Abstract

Ponds in Indonesia, especially in Brebes district, usually produce export-oriented fishery products that have high economic value. One of the fishery products currently being developed is vannamei shrimp (Litopenaeus vannamei). The presence of plankton in the water can be used as an indicator of water quality because it is strongly influenced by water quality. The purpose of this study was to estimate the abundance and stability of pond water from biological measurements (variation, diversity, and dominance of plankton) in the Sawojajar vannamei shrimp ponds. The method used is quantitative and descriptive at random. The results showed that the value of the abundance of phytoplankton ranged from 3451 to 6895 cells/mL, with the highest relative abundance being the type of Bacillariophyta. Meanwhile, the abundance of zooplankton ranged from 45 to 525 ind/mL, with Rotifera having the highest relative abundance. The diversity index status (H') is moderate, the uniformity index (E) is high, and the dominance index is low. Phosphate and COD found were high, as were other water qualities such as DO and temperature. Optimum pH, salinity, and brightness

Abstract

Lebak Petai is a place for fishing by fishermen and auction holders. A continuous fishing system can affect the diversity of fish in these waters. The aims of this research was to identify the type of fish, length and weight of the fish, analyze the species diversity index, uniformity index, relative abundance, dominance and water quality. This research was carried out from July to September 2021. Sampling took place in Lebak Petai, Pedamaran sub-district, Ogan Komering Ilir district, using three sampling stations. The results of the research showed that there were 530 types of fish caught in Lebak Petai, consisting of 13 types of fish belonging to 9 families. The largest fish in length and weight was the Barbonymus schwanenfeldii fish, namely 12-25.5 in length and 21.11- 188.92 in weight, while the lowest fish was the Elops mchnata fish, namely 9-10.5 in length and 5.58-8.5 in weight. The diversity index was classified as medium, namely 2.33-2.51, the uniformity index was classified as uneven, namely 0.92-0.98, the highest relative abundance in Lebak Petai is Trichogaster pectoralis, and there was no dominant fish, namely between 0.9-0.11. The water quality during the research in Lebak Petai, Ogan Komering Ilir Regency was still within a suitable range for fish life.

Abstract

Preservatives are becoming one of the more frequently used food additives. Natural preservatives are needed to replace the use of formalin, which is hazardous to human health. One of the natural preservatives that can be utilized is chitosan solution combined with rice husk liquid smoke. The chitosan solution combined with rice husk liquid smoke with the addition of glucose and the sterilization process will produce a Maillard reaction that functions to increase the effectiveness of antibacterial properties. The research objective was to determine the level of browning of chitosan solution combined with rice husk liquid smoke as a natural food preservative. The research method used a completely randomized design (CRD) with 5 treatments repeated three times. The treatments used were: A0 (1% Chitosan + 1% Acetic Acid + 1% Glucose), A1 (1% Chitosan + 1% Acetic Acid + 1% Glucose + 1% Rice Husk Liquid Smoke), A2 (1% Chitosan + 1% Acetic Acid + 1% Glucose + 2% Rice Husk Liquid Smoke), A3 (1% Chitosan + 1%s Acetic Acid + 1% Glucose + 4% Rice Husk Liquid Smoke), A4 (1% Chitosan + 1% Acetic Acid + 1% Glucose + 6% Rice Husk Liquid Smoke). The results showed that chitosan combined with rice husk had a very significant effect on the browning index value. The higher the concentration of liquid smoke, the higher the result of the browning index produced. The Maillard reaction occurs due to the presence of aldehyde ketone compounds in the liquid smoke of rice husk meeting the free amino acid compounds of chitosan and glucose in the heating process so that the Maillard reaction can take place. The best concentration is treatment A4 which gets optimal results on the brownish index produced.

Abstract

This research aimed to determine the effective concentration of watermelon rind extract for enhancing koi fish immune system which attacked by Aeromonas hydrophila bacteria. Completely Randomize Design Experiment is used as base research method who has five treatments and three replications. The treatment have been given addition of watermelon rind extract in feed with concentration which are A (0 ppm), B (6.250 ppm), C (7.500 ppm), D (8.250 ppm) and E (9.000 ppm). The observed parameters are clinical symptoms, total leucocyte, survival rate, and water quality. The result of this research indicated that the addition of watermelon rind extract in feed with the amount of concetration between 8.250 until 9.000 ppm could enhancing fish immune system and prevent Aeromonas hydrophila bacteria infection, this could be showed by the enhanced amount of leucocytes are 49,24 and 55,96%, and the highest survival rate shows 84,44% and 71% value respectively.
