The surface roughness of a machining process is a very important factor in the field of production that is one of the turn-milling process. Turn-milling is a combined machining process of turning and milling with complete tools (cutting) where workpieces and tools rotate together. The turn-milling process can be classified in orthogonal turn-milling, tangential turn-milling and co-axial turn-milling. The resulting surface surface quality is also affected by the parameters of the machining process in the form of rotation of the workpiece and the rotation of the tool. The purpose of this research is to know the effect of parameters on surface roughness and optimal Parameter to surface roughness by doing tangential process of turn-milling. By varying the parameter variables, the surface roughness generated in this study is influenced by the rotation of the workpiece and the rotation of the tool. The higher the tool rotation the lower the surface roughness. As well as the rotation of the workpiece the higher the rotation of the workpiece the finer the surface results. The optimal parameter is a rotation tool -2500 rpm with a rotation of 1000 rpm objects found in the roughness class N6 with a roughness value of 1.282 μm where the roughness value is lower than the other roughness values.Keywords: Turn-Milling, Tangential Turn-Milling, Rotation, Surface Roughnees

This paper aims to compare between method of AHP (Analytical Hierarchy Process) and fuzzy AHP to evaluate the OEE values on screw press machine in PTPN V Sei. Pagar. The analyzing of criteria and sub-criteria in the hierarchy model to rank alternative selection actions to minimize the screw press machines losses was done in this paper. Two critical losses occurring in the screw press machine were setup and adjustment losses, and equipment failure losses. The result showed for the AHP method, the most influential criteria for setup and adjustment losses were workers with a value of 0.567 and the highest alternative value of action for periodic checking. The equipment failure losses were obtained the most influential criteria of the machine with a value of 0.444 and the best alternative selection action that was the human resources development. For Fuzzy AHP method of setup and adjustment loss, the most influential criteria was workers with value of 0.555, and best alternative action was periodic checking. Equipment failure loss was obtained the most influential criteria for machines with a value of 0.444 and the best alternative selection action was the human resource development. From the comparison of both methods, it can be concluded that the AHP method was more simple in terms of data processing. However, the fuzzy AHP method was revealed more accurate values due to not containing subjective judgment in terms of selection action to improve the effectiveness of the screw press machine.Keywords :OEE, AHP, Fuzzy AHP, Screw Press

One of the most commonly used geospatial mapping methods is photogrammetry (aerial mapping). Photogrammetry is a method of mapping objects on the surface of the earth by using aerial photography as a medium. The aerial mapping process is carried out through cameras installed on Unmanned Aerial Vehicle (UAV). From the aerial photography, object interpretation and geometry measurements will be carried out to produce line maps, digital maps and photo maps. In general, photogrammetry is a mapping technology by utilizing aerial photography to be processed into a geo-spatial information system. Batu Bersurat Village is one of the villages located in Subdistrict XIII Koto Kampar, Kampar Regency, which did not have a geospatial information map. Community service team from the Mechanical Engineering Department of the University of Riau had a plan to carry out community service activities in Batu Besurat Village in the form of making geospatial information maps through aerial mapping. This aerial mapping activity was carried out by utilizing UAV with the type of fixed wing. In its implementation, the community service activities were planned to involve Mechanical Engineering students, university students of the University of Riau, village officials and the local community. It is expected that with this community service program, the geospatial information system map made by Batu Bersurat Village can be used in village spatial planning for agricultural land, residential land and validation of village boundaries.
