Abstract

Surabaya merupakan kawasan pesisir yang diproyeksikan sebagai kawasan strategis untuk perkembangan berkelanjutan wilayah pesisir sesuai rencana pembangunan jangka menengah daerah kota Surabaya 2016-2021. Kawasan strategis wilayah pesisir yang berfungsi sebagai pendukung pertumbuhan ekonomi, dan penyelamatan lingkungan hidup sebagai upaya optimalisasi pembangunan kawasan pesisir, sehingga diperlukan studi untuk mengetahui pengembangan wilayah tersebut. Studi ini dilakukan untuk mengetahui kekuatan, kelemahan, peluang dan ancaman pada wilayah pesisir Surabaya. Peneliti melakukan pendekatan kualitatif pada analisis dan bersifat study case yang diperlukan. Analisis pada kegiatan ini menggunakan metode SWOT. Hasil Analisis SWOT adalah hasil perbandingan faktor internal dan eksternal, analisis dilakukan dengan matriks IFAS (Internal Factor Analysis Summary) dan matriks EFAS (Eksternal Factor Analysis Summary). Berdasarkan analisa SWOT dapat ditunjukkan bahwa pengelolaan wilayah pesisir Kota Surabaya sesuai dengan rencana tata ruang yang sudah dibuat, namun dalam realisasi harus memperhatikan komunikasi dan sosialisasi kepada masyarakat yang dinilai belum optimal, serta penanggulangan dampak dan perawatan lingkungan secara berkala sehingga ancaman pesisir dapat diminimalkan..

Abstract

The oil and gas industry is an essential part of the global energy supply. Offshore exploration and production are important. In drilling, both onshore and offshore, the Bottom Hole Assembly (BHA) plays a crucial role. Logging While Drilling (LWD) tools depend on electronic boards that are very sensitive to downhole conditions like high pressure, vibration, and temperature changes. When these boards fail, it can disrupt operations, increase costs, and affect safety. Traditional maintenance methods struggle because they can't respond to changing risk conditions. This study creates a probabilistic framework using the Hidden Markov Model (HMM) to estimate the failure risk of LWD electronic boards. The research uses operational data, including temperature, pressure, vibration severity, usage, and fault records as observation sequences. The model is trained with the Baum-Welch algorithm, which helps identify hidden degradation states and generate time varying failure probabilities. Results are divided into four risk levels: low, moderate, high, and extreme. This classification provides a clear risk profile for proactive monitoring. The findings indicate that HMM effectively captures degradation transitions. It also offers early warnings and improves the reliability assessment of LWD tools, potentially benefiting offshore asset integrity management.
