The progressive competition among industries and the increase of customer expectation will lead the progressive efforts in reducing the cost of production and logistic activities in the future. The companies (mass production, job shop and service industries) are forced to tighten their production process effectively by cutting the unnecessary activities in logistic flow, delete dummy and redundant elements, specializing the core business, and eliminate the wastes to simple and make their production process is more competitive. The lean concept could be the alternative way to reduce the main wastes: inventories and production cycle time. Eventhough it is very expensive to implement the lean production in the shop floor production, but the waste elimination and continuous improvement as the main key of the lean thinking has promised a significant improvement and profit for companies which implement the concept. The tools that could be used as methods to make the production process leaner such as just in time with kanban card system, kitting principle, collaborative scheduling and production plan, group technology, cell manufacture design and line balancing are well implemented in the worldwide. The efforts in leaning production will continue due to the lean thinking basically try to make the system better and believe that there is no best system but there is always better system.

This research was expected to apply QFD in the development process of product which refers to consumer request, so that the result of scheme process really answers market requirement. The research methods were conducting product survey in field, making questionaire of consumer request, spreading questioner, checking returned questioner data, and the processing questioner data by QFD. The matrix of concept assessment shows that concept A (funnel one semi automatic) gets value 0.238 and 16510%; concept B (funnel two semi automatic) gets value 0.211 and 16630%; concept C (funnel two semi automatic/manual) gets value 0.203 and 18470%; so that amongst the third concept, the one which is appropriate to be proceeded to the production department is only concept A.

Information sharing in supply chain has emerged as one critical factor in maintaining company's responssiveness. This ability is needed to overcome both the supplier and customer requirements in sharing their data to accomplish their operational routines. A lot of efforts have been devoted in such research area including XML (eXtensible Markup Language) technology. However, a stepwise approach on how to utilize this advance technology is still lacking. This paper proposed a lightweight approach to implement XML in information sharing firmly. The main XML characteristics will be exploited so that the advantages of utilizing this mark up language may be highlighted. Based on these important remarks a lightweight approach of implementing XML is possible to be composed. The expected outcome is a step-by-step guidance for data exchanger to utilize XML simply but precisely and accurately. A case study of information sharing in commerce is elaborated to enhance our understanding on how to implement this approach in real domain problem.

Health represent essential requirement these days. For that on duty in charge have to have yardstick to know efficiency ;level and health service productivity. Measurement of efficiency as productivity index must be done objectively, so that result of measurement can be made input to progress of health of society. Target of research was to make a model assessment of efficiency in order to determination of productivity every health service and determine repair plan to inefficient service. Problem solving used Data model of Envelopment Analysis (DEA) approach. DEA was used to measure productivity and efficiency with input multi and of multi output. With existence of real correct measurement - objective correctness, expected will give instrument to Health department to give satisfaction to wide [of] society. From result of data processing, will be obtained value of technical efficiency for the each Decision Making Unit (DMU) was less efficient, and some repair goals which must reach. Stipulating of peer of group to less efficient DMU will give direction to repair program.

The problem of quality is often found in limestone combustion of small and medium central industry in Manyar Regency, Gresik, in which, the quality of limestone is defected and has high variation of CaO. One of many methods to improve it is by applying Robust Design from Taguchi, them, its result is socialized in a central industry as a reference for those who conduct combustion in producing material. This study found four controlled factors that each of them consists of two levels that can influence the quality of limestone: A) raw material (level 1 = yellow limestone; level 2 = white limestone); B) Combustion material (level 1 = wood & rubber; level 2 = wood and gerbage sawmill); C) Combustion length of time (level 1= five days; level 2 = four days); D) Combustion temperature (level 1 = ± 800° C; Level 2: ± 875° C). Meanwhile, the optimal combination factor level to improve the quality of limestone is A2, C1, D1, and B2. If factor of combination level is applied, the number of defected good in each combustion can be predicted as much as 1,41% and the defected variable among combustion is 0.37%.
