Abstract

If we look at the ability to carry out routine administrative work, we see that there are several factors that need to be improved, so that the performance of the teaching staff at SMA Mahapatih Mojopahit Tangerang can be improved for the better. As it is known that office administrative work to support the teaching and learning process is very important. Because the management of school student data and the administrative process will lead to the success of teaching and learning in schools. So our goal as partners feels the need to increase cooperation in the form of skills training in the use of software packages, especially software that is commonly used in schools to manage student data and other administrative data. We chose MS Excel as the main material in the training because this software package is easy and practical to use for training school staff. Starting with teaching how to operate the software properly and correctly, and followed by examples and applications in making tables and simple calculations. The result of this training is an increase in the skills of school administration and teaching staff, so that performance in the administrative field which is an important factor in the teaching and learning process can be achieved more effectively and efficiently.

Abstract

Currently, many automatic and practical tools have been created. Including in the world of health, for example baby incubators. Baby incubators are generally used for babies born prematurely. Baby incubators generally still use manual methods in controlling the temperature of the incubator room, for example the temperature in the incubator is above the ideal temperature, or even the temperature is below the required temperature. So the role of the operator, in this case the doctor or nurse, is still dominant. With this problem, we need a system that can control and monitor the baby incubator temperature based on web and SMS, making it easier for doctors and nurses to monitor the baby's condition. This tool will be developed to be web and SMS based. With the development of this tool, it is hoped that it can help doctors and nurses in monitoring the condition of babies in incubators.

Abstract

Charging controllers are utilized in various electronic systems to manage and safeguard the charging and discharging rates of batteries. For off-grid photovoltaic (PV) systems, two main technologies are employed: Pulse Width Modulation (PWM) and Maximum Power Point Tracking (MPPT). This study compares two charging controllers in PV systems with the same technical specifications to evaluate their performance under similar environmental conditions. Both controllers are built on original firmware and hardware designs, incorporating PWM and MPPT technologies. Each PV system includes a charging controller, a 30 W solar panel, and a 12V 18Ah battery. During experimental trials, voltage and current measurements were taken at both the panel and battery during charging and discharging. The findings reveal that the MPPT controller achieves a higher average efficiency than the PWM controller, indicating that the technology used in the charging controller significantly affects efficiency, even in less than ideal solar radiation and temperature conditions. While the PWM controller is a more budget-friendly option with satisfactory efficiency, the MPPT controller outperforms it in efficiency.

Abstract

The internet has now become part of human life both in villages and cities, as long as it is still accessible by cellular communication networks, the internet will be easily accessible, by anyone as long as they have a device, this internet will hereinafter be called the Internet of Things (IoT), this internet in addition to providing Various information can also be used for control systems or control systems. To utilize the Internet, you need a device that has access to the internet network, the ESP32 microcontroller is one of the microcontrollers that can be used to access the internet, with this microcontroller it can also be used as a controller which can receive data from the environment and then process the data according to the embedded program. . It is possible that the microcontroller can be applied in plantations, how to create a minimum system design based on an ESP32 microcontroller with communication capabilities via the internet to be applied in plantations. The method in this research is the design and minimum design of a microcontroller-based system and how to integrate between microcontroller-based IoT devices and how SCADA protocols and technology can be implemented as a reliable system.
