Air limbah domestik menjadi permasalahan lingkungan yang signifikan di berbagai sektor,

termasuk di sektor perhotelan. Hotel X merupakan hotel dengan tipe bisnis berbintang 4. Instalasi

Pengolahan Air Limbah (IPAL) di Hotel X menggunakan jenis IPAL Sewage Treatment Plant (STP)

yang hanya bersumber dari limbah kamar mandi, dan hasil pengolahan limbah tidak akan dibuang

ke sungai melainkan akan digunakan kembali untuk Flushing toilet dan mengairi tanaman.

Penelitian ini menunjukan bahwa pengolahan air limbah di Hotel X tidak efisien, dengan nilai

efisiensi untuk parameter di bulan Juli 2023 untuk pH memiliki nilai 2%, BOD memiliki nilai

28,86%, COD memiliki nilai 26,6%, TSS memiliki nilai 13,30%, Klorida memiliki nilai 5,38%. Bulan

Agustus 2023 efisiensi paramter pH memiliki nilai 2%, BOD memiliki nilai 24,39%, COD memiliki

nilai 48,30%, TSS memiliki nilai 8,51%, Klorida memiliki nilai 5,38%. Pengujian di uji

menggunakan standar baku mutu Peraturan Pemerintah Nomor 22 Tahun 2021 kelas 4 untuk

Flushing Toilet dan mengairi tanaman.

ABSTRAK

Domestic wastewater has become a significant environmental issue across various sectors,

including the hotel industry. Hotel X is a 4-star business hotel. The wastewater treatment plant

(WWTP) at Hotel X uses a Sewage Treatment Plant (STP) system that only processes wastewater

from bathrooms, and the treated wastewater is not discharged into rivers but is reused for toilet

flushing and irrigation. This study shows that the wastewater treatment at Hotel X is inefficient,

with the efficiency rates for July 2023 parameters as follows: pH at 2%, BOD at 28.86%, COD at

26.6%, TSS at 13.30%, and Chloride at 5.38%. In August 2023, the efficiency rates were as

follows: pH at 2%, BOD at 24.39%, COD at 48.30%, TSS at 8.51%, and Chloride at 5.38%. The

tests were conducted based on the Class 4 quality standards from Government Regulation No.

22 of 2021, for use in toilet flushing and irrigation.
