Abstract

The liquid waste of the tofu industry around residential area will affect the quality of their well water. This study was aimed to determine the effect of the tofu industry wastewater on wells located around the tofu industry at different distances. This study took 3 well water samples from 3 well sources with a distance of 10 meters from the tofu industry, 20 meters from the tofu industry, and 30 meters from the tofu industry. The well water samples were examined at the Health Laboratory of Sukoharjo Regency to determine the physicochemical properties such as odor, taste, color, temperature, turbidity, and amount of dissolved solids, such as iron, manganese, chloride, hardness as CaCO3, pH, and sulfate, as well as biological contamination such as coliform and feces. From the results of this study, it was found that the quality of well water around the tofu industry located in Madegondo Grogol Sukoharjo Village is only suitable for bathing and washing but is not suitable for consumption in accordance with the quality standards of clean water quality in accordance with the Regulation of the Minister of Health of the Republic of Indonesia Number 32 2017. AbstrakLimbah cair industri tahu yang ada disekitar rumah warga akan mempengaruhi kualitas air sumur warga sekitar. Penelitian ini bertujuan untuk mengetahui pengaruh dari limbah cair industri tahu terhadap sumur yang terletak di sekitar industri tahu tersebut dengan jarak yang berbeda-beda. Penelitian ini mengambil sampel air sumur sejumlah 3 dari 3 sumber sumur dengan jarak 10 meter dari industri tahu, 20 meter dari industri tahu, dan 30 meter dari industri tahu. Sampel air sumur tersebut kami uji di Laboratorium Kesehatan Kabupaten Sukoharjo untuk mengetahui kelayakan fisik seperti bau, rasa, warna, suhu, kekeruhan, dan jumlah zat padat terlarut, kelayakan kimiawi seperti besi, mangan, khlorida, kesadahan sebagai CaCO3, pH, dan sulfat, dan kelayakan bakteriologi seperti coliform dan colitinja. Dari hasil penelitian tersebut didapatkan hasil bahwa kualitas air sumur di sekitar industri tahu yang terletak di Desa Madegondo Grogol Sukoharjo hanya layak digunakan untuk mandi dan mencuci namun tidak layak untuk dikonsumsi sesuai dengan standar baku mutu kualitas air bersih sesuai dengan Peraturan Menteri Kesehatan Republik Indonesia Nomor 32 Tahun 2017.

Abstract

Laundry activities produce liquid waste containing phosphates, surfactants, ammonia, nitrogen, TSS, BOD, and COD. Liquid waste treatment needs to be done so as not to disturb the environment. One method of liquid waste treatment is the electrocoagulation method. This study aims to determine the effect of time and voltage, as well as the effect of plate surface area and current strength on the decrease in BOD, COD, and TSS levels in laundry waste by continuous electrocoagulation method. Sampling was carried out at Basmala Laundry Kartasura. This study used variations in plate surface area (832; 1036; 1240 cm2) and current strength (1; 1.5; 2 amperes) as well as voltage (10; 17; 24 volts) and residence time (1; 2; 3 hours). The results showed a decrease in COD levels at a voltage of 17 volts with a residence time of 2 hours by 104 mg/L and at a plate surface area of 1240 cm2 with a current strength of 2 amperes by 48 mg/L. The decrease in BOD levels at a voltage of 17 volts with a residence time of 1 hour amounted to 64.5 mg/L and a plate surface area of 1240 cm2 with a current strength of 2 amperes amounted to 48 mg/L. The decrease in TSS levels at a voltage of 24 volts with a residence time of 3 hours was 12 mg/L and at a plate surface area of 832 cm2 with a current strength of 1.5 amperes and a plate surface area of 1036 cm2 with a current strength of 2 amperes was 15 mg/L Abstrak Kegiatan industri rumah tangga laundry menghasilkan limbah cair yang mengandung fosfat, surfaktan, amoniak dan nitrogen, TSS, BOD, dan COD. Pengolahan limbah cair perlu dilakukan agar tidak mengganggu lingkungan. Salah satu metode pengolahan limbah cair adalah metode elektrokoagulasi. Penelitian ini bertujuan untuk mengetahui pengaruh waktu dan tegangan, serta pengaruh luas permukaan plat dan kuat arus terhadap penurunan kadar BOD, COD, dan TSS pada limbah laundri dengan metode elektrokoagulasi secara kontinyu. Pengambilan sampel dilakukan di Basmala Laundri yang terletak di Kartasura. Pada penelitian ini menggunakan variasi luas permukaan plat (832; 1036; 1240 cm2) dan kuat arus (1; 1,5; 2 ampere) serta tegangan (10; 17; 24 volt) dan waktu tinggal (1; 2; 3 jam). Hasil penelitian menunjukkan terdapat penurunan kadar COD pada tegangan 17 Volt dengan waktu tinggal 2 jam sebesar 104 mg/L dan pada luas permukaan plat 1240 cm2 dengan kuat arus 2 ampere sebesar 48 mg/L. Penurunan kadar BOD pada tegangan 17 Volt dengan waktu tinggal 1 jam sebesar 64,5 mg/L dan luas permukaan plat 1240 cm2 dengan kuat arus 2 ampere sebesar 48 mg/L. Penurunan kadar TSS pada tegangan 24 Volt dengan waktu tinggal 3 jam sebesar 12 mg/L dan pada luas permukaan plat 832 cm2 dengan kuat arus 1,5 ampere dan luas permukaan plat 1036 cm2 dengan kuat arus 2 ampere sebesar 15 mg/L.
