Abstract

Smoking is one of causes disease which especially on respiratory tract because the cigarette were content that is not good for body. Passive smoker is really made a loss for smoke/vapor that they inhaled. So therefore, smoke detector was created by using connection of WiFi that connected to ESP32 which sending data of detection  from MQ-2 sensor (detect content’s smoke of tobacco cigarette) and Adafruit sensor (detect content’s vapor of e-cigarette) to firebase that integrated by android software. This would faciliated for hotel firm because the hardware not only detect smoke of cigarette, but also vapor of vape will detected so guest that disobey the rules who using except cigarette will be fined which will be monitored by hotel’s employee remotely via android software. System of this hardware specifically only for once detected which if it detected, then green LED changed to yellow (e-cigarette) if the amount shows ≥ 25 ppm and/or red (tobacco cigarette) ) if the amount shows ≥ 0.05 ppm which followed by sound of buzzer and DC fan that will dispensed smoke/vapor out of room. Neutral room which was tested for 10 minutes produced a maximum of 0.03 ppm amount of detected smoke and 24 ppm amount of detected vapor. In the MQ-2 sensor experiment with a level of 1 burst it produces 0.42 ppm and delay of 2 seconds for the sensor to detect, in a room with a volume of 1050 m3 it returns clean with a delay of 11 seconds with amount of 0.04 ppm. In the Adafruit sensor experiment with a concentration of 1 burst it produces 33 ppm, a delay of 2 seconds for the sensor to detect, in a room with a volume of 1050 m3 it returns clean with a delay of 8 seconds with amount of 24 ppm.

Abstract

Gardening is an activity widely practiced for the preservation of plants or simply as a hobby. However, gardening is still quite challenging for many people due to limited available land. Apart from land constraints, another inhibiting factor is the reliance on manual tasks, such as the watering process. Therefore, one solution that can be implemented is to create a miniature garden with a system that can control and monitor Soil Moisture, temperature, air humidity, and light intensity. The smart garden miniature system utilizes Arduino IDE software, an ESP32 module as the microcontroller, Soil Moisture sensors, DHT-22 sensors, an L298N motor driver to operate the water pump and exhaust fan, and relays connected to LED strips. This system is connected to an Internet of Things-based Android application. The results show that the control and monitoring system operates effectively, in line with the predetermined design.

Abstract

Pengelolaan daya listrik di kamar kos sering kali menimbulkan ketidakadilan karena biaya listrik disamaratakan, meski pemakaian berbeda. Untuk mengatasi masalah ini, dirancang sebuah sistem pemantauan daya listrik dengan teknologi LoRa. Sistem ini memanfaatkan mikrokontroler ESP32, sensor PZEM-004T, LoRa, dan Arduino IDE. Data penggunaan daya listrik yang dikumpulkan oleh sensor dikirim ke pemilik kos melalui jaringan LoRa. Data penggunaan daya listrik dikirim melalui jaringan LoRa hingga 150 meter (RSSI -107 dBm) dalam kondisi NON-LOS dan 600 meter (RSSI -111 dBm) dalam kondisi LOS, kemudian diintegrasikan ke aplikasi Android untuk pengelolaan dan pemantauan daya listrik. Hasil pengujian menunjukkan akurasi 99%, menjadikan sistem ini solusi efektif dan efisien untuk pengelolaan daya listrik di kamar kos.   Abstract Electricity management in boarding rooms is often unfair because electricity costs are shared equally, even though each room uses different amounts of electricity. To address this issue, an electricity monitoring system was developed using LoRa technology. The system uses an ESP32 microcontroller, a PZEM-004T sensor, LoRa, and Arduino IDE. The sensor collects electricity usage data and sends it to the landlord via the LoRa network. This data can be transmitted up to 150 meters (RSSI -107 dBm) in NON-LOS conditions and 600 meters (RSSI -111 dBm) in LOS conditions. The system is also integrated with an Android application for easier management and monitoring. Testing results show an accuracy of 99%, making this system an effective and efficient solution for managing electricity in boarding rooms.

Abstract

Fertilizer plays a crucial role in maintaining soil fertility and supporting optimal plant growth. However, fertilizer quality monitoring in previous studies has generally been conducted partially using separate tools and has not been integrated with an application-based real-time monitoring system, resulting in inefficiency and poor decision-making. This study aims to design and implement an integrated Android-based fertilizer quality monitoring system for planting media. The methods used include hardware design using a 7-in-1 soil sensor and an ESP32 microcontroller, Android-based software development, and data integration using the Firebase Realtime Database for real-time communication. System testing was conducted by measuring temperature, humidity, pH, and the content of Nitrogen (N), Phosphorus (P), and Potassium (K) in the planting media. The test results show that this system is capable of measuring parameters with a temperature value of 26.2°-28.7°C, humidity 25.3-29.1%, pH 6.2-7.1, nitrogen 107-250 ppm, phosphorus 280-478 ppm, and potassium 265-492 ppm in real-time. In addition, this system is equipped with an automatic fertilizer condition classification feature as well as plant recommendations and care suggestions. The main contribution of this research is the development of an Android-based fertilizer quality monitoring system that is integrated, real-time, and capable of increasing monitoring efficiency and supporting decision-making in sustainable planting media management.
