Abstract

Attendance is essential for an institution or institution; it can assess employee salaries and performance. The company that will be audited is PT Anugerah Familindo Lestari, a company that distributes beauty and hair and body care products. This company's problem is that the fingerprint machine used has an error, which causes several employees who have been absent but are not recorded in the system. Therefore, to implement a sound fingerprint attendance system, it is necessary to carry out a checking activity known as an information system audit. In conducting data and observations, the study used questionnaires and interviews with related information and document confirmation. So far, the system has been implemented to support attendance procedures. In this study, the selected domains are Deliver Service and Support (DSS) domain and Monitor, Evaluate, and Assessment (MEA) domain with a focus on IT Process DSS01, DSS04, DSS05, and MEA02. Based on the research conducted, the writer found that the average level of the DSS01 domain was 1.6, the DSS04 domain was 1.7, the DSS05 domain was 1.7, and the MEA02 domain was 1.8. In all the domains studied, the level of capability of the domain is still below the expectation; the author concludes that from the results of this capability level, PT. Anugerah Familindo Lestari still has much to do with the management and maintenance of their attendance system to increase the current level of capability because it is still quite far from the level expected by this company.

Abstract

After the Covid-19 pandemic passed, digital transformation occurred, namely the use of technology in various activities of human life, including at work. Regardless of age, position, or educational background, we all have to learn so as not to be left behind. Cleaning service (CS) work has been seen as easy and does not require technology, except for WhatsApp Messenger or Group communication tools. The ship engine distributor company has office and warehouse areas that require CS services to maintain cleanliness. So far, coordination of work or the presence of CS personnel has been carried out through face-to-face briefings and WhatsApp. However, after restrictions on meeting (physical distancing), PSBB, etc., it seems that the use of WhatsApp is considered insufficient to accommodate work needs in the field for CS. This research aims to design a Cleaning service application to handle difficulties in the field for managing work and reports. The system development method used is the Waterfall Model method. The results of this research aim to provide convenience for CS coordinators and companies in managing CS performance, making reports, and improving the quality of cleaning services in the field.ABSTRAKSetelah masa pandemi Covid-19 berlalu, terjadi transformasi digital yaitu penggunaan teknologi pada berbagai aktivitas kehidupan manusia, termasuk dalam bekerja. Tidak memandang usia, jabatan, atau latar belakang pendidikan, kita semua harus belajar agar tidak tertinggal. Pekerjaan cleaning service (CS) selama ini dipandang mudah dan tidak memerlukan teknologi, kecuali alat komunikasi WhatsApp Messenger atau Group. Perusahaan distributor mesin kapal memiliki area kantor dan gudang yang memerlukan jasa CS untuk menjaga kebersihan. Selama ini koordinasi pekerjaan atau kehadiran personil CS dilakukan melalui briefing tatap muka dan WhatsApp. Namun setelah terjadi pembatasan untuk bertemu (physical distancing), PSBB, dll, tampaknya penggunaan WhatsApp dinilai kurang untuk mengakomodir kebutuhan pekerjaan di lapangan untuk CS. Penelitian ini bertujuan merancang aplikasi Cleaning service untuk menangani kesulitan di lapangan untuk pengaturan dan pelaporan pekerjaan. Metode pengembangan sistem yang digunakan adalah metode Model Waterfall. Hasil penelitian ini bertujuan memberikan kemudahan bagi koordinator CS dan perusahaan dalam mengatur kinerja CS, membuat pelaporan, dan meningkatkan kualitas pelayanan kebersihan di lapangan.

