“…The measured distance is obtained from the initial time of sending the ultrasonic signal until it is received at the echo pin, then multiplied by the speed of sound (340m/s) and finally divided by 2 [20]. The distance that can be measured with this sensor is 2cm to 4m [21]. In this study, the HC-SR04 ultrasonic sensor was placed on the wall in the room near the entrance.…”

This research aims to create a system that can monitor server room security by utilizing IoT technology, controllers, sensors, actuators, and Telegram API. The system made includes security for the indoor and outdoor parts. The method used in this study is experimental. The output obtained by the user is telegram text messages, photos, and video. The main controller on this system is the Raspberry Pi. This study showed that if the server room temperature is >230C, the system will send a message via Telegram. If the PIR sensor_1 or PIR sensor_2 detects an intruder or the measured distance is <300cm from the side of the door, the system will send text messages, photos, and videos via Telegram. That way, the user can determine the next steps related to the condition of the server room. However, if the RFID tag is recognized, the solenoid door lock, PIR, and ultrasonic will be deactivated. Other features, Users can ask the system to record a video of the room conditions and also messages related to room temperature through commands sent via Telegram messages. Testing is carried out using 3 scenarios: testing command, testing regarding valid access, and testing regarding invalid temperature and intruder detection. Overall test results show all these tests were successful 100% and followed the objectives and program scenarios. This tool has fulfilled the objective where this tool can monitor the condition and security of the server room by utilizing IoT technology.

Saat ini masyarakat diresahkan dengan maraknya kasus kecurangan saat pengisian BBM di SPBU. Kecurangan yang dimaksud adalah volume BBM yang dimasukkan pada tangki kendaraan bermotor tidak sesuai dengan takaran seharusnya pada pembelian. Penelitian ini dibuat untuk membantu tugas UPT Metrologi dan Disperindag dalam pengawasan kecurangan pada alat ukur SPBU. Alat ini dipasang di dekat tangki sepeda motor untuk memudahkan kontrol. Alat bekerja deprogram pada Arduino Uno R3 untuk menampilkan perubahan volume bahan bakar awal dan setelah pengisian dengan input harga BBM yang akan dibeli. Untuk menambah keandalan, alat dilengkapi SMS Gateway yang terkoneksi dengan ponsel pengguna. Terdapat tiga pengujian pada alat ini yaitu pengujian akurasi pengukuran volume, pengujian performa deteksi kecurangan, dan desain keamanan implementasi. Hasil pembacaan akurasi dibandingkan pada hitungan matematis didapatkan nilai rata-rata akurasi sebesar 99,85% dan rata-rata error 0,15% sehingga telah memenuhi standar pengukuran BBM karena nilai error yang diperbolehkan adalah 0,5%. Dalam pengujian performa dalam mendeteksi kecurangan, alat bekerja dengan baik diindikasikan melalui notifikasi buzzer dan bukti transaksi melalui SMS gateway. Demi keamanan pengguna, implementasi sensor ultrasonik diberi lapisan karet dengan pemasangan fleksibel. Dengan adanya penelitian ini diharapkan dapat meminimalisir kecurangan pengisian BBM di masyarakat sekaligus menjadi rujukan salah satu metode pengukuran volume BBM yang akurat.

“…For example, multiple ultrasonic sensors are required to identify the vehicles' size due to the very narrow beam of the ultrasonic sensors [86]. However, ultrasonic sensors had been effectively applied for some warning automotive systems such as auto parking and detect blind spot [87], [88], vehicle's nearby conditions identifying [89], [90] and vehicle's location sensing in relation to devices and pedestrians [91].…”

<span lang="EN-US">Observing the vehicles movement becomes an urgent necessity due to exponentially increasing numbers of vehicles in the world. However, to this regard, a good deal of research had been presented to estimate the exact physical position of the vehicle. The major challenges faced vehicle localization systems are large coverage areas required, positioning at diverse environments and positioning during a high-speed movement. However, in this paper, the challenges of employing the vehicle localization techniques, which rely on the propagation signal properties, are discussed. Moreover, a comparison between these techniques, in terms of accuracy, responsiveness, scalability, cost, and complexity, is conducted. The presented positioning technologies are classified into five categories: satellite based, radio frequency based, radio waves based, optical based, and sound based. The discussion shows that, both of satellite-based technology and cellular-based technology are emerge solutions to overcome the challenges of vehicle positioning. Satellite-based can provide a high accurate positioning in open outdoor environment, whereas the cellular-based can provide accurate and reliable vehicle localization in urban environment, it can support non-line of sight (NLOS) positioning and provide large coverage and high data transmission. The paper also shows that, the standalone localization technology still has limitations. Therefore, we discussed how the presented techniques are integrated to improve the positioning performance.</span>
