Abstract

Internal audit plays a crucial role in ensuring the readiness and compliance of Certificate Authorities (CAs) with internationally recognized information security standards, particularly the WebTrust for Certification Authorities and Network Security. This topic has become increasingly relevant due to the growing demand for reliable and regulation compliant digital signature services. This study aims to examine the implementation of internal audit based on the WebTrust standard within a digital signature service provider in Indonesia. The research adopts a qualitative descriptive approach, utilizing document analysis and in-depth interviews with personnel performing trusted roles. The internal audit process consists of five main stages: defining the audit scope, mapping relevant controls to the standard, collecting evidence from operational processes and systems, evaluating the implementation’s conformity, and compiling the final report along with improvement recommendations. The audit findings reveal that most issues are concentrated in CA Environmental Controls, which includes asset management, physical security, and the documentation of policies and procedures. These findings indicate the need for strengthening controls in these areas to enhance the organization’s security posture. The internal audit has proven effective in identifying weaknesses early, providing relevant improvement recommendations, and serving as a strategic step in preparing for the external WebTrust audit. Thus, internal audit can be a critical instrument in improving system reliability, strengthening information security governance, and maintaining trust in digital signature services.

Abstract

Stunting is a serious health issue in Indonesia, including in East Nusa Tenggara Province (NTT), which requires an analysis of public perception to support data-driven policies. This study proposes sentiment analysis using deep learning and machine learning approaches to classify public opinions regarding stunting from social media/online platforms. It aims to evaluate the performance of the BERT (Bidirectional Encoder Representations from Transformers) and SVM (Support Vector Machine) models in identifying sentiment (positive, negative, neutral), compare the advantages of BERT (transformer-based) and SVM (traditional machine learning) for sentiment classification tasks, and analyze the linguistic and contextual factors influencing sentiment polarity through text feature extraction. The research methods include collecting text data from digital platforms, text preprocessing, and model training with BERT embeddings as input features for SVM. The results are compared with traditional baselines (TF-IDF and word2vec) to measure accuracy improvement. The evaluation results show that for Negative Sentiment (86 tweets) Precision: 58%, Recall: 58%, F1-Score: 58%, Accuracy: 100%. Neutral Sentiment (814 tweets) Precision: 30%, Recall: 20%, F1-Score: 25%, Accuracy: 100%. Positive Sentiment (100 tweets) Precision: 60%, Recall: 75%, F1-Score: 68%, Accuracy: 100%. Meanwhile, SVM with various kernel types showed performance differences in sentiment classification.

Abstract

Information Technology (IT) has become an essential element of human activity, including the implementation of Corporate Social Responsibility (CSR) programs aimed at community empowerment. One organization conducting such programs is Foundation XXX, a non-profit focused on education that routinely carries out CSR initiatives in partnership with various stakeholders. This study seeks to evaluate the effectiveness of IT-based partnerships within the foundation’s CSR program. A qualitative approach was employed through in-depth interviews with stakeholders, field observations, document analysis, and a literature review. Findings indicate that using online communication platformsm such as Zoom and Google Meet, and digital monitoring systems enhances inter-party coordination, transparency in resource allocation, and community participation. IT also facilitates real-time progress tracking, enabling faster, data-driven decision-making. Nonetheless, challenges such as digital-literacy gaps, infrastructure limitations, and incomplete system integration still hinder optimal benefits. The research underscores the need for a comprehensive IT strategy encompassing literacy training, platform standardization, and a sustainable integration plan to maximize CSR impact. These findings are expected to guide similar organizations in designing IT-based CSR initiatives that are sustainable and results-oriented. Practical implications include formulating supportive policies and fostering multi-party collaboration to bridge technological gaps and ensure equitable benefits for all stakeholders within the organization

Abstract

Ensuring occupational safety in port operations is critical due to the inherently high-risk nature of maritime activities. This study presents an integrated application of the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) methodology across eight operational zones within a major container terminal. Using structured field observations, qualitative risk matrices, and industry-aligned compliance standards, hazards were systematically identified and categorized into low (5%), medium (87%), and high (8%) risk priorities. Key findings indicate recurrent hazards such as electrical shocks, slips, and container-handling incidents, with control strategies emphasizing administrative protocols, engineering measures, and personal protective equipment (PPE). The findings reaffirm that durable HIRARC implementation necessitates both engineering solutions and the active involvement of personnel, alongside an ongoing reinforcement of the safety culture. In this regard, the present study expands the occupational safety and health (OSH) knowledge by articulating a governance model for risk that is simultaneously generalizable and directly applicable to maritime terminals and comparably dense operational settings, effectively narrowing the distance between normative theory and tangible safety measures.

Abstract

Penyusunan jadwal kuliah merupakan sebuah elemen dari banyaknya elemen pendukung lainnya dalam sebuah kegiatan perkuliahan yang sukses. Tidak sedikit institusi perguruan tinggi yang masih menggunakan spreadsheet manual dalam pembuatan jadwal kuliah, masalah yang dapat terjadi pada penyusunan jadwal adalah konflik waktu dari dosen, penggunaan ruangan yang bentrok dan duplikasi data. Universitas ABC, khususnya pada fakultas IT mengalami permasalahan yang serupa pada proses pembuatan jadwal kuliah sehingga menyebabkan kurang optimalnya penyusunan jadwal dan memakan waktu yang lebih dari seharusnya. Penelitian ini memiliki tujuan untuk melakukan analisis, merancang, dan membuat desain sistem informasi penjadwalan mata kuliah pada fakultas IT Universitas ABC. Metode yang akan digunakan adalah Rapid Application Development (RAD) dengan tahapan perencanaan kebutuhan melalui wawancara dengan staf akademik, perancangan perilaku user dan bagaimana data disimpan, serta desain sistem dengan menggunakan wireframe. Perancangan sistem menggunakan Unified Modeling Language (UML) dengan melibatkan Use Case Diagram untuk memodelkan perilaku user dan Entity Relationship Diagram sebagai bentuk visual tentang bagaimana data disimpan pada sistem. Perancangan sistem mencakup beberapa fitur seperti pengelolaan dosen, waktu dan ruangan, validasi konflik otomatis, pengaturan preferensi waktu dan ruangan bagi para dosen, serta fitur pengajuan untuk revisi jadwal yang telah ditentukan. Hasil rancangan menunjukkan potensi besar dalam peningkatan efisiensi proses pembuatan jadwal kuliah dengan user friendly interface dan proses yang terstruktur pada sistem informasi penyusunan jadwal mata kuliah.
