Abstract

Bayi prematur membutuhkan kondisi inkubator yang stabil, sehingga pemantauan parameter vital seperti suhu, kelembapan, detak jantung, saturasi oksigen, dan intensitas cahaya perlu dilakukan secara real-time untuk mencegah risiko kesehatan. Penelitian ini mengembangkan sistem monitoring inkubator berbasis Internet of Things (IoT) menggunakan mikrokontroler ESP32 yang terhubung dengan sensor DHT22, MAX30100, dan LDR. Data yang diperoleh sensor dikirimkan secara nirkabel menuju aplikasi Blynk untuk memungkinkan pemantauan jarak jauh melalui smartphone. Hasil pengujian menunjukkan bahwa sistem mampu memberikan pembacaan suhu dengan error 0–1,64%, kelembapan 1,7–3,6%, detak jantung 0–1,6%, saturasi oksigen 0–1%, dan intensitas cahaya 0–3,7%. Waktu pengiriman data menuju Blynk berada pada kisaran 1,1–1,3 detik, tanpa ditemukan kegagalan pengiriman maupun gangguan koneksi selama pengujian berulang. Sistem juga berhasil memberikan notifikasi otomatis ketika parameter melampaui batas aman sesuai standar. Berdasarkan hasil tersebut, sistem monitoring inkubator bayi yang dikembangkan dapat bekerja secara akurat dan stabil, serta memenuhi kebutuhan pemantauan real-time pada prototipe inkubator bayi. Sistem ini dinilai layak digunakan sebagai perangkat pendukung yang meningkatkan kecepatan respons medis dan keamanan pemantauan inkubator.

Abstract

Arus awal pada saat motor induksi dijalankan dapat mencapai 5 – 7 kali arus nominal. Arus yang besar akan menghasilkan panas yang besar pula, panas ini dapat merusak motor itu sendiri dan tujuan penelitian ini agar dapat mencari metode pengasutan yang tepat untuk mengurangi arus start yang besar pada motor. Pengasutan pada motor induksi 3 fasa mempunyai beberapa metode yaitu Direct On Line (DOL), star-delta, auto trafo dan soft starter. Untuk dapat mengetahui arus start motor dapat menggunakan metode simulasi dengan software ETAP Power Station. Dari hasil simulasi yang dilakukan menggunakan ETAP didapatkan hasil sebagai berikut, untuk metode pengasutan direct on line (DOL) diperoleh arus start sebesar 2807,9 A atau 5,25 kali arus nominal dan voltage dip pada bus sebesar 14,88%. Untuk metode star-delta diperoleh arus start 1039,2 A atau 2,12 kali arus nominal dan voltage dip pada bus sebesar 5,51%.

Abstract

SMK Nasional Dawarblandong (SMK NADA) is a vocational school that focuses on developing technological skills; however, it still faces limitations in practical learning facilities, particularly in the field of Internet of Things (IoT). Preliminary observations showed that 78% of students had never used microcontroller devices and 85% had never used IoT simulation platforms such as Wokwi. This condition contributes to low levels of technical competence among students, while industry demand for IoT-related skills continues to increase. This community service program aimed to improve students' competencies through a training workshop on Wokwi simulation and the implementation of an IoT starter module using Arduino and ESP32. The training applied a participatory learning approach consisting of theoretical explanation, simulation practice, case studies, and direct hardware implementation. The evaluation was conducted using pre-test, post-test, and participant satisfaction questionnaires. The results indicated a significant improvement in students’ understanding of IoT concepts and automation systems. Questionnaire analysis showed that 36% of participants rated the clarity of tutor explanations with the highest score (score 5), indicating excellent communication effectiveness during training. Overall, the training successfully improved students' knowledge and practical skills in IoT simulation and microcontroller-based automation systems.

Abstract

The cooling process of granular products requires stable temperature control to maintain material quality. Conventional chiller systems with manual control tend to produce significant temperature fluctuations and operate less efficiently. This study proposes a Raspberry Pi-based chiller control system using the fuzzy logic method to improve temperature stability and enable real-time monitoring through the Internet of Things (IoT). The system utilizes the DS18B20 sensor for temperature measurement and the DHT22 sensor for humidity measurement, with a Peltier TEC1-12706 module serving as the cooling actuator and a blower fan functioning as the humidity controller. The fuzzy logic method is applied to determine the cooling performance level based on the measured temperature conditions. The test results indicate that the system is capable of regulating temperature adaptively, with a measurement error of ±0.89% for the DS18B20 temperature sensor and ±3.33% for the DHT22 humidity sensor. The actuators operate according to the detected conditions, where the Peltier TEC1-12706 functions at three levels (maximum, medium, and off), while the blower fan is activated when the humidity exceeds 70%. The implementation of this system demonstrates improved temperature stability and control effectiveness compared to conventional methods, making it suitable for application in small- to medium-scale granular product cooling systems.
