Low oil price environment impacted to business of Oil and Gas Company including PT. SDEC. However, PT. SDEC was able securing limited and fixed capital budget to drill well and had committed to drill certain well number to Government of Indonesia. When the initial 12 wells were completed with longer cycle time (average 9.9 days/well) than business plan (7.5 days/well) and also higher cost, the problem became more complex because company need to complete well as per commitment and in other hand no additional capital will be spent by parent company if actual expenditure exceeded the initial budget. Company assigned a team to solve the problem through Lean Six Sigma. Through strong collaboration among team, the project execution performance was improved (the Cp of drilling cycle time was improved from 0.06 to 1.08). As the result of this project save cost around $ 2.8 million.

Environmental pollution caused by the improper processing of electronic waste, especially from mobile phones, has increased drastically. Governments in developing countries, including Indonesia, have not been ready to face this problem. Informal groups are reacting very fast, growing and spreading evenly in many places to profit through reverse logistics activities. They dominate the markets of used electronic products. Today, eradicating these groups is impossible due to poverty, low education, and unemployment problems. Competing with them is also useless. Therefore, this research aims to find an engagement model between government and intermediary businesses, both formal and informal, for a sustainable purpose. Before determining the model, we must understand the intermediary businesses’ expectations. Therefore, we interviewed eight respondents that represent each business group and used customer value chain analysis to map them. We found forty-one expectations. Seven are the most common but are difficult to realize since they contradict government regulations. To cope with the urgency of the current situation, we concluded that the government should engage directly with the needs of these businesses, and we recommend three models of engagement i.e., empowerment, collaboration, and involvement.

Resources localization is one of the unique concerns of Appropriate Technology (AT) development. It has become a thought-provoking driver to related studies, meaning that there are wide-ranging opportunities to conduct researches, including ones on materials-related issues. Also, following the global concerns on environmental issues, assessment on environmental impacts imposed in AT life-cycle is interesting to be studied. Particularly, this study attempts to investigate potential impacts imposed by materials usage in AT. It is conducted by comparing and contrasting common approach in doing cleaner production to the implication of AT in providing cleaner application. This study aims to provide an integrated assessment framework for calculating environmental impacts from materials usage by incorporating the characteristics of AT life-cycle into account. The first finding points out the interdependency of cleaner production and cleaner application, meaning that there is a need of cleaner production in the manufacturing and construction process of any material/component/assembling in an AT; besides, the AT has to be designed to perform cleaner application, yet without reducing its performance and intention in localizing materials. Furthermore, the second finding pushes the first finding forward through an integrated environmental assessment diagram that covers materials production and application until the end of AT life-cycle, including disposal phase and predicted degradability of materials. By looking at common approaches that focused on the assessment of only cleaner production, this study is moving toward an integrated environmental assessment on an AT by covering both cleaner production and application to form a complete AT life-cycle assessment.

Rural commodities have become important in any kind of rural development. Considering the common difficulties happen in rural areas, and by looking at common uneven distribution of profit margin in many long supply chains of rural commodities, rural governances have begun to apply Appropriate Technology (AT) to pull such distribution back to rural communities as the producers of rural commodities. Such applications become more interesting in term of environmental forensics. Due to the different characteristics between environmental forensics on supply chain and AT, this study aims to integrate such characteristics into a single map of forensics. Characteristics of each kind of forensics are completely taken to deliver a holistic framework. Previous approaches in each forensics are explored to discover the potential integration. Based on such exploration, the cross-sections between forensics are carefully explained to avoid inaccuracy of assessment. The result provides an integrated framework to assess environmental impacts imposed both through supply chain and AT. By looking at previous researches, this study significantly contributes to the common understanding of environmental forensics on supply chain. Then, this study will be expanded by including cost-based approach to evaluate the unit emission per unit-distributed value added throughout a supply chain due to AT application.

Since the emerging of its idea circa four decades ago, Appropriate Technology (AT) had been proven as a comprehensive solution in a limited condition. However, practitioners & academia have different opinions with engineers on how an AT must be designed. Researchers had noted the crucial factors in the issue as such, and they gave a notion of the urgency for a dedicated design methodology for AT. This study, therefore, aims to provide it. Such methodology is developed by incorporating AT characteristics, fundamental issues in community empowerment, and the principles of existing design methodologies. The methodology emphasizes combination between bottom-up and top-down design approaches. It means that an AT must be started purely from local conditions rather than given technical specifications, and be given back to local people to be seamlessly integrated into their routines. It also underlines the crucial importance of community involvement throughout design stages. By looking at previous design methodologies that were developed based on pure Engineering Problem Solving (EPS), this study delivers a fresh and comprehensive one that covers surrounding issues and concepts to produce an AT based on the real meaning of technological appropriateness.
