Abstract

CV. Sumber Solusi Bersama, a software house company in Sukoharjo, faces challenges in the employee recruitment process that is still done manually. This research aims to develop a decision support system (SPK) for employee admission using the Simple Additive Weighting (SAW) algorithm. The SAW algorithm was chosen because of its ability to analyze and give weight to each criterion for the best decision-making. This research uses the waterfall system development method which is part of the System Development Life Cycle (SDLC). This system is expected to increase efficiency and accuracy in the employee selection process, as well as support fairer and more appropriate decision-making. Software feasibility testing conducted by CV. Implementation of SPK with SAW algorithm in CV. Sumber Solusi Bersama provides an alternative way to select employees that is more systematic and structured, so that it can help in achieving the company's strategic goals.

Abstract

Job search apps like KitaLulus are essential in helping graduates find jobs based on their skills and interests. Sentiment analysis is needed to understand user opinions about the KitaLulus application. The Naive Bayes method is used in this analysis because of its high efficiency and accuracy. This research used 597 data and achieved an accuracy rate of 91%. The eval_uation results show positive sentiment values for precision, recall, and f1-score of 0.99, 0.94, and 0.97 respectively. On the other hand, the model performance is low for negative and neutral sentiments. The aim of this research is to increase user understanding of the KitaLulus application and provide valuable assistance to developers in their efforts to improve the quality of the application.

Abstract

Camping is a favorite activity for various age groups carried out in the open air to enjoy the beauty of nature and get away from the noise of the city. The high cost of camping equipment encourages many people to prefer renting rather than buying, making Berkah Outdoor45 the main choice for nature lovers to rent camping equipment. This study aims to develop a recommendation system for selecting camping equipment using a content-based filtering mechanism with a TF-IDF approach to help users choose equipment that suits their needs. This study uses a waterfall system development model which includes the stages of analysis, design, implementation, and testing. Testing is carried out using the Blackbox method to evaluate the effectiveness of the system. The results showed that from 18 datasets, the system can provide four recommendations with the highest similarity values, namely D11 (0.377), D18 (0.354), D2 (0.320), D5 (0.311), and D1 (0.287) based on a predetermined formula. The recommendation system developed successfully provided accurate recommendations that were in accordance with user preferences, while reducing ordering errors and increasing efficiency in selecting camping equipment.

Abstract

Employee performance appraisal is a crucial aspect of human resource management, as it influences strategic decisions such as promotions, rotations, and incentives. However, manual evaluations are often prone to subjectivity and inefficiencies in terms of time and effort. This study aims to design and implement a decision support system (DSS) using the Simple Additive Weighting (SAW) method to determine the best employee objectively and measurably. The research adopts a software engineering approach with the waterfall model through stages of requirement analysis, system design, implementation, testing, and maintenance. The developed system is web-based and incorporates five key criteria: productivity, loyalty, work attitude, team contribution, and innovation. The testing results indicate that the system can process employee data, compute preference values, and display final rankings accurately and consistently with manual calculations. The system is also equipped with result export features and a user-friendly interface that facilitates the evaluation process. This study contributes a digital tool that reduces subjectivity in performance assessments and improves HR operational efficiency. In conclusion, the implementation of the SAW method in a web-based system is proven effective for supporting multi-criteria decision-making in selecting the best employee and is suitable for dynamic work environments.

Abstract

Di daerah-daerah yang masih menggunakan inspeksi manusia sebagai norma, kesehatan masyarakat sangat berisiko akibat air berkualitas rendah. Dengan latar belakang tersebut, tujuan penelitian ini adalah untuk mengembangkan dan meluncurkan sistem pemantauan kualitas air di Desa Wonosari yang memanfaatkan Internet of Things (IoT). Untuk lebih melindungi penduduk dari bahaya kesehatan, sistem ini dimaksudkan untuk memberikan data akurat secara real-time tentang suhu air, kekeruhan, total padatan terlarut (TDS), pH, dan karakteristik lainnya. Teknik penelitian meliputi pengumpulan persyaratan, konstruksi prototipe, evaluasi sistem, dan pengujian. Berdasarkan hasil, sensor pH, kekeruhan, suhu air, dan total padatan terlarut (TDS) masing-masing memiliki akurasi 99,22% dan 98,26%. Perangkat tersebut juga lulus uji ketahanan dengan tingkat keberhasilan 96,66% dan margin kesalahan 3,33%. Hasil ini menunjukkan bahwa metode yang diusulkan meningkatkan efektivitas pemantauan kualitas air dan dapat meningkatkan aksesibilitas air, yang pada gilirannya meningkatkan kesehatan masyarakat. Hasilnya, teknologi ini memberikan pendekatan baru terhadap pemantauan kualitas air masyarakat yang aman dan efisien.
