Abstract

The arowana is a freshwater ornamental fish with high market value, requiring proper and meticulous care. One crucial factor in its maintenance is maintaining the water temperature within an optimal range of 26°C to 30°C. Deviations from this temperature range can cause stress in arowana fish, adversely affecting their health and growth. Therefore, a system for automatic and real-time temperature monitoring and control based on Internet of Things (IoT) technology is necessary. This research developed a Smart Monitoring System for Arowana Aquarium Temperature based on IoT, utilizing an ESP32 microcontroller and a DS18B20 temperature sensor, integrated with the Blynk application on Android devices. The system operates with automatic logic: when the water temperature drops below 26°C, the heater turns on; when it exceeds 30°C, the cooling fan is activated. If the temperature is within the 26–30°C range, both devices remain off. All temperature data is displayed in real-time on the Blynk application. The implementation results demonstrate that the system effectively maintains stable water temperatures within the desired range, reduces stress on the arowana, enhances maintenance efficiency, and provides convenience for the fish owner by enabling remote monitoring of the aquarium's conditions. Key words: Arowana fish, water temperature, Internet of Things, Blynk

Abstract

Security of electrical systems and CCTV constitutes a critical aspect in maintaining public safety, particularly amid rising theft cases exploiting infrastructure security gaps. This study aims toevaluate the ef ectiveness of the security system implemented by "Allefix" in protecting electricalinfrastructure and CCTV from theft threats. The methodology includes case studies, field surveys, face-to-face interviews, and descriptive statistical and thematic data analysis. The research findingsprovide a comprehensive overview of existing security system vulnerabilities and yield concreterecommendations for enhancing security ef ectiveness. These findings are expected to make asignificant contribution to the development of more comprehensive and sustainable security policies, particularly in the context of protecting critical infrastructure in Indonesia.

Abstract

Quail eggs are one type of food that is widely consumed by the Indonesian people. The design of an automatic quail egg peeler aims to help batagor traders who use quail eggs as one of the main ingredients. This tool is designed to increase the efficiency of the quail egg peeling process which has been done manually, is time-consuming, and requires a lot of energy, especially for elderly traders. This peeler is equipped with a counter technique that can automatically count the number of eggs that have been peeled, making it easier for traders to monitor daily production. The peeling mechanism involves breaking the shell and peeling the egg skin using a rotating roller. The sensor on this tool detects each egg that is successfully peeled and adds the number to the digital counter. The test results show that this tool can peel quail eggs with a high success rate and in a shorter time than the manual method. This automatic quail egg peeler is expected to be an efficient and practical solution for batagor traders, especially the elderly, to increase productivity and reduce workload.

Abstract

Flammable gas leaks such as Methane and Liquefied Petroleum Gas (LPG) pose serious risks of fire, explosion, and gas poisoning. This research develops a gas leak detection system based on the MQ-2 sensor, Wemos D1 microcontroller, and Internet of Things (IoT) technology. The system quickly and accurately detects gas leaks, provides automatic responses by shutting off gas flow via a solenoid valve, and activates a water nozzle valve for fire suppression. Real-time notifications are sent through the WhatsApp API. Testing showed response times of <5 seconds for gas leaks and <1 second for fires. The system is effective, real-time, and applicable in various environments

Abstract

Fires at solar-powered electric vehicle charging stations have the potential to cause significant losses, both in terms of material and human casualties. This research aims to design and implement an early fire detection system based on a DS18B20 temperature sensor and an MQ-2 smoke sensor integrated with an Arduino Uno. Temperature and smoke concentration data are monitored in real time, and if values above a threshold are detected, the system issues an alert via a buzzer and visual indicator. Test results indicate that the combination of the two sensors provides better detection accuracy than using a single sensor. This system can be implemented to improve safety at solar-powered electric vehicle charging facilities.
