Abstract

Historical manuscripts are one of documents that important to be preserved because they contain a lot of information, one example of them is script as the historical documents . Historical document mostly still use handwriting in so many reserch. Currently, there are many research regarding the preservation of characters. One way of preservation that can be used is the digitization process. Digitizing’s process tanable by recognizing existing information using technology. The technology that can be used is machine learning. Handwriting is a complex case because of the many variations of these characters and the output of the author where variations of the author will produce different writings. The relevant fields for text and documents are Optical Chacarter Recognition (OCR) and handwriting recognition. There are several methods that can be used in the machine learning process, including Artificial Neural Network (ANN) and Convolutional Neural Network (CNN). Both of these methods are methods that can accept complex image input to be processed and recognized, therefore this method is highly recommended for processing handwriting.

Abstract

Subak is a group of farmers in Bali to manage rice fields irrigation. Farmers come directly to the rice fields which need time to monitor their fields irrigation so that it’s less efficient. Based on this, an Android-based subak irrigation monitoring application was designed using the flutter framework with subak culture system for monitoring farmers fields irrigation and using supporting application namely Android Studio. The result of this research is an Android application that can display the location of the rice fields that registered, successfully sends a high water request, successfully sends a request for registration of subak fields, and successfully reports damages in case of damages to the fields and also successfully retrieves data on the condition of rice fields whose data is taken from the Antares database. The Black-box testing and System usability scale (SUS) used in the Android application has been successfully run according to the given scenario and functions and also suitable for use by users because the result of SUS are above the average value that is 72.875.

Abstract

Subak is a traditional organization owned by the Balinese people to manage rice field irrigation. In the process of irrigating the fields, subak administrators and farmers check the condition of the irrigation in the fields by directly coming to the location to check the condition of the water level in the fields, so it is time consuming and less efficient. The creation of a geographic information system is intended so that subak administrators and farmers know the water level of the fields and regulate irrigation without going to the fields. The geographic information system is built using the Laravel framework equipped with a map. The map was created with the Google Maps API with the aim of displaying the location of rice fields. The result of this research is a geographic information system that can monitor the height of rice fields and display data on a map. The information system can also receive sensor data and send configuration data to Antares. In black box testing, the information system has been running according to the functions and scenarios given. Based on the results of the System Usability Scale test, the application obtained a score of 76,125 which indicates the application is classified as good and can be accepted by the user.

Abstract

Some studies such as Aoki measure clock skew by filtering outliers by selecting the minimum offset that is collected using linear regression to calculate the slope of the accumulated minimum offset. Huang who uses the QPM (Quick Piecewise Minimum) algorithm to calculate the skew of the minimum offset at the beginning and end of the collected offsets and Moon's research that uses the LPA (Linear Programming Algorithm) algorithm which determines the clock skew of the line gradient that is below the offset. In addition, there are several methods that have the potential to be used in measuring clock skew including ant colony, bee colony, particle swarm, and also genetic algorithm. From these several methods, one method that has potential as a method that can be used for measuring clock skew will be selected. The method that can be used is particle swarm optimization because it is considered more efficient and flexible and easy to implement with few parameters used.
