"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."

"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."

Indonesia is a country that is included in one of the largest carbon dioxide emitters in the world. The cement industry is an industry that is included in the IPPU (industrial process and product used) sector which contributes to greenhouse gas emissions in that sector compared to other industries. Cement is one of the raw materials needed for a building infrastructure. Indonesia, which is promoting the development of national infrastructure, must pay attention to the environmental impact of the cement production process on the environment. Thus, this study was conducted to analyze the environmental impact resulting from the cement production process using the life cycle assessment method. There are two stages of production that have the biggest impact, namely the klin process and the finish mill & pack caused by burning coal. This study makes a comparative analysis between the current condition and the company's target in increasing the use of alternative fuels by 15% by identifying risks that have the potential to arise and making risk prevention mitigations."

Plastic waste problem in Jakarta increasingly piling up, it is estimated that in 2021 TPST Bantar Gebang is no longer able to accommodate the garbage of citizens of Jakarta. The plastic waste itself is dominated by post-use consumer from the FMCG sector. In fact, Law No. 18/2008 on Waste Management Article 15 regulates the obligation to manage consumer waste that is difficult for the company to decompose, but very few implement it. This research discusses the environmental impact of a product’s life cycle and looking for a greener life cycle. This research determines the environmental impact of every manufacturing and recycling process, then determines the process to be developed to be more environmentally friendly and the costs involved in each stage. Life Cycle Analysis (LCA) is then developed to analyse environmental effect and cost analysis is developed to calculate cost factors. The results showed that using environmentally friendly SiO2 ink would reduce 13.06% environmental impacts such as; climate change, acidification, respiratory problems, and fossil fuels then reduce overall costs by Rp. 24,628.52 per 1000 bottles every 1,000 product cycles."
