The impact of oil price movement are negative and statistically significant for most of sector indices except finance and consumer goods, miscellaneous sectors. Hence, those sectors are appropriate components of sector index portfolio to dampen the oil risk. In contrast, the impacts of trading volumes are positive and statistically significant for all sector indices. Hence, The aggregated impact of both factors will be eliminated each other in several sectors.

Akankah Berhasil Swasembada Gula Tahun 2014?
The article aims to analyze the government program of regarding self sufficiency of sugar in year 2014. Will it be a success or it will be unrealized plan? The writer believes that such plan will be difficult to carry on due to : 1) the current available land is only 25,000 ha, where as the self suffiency program requres 350,000 ha, a huge gap from the requirement . 2) market only absorb Rp 1.3 trillion out of Rp 4.9 trillion loan for sugar factory revitalization provided by the government. 3) declining in sugar price has divert farmerâ€™s land from producing sugar to other commodities, resulting in higher import of sugar. Should the government insisted in executing this plan, it can only be done by importing raw sugar as input to boost up the production. However, it will cause a major suffering for our local farmers. Hence, by implementing the plan, it seems that the government chooses to protect consumers instead of farmers.
KEY WORDS: Sugar, self sufficiency of sugar
