“…So that the IoT system must be equipped with reliable security, it is necessary to develop Cyber-IoT technology [2,16]. Research on the theme of the IEEE 802.15.4 protocol was completed in research [1] and [18], [20] while using LoRa and LoRaWAN were analyzed in detail in research [19,21,22], [31].…”

Presence is one of the inherent aspects of the students. The presence system conducted in kindergarten Nurul Huda Kotapinang still uses a conventional system in the form of absent notes or books. This is considered less efficient because the data written by the teacher on the students still use the Presence book that is vulnerable to damage due to exposure to water and destructive things. Based on the background of the problems faced by teachers in kindergarten Nurul Huda Kotapinang, the authors designed the information system for students. This system is designed using Visual Basic .Net. In contrast, the programming language used is VBsrift and MySQL database. This system is designed and built to facilitate the delivery of information. The primary purpose of this system is to make it easier for teachers to attend to their students. It can be concluded Development Information System Presence can replace the confessional way previously used in kindergarten Nurul Huda Kotapinang into Student Presence Information Systems Based Visual Basic. As a development, this present system was modified in its programming language to produce a platform that is compatible with the Internet of Things Technology.

“…Currently, robot applications Iota 2021, ISSN 2774-4353, 02, 03 151/168 using Arduino are applied to various objects such as robot boats, arm robots, Cleaning Robots, and Car Robots, and several methods using Artificial intelligence (AI) [13], Deep Learning, and Data Mining [6] are applied in them [1,8,9,22,23,24,25,26,27,46,47]. Moreover, the prototype robot cannot be separated from the wireless devices inside, usually using Bluetooth HC-05, WiFi module ESP32, ESP8266, Node32, and LoRa or LoRaWAN [2,17,18,19,20,21,45]; some research uses propagation analysis [14]. This can not be separated from the Internet of Things (IoT) [3] technology, where these Wireless devices connect the prototype, end-node, sensors [4], and Tx or transmitter to the Application server programmed using Python, C++ on the Internet Gateway used, also known as Application.…”

This study aims to create a robot prototype for a garbage collection ship made using an Arduino nano microcontroller. The prototype of this garbage collection robot vessel is controlled by an Android smartphone application that is connected via Bluetooth. The prototype of the robot of the boat was made to deal with piles of garbage that can cause flooding. The method used in making the prototype ship robot along with the controller application begins with identifying the problem, namely the problem of piles of garbage, then needs analysis. Moreover, in this research, what will be developed is in terms of design, ship robot prototype, and ship robot controller design. Next is implementation and testing. The prototype of the garbage collection ship robot uses an Arduino nano microcontroller and in making a controller application using Android Basic 4. Then the trial stage was carried out on an Android smartphone. The results of this study are a prototype ship robot that can move according to commands through a controller application.

In this work, we present power and quality measurements of four transmissions using different emission technologies in an indoor environment, specifically a corridor, at the frequency of 868 MHz under two non-line-of-sight (NLOS) conditions. A narrowband (NB) continuous wave (CW) signal has been transmitted, and its received power has been measured with a spectrum analyzer, LoRa and Zigbee signals have also been transmitted, and their Received Signal Strength Indicator (RSSI) and bit error rate (BER) have been measured using the transceivers themselves; finally, a 20 MHz bandwidth 5G QPSK signal has also been transmitted and their quality parameters, such as SS-RSRP, SS-RSRQ and SS-RINR, have been measured using a SA. Thereafter, two fitting models, the Close-in (CI) model and the Floating-Intercept (FI) model, were used to analyze the path loss. The results show that slopes below 2 for the NLOS-1 zone and above 3 for the NLOS-2 zone have been found. Moreover, the CI and FI model behave very similarly in the NLOS-1 zone, while in the NLOS-2 zone, the CI model has poor accuracy in contrast to the FI model, which achieves the best accuracy in both NLOS situations. From these models, the power predicted with the FI model has been correlated with the measured BER value, and power margins have been established for which LoRa and Zigbee would each reach a BER greater than 5%; likewise, −18 dB has been established for the SS-RSRQ of 5G transmission.
