Abstract

Attendance systems play a crucial role in human resource management by serving as the foundation for accurate and efficient employee presence tracking. PT Urun Bangun Negeri previously used a manual attendance method that was prone to data errors, manipulation, and inefficiencies in reporting. This study aims to develop a digital attendance application based on Android that integrates with a web-based backoffice system. The software development method used is the Waterfall model, consisting of requirement analysis, system design, implementation, and testing phases. Kotlin was used to develop the mobile application, while Laravel was used for the web system. Key features include GPS-based location validation and selfie verification for attendance authenticity. System testing using Blackbox and User Acceptance Test (UAT) methods showed that the application performed well, with a success rate of more than 95% and a very high level of user satisfaction. These results demonstrate that the developed system effectively enhances efficiency, accuracy, and transparency in the company’s attendance process.

Abstract

The implementation of the zoning system in student admission (PPDB) often raises challenges in determining eligibility based on domicile, requiring a data-driven approach to support the selection process. This study aims to classify new students of SMPN 16 Bogor for the 2025 academic year using the K-Nearest Neighbors (KNN) algorithm. The dataset consists of 1,153 student records with attributes including longitude, latitude, distance from home to school, and zoning labels. Preprocessing involved data cleaning, label encoding, and feature standardization before splitting the data into 75% training and 25% testing sets. The optimal parameter was found at K=18 with a minimum error rate of 0.1591. Experimental results showed an accuracy of 97% for training data and 84% for testing data, indicating that the model performs reasonably well despite signs of overfitting. This research contributes by demonstrating that spatial attributes can be effectively integrated into zoning-based classification and provides a foundation for developing more objective and adaptive decision support systems in the context of student admissions.

Abstract

The rapid population growth and urbanization in Jakarta pose significant challenges to the provision of efficient public transportation, particularly for Transjakarta, which often experiences fluctuating passenger volumes that complicate capacity management and operational efficiency. This study aims to model and predict Transjakarta passenger volumes using regression methods within machine learning algorithms, by comparing three models: Linear Regression, Random Forest Regression, and Gradient Boosted Trees Regression. The dataset consists of historical passenger records from routes S21 (Ciputat–CSW/Tosari) and S22 (Ciputat–Kampung Rambutan) covering the period from January 2022 to March 2025. The data were processed through several stages, including preprocessing, categorical variable transformation, train-test splitting, and model evaluation using Mean Squared Error (MSE), Root Mean Squared Error (RMSE), and the coefficient of determination (R²). The results show that Gradient Boosted Trees Regression achieved the best predictive performance with an R² of 0.73 and an average error of approximately 22,000 passengers, outperforming Linear Regression (R² = 0.65) and Random Forest Regression (R² = 0.63). These findings highlight that ensemble boosting is more effective in capturing non-linear patterns in passenger data, making it the most suitable predictive model to support operational planning, fleet efficiency, and the development of adaptive and sustainable public transportation policies.

Abstract

Sistem Informasi Perpustakaan ini merupakan hasil perkembangan teknologi sebuah aplikasi komputer yang nantinya diharapkan dapat membantu dan memudahkan pekerjaan manusia. Diharapkan pula sistem ini dapat membantu dalam kegiatan sehari-hari agar dapat efektif dan efisien. Penelitian ini berfokus pada sistem perpustakaan. Perpustakaan SMP Negeri 1 Klari Karawang memiliki permasalahan dalam perpustakaan, adapun permasalahan yang dihadapi dalam perpustakaan SMP Negeri 1 Klari Karawang tersebut masih menggunakan cara manual dalam proses pelayanannya sehingga membutuhkan sekali adanya suatu inovasi serta perubahan sistem yang terintegrasi berupa sistem informasi yang menunjang dan memberikan pelayanan informasi perpustakaan kepada siswa sekolah, Dengan adanya sistem informasi perpustakaan berbasis web ini diharapkan dapat membantu siswa agar lebih mudah mendapatkan informasi dan melakukan peminjaman buku serta dari sisi petugas perpustakaan mendapatkan kemudahan dalam pengolahan data peminjaman buku dari siswa. Metode perancangan dalam pembuatan sistem informasi perpustakaan berbasis website ini, penulis menggunakan metode waterfall. Implementasi sistem informasi perpustakaan ini dimulai dari Analisa kebutuhan lunak proses ini mengutamakan mengenai proses peminjaman buku, dan ada tahapan desain dengan cara metode waterfall diantaranya dengan merancang desain antar muka, menyimpan basis data menggunakan Mysql lalu membuat desain basis data dengan menggunakan ERD (Entity Relationship Diagram) serta LRS(Logical Relational Structure) untuk membangun relasi basis data (Database).

Abstract

Customer satisfaction is an important benchmark for the company. PT. Asli Isoae Solusine wants to improve the quality of its website exists so that customers are increasingly satisfied, but the company has not carried out an assessmen on customer satisfaction on the company profile page. The purpose of This research is to measure the level of superior quality of the company's website PT Profile Original Isoae Solusine based on user perceptions of this research using the webqual 4.0 method which has 3 main variables Usability (X1), Information Quality (X2) and Service Interaction (X3) to determine the effect quality of use, influence of interaction quality, and influence of information quality on a website. Using questionnaires as a data collection technique, Questionnaires were distributed to PT employee staff. Asli Isoae Solusine via social media. The overall quality of the https://isoae.id website is based on the R² value contributed 58% to user satisfaction. Service interaction makes a significant contribution to user satisfaction of 0.112 based on the output regression coefficients table. Usability and quality information has an influence but is not significant on user satisfaction of 0.044 and 0.011 based on the output regression coefficients table. This is possible occurs when users believe that the usability of the site and the quality of the information are not significant or only occasionally used by visitors.
