Indonesia has 13,450 traditional market with 12.6 million traders in 2016. This type of markets has significant role and contribution for the national economic, the traders and the consumers. This research aims to investigate the sustainability of business model in traditional market. Study area are Pasar Pandansari in Balikpapan and Pasar Ibuh, Payakumbuh. Using the LCA methods, this study adopts some phases of International Standard Organization (ISO) 14040 consisting of setting up the goal and scope, and data inventory. Identified inputs include electrical energy, water, and materials/goods to sale. In addition, this study also investigates the economic aspect through the identification of the retribution income to the local government or management and environmental impacts. This study found that Pandansari Market has more extravagant inputs, especially in the consumption of electrical energy 78.5 kW/month (market stall) and 1,217 kW/month (kiosk) and this has an impact on environmental pollution through the exploitation of electrical energy in traditional market environments. The policy of using lights and electronic devices that have low kW and applying the concept of reward and punishment to traders can improve the sustainability of traditional market management.

Borobudur Temple is one of the world cultural heritage owned by the Indonesian nation. The existence of this Borobudur temple has an impact for the surrounding community, one of which led to new tourist destinations. This study aims to analyze the tourism potential of the area around Borobudur Temple in the concept of sustainable tourism. This research was conducted by using life cycle assessment perspective on tourism activity in the district level, including: the primary inputs (resources), process and outputs. The data collected from one of the Village Economic Chambers in the districts surrounding the Borobudur Temple regions, named Borobudur VEC. The Borobudur VEC has provided two products and services: tempe mendoan and lodging services. Those two business products have different characteristics. The tempe mendoan business process requires more raw material than the lodging service business process. Based on the result, emission tempe mendoan production is more than from lodging services.

The industry is a human activity established to process resources or materials into goods or products that humans can utilize. The dairy processing industry is one of the industries that process raw milk into various products, such as milk powder. The process of dairy processing industry activities not only produces a product but also contributes to environmental impacts. The main objective of this research determines the most potential environmental impact caused by the production process. The research will be conducted on milk powder products manufactured by PT X. The products chosen in this research are a product with a size of 40 grams per-sachet (product A) and product with a size of 200 grams per-sachet (Product B). The LCA research boundary is “gate to gate,” such as materials transportation from supplier, manufacturing process and management waste. The method used to determine the potential environmental impacts is life cycle assessment (LCA) method. Software SimaPro v.9.1 calculates the impact assessment. The calculations showed potential environmental impacts on product A and product B, such as Marine Ecotoxicity, Freshwater Ecotoxicity, and Human Toxicity. Based on the process stages of product A and product B, the potential environmental impact arises from the manufacturing process.

The health service industry involves activities that provide medical services (hospital), manufacture of medical equipment or drugs, and medical insurance services. Options of research methods to measure the impact of services on environmental aspects are available. One among which is life cycle analysis (LCA), the recently popular practice in Indonesia. This paper attempts to explore whether LCA could be fitted to the health service industry. A literature review would help in procuring related references from various publications accompanied by several research results and related studies. For describing the application of LCA in hospitals, several articles were collected, which were later arranged according to certain systematics from several sources. The LCA methodology used here consists of the following four stages: goal and scope definition, life cycle inventory analysis, impact assessment, and interpretation. The stages follow the International Organization for Standardization (ISO) 14040 and UNEP SETAC, 2011. Several studies using the LCA method in hospitals have reported specific profiles such as the management of biohazardous medical waste (BMW) and waste water. Several studies have also used LCA methods to assess specifically the environmental and health impacts of a specific component of the hospital or hospital activities. For example, studies have assessed the impact of equipment used in the form of containers, catheter, laryngeal mask, gowns and also infrastructures' facilities. The results of this study confirmed that the LCA method is suitable in health service industry, particularly in hospitals. Considering the merits and drawbacks involved in applying this method, one could further apply it to related health service issues.

Indonesia’s power generation capacity increased by 3% to reach 64.5 GW from 20017 to 2018, where 86% of the power plants that have been built are fossil-fueled. Limited resources and the impact arising from the production process will impact the environment, thus hindering sustainable development. Therefore, it is needed to set indicators that can be used to evaluate power generation’s sustainability to improve the community’s welfare. This research aims to find sustainability indicators that can be used to assess the electrical power generation system. A total of 51 articles from the snowball sampling approach was analyzed using a qualitative systematic literature review and quantitative method. We found 43 indicators covering economic, social, and environmental dimensions that can be used to assessed Indonesia’s electrical power generation’s sustainability.
