Abstract

Health is an inalienable area of human life. Therefore, developments need to be made so that in the field of health can support human life in this era. The DEVELOPMENT OF CONTROL SYSTEMS AND MONITORING PAT development could be the development of a medical aid tool that greatly supports the performance of the medical staff.To change the settings and modes of the patient monitor in the room of isolation, it would be quite risky for doctors and nurses if they had to enter the isolation compartment at all times if only to see the patient's condition in a patient monitor device.The author intends to design a tool to make it easier for the doctor and nurse in controlling the patient condition with ESP32 based CAM WIRELLES, in this discussion the author uses ARDUINO UNO, BLUETOOTH MODUL HC-05, and the application Monitoring Patient Monitor.After testing, this device displays images with 2 MEGAPIXEL quality and the range power of the BLUETOOTH HC-05 Module so that the device is usable and suitable for testing. And the range power (connection distance/application on the device) is 1 – 8meters.

Abstract

This research focuses on developing a DC-DC converter voltage regulation system using an Arduino microcontroller, addressing the instability inherent in renewable energy sources like solar panels and wind turbines. Utilizing Proteus and LabVIEW, the study employs a quantitative deductive approach to experimentally simulate and model the system over four months at the Control and Automation Laboratory of Politeknik ATI Makassar. Key challenges of conventional converters, including limited PWM flexibility, output stability, and ripple reduction, are addressed through a closed-loop control system with voltage feedback. The methodology involves extensive parameter calculations derived from literature review and expected testing scenarios to ensure precise component selection and system performance. Specific calculations guide the determination of minimum component values, facilitating the desired input and output voltage levels with minimal ripple. Simulation testing validates the system's effectiveness, demonstrating successful integration between LabVIEW and Proteus through additional library utilization. The resulting DC-DC converter voltage regulation system enables more robust control through Arduino microcontroller, enhancing stability and efficiency in renewable energy applications.

Abstract

This design is a system development carried out by swallow breeders in stabilizing the temperature and humidity of swallow houses. This design uses the principles of the Internet of Things (IoT), which will monitor temperature and humidity through internet media. This design aims to make a temperature and humidity control system in the swallow house automatically and find out the level of accuracy of temperature and humidity readings in the design made. This design uses a Wemos D1 Mini Board microcontroller that controls components such as DHT22 sensors, DS18B20 sensors and relays. The result of this design can control the condenser automatically, when the temperature and humidity are above the standard temperature, it will turn on the condenser automatically.

Abstract

The process of giving directional information to assist airplanes in making an accurate landing at the airport of destination is known as aviation navigation. The VHF Omnidirectional Range is a crucial navigation tool for guiding planes to the airport (VOR). Since it costs a lot of money to learn how to fly an airplane, a VOR simulator was developed that can mimic the movement of an aircraft passing through the VOR. The simulation that was produced is a prototype that sends and receives signals to the aircraft utilizing an antenna and microcontroller as supporting hardware. The VOR/DME flight navigation system is constructed in this study using mathematical modeling; a formulation representing the essential features of the system is expressed as a set of connected variables. The ESP32 module that powers the system serves as a DME by sending out Bluetooth radio signals. where one ESP32 module serves as a DME object (moving DME) and three ESP32 modules serve as DME stations (ground DME). Information on the distance between the DME station and the DME object will be communicated using the MQTT protocol, and this data will be processed using the trilateration method to predict the location and movement of the DME object. The measurement accuracy at DME station 1, DME station 2, and DME station 3 are 99.52%, 99.92%, and 99.98% respectively. The enhanced capabilities to estimate the position of objects observed from different directions or omni-directionally on a two-dimensional scale are made possible by the performance results of combining the performance of three ESP32 devices as Distance Measurement Equipment (DME).

Abstract

Drying food products using traditional methods relying on sunlight takes a relatively long time, especially with unpredictable weather conditions. Essentially, artificial drying using heat-based equipment provides several advantages, including: independence from weather conditions, adjustable drying capacity, controlled temperature, no need for extensive space, controlled drying conditions, and guaranteed and uniform drying quality. Therefore, this design aims to create a food drying apparatus with PLC control. PLC is used as the controller for this drying apparatus, allowing automatic drying of certain types of food. In this design, we connect a DC motor to rotate the drying cylinder with a PLC device by creating a ladder diagram and determining the inputs and outputs in the CX-Programmer application. The design utilizes three inputs and two outputs. It is important that the I/O is readable by the PLC so that the system operates according to the programmed instructions.

Abstract

The role of information technology is currently developed according to the current rapid development of the times. The most developed types of information technology are web-based and mobile devices. Web-based and mobile devices are used to facilitate daily activities along with technological advances. One of the important things for everyday life by utilizing technological advances is in the field of health services, especially services at health clinics. In this regard, a web-based and mobile information system was designed at the Pajjaiang Makassar clinic to facilitate service. Making this system uses the waterfall method which is often used in the development of information systems or software. This system consists of 4 actors, namely patients, admins, doctors, and pharmacists. Patients are connected to the mobile application, while admins, doctors, and pharmacists are connected on the web side. The patient registers for the examination, the admin manages the patient's data, the doctor conducts the examination, and the pharmacist manages the available drugs. Everything is interconnected using mysql database as the database and Application Programming Interface (API) to connect it. With this web-based and mobile information system is a form of digitalization process in the field of health services.

Abstract

Power transformers are essential components in electrical power systems as they transform electrical quantities. In practical terms, electrical power systems may experience disturbances such as short-circuit faults, either between phases or to ground. One type of relay used to accommodate these faults is the Over Current Relay (OCR) for phase-to-phase faults and the Ground Fault Relay (GFR) for ground faults. This research evaluates the coordination settings of transformer protection systems at PT PLN (Persero) ULTG Jeneponto by analyzing the characteristics plot of each transformer unit. The evaluation results reveal intersecting characteristics on the high voltage (HV) and medium voltage (MV) sides of Transformers #3 Tallasa and #3 Bulukumba. By implementing recommended settings for these two transformer units, anomalies can be addressed, and the protection system can coordinate effectively.

Abstract

This study seeks to put into action and assess the effectiveness of a Suricata based Intrusion Detection System (IDS), on a Linux Ubuntu 22 04 operating system setup. Suricata was selected as the IDS for its features and strong performance, in identifying types of cyber threats. The execution procedure involves setting up Suricata through installation configuring it and conducting tests in a controlled setting. The efficiency assessment entails studying the detection accuracy alarm rate and response time of Suricata when confronted with attack scenarios. The findings, from the research are anticipated to enhance the protection of information systems that operate using Linux as their base platform.
