Abstract

Instalasi Pengolahan Air (IPA) merupakan fasilitas yang berperan dalam menyediakan air bersih bagi masyarakat. Proses pengolahan air di IPA memerlukan konsumsi energi listrik dan bahan kimia yang berpotensi menimbulkan dampak terhadap lingkungan. Oleh karena itu, penelitian ini bertujuan untuk mengidentifikasi faktor utama penyebab dampak lingkungan, menganalisis potensi dampak lingkungan dari proses pengolahan air bersih, serta menyusun skenario rekomendasi pengelolaan lingkungan berdasarkan hasil analisis Life Cycle Assessment (LCA) dan studi literatur pada Instalasi Pengolahan Air (IPA) Ngagel III.
Penelitian ini menggunakan metode Life Cycle Assessment (LCA) dengan batas sistem gate-to-gate yang mencakup proses mulai dari unit intake hingga reservoir. Analisis dilakukan menggunakan perangkat lunak SimaPro dengan database Ecoinvent dan metode CML-IA Baseline karena memiliki cakupan data yang luas dan sesuai untuk analisis dampak lingkungan melalui tahapan Goal and Scope Definition, Life Cycle Inventory (LCI), Life Cycle Impact Assessment (LCIA), dan Interpretation. Selanjutnya, skenario pengelolaan lingkungan akan disusun berdasarkan hasil analisis LCA dan studi literatur.
Hasil penelitian menunjukkan bahwa konsumsi energi listrik pada pompa di unit bak pengumpul merupakan hotspot utama penyebab dampak lingkungan. Dampak dominan yang dihasilkan meliputi marine aquatic ecotoxicity, abiotic depletion (fossil fuels), dan global warming potential (GWP100a) karena sebagian besar listrik yang digunakan dihasilkan dari pembangkit berbahan bakar fosil. Berdasarkan hasil analisis LCA dan studi literatur, dikembangkan dua skenario pengelolaan lingkungan, yaitu skenario efisiensi energi melalui penerapan teknologi Variable Speed Drive (VSD) yang mengurangi konsumsi listrik pompa sebesar 30%, serta skenario pemanfaatan energi surya yang memasok 20% kebutuhan listrik. Hasil simulasi menunjukkan bahwa skenario efisiensi energi memberikan penurunan dampak lingkungan yang lebih besar dibandingkan skenario energi surya sehingga direkomendasikan sebagai prioritas pengelolaan lingkungan untuk mendukung keberlanjutan lingkungan pada operasional IPA Ngagel III.

Water Treatment Plant (WTP) are facilities that play a role in providing clean water to the community. The water treatment process at WTP requires the consumption of electrical energy and chemicals, which have the potential to impact the environment. Therefore, this study aims to identify the main factors causing environmental impacts, analyze the potential environmental impacts of the clean water treatment process, and develop recommended environmental management scenarios based on the results of the Life Cycle Assessment (LCA) analysis and literature review at the Ngagel III Water Treatment Plant (WTP).
This study uses the Life Cycle Assessment (LCA) method with gate-to-gate system boundaries covering processes from the intake unit to the reservoir. The analysis was conducted using SimaPro software with the Ecoinvent database and the CML-IA Baseline method because it has a broad data coverage and is suitable for environmental impact analysis through the stages of Goal and Scope Definition, Life Cycle Inventory (LCI), Life Cycle Impact Assessment (LCIA), and Interpretation. Furthermore, environmental management scenarios will be developed based on the results of the LCA analysis and literature review.
The results of the study indicate that electrical energy consumption in the pump in the collection tank unit is the main hotspot causing environmental impacts. The dominant impacts produced include marine aquatic ecotoxicity, abiotic depletion (fossil fuels), and global warming potential (GWP100a) because most of the electricity used is generated from fossil fuel power plants. Based on the results of the LCA analysis and literature studies, two environmental management scenarios were developed, namely the energy efficiency scenario through the application of Variable Speed Drive (VSD) technology which reduces pump electricity consumption by 30%, and the solar energy utilization scenario which supplies 20% of electricity needs. The simulation results show that the energy efficiency scenario provides a greater reduction in environmental impacts than the solar energy scenario, so it is recommended as an environmental management priority to support environmental sustainability in the operation of the Ngagel III WTP.
