Abstract

Hospital health services require effective communication tools between patients and nurses for patient comfort. Along with the development of wireless technology, many nurse call systems have been developed by researchers, application developers, and electronics activists to produce a more effective system and ease of use. The purpose of this study is to design a prototype of a wireless nurse caller system using NRF24L01 communication, and a keypad as a button that can be used by patients in the inpatient room to call patients, as well as an audio system in the nurse's room to receive calls from patients. By using the System Development Life Cycle (SDLC) method, the prototype of the nurse caller system was successfully realized and tested at the range and delay without obstacles and with obstacles. Based on the results of the distance and delay test in the unobstructed area, the caller node device and the call receiving node device can communicate at a distance of <100 meters with an average delay of 70.4 ms. Meanwhile, in the area where there is an obstacle (in the building), it shows the maximum communication ability between devices at a distance of 60 m with a delay of 74 ms and an average delay of 71 ms, Thus this prototype can be applied in hospitals.

Abstract

Robotic arms are one of the rapidly developing technologies in the field of robotics, with the need for efficient and reliable control systems. This research designed a robotic arm control system based on the ESP32 microcontroller with Bluetooth connectivity, using seven push buttons to control servo movements on four main components: shoulder, arm, gripper, and base. The purpose of the study is to analyze the performance of servo motion and the effectiveness of Bluetooth communication in controlling robot movement. The research method includes testing the response of servo movement at a certain angle range and evaluating Bluetooth communication capabilities at various distances and conditions. The results show that the servo motor has stable performance with minimal variation in movement time, with the average movement time varying between 1.64-6.82 seconds depending on the component. Bluetooth communication tests revealed 100% reliability at distances up to 15 meters without barriers, but decreased significantly to 40% at distances of 20 meters and only 10% at distances of 15 meters with barriers. The system features a 20x4 LCD for real-time monitoring and supports multiple control modes. This research contributes to the development of a robotic arm control system that is responsive and has potential applications in various industrial fields, with advanced recommendations to optimize Bluetooth communication range and quality.

Abstract

enelitian ini dilatar belakangi oleh aktifitas manusia yang memiliki hobi dalam memelihara ikan hias, maka dari itu kegiatan tersebut dimanfaatkan untuk membuat alat yang mampu mendeteksi kekeruhan air pada akuarium sebagai intputnya. Tujuan penelitian ini untuk merancang sistem kendali kualitas air dan filterasi air pada akuarium berbasis mikro kontroler untuk mendeteksi tingkat kekeruhan dan tingkat keasaman pada air akuarium dengan menggunakan sensor turbidity dan sensor pH. Adapun jumlah tingkat kekeruhan yang ditentukan yaitu 160 Nephelometric Turbidity Unit (NTU). Apabila kedua sensor ini dicelupkan kedalam air maka akan tampil pada LCD tingkat kekeruhan pada air dan pH pada air. Apabila tingkat kekeruhan yang di baca oleh sensor turbidity diatas 160 NTU maka pompa dan selenoid akan berfungsi untuk memindahkan air kedalam filterasi air sampai tingkat kekeruhan pada air sudah mencapai 160 NTU. Hasil penelitian menunjukkan bahwa kedua sensor dapat membaca tingkat kekeruhan nilai rata-rata eror 2,792% dengan tingkat akurasi pembacaan yaitu 97,208% dan keasaman pada air nilai rata-rata nilai eror 8,9% dengan nilai akurasi 91,1%. dan filter air pada akuarium mampu menjernihkan air sampai pembacaan sensor turbidity mencapai angka 160 NTU yang di tampilkan oleh LCD.

Abstract

Monitoring weather parameters in agricultural fields is essential for improving cultivation efficiency and supporting data-driven decision-making. Farmers often face limited access to real-time microclimate information, highlighting the need for an autonomous and accurate data acquisition system that can operate reliably in the field. This study aims to design and evaluate a sensor-based weather monitoring system that measures temperature, humidity, light intensity, and rainfall conditions, with an emphasis on supporting precision agriculture in rural areas. Field testing was carried out at the Paccoka agricultural site in Watang Suppa Village, where 15 sets of measurements were collected using digital sensors and an RTC module. The results indicate high sensor accuracy, achieving 97.92% for temperature, 94.03% for humidity, and 96.56% for light intensity, while the rain sensor consistently detected surface moisture variations based on incremental water droplets. The developed system demonstrated stable performance and effectively captured real-time microclimate dynamics, making it suitable for implementation as an IoT-based environmental monitoring solution in agricultural applications.

Abstract

The use of solar energy is increasingly important in addressing climate change. This study designed a real-time web-based solar panel performance monitoring system by monitoring voltage, temperature, and light intensity using Arduino Uno and ESP32 connected to Firebase. Testing was conducted for one day from 08.00-17.00 WITA. In the morning at 09.00, Panel 1 reached a maximum voltage of 22.43 V with a light intensity of 54,612.5 lux and a temperature of 38.4 ℃, while Panel 2 reached 21.67 V with an intensity of 54,612.5 lux and a temperature of 39 ℃, Entering the afternoon at 11.30, Panel 2 recorded the highest voltage of 22.82 V at an intensity of 54,612.5 lux and a temperature of 41 ℃, while Panel 1 showed a voltage of 22.6 V with the same light conditions and a temperature of 39.7 ℃. In the afternoon at 5:00 PM, both panels experienced a significant decrease, where Panel 1 dropped to 8.33 V with an intensity of 13,865 lux and a temperature of 28 ℃, while Panel 2 dropped to 8.45 V with an intensity of 10,918.3 lux and a temperature of 28 ℃. It can be concluded that high light is indeed important in producing electrical energy in solar panels but is not enough if it is not balanced with a relatively low temperature. Optimal conditions are achieved when maximum light is accompanied by a temperature that is not too high, with panel 2 showing slightly more stable performance than panel 1.
