Abstract
Limbah budidaya tambak udang memiliki karakteristik dimana pH, amonia, fosfor, BOD5 dan TSS lebih tinggi sementara konsentrasi DO lebih rendah dari perairan sekitar. Bahan kontaminan terakumulasi didalam sedimen perairan yang mengakibatkan peningkatan kadar nitrogen, hidrogen sulpida, penipisan oksigen dan meningkatkan populasi bakteri. Salah satu pengolahan limbah secara biologis yang dapat digunakan dalam mereduksi polutan adalah menggunakan biofilter aerob dengan media bioball. Penelitian ini bertujuan untuk mengkaji dan menganalisis efisiensi penyisihan BOD, COD, Ammonia, Nitrat, Phospat, dan peningkatan DO dan pengaruh suhu dalam air limbah budidaya tambak udang setelah melalui reaktor biofilter.
Variasi yang dilakukan adalah tinggi media biofilter serta proses dengan sistem aerasi 48 jam dan aerasi intermitten 12 jam. Tinggi media filter yang digunakan dalam reaktor adalah 30 cm, 40 cm, dan 50 cm. Variasi ini dilakukan agar dapat membandingkan efisiensi dan kinerja dari masing - masing biofilter tersebut.
Setelah dilakukan running reaktor didapatkan hasil untuk analisis pengaruh variasi tinggi dengan sistem aerasi pada running I dan running 2 ini dapat disimpulkan bahwa penyisihan polutan air limbah dimana parameter yang diuji yakni COD, BOD, Amonia, Nitrat, dan DO didapatkan hasil bahwa tidak ada beda dalam perlakuan variasi tinggi media tetapi ada beda pada perlakuan variasi sistem aerasi sementara itu untuk parameter PO43- didapatkan hasil tidak ada beda dalam perlakuan variasi tinggi media maupun sistem aerasi. Untuk parameter yang diuji, limbah budidaya tambak udang sudah memenuhi baku mutu dengan konsentrasi removal tertinggi yang didapat yakni BOD5 15 mg/l, NH3 0,09 mg/l, NO3 0.81 mg/l, sementara itu untuk COD yakni 33.78 mg/l dan peningkatan tertinggi DO 5.5 mg/l. Tetapi untuk parameter PO43- masih melebihi baku mutu air limbah yang akan dibuang ke badan air terdekat yakni Kali Lamong dengan konsentrasi 0.78 mg/l.

The wastes of shrimp pond have characteristics where the pH, ammonia, phosphorus, BOD5 and TSS are higher, while DO concentration is lower than surrounding waters. Contaminants accumulate in aquatic sediments which cause increasing levels of nitrogen, hydrogen sulfide, and oxygen depletion and increasing the population of bacteria. Aerobic bio filter by using bio ball media is one of biological wastewater treatment method which is able to reduce pollutants. This research aims to assess and analyze the removal efficiency of BOD5, COD, Ammonia, Nitrate, Phosphate, and increasing DO effects in shrimp pond waste water going through the biofilter reactor.
This biofilter reactor is designed with varied levels of bioball which are the levels of biofilter media. This reactor is also supported by 48 hours of aeration system and 12 hours of intermittent aeration. High filter media used in the reactor are 30 cm, 40 cm, and 50 cm. These variations are created to compare the efficiency and performance of each aerobic biofilter reactor.
After running the reactor and do the analysis about the effect of levels media variation and aeration system on the first running and the second running of this research, it can be concluded that for tested waste water pollutants parameters including COD, BOD, Ammonia, Nitrate, and Phosphate, it shows no different in media high variation, while there is different in aeration system variation. Meanwhile, for parameter PO43-, the result is that there is no difference for both media high variation and aeration system. For the parameters tested, shrimp pond waste water already met the standard with the highest concentration obtained removal of BOD5 15 mg/l, NH3 0.09 mg/l, NO3 0.81 mg/l, while that for COD that is 33.78 mg/l and DO highest increase is 5.5 mg/l. However, for PO43- parameter, it still exceeds the quality of waste water to be discharged into the outfall with the concentration of the Lamong River showed in 0.78 mg/l.
