Abstract             Rasbora caudimaculata is a type of freshwater fish that inhabits the Tanjung Kudu and the Teluk Petai Lakes, Kampar Regency. A study aims to understand the type of food in the stomach of the fish was conducted in October – January 2021. Samplings were carried out 4 times, once/2 weeks. The fish was caught using nets with mesh size 0.5 inch and 1 inch. There were 321 fishes (169 fishes from the Tanjung Kudu Lake and 152 fishes from the Teluk Petai Lake).  There were 58 fishes with empty stomach and they cannot be analyzed. The analysis of stomach content was conducted using a volumetric method. The stomach content data obtained were used as a basis to calculate the Preponderance Index (PI). The types of food present in the fish’s stomach from both sampling areas were similar. The main food of R. caudimaculata from both   lakes is insects, PI 55% from the Tanjung Kudu Lake and PI 46% from the Teluk Petai Lake. The complementary foods were phytoplankton (Bacillariophyceae, Chlorophyceae, Cyanophyceaea, Euglenoidea, Trebouxiophyceae, Xanthophyceae dan Zygnematophyceae) and rotifers. R. caudimaculata has viliform teeth and short firm gill rakers. The length of intestine was 1.2 times of total length. Data obtained indicate that R. caudimaculata is an omnivorous fish.Keywords: Oxbow lake, Feeding habit, Omnivorous fish, Preponderance Index

Abstract

ABSTRACT               Fuel oil is the aspect that is most prepared before going to sea. In meeting the demand for fluctuating fuel oil demand, prediction is needed, so that it can predict the supply to meet the required amount. This study aims to predict the amount of fuel oil inventory each month by using fuzzy logic to meet the needs of fishing supplies.               The results showed that the prediction of fuel oil had increased compared to the supply of fuel oil in the previous year. The total supply of fuel oil in 2019 was 1866 tons, while the prediction of fuel oil inventories for 2020 was 1974 tons. The results of this fuel oil prediction were tested using MAPE (Mean Absolute Presentage Error) to get the accuracy value. The MAPE value obtained is 7.68% which is considered accurate and acceptable to determine the prediction results of fuel oil inventories.Keywords: Prediction of fuel oil inventory, fishing supplies, fuzzy logic
