Indonesia is still an energy importer, especially in the form of crude oil and fuel products. Reducing fossil energy production and commitments to reduce greenhouse gas emissions encourage the Indonesian government to support the role of new and renewable energy. The production of palm oil-based biodiesel is faced with several environmental problems from releasing emissions. The purpose of this study was to develop LCI for biodiesel production, analyze environmental impacts including CO2(eq), acidification and eutrophication emissions and develop a life cycle concept for biodiesel production from palm oil. This research method is quantitative (LCA-AHP) and qualitative. The results of this study are LCI in 1 ton of biodiesel consisting of 5.67 tons of fresh fruit bunches, 1.17 tons of CPO; and POME 3.47 m3. The total emission of CO2(eq) is 1489 Kg CO2(eq), eutrophication 1.115 Kg PO43-(eq) and acidification 3.058 Kg SO2(eq). The concept of a biodiesel production life cycle can be applied by utilizing POME waste."

"The focus of this research is to analyze potential environmental impact in the supply chain of palm oil biodiesel industries. Simple Life Cycle Assessment (LCA) is applied to analyze impacts, produced by the three main units in the supply chain of Palm-Oil-based Biodiesel, which are Palm Plantation, CPO mill, and Biodiesel Plant. We developed LCA calculation model using spreadsheet software, used to assess a number of input scenarios to evaluate the best scenario, in variation of: land quality, land area and the rate of clearing, land clearing technique and type of the original land. The biggest potential environmental impact is the contribution to global warming impact which emissions are produced mostly from unit plantation. Although plantation has biggest potential to contribute to environmental impact, it also gives biggest reduction to global warming impact. In general, the biggest environmental impact in the LCA category is climate change, followed by photo-oxidant formation and eutrophication. The biggest impacts in the supply chain are from the plantation, especially when choosing the right technique for land clearing. In addition, due to LCA linearity nature, the scenario that we tested does not change the total accumulative environmental impacts."

Reusing granular by-product materials from agricultural, construction and demolition waste of buildings as a substitute for natural coarse aggregate could alleviate environmental issues in the construction industry. This study aimed to determine the greenest concrete among three types of concrete: oil palm shell aggregate concrete, natural aggregate concrete, and recycled aggregate concrete, produced on a laboratory scale in a form of beam. These types of concrete were ranked according to environmental impacts, mineral resource depletion and waste generation from their production. A life cycle assessment (LCA) was conducted to analyse its environmental impacts, the effect of transporting oil palm shell aggregates and the allocation effect between the production of natural aggregate concrete and recycled concrete aggregate. Afterwards, the carbon dioxide uptake of the concretes was estimated for 25 years of use and ranked based on environmental criteria using the VIKOR method. Results have shown that recycled aggregate concrete can be presented as environmentally friendly concrete that meets the compromise solution requirements."

"Perkembangan ekonomi dan industri melaju tanpa adanya rencana yang berkelanjutan, hingga pola konsumsi dan produksi manusia saat ini membahayakan lingkungan dan sumber daya alam. Menjawab pada permasalahan ini, berbagai bentuk pendekatan lahir dan salah satu diantaranya adalah life cycle approach yakni. Penggunaan life cycle approach sangat populer di negara-negara anggota Uni Eropa, sehinga perkembangan konsep, instrumen dan program dari life cycle approach sangat pesat. Penerapan pendekatan ini menunjukkan hasil yang nyata dalam pengurang emisi dan penggunaan sumber daya alam. Untuk mengatasi permasalahan lingkungan, pendekatan command-and-control tidak lagi cukup hingga digunakan penaatan sukarela. Berkaitan dengan penerapan life cycle approach, program penaatan sukarela di Uni Eropa menggunakan Life Cycle Assessment yang merupakan instrumen atau metode dengan kerangka holistik yang berfungsi untuk mendeteksi potensi-potensi dampak lingkungan atas emisi yang dikeluarkan suatu produk sepanjang tahapan pada siklus hidupnya. Penggunaan Life Cycle Assessment dikenal dalam pembentukan kriteria produk untuk suatu skema ekolabel. Di Indonesia, kriteria produk dari program ekolabel belum menggunakan Life Cycle Assessment tetapi Life Cycle Assessment itu sendiri sudah digunakan oleh berbagai perusahaan di Indonesia. Penggunaan Life Cycle Assessment sangat dimungkinkan di Indonesia apabila program ekolabel berkualitas dan iklim pasar di Indonesia sangat mendukung produk dengan logo ekolabel.

The economic and industrial development grows without any sustainable plan, in which the current patterns of consumption and production have a devastating impact on the environment and natural sources. To address this matter, various forms of approaches was made and one of them is the life cycle approach. The use of life cycle approach is very popular in the European Union, where the concepts, tools, programmes of the life cycle approach are rapidly developing.

To address environmental problems, voluntary compliance was made. In relation to the adoption of life cycle approach, a voluntary compliance program in the EU uses the Life Cycle Assessment which is a holistic method used to identify potential environmental impacts of a product through the emissions it produces throughout its life cycle. Use of Life Cycle Assessment in a ecolabel program is seen when forming the criteria of a product.

In Indonesia, the forming of the criteria is not yet based on Life Cycle Assessments but instead many Life Cycle Assessments were conducted by various companies in Indonesia. The use of Life Cycle Assessment is possible in Indonesia if the ecolabel programme has quality and economic climate in Indonesia strongly supports ecolabelled products."
