  Abstract: This study aimed to build a prototype development on a data transmission system using the LoRa communication protocol by applying a mesh topology in areas that difficult to reach by Wi-Fi or internet networks, the position of the first IoT devices has a role as a gateway between the IoT devices and a server. To connect the IoT devices with a server, the location of the IoT devices must be in a strategic location therefore it can connect to the internet network. Then the second IoT devices has a role as a gateway between the IoT devices. This study emphasizes the use of a WEB interface application on a computer or laptop used by the user to control and monitor the condition of an electronic device that has a considerable distance. This study used the NodeMCU ESP8266 microcontroller which is used on the first IoT devices, then this study also used the Arduino UNO microcontroller which is used on every IoT device which is intended to carry out the process of sending data between IoT devices. The used of the LoRa module in this study was used as a communication medium between IoT devices, and the use of the DS18B20 temperature sensor was used as a data transmission parameter. Based on the trials that have been carried out, the results of the prototype system work well according to the available features, but there is still one obstacle in this study where the IoT device in carrying out the data transmission process will be disrupted if there is another device that has a frequency that resembles the IoT device used. and there are obstacles in the form of buildings or dense trees, resulting in disturbances in sending data. This IoT device can still be used to send data even though there are obstacles as previously mentioned, provided that the distance does not exceed 500 meters.

  Abstract: The Smart Class Room concept requires modern technology to control and monitor Liquid Crystal Display Projector devices. This technology can be created by implementing the Internet of Things. The LCD Projector can be controlled remotely via an android-based mobile application. Research and Development is the right method to produce prototypes. The results of the implementation of the system show that remote control via the internet using a realtime firebase database can be achieved in 3 seconds. The distance between the LCD Projector and the embedded system device can communicate well up to 2 meters using the Infrared sensor. Changes in Temperature and Ambient Light intensity can be detected within 500mS measurement time. Current detection shows 4 LCD status modes: ON, OFF-Fan On, Stand by and Off.

  Abstract: The purpose of this study was to examine the effect of my Shopee Advertising Feature on Purchase Decisions and Brand Awareness. Testing the effect of Brand Awareness on Purchase Decisions and analyzing the role of Brand Awareness in mediating the effect of my Ads feature on Purchase Decisions. This research is motivated by the phenomenon of inequality that occurs in economic conditions that are weakening due to COVID-19 but the purchase of fashion products has actually increased. Data obtained from the distribution of questionnaires is as much as 350 data. SmartPLS is used to find the outer model and inner model. The results of the data are reprocessed to determine clusters and classification using K-Means, Naive Bayes and K-NN in the RapidMiner application. The results obtained from this research are that my Advertisement Shopee feature has a positive and significant effect on Purchase Decisions and Brand Awareness. Brand awareness has a positive and significant effect on Purchase Decisions and Brand Awareness also mediates positively and significantly the influence of the My Shopee Advertising feature on Purchase Decisions. The results obtained from data mining processing are that the Naive Bayes algorithm is more accurate than the K-NN algorithm method in classification using split data and also cross validation.

  Abstract: The Development of information technology make a huge impact in various aspects of life. One of the biggest influences given by information technology is in government. Indonesia as a country that consists of various provinces are in great need of advancement in information technology. Advances in technology provide convenience to government institutions to coordinate with each other to help Indonesia become more advanced. Sistem Pemerintahan Berbasis Elektronik or SPBE is one example of advances in information technology that has been used by the government to provide the best service to its users. Before the SPBE there was a different term, which was E-Government. E-Government is one of the information technologies used by the government to provide services and information to public, people in business, as well as other matters related to government affairs. This study aims to determine the development of the implementation of E-Government in Indonesia, the concept of E-Government in Indonesia and the comparison of Indonesian E-Government with other countries. Keywords: Information Technology, History, Sistem Pemerintahan Berbasis Elektronik, E-Government

  Abstract: The use of Enterprise Resource Planning system in manufacturing companies aims to increase the companies’ productivity. In this case, an integrated ERP system could maximize the companies’ production. Thus, the researcher conducted a study that discussed the application of ERP Odoo V12.0 system in a chicken company. This research focused on inventory sectors. There is no special system to manage the inventory section. The business process reengineering that has been done were the automatic purchase process, a special system or module to manage the inventory, the transfer of blast freezing process to manufacturing module, and the inventory reports. Based on the system testing by using User Acceptance Test that has been done, the researcher received quite good responses. In this case, the scores obtained for the Inventory 1215 from 1760 (positive result).

  Abstract: Electricity is a power source to run various electronic devices. Problem that often occurs is that users forget to turn off or turn on their electronic devices, then prepaid and postpaid electricity users cannot monitoring the electrical power usage of their electronic devices in realtime. The designed device to overcome these problems has a working principle like a switch, but there has relays and several sensors. Controlling electronic devices can be done by user using main switch in designed device, switch button and timer feature in Android application, then user can also monitoring the voltage, current and power in realtime on Android application. The results of several tests that have been done show that the designed device and Android applications that have been built can run well, but the current reading generated by the designed device are still not perfect, adjustments are needed so power calculation is better.
