Hotels produce wastewater as much as 80% of the total use of clean water, the wastewater is categorized as domestic wastewater. Hotel X is a 4-star hotel with a need for clean water of 64,396 m3/day and the waste water produced is 49.33 m3/day. Based on observations and evaluations, it was concluded that Hotel X's wastewater was treated at the WWTP with performance that was still not optimal. So that the method used in this research is descriptively analyzing primary and secondary data, then proceed with evaluation and redesign of certain WWTP units based on existing conditions in the field. Laboratory test results show that the parameters that do not meet the quality standards are TSS 136 mg/L, BOD5 56 mg/L, and COD 174 mg/L, so the units that need to be evaluated based on existing conditions consists of grit chamber units, equalizing tanks, anaerobic tank, aerobic tanks, sludge tanks and sedimentation tanks. Based on the results of the evaluation on the existing WWTP unit at Hotel X, there are WWTP units that need to be optimized, namely equalizing tanks and aerobic tanks, where the detention time exceeds the design criteria. Redesign of dimensional changes to the equalizing tank and aerobic tank units. Based on the calculation results, the detention time in the equalizing tank was 8.5 hours and in the aerobic tank 14.38 hours. The equalizing tank unit has been modified to a depth of 2 m to reduce detention time in the initial processing to 6.8 hours, while for the aerobic tank 2 unit, it is modified to a width of 2.5 m and a length of 2.5 m, the length and width of the aerobic tank unit 2 is equated with the size of tube 1 to reduce detention time in processing to 7.6 hours.

Air limbah domestik merupakan air buangan yang berasal dari aktivitas sehari-hari manusia yang berkaitan dengan pemakaian air seperti mencuci dan mandi yang menghasilkan grey water. Grey water menyebabkan terjadinya pencemaran yang menimbulkan kerugian apabila dibuang kelingkungan. Salah satu teknologi untuk pengolahan grey water pada air limbah domestik adalah constructed wetlands. Biochar dan aerasi dinilai mampu menghasilkan efektivitasdalam penyisihan polutan pada air limbah domestik. Pada penelitian ini air limbah akan dilakukan pengolahan dengan sistem constructed wetland dengan penggunaan biochar dan aerasi. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan biochar dan aerasi dalam menurunan parameter pH, BOD 5 dan amonia pada air limbah domestik pada constructed wetland. Pada penelitian menggunakan variasi waktu aerasi 1 jam : 2 jam dan 1 jam : 4 jam dengan komposisi media tanam biochar 1:1, 1:2 dan 1:3. Konsentrasi awal air limbah domestik BOD 5 yaitu 4041,64 mg/l, Amonia 104,84 mg/l dan pH 8,70. Penggunaan biochar dan aerasi untuk pengolahan limbah domestik pada constructed wetland dinilai efektif dalam menurunkan parameter pH, BOD 5 dam amonia. Penurunan BOD 5 berada rentang hasil uji akhir 172,23 mg/l-17,58 mg/l dan amonia 91,04 mg/l serta netralisasi pH 7,60-7,17. Variasi waktu aerasi dan komposisi media tanam memberikan pengaruh yang cukup signifikan dalam menurukan konsentrasi BOD 5 dan amonia serta dalam menetralkan pH. Penyisihan terbaik terjadi pada variasi media tanam biochar : tanah 1:3 dengan waktu aerasi 1 jam : 4 jam dengan efisiensi untuk parameter BOD 5 99,57% dan amonia 77,26 % sementara netralisasi pH juga terjadi pada variasi yang sama dengan nilai pH 7,17. Penambahan aerasi dan biochar yang berlebih ternyata kurang efektif dalam penyisihan parameter di reaktor constructed wetland karena dapat mengganggu proses degradasi bahan organik secara anaerob.Keywords: Aerasi, Air limbah domestik, Amonia, Biochar, BOD 5, sistem constructed wetland
