Abstract

PT. X’s activities, such as the consumption of clean water by workers, visitors, and building maintenance produce domestic liquid waste in the form of grey water. Domestic liquid waste originating form PT. X is used for watering the company’s green open space, that has an area of 2384,4 . The water treatment used is anaerobic and aerobic biofilter. The volume of liquid waste grey water is 70 of the liquid waste produced at 4,09/day, sp the water utilization effieciency is 70. The resulting domestic liquid waste contains the pollutant parameters BOD5, COD, TSS, -N, oil grease, and Total Coliform, so processing by WWTP is required to be below quality standards. The processing units used consist of an interceptor tank, equalization tank, initial settling tank, anaerobic, aerobic, sedimentation, and efflluent tank. After processing and fulfil the quality standards, which has been set, the resulting efflulent is used for at a dose of 0,002 m3/m2/day with a watering frequency of 2 times a day.

Abstract

PT. X merupakan suatu industri yang menghasilkan limbah gas dalam kegiatan operasionalnya. Limbah gas yang dihasilkan PT. X mempengaruhi kualitas udara ambien area PT. X. Kualitas udara ambien perlu diketahui agar dapat disesuaikan dengan baku mutu. Pengujian kualitas udara ambien dilakukan agar parameter pencemar yang terkandung dapat diketahui. Pengujian dilakukan dengan menggunakan sampel dari tiga area di PT. X, antara lain area depan main office, area depan gudang sparepart, dan area depan office powder. Penelitian ini bertujuan untuk mengethaui hubungan kualitas udara ambien antar ketiga area dengan menggunakan perangkat lunak SPSS 23 untuk mengolah dan menganalisis data. Dari analisis yang dilakukan, dapat diketahui bahwa hubungan antara kualitas udara ambien area depan main offcie dan area depan gudang sparepart dengan area depan office powder memiliki korelasi yang kuat dan regresi yang saling mempengaruhi.
