm2 / s not fulfill Indonesian National Standart (INS), moisture content = 0.045 meets the INS and the density = 0.881 g / cm3 meets the INS

Pengaruh Katalis Zeolit Alam Ende Terhadap Kecepatan Aduk Dan Waktu Optimum Dalam Esterifikasi Biodiesel Dari Minyak Nyamplung

“…(Muderawan & Daiwataningsih, 2016). Fasa cair yang terbentuk pun akan terbagi karena perbedaan sifat polar dari minyak dan metanol (Rezki & Haetami, 2017). Pada keadaan awal tersebut laju reaksi berjalan lambat karena transfer massa dari zat yang bersifat heterogen relatif rendah.…”

Etnosains Tumbuhan Nyamplung (Chalophyllum inophillum L.) dalam Tradisi Masyarakat Sasak

“…Menurut hasil penelitian (Rezki et al, 2017), minyak Nyamplung hasil ekstraksi mekanis yang ditransesterfikasi dengan etanol menghasilkan bahan biodiesel dengan rendemen 80,89% dengan viskositas 0,05 mm 2 /s dengan kadar air 0,045% dan densitas 0,881 g/mL. Asam posfat 85% diperlukan untuk menghilangkan oil gum secara maksimal.…”
