Judul: Strategi Bersaing Industri Kulit Di Sentra Industri Kulit Manding
Abstrak: Since 1979, Manding is the center of the leather industries which is wellknown by the people of Yogyakarta. Currently, Manding leather industries have decreased the competitiveness. This is characterized by the reduction number of export, the amount of production and the amount of annual sales. The purposes of this study were: (1) to formulate a strategy to raise the competitiveness. (2) to determine the priority strategies in enhancing the competitiveness of the leather industries in Manding. The tools used to analyze the data were the IFE matrix, EFE matrix that assisted by Porter’s Five Forces Model analysis, IE matrix, SWOT matrix, and QSPM matrix. The internal environment factors which influenced the company‟s strength consist of satisfied quality product; the big name of Manding; and the availability of raw materials. Meanwhile, the weaknesses of the industry were caused by the limitation of business network; low education of the workers; and problems of showroom. The external factor that increasing the opportunies in the industry was the impression of manding leather products are exotic, elegant and exclusive. From the quesioner we found that one of the popular product is stingray leather products In addition, the government also supported this by Ministry of Industry, ATK, and BBPPK. On the other hand, the external factors that threaten the industry were the existence of similar leather industries in vary scales; increase in fuel; and competition with substitute products. Prioritized strategies in enhancing the competitiveness of the leather industry Manding based on QSPM matrix in this study were: (1) an Internet-based marketing, the applications could be website making, join in the tradingforum, as well as the use of social media as a promotional tool and online transactions. (2) Provide the product knowledge and product trademarks. These mean for promotion, capture loyal customers, and expand the network marketing cooperation. (3) Optimize the function of the Manding craftsmen community. The craftsmen association namely Setyo Rukun expected to motivate and coordinate the craftsmen being active following the exhibition and to improve the ability to innovate products and administrative guidance for SMEs (Small and Medium Entities). As a results, these strategies are considered to cope the main issues in marketing and financial capital. Thus, by solving these expected to be able to improve the competitiveness in Manding leather industry center.

Judul: Green Productivity as an Approach to Address the Environmental Problem of Leather Tanning SMEs in Yogyakarta, Indonesia
Abstrak: The leather tanning industry is a most promising industry in Yogyakarta. However, the industry faces environmental problems due to poor environmental management practices. This study develops strategies to address the environmental issues of the impact of leather tanning SMEs in Yogyakarta. It identifies opportunities for improvement based on Green Productivity (GP) approach, and obstacles to formulating strategies for enhancing environmental performance. This study uses a Case Study approach using field observations and interviews with a number of leather tanning SMEs and industry experts. The results show that the SMEs in this sector adopt only a limited level of environmental practices. A set of GP options is proposed based on the observational evidence and expert judgements. Using an Analytic Hierarchy Process (AHP), a priority selected is to optimize the production processes of leather tanning SMEs. This study found that internal obstacles to green adoption included insufficient resources and infrastructure, low-skilled human resources, poor financial capability, lack of awareness, and poor organizational strategies. The external obstacles are significant and include inadequate law enforcement and government support, a small and limited market segment, and the lack of available green chemicals. These contribute toward poor environmental practices. To deal with these problems, this research proposes eight strategies for tackling the obstacles that prevent the implementation of leather tanning green practices. The strategies are divided into internal and collaborative. The internal strategies include encouraging enhanced product development processes and promote proactive and innovative strategies. Regarding their limitations, SMEs need stakeholder assistance to help solve their issues. A collaborative approach is crucial. Developing low-cost green technologies through R&D activities, developing best practice guidance and promoting its implementation, providing adequate facilities and machinery, identifying suitable suppliers to supply green chemicals, intensifying knowledge transfer of good environmental management, and establish a punishment and reward system are proposed for addressing the issues.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
