Abstract

Institute of Technology Sumatra (ITERA), as an educational institution located in the Lampung Province, continues to strive for the development of educational support facilities such as lecture halls and laboratories. The ITERA campus is in an area with potential natural disaster threats like earthquakes, due to the tectonic activity of the Great Sumatran Fault and the subduction of the Indo-Australian plate and the Eurasian plate. To mitigate the risk of disasters on the ITERA campus, infrastructure development planning requires a seismic microzonation study. This research was conducted to determine the dominant frequency (f0​), amplification factor (A0​), and seismic vulnerability index (Kg​) using the Horizontal to Vertical Spectral Ratio (HVSR) method. The results show that the dominant frequency (f0​) values range from 1 to 4 Hz, the amplification factor (A0) from 1.8 to 4, and the seismic vulnerability index (Kg​) from 2 to 15. The seismic microzonation map of the ITERA campus, the northern part of the area is categorized as having a medium to high seismic vulnerability index (Kg​), with a low dominant frequency (f0​) and a high amplification factor (A0​).

Abstract

Pemilihan vendor yang tepat sangat krusial dalam mendukung kelancaran proyek pembangunan. Penelitian ini bertujuan untuk menentukan vendor terbaik dari tiga kandidat dengan menggunakan metode Weighted Sum Model (WSM). Empat kriteria digunakan dalam penilaian yaitu biaya, kualitas, waktu penyelesaian, dan reputasi, masing-masing dengan bobot 0.4, 0.3, 0.2, dan 0.1. Hasil perhitungan menunjukkan bahwa Vendor C memperoleh skor tertinggi yaitu 7.7, sehingga dinyatakan sebagai vendor terbaik.
