The Wastewater Treatment Plant (WWTP/IPAL) Program for Small and Medium Industries (SMEs) was implemented at the partner
company, PD Alam Aneka Aroma, to address the existing WWTP, which at the time had a treatment capacity of 20 m³/day and was
not yet able to optimally treat approximately 50 m³/day of wastewater generated. To resolve this issue, several program stages were carried
out, including site surveys, preparation of a detailed engineering design (DED) for a WWTP in accordance with the actual wastewater
capacity, construction of the WWTP, trial operation and operational setting of the installed WWTP, training for the person in charge and
WWTP operators, monitoring of WWTP operations, as well as processing of the Technical Approval and the Certificate of Proper
Operation (SLO) for the WWTP. All activities successfully produced the targeted outputs, including wastewater and river water quality
test results, DED documents, WWTP operator training modules, increased human resource capacity through WWTP operational training,
and competency certificates for the person in charge and WWTP operators. PD Alam Aneka Aroma has obtained appropriate technology
in the form of a WWTP, operational knowledge of WWTP management, and a Certificate of Proper Operation (SLO) as evidence of
compliance with environmental regulations, as well as enhanced capacity of WWTP managers/persons in charge and operators, indicated
by professional certification issued by the National Professional Certification Agency (BNSP).

Pertumbuhan jumlah penduduk Indonesia yang terus meningkat diiringi dengan intensifikasi berbagai aktivitas industri, domestik, dan ekonomi yang turut memberikan tekanan signifikan terhadap kualitas lingkungan, khususnya ekosistem sungai. Dalam dua dekade terakhir, berbagai laporan menunjukkan bahwa Sungai di Indonesia mengalami penurunan kualitas yang drastis (UNEP, 2020). Peningkatan beban pencemar, perubahan tata guna lahan, serta rendahnya kesadaran pengelolaan limbah menjadi faktor utama yang memperburuk kondisi ini. Vörösmarty et al. (2010) menyebutkan bahwa tekanan terhadap sumber daya air tawar global meningkat tajam akibat aktivitas manusia, termasuk di negara berkembang seperti Indonesia. Sebagai upaya menjaga kelestarian sumber daya air, pemerintah Indonesia menetapkan berbagai instrumen regulasi untuk mengatur kualitas air dan pengelolaan limbah. Salah satunya adalah Peraturan Pemerintah Republik Indonesia No. 22 Tahun 2021 Lampiran VI tentang baku mutu air sungai nasional, yang menjadi dasar penilaian kualitas badan air. Regulasi ini mempertegas kewajiban seluruh pihak dalam mengendalikan pencemaran air. Selain itu, pemerintah juga menetapkan Permen LH No. 68 Tahun 2016 tentang baku mutu air limbah domestik dan Permen LH No. 5 Tahun 2014 tentang baku mutu air limbah industri. Regulasi ini dirancang untuk memastikan bahwa limbah yang dihasilkan oleh kegiatan domestik maupun industri tidak melebihi ambang batas aman bagi lingkungan (ADB, 2022).
