Abstract

This research was conducted in August and November 2013 in the province of Riau Strait Bengkalis. The method used in this study is a survey method . The purpose of this study was to determine the potential catches Terubuk ( Tenualosa macrura ) in Bengkalis waters. The results showed that the results of the survey of the Terubuk fish were caught fishing waters Bengkalis the month from August to November 2013. Retrieved Terubuk number and size of fish caught as many as 3554 head comprising 1082 males and 2472 Terubuk tail tail Terubuk females . Terubuk fish growth speed at the time a young age faster than when the fish is old. The rapid growth of the young - old fish occurs because the energy obtained from food are mostly used for growth. In older fish the energy obtained from food is no longer used for growth, but only used to maintain it self and replace the damaged cells.The rate of death arrest ( F ) during the study period is higher than the rate of natural mortality ( M ) , so that the total mortality rate ( Z ) during the periods of the study are determined by the rate of death arrest ( F ). Terubuk fish mortality rate during the study period due to factors at the time of capture by fishing for migratory fish spawning . Terubuk endangered fish caused by two main factors : first, the seizure at the time of entry into migratory fish Strait Bengkalis, secondly, the quality of the water into a fish alive Terubuk diminishing.Keywords : Potential , Terubuk Fish , Aquatic Bengkalis

Abstract Thebutchery liquid waste is rich in BOD5andCOD  and it need to be processed before being flown to the environment. To understand the effectiveness of combined anaerob-aerob biofilters in reducing the BOD5and COD in the butchery liquid waste , a study was conducted in February -  March 2018. The anaerob tanks were completed with pieces of brick, gravel and sand media (60 cm height), while that of the aerob was completed with coconut fibers and charcoal media (40 cm height). Around 215 L waste was kept in the anaerob tanks for 12 days and then it was flown to the aerob tanks and was kept for 10 days. Samplings for water quality parameters (BOD5, COD, DO and pH) was conducted 2 times, before the waste was processed and by the end of the experiment. The processed waste was then used for rearing Spirulinasp, 100 ml of Spirulina stock (104 cells/ ml) were reared in 1 liter of processed waste. Spirulina density was checked everyday. Results shown that the BOD5 reduced, from 1,307 mg/L to 113 mg/L(the effectiveness was 91.35 %); COD reduced, from 7,430 mg/L to 182 mg/L ( the effectiveness was 97,55 %); DO improved (from 1 mg/L to 5 mg/L) and pH also increased, from 6 to 8. The Spirulina density peaked by the 7th day, it was 4,074,666 cells/ml. Based on data obtained, it can be concluded that the use of anaerob-aerob biofilter was effective in improving the butchery waste water quality. Keywords : Organic waste, Anaerob tanks, Aerob tanks, Spirulina sp.
