Utilization of Air Conditioning (AC) Wastewater Filtration System as Water Supply for Plants

Abstract

Abstrak: Air buangan Air Conditioning (AC) memiliki kuantitas yang cukup banyak, tetapi biasanya air buangan AC langsung dibuang ke lingkungan sekitar melalui pipa saluran air buangan AC. Tujuan penelitian adalah (1) mengetahui debit air buangan AC yang dihasilkan dalam kurun waktu 30 menit dan (2) Mengetahui efektifitas filter dalam mengurangi kandungan pencemar air buangan AC sehingga baik digunakan untuk pengairan tanaman. Penelitian dilakukan dengan menganalisis kuantitas dan kualitas air buangan AC di Gedung CC Universitas Muhammadiyah Jember. Parameter yang dianalisis meliputi kesadahan, pH dan ammonia. Salah satu solusi untuk mensterilkan kandungan air limbah AC dengan menggunakan spons yang mampu menangkap padatan dalam air sebelum air masuk wadah dan arang aktif yang dinilai mampu menurunkan kadar NH₄. Selain menggunakan arang tempurung kelapa, paparan sinar UV yang dirasa dapat mengurangi bakteri yang terkandung dalam air AC tersebut. Sinar UV dapat berfungsi sebagai penghancur bakteri dan mikroorganisme sehingga aman untuk digunakan, baik untuk makhluk hidup maupun lingkungan. Penelitian ini menggunakan jenis penelitian kualitatif bersifat deskriptif dengan pendekatan evaluasi yang bertujuan untuk mengetahui jumlah air buangan AC dalam kurun waktu 30 menit dan mengetahui kualitas fisik dan mikrobiologi air buangan AC dengan menganalisis data dan dibandingkan dengan Permenkes RI No. 32 tahun 2017 tentang Standar Baku Mutu Kesehatan Air Keperluan Sanitasi, Kolam Renang, Solus Per Aqua dan Pemandian Umum. Pengumpulan data dilakukan dengan cara pengukuran debit air buangan AC, observasi, wawancara dan dokumentasi. Instrumentasi yang digunakan berupa gelas ukur, TDS meter, termometer, turbidity meter, timer, botol sampel, bunsen, alkohol dan es box. Berdasarkan hasil pemeriksaan kualitas air buangan AC dengan spesifikasi AC 1 PK didapatkan hasil pemeriksaan parameter fisik dan mikrobiologi yang memenuhi syarat sesuai dengan Permenkes RI No. 32 tahun 2017 tentang Standar Baku Mutu Kesehatan Air Keperluan Sanitasi, Kolam Renang, Solus Per Aqua dan Pemandian Umum

Abstract: Air Conditioning (AC) waste water has quite a lot of quantity, but usually AC waste water is directly discharged into the surrounding environment through AC waste water pipes. The objectives of the study were (1) to determine the discharge of AC waste water produced within 30 minutes and (2) to determine the effectiveness of the filter in reducing the pollutant content of AC waste water so that it is good for plant irrigation. The research was conducted by analyzing the quantity and quality of AC waste water in the CC Building, Muhammadiyah University of Jember. Parameters analyzed include hardness, pH and ammonia. One solution to sterilize AC wastewater is by using a sponge that is able to capture solids in the water before the water enters the container and activated charcoal which is considered to be able to reduce NH4 levels. One of the ingredients for making charcoal comes from coconut shells, which are relatively cheap. In addition to using coconut shell charcoal, exposure to UV rays is felt to reduce the bacteria contained in the AC water. UV light can function as a destroyer of bacteria and microorganisms so it is safe to use, both for living things and the environment. This study uses a descriptive qualitative research with an evaluation approach which aims to determine the amount of air conditioning waste water within 30 minutes and to determine the physical and microbiological quality of AC waste water by analyzing the data and comparing it with the Minister of Health Regulation No. 32 of 2017 concerning Health Quality Standards for Sanitation, Swimming Pools, Solus Per Aqua and Public Baths. Data was collected by measuring the discharge of air conditioning, observation, interviews and documentation. The instrumentation used is a measuring cup, TDS meter, thermometer, turbidity meter, timer, sample bottle, Bunsen, alcohol and ice box. Based on the results of the examination of the quality of the AC wastewater with specifications of AC 1 PK, the results of the examination of physical and microbiological parameters that meet the requirements in accordance with the Minister of Health of the Republic of Indonesia No. 32 of 2017 concerning Health Quality Standards for Sanitation, Swimming Pools, Solus Per Aqua and Public Baths.