Abstract

The development of digital technology has changed people's habits, including in the use of online transportation. Innovation in online transportation services makes it easier for consumers and drivers to find each other's locations find out the driver's identity, vehicle type, and save time. However, competition between online transportation applications often makes consumers compare prices from one platform to another manually. This is time-consuming and makes consumers prefer applications that offer cheaper prices, even though it requires more effort. This study is a price comparison system based on Progressive Web Apps (PWA) that allows consumers to compare prices from several online transportation applications more efficiently. This PWA-based system can be accessed via desktop or mobile devices, providing greater ease of access. In developing this system, the Waterfall method is used, where users are involved from the early stages to provide feedback so that the system can be adjusted to their needs. Comparative analysis is carried out to find similarities and differences in prices between online transportation applications. This study focuses on two main problems: how to design a website that is connected to various online transportation applications, and how the price comparison system works efficiently. The purpose of this study is to provide a solution for consumers who often compare prices between platforms manually, as well as to form a PWA-based price comparison system that facilitates access via mobile devices. The benefits of this research include increasing efficiency for consumers in choosing online transportation services, as well as encouraging healthier competition between online transportation companies through more competitive price offers. The implementation of responsive PWA to compare prices in real-time, provides a better and more efficient user experience. ABSTRAKPerkembangan teknologi digital telah mengubah kebiasaan masyarakat, termasuk dalam penggunaan transportasi online. Inovasi dalam layanan transportasi online memudahkan konsumen dan pengemudi dalam saling menemukan lokasi, mengetahui identitas pengemudi, jenis kendaraan, serta menghemat waktu. Namun, persaingan antar aplikasi transportasi online sering kali membuat konsumen membandingkan harga dari satu platform ke platform lainnya secara manual. Hal ini memakan waktu dan membuat konsumen lebih memilih aplikasi yang menawarkan harga lebih murah, meskipun membutuhkan usaha lebih. Penelitian ini mengembangkan sebuah sistem komparasi harga berbasis Progressive Web Apps (PWA) yang memungkinkan konsumen untuk membandingkan harga dari beberapa aplikasi transportasi online dengan lebih efisien. Sistem berbasis PWA ini dapat diakses melalui desktop maupun perangkat mobile, memberikan kemudahan akses yang lebih luas. Dalam pengembangan sistem ini, digunakan metode Waterfall, di mana pengguna terlibat sejak tahap awal untuk memberikan umpan balik sehingga sistem dapat disesuaikan dengan kebutuhan mereka. Analisis komparatif dilakukan untuk menemukan persamaan dan perbedaan harga antar aplikasi transportasi online. Penelitian ini berfokus pada dua masalah utama: bagaimana merancang sebuah website yang terhubung dengan berbagai aplikasi transportasi online, dan bagaimana sistem komparasi harga bekerja secara efisien. Tujuan penelitian ini adalah memberikan solusi bagi konsumen yang kerap kali membandingkan harga antar platform secara manual, serta membentuk sistem komparasi harga berbasis PWA yang memudahkan akses melalui perangkat mobile. Manfaat dari penelitian ini meliputi peningkatan efisiensi bagi konsumen dalam memilih layanan transportasi online, serta mendorong persaingan yang lebih sehat antar perusahaan transportasi online melalui penawaran harga yang lebih kompetitif. Penerapan PWA yang responsif untuk membandingkan harga secara real-time, memberikan pengalaman pengguna yang lebih baik dan efisien.

Abstract

Polycystic Ovary Syndrome (PCOS) is one of the most common hormonal disorders experienced by women of reproductive age and can lead to various health problems, including menstrual irregularities, infertility, and an increased risk of metabolic diseases. Early detection of PCOS is essential to minimize long-term impacts and improve the quality of life for patients. This study aims to identify effective data preprocessing strategies to enhance the performance of classification models for PCOS detection. The dataset used is open source, consisting of 541 participants with 45 clinical and laboratory features. The main challenges encountered include the presence of many missing values, an imbalanced target class distribution, and a large number of independent features. To address these issues, a series of preprocessing steps were applied, including missing value imputation, data balancing using the Synthetic Minority Over-sampling Technique (SMOTE), and dimensionality reduction using Principal Component Analysis (PCA). A classification model was built using the Random Forest algorithm, and its performance was compared before and after applying PCA. The evaluation results show that before PCA, the model achieved an accuracy of 87.5%, precision of 86%, recall of 86%, and an F1-score of 86%. After applying PCA, performance improved to an accuracy of 90%, precision of 89%, recall of 89%, and an F1-score of 89%. These findings indicate that the right combination of preprocessing strategies, particularly SMOTE and PCA, can significantly improve the efficiency and effectiveness of models in detecting PCOS, thereby supporting the development of more reliable medical decision support systems.

Abstract

A network equipment company specializing in the provision of switches and servers still faces challenges in stock management because the recording of outgoing goods and inventory withdrawal transactions is still done manually using notebooks and Excel. This condition causes problems such as delays in data updates, difficulties in monitoring stock availability in real time, and the risk of discrepancies between data and conditions in the warehouse. The objective of this research is to design and implement a web-based inventory application using a pull inventory approach, where stock is recorded only upon actual demand from projects or customers. This strategy helps reduce the likelihood of overstocking or understocking. Based on testing results, the developed application can support the recording of outgoing goods, provide real-time availability information, and generate useful reports for management, thereby supporting the efficiency, accuracy, and integration of the company's business processes.
