Abstract

HRD (Human Resources Departement) atau pimpinan sering merasa sulit dalam memilih sesuatu mulai dari memilih sesuatu yang ringan dan sederhana hingga sampai ke hal yang sangat berat dan rumit. Pihak puskesmas kesulitan dalam penilaian kinerja pegawai yang sering terjadi kekeliruan data dari bagian administrasi seperti penilaian kriteria dan nilai lainnya sering terlihat tidak singkron, jadi diharapkan dengan adanya aplikasi ini nanti nya bisa membantu pihak puskesmas dalam meng query data tersebut. Maka solusi dalam sistem pendukung keputusan penilaian kinerja pegawai tersebut diperlukanlah suatu sistem pendukung keputusan dan menerapkan Metode AHP (Analytic Hierarchy Process).Sehingga dalam penilaian kinerja pegawai dapat dapat lebih terarah dan terstruktur.Dalam hal ini penulis menggunakan metode AHP karena metode tersebut dapat memecahkan permasalahan yang kompleks melalui pendekatan sistem dan pengintegrasian secara deduktif. Beberapa metode yang penulis bandingkan seperti SAW (Simple Addictive Weighting) yang dapat digunakan pada elemen-elemen sistem yang saling bebas dan tidak memerlukan hubungan linier. Dengan menerapkan sistem pendukung keputusan penilaian kinerja pegawai Puskesmas Sapta Taruna Pekanbaru dapat membantu dan memudahkan user dalam penilaian kinerja pegawai dan dapat mempermudah pengolahan nilai masing-masing kriteria. Abstrak (Human Resources Department) or leaders often find it difficult to choose anything from choosing something that is light and simple to something that is very heavy and complicated. The health center has difficulty in evaluating employee performance, where data errors from the administrative section often occur, such as the assessment of criteria and other values ​​that often look out of sync, so it is hoped that this application will later be able to help the puskesmas in querying the data. So the solution in the employee performance appraisal decision support system requires a decision support system and applies the AHP (Analytic Hierarchy Process) method. So that employee performance appraisals can be more focused and structured. In this case the author uses the AHP method because this method can solve problems through a systems approach and deductive integration. Some of the methods that the authors compare, such as SAW (Simple Addictive Weighting), can be used on independent system elements and do not require a linear relationship. By implementing a decision support system for employee performance appraisal of the Sapta Taruna Public Health Center in Pekanbaru, it can be more helpful and easier for users to assess employee performance and can simplify the processing of the value of each criterion.

Abstract

This research aims to investigate methods for handling class imbalance in machine learning models, with a focus on the Support Vector Machine (SVM) algorithm. We apply oversampling (SMOTE) and undersampling techniques to a dataset with class imbalance and evaluate the performance of SVM using these methods. Experiments are conducted using data from Twitter social media regarding the 2024 general electionsThe findings indicate that incorporating SMOTE effectively enhances the performance of SVM models, particularly within the SVM Polynomial variant. However, the use of undersampling shows limited impact on improving SVM model performance. This study provides valuable insights for researchers and practitioners in choosing the appropriate strategy for handling class imbalance in machine learning models.

Abstract

Jobsheet is a set of documents that contain instructions or guidelines for carrying out a specific task or job, usually in the context of education or training. Therefore, this study explores the implementation of English for Engineering (EFE)-based Jobsheets in the Light Vehicle Engineering Expertise Program at SMK Muhammadiyah 1 Pekanbaru. Aditionally, using a descriptive qualitative approach, this study involved 38 students and several teachers who are directly involved with EFE Jobsheets. Data were collected through interviews, observations, and document analysis. At the same time, it was found that the EFE Jobsheets had a positive impact on students' understanding and application of technical English, improving their competencies in terms of both technical and language skills. However, challenges such as students' weak English foundation, inadequate teacher competence, and limited resources were identified. Solutions to these issues include continuous teacher training, development of interactive materials, and collaboration with industry to offer practical experience. In spite of the promising results of the EFE-based Jobsheet implementation, continuous improvements in developing multimedia-based interactive materials and industrial simulations are essential to optimize learning outcomes.
