<p>Potensi perikanan yang besar di kawasan perikanan Muncar Banyuwangi menjadikannya sebagai dasar munculnya berbagai industri perikanan. Perkembangan industri ini memiliki dampak yang signifikan tehadap lingkungan. Tujuan dari penelitian ini untuk mengidentifikasi input dan output yang dihasilkan dari proses produksi, menghitung besaran dampak dan merumuskan strategi perbaikannya. Penilaian daur hidup atau Life Cycle Assessment (LCA) merupakan metode yang digunakan untuk menganalisis dampak lingkungan yang disebabkan oleh pengadaan bahan baku, proses produksi dan penggunaan produk. LCA terdiri dari 4 tahap sesuai dengan ISO 14040 yaitu<em> Goal and Scope Definition, Inventory analysis, Life Cycle Impact Assessment dan Life Cycle Interpretation</em>. Studi LCA dalam penelitian ini menggunakan pembatasan masalah <em>Cradle to Gate</em>. Penilaian siklus hidup produk perikanan berfokus pada pemanasan global. Hasil penelitian menunjukkan bahwa emisi Gas Rumah Kaca (GRK) merupakan dampak potensial terbesar yang dihasilkan oleh industri pengolahan perikanan. Emisi CO<sub>2</sub>eq dari pabrik pengalengan ikan sebesar 86,86 CO<sub>2</sub>eq/tahun, sedangkan dari industri pengasinan ikan sebesar 28,76 CO2eq/tahun. Total emisi CO<sub>2</sub> dari kegaiatan pengolahan hasil perikanan sebesar 115.62 CO2eq/tahun. Sumber penghasil emisi berasal dari solar <em>I</em><em>ndustrial Diesel Oil</em> (IDO), solar <em>Automotive Diesel Oil</em> (ADO) dan listrik. Upaya penurunan dampak lingkungan dilakukan dengan <em>pertama</em>, menggunakan energi listrik yang berasal dari pembangkit listrik tenaga air dan panas bumi. <em>Kedua, </em>dengan mengolah limbah industri perikanan seperti minyak ikan menjadi biodiesel yang lebih ramah lingkungan untuk diversifikasi penggunaan solar pada unit proses. <em>Ketiga</em>, dengan mengefisienkan sistem produksi melalui perubahan pola perilaku maupun standar dalam pelaksanaan produksi.</p>

Perkembangan perkebunan kelapa sawit di Indonesia mengalami peningkatan pesat. Dibalik perkembangan pesat komoditas kelapa sawit, bermunculan masalah dan isu negatif mengenai perkebunan kelapa sawit sebagai penyebab kerusakan lingkungan dan peningkatan emisi Gas Rumah Kaca (GRK). Penelitian ini bertujuan untuk menganalisis emisi GRK yang ditimbulkan dari kegiatan perkebunan kelapa sawit dengan menggunakan metode Life Cycle Assessment (LCA). LCA adalah suatu metode untuk melakukan analisis dan evaluasi secara menyeluruh dari dampak lingkungan dalam siklus hidupnya. Tahapan metode LCA adalah goal and scope definition, life cycle inventory, life cycle impact assessment, dan life cycle interpretation. Hasil penelitian menunjukkan bahwa emisi GRK yang ditimbulkan dalam kegiatan perkebunan kelapa sawit selama 1 siklus berbeda-beda. Emisi GRK yang ditimbulkan pada fase TM (umur tanaman >3 tahun) menjadi yang terbesar dengan rata-rata 1887,64 kg CO2-eq/Ha, sementara emisi GRK pada fase TBM (umur tanaman 0-3 tahun) sebesar 989,63 kg CO2-eq/Ha. Sumber terbesar penyumbang emisi berasal dari kegiatan pemupukan. Pada fase TM, kegiatan pemupukan menyumbang emisi GRK sebesar 920,22 kg CO2-eq/Ha dengan jenis pupuk paling dominan menyumbang emisi GRK adalah pupuk urea dan MOP yaitu sebesar 369,67 kg CO2-eq/Ha dan 179,56 kg CO2-eq/Ha.

AbstractIn 2013 the population of dairy cattle in Indonesia had reached 636,000 head with a 4.61% growth rate per year. The inputs were energy, water, and feed. These inputs produced outputs, such as emissions, solid waste and liquid waste. This research compared the maintenance systems in modern farms and local farms. The data were collected from 30 local farmers and one modern farm. This research used the life cycle assessment (LCA) method. LCA is based on ISO 14040. LCA consists of several stages: the goal and scope definition, inventory analysis, impact assessment, and interpretation. This research used the cradle to gate concept and fat corrected milk (FCM) as the function unit. The impacts of these activities could generate global warming potential (GWP), acidification potential (AP), and eutrophication potential (EP). The calculations showed that the systems in local farms had the greatest emissions result over all impacts. In the case of local farms, the GWP was 2.34 kg CO

Goal And Scope Definition

Life cycle assessment is a quantitative method to analyze the environmental impact that consists of four main activities: goal and scope definition, life cycle inventory, life cycle impact assessment, and interpretation. The application of the life cycle in palm oil industry are very important and already conducted by many researchers. However, the most difficult task in life cycle assessment are the life cycle inventory. In this research, this study proposed the software to support the life cycle inventory in palm oil production. The result of the study was the conceptual design of the life cycle inventory software.

Abstract The aviation industry has been growing continuously over the past decades. Despite the current Covid-19 crisis, this trend is likely to resume in the near future. On an international level, initiatives like the Green Recovery Plan promoted by the European Union set the basis towards a more environmentally friendly future approach for the aero-industry. The increasing air traffic and the focus on a more sustainable industry as a whole lead to an extensive need for a more balanced assessment of a products life cycle especially on an ecological level. Blisks (or IBRs) remain a central component of every current and very possible every future aero engine configuration. Their advantages during operation compared to conventional compressor rotors are met with a considerably complex manufacturing and production process. In the high-pressure compressor segment of an engine, the material selection is limited to Titanium alloys such as Ti6Al4V and heat-resistant Nickel-alloys such as Inconel718. The corresponding process chains consist of numerous different process steps starting with the initial raw material extraction and ending with the quality assurance (cradle to gate). Especially the central milling process requires a highly qualified process design to ensure a part of sufficient quality. Life-Cycle-Assessments enable an investigation of a products overall environmental impact and ecological footprint throughout its distinct life-cycle. Formal LCAs are generally divided by international standards into four separate steps of analysis: the goal and scope definition, the acquisition of Life Cycle-Inventory, the Life-Cycle-Impact-Assessment and the interpretation. This content of this paper focuses on a general approach for Life-Cycle-Assessment for Blisk manufacturing. • Firstly, the goal and scope is set by presenting three separate process chain scenarios for Blisk manufacturing, which mainly differ in terms of raw material selection and individual process selections for blade manufacturing. • Secondly, the LCI data (Life-Cycle Inventory) acquisition is illustrated by defining all significant in- and outputs of each individual process step. • Thirdly, the approach of a Life-Cycle-Impact-Assessment is presented by introducing the modelling approach in an LCA-software environment. • Fourthly, an outlook and discussion on relevant impact-indicators for a subsequent interpretation of future results are conducted.
