Abstract

Vocational High School (SMK) is a formal educational institution that prepares its graduates for the world of work. However, SMK Iptek Tangsel faces challenges in optimizing student data and overcoming labor shortages in the field of education administration. To overcome this problem, this study applies a prediction system using a data mining technique with the decision tree method. Aims to improve the accuracy of student graduation predictions. The methodology of this study adopts a quantitative approach with structured steps, including observation, interviews, data collection, and documentation. The results showed that the accuracy of Rapid miners in motorcycle and multimedia business engineering reached 98.49%, while in hospitality and accounting accommodation reached 99.05%. This graduation prediction system helps schools identify students at risk of not graduating and who are at potential to graduate, optimize data management, and enable appropriate interventions. This research makes a significant contribution to improving the decision-making process in the field of education through the use of data mining technology. Thus, the graduation prediction system can be an effective tool in supporting data management and increasing student graduation in vocational schools.

Abstract

Employee performance is a key factor in the success of an organization, because high employee productivity can increase operational effectiveness and efficiency. Various elements, such as leadership style, motivation, and work discipline, affect this performance. An effective leadership style can create a conducive work environment, which in turn motivates employees to work optimally. In addition, high motivation drives employees to achieve organizational goals, while good work discipline ensures that each task is carried out efficiently and in accordance with applicable procedures. Therefore, a deep understanding of these factors is essential to designing policies that can improve employee performance and support the achievement of overall organizational goals. This study aims to examine the influence of these three factors on employee performance at PT. Usaha Sarana Medika, using multiple regression analysis and data collected from 60 employees through questionnaires.

Abstract

K-24 Merpati Clinic is one of the health service facilities that handles various patient needs, including recording and managing medical record data. However, the recording process that is still carried out manually causes various problems such as delays in searching for patient data, the risk of losing archives, and inefficiencies in the management of medical information. This problem has an impact on the quality of services and the speed of medical decision-making by health workers. As a solution, a website application was designed for a medical record information system that can be accessed in an integrated and real-time manner. This application aims to assist medical and administrative staff in managing patient data digitally, from registration, diagnosis, to medical history. The method used in the development of this system is the Waterfall model, which was chosen because it has a systematic workflow and is appropriate for projects with clearly defined needs from the outset. The result of this study is a website application that has been tested using the black box testing method and shows that all functions run well according to user needs. This system is able to improve work efficiency, speed up patient data search, and minimize the risk of information loss. With the implementation of this information system, K-24 Merpati Clinic can provide faster, more precise, and digitally organized health services.
