Abstract

El Niño 2015 is one of the strongest El Niño. Drought stress due to El Niño could affect oil palm performances. This study was conducted to determine rainfall pattern and oil palm performance in Sumatra and Borneo Island during El Niño 2015. Data employed in this study is monthly rainfall data, Southern Oscillation Index (SOI) January-December 2015, andoil palm performances. Pearson correlation between SOI and rainfall data was used to analyze rainfall pattern, while oil palm performances were observed based on morphological conditions. Result shows that southern part of Sumatra and mostly part of Borneo suffer from more dry spell, dry month, and water deficit such as 37-133 days, 3-5 months, and 349-524 mm respectively. Analysis of rainfall pattern shows that Jambi, South Sumatra, Lampung, Central, South, and East Borneo are significantly (r ≥ +0,60) affected by El Niño 2015. Oil palms in southern part of Sumatra and mostly part of Borneo are suffer from drought stressmarked by the emergence of more than two spear fronds, appearing of many male flowers, malformations on bunches, fronds tend to hanging down, and lower fronds tend to dry.

Abstract

Mixing Crude Palm Oil (CPO) with high and lower Free Fatty Acid (FFA) is a technique to reduce FFA in CPO. Avocado Seeds Extract (ASE) was expected to reduce the FFA. This study was conducted to test the ability of ASE on reducing ALB in CPO. The variable in this study is ASE solution (0-50 ml). The whole treatment were conducted at same level of o temperatur 60 C, stirring speed (400 rpm) and reaction time (60 minutes). The research was employed non factorial Completely Randomized Design. Statistical analysis was performed using F Test along with Duncan Test. The results showed that addition of ASE can reduce FFA. The results of F Test showed that the addition of 25 ml ASE is the most effective for reduction ALB content (4.65 % to 0.22 %) in CPO.
