Abstract

One alternative of fresh milk preservation is by adding sugar that derived from the hydrolysis process of blue taro tuber. The aim of this study was to examine the quality of fresh milk after the addition of oligofructose syrup. The study was carried out from April to June in 2013. Based on the ANOVA test, it was known that the concentration of oligofructose syrup influenced the increase of proximately test, total number of bacteria, and reduction time of milk. The protein content of milk increased to 0.25% after being added by oligofructose syrup with 20% concentration, and then it became 3.95 %. The lactose content increased to 2.05% after being added by oligofructose syrup with 40% concentration, and then it become 6%. The highest increment of milk acidity occurred over milk by adding 40% of oligofructose syrup. Furthermore, 40% milk fat and oligofructose syrup decreased to 2.40%, which it became 2%. Total number of milk bacteria decreased to 23x103 CFU/ml after being added by 40% oligofructose syrup, but then it become 26x103 CFU/ml. In this study, no indication of coliform was found in all milk samples. Best time of reducing bacteria occured over milk added 40% syrup is 634 minutes.

Abstract

Sungai Jawi and Sungai Raya Dalam canals were frequently benefited by communities for a variety of daily necessities. These activities led to changes in water conditions and disrupt community structure in it. The purpose of this study was to determine the periphytic micro-algae community structure and the level of water pollution in Sungai Jawi and Sungai Raya Dalam canals. The samples were collected in Sungai Jawi and Sungai Raya Dalam canals. The determination of stations was based on environmental setting. Each canal was divided into 4 stations with 3 points laying substrate. The results showed that the periphytic micro-algae were from 3 divisions and 3 classes, namely Chrysophyta (Bacillariophyceae), Chlorophyta (Chlorophyceae), and Cyanophyta (Cyanophyceae). There were 26 genera of periphytic micro-algae in Sungai Jawi Canal and 25 genera of periphytic micro-algae in Sungai Raya Dalam Canal. Total abundance of periphytic micro-algae in Sungai Jawi Canal was 378,15 - 651,86 ind/cm2 and in Sungai Raya Dalam was 488,50 - 657,13 ind/cm2. The highest abundance was found in the both canal from the Bacillariophyceae class, Navicula genus. Shannon-Winner diversity index on Sungai Jawi and Sungai Raya Dalam canals was classified as middle category (2,0393 - 2,5690). Pollution level that occurred on both canal was still relatively mild.

Abstract

Phytoplankton plays an important role in aquatic ecosystem as a primary producer. This study aims to determine the genera, abundance and horizontal distribution of phytoplankton and to measure the physical and chemical characteristics in the estuary of Kakap River. The study was carried out between December 2013 and May 2014. Phytoplankton samples were taken from five stasions that were determined based on the differences in the environmental conditions by Adaptive Cluster Sampling Method. The samples of phytoplankton were taken when the river water was in a tidal conditions by plankton net. The composition of phytoplankton found in estuary of Kakap River composed of 7 divisions, 7 classes and 42 genera. The highest phytoplankton abundance found at high tides were 42,825 ind/L and 35,769 ind/L respectively. The highest abundance phytoplankton was found from Bacillariophyceae (43,329 ind/L). Horizontal distribution of phytoplankton showed that the further away from the area of river basin, more abundance and more diverse of phytoplankton. Based on the value of Diversity Index (H’) (3.006 - 3.3489), Dominance Index (D) (0.0473 – 0.0613) and Evennes Index (E) (0.7118 – 0.8548), the estuary of Kakap River was in stable condition with high diversity. Characteristics of physial and chemical factors in the river were able to support the life of phytoplankton.
