Published: April 2020

Abstract
Complementary and Alternative Medicine (CAM) therapy is quite popular for chronic diseases such as diabetes, arthritis, and others. CAM has become very popular in the last period. One area of CAM is iridology, which is an alternative diagnosis that links iris patterns, color, tissue weakness, damage and other characteristics, which can obtain evidence about the patient’s systemic health. In identification based on the eye image, it requires an iris separation process. This separation process in image processing is done by segmentation. So that segmentation plays an important role in the identification of diseases based on images. In this research segmentation is done by combining the Hough Transform method and the clustering-based segmentation method, the Fuzzy C-Means method. The segmentation is done on the iris object which is sourced from UBIRIS V2 database. System evaluation is done by measuring accuracy, sensitivity, specificity and execution time. Test results on the tested iris image indicate the proposed method is able to segment the iris image properly.

Authors: Sapoetra Jimmy 
Published: April 2020

Abstract
Local content is one way to promote local wisdom in a country. Indonesia, being a very big and plural country, has a tremendous local wisdom that can promote the country in many aspects: political, economic, cultural, and in the educational sector. One of the main issues in the local wisdom is the local content. This research is trying to investigate the local content found in the reading passages in the local English textbooks used in Indonesian high schools. The research shows that many local English textbooks do not include local content in their reading passages. The problem arises due to the fact that many authors and or publishers are not aware of the importance of such local wisdom in their textbook writing. Another problem is due to the hegemony of so called the ideology of political identity within one nation which affects the philosophy of textbook writing in the respected country. By doing the research, it is hoped that many Indonesian authors write the reading passages which promote the local content in order to highlight the local wisdom of the country to other countries in the world.
