Abstract

Penelitian ini dilakukan untuk mengetahui kelayakan finansial pada Sistem Penyediaan Air Minum (SPAM) Regional 1 Provinsi Lampung. Penelitian mengenai kelayakan finansial perlu dilakukan untuk mengetahui apakah SPAM Regional 1 Provinsi Lampung layak untuk dijalankan dan dikembangkan. Penelitian ini menggunakan metode analisis statistik deskriptif kuantitatif untuk menganalisis cashflow, kelayakan finansial dan sensitivitas dengan alat analisis NPV, IRR, B/C Ratio serta Payback Period. Hasil penelitian mengenai kelayakan finansial yang telah dilakukan terdiri dari NPV, IRR, Net B/C Ratio, dan Payback Period. Nilai NPV di semua ROT menunjukkan nilai positif dengan tingkat diskonto sebesar 6 persen; Nilai Rasio BCR di semua ROT diatas 1; Nilai Rasio IRR di semua ROT kurang dari rate of return, dimana nilai rate of return diasumsikan sebesar suku bunga deposito yaitu 4 persen; Payback Period (PP) di semua ROT bervariasi dan semuanya lebih kecil dari umur ekonomis bangunan yaitu 20 tahun. Dari hasil tersebut dapat disimpulkan bahwa penilaian kelayakan investasi dari segi finansial pada proyek SPAM Regional 1 Bandar Lampung layak untuk dilanjutkan.

Abstract

The availability of reliable road infrastructure is an important factor in supporting transportation and mobility activities in educational areas. Campus roads as supporting infrastructure for academic activities are required to be able to provide an optimal level of service along with the increasing volume and traffic load. The increase in traffic load on the campus roads of the Politeknik Negeri Lampung has not been balanced by adequate road infrastructure conditions. Therefore, this study aims to conduct a case study of flexible pavement thickness design planning to support the improvement of road service levels on the Politeknik Negeri Lampung. This study was conducted on the Main Road of the Lampung State Polytechnic with the survey being carried out from Monday to Thursday for 6 hours/day. The analysis results show that the recommended flexible pavement structure design based on the 2024 MDPJ for a design life of 20 years is a 60 mm thick AC-WC, a 200 mm thick Class A Aggregate Foundation Layer, and a 150 mm thick Class B Aggregate Foundation Layer, with a degree of saturation (DJ) value of 0.345 in the stable flow category, but vehicle speeds are starting to decrease.
