Abstract

Bridges represent a vital component of strategic infrastructure, facilitating the movement of traffic and the distribution of logistics. Bridges facilitate connectivity between disparate geographical regions. It is of the utmost importance to prevent damage and failure of bridge structures. Bridge structure failure is the formation of local scour at the pillars and abutments of the bridge. The objective of this research is to assess the safety of the Way Sumanda-Sukamulya Bridge in regard to the potential for scour at the pillars and abutments. Topographic surveys, instantaneous discharge, and riverbed sediment gradation were conducted for the purpose of collecting data regarding the potential for scour. Ten years of rainfall data were obtained from the Mesuji-Sekampung BBWS, which served to corroborate the design flood discharge. An evaluation of scour was conducted using the HEC-RAS 1D.  The scour depth at the pillars ranged from 1.60 m to 1.89 m, while the scour depth at the abutments reached 2.28 m to 3.17 m. It was observed that the outer bend of the river presented a greater scour depth than the inner part. It is imperative that the Way Sumanda Bridge be periodically assessed to ensure that the risk of local scour is kept to an absolute minimum.

Optima Nusa Tujuh to enhance maritime distribution. This study aims to determine the most optimal investment scenario based on financial feasibility and its impact on distribution efficiency. A descriptive method is employed, incorporating both qualitative and quantitative approaches. Qualitative analysis explores non-financial factors influencing project viability, while quantitative analysis evaluates financial feasibility using NPV, IRR, PI, BCR, BEP, and PBP. Analysis of five investment scenarios reveals that all are financially feasible with positive NPV values; however, only moderate to optimistic scenarios fulfill all feasibility criteria. Scenario 5 (20% optimistic) emerges as the most optimal, yielding the highest NPV of IDR 65,396,124,689.67, IRR of 34,21%, and the shortest payback period of 3 years, 2 months, and 4 days. In conclusion, maritime distribution via dedicated terminal is feasible and financially advantageous, ensuring long-term gains and efficient logistics.   Keywords: feasibility study, dedicated terminal, basalt distribution, NPV, IRR

Abstract

The sustainability of dam operations needs to be reviewed in terms of water availability, in order to maintain the sustainability of water demand in all sectors in the coming years. This study aims to analyze of water availability of the Way Sekampung Dam reservoir according to its needs using one of the applications of the dynamic program, Vensim. The study used data-driven scenario simulations on the Vensim application, to analyze key factors including available inflows, required outflows, storage capacity of the dam and plans to supply raw water over a 25-year period. The results show that the dam can supply raw water for Bandar Lampung, Beranti, Pringsewu and Metro City with a total capacity of 2,737 liters per second and support water needs for potential irrigation of 76,006 hectares. Optimization of the dam's storage operation can be achieved, with a target reliability of 100% occurring in 2027, the year when the dam's storage condition reaches its optimal level at an elevation of +125.23 meters. To meet downstream water demand, the dam's storage capacity must be maintained at an elevation of +124.0 meters or higher, with a volume of 68,060,000 m³ and an inundation area of 5,020.8 km2. If the water storage falls below this elevation, it will be necessary to update the water allocation policy, adjust management regulations, appropriate management strategies, including periodic updating of the reservoir operation rules and implementation of a flexible water release schedule, to ensure continuous water availability at the Way Sekampung Dam reservoir.
