A Framework to Measure Water and Energy Footprint at Demand Side Maria Anityasari; Mar’atus Sholihah; Diesta Iva Maftuhah
Indonesian Journal of Life Cycle Assessment and Sustainability Vol. 1 No. 2 (2017)
Publisher : Indonesian Life Cycle Assessment Network (ILCAN)

There is no doubt that water is an essential part of human life. Unfortunately it is often neglected and is not managed well. Flood and drought in many areas in Indonesia are examples of serious deficiency in water management. Urban areas, in particular, have serious threats in water sustainability due to the dramatic increase of population. Regrettably, there is little knowledge on water infrastructure in macro to micro level, people’s attitude toward water, stakeholders’ inter-connectivity in water management, institutional capabilities in managing water management, and appropriate technologies to use water wisely in different settings. At the demand side alone, complexities can be found in water usage infrastructure. A pilot survey found that more than 65% household in Surabaya installed water pump to access clean water. This means that the total environmental impact of water usage has to incorporate energy footprint in the equation, in addition to the water footprint itself. This paper will present a developed framework to portray the tangle between water and energy at the demand side and how to measure its environmental impact. Benefits of its implementation and potential future work will be discussed and outlined.

The Importance of Data Quality in Using LCA Approach as A Decision Supporting Tool: Comprative Case Study between Injection Moulding Machines in Processing Polypropylene Sharah Yunihar Saputra; Jessica Hanafi

Indonesia is developing an awareness of life cycle perspective, where a product cannot only be analysed in a certain phase but shall be analysed throughout its life cycle. In developing this concept, the understanding of data quality in selecting and recording datasets is important. Many LCA practitioners often neglected the importance of understanding different types of datasets and tracking and documenting dataset. The objective of this paper is to understand the effect of technology coverage in data quality of Life cycle assessment (LCA) and the use of LCA approach as a decision supporting tool. A case study comparing two production methods of a product made of polypropylene (PP) is conducted. Injection moulding machines used in these two plants are different in terms of technology aspect. Comparison between injection moulding machines in these plants was conducted and actual data from the production site were gathered. SimaPro 8 by Pre Consultants is used for life cycle assessment of the machines. Two types of methods, i.e. TRACI and ReCipe, are used in impact assessment stage. The result implied that the technology difference shows significant variation of impact related to energy consumption between both plants. Therefore careful consideration must be taken when using and recording datasets to ensure suitability of the datasets for reuse.

Life Cycle Analysis of Carbon Dioxide Emission Utilization in Enhanced Oil Recovery (EOR) Activity Akhmad Hidayatno; Armand Omar Moeis; Achmad Yusaq Faiz Fadin

The focus of this research is to analyze potential environmental impact in the utilization of carbon dioxide (CO2) as miscible gas injection on Enhanced Oil Recovery (EOR) activity. The reinjection of CO2 would reduce the amount of CO2 release in the air and is considered relatively as a new innovative approach. Responsible innovation (RI) is a research framework that considers aspects of sustainability both in terms of social, economic, and environmental toward an innovation made with five dimensions; reflexivity, deliberation, anticipation, responsiveness, and participation. However, RI does not have a specific quantitative approach to support the analysis. Therefore, this research proposes the use of simplified Life Cycle Assessment (LCA) as the quantitative analysis tool to support the RI analysis, using the case study of Subang Gas-Well, West Java, Indonesia. The case study has four main process units of CO2-Enhanced Oil Recovery, from the Well in Subang, CO2 Recovery, CO2 Transmission and the EOR Oil Well in Jatibarang. Based on the calculation, among the various impact categories, the biggest potential environmental impact is the contribution to acidification impact, followed by photo-oxidant formation, climate change and depletion of abiotic resources.

The Case Study of Life Cycle Perspective in Ready-mix Industry Yosephine Dwi Martina Widowati
Indonesian Journal of Life Cycle Assessment and Sustainability Vol. 1 No. 2 (2017)
Publisher : Indonesian Life Cycle Assessment Network (ILCAN)

ASEAN Economic Community (AEC) is a global commitment and has been started since December 2015. Globalization encourages countries to develop their own environment voices as environment has been also a global issue. Infrastructure is one of the key developments. Construction, which is an important part of infrastructure development depends heavily on the concrete industry. Ready-mix concrete is preferred material for construction because it has a good quality, ready to use, and cheaper. The thirty mega construction projects which have to be completed in 2019 will push ready-mix concrete industries to grow fast. This grow will undoubtedly have an impact on the environment.The purpose of this study is to observe the environmental impact of ready-mix concrete industry. This will cover an observation of life cycle perspective implementation, identification of the main potential environmental impacts and risks, identification of control and influence, and identification of the potential improvement opportunities. This study will hopefully contribute to the improvement of environmental awareness and stimulate more exhaustive research or study about environmental impact in Ready-mix concrete industry in the future. The method of this qualitative study is site observation and indirect investigation which included 15 plants at multiple locations. This study also addressed idea(s) around the understanding of life cycle perspective approach as described in the newest version of ISO 14001-2015 and ISO 14004-2016.

Challenges for Life Cycle Assessment Of Palm Oil Production System Heinz Stichnothe; Cécile Bessou
Indonesian Journal of Life Cycle Assessment and Sustainability Vol. 1 No. 2 (2017)
Publisher : Indonesian Life Cycle Assessment Network (ILCAN)

Growing demand for palm oil is driven by increasing human population, income growth as well as biodiesel stimulation programs. Covering an area of over ten million ha in Indonesia, palm oil production is also one of the most important sources of crop residues while processing generates large amounts of wastewater. Cultivation and processing of this crop are considered as potentially large sources of emissions. Improving environmental impacts of the palm oil production can help to reduce existing emissions while increasing yield and generating surplus energy and farm income. However, area expansion for oil palm plantation is perceived as closely linked to illegal logging, deforestation and diminishing biodiversity. Apart from ensuring sustainable land use change, the use of residues is the most important criterion in ensuring sustainable palm oil. It is important to note that there are trade-offs (e.g. between maximizing bio energy production, reducing environmental impacts other than greenhouse gases (GHG), and sustaining soil fertility). Nitrogen (N) losses in palm oil production systems are a major environmental and economic issue. Unfortunately, there is little comprehensive knowledge on how to calculate N-budgets in oil palm plantation in order to optimize fertilization, taking into account N-leaching and N-gaseous emissions. Land use, soil-carbon, N-emissions and biodiversity are key aspects of life cycle assessment (LCA) of palm oil production systems and they pose a number of methodological questions.
