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.

Indonesia introduced new policies, like PROPER, that require companies to develop LCA capacity. Currently, LCA expertise is still developing. Therefore, the question arises how the development of LCA expertise and a growth of LCA Practitioners can be achieved. In this article learnings and key success factors from global best practices are identified and illustrated based on case studies. The key success factors are 1) harmonization and guidance, 2) capacity building, 3) focus on business value and 4) ease of use. These Key Success Factors can give Indonesia and its LCA practitioners a head start in implementing and embedding LCA in policy implementation and compliance by private companies. Developing a program that provides the following six elements a) Introduction to LCA training, b) Training for managers and policy makers, c) Learning by doing with screening LCAs, d) Facilitate easy to use tools, e) Develop Product Category Rules (PCR) and f) Create a label or other verified report/certificate can accelerate the development of LCA expertise and the implementation of LCA practices.

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.

Analysis of a design process is very important in controlling the initial costs and future costs in possession of an investment project. Therefore, it should be wise to perform a LCC analysis to determine the cost of any category contained in a building project. The analysis also provide information to see how much the total cost incurred by a development project from initial to the future cost by implementing BS ISO 15686 part 5: 2008. The purpose of this study is to identify the cost proportion and make long-term plans of a university building in term of life cycle costing in the area of Univeristy of Atma Jaya Yogyakarta (UAJY). Results of the study show that there are three groups that make up the LCC: the cost of development of the building, the operating costs, and the cost of maintenance and replacement. For a long-term plan the LCC for 25 years the percentage obtained as follows, initial development cost of Rp. 10,301,450,000 (43%), operational costs Rp. 11,085,000,000 (46%), maintenance and replacement costs Rp. 2.660.570.080 (11%).

The manufacturing industry and its relationship with sustainable development simply cannot be separated. Especially, when the government started to show their attention by giving various obligations for the manufacturing industry to implement sustainable development principles, such as the obligation of the company to conduct a social and environmental responsibility by making sustainability report, the environmental impact assessment (AMDAL) report, to participate in various sustainability programs such as Corporate Performance Rating Program (PROPER) and Green Industry Award. There are so many indicators and data that need to be collected in order to fulfill these obligations. It certainly may charge the company in terms of time, yet the number of indicators and the data required were similar between one report to another. There is still no particular design to be able to resolve the issue. Therefore, the aim of this study is to design an integrated data management system for sustainability reporting needs and sustainability programs which has the end result of an application prototype of a system that can help companies, especially in the manufacturing industry to create reporting even more efficient. Data management is done by combining all four types of reporting and program which are Global Report Initiative sustainability report, the AMDAL report, Green Industry program, and PROPER. The prototype is made based on the results of data management using Microsoft Access to store data and to produce four types of summary reports. In the end of the study, it can be concluded that, overall, the system can be implemented and by the withdrawal of three respondents review, the system can improve the efficiency of the company in preparing sustainability reporting. In the evaluation phase, it is found a related method that can be used as the basis to do before making reporting in order to make them more easily 40.98%, that is Life Cycle Assessment.

Publisher : Indonesian Life Cycle Assessment Network (ILCAN)

Sri Lanka has been renowned for its top quality natural rubber products. Among the locally manufactured raw rubber types, ribbed smoked sheets (RSS) hold a significant position as it entails ca. 50% of total natural rubber production in island. With no sufficient information on effectiveness in the use of materials and finance and then environmental impacts of RSS manufacture, this study aimed at assessing RSS manufacturing process adopting Material flow analysis, Material flow cost accounting and environmental Life cycle assessment in three factories in view of providing effective suggestions for making the system to be more cost efficient and environmentally friendly. Results indicated that manufacture cost, financial loss and GHG emissions generated by processing 1 MT of RSS were LKR 104,004 ± 6,336, LKR 1,007 ± 44 and 38.0 ± 2.1 kg CO2e, respectively (mean ± standard error). As an improvement option, installing single-day smoke dryers was proposed. This option could reduce firewood consumption per 1 MT of RSS by ca. 30% resulting in 0.1% and 14% of reductions in manufacture cost and GHG emissions, respectively. Implications of these findings are also discussed.

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.

Perspectives on Life Cycle Assessment Application and Research in Thailand Shabbir Gheewala; Thumrongrut Mungcharoen
Indonesian Journal of Life Cycle Assessment and Sustainability Vol. 1 No. 1 (2017)

Life Cycle Assessment (LCA) has been initiated in Thailand since the late 1990s with the first life cycle inventory (LCI) of the electricity grid mix and the offering of the first full graduate course. Since then it has come a long way through the development of the national LCI database and application in various research, industry as well as policy initiatives. LCA has been used extensively as an evaluation and decision tool in agri-food products, energy as well as many other sectors. Many graduate studies as well as research and industrial LCA projects have been performed. Related activities include the proliferation of carbon footprint labeling and application in green purchasing initiatives. Industry has been very actively participating in the carbon footprinting applications, some of them extending their interest to full LCAs for environmental performance evaluation and sustainability reporting. More recently, efforts have also been moving in the direction of looking at life cycle impact assessment methods from a Thailand perspective. Also, with interest in LCA from the policy making perspective, a capacity building effort has been initiated to train researchers in conducting LCA-related research on a sustained basis and ensure that Thailand keeps abreast of the international trends and discussions.

Dairy processing industry is one of the industries that give positive contribution to the economic growth, however it also contributes in many impacts on the environment, as well as milk powder product manufactured by PT X. The main objective of this study was to determine the most significant environmental impact caused by production and transportation of milk powder in bag 250 gram (Product X) using Life Cycle Assessment (LCA) methodology. The boundary of the LCA study is “cradle to gate”, including: materials production, materials transportation from supplier to the PT X factory, manufacture of milk powder in PT X, and distribution of the products from factory to distributor. Four impact categories will be calculated on this study: global warming potential (GWP), eutrophication potential (EP), acidification potential (AP), and photochemical oxidant creation potential (POCP). The impact assessment was calculated by software SimaPro v.8.3.2 faculty license, and the calculation result validated manually by Microsoft Excel. The result of environmental impact calculation showed the GWP, EP, AP, and POCP of 1 kg milk powder is 1.3245 kg CO2 eq/kg, 0.0033 kg PO43- eq/kg, 0.0066 kg SO2 eq/kg and 0.0020 kg C2H4 eq/kg. The material production subsystem has the highest environmental impact on GWP, POCP, AP and EP categories. In particular, production activity in PT X also contributes to GWP. An environmental impact reduction strategy can focus on reducing GWP with electricity usage efficiency and developing a material supplier selection plan with environmental impacts of material production as one of criteria.

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.
