Abstract

In an effort to improve people's welfare through trade and service-based development supported by superior industry, special attention is given to the seafood processing industry in Pangkalpinang City. One of the infrastructure support systems needed to support UMKM-based seafood trade activities is the provision of standardized production facilities that can be used jointly by UMKM players. This service program aims to support the industry through technical assistance in planning the construction of Production Houses with IKM Centers. This facility is designed to provide production facilities that meet UMKM standards in order to strengthen trade based on superior industries. Assistance includes field observations, structural and technical analysis, and cost calculations to ensure optimal building design that meets needs. The building design uses a concrete structure and steel roof, with local cultural elements in the form of a gable roof and carved wooden plank typical of Bangka Belitung. The estimated cost of building construction is IDR 4,572,000,000.00 (four billion five hundred and seventy-two million rupiah)

Abstract

Infrastructure development in Indonesia is currently in a fairly massive development phase. To support this, the government of the Republic of Indonesia improves the quality of national development by continuing to adapt to existing technological developments, one of which is Building Information Modeling (BIM). In this case, the use of BIM in planning and designing a construction object becomes easier because it can be done simultaneously. In addition, the design produced through the BIM method also contains data and information that can be used in other phases of construction. One of the data produced is the quantity of materials that can be used to estimate construction costs. In this study, the use of the BIM method is intended to determine the comparison of the costs generated to the cost of conventional methods of the project. The results of the cost calculation obtained by the BIM method are cumulatively -2,06% lower than the conventional method. There is a varying cost deviation for each work item, with the smallest cost deviation being +0,48% for beam structure work and the largest cost deviation being +126,26% for stair work.

Abstract

A jetty is an essential element of port infrastructure yet remains vulnerable to lateral forces generated by waves, currents, berthing impact, and earthquakes, all of which can trigger structural failure. This study analyzes jetty performance by comparing two design approaches, soil-structure interaction (SSI) modeled with non-linear springs, and the conventional fixity-point method. A reinforced-concrete deck on steel pipe piles was modeled in SAP2000, with pile diameters of 24, 32, and 40 inches embedded in medium sand. Serviceability and ultimate load combinations followed BS 6349 and ASCE 7-10 provisions. The SSI analysis showed larger structural responses than the fixity-point approach, with peak deflection, bending moment, axial force, and shear force increasing by approximately 35 %, 21 %, 12 %, and 18 %, respectively. These differences arise because the fixity-point method considers soil stiffness only to the calculated fixity depth, potentially underestimating overall lateral demand. Both approaches indicate that a 40-inch pile driven no deeper than 30 m satisfies deflection criteria while limiting drive length, offering a balanced solution between safety and economy. Verifying fixity-point designs with detailed SSI analysis is therefore recommended for robust jetty construction.
