Penilaian Daur Hidup (Life Cycle Assesment) Produk Kina Di PT Sinkona Indonesia Lestari

PT Sinkona Indonesia Lestari adalah anak perusahaan dari dua Badan Usaha Milik Negara yaitu PT Kimia Farma dan PT Perkebunan Nusantara VIII. PT Sinkona Indonesia Lestari (SIL) memproduksi cinchona atau yang dikenal dengan tanaman kina yang merupakan tanaman obat yang mengandung quinine yang dikenal sebagai obat malaria. Cinchona diekstraksi untuk diambil kandungan quinine. Setiap tanaman cinchona mengandung kadar quinine 3-14%. Penilaian jumlah emisi yang dikeluarkan selama proses produksi dapat dilakukan dengan menggunakan metode Life Cycle Assessment (LCA). Selain itu, LCA juga akan digunakan untuk melakukan perbaikan dalam siklus hidup produksi yang bertujuan untuk mengurangi emisi. Tujuan penelitian ini adalah untuk menilai dampak lingkungan berupa gas rumah kaca (GRK), serta upaya untuk mengurangi dampak lingkungan tersebut. Tahapan dari penelitian ini adalah menentukan tujuan dan ruang lingkup, analisis inventori daur hidup, analisia penilaian dampak lingkungan, dan analisis interpretasi hasil. Dari analisis LCA, untuk menghasilkan 1 ton garam kina diketahui menghasilkan dampak lingkungan berupa emisi gas rumah kaca sebesar 47.3815 CO2(eq) pada tahun 2013. Pada tahun 2014 emisi gas rumah kaca mengalami penurunan sebesar 53.4217 CO2(eq). Pada 2015, 1 ton garam kina menghasilkan emisi gas rumah kaca sebesar 53.5435 CO2(eq) dan pada 2016 menghasilkan 45.7901 CO2(eq). Penelitian ini juga menemukan bahwa pemanfaatan ampas kina dan penggantian minyak residu menjadi bahan bakar solar dapat mengurangi emisi. Pembuatan briket dari ampas kina dapat menurunkan emisi gas rumah kaca sebesar 0,14 % pada tahun 2015 dan menghasilkan energi alternatif sebesar 1.612 TJ. Alternatif lain adalah penggantian minyak residu menggunakan bahan bakar solar (IDO) pada bahan bakar boiler, yang dapat mengurangi emisi sebesar 11.9% atau 6.3518 ton CO2 (eq) /ton garam kina.

Implementation of Life Cycle Assessment on Green Tea Process at Pt Pagilaran - Factory Samigaluh

Life Cycle Assesment is a method to assess environmental aspects and potential effects which are connected with product, process or service. This method is conducted by using compilation and data analysis on input and output of production system, evaluation of environmental potential effects, intrepretating on data compilation and analysis, and assessment results on effects due to the goal of LCA. The research was conducted at PT. Pagilaran – Samigaluh and aimed to implement LCA on tea product. It was done by direct observation on all process steps, from harvesting tea leaves until tranportation to final storage at manufacturing. The results showed that for producing one kilogram green tea at this factory it was needed energy 68,534.14KJ and released emmissions from fuel were 56.53 g CO2;7,07 g HC; 2,12 g NOx, and 0.053 g Pb. Emmission from processing steps were 18.37 ppmCO2; 321.31 ppm CO; 22.75 ppm HC; 93.08 ppm NOx; 15.17 ppm SOx and 0.12 g ash. Furthermore for transporting tea leaves some gases were released as follow 15.36 g CO;9.66 g HC; 65.46 g; NOx; 5.20 g SOx and 2.198 g ash. Keywords: Green Tea; Energy; LCA; Emissions

Enviromental impact comparative tool based on life cycle assesment = Herramienta comparativa de impacto ambiental basada en método de análisis de ciclo de vida

The Life Cycle Assesment LCA is a method used to quantify the environmental impact of a product or service along their life cycle. The tool offered is based on the LCA and will provide an easier and a visual comparative report to assess the impacts generated by two different facade's construction solutions. The source of the results are feed from a database composed of data from the Environmental Product Declaration which is a mechanism used for environmental communication. The Environmental Product Declaration is the most prestigious and well recognized mechanism due to the objectivity incurred on the data collection process. The tool enables selecting various facade's configurations through the combination of different layers. It was decided not to evaluate the actual environmental impacts with the aim of building a decision making tool where the technician will be able to go in depth for the specific impact of each material and identify and approach the important focal points using the comparative report. The LCA simplified tools represent a compromise for a precise evaluation, but it will be necessary to be realistic and transparent about their limits as stated at the end of the paper.ResumenEl Análisis de Ciclo de Vida (ACV) es un método que sirve para cuantificar el impacto ambiental de un producto o servicio durante su ciclo de vida. La herramienta que se presenta pretende, basándose en este método, proporcionar de forma simplificada y visual un informe comparativo de los impactos que generan dos soluciones constructivas de fachadas. Los resultados se nutren de una base de datos formada por datos de Declaraciones Ambientales de Producto, mecanismo de comunicación ambiental que goza actualmente de mayor prestigio debido a la objetividad en el proceso de obtención. La herramienta permite seleccionar distintas configuraciones de fachada mediante la combinación de diferentes capas. Se ha decidido no ponderar los impactos con el fin de la herramienta sea un asistente de decisión, donde el técnico pueda profundizar hasta el impacto específico de cada material para poder identificar los focos graves de impacto y actuar en consecuencia, teniendo siempre como referencia el carácter comparativo del informe. Las herramientas de ACV simplificadas representan un compromiso en la precisión de la evaluación, pero es necesario sean realistas y transparentes respecto a sus límites, que se presentan al final del escrito.

Energy Production from Natural Gas: Evaluation of Pontential Environmental Impacts Using Life Cycle Assesment Approach

Nowadays, sustainability is one of the main driving forces for worldwide economic growth especially in energy production. Conbustion of fuel such as natural gas for energy production not only produce electricity but also impacts to environment. In order to assess the environmental impacts of the natural gas power plant, study of life cycle assessment (LCA) has been carried out based on the data obtained from natural gas (NG) power plant in Johor, Malaysia. Data validation has been done by comparing the result with other assessment using the data available in the database. This paper presents the results of the LCA. From this study, it was found that there are insignificant differences in terms of the potential environmental impacts between the LCA study conducted using the data from the NG power with the assessment conducted using data from the database.KeywordsLife cycle assessment, sustainability, energy, natural gas
