Utilization of HEC DSS and HEC SSP Software for Rainfall Frequency Analysis in Drainage System Design for City’s Industrial Area
Full text linkThe analysis of designed rainfall frequency is a key input in various designing in the field of hydraulic engineering, such as floodplain mitigation, water structure construction, and flood inundation mapping. The calculation of rainfall frequency analysis still largely uses Microsoft Excel-based statistics that are calculated manually. The purpose of writing this article is to utilize HEC DSS and HEC SSP software in analyzing rainfall frequency at the measurement location. Measured rainfall data collected from the BMKG Hang Nadim rain station over the past 12 years has been inventoried in the HEC DSS and descriptions have been inputted in sections A to F. Then the data that has been input into HEC DSS will be integrated with HEC SSP. By plotting rainfall data at HEC SSP and running an analysis of the rainfall data, the rainfall frequency analysis at the measurement location was obtained. From running the HEC SSP with Normal, Log-Normal, Gumbel, and Log-Pearson III rainfall distributions, the distribution fit tests using the Kolmogorov-Smirnov method yielded the smallest error value for Log-Pearson III at 0.149 and for the Anderson-Darling method at 0.176. Therefore, the rainfall frequency analysis used is based on the Log-Pearson III rainfall distribution. Where the rainfall design values for return periods of 2, 5, 10, 20, and 50 years are sequentially 118.434 mm/day, 172.94 mm/day, 217.94 mm/day, 268.73 mm/day, 355.81 mm/day, and 442.90 mm/day. The rainfall frequency analysis results are used as input data to compute the flood discharge recurrence interval with the Rational methode. Using a flood discharge with a 10-year return period (Q10) and a concrete channel, the proposed drainage channel dimensions of 0.80 m and 1.20 m were determined

Research Trends and Exploration of The Impact International Certification on Industry Performance: A Bibliometric Analysis
Full text linkBackground: The development of the industry, which is increasingly oriented towards increasing competitiveness and quality, is closely related to the ownership of international certification in global competition. Industries that have international certification have a good reputation for improving industrial performance from financial and operational aspects. Purpose: This study aims to analyze research trends, conceptual networks of international certification, and their impact on industrial performance. Design/Methodology/Approach : The approach used in this study is exploratory with the help of bibliometric analysis visualization using r-packages and VOSViewer software. By using various exclusion and inclusion criteria, it was found that there were 450 relevant articles from the Scopus database in the 2014-2024 range with scientific fields, namely management, economics, business, and finance. Findings/Results: The results of the analysis show that there are positive and negative relationships due to the application of international certification. In general, the application of international certification has a positive impact in increasing consumer confidence, increasing the efficiency of company operations, broader market access, improving the image and reputation of the company in the international market. On the other hand, international certification does not always have a positive impact. In some cases, certification has resulted in high costs such as audit costs, training costs, testing, and periodic maintenance costs. In addition, the negative impact of international certification will increase the company\u27s administrative burden, orient the consumer focus on price rather than quality, and not always provide added value. Conclusion: Hopefully, this research leads to the conclusion that international certification research has prospects in the preparation of future stakeholder policies.Originality/State of art: This study fills a gap in the literature by introducing a comprehensive analysis of the effect of international certification on industry performance using bibliometric analysis. A comprehensive bibliometric study of this research trend is under-researched. Different from previous studies that only focus on one industry or certification type, this research conducts analyses across sectors and regions, offering a more in-depth global perspective. Bibliometric techniques such as co-citation and temporal analysis are increasingly being used to understand research patterns in the international certification literature
