Pemanfaatan air limbah hasil pengolahan (effluent) dari Instalasi Pengolahan Air

Limbah (IPAL) menjadi air penyiram tanaman merupakan upaya inovatif dalam

mendukung prinsip ekonomi sirkular dan keberlanjutan lingkungan. Penelitian ini

dilakukan di PT Anugrah Analisis Sempurna (AAS) yang telah

mengimplementasikan sistem IPAL dan memodifikasi alurnya agar air limbah hasil

olahan dapat dimanfaatkan kembali untuk penyiraman tanaman. Evaluasi dilakukan

terhadap kualitas effluent dan air tanah di sumur pantau dengan mengacu pada baku

mutu teknis No. 660.1/1018.DLHK. Hasil penelitian menunjukkan bahwa sebagian

besar parameter kualitas air (pH, TSS, BOD, COD, Total Coliform, dll.) berada di

bawah ambang batas baku mutu, meskipun sempat ditemukan konsentrasi amoniak

yang melebihi ambang batas pada bulan tertentu. Dengan modifikasi sistem IPAL

melalui penambahan sand filter dan carbon filter, air limbah yang dihasilkan

memenuhi syarat untuk dimanfaatkan sebagai air penyiram tanaman.

ABSTRACT

Utilization of processed wastewater (effluent) from Wastewater Treatment Plants

(WWTP) into water for watering plants is an innovative effort to support the

principles of circular economy and environmental sustainability. This research was

conducted at PT Anugrah Analis Sempurna (AAS) which has implemented the

WWTP system and modified its flow so that the processed wastewater can be

reused for watering plants. Evaluation was carried out on the quality of effluent and

groundwater in monitoring wells by referring to technical quality standards No.

660.1/1018.DLHK. The results of the study showed that most of the water quality

parameters (pH, TSS, BOD, COD, Total Coliform, etc.) were below the quality

standard threshold, although ammonia concentrations were found to exceed the

threshold in certain months. By modifying the WWTP system by adding sand filters

and carbon filters, the wastewater produced meets the requirements to be used as

water for watering plants.
