  • Performance of Sustainable materials continues through using of recycled waste construction materials to minimize the utilization of the natural resources. The cement industry is a major source of CO2 in the atmosphere which is the main cause of global warming. Replacement of OPC with other sustainable cementitious materials has been the most interesting area of researches. This investigation focuses on the properties of alkali-activated mortar with the different replacement ratios of ceramic tile powder (CTP) by fine soil powder (FSP) (0 to 100)% and different molarities of sodium hydroxide concentrations. The experimental program was conducted by examining the compressive strength, water absorption, and water sorptivity. The results showed that the compressive strength of the specimens at age of (28, 56, and 90 days) increases with an increase in the amount of fine soil powder content and decreases at the age of 120 days. Also, minimum water absorption at the age of 90 days was found in the mixes containing 100% fine soil powder. However, fine soil powder replacement had a negative effect on the sorptivity and water absorption values at the age of 120 days. On the other hand, the 12M sodium hydroxide concentration was considered the optimum concentration compared to other concentrations.

  • In this paper, we conducted an empirical study on the economic value of Palutungan Resort, Gunung Ciremai National Park (Indonesia), using an individual travel cost method. Gunung Ciremai is the highest mountain in West Java Province which has high biodiversity and constitutes the home range of the endangered species, Nisaetus bartelsi and leopards. Using the individual travel cost method, we estimated the annual consumer surplus of ecotourism for Palutungan Resort to be approximately $19, while its total economic value was $0.23 million. However, Palutungan Resort does not benefit exclusively, because the total economic value is divided diversely among the central government (non-tax revenue), local government (taxes), and local communities, while the transportation agencies, retailers, and gas station companies also reap some valuable benefits. In regard to the benefit allocation, all of the associated parties should participate in the conservation and preservation of natural resources in Palutungan Resort to improve the ecotourism services.

  • Tourism is one of the largest and fastest growing industries in the world, and is a major industry in many developed and developing countries. It is an increasingly important source of income, employment and wealth in many countries. However, its rapid expansion has also had detrimental environmental and socio-cultural impacts over many regions. Like tourism, the rapid growth in cruise tourism has also put greater pressures on environmental and cultural resources in cruise-ship ports of call. Through this paper, we would like to argue that more emphasis should be given to minimize national and international environmental impacts originated from cruise tourism with preparing infrastructures for sustainable tourism.

  • Purpose: This study seeks to establish the environmental damage theory applicable to Kenya. The analysis is based on annual data drawn from World Bank on carbon dioxide emissions (CO2e) and gross domestic product per capita (GDPPC) for Kenya spanning 1963 to 2017. Research Methodology: The study adopts explanatory research design and autoregressive distributed lag model for analysis. Results: The results revealed a coefficient of -0.017 for GDPPC and 0.004 for GDPPC squared indicating that economic growth has negative effect on CO2e in the initial stages of growth but positive effect in the high growth regime with the marginal effect being higher in the initial growth regime. The findings suggest a U-shaped relationship consistent with Brundtland Curve Hypothesis (BCH). Conclusions: The findings emphasize the need for sustainable development path that enables present generations to meet own needs without compromising the capacity of future generations to meet their own. Sustainable development may include, investment in renewable energies like wind, solar and adoption of energy efficient technologies in production and manufacturing. The study concludes that BCH is applicable to Kenya and that developing affordable and effective mechanisms to boost sustainable development implementation is necessary to decrease the anthropogenic impact in the environment without any attendant reduction in the economic growth.

  • The essential purpose of this study is to propose strategies for developing micro-, small-, and medium-sized enterprises (MSMEs) to realize sustainable competitive advantage by applying the SWOT analysis method. Thus, the main problems investigated in this study are: a) around 60-70% of MSMEs in Kulonprogo regency do not yet have access or financing from banks; b) lack of knowledge of production technology; c) in general, MSMEs business actors are still incorporated legal entities; d) MSMEs do not have a good financial administration and management system; e) coordination between MSMEs stakeholders has not been integrated; f) limited facilities and infrastructure of MSMEs, primarily related to technological tools; and g) limited access to raw materials so that MSMEs often get low-quality raw materials. This study employed a survey method with questionnaires and interviews. By using the Slovin tools sampling technique, the number of samples was 39 MSMEs in Kulonprogo Regency, Yogyakarta, Indonesia. The results of this study confirmed that the Kulonprogo MSMEs should pay attention to seven aspects of business management to achieve sustainable competitive advantage. The seven aspects are: 1) business strategy; 2) human resources; 3) information technology; 4) products; 5) promotion; 6) cooperation; and 7) corporate social responsibility (CSR).

  • The fashion industry is considered hazardous and a threatened to the environment. Due the negative perception, the industry should focus on sustainability as a social role. Therefore, several redesign fashion collaborations mainly focusing on renewing abandoned resources are already in place. The research method was based on previous studies, and 3 characteristics were derived: Redesign collaboration between fashion companies, Redesign collaboration between fashion & heterogeneous industries, and Redesign collaboration between the fashion industry & non-profit organizations. Those 3 characteristics were reviewed using 4 criteria. First, to establish and maximize the sustainable brand image and to be the best examples in environmental management, the organization endeavors to collaborate with various industries, institutions, and designers. Second is the expansion of the customer network through the spread of value consumption. Third is the creation of new values through a resource circulation structure. This means that the resource circulation structure system helps the partners to minimize on wastage. Fourth is the spread of de-boundary lines and the possibility of brand growth. Through collaboration with other industries, the boundaries of materials used in the fashion industry started to blur, thus expanding the continuous brand growth potential. The study derived the characteristics of redesign collaboration by systematically analyzing the cases. Further, the study looks forward to analyzing the characteristics of the products processed by redesign fashion collaborations in future research.

  • The fashion system has been criticized for relying on a linear economy to reduce short-term costs and increase profits. Meanwhile, the circular economy strives to expand the value chain through a closed loop for companies, society, and the environment by separating consumption from resources. This study aims to elucidate the strategic characteristics of the technological measures that fashion companies and brands are trying to innovate into a sustainable fashion system on the basis of the circular economy concept. Thus, we conducted case studies by dividing the value chain of the fashion system into design, production, and consumption to identify the technological development of the circular fashion system from a technologization perspective that incorporates technological values. First, design appeared to strengthen emotional durability, design and process with circulation in mind, and fashion product digitalization. Second, production manifested itself as material development for the new fiber economy, improvement of non-environmental processes, and customization of demand-driven, responsive production. Third, consumption was the spread of the environmental consumption culture through the sharing economy platform, the realization of a virtual wearing experience to prevent rapid disposal, and the provision of information on sustainable consumption.
