Pengaruh Elektrolisis Terhadap Rendemen Minyak Jarak Yang Dihasilkan Pada Proses Pembuatan Biodiesel

The use of jatropha oil as a source of raw material for making biodiesel is needed in order to decrease the production cost of biodiesel, since jatropha oil is categorized as non edible fat. In this research, the biodiesel production process by using an electrochemical reactor has been done. At the beginning of treatment, carried out the hydrolysis of oil by using HrS04 with acid and oil volume ratio is 1: 20. At follow-up treatment, carried out the decarboxylation via electrolysis. This process is done by varying the voltage of 0 V, 10 V,20 V,30 V,the variation of the concentration of 0.5 M acetic acid. 1 M, 1.5 M, as well as the distance between the electrodes in the reactor 5em and 10 em. From the experiments shown that electrolysis with voltage parameters, acidic electrolyte solution. and electrode spacing affects the yield of decarboxylation process. Electrolysiswith 1.5 M acetic acid concentration and voltage of 30 volts per cent obtained the highest biodiesel yield of compound that is 70.432% in the reactor with inter-electrode distance of 5cm. While in the reactor with inter-electrode distance of 10 cm. thehighest yield was 53.372% by reacting the oil with 1.5 M acetic acid and voltage 30 Volt

Al-Qur’an: Linguistics and Culture Involve In Research and Other Fields of Science

Linguistics is the Science that We Study about the Languages whether Specific or Universal Languages, or whether Verbal or non Verbal Skills, and It also encompasses some Branches of Linguistics, such as Phonology, Morphology, Syntax, Semantics, etc., including Culture and other fields of Science and Technology. In short word, No Language, No Activities of Human in the World, No Language, No development of Culture, Science and Technology. Language is the Key of Human Life for all Activities in the World

GLOBALIZATION TOURISM PROMOTION FOR TOURISM PLACES TG.PINANG AS THE WORLD TOURISM

Tg.Pinang as the Capital City of Riau Archipelago particularly and other its areas, generally have a lot of potencies of Tourism Objects whether Natural Objects, Cultural Objects, Historical Objects, Sea and Beach Objects, Home Industry, etc. Therefore, because of these, it is needed to be maintained, built, developed, innovated, and promoted to Local, National, Asean, Asia, and Global Promotions, so that those can be known or be famous for Global Community. These assets can also be deficits of Local, National, and the welfare of Society.Consequently, to do these as good as possible, it is needed, such as good promotion, infrastructures, services, and exchange exhibitions in Local, National, Asean, Asia, and Global Communities
