Enhancing Email Security Against Phishing Attacks through User Behavior Analysis and Data Loss Prevention (DLP)
No full textThis study was conducted and aimed to improve email security against phishing attacks through user behavior analysis and data loss prevention (DLP). Phishing attacks pose a significant threat to the protection of user information and privacy, especially for individuals who are less aware of phishing emails. Their vulnerability to such attacks not only compromises their own security but also poses a great risk to the company. This can result in huge financial losses. Thus, there is an urgent need to improve security measures for users and systems. This study will use the NIST Cybersecurity Framework 2.0. This framework provides a structured approach to identifying and analyzing user behavior. Then an assessment of the phishing simulation is carried out to pay attention to users who are vulnerable to phishing attacks. After assessing the phishing email, the DLP configuration is determined for preventive measures. The following are the core functions of CSF as a framework that will be used: Based on the phishing simulation conducted, the pattern is almost the same, displaying the sender's email domain that is very similar to the original. Employees are usually easily trapped if they do not read the domain carefully and immediately follow the instructions in the email body. Phishing emails typically have a business context and are assumed to be sent by a trusted person, such as a supervisor, a colleague from the same department, or a different department. User behavior analysis is key to identifying vulnerabilities to phishing attacks. Understanding how users interact with emails can help develop effective mitigation strategies. Implementing DLP as a layer of defense can proactively detect and prevent phishing emails from reaching users’ inboxes. Proper DLP configuration is critical to a successful implementation. User education and training are critical components to raising awareness of phishing threats. Equipping users with the skills to recognize and avoid phishing attacks can significantly reduce an organization’s vulnerability.This research was conducted in order to improve email security against phishing attacks through user behavior analysis and data loss prevention (DLP).

Spatial Analysis of the Economic Valuation of Mangrove Carbon Stocks in Banda Aceh City
No full textClimate change or global warming is caused by an increase in Earth's surface temperature due to the greenhouse effect, with carbon dioxide (CO₂) as the primary contributor. Rising CO₂ levels trigger atmospheric warming, sea level rise, agricultural disruptions, and more intense storms. Carbon absorption from the atmosphere can be achieved through mangrove forests, which serve as natural carbon sinks. However, mangrove deforestation leads to carbon release. This study aims to measure carbon stock and the economic value of mangroves along the coast of Banda Aceh City using NDVI analysis. The results indicate that the lowest carbon value is 2.49505 × 10⁻⁶ tons per hectare, demonstrating very limited carbon storage capacity in certain areas. The total economic value of carbon stocks in four mangrove areas is Rp 2,400,026,446. This study is expected to provide insights into global warming, support the role of mangroves as carbon sinks, and serve as a foundation for further research on climate change

Karakteristik Atenuasi Seismik di Pulau Sumba Berdasarkan Analisis Gelombang Coda
No full textCoda wave data from four stations are to understand seismic attenuation on Sumba Island. Specifically, we estimate the quality factor at 1 Hz (Q₀) and its frequency dependence (η) across multiple window lengths (20–120 s) and frequency bands (1–7 Hz) using waveform data from 394 local earthquakes. The aim is to evaluate how these parameters reflect crustal heterogeneity and tectonic activity. Results show that Q₀ increases with window length, indicating that coda waves progressively sample deeper and more homogeneous layers, while high η values at shorter windows suggest significant near-surface heterogeneity. These findings highlight a depth-dependent variation in seismic attenuation and structural complexity. The study reveals spatial variability, with MELO station showing anomalously high Q₀ values, likely due to localized site conditions or deeper structural influences. Sumba’s location within the tectonically active Sunda-Banda arc transition zone further supports these observations. The combination of low Q₀ and high η values confirms high tectonic activity, and the use of coda wave attenuation analysis offers a reliable, parameter-based framework for assessing seismic hazard potential in regions with complex geodynamics. This work fills a research gap by providing empirical data and interpretation for a previously underexplored area in eastern Indonesia

Optimalisasi Kolaborasi Ketamin-Propofol untuk Mencegah Penurunan SpO₂ pada Pasien TIVA di RSU Emanuel Banjarnegara
No full textIntroduction: Total Intravenous Anesthesia (TIVA) is a widely used anesthetic technique that relies entirely on intravenous agents. However, one of its challenges is the potential reduction in oxygen saturation (SpO₂) during induction. Ketamine and propofol are commonly used anesthetic agents and their combination is hypothesized to optimize hemodynamic stability and prevent SpO₂ decline. Objectives: This study aims to evaluate the effectiveness of ketamine-propofol collaboration in maintaining oxygen saturation during TIVA induction at RSU Emanuel Banjarnegara. Methods: This study was a quasi-experimental study with 50 TIVA patients who met the inclusion criteria. Result: The study found that patients receiving the ketamine-propofol combination exhibited a more stable SpO₂ level compared to those receiving propofol alone. The mean decrease in SpO₂ was significantly lower in the combination group (p < 0.05), indicating the protective effect of ketamine in preventing hypoxia. The combo group also maintained hemodynamic indicators including blood pressure and heart rate better. Conclusion: The simultaneous injection of Ketamine and Propofol is beneficial in preventing a drop in SpO₂ 1 minute after induction of anesthesia compared to the combination of Propofol alone.Pengantar: Total Intravena Anestesi (TIVA) adalah teknik anestesi yang banyak digunakan yang sepenuhnya bergantung pada agen intravena. Namun, salah satu tantangannya adalah potensi penurunan saturasi oksigen (SpO₂) selama induksi. Ketamin dan propofol adalah agen anestesi yang umum digunakan dan kombinasinya dihipotesiskan untuk mengoptimalkan stabilitas hemodinamik dan mencegah penurunan SpO₂. Tujuan: Penelitian ini bertujuan untuk mengevaluasi efektivitas kolaborasi ketamin-propofol dalam mempertahankan saturasi oksigen selama induksi TIVA di RSU Emanuel Banjarnegara. Metode: Penelitian ini merupakan penelitian eksperimental semu dengan 50 pasien TIVA yang memenuhi kriteria inklusi. Hasil: Penelitian ini menemukan bahwa pasien yang menerima kombinasi ketamin-propofol menunjukkan tingkat SpO₂ yang lebih stabil dibandingkan dengan pasien yang menerima propofol saja. Penurunan rata-rata SpO₂ secara signifikan lebih rendah pada kelompok kombinasi (p <0,05), yang menunjukkan efek perlindungan ketamin dalam mencegah hipoksia. Kelompok kombinasi juga mempertahankan indikator hemodinamik termasuk tekanan darah dan denyut jantung dengan lebih baik. Kesimpulan: Injeksi simultan Ketamin dan Propofol bermanfaat dalam mencegah penurunan SpO₂ 1 menit setelah induksi anestesi dibandingkan dengan kombinasi Propofol saja
