Abstract

Sago liquid waste is rich in micro and macro nutrient that can be used for growing Chlorella sp. To understand the effectiveness of the waste as a nutrient source to grow Chlorella sp., a study was conducted from November – December 2016. Different amount of sago liquid waste was added to 3L of peat water, they were P0(0%), P1(5%), P2(15%) and P3 (25%) of peat water volume. The Chlorella sp. was culture for 11 days. Parameters measured were the abundance and biomass of Chlorella sp., nitrate and phosphate concentration, dissolved oxygen, pH and temperature. Results shown that the best growth of Chlorella sp. was in the P1(5%), the abundance was 2,768,000 cells/ml and the biomass was 0.28 g/L. During the research, the nitrate and phosphate concentration reduced, from 0.5575 to 0.2540 mg/L and from 0.9358 to 0.3142 mg/L respectively. This fact indicates that the nutrients have been used for Chlorella sp. growth. Based on data obtained, it can be concluded that the sago liquid waste can be used as nutrient source for growth Chlorella sp. Keywords : Sago liquid waste, nutrient, growth, Chlorella sp.

Abstract

In the Koto Panjang Dam, the water quality is affected by pollutant input originated from activities conducted around and in the dam, such as illegal logging, boat activities, households and floating net cage fish culture. To understand the water quality in general, a research was conducted from January 2016. This research aims to determine the water quality of the reservoir based on physical, chemical parameters and saphrobic coefficient (X). There were three stations, 3 sampling points/ station. Water samples were taken 3 times/ week. Water quality parameters measured were water temperature, turbidity, brightness, TSS, pH, DO, BOD5, nitrate and phosphate. While plankton were identified based on Yunfang (1995) and Hiroyuki (1977). Results shown that there were 7 classes of plankton present, namely Cyanophyceae (7 genus), Chlorophyceae (8 genus), Bacillariophyceae (8 genus), Dinophyceae (1 genus), Euglenophyceae (2 genus), Rotifer (1 genus) and Ciliate (1 genus). Water quality parameters are as follows: temperature : 29 – 30 0C, turbidity: 1.6 – 2.7 NTU, brightness : 120 – 145,5 cm, TSS : 26 – 42 mg/L, pH 5 – 6, DO : 5.3 – 6 mg/L, BOD5 : 3.2 – 3.62 mg/L, nitrate : 0.058 – 0.065 mg/L and phosphate : 0.030 – 0.039 mg/L. The saphrobic coefficient (X) of the water was 0.71-0.80 and it means that the Koto Panjang Dam is lightly polluted (mesosaphrobic phase).Keywords : Koto Panjang Dam, fish cage, mesosaphrobic phase, Saphrobic Coefficent

Abstract

The purpose of this research was to review the quality of dried selais fish (Kryptopterus lais) by soaking of chitosan solution during room temperature storage. The methode used in this reseach was experimental methode by soaking of dried selais fish (Kryptopterus lais) with 3 % of chitosan solution concentration for 30 minutes of soaking time (K1) and without soaking of chitosan solution (K0), during 0, 7, 14 days of room temperature storage. The parameters tested were Total Plate Count, organoleptic analysis (appearance, aroma, texture) and chemical analysis. The result showed that the treatment was significant different to the quality of dried selais fish (Kryptopterus lais) during room temperature storage. The K1 treatment tend to have higher average than K0 treatment for all of parameters tested (Total Plate Count, organoleptic analysis (appearance, aroma, texture), and chemical analysis.Keywords : Chitosan, Kryptopterus lais, Quality
