Sebuah kajian LCA melibatkan pengumpulan data dan perhitungan untuk mengukur input dan output atau beban lingkungan dari sistem produk yang relevan. Beban lingkungan, disini merupakan sumber daya yang dikonsumsi dan emisi dilepaskan ke lingkungan. Makalah ini adalah bertujuan untuk memberikan penjelasan dan gambaran singkat tentang metode LCA. Perbedaan antara metode LCA dan perangkat metode analisis lingkungan yang lain dibahas untuk memberikan informasi tentang alternatif pilihan untuk perbaikan kinerja lingkungan dari produk Agroindustri dengan pemanfaatan biomassa. Dalam tulisan ini diuraikan potensi LCA sebagai perangkat/alat untuk analisis lingkungan, dan dibahas kemungkinan aplikasinya untuk meningkatkan daya saing industri Indonesia, khususnya daya saing dibidang Agro-industri indonesia.

ERL concept is arranged by considering both market and business aspects. Every aspect is divided into four phases and each of them consists of some indicators. Analytic Hierarchy Process (AHP) is used to develop the ERL in calculating the weight of every single aspect and indicator. Interval scale between 0 and 4 is also applied in indicator assessment. In order to calculate ERL, score in every indicator and the weight of both the aspect and indicator are considered. ERL value is able to show in detail the innovative product readiness level from economic sight, market and business aspect. There are four levels in Economic Readiness Level scheme which are investigation, feasibility, planning and introduction.

The measurements were carried out in the dry and rainy seasons. The results showed biogas production rates in the range of 25.9-133.4 L/m 2 /h, and an average biogas production rate of 67.2 L/m 2 /h. Biogas production rate was affected not only by season and collection position in the lagoon, but also by time of gas collection. From the average biogas production rate in each month, the methane emission factor in pond No. 4 could be estimated at 0.16-0.31 g CH4/g COD removed. This variation was observed due to changes in water temperature. This study showed the importance of temperature changes for the baseline measurement of greenhouse gas emissions determined by the methane emission factor in CDM projects

However, there are plent}T of environmenta1 arguments of this only one power plant that using coal energy for generating clcctricity. Therefore, ullderstanding the environmcntal impacts of the power plant system is necessary in order to find possible and suitable ways for waste reduction and system improvement. The aim of thc stud}, is first to apply Lifk Cycle Assessment (LCA) with Numerical Eco-Load Total Standardization (A･E71S), which used for evaluating thc environmenta1 burdens by identifying and quantifying energy and materials used and waste Teleased to environment based on the balance ef L & R (Loader and Rcceiver) tolerance. And the Life Cycle Invcntory (LCI) of the power plant system has becn developed. Tlie second is to determine the pcrformance cost by using Life Cycle Costing analysis (LCC) and to compare ",ith other types of coal-fired generating systems. As the resulg environmental load and economical cost for comparative power plants are discussed from life cycle thinking point of view to indicate for the better ecological and economical coal-fired power generation system forThailand.

The customized computer code is developed to evaluate the overall function of alternative energy systems from the performance pattern corresponding to the selected energy attributes. For the purpose of exploring the applicability and the effectiveness of the proposed model, the model is applied to decision problems concerning the selection of energy sources for power generation in Japan. The set of nine energy alternatives includes conventional and new energy technologies of oil fired-, natural gas fired-, coal fired-, nuclear power, hydropower, geothermal, solar photovoltaic, wind power and solar thermal plants. Also, a set of criteria for optimized selection includes five areas of concern; energy economy, energy security, environmental protection, socioeconomic development and technological aspects for electric power generation. The result will be a ranking of alternative sources of energy based on the Euclidean composite distance of each alternative to the designated optimal source of energy.

Those power plants hold the share of Electricity Generating Authority of Thailand (EGAr) about 52.5% and 22.7% respectively classified by gross electricity production and by the type of fuel used in 2000. Therefore, it is necessary to understand the environmental influences from electricity production systems, in which could be instructed the component of enyiTonmental plan for reducing emissions and resources consumption. The aim of the study is to apply Life Cycle Assessment (LCA) with Nunierical Eco-Load Tbtal Standardizatien (AETIS), which is used for eva]uating the environmenta1 burdens by identifying and quantifYing energy and materials used and-,aste released to environment. And the Life Cycle Inventory (LCI) and Lifk) Cycle Costing (LCC) of the power plant systems have been cleveloped and estimated. As a result, the LCA=IVLE7S point ofview was discussed for funher ecelogical power generating systems which will be acting more environmental fiiendly in the futurc.
