Teknologi Pompa Dosing pada Pengolahan Grey Water di PT Pertamina Lubricants Production Unit Jakarta

Abstract

Pengolahan grey water yang dilakukan perusahaan secara manual belum efektif karena tidak konsisten dalam pemberian dosis klorin dan NaOH, serta tidak efisien terhadap tenaga kerja. Teknologi pompa dosing untuk pengolahan grey water di PT Pertamina Lubricants Production Unit Jakarta berfungsi mengatasi permasalahan tersebut. Penelitian ini untuk mengidentifikasi kelebihan pompa dosing pada pengolahan grey water, menentukan perhitungan stroke pada pompa dosing, serta pengaruh klorin dan NaOH terhadap hasil pengolahan grey water. Metode yang digunakan yaitu deskriptif kuantitatif, dimana hasil yang diperoleh kemudian dijadikan alat menganalisis dan digambarkan secara objektif. Kelebihan penggunaan pompa dosing pada pengolahan grey water yaitu dalam pemberian dosis klorin dan NaOH secara akurat dan juga efisien terhadap tenaga kerja. Pompa ini digunakan untuk menginjeksikan klorin dan NaOH sesuai dosis dan pengaturan strokenya. Dosis satu, klorin SR 40% SL 9,5% dan NaOH SR 40% SL 7,8%, sedangkan dosis dua, yaitu klorin SR 50% SL 9,5% dan NaOH SR 40% SL 11,9%. Hasil pengujian ini diperoleh dosis dua hasilnya lebih baik dan berada di bawah baku mutu sehingga dapat dinyatakan bahwa hasilnya lebih baik dibandinkang dosis satu.

The company's manual processing of grey water has not been effective due to inconsistent dosing of chlorine and NaOH, as well as being inefficient in terms of labor. The dosing pump technology for grey water treatment at PT Pertamina Lubricants Production Unit Jakarta serves to address that issue. This research aims to identify the advantages of dosing pumps in grey water treatment, determine the stroke calculations for dosing pumps, and analyze the effects of chlorine and NaOH on the results of grey water treatment. The method used is quantitative descriptive, where the results obtained are then used as a tool for analysis and are depicted objectively. The advantages of using dosing pumps in grey water treatment include the accurate administration of chlorine and NaOH, as well as efficiency in labor. This pump is used to inject chlorine and NaOH according to the dosage and stroke settings. Dose one consists of chlorine SR 40% SL 9.5% and NaOH SR 40% SL 7.8%, while dose two consists of chlorine SR 50% SL 9.5% and NaOH SR 40% SL 11.9%. The results of this testing show that dose two performed better and is below the quality standard, indicating that its results are superior compared to dose one.
