Abstract

Spores are a breeding tool for ferns (Pteridophyta) which are generally found under the surface of each leaf. Research on the characteristics of Pteridophyta spores is generally done by observing their size and shape to see the type of spore. The method that will be carried out in this study requires a lot of understanding, experience, accuracy and time to achieve high accuracy in determining the type. Based on these reasons, it is necessary to develop another technique with modeling to help identify the type of Pteridophyta in the spore. This paper discusses image extraction for fern identification based on spore images using the Laplacian method and SVM. Laplacian method is used to extract features from spore images, while SVM is used to classify ferns. This method requires a lot of understanding, experience, accuracy and time to achieve high accuracy in determining the type. Based on these reasons, it is necessary to develop another technique with modeling to help identify the type of Pteridophyta in the spore. The purpose of this research is to make Support Vector Machine (SVM) modeling to identify fern species based on spore images in Eigen space. The data used are spore images with four classes, each of which has 24 data per class with a total of 96 images. The method used in this research is Laplacian method for feature extraction and SVM for data classification using Gaussian RBF and Polynomial kernel function experiments. The result of this research is the accuracy of each extraction that has been tried. The best result lies in the RBF kernel function with 70% feature extraction and 10 parameters with an accuracy of 98.96%.

Abstract

The purpose of this study was to determine the direct effect of Job Satisfaction on Organizational Citizenship Behavior (OCB) and the indirect effect of Job Satisfaction on OCB through the mediation of Transformational Leadership and Interpersonal Communication. Job Satisfaction as the independent variable, the variables of Transformational Leadership and Job Satisfaction as the mediating variable, and OCB as the dependent variable. The research sample involved was from 266 teachers who were selected by proportional random sampling from 20 junior high schools in the city of Bogor, West Java. This research uses Path analysis technique with PLS-SEM Program. This research concludes that: (1) Job Satisfaction has a significant positive direct effect on OCB ( = 0.358 p < 0.01), (2) Job Satisfaction has a significant positive effect on Transformational Leadership ( = 0.755 p < 0.01), (3) Job Satisfaction has a significant positive effect on Interpersonal Communication ( = 0.941 p < 0.01), (4) Transformational Leadership has a significant positive effect on OCB ( = 0.185 p < 0.05), (5) Interpersonal Communication has a significant positive effect on OCB ( = 0.337 p < 0.01), (6) Job satisfaction has a significant positive effect on OCB through the mediation of Transformational Leadership ( = 0.140 p < 0.05), (7) Job Satisfaction has a significant positive effect on OCB through the mediation of Interpersonal Communication ( = 0.317 p < 0.01). Based on the conclusions of the research results above, the strengthening of OCB can be carried out directly through increasing job satisfaction and can be done indirectly through increasing job satisfaction through the mediation of interpersonal communication.
