Goal And Scope

Penggunaan  polimer, koagulan, alum, dan gas klorin pada proses penjernihan air akan mengakibatkan dampak lingkungan. Pendekatan yang dapat digunakan untuk mengidentifikasi dan menganalisa dampak lingkungan adalah dengan metode Life Cycle Assessment (LCA). LCA  terdiri dari empat tahapan utama, yaitu goal and scope, Life Cycle Inventory (LCI), Life Cycle Impact Assessment (LCIA), dan Interpretation. Berdasarkan proses software SimaPro 7 metode Impact 2002+, bagian dalam proses pengolahan air yang menimbulkan dampak lingkungan paling besar adalah penggunaan natural gas. Penggunaan natural gas atau listrik per 1 kg air menyebabkan dampak lingkungan non-renewable energy sebesar 5,55E-9 Pt dan pemanasan global sebesar 4,66E-9 Pt. Penggunaan natural gas yang menyebabkan dampak non-renewable energy adalah ketersediaan gas (6E-9 Pt), minyak (7,66E-10 Pt), dan uranium (3,52E-10 Pt) pada tanah semakin berkurang. Penggunaan natural gas yang menyebabkan dampak pemanasan global adalah carbon dioxide hasil pembakaran bahan bakar fosil (5,46E-9 Pt). Besarnya penggunaan listrik pada proses pengolahan air bersih di IPAM disebabkan jarak pengambilan air cukup jauh dan peralatan yang sudah tua.Kata kunci: air, Instalasi Pengolahan Air Minum, Life Cycle Assessment

Goal And Scope

Life Cycle Assessment (LCA) adalah salah satu cara yang dapat digunakan untuk mengevaluasi sistem pengelolaan sampah berdasarkan nilai potensi dampak yang dihasilkan. Bank Sampah Asoka Berseri di Kabupaten Tuban merupakan salah satu contoh unit pengolah sampah yang bertujuan untuk mengurangi potensi dampak dari timbulan sampah secara kualitas maupun kuantitas di wilayah pedesaan. Tujuan studi ini adalah menghitung dan mengevaluasi potensi dampak lingkungan yang dihasilkan dari program bank sampah, kemudian dibandingkan dengan penanganan sampah konvensional yang dilakukan oleh masyarakat. Metode yang digunakan berdasarkan CML Baseline v4.4 dan 14000 standar ISO, meliputi goal and scope, life cycle inventory (LCI), life cycle impact assessment (LCIA) dan interpretasi. Simulasi LCA dilakukan dengan Software OpenLCA untuk menghitung nilai potensi dampak dari setiap kilogram sampah yang dihasilkan. Berdasarkan hasil simulasi, setiap 1 kg sampah yang dikelola oleh bank sampah menghasilkan potensi dampak pemanasan global lebih rendah (6,395 kg CO2 eq.) dibandingkan dengan penimbunan (13,057 kg CO2 eq.) dan pembakaran (10,850 kg CO2 eq.). Pengolahan sampah lebih lanjut menjadi RDF dan kompos di bank sampah berpotensi menghasilkan dampak lingkungan lebih rendah dan menambah pendapatan masyarakat.

Purpose India is a developing economy along with an increasing population estimated to be the largest populated country in about seven years. Simultaneously, its power consumption is projected to increase more than double by 2020. Currently, the dependence on coal is relatively high, making it the largest global greenhouse gas emitting sector which is a matter of great concern. The purpose of this paper is to evaluate the environmental impacts of the natural gas electricity generation in India and propose a model using a life cycle assessment (LCA) approach. Design/methodology/approach LCA is used as a tool to evaluate the environmental impact of the natural gas combined cycle (NGCC) power plant, as it adopts a holistic approach towards the whole process. The LCA methodology used in this study follows the ISO 14040 and 14044 standards (ISO 14040: 2009; ISO 14044: 2009). A questionnaire was designed for data collection and validated by expert review primary data for the annual environmental emission was collected by personally visiting the power plant. The study follows a cradle to gate assessment using the CML (2001) methodology. Findings The analysis reveals that the main impacts were during the process of combustion. The Global warming potential is approximately 0.50 kg CO2 equivalents per kWh of electricity generation from this gas-based power plant. These results can be used by stakeholders, experts and members who are authorised to probe positive initiative for the reduction of environmental impacts from the power generation sector. Practical implications Considering the pace of growth of economic development of India, it is the need of the hour to emphasise on the patterns of sustainable energy generation which is an important subject to be addressed considering India’s ratification to the Paris Climate Change Agreement. This paper analyzes the environmental impacts of gas-based electricity generation. Originality/value Presenting this case study is an opportunity to get a glimpse of the challenges associated with gas-based electricity generation in India. It gives a direction and helps us to better understand the right spot which require efforts for the improvement of sustainable energy generation processes, by taking appropriate measures for emission reduction. This paper also proposes a model for gas-based electricity generation in India. It has been developed following an LCA approach. As far as we aware, this is the first study which proposes an LCA model for gas-based electricity generation in India. The model is developed in line with the LCA methodology and focusses on the impact categories specific for gas-based electricity generation.
