This study evaluates the effectiveness of customer acquisition and activation strategies in retail securities services using a Value-Added Analysis (VA Analysis) approach. Adopting a qualitative case study methodology, the research focuses on PT X, a national securities firm in Indonesia, and investigates the efficiency of its onboarding process conducted through digital channels. Data were collected via semi-structured interviews with operational and marketing personnel, a netnographic review of customer feedback on social media, and internal document analysis. The onboarding activities were categorized into value-added, Business-value-added, and non-value-added activities to assess their contribution to customer activation. Findings indicate persistent inefficiencies, particularly in sales-driven product alignment and incentive distribution processes, which hinder conversion from account registration to initial transaction. The study suggests that improving key performance alignment, automating verification systems, and leveraging data analytics are crucial to transforming the onboarding process into a more value-generating system. This research contributes to the application of VA Analysis in evaluating service processes within digital financial ecosystems and offers practical insights for enhancing acquisition-to-activation effectiveness in competitive capital markets.

Penerapan Rekam Medis Elektronik (RME) di fasilitas kesehatan, termasuk RSUD Ir. Soekarno Kabupaten Sukoharjo, menjadi penting untuk memenuhi Peraturan Menteri Kesehatan Nomor 24 Tahun 2022 yang menekankan aspek keamanan data. Namun, Sistem Informasi Manajemen Rumah Sakit (SIMRS) masih menggunakan metode autentikasi konvensional berupa username dan password, yang rentan terhadap kelalaian logout dan penyalahgunaan akses. Penelitian ini bertujuan untuk menganalisis performa modul autentikasi wajah yang diintegrasikan ke dalam SIMRS dengan menggunakan model Tiny Face Detector dari Face-API.js, dengan fokus pada tingkat akurasi identifikasi dan kecepatan respon sistem Pengujian dilakukan pada dua skenario: pengguna tanpa masker dan pengguna yang mengenakan masker. Hasil menunjukkan bahwa sistem memiliki akurasi tinggi dan respon yang cepat saat mendeteksi wajah tanpa masker. Sebaliknya, sistem gagal mengenali wajah saat pengguna memakai masker. Temuan ini menunjukkan bahwa autentikasi wajah dengan model Tiny Face Detector dari Face-API.js layak diterapkan dalam SIMRS, tetapi efektivitasnya bergantung pada kondisi wajah yang tidak tertutup masker. Penelitian ini memberikan dasar teknis bagi pengembangan autentikasi biometrik di lingkungan rumah sakit dan mendorong evaluasi lanjutan terhadap model yang lebih adaptif terhadap penggunaan masker.

Development of a recommendation system to determine recipients of Direct Cash Assistance (BLT) using the C4.5 algorithm hybrid method and decision tree. In the current era of digitalization, the BLT program is a solution for the Indonesian government to help people affected by the COVID-19 pandemic. In this study, we propose a recommendation system that combines the C4.5 algorithm and a decision tree to increase accuracy and efficiency in determining BLT beneficiaries. Primary data was obtained through interviews and observations, while secondary data was obtained from the village administration, written reports, journals, theses and previous research. The results showed that the C4.5 algorithm and decision tree hybrid method gave good performance in determining BLT recipients. The C4.5 algorithm is used to calculate the accuracy of the training data and testing data with a ratio of 80% : 20%, while the decision tree is used to create a decision tree that classifies prospective BLT recipients. This research fills in the previous research gap regarding the recommendation system for determining BLT beneficiaries. The results of this study are expected to provide useful information for the government in making decisions regarding the BLT program, especially at the village or sub-district level. With an accurate and efficient recommendation system, financial assistance can be provided to those who really need it, helping to meet the basic daily needs of affected communities.

