Abstract

Batik is an important part of Indonesia’s cultural heritage, with each region producing unique designs. In Central Java, Semarang is known for its distinctive batik patterns that reflect rich local traditions. However, many people are still unfamiliar with these designs, which threatens their preservation. This study develops an automated system to classify Semarang batik patterns, showing how technology can help safeguard cultural heritage. A convolutional neural network (CNN) approach was used to recognize ten batik types, including Asem Arang, Asem Sinom, Asem Warak, Blekok, Blekok Warak, Gambang Semarangan, and Kembang Sepatu. Pre-processing steps—such as image resizing, cropping, flipping, and rotation—improved model performance and reduced complexity. Five CNN architectures (MobileNetV2, ResNet-50, DenseNet-121, VGG-16, and EfficientNetB4) were tested using 224×224 input size, Adam optimizer, ReLU activation, and categorical cross-entropy loss. Results show VGG-16, ResNet-50, and DenseNet-121 achieved perfect accuracy (1.0) on a dataset of 3,000 locally collected images. These findings highlight CNN models’ strong potential for batik pattern recognition, supporting digital preservation of Indonesian culture.

Abstract

creatures which is very important in a everyday, therefore ensuring that there is always water available in the reservoir is very important. However, in the process of controlling and monitoring water in the reservoir there are several problems, for example the location of the reservoir is on the top floor of the building and access is too difficult for monitoring the water reservoir. By designing a water pump control system with NodeMCU ESP 8266 using a Telegram communication-based monitoring system, system design using research and development methods can provide solutions and resolve existing problems. Via Smartphone, computer or laptop you can control water pumps and monitor water levels based on Telegram communication anytime and anywhere with Internet of Things (IoT) technology. Using an ultrasonic sensor type HC-SR04 to detect the water level in the reservoir, the process with the NodeMCU ESP 8266 board can be controlled and monitored using the Telegram massager application. The design has been carried out to test the function of every aspect of the components used, such as manual control, automatic systems, results read by ultrasonic sensors, Telegram communications and Telegram notifications that can run and optimally.

Abstract

Modern agriculture faces increasingly complex challenges that demand innovative technological solutions to improve efficiency, precision, and sustainability. The Internet of Things (IoT) offers significant potential for agricultural automation, particularly in hydroponic cultivation systems. This study presents the design and development of an IoT-based automatic nutrient control and monitoring system for vertical hydroponics. The system utilizes an ESP32 microcontroller to regulate the distribution of nutrient solutions enriched with essential macro- and micronutrients. Nutrient concentration is measured as Total Dissolved Solids (TDS) and monitored in real time through the Blynk mobile application. Users can operate the system in either automatic or manual mode. Experimental results show that the developed prototype achieves high accuracy in TDS measurement, with an average accuracy of 97.38%, and effectively maintains nutrient concentration within the desired range. The proposed system demonstrates reliable control performance and contributes to enhancing nutrient delivery precision, productivity, and land-use efficiency in modern smart farming practices.

Abstract

There are various occasions where data taken from field measurements need to be stored remotely, but yet accessible from many places and by any means. The emergence of online data storage for documents such as Google Docs had made it possible to build a system that acquires data from sensors and stores them as an online document accessible anywhere. The purpose of this research is to develop a system prototype to store and display data from the result of measurements toGoogle Sheets through the use of ATmega16A microcontroller system and a server application. The proposed system consists of a data acquisition unit, a PC that acts as a server and web services. The data acquisition unit is made up from an ATmega16A microcontroller, LM35 astemperature sensor, photoresistor for light intensity measurement and FT232RL module for serial communication. Application server that runs on a PC is written in Processing programming language.The web services being used are Temboo and Google Sheets. From the test results it can be concluded that data acquisition unit had been able to transmit data to PC via serial communication, the server application was successfully built in terms of interface design and functionalities and a table in Google Sheets had been capable to store measurement results and display them correctly. In order to deliver a sense of real-time measurement, it is advisable to add a real-time clock chip module to microcontroller system such that the momentthe data arrive from sensors is recorded. The server application can be improved by the addition of local data logging feature to anticipate the loss of data caused by disturbances during onlinetransmission.

Abstract

This study aims to optimize the use of an optocoupler sensor in an Arduino Nano–based ocean current velocity measurement device that is simple, cost-effective, and sufficiently accurate. The measurement system employs a propeller mechanism driven by ocean currents, where the optocoupler sensor detects rotational pulses and the Arduino Nano processes the data to calculate current velocity. The research methodology includes hardware design, software development, and performance evaluation. A comparative testing method was conducted by comparing the measurement results of the developed device with those obtained from a standard ocean current measurement instrument as a reference. Initial test results indicated measurement deviations with an average error of 13.54%, influenced by technical factors such as sensor orientation relative to flow direction, water depth, current turbulence, and data acquisition delay.

Abstract

An Augmented Reality (AR)-based learning application was developed as an interactive visual medium to introduce animal classification to early childhood learners. The application uses flashcards scanned with a device camera to display three-dimensional (3D) objects in real time. This study aims to design and build an AR-based mobile application using Unity and Vuforia as an engaging self-learning tool. Development followed the Multimedia Development Life Cycle (MDLC), comprising concept, design, material collection, assembly, testing, and distribution. Functional black-box testing across 12 scenarios showed a 100% success rate, with all features operating as designed, including menu navigation, marker scanning, and 3D object visualization. Preliminary observations indicated that the visualization increased children's interest and involvement during learning, although this effect has not yet been measured with a validated evaluation instrument. Therefore, the application is considered a practical interactive medium for introducing animal classification based on feeding type - carnivores, herbivores, and omnivores - to young children.

Abstract

Residential lighting and curtains are commonly controlled independently, limiting daylight utilization and increasing reliance on electric lighting. This study developed SOLART, an ESP32-based local embedded system that integrates automatic lamp switching and curtain actuation using ambient light intensity as the control variable. The prototype employed an LDR-LM393 module, a one-channel relay for a 5 W AC lamp, and a BTS7960 motor driver connected to a DC motor. A rule-based threshold of 100 lx was implemented in Arduino IDE with a two-second sampling interval. Functional and electrical tests were conducted on the controller, sensor, relay, motor driver, motor, and lamp. At 70 lx, the system switched the lamp on and closed the curtain; at 220 lx, it switched the lamp off and opened the curtain. The sensor estimates differed from lux-meter readings by 1.43% and 0.45%, respectively. Relay and motor measurements generally showed deviations below 6%. A 19.39% deviation in the BTS7960 control-voltage reading was attributed to the limitation of measuring a switching or PWM signal with a handheld multimeter and therefore requires oscilloscope verification. The results demonstrate functionally consistent dual-actuator local control without internet dependence, although broader calibration, response-time measurement, and long-term energy testing remain necessary.
