Pengaruh Fluktuasi Harga Minyak pada Ekspor Minyak Mentah Negara-Negara Wilayah OPEC (Periode 1970 – 2005)

This research pressures to export demand of opec crude oil. It concern primarily on the impact of price oil shock toward OPEC crude oil export. Ordinary Least Square (OLS) is not proven accurately to analyze volatile phenomenon of OPEC export demand of crude oil. Otherwise, General Autoregressive Conditional Heteroskedastic (GARH) and specifically Exponential GARCH give practical and logical model to be applied. It shows that structural break occur in price oil variable and then impact to volatile of crude oil export. Several important world events create structural break and this “bad news” has significant impact to instability of oil price. This result gives also that nominal crude oil price adjusted for exchange rates and demand export of Non-OPEC crude oil have negative impact, and OPEC proven crude oil reserve and Exports of refined products by OPEC have positive impact to OPEC crude oil export

Recent Advances in Biofuel Cell and Emerging Hybrid System

The present paper reviews the recent development of biofuel cell. Due to its renewable nature and milder operating conditions compared to conventional fuel cell, the electrochemical system has been extensively studied. However, major problems associated with this type of electrochemical system remain an intimidating challenge, the utmost being the low power output and stability of biocatalyst being used. Various attempts have been made to overcome these problems, some are reviewed here. The authors suggest a new direction in solving these problems by using hybrid system i.e. metal biofuel cell. The new hybrid system developed is of lower cost, less complex, higher OCV and greater power output
