Detergent waste can change the color of the water to brown and emit a foul odor. Therefore, it is necessary to make an effort to reduce the amount of pollutants in the detergent waste before it is distributed to the community. The purpose of this study was to prove that the use of zeolite can reduce the sulfur component in soapy water, and to determine the ratio of mixing time and optimum weight of zeolite to achieve maximum Journal of Chemical Process Engineering e-ISSN Number 2655 2967 125 absorption. This research was conducted in a research laboratory majoring in Chemical Engineering, FTI UMI Indonesia, and testing was carried out at SMAK Makassar. This research was conducted using samples of laundry waste, materials such as zeolite, activated carbon and analysis using a spectrophotometer. The research process was carried out by taking 250 ml of waste samples then added with zeoil according to the variables used and the adsorption process was carried out. After that, it was analyzed using a spectrophotometer. From the results of the research conducted, it can be concluded that the use of zeolite can reduce the sulfur component in the laundry waste soap water and optimal absorption occurs in the addition of 40 g of zeolite with a stirring time of 210 minutes. PENDAHULUAN Indonesia merupakan negara kepulauan terbesar di dunia, memiliki perairan yang sangat luas namun cukup tercemar, yang diakibatkan dengan pembuangan limbah yang berasal dari Industri-Industri yang berada di Indonesia, maupun kegiatan rumah tangga tiap harinya. Secara umum limbah diterjemahkan adalah sisa proses produksi, atau juga dapat diterjemahkan sebagai bahan yang tidak mempunyai nilai atau tidak berharga. Atau juga dapat diterjemahkan sebagai barang yang rusak atau cacat dalam proses produksi. Limbah buangan dari industri yang berada di Indonesia lebih banyak dicemari oleh limbah cair yang dibuang ke saluran perairan, kali ataupun selokan. Contohnya sisa pewarna pakaian, pengawet cair, kebocoran minyak di laut yang biasanya akan langsung diolah oleh pusat K3 dalam perusahaan tersebut. Sedangkan, limbah buangan dari kegiatan rumah tangga seperti bekas cucian piring maupun pakaian yang lebih banyak mengandung detergen. Limbah detergen termasuk ke dalam jenis greywater yang mengandung bahan-bahan berbahaya seperti petrokimia dan sulfur bahkan nonylphenol ethoxylates (NPE) yang merupakan produk sampingan dalam detergen dan salah satu ancaman utama bagi kehidupan laut dengan meniru hormone dan mengganggu sistem endoktrin. Alhasil, detergen yang dibuang dalam tangka bisa membunuh bakteri pengurai. Begitu pula jika dibuang langsung ke selokan, akan bermuara ke sungai dan membuatnya tercemar. Jika kita amati saat ini perubahan aktifitas manusia telah mengalami gradasi yang sangat signifikan, dimana laju pertumbuhan teknologi dan industri menyebabkan manusia memilih jalan instant dalam","PeriodicalId":15308,"journal":{"name":"Journal of Chemical Engineering & Process Technology","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81979628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PENDAHULUAN Kebutuhan manusia akan pakaian yang bersih dan wangi untuk menunjang aktifitasya yang padat membuat industri laundry berkembang dengan pesat untuk memenuhi kebutuhan tersbut. Industri laundry merupakan salah satu peluang bisnis yang menjanjikan dalam menunjang kesejateraan perekonomian masyarakat karena Proses kerja industri laundry ini sangat sederhana yaitu mencampurkan air dengan detergen. Umumnya detergen tersusun atas tiga komponen yaitu, surfaktan (sebagai bahan dasar detergen)sebesar 20-30%, builders (senyawa fosfat) sebesar 70-80 %, dan bahan aditif (pemutih dan pewangi) yang relative sedikit yaitu 2-8%. Surface Active Agent (surfaktan) pada detergen digunakan untuk proses pembasahan dan pengikat kotoran, sehingga sifat dari detergen dapat berbeda tergantung jenis surfaktannya [8]. Tabel.1. kandungan limbah laundry Sumber. [3] Masalah mulai muncul ketika air limbah dari industri laundry ini ternyata mengandung fosfat yang tinggi berdasarkan tabel 1. yang berasal dari Dodecyl Benzene Sulfonate (DBS) dan senyawa polyphosphate yang merupakan bahan dalam deterjen yang dapat menurunkan kualitas air dan mengganggu proses pelarutan oksigen kedalam badan air serta terjadinya kesuburan yang berlebih (eutrofikasi) di perairan. Oleh karena itu limbah cair dari Industri Laundry ini harus dikelola dengan baik sebelum di alirkan ke saluran air warga. Salah satu cara untuk mengurangi kandungan DBS dan fosfat yaitu dengan proses adsorbsi menggunakan karbon aktif.
