Rapid Fabrication

In 21th century, the product upgrading becomes faster and faster. The development of varieties of production needs rapid manufacturing technology. The rapid fabrication of sand mold & core is the key of rapid casting. In this paper, the rapid manufacturing technology without pattern was applied to produce the complicated sand molds & cores of pump case. The digital precision forming technology without pattern casting was selected to mill the outer sand mold. And the Selective Laser Sintering (SLS) technology was used to print the sand core. So the complicated sand molds and cores were fabricated rapidly without pattern. As a typical digital manufacturing technology, the rapid manufacturing technology without pattern has a variety of benefits such as short cycle, low cost, flexibility and so on. The technology that combines the sand milling and SLS provides a high-efficiency method for the Single and small batch castings.

Knowledge of animal feed and waste is an important component in building the livestock industry. The aspectof availability of feed and the production of livestock waste is one of the problems by cattle farmers in MattirowalieVillage, Libureng Sub-District, Bone Regency. Efforts to increase the capacity of farmers in solving these problems areneeded to increase the productivity of their livestock. This program aims to increase knowledge for farmers of beef cattlein processing agricultural and livestock waste into feed products and processing them into organic fertilizer. This activityis an implementation of the Program Pengabdian Kepada Masyarakat Unhas (PPMU) Program Kemitraan Masyarakat(PKM). This activity was carried out in Mattirowalie Village, Libureng Sub-District, Bone Regency. The partner groupsinvolved as targets were the "Kurusumange" and "Masempo Dalle" farmers group (FG). The number of trainingparticipants involved in this activity is approximately 25 peoples, overall were cattle farmers with 2-3 cattle/person. Theimplementation of technology introduction programs was carried out in the form of training programs and technologyassistance. Several technology packages that have been implemented were: 1) ammoniation technology, 2) complete feedsilage fermentation technology, 3) manufacturing of local microorganism (LM) technology and 4) Urea Molasses Block(UMB) manufacturing technology. The results of the implementation of activities to increase the capacity of partnermembers in processing agricultural waste and livestock into alternative animal feed and organic fertilizer
