Abstract

The hydrological component is the main component in planning water infrastructure. The quality and quantity of rainfall data recorded at each rain post is the most crucial component in hydrological analysis, so it is necessary to analyze the rationalization of the rain station network to obtain an effective and efficient one. This research was conducted in the Tukad Mati Watershed, which has an area of 44,667 km2, with the length of the main river reaching 22,429 km, and there are six rain stations spread across the watershed. Rationalization analysis was carried out using two methods, namely the WMO (World Meteorological Organization) and Kagan-Rodda methods. The analysis using the WMO standard found that all rain stations were less than the minimum density. Meanwhile, from the results of the analysis using the Kagan-Rodda method with a smoothing error (Z1) of 9.069% and an interpolation error (Z3) of 7.989%, it is recommended that four selected rain stations out of six rain stations, namely Ngurah rain station, Sanglah rain station, Sading rain station, and Kapal rain station.

Abstract

Poor safety behaviour is the leading cause of workplace accidents. One form of dangerous worker behaviour often seen in construction projects is not using PPE and not working according to procedures which are the biggest causes of workplace accidents. Risky behaviour has an essential role in explaining the possibility of work accidents. Therefore, to suppress dangerous behaviour, it is necessary to provide a stimulus to reduce the accident rate. One form of stimulation is given to construction workers, namely reward and punishment. This study aims to analyze the effect of punishment and reward on safety behaviour in construction project work. The population in this study are workers in the Aston Mojokerto Hotel building construction project. While the respondents as a sample were carpenters and coolies, totalling 36 people. The sampling technique used was the purposive sampling method. The variable in this study is the variable of punishment, appreciation functions as the independent variable, while the dependent variable is work safety behaviour. Analysis using multiple linear regression. Retrieval of data using a questionnaire. The study results explain that the punishment and reward variables significantly relate to the work safety behaviour variable. Reward and punishment variables simultaneously positively affect work safety behaviour variables. In contrast, the partial influence of punishment variables does not significantly impact workplace safety behaviour. This research implies the need for management in the field to carry out rewards and punishments for workers to improve work safety behaviour.

Abstract

Climate change due to increasing temperatures causes changes in sea conditions. Rising sea levels and increasing the occurrence of high waves are the impacts of climate change. This condition threatens the existence of small islands, including Indonesia. One of the islands that is vulnerable to this condition is Sophialousia Island which is the southern border of Indonesia and Australia. The vulnerability of Sophialousia Island was analyzed using the Integrated Coastal Vulneron ability Index (ICVI) and adding sea level rise parameters. The number of parameters reviewed are 7 (seven) parameters, namely the type of coastal slope, beach conditions, the percentage of coastal protection, storm events, rob events, sea level rise (SLR), and land use. CMS-Wave modelling is used for strategy simulation handling to reduce the risk of island vulnerability. The results of the vulnerability assessment by ICVI showed that Sophialousia Island was classified as high vulnerability due to climate change. So the recommended handling strategy is to build a floating breakwater and make a revetment. The floating breakwater reduces storm surges, and the revetment increases the island's elevation so it is resistant to SLR.

Abstract

One of the common problems in urban regions is urbanization, urbanization, and industrialization trigger land use change, this land use change urges green land in urban areas to shrink, triggering building density which in the future will lead to new problems such as limited natural resources, congestion, and air pollution, Badung is a regency that is currently being attacked by massive land changes, therefore this research was conducted to compare the level of vegetation density and the area of vegetation density using the Normalized Difference Vegetation Index (NDVI) technique in 2015 and 2021 over Badung Regency. The supervised classification method was used to produce four classes consisting of water, soil, settlement, and vegetation. The results of this study exhibited the land cover decreased between 2015 and 2021 in the vegetation class around 57.26 km2. On the other hand, there is an increase in the land cover class for the settlement, land, and water body categories of 47.38 km2, 4.08 km2, and 5.80 km2, respectively. These results were obtained with an accuracy rate and kappa coefficient is 89.27% and 0.86, respectively. This indicate the classification recult in this study was feasible to use.

Abstract

Complete rainfall data for an extended period is needed to facilitate hydrological analysis. However, there are many obstacles to obtaining the measurement rainfall data as a limitation of rain gauges, especially in remote areas. This study aims to determine the accuracy of rainfall data estimated by the IMERG (Integrated Multi-satellitE Retrievals for GPM) satellite and obtain a correction factor to improve its compatibility with measured rainfall data. The IMERG satellite rain data was corrected using the regression method and the average ratio. The accuracy of the IMERG satellite rain data against the measured rain data is measured from the NSE, R, RMSE, and RB values. The analysis results show that the accuracy of the GPM satellite daily rain data is very low but improving for the ten-daily and monthly periods. Generally, the best correction factors for daily, ten-daily, and monthly periods are obtained using simple linear regression methods and 2nd-order polynomials. The corrected IMERG satellite rain data increase in accuracy, where the monthly rainfall data performs well, the ten-daily data generally complies, and the daily data has not shown good performance. The average values of NSE, R, RMSE, and RB for daily data are 0.14 (poor), 0.37 (weak), 9.18 mm, and -0.12%, respectively; for ten-daily data respectively, 0.40 (fair), 0.63 (strong), 39.42 mm, and 1.47%; and for monthly data are 0.55 (fair), 0.74 (strong), 80.19 mm, and -0.07%. The ten-daily and monthly rainfall data from the IMERG satellite can be used as a rain source data alternative in the Bima and Dompu areas by applying a correction factor.

