Abstract

Water is an important element that is a basic need for the survival of all living things. Currently, public awareness about the importance of good quality water is increasing. This is due to a wider understanding of the health impacts of unclean water. Water that is clean and safe to use not only has a positive impact on our health, but also on various aspects of daily life. Therefore, research on the quality and suitability of water for consumption is very important. The aim of this research is to determine the best method for comparing water quality for suitability for consumption. This research compares two machine learning methods, namely Random Forest and Artificial Neural Network (ANN) based on attributes for the suitability of drinking water, namely: PH, hardness, solids, chloramines, sulfate, conductivity, organic carbon, trihalomethanes, turbidity and potability. The research results show that the Random Forest algorithm has an accuracy rate of 67.823%, while the Artificial Neural Network (ANN) algorithm achieves an accuracy of 61.014%. From these results, it can be concluded that the Random Forest algorithm has higher accuracy compared to Artificial Neural Network (ANN).

Abstract

The Government of Central Java Province is committed to providing information and services to the public through its digital platform, the jatengprov.go.id website. This website is designed to make it easier for the public to access information about policies, programmes, and services offered by the provincial government. However, this website is experiencing some significant performance issues while trying to provide the best digital service. Some problems with the speed and efficiency of websites were found through tests conducted using Google PageSpeed Insights and GTmetrix. The website jatengprov.go.id received a score of 61, placing it in the middle category, according to a Google PageSpeed Insights desktop version test. However, the score dropped drastically on the mobile version, with a score of only 48, indicating poor performance on mobile devices. Although this website received a high score for SEO with a rating of 100, which indicates that it has been optimized for search engines, accessibility elements and best practices each received a score of 70 and 56. As a result of GTmetrix analysis, the website jatengprov.go.id received a "D" score with a performance score of 63% and a structural score of 62%. According to Web Vitals, Largest Contentful Paint (LCP) lasted 3.1 seconds, longer than recommended. However, the Total Blocking Time (TBT) and Cumulative Layout Shift (CLS) values are excellent, 0.0, respectively. This suggests that, although the page does not undergo much layout changes during loading, the time it takes to display the most important components still needs to be fixed. With this change, the website jatengprov.go.id is expected to improve the user experience and support the goal of the Government of Central Java Province to provide effective and efficient digital services to the public. Regularly tracking and improving website performance using tools like Google PageSpeed Insights and GTmetrix is vital.

Abstract

The solar system is one of the topics in natural science lessons taught in every school. However, school learning often relies solely on textbooks, which often do not explain the material in detail. This research aims to develop an Android-based application that utilizes augmented reality (AR) technology as a medium for introducing the solar system and to implement this AR technology. The method used in this research is the markerless method, which allows the development of AR without using special markers. This method is used to track objects in the real world and project them into the virtual world without requiring special markers. The research design uses UML (Unified Modeling Language), and the programming language used is C#. The result of this research is an Android-based solar system learning application. Based on the test results, the voice description is clearly audible, and the Star Tracking object can be detected well at a distance of 5 cm to 2 meters. Thus, it can be concluded that the markerless method can be implemented effectively.

Abstract

The purpose of this research is to design over the air programming mechanism for a node in wireless sensor network. Data are gathered from experiments of the proposed system on a constrainted environment. On this design, the Arduino that becomes the target of reprogramming has it’s bootloader modified to enable the capability to run embedded program from the SD Card. Arduino’s source code .ino file is compiled into a .hex file using the Arduino IDE. Then, it is processed using avrdude application into a ready to run firmware binary file on Arduino. A desktop application is made for this mechanism in order to control sender XBee device in transmitting data packet by packet. If the transmission was successful, the node will restart itself, and trigger the bootloader to load new program from the SD Card. The system is evaluated through preset scenarios which including testing at various distances and environments (indoor and outdoor). It was concluded that the reprogramming mechanism was uneffective in transmitting source code when at least one of the XBee devices is located inside the building which affected the transmission process. For the second testing scenario, both nodes were located outdoors with testing distance up to 15 metres, resulting with average transmission speed of 35 bytes per second for sent packet size of 60 bytes. The safest sent packet size to avoid packet loss while transmitting should not exceed 30 bytes for transmission distance up to 15 metres. Transmission speed across all test scenarios ranges between 14 bytes per second to 35 bytes per second. For indoor testing, the evaluation results showed that the designed OTAP mechanism in this study is not yet effective. This is assumed to be influenced by the transmission capability of the XBee communication module.
