The teacher is a professional educator with the task of educating, teaching, guiding, directing, training, assessing, and evaluating students in early and secondary education in certain formal institutions. One of the problems faced by Al-Hamidiyah Middle School teachers is the low competency of teachers, especially in the use of computer technology devices. This is unfortunate, even though the demands on teachers' assignments are in line with the enactment of the 2013 curriculum, where teachers are required to work using applications, learning media using information technology, application-based assessment systems, computer-based national exams, and others. This obstacle occurs because there is still a lack of teacher motivation to add competence outside the main task for a variety of reasons conveyed. The approach used in this dedication activity with a persuasive-educative approach, by providing knowledge, understanding, and skills in using Microsoft Office. The method used in the form of lectures, practice, and discussion. The results of this dedication the teacher understands and is able to practice directly.

One of the great disasters on earth is forest fires. Attempts to detect disaster events have been made with the help of monitoring technology. However, the problem is that the sensor is less responsive to detecting the presence of fire. Furthermore, sending information about fire incidents throughout the forest cannot use the existing communication platform. Therefore, we designed a forest fire monitoring system using LoRa. This technology is based on wireless which can transmit data across the forest. To detect the presence of fire, Arduino Uno is used as a microcontroller that regulates input from the AMG8833 sensor and GPS Ubox 6M. The experiment shows that the AMG8833 sensor is more sensitive in detecting the presence of fire as the catch range changes between 3 to 10 meters. In that distance range, hotspots were detected 19.25 oC to 122.5 oC when testing the sensor node is done. The monitoring system developed in this study demonstrated that sensor nodes and gateways could communicate up to 500 meters apart with a signal quality of -134 dBm. The best LoRa configuration mode for this communication capability is a Bandwidth of 250, a Code Rate of 4/5, and a Spread Factor of 10.One of the great disasters on earth is forest fires.

Shrimp is one of the prima donnas of Indonesia's mainstay exports from the fishery sector which needs to be improved both in terms of quality and quantity. The use of aerators as an effort to improve the quality and quantity of harvest used by pond farmers today generally still uses a manual system, where the operation of the aerator is still based on experience, not from the quality of dissolved oxygen in the pond needed by fish or shrimp in the pond. In this study, the application of an aerator to improve the quality of dissolved oxygen both in quality and quantity, is equipped with an IoT (Internet of things) method that can instruct the aerator to operate as desired using a smartphone. The components used in this tool consist of solar cell panels as renewable power plants, Aerator Pumps, and ESP8266 WiFi. In this data collection activity, in fluctuating weather conditions. Especially during rainy conditions, data retrieval is paused because test conditions do not allow it to produce a current data reading of 0 amperes. From the logger data recording, it can be seen that the highest current value that can be absorbed through solar panels is 2.40 Amperes obtained on day 3 of testing

The usefulness of monitoring systems in the electric power system supports the importance of people's work today. One of which is the monitoring system at the generator. The monitoring system for Wind Power Plant (WPP), Solar Power Plant (SPP), and electricity from State Electricity Company (PLN) use IoT (Internet of Things) in the form of Sonoff Pow R2. With the monitoring system on this tool, the parameter values for WPP, SPP, and PLN can be seen and monitored online via a smartphone. The purpose of this research is to design a monitoring system for WPP, SPP, and PLN based on the Internet of Things (IoT) to determine the value of the output power. In addition, this system can distinguish load parameter values when WPP, SPP, and PLN are supplied directly (real time) and monitored online using the Sonoff Pow R2 app and the Ewelink App. This study uses the methodology that started the process of designing and manufacturing systems and designing the wiring that has been formed from the process of making tools and testing results. The results obtained from the experiment show that the current values in WPP, SPP, and PLN that appear on the monitoring screen are stable. The stable condition values are measured and tested when power is used when loading through sonoff. For the power value, the power value in PLN is stable, whereas in WPP and SPP has increased. For the voltage, the voltage value from PLN does not reach 220 V, whereas the voltage value from WPP and SPP reaches a value of 220 V.
