Military standard 105D is a sampling method developed by United States Ministry of Defense. The background of this method development was to accommodate fulfillment of producer and consumer expectation on the product quality inspection with acceptance or rejection lot mechanism. There was three level of inspection based on MLT STD 105D, normal, tightened and reduced. The choice on inspection level, based on tendency of increasing or decreasing defect amount that founded. PT. GE Lighting used a single sampling inspection method with constant sampling amount of 80 pcs for every lot with 500 pcs. This research was to decide the alternative sampling method using MIL STD 105D. Based on the amount of proposal sampling, thus the decreasing percentage on the sample amount from the recent sample of 80 pcs is 37,5% for normal inspection, 40% for reduced inspection and 40% for tightened inspection.The amount sample on each category for the three level inspection on single sampling & double sampling proposal have probability below the producer risk (5%) and consumer risk (10%), so the sampling proposal can accommodate both producer & consumer risk.

PT. IKAD is a company that produces ceramic tile. Quality decreasing is occurred on some Critical To Quality (CTQ) in a part of kiln. Kiln process itself was the last process and the most vital in determining final output of ceramic tile. Realizing the importance to the quality of kiln process, hence needed a problem solving method to improve and control process which taking place in Department Plant 3 so the amount ofdefect product can be minimized to achieve zero defect. The method to solve the problem is Six Sigma method that consist of Define, Measure, Analyze, Improve, and Control (DMAIC) phase. DMAIC phase begins with identifying customer needs to determine priority ofCTQ. Then measuring the sigma level, stability and process capability ofpriority CTQ. On the analyze phase, cause effect diagram is used to find failure cause analysis of CTQ, and then Failure Modes Effect Analysis (FMEA) tool is used to analyze the failure. On the final phase, improvement plan and process control act is done for company. The result ofthis research from Define phase is dash away as the priority ofCTQ. On the Measure phase known that sigma level in the month of January 2006 equal to 3,46 sigma and decrease to 3,24 sigma in Februari 2006. At that both period, process condition is not stable but capable enough if seen from Cp and Cpk value. On the Analyze phase is obtained the information that many factors like process or method, man, material, measurement, mother-nature, also machine and equipments are supposed causing instability and incapability of kiln process. Improve suggestions for managerial and technical side are given and Control suggestions to guarantee the quality of kiln process are also given on the Improve and Control phase.

TELKOM always make an effort to fulfill the society need upon products and services of fixed phon. The effort of TELKOM such as repair the old network (existing) and add the new network in certain area that have high potency of demand, such as in Gentan, Purbayan, Colomadu, Jaten and Kaliyoso. Those reparation and increament of the network give chances to customer of TELKOM who want to have a new installation of fixed phone (PSB). Process of PSB fixed phone in existing area is different with new network area. In new network area, TELKOM not yet had standard business process, and this is stimulate some problems, such as delayed activation, untidy network, lack of access of network and escalation (fatal cancel).Evaluation and improvement of business process are required in order to prevent and to reduce some problems. Evaluation and improvement of business process are conducted using the method of Fault Tree Analysis (FTA) and Malcolm Baldrige National Quality Award (MBNQA). Based on the result of FTA and MBNQA, there is improvement on business process new installation (PSB) of fixed phone in new network area by adding Drop Wire withdrawl in early stage.
