Abstract

Indonesia berkomitmen menurunkan emisi gas rumah kaca (GRK) melalui Nationally Determined Contribution (NDC) dengan target pengurangan emisi hingga 43,20% pada tahun 2030. Peningkatan emisi, terutama CO₂ dari aktivitas industri, mendorong terjadinya pemanasan global dan perubahan iklim. Salah satu sektor yang turut berkontribusi adalah industri air, termasuk instalasi pengolahan air (IPA). Oleh karena itu, pengelolaan emisi pada IPA menjadi langkah penting dalam mendukung upaya pengurangan emisi. IPA Legundi milik Perumda Giri Tirta di Kecamatan Driyorejo, Kabupaten Gresik, dengan debit pengolahan 318 liter/detik, berpotensi menghasilkan emisi dari aktivitas operasionalnya, namun analisis carbon footprint pada instalasi ini belum pernah dilakukan.Penelitian ini bertujuan mengidentifikasi sumber emisi, menghitung dan menganalisis carbon footprint, serta merumuskan rekomendasi teknis dan operasional untuk menurunkan emisi karbon dan meningkatkan efisiensi energi pada IPA. Perhitungan carbon footprint dilakukan secara manual menggunakan panduan GHG Protocol dan IPCC Guidelines 2019 Refinement dengan pendekatan Tier 2 untuk faktor emisi. Analisis didasarkan pada data aktivitas yang meliputi penggunaan listrik, produksi bahan kimia, dan transportasi bahan kimia. Penggunaan listrik mencakup operasional pompa dan blower, sedangkan emisi bahan kimia meliputi reaksi kimia, proses produksi, dan transportasi.Berdasarkan Hasil penelitian menunjukkan carbon footprint sebesar 1,08 kgCO₂/m³, yang mencakup Scope 1, Scope 2, dan Scope 3, dengan kontribusi terbesar berasal dari penggunaan bahan kimia (62,5%) dan energi listrik (37,5%). Besarnya emisi dipengaruhi oleh debit pengolahan, kapasitas pompa, dan kebutuhan bahan kimia. Rekomendasi optimasi dosis koagulan melalui implementasi Streaming Current Monitor (SCM) yang terintegrasi dengan Supervisory Control and Data Acquisition (SCADA) berpotensi menurunkan carbon footprint sebesar 15% dari total emisi yang dihasilkan.

Indonesia is committed to reducing greenhouse gas (GHG) emissions through its Nationally Determined Contribution (NDC), which targets an emission reduction of up to 43.20% by 2030. Increasing greenhouse gas emissions, particularly carbon dioxide (CO₂) emissions from industrial activities, contribute to global warming and climate change. The water sector, including drinking water treatment plants (DWTPs), also contributes to greenhouse gas emissions. Therefore, emission management in DWTPs is an important measure to support national emission reduction efforts. The Legundi Drinking Water Treatment Plant (DWTP), operated by Perumda Giri Tirta in Driyorejo District, Gresik Regency, with a treatment capacity of 318 L/s, has the potential to generate emissions from its operational activities. However, a carbon footprint assessment has not previously been conducted at this facility.This study aims to identify emission sources, calculate and analyze the carbon footprint, and formulate technical and operational recommendations to reduce carbon emissions and improve energy efficiency at the drinking water treatment plant. The carbon footprint was calculated manually based on the GHG Protocol and the 2019 Refinement to the IPCC Guidelines, using the Tier 2 approach for emission factors. The analysis was conducted using activity data covering electricity consumption, chemical production, and chemical transportation. Electricity-related emissions included the operation of pumps and blowers, while chemical-related emissions comprised chemical reactions, chemical production, and chemical transportation.The results showed that the carbon footprint was 1.08 kgCO₂/m³, consisting of Scope 1, Scope 2, and Scope 3 emissions. The largest contribution originated from chemical use (62.5%), followed by electricity consumption (37.5%). Carbon emissions were influenced by operational factors, including treatment flow rate, pump capacity, and chemical demand. The proposed optimization of coagulant dosing through the implementation of a Streaming Current Monitor (SCM) integrated with a Supervisory Control and Data Acquisition (SCADA) system has the potential to reduce the carbon footprint by 15% of the total emissions generated.
