Abstract

This research is a research and development research that aims to find out the results of the development of tower slope monitoring tools using the ESP32 Microcontroller-Based Sensor Gyroscope and find out the test results of the tool tower tilt monitoring using the ESP32 Microcontroller-Based Gyroscope Sensor. The development model used in this study is a prototyping model with stages of collecting needs, building prototypes, evaluating prototypes, coding s i stem, testing sistem, evaluation sistem, use s istem. The data used are interviews, questionnaires, observations and measurements. The data were analyzed using descriptive statistical analysis techniques. Based on the results of this study, a prototype of a tower slope monitoring tool was produced that was used to monitor the slope of the tower remotely through the telegram application. From the test results of the tower tilt monitoring tool using the MPU6050 gyroscope sensor based on the ESP32 microcontroller, it was found that the average time it takes to receive notifications if they occur the slope is 3.21 seconds. The results of the pecan test n there is a difference in the angle read at a height of 1 meter is 0.3 degrees, a height of 2 meters 0.2 degrees, a height of 3 meters 0.22 degrees, and a height of 4 meters 0.18 degrees. The results of the functional suitability test show that the tool functions as designed. The usability characteristic of the tower slope monitoring tool gets an average score of being included in the excellent category.

Abstract

This research is research and development (R&D) which aims to produce an official letter management information system, a supporting system for calculating remuneration performance point recapitulation at Makassar State University. Application testing uses ISO/IEC 25010. This study uses the Waterfall development model consisting of five work steps, namely analyzing needs, conducting design, coding, testing and maintenance. The developed system is validated by two system experts, and two content or material experts. The data were collected using questionnaires, interviews and documentation as supporting data for the development of information systems. Data processing uses qualitative and quantitative descriptive analysis techniques. The test results prove that the official letter management information system that has been built meets ISO/IEC 25010 testing standards with the results of testing the functionality suitability aspect in the very decent category. Aspects of performance efficiency with good criteria, aspects of usability with very good category, security aspects obtained level 1 security is at low level criteria with sufficient information. Achievements in the reliability aspect have met Telcordia's testing standards. The maintainability aspect has met three Land testing standards. The compatibility aspect is very feasible and the portability aspect is in the very good category.

Abstract

Fault studies are an important part of electrical power system analysis. The purpose of this study was to determine the amount of line current at the point of disturbance when a three-phase balanced fault occurs in the real Sulbagsel electrical system. In this paper, a new hybrid FFA-ABC (Fruit Fly Algorithm-Artificial Bee Colony) method is proposed, which is one of the new methods used to calculate balanced three-phase short circuit currents in electric power systems, especially in the real Sulbagsel electrical system of South Sulawesi, Indonesia. The real electricity system of Sulbagsel was chosen as the research object because this system consists of 15 generators, 44 buses, 52 transmission lines, and 29 load buses with system voltages varying from 30 kV, 70 kV, 150 kV, and 275 kV so that this system is included in the complex system category. To test the effectiveness of the proposed FFA-ABC method, it was implemented on a real electric power system, namely the Sulbagsel System.  In addition, it can also be applied to IEEE electrical systems or other real electric power systems. The results of the new hybrid FFA-ABC method of the balanced short circuit analysis of the Sulbagsel electrical system are then compared using the FFA method, the ABC method, and the deterministic method (in this case, the bus impedance matrix (BIM) method). The simulation results obtained show that the FFA-ABC hybrid method is able to solve the problem of balanced short circuit analysis in the Sulbagsel electrical system in South Sulawesi, Indonesia which the largest fault current occurs when the fault is close to the slack bus generator (bus 2=Sidrap) of 18.9697 p.u, and the smallest fault current occurs when the fault is farthest from the slack bus generator (bus 44=Poso) of  0.8457 p.u.
