Abstract

Information technology is now always experiencing a rapid increase in its use, one example is the website. Website is a collection of web pages, summarized in a domain, which is located in the World Wide Web (WWW) on the internet. This information media is useful in various fields, one of which is in agriculture. Where the information provided can help farmers in providing better results. One of the problems in agriculture that can be seen is related to the tropical climate in Indonesia. This greatly affects environmental conditions and can cause farmers to experience crop failure. One solution that can be done in this scope is with a plant factory. Where the plant factory is a technological concept that facilitates the formation of the right and good environment for plant growth, easy to control, does not require large land and is applied indoors. In its application, the plant factory still has shortcomings related to its information media. In this study, a monitoring website dashboard was designed to function as a medium of information on the plant factory. In system design, where the website is built using several components such as HTML, PHP, MySQL and Laravel Framework.

Abstract

Many documents were distributed on the Internet every day. Not all of the text in a document is important information. To seek information from documents that are widely used methods Information Retreival (IR). Research in the field of Information Retreival (IR) has been made since the 1950s. Document retrieval system is a system that can search for documents by keyword, but the retrieval of the document will encounter problems if they have to seek specific information from the document a polynomial with the number of constituent documents of text that amount is not small. Automatic Text Summarization combines two methods of graph method and the method of ant colony optimization and use features four sentences. Four features the phrase used, namely: the similarity between sentences, sentences that resembles the title of the document TF-ISF and TF-IDF. Tests performed include: testing the summary results of the system with the summary results of the manual to get the 76.3%, the test results summary system with the summary results Autosummary tools in Microsoft Word to get the 68.15% and the test results summary system with the summary results of the expert that high school teacher, getting the 78.43 %. Results compression rate to get the system summary 78.2%.

Abstract

Abstract—Public street lighting (LPJU) is a road infrastructure that is very important for road users at night. The constraints faced by User managers in an area in LPJU management are the problem of maintenance, monitoring, electricity consumption, and limited workforce. In an effort to overcome this problem, this study designed a tool in the LPJU system that can control LPJU ignition according to user needs by combining the timer and light sensor functions, and can monitor electricity consumption by calculating the power consumption or kWh meter and recording data on accumulation of electric power consumption every day at 06.00 WITA automatically stored on the micro SD Card. The accumulated data last recorded for 1 (one) month at the beginning of each month at 08.00 WITA will be sent using SMS services to users periodically. In addition, the user can monitor at any time with the "lapor" SMS format, the monitoring data sent in the form of the last electrical power consumption used by LPJU at that time.

Abstract

Electricity monitoring is making to determine the quality of electricity used. Currently, electricity monitoring is still done manually together with it requires a system that can measure the electrical parameters automatically. Therefore, an electrical monitoring system is designed for a three-phase system based on a wireless sensor network (WSN) using LoRa communication. The system consists of a transmitter node as a measured voltage, current, frequency, power factor, and active power using the PZEM-004T module. The receiver node is a gateway that receives data from the transmitter node used LoRa transmission and then forwards the data to be stored in a database using the internet network. The receiver node is equipped with backup data when the node receiver cannot be connected to the internet network. Finally, web monitoring is designed to make it easier for users to access electricity monitoring data online. Web monitoring will display data onto voltage, current, frequency, power factor in a single-phase system and active power in the form of the three-phase system into tables and graphs.

Abstract

Unbalanced intersectional traffic flow increases vehicle delays, fuel consumption, and pollution. This study investigates the application of deep reinforcement learning (DRL) to optimize traffic signal timing at the Pamelisan intersection in Denpasar, Indonesia. Real-world traffic data were incorporated into a SUMO microsimulation environment to train DRL agents using the deep Q-network (DQN) algorithm. Experimental results show that DRL-based optimization reduced the average vehicle waiting time from 594.49 seconds (static control) to 169.44 seconds and 173.10 seconds for agents trained without and with noise, respectively. The average vehicle speed remained stable at 5.6–5.97 m/s across all scenarios, indicating enhanced traffic efficiency without adverse effects. The findings underscore the effectiveness and adaptability of DRL in addressing traffic inefficiencies, optimizing them, and offering a robust solution for dynamic traffic management at unbalanced traffic intersections in urban areas.

Abstract

Learning Management System (LMS) is a system to manage learning and lecturer-student interaction. Udayana University has an LMS called OASE, which supports online and blended learning. OASE has some UI/UX issues such as login problem, rigid interface, and slow upload. UI/UX usage is important for website performance. UI/UX analysis involves Heuristic Evaluation and WEBUSE. Heuristic Evaluation focuses on appearance, while WEBUSE on user experience. OASE analysis with these methods aims to improve performance and measure UI/UX. This research aims to analyze the User Interface (UI) and User Experience (UX) of the OASE e-learning service at Udayana University Bali. The methods used in this research are Heuristic Evaluation and WebUSE to identify potential problems and assess user satisfaction in using the e-learning platform. The results of this evaluation will identify errors or problems that exist in layout, navigation, interaction, and other design aspects. Furthermore, a WEBUSE analysis was conducted by collecting data from users of the OASE e-learning service. The participants involved in this research are students and lecturers who have used OASE. The results of this research will provide a comprehensive picture of potential problems in the UI/UX of the OASE e-learning service at Udayana University Bali. The findings of the Heuristic Evaluation will serve as a guide for design improvements, while the WebUSE analysis will provide insights into user preferences for further improvements.
