Abstract

This study examines the quality of drainage water at the Central Processing Plant (CPP) Gundih, a natural gas processing facility owned by PT. Pertamina EP Asset 4 Cepu Field. Wastewater generated from gas processing activities and office operations is discharged through northern and southern sewer systems before being released into the environment. The research was conducted over 3 months with weekly sampling to test 5 water quality parameters including pH, temperature, Total Suspended Solids (TSS), Total Dissolved Solids (TDS), and Chemical Oxygen Demand (COD). Results show that temperature parameters met wastewater quality standards (BMAL) with a maximum value of 31.5°C, still below the 40°C standard. pH parameters fluctuated with several values outside the 6-9 standard range, especially in the northern sewer reaching 2.5 and 9.39. TSS and TDS mostly met oil industry waste standards, but some measurements exceeded domestic waste quality standards. COD showed high values exceeding standards, with the highest values reaching 2170 mg/L in the southern sewer and 1080 mg/L in the northern sewer. This study recommends implementing additional treatment systems for COD parameters and strict monitoring of pH fluctuations to ensure wastewater quality complies with environmental regulations.

Abstract

Micellar water merupakan pembersih wajah berbasis air yang mampu mengangkat minyak, kotoran, dan makeup tanpa perlu dibilas. Penelitian ini bertujuan mengembangkan formulasi micellar water dengan bahan aktif alami berupa ekstrak Aloe vera dan vitamin E sesuai preferensi pelanggan. Pengembangan dilakukan melalui analisis kebutuhan pasar, tahap formulasi, serta pengujian kualitas produk. Sebanyak 41 responden dari berbagai profesi dilibatkan untuk menentukan karakteristik produk yang diinginkan. Formulasi mengandung ekstrak Aloe vera 10%, PEG-7 glyceryl cocoate 0,4%, gliserin 1%, propilen glikol 1%, natrium glukoat 2%, asam laktat 3%, dan vitamin E 0,05% dengan akuades sebagai pelarut utama. Ekstrak Aloe vera diperoleh melalui metode maserasi menggunakan etanol 70% sehingga menghasilkan bahan aktif yang stabil. Hasil pengujian menunjukkan pH rata-rata 5,9 yang aman bagi kulit, serta produk efektif, stabil, dan sesuai kebutuhan pasar.
