The decrease level of water quality of Brantas Watershed in Malang Raya was observed in this study. The aim of this study was to observe the decrease level of water quality of Brantas Watershed from Batu to Malang City. This study was carried out in the Brantas Watershed of Malang Raya (8 stations: A, B, C, D, E, F, G, and H) for 18,4 Km. The water quality parameters observed in this study were: CODmn (permanganometry), CODcr (CODmn correlation based analysis), dissolved oxygen (DO) (Winkler iodometry), TDS and electrical conductivity (EC) (EC meter), pH (pH meter), and turbidity (Turbidity meter). The result showed the value of CODmn: 1,8-10,2 mg/L, CODcr: 5,6-31,5 mg/L, DO: 4,0-6,1 mg/L, TDS: 204-289 mg/L, EC: 430-617 µS/cm, pH: 7,1-7,6, and turbidity: 2,02-10,30 NTU. There are 3 stations (A, B, and C) with 1st class water quality, 1 station (D) with the 2nd class water quality, and 4 stations (E, F, G, and H) with 3rd class water quality. The decrease of water quality in the Brantas Watershed from Batu to Malang City was up to 3 times with a decrease rate of 2,3 mg/L-1Km-1. The decomposition of organic materials in the water of Batu City and western part of Malang City is relatively better than that of central parts of Malang City which might be caused by the over capacity of recovery (Self-purification mechanism).

 Abstract. Hidayati D, Nurtjahyani SD, Oktafitria D, Ashuri NM, Kurniallah W. 2019. Short Communication: Evaluation of water quality and survival rate of red tilapia (Oreochromis niloticus) by using rice-fish culture system in quarry land of clay. Biodiversitas 20: 589-594. Quarry land is an area that has been used as mining land and has different characteristics from the former conditions before being mined so that the level of productivity of the soil decreases. This study aims to determine the suitability of clay quarry land in Tuban as a cultivation medium based on the analysis of the water quality and survival rate of red tilapia (Oreochromis niloticus) using rice-fish culture system. This study used a completely randomized experimental design method with triplicate of three ratio of cultivation medium using Ex-mining Land Soil (EmLS) from quarry land and Top Soil, i.e., 1:0 (A), 1:1 (B), and 0:1 (C/Control). Results of water quality measurements that include nitrite, nitrate, temperature, pH, and dissolved oxygen in descriptive unreal influence showed good condition. However, ammonia gives a significantly different effect mainly on the survival rate in 30 days nurture. In the end, the ANOVA test result of tilapia survival in treatment A was not significantly different (P>0.05) with treatment B and control. Based on these data, it can be seen that the EmLS from the quarry land of clay and TS can be used as a medium for cultivation of red tilapia (O. niloticus) with the recommended ratio of 1:1.

The Kapar fish  (Belontia hasselti) is the consumption fish that is obtained only on wild caught. Not yet succeeded in culture this fish, so domestication is needed as an early stage of the aquaculture. The purpose of this research was to knowning the stages of domestication of Kapar fish caught from the Sebangau river in the process of adaptation to new habitats in semi-permanent ponds which is seen from the observation of water quality as well as the growth and survival rate of the Kapar fish. Environmental adaptation for culture fish is the key to successful domestication. Observations of water quality in the fish's wild habitat with the quality of the water where the fish adapt in the pond are slightly different, especially the DO and pH values, but the water quality is still within the tolerance of the Kapar fish to live. The water quality parameters show the temperature in the range 27-29 °C, DO in the range 3-4.2 mg.L-1, and pH in the range 7-7.4. The growth in length and weight during the research showed that the fish were able to adapt feeding. The length and an average weight of Kapar fish until the research were 12.1 cm in length and 31.4 g of weight and it was known that during the research period the absolute length growth of Kapar fish was 1 cm and the absolute weight growth was 8 g . Results of data analysis carried out during the research that the survival rate of Kapar fish is 83 %.
