Abstract

DC motor is an electrical motor widely used for industrial applications, mostly to support production processes. It is known for its flexibility and operational-friendly characteristics. However, the speed of the DC motor needs to be controlled to have desired speed performance or transient response, especially when it is loaded. This paper aims to design a DC motor model and its speed controller. First, the state space representation of a DC motor was modeled. Then, the controllability and observability were analyzed. The transfer function was made based on the model after the model was ensured to be fully controllable and observable. Therefore, a fuzzy logic controller is employed as its speed controller. Fuzzy logic controller provides the best system performance among other algorithms; the overshoot was successfully eliminated, rise time was improved, and the steady-state error was minimized. The proposed control algorithm showed that the speed controller of the DC motor, which was designed based on the fuzzy logic controller, could quickly control the speed of the DC motor. The detail of resulted system performance was 2.427 seconds of rising time, 11 seconds of settling time, and only required 12 seconds to reach the steady state. These results were proved faster and better than the system performance of PI and PID controllers.

Abstract

Protokol Secret Sharing adalah metode yang digunakan untuk membagi atau memecah sebuah pesan rahasia (secret) kepada 2 (dua) atau lebih penerima, sehingga hasil dari pecahan pesan (shares) tersebut tidak dapat diketahui oleh para penerima secret, kecuali setiap penerima melakukan pertukaran shares untuk merekonstruksi secret. Permasalahan yang terjadi adalah ketika proses pertukaran shares, ada pihak lain yang mengetahui shares dari para penerima, maka pihak tersebut juga dapat merekonstruksi secret. Untuk menyelesaikan permasalahan tersebut, diperlukan pendekatan keamanan tambahan, seperti melakukan enkripsi pesan. Untuk itu digunakan Protokol Three-Pass, protokol ini akan mengamankan proses pertukaran shares antar penerima. Protokol Three-Pass juga memberikan kemudahan pada penerima untuk mengamankan share tanpa harus melakukan distribusi kunci enkripsi, dan share tersandi tersebut tetap terjamin keamanannya. Penelitian ini menganalisa keamanan pada pengiriman secret dengan mengkombinasikan Protokol Secret Sharing dan Protokol Three-Pass. Hasil penelitian ini menyatakan Protokol Three-Pass dapat mengamankan pertukaran shares, walaupun pihak penyerang mendapatkan shares tersandi pada saat pertukaran share, pihak tersebut harus melakukan brute-force terhadap shares tersandi tersebut sebanyak pn bilangan acak  (dimana p adalah modulo pada secret sharing, dan n adalah panjang share), dimana hal ini akan mustahil bagi pihak penyerang untuk mengetahui share yang benar, walaupun dia memiliki sumber daya komputer yang memadai.

With the application of information technology, a decision support system can be used to provide an assessment. Currently, there are many methods that can be used to assess employee performance. One of them is the SMART (Simple Multi Attribute Rating Technique) method. This method was chosen because of its advantages that able to solve problems using multicriteria so it is suitable for determining the employee performance assessment of an institution. The criteria used in the assessment are also important in determining the performance assesment. There are many criteria that can be used in determining employee performance assessment. In this study used five criteria, namely Discipline, Work Motivation, Responsibility, Leadership and Honesty. The research method used consists of the needs identification stage, needs analysis, SMART method analysis, and implementation in the form of testing the results of manual calculations applied to a web-based system. The calculation uses data from seven employees using five criteria. From the results of the tests carried out, it is known that the results of manual calculations are the same as the web system.

Abstract

The attendance or attendance system is a recording or provision of information on a person's presence which indicates that the person has provided information about his presence and absence, then it is stated in the form of an attendance report. Along with the development of technology, an attendance recording has also developed, where we used to use paper attendance to fingerprint attendance. In educational institutions such as campuses, attendance has an important role in the process of developing a student. Until now, there are still many campuses that still use conventional attendance to record the presence of students in class, which allows for human error or fraud from both lecturers and students. Therefore, a solution is possible to suppress errors that may occur, namely by creating a website-based attendance or attendance system where the QR Code is used as an auxiliary medium in recording the presence or absence of a student at the STMIK AKBA Makassar Campus.

Abstract

KNN categorization is simple and successful in healthcare. In this research's example case study, the KNN algorithm classified the new record as "Abnormal." The classification method began with choosing K, then calculating the Euclidean distance between the new record and the training set, finding the K nearest neighbors, then classifying the new record based on those K neighbors. The findings show that the KNN algorithm is effective in healthcare and highlight several shortcomings that should be addressed in future study. Weighting variables, choosing the best K value, and handling non-uniform data are these restrictions. The findings show the KNN algorithm's medical potential.

Abstract

The decision-making process is a crucial part of any business or organization, and the Decision Support System (DSS) using the Simple Additive Weighting (SAW) method is a widely used tool for evaluating multiple options or alternatives. This study aimed to determine the best location for a new retail store using the DSS and SAW method. Four criteria were considered in the evaluation process: population density, proximity to competitors, average income, and rent cost. Data was collected and analyzed, and the weighted scores were calculated using the SAW method. The results of this study showed that Location A had the highest weighted score, and thus was determined to be the best option for the new retail store. This study provides a reliable method for evaluating multiple options and determining the best one. It also highlights the advantages of using the DSS and SAW method, such as the objective decision-making process based on data and criteria, and the high reliability of the results. Additionally, this study also points out the limitations of not using the DSS and SAW method, such as the subjective decision-making process based on personal bias and low reliability of the results. The DSS SAW method can be applied in various decision-making scenarios, and this study can serve as a guide for future research and decision-making processes.
