THE EFFECTIVENESS OF WASTEWATER TREATMENT PLANT IN AL-AKBAR MOSQUE OF SURABAYA

Abstract

Abstract.Indonesia is the largest Muslim country in the world. According to The Royal Islamic
Strategic Studies Center (RISCC), the number of Muslim in Indonesia is around 237.56 million people
or 86.7% of the total population. The need for clean water used in ablution continues to increase
and there are not many ablution water treatment systems. This research aimed to know the
effectiveness of WWTP in Al-Akbar Mosque of Surabaya. The type of this research is descriptive. The
variables studied were the quantity of clean water, the quality of the wastewater, and the
equipment and facility used in the WWTP process. The research sample was 10 samples. Data
analysis was carried out in a qualitative and quantitative descriptive manner according to the
Minister of Environment and Forestry Regulation No. 68 of 2016. In the WWTP in Al-Akbar Mosque
of Surabaya, there is a pre-treatment process with a collector tub and primary treatment by zeolite
multiform filtration. The result of laboratory test of wastewater effluent quality with Ammonia
parameter, Total Coliform and TSS exceeded the quality standard on Monday and Friday, meanwhile
BOD parameter in all samples exceeded the quality standard. The conclusion of this research is the
WWTP is not yet effective in reducing the parameters of Ammonia, Total Coliform, BOD, and TSS on
Monday and Friday because there are no biological and disinfection stages. Suggestion for Surabaya
Al-Akbar Mosque to monitor and evaluate the quality of wastewater and the performance of the
WWTP so that the wastewater can be reprocessed.