Abstract

Beton merupakan material yang umum digunakan untuk membangun infrastruktur pada berbagai kondisi lingkungan, namun beton memiliki kelemahan pada lingkungan yang terpapar air garam. Sehingga penulis bermaksud meneliti mengenai dampak paparan air laut terhadap kuat tekan dan kuat tarik belah beton, serta menggunakan Ground Granulated Blast Furnace Slag (GGBFS) sebagai pengganti semen untuk mengurang dampak paparan air laut terhadap beton. Pada penelitian ini, peneliti akan melakukan percobaan dengan memaparkan beton dengan air laut buatan dengan siklus kering basah dengan durasi perendaman 24 jam, 16 jam, dan 8 jam, sebagai intepretasi dari siklus pasang surut air laut. Hasil pengujian yang didapat adalah dengan menambahkan GGBFS dalam campuran beton sebanyak 20%, beton akan mengalami peningkatan performa dari 29.06 MPa pada kuat tekan dan 2.34 MPa pada tarik belah menjadi 32.17 MPa pada kuat tekan dan 3.64 pada kuat tarik belah, jika dibandingkan dengan beton tanpa tambahan GGBFS, dan dengan memaparkannya dengan air laut selama 24 jam, beton dengan campuran GGBFS 20% memiliki kuat tekan yang lebih baik dari beton normal tanpa campuran GGBFS, namun dengan kadar GGBFS 40% beton akan mengalami penurunan performa menjadi 26.98 MPa. Sedangkan berdasarkan metode perendaman menggunakan air laut yang telah dilakukan, penurunan performa menjadi 24.15 MPa ketika mengalami siklus perendaman 8 jam, dan pengeringan selama 16 jam Hal ini membuktikan bahwa beton yang terpapar air laut akan mengalami penurunan kekuatan terlebih pada kondisi pasang-surut yang ekstrim. Pemanfaatan GGBFS sebagai bahan campuran beton merupakan salah satu upaya pemanfaatan limbah, namun terdapat proporsi ideal dan teknik pencampuran yang perlu diperhatikan, sehingga beton limbah tidak mengalami kehilangan performa yang signifikan.

Abstract

The variable or construct of sharing knowledge is a multidimensional construct. The aim of this research is to test the validity and reliability of the indicators forming the knowledge sharing construct by conducting confirmatory factor analysis (CFA). The knowledge sharing construct is measured using 2 (two) dimensions, namely the tacit knowledge sharing dimension and the explicit knowledge sharing dimension, with 14 (fourteen) indicators that are in accordance with theoretical studies. Factors that influence tacit knowledge sharing and explicit knowledge sharing are analyzed based on field data collected from distributing 120 questionnaires to 40 DB projects in several cities in Indonesia. From the outer loading results, it can be seen that all construct indicators are valid where the resulting t-statistics value is > 1.96. Then from the results of the path coefficients, all first order constructs have a significant effect on the second order construct of knowledge sharing where the resulting t-statistics value for all first order constructs is > 1.96. This means that the knowledge sharing instrument developed has good construct validity and has a high internal consistency reliability coefficient.

Abstract

Airports serve as transportation facilities that can assist in mobilization and provide access to and from a region. In the context of the development of Rendani Airport in Manokwari, West Papua, an extension of the runway is being carried out. The use of a box culvert as a river channel and foundation for the runway must have sufficient capacity, as it is directly related to the safety of activities at the airport. Therefore, this study aims to calculate the planned flood discharge of the channel to determine the capacity of the installed box culvert. Furthermore, it aims to determine the minimum safe dimensions for the box culvert and assess the safety of the installed dimensions. The analysis used to solve this problem includes frequency distribution analysis, rainfall intensity analysis, the analysis of the runoff coefficient of the catchment area, calculation of the planned flood discharge, and an evaluation of the dimensions of the box culvert. The results of the calculation show that the capacity of the installed box culvert dimensions is 438.4 m³/s, and the planned flood discharge capacity for a 100-year return period is 215.26 m³/s. It can be concluded that the capacity of the installed dimensions is sufficient to meet the planned discharge. Therefore, the minimum existing box size that can be used is 3.1 m x 7 m.
