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

Natural and artificial rivers contain bed-load sediment materials with varying shapes and grain sizes influencing flow resistance, velocity, and discharge. This resistance is expressed by the Manning roughness coefficient (n), whose accurate estimation is essential for hydraulic analysis. While n is commonly obtained from Manning’s table, alternative methods based on hydraulic parameters, channel geometry, and sediment characteristics, such as the Keulegan, Mayer-Peter-Muller, Lane and Carlson, Henderson, Raudkivi, Subramanya, and Wong and Parker methods, can be applied for more site-specific estimations. This study utilized primary field data and secondary data to estimate n values using various approaches. The n values ranged from 0.096–0.148 (hydraulic parameters), 0.069–0.136 (channel geometry), and 0.009–0.018 (sediment-based methods). Error analysis comparing calculated and observed discharges showed that the channel geometry method yielded the most accurate results with an average error of 15.59%. In contrast, other methods resulted in significantly higher errors. Thus, the channel geometry approach is recommended for estimating the Manning coefficient in the Way Tapus River.
