Abstract

In the midst of this digital era, the rapid development of information technology, especially in the world of education, is very important for human needs in learning and teaching activities by utilizing this technology. One of them is by using various learning media such as android-based learning applications. Learning applications are programs that function as tools, materials or techniques used in teaching and learning activities with the intention that the process of educational communication interaction between teachers and students can take place effectively and efficiently. At SMK Taruna Terpadu 1 there are various problems, one of which is that teachers lack interactive learning media for their students, therefore the solution to the problem is to create an Android-based Japanese language learning application, with Android-based teachers and students can access it anywhere. Making this application using the javascript programming language, then SQLite as a local database, android studio as an android application development. Testing this application is done using the black box method by compiling a list of test cases and the white box method by compiling a flow graph. Blackbox testing is carried out to test whether the system developed is in accordance with what is stated in the functional system specificationsThe results of the application of this application are expected to help the learning process of teachers and students at the Taruna Terpadu 1 Vocational School.

Abstract

The rapid development of Internet of Things (IoT) technology provides significant opportunities for creating intelligent, efficient, and adaptive automation systems, especially for domestic applications. One of these implementations includes automated water storage management and remote control of household electrical devices such as lighting systems. This research aims to design and implement a web-based automatic water tank control and lighting management system utilizing the NodeMCU ESP8266 microcontroller and ultrasonic sensors (HC-SR04). The ultrasonic sensor accurately measures the real-time water level inside the tank. Meanwhile, NodeMCU ESP8266 functions as a central controller that processes sensor data and establishes Wi-Fi connectivity for communication with a web platform developed using the XAMPP server, PHP, and MySQL. The designed system employs a hybrid operation mode combining automatic pump control based on sensor readings and manual lighting control through a responsive web interface. The testing results demonstrate that the system operates with high accuracy, exhibiting a sensor measurement error of approximately ±2 cm and system response times of less than 1 second. Additionally, testing of the communication stability between NodeMCU and the web platform indicated reliable and consistent connectivity without significant interruptions. The developed system offers ease of management, effective energy and water efficiency, and aligns with an innovative, adaptive, and flexible smart living concept suitable for various scenarios in modern household environments.

Abstract

The large number of restaurant options in Depok City creates difficulties for users in selecting restaurants that match their personal preferences. This issue is further caused by the lack of a web-based recommendation system capable of systematically processing multiple selection criteria. This study aims to design and implement a web-based restaurant recommendation system using the Analytical Hierarchy Process (AHP) method and to analyze its application in determining criteria weights and restaurant recommendations. The AHP method is applied to evaluate price, distance, food quality, service, and atmosphere based on user preferences through pairwise comparisons. The system is developed using PHP and MySQL. System testing is conducted using black box testing, white box testing, and user response evaluation through questionnaires. The results indicate that the proposed system is able to generate objective and preference-based restaurant recommendations and effectively improve user experience in selecting restaurants in Depok City.
