Quality of human resources faculty can be reflected from the implementation of productivity and quality Tridharma (education, research, community service and supporting field activities). Lecturer Workload and Evaluation of Higher Education Tridharma (BKD and the EPT-PT) aims to ensure the implementation of the faculty task runs according to the criteria set out in legislation. Data clustering Tridharma implementation is needed to get some knowledge of the pattern of Tridharma implementation at college. Clustering as a data mining technique should be scalable, reliable and meet an agreed standard. CRISP-DM is the standardization of data mining is used in this study. The results of data clustering found the pattern of proportion of Tridharma into 3 clusters representing patterns: professionals, managers and teachers.
This paper deals with the maintenance technique for industrial machinery using the artificial neural network so-called selforganizing map (SOM). The aim of this work is to develop intelligent maintenance system for machinery based on an alternative way, namely, thermal images instead of vibration signals. SOM is selected due to its simplicity and is categorized as an unsupervised algorithm. Following the SOM training, machine fault diagnostics is performed by using the pattern recognition technique of machine conditions. The data used in this work are thermal images and vibration signals, which were acquired from machine fault simulator (MFS). It is a reliable tool and is able to simulate several conditions of faulty machine such as unbalance, misalignment, looseness, and rolling element bearing faults (outer race, inner race, ball, and cage defects). Data acquisition were conducted simultaneously by infrared thermography camera and vibration sensors installed in the MFS. The experimental data are presented as thermal image and vibration signal in the time domain. Feature extraction was carried out to obtain salient features sensitive to machine conditions from thermal images and vibration signals. These features are then used to train the SOM for intelligent machine diagnostics process. The results show that SOM can perform intelligent fault diagnostics with plausible accuracies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
