Abstract

The increasing intensity and frequency of natural disasters require disaster risk reduction systems that are not solely technology-driven but are also supported by adequate digital infrastructure readiness and governance. Early Warning Systems (EWS) are widely recognized as strategic instruments for reducing disaster impacts; however, their effectiveness remains inconsistent across regions. This study aims to analyze the role of Early Warning Systems in reducing disaster impacts by emphasizing digital infrastructure readiness as a key determinant of system effectiveness. The study employs a qualitative descriptive-analytical method with a policy and system analysis approach, using secondary data from reputable scientific literature, national and international policy documents, and disaster management reports. The findings indicate that EWS often function only as information delivery mechanisms due to limitations in digital infrastructure, fragmented governance, and low levels of community digital literacy. The readiness of communication networks, data system integration, energy reliability, and institutional coordination are identified as critical prerequisites for transforming EWS into effective collective mitigation mechanisms. This study concludes that strengthening EWS requires a systemic approach that integrates technology, digital infrastructure, and disaster governance to achieve meaningful disaster impact reduction.

Abstract

PT PQR is a company engaged in the application of shipping services. It is important for PT PQR to manage and utilize information technology well, but there has never been an assessment of the management system and its application. The author conducted research to assess the management of information technology using the COBIT 4.1 standard, which has 34 processes. This research was conducted through observations, interviews, and measurement of maturity levels, with the aim that PT PQR knows the information technology governance that is carried out, and knows the gaps that exist so that they can be resolved immediately to improve services and compete with other companies. The results showed that the current maturity level at PT PQR is close to level 3, with 14 Information Technology processes in two domains, namely Delivery Support and Monitoring Evaluate. PT PQR has clear and written standard procedures regarding the procedures and management of information technology, which are socialized among management and employees. Overall, the maturity level evaluation shows that PT PQR has fairly good IT governance, with an average achievement close to the expected target. The DS domain has an almost optimal performance with an achievement of 99%, while the ME domain requires more attention to increase the achievement from 90% to 100%. Improvement efforts can be focused on areas that require improvement based on the findings of this analysis.

Abstract

Audit keamanan pada log web server menjadi tantangan akibat volume data yang besar serta keterbatasan proses analisis manual. Penelitian ini mengusulkan pendekatan deteksi anomali berbasis perilaku untuk mengidentifikasi aktivitas mencurigakan pada log Nginx menggunakan metode unsupervised learning. Kontribusi utama penelitian ini terletak pada integrasi fitur perilaku berbasis agregasi waktu (time windowing), meliputi request count, burstiness, rasio kesalahan (4xx), dan jumlah URL unik, untuk merepresentasikan pola akses pengguna tanpa memerlukan data berlabel. Deteksi anomali dilakukan menggunakan Isolation Forest, Local Outlier Factor (LOF), dan One-Class SVM, dengan evaluasi berbasis weak labelyang dikombinasikan dengan analisis distribusi fitur dan validasi perilaku. Hasil eksperimen menunjukkan bahwa Isolation Forest memberikan performa terbaik dengan nilai F1-score sebesar 0.285, diikuti oleh One-Class SVM (0.191) dan LOF (0.057), yang menunjukkan keunggulan metode berbasis isolasi dalam menangkap pola anomali pada data agregasi waktu. Analisis lebih lanjut menunjukkan bahwa data yang terdeteksi sebagai anomali memiliki karakteristik yang konsisten dengan aktivitas mencurigakan seperti web scanning dan automated bot crawling. Hasil ini menunjukkan bahwa pendekatan berbasis fitur perilaku dapat menjadi solusi awal yang efektif dan scalable untuk deteksi anomali pada log web server dalam kondisi tanpa label.

Abstract

Penguasaan teknologi informasi merupakan kompetensi krusial bagi pegawai instansi pemerintah guna mendukung efisiensi pelayanan publik dan tertib administrasi. Kegiatan Pengabdian kepada Masyarakat (PKM) ini bertujuan untuk meningkatkan kapasitas SDM bagi Pegawai Pemerintah dengan Perjanjian Kerja (PPPK) di Loka Monitor Spektrum Frekuensi Radio Pangkalpinang melalui pelatihan optimalisasi aplikasi perkantoran, khususnya Microsoft Word dan Microsoft Excel. Metode pelaksanaan dilakukan selama tiga hari yang terdiri dari tahap pembekalan materi dasar, workshop teknis secara hands-on yang disertai sesi diskusi interaktif di Soll Marina Hotel & Conference, serta tahap evaluasi melalui penyelesaian studi kasus mandiri. Hasil evaluasi kegiatan menunjukkan adanya peningkatan pemahaman dan keterampilan praktis peserta secara signifikan. Peserta kini mampu menyusun laporan teknis yang terstandardisasi menggunakan fitur styles di MS Word serta mengolah data teknis spektrum frekuensi secara lebih cepat dan akurat menggunakan fungsi logika di MS Excel. Simpulan dari kegiatan ini adalah pelatihan intensif dengan metode pendampingan langsung dan diskusi dua arah sangat efektif dalam memperkuat keterampilan digital pegawai PPPK guna mendukung produktivitas dan kualitas layanan di lingkungan Loka Monitor Pangkalpinang. Kata kunci: Kapasitas SDM, PPPK, Microsoft Word, Microsoft Excel, Loka Monitor.
