Pure water was consumed and insufficient that causes from the population continuous increasing. The water was contaminated with some pollutants. The most of science laboratory produced only the distillation water for experimental learning. In present distillation technology was released a lot of wastewater. Therefore a research group interested in applies to use value engineering for water resource management. This research collected the data analysis of distillation water process and designed of renewable wastewater for cooling process. The results shown that before improve system a distillation water and wastewater were found 3.7 l/h and 140.3 l/h respectively. For after improve system a distillation water was found only 3.82 l/h and without wastewater. Furthermore economical study found that the cost of water and electric were saved 394.23 bath/month when compared with old system. And the payback period was 114.16 month (9 years 6 months 3 days). Hence the applied value engineering for water resource management could be saved wastewater 100 percent.

This research is the study for effected of orientation setup workpiece from Rapid Prototyping process. The objective of this study has to minimize average tolerances of specimen size and roundness of cylindrical specimen. Specimens were studied with orientation direction define 3 axis (X Y Z) and created by rapid prototyping Machine with FDM Technology. The Measuring average tolerance of specimen size and roundness of cylindrical specimen used the Coordinate Measuring Machine (CMM). The Result showed that test specimens were formed along the X axis having lowest of average tolerances. The increasing average tolerances of diameter depend on the increasing diameter size. The roundness value of cylindrical surface forming the X axis was the most circular cylinder. The roundness value of cylindrical was depend on the increasing of diameter size. It shows that when the workpiece has a larger diameter. The workpiece would be circular cylinder is decrease
