Abstract

Serial Peripheral Interface (SPI) is a synchronous serial communication whose data or signal transmission involves Chip Select (CS) or Slave Select (SS) pins, Serial Clock (SCK), Master Out Slave In (MOSI), and Master In Slave Out (MISO). In the Arduino Uno, there are four pins that allow Arduino Uno to perform SPI communication. In this research, SPI communication is implemented to expand the output of the Arduino Uno by using the features of the MCP23S17 IC so that the Arduino Uno, which initially has 20 output pins, can expand to 36 output pins.The results of the research show that the Arduino Uno manages to control 36 output pins. 16 output pins from the MCP23S17, 16 output pins from the Arduino Uno, and 4 pins are used for the SPI communication line. The results of this study also show the form of the SPI communication signal from Arduino Uno in declaring 21 registers on MCP23S17, declaring the MCP23S17 pin register as output, and implementing the output using LEDs.

Abstract

Pada penelitian ini bertujuan untuk mendapatkan gambaran bahwa alumni jika setelah lulus akan mendapatkan pekerjaan sampai seberapa lama menunggu, sehingga dalam penelitian ini mendapatkan data berapa lama alumni mendapatkan pekerjaan. Dengan demikian peneliti dapat mendeskripsikan penilaian terhadap alumni pada masalah penyelenggaraan dan mutu layanan program yang berada di Program Studi S1 Teknik Elektro Fakultas Teknik Unesa dan dapat mendeskripsikan terhadap penilaian pengguna alumni pada kompetensi lulusan Teknik Elektro FT Unesa. Metode sampling dengan cara random. Jenis data yang dikumpulkan dalam penelitian ini adalah data primer yang diperoleh langsung dari alumni dan pengguna alumni melalui kuesioner yang terstruktur. Penyebaran kuesioner dilakukan secara online melalui Google form dan penyebaran secara langsung kepada alumni atau pengguna alumni yang diketahui dengan jelas keberadaannya. Pengumpulan data lapangan diperkirakan akan dimulai pada Mei 2020 hingga Agustus 2020. Adapun hasil penelitian menunjukkan sebagian besar alumni Program Studi S1 Teknik Elektro Fakultas Teknik Universitas Negeri Surabaya. Terdapat 5,60% alumni melamar ke perusahaan tanpa mengetahui lowongan yang ada, 11,01% alumni mendatangi pameran kerja. 20,15% alumnimencarikerjalewat online, 3,36% alumni mencari kerja dengan menghubungi perusahaan, 0,75% alumni yang menghubungi Kemenakertrans dan ada 0,37% alumni yang menghubungi agen tenaga kerja komersial/swasta. Jumlah alumni yang memeroleh pekerjaan sebelum lulus sebesar 39,3%, yang memeroleh pekerjaan pertama setelah lulus sebesar 45%, dapat pekerjaan setelah lulus 118 alumni, 4% tidak memerlukan Pendidikan tinggi, memerlukan pendidikan setingkat lebih rendah sebesar 7,43%, memerlukan pendidikan setingkat lebih tinggi sebesar 13,71%, dan memerlukan tingkat pendidikan yang sama sebesar 74,86%.

Abstract

Magnetic Balance testing on three-phase transformers that are still done manually has the potential to cause human error and delays in defect identification. This research aims to develop an automatic Magnetic Balance testing tool based on the Internet of Things (IoT) using Arduino Mega 2560 microcontroller and Wemos D1 mini (ESP8266) connected to Google Spreadsheet as an online data logger. Voltage regulation on each phase is done automatically through a relay, while the measurement results are displayed on the LCD and recorded in real-time to the Spreadsheet. Based on the test results, the device functions properly and meets the Magnetic Balance testing standards, this is evidenced when we test one of the phases, the voltage value read in the other two phases when summed is close to or in accordance with the phase that is given a voltage. The successful integration of the system with Spreadsheet allows remote monitoring of test results and supports early detection of potential transformer damage. Keywords: Arduino Mega 2560, Google Spreadsheet, Internet of Things, Magnetic Balance, Wemos D1 mini ESP8266.

Abstract

Dragon fruit is a high-value commodity that has gained increasing popularity in the global market, yet requires intensive care, particularly in terms of precise watering and lighting management. In Indonesia, dragon fruit cultivation often faces challenges due to reliance on imprecise manual systems. Conventional systems currently available are frequently inefficient as they cannot dynamically adapt to fluctuating environmental conditions. Therefore, this research aims to develop an IoT-based automation system capable of optimizing dragon fruit growth through intelligent watering and lighting control using more adaptive fuzzy logic methods. The system is designed with an ESP32 microcontroller as the control center, integrated with a YL-69 soil moisture sensor and LDR light sensor. Both sensors were calibrated with high accuracy, showing errors of 2.85% for the moisture sensor and 2.80% for the light sensor respectively. Sensor data is then processed using fuzzy logic to generate proportional control through PWM modulation for water pump and LED light actuators. System implementation demonstrates robust performance, where lights turn on fully at light intensity ≤110 lux, dim at 110-640 lux, and turn off above 640 lux. Meanwhile, the pump operates at maximum capacity when soil moisture ≤45%, at half power between 45-70%, and stops above 70%. The Blynk platform is utilized for real-time environmental monitoring through a user-friendly mobile interface. Twenty-four hours test showed that the system is responsive and adaptive, and has the potential to increase water and energy efficiency compared to conventional systems.

Abstract

This research presents the design and development of an Internet of Things (IoT)-based Smart Door Lock system implemented in a sterilization room with a step-by-step locking mechanism. The system is designed to improve security and ensure that sterilization procedures are carried out according to standards, where doors can only be accessed sequentially as predetermined. The hardware consists of an ESP32 microcontroller connected to a fingerprint sensor for user authentication and a solenoid door lock as the door actuator. The system is also integrated with an IoT-based server, enabling real-time monitoring of door status through a mobile application. Experimental results show that the system functions properly, allowing doors to open only according to the specified sequence, while access data can be stored and monitored online. Therefore, this Smart Door Lock system provides an effective solution to support both security and operational efficiency in sterilization rooms. Keywords: Smart Door Lock, IoT, ESP32, sterilization room, step-by-step locking.