Stamp duty is the only type of tax that is managed by the Directorate General of Taxes (DJP) through the outsourcing mechanism. Under this mechanism, the management of stamp duty is predominantly carried out by third parties, while the DJP acts as the principal overseeing the process. As previously researched, despite its advantages, the outsourcing mechanism also comes with weaknesses and risks. Therefore, controls are needed to ensure they align with the DJP's intended objectives. This research aims to evaluate the effectiveness of the internal controls implemented by the DJP in the outsourcing activities related to stamp duty management. The study takes the case study form and adopts a qualitative approach, evaluating the components and principles of the 2013 COSO Internal Control Integrated Framework concerning outsourcing activities in stamp duty management. Data collection involves document analysis and interviews with individuals directly involved in stamp duty management. The data is analyzed using maturity levels to determine the effectiveness of each control component and principle. The research results reveal diverse levels of control effectiveness. Among the five control components, only two are at an optimum level, while the others exhibit lower levels of effectiveness in control principles. This study provides recommendations to the DJP for enhancing internal control effectiveness, particularly in the aspects of supervising the internal control system, comprehensively identifying risks, and considering the potential for fraud in risk assessments. This research is expected to contribute academically and serve as a reference for regulators in making decisions related to stamp duty management.

Selecting the right drug product is an important aspect in pharmaceutical services, especially for customers who do not yet have a deep understanding of the content and function of each drug. The limited number of pharmacists at Hero Farma Pharmacy often causes the service process to be inefficient, especially when still relying on manual recommendation methods that take a long time. This study aims to design a recommendation system that can assist in drug selection by implementing the content-based filtering method. This system is built by processing product attributes such as drug name, category, indication, dosage form, and price to form a profile of each product. The level of similarity between products is then calculated using the TF-IDF and Cosine Similarity methods. The data used in this study were obtained from Hero Farma Pharmacy located in Surakarta, with samples of 10 different types of drugs. The implementation results show that the system can produce recommendations with a good level of accuracy, where Promag drug obtained the highest Cosine Similarity value of 43.03% based on the query entered. This system successfully provides drug recommendations that have similar characteristics based on user needs and can help customers in making decisions correctly and improve the work efficiency of pharmacy staff.

Libraries play an important role in supporting the learning process at school. However, in its utilization, students often find it difficult to find books that suit their needs and interests due to the non-optimal management of the book collection. This problem also occurs at SMP Negeri 1 Kartasura, where there is no system that can generate book recommendations automatically and relevantly. The purpose of this research is to build a Content-Based Filtering-based book recommendation system with the Vector Space Model method which is further developed by combining TF-IDF weights and word vector representation from FastText, resulting in the TF-IDF Weighted with FastText technique. TF-IDF is used to determine the importance of a word in a book description, while FastText is used to capture the semantic meaning of the word in more depth. The system is implemented using book collection data in SMP Negeri 1 Kartasura Library, with input in the form of keywords from users. The document vector representation resulting from the combination of TF-IDF and FastText is then calculated using cosine similarity to determine the most relevant book. Evaluation was then conducted using the Precision@10 metric against ten different keywords, and the system produced an average Precision@10 of 0.93, indicating that 93% of the recommendations provided by this system are relevant to the user's keywords.

The advancement of information technology has led to an increasing demand for computing devices, particularly laptops. The wide variety of options based on specifications, brands, and prices often makes it difficult for consumers to choose the device that best suits their needs. Therefore, this study aims to design a laptop recommendation system using the Content-Based Filtering (CBF) approach to provide relevant suggestions based on user preferences. The developed system applies Term Frequency-Inverse Document Frequency (TF-IDF) and Cosine Similarity methods to measure the similarity between key laptop features such as processor type, RAM capacity, storage, and graphics card. Laptop data was obtained through a web scraping process from trusted e-commerce websites and integrated into a web-based platform. Testing results show that the system can automatically generate personalized and highly relevant recommendations. The main contribution of this study is the development of an efficient content-based laptop recommendation system utilizing a combination of TF-IDF and Cosine Similarity techniques. In addition to facilitating faster decision-making in selecting a laptop, the system also demonstrates the practical application of machine learning-based recommendation technologies in the e-commerce sector. This research further provides a foundation for developing similar recommendation systems in other contexts that require content-based personalization approaches.
