Abstract

The Way Mincang River, which is located in Pardasuka District, Pringsewu Regency, Lampung Province, is a periodic river whose flow often overflows during rainy season. The overflow of the Way Mincang River inundated several Pekon in Pardasuka District including the Pekon Tanjung Rusia, Tanjung Rusia Timur, Sukanegeri, Pardasuka and Kedaung. The aim of research to determine the flood discharge with a return period of 10, 25 and 50 years in 2 dimensions with the HEC-RAS v6.2 software, so that the water level and the area of flood-prone distribution in Way Mincang River can be identified. The research location is in Way Mincang Watershed with the downstream of river at coordinates 104.92 BT and -5.50 LS while the upstream of river at coordinates 104.92 BT and -5.57 LS with a river length of 10.29 km, average river width of 15 m-20 m and the study area 2371.34 Ha. The results of analysis show that discharge at periods of 10 years, 25 years and 50 years is 50.29 m3/sec, 63.11 m3/sec and 72.61 m3/sec. The maximum flood water level is 1.88 m in Pekon Pardasuka Timur and the maximum flood area is 0.31 km2 in Pekon Kedaung. Along the Way Mincang watershed is a flood-prone area where the entire pekon (village) is flooded but the coverage area is relatively small, namely <1 km2. This is confirmed by the ratio of total flood inundation and total area of only 5.24%. It is hoped that results of research can be used as a reference for stakeholders in terms of planning and improving Way Mincang Watershed.

Abstract

In general, risks in construction projects can affect project objectives, namely affecting costs, quality and time. In a construction project, a risk factor is a possibility that causes a loss. This study was conducted to determine the dominant risk factors and risk mitigation that caused delays in the implementation of the basic infrastructure and tourism support public facilities project at Benoa Harbor. In this study, data was collected through a questionnaire which was then checked for validity, correlation and reliability using SPSS. Furthermore, to determine the dominant risk, the Severity Index method is used. Based on this research, there are 20 risk factors that cause project delays. The dominant risks based on the level of risk are unexpected events (natural disasters, fires) of 12%, changes in work that has been completed by 10%, environmental changes including changes in weather or climate. at project sites by 10%, repairs that are not in accordance with specifications by 8%, and limited authority of personnel/owners in making decisions by 8%. The dominant risks identified in the project really need to find solutions because they have a very significant impact on project performance.

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

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

Concrete is a material that is commonly used to build infrastructure in various environmental conditions, but concrete has a weakness in environments exposed to salt water. So, the engineer intends to research the impact of exposure to sea water on the compressive strength and split tensile strength of concrete, and use GGBFS as a substitute for cement to reduce the impact of exposure to sea water on concrete. In this study, researchers will conduct experiments by exposing concrete to artificial seawater with dry-wet cycles with immersion durations of 24 hours, 16 hours, and 8 hours, as an interpretation of the tide cycle. The test results obtained are by adding 20% of GGBFS to the concrete mixture, the concrete will experience an increase in performance from 29.06 MPa on compressive strenght and 2.34 MPa on tensile split strenght to be 32.17 MPa on compresive dan 2.64 on tensile split strenght compared to concrete without the addition of GGBFS, and by exposing it to seawater for 24 hours, concrete with 20% GGBFS mixture has compressive strength which is better than normal concrete without GGBFS mixture, but with 40% GGBFS content the concrete will decreases in performance to 26.98 MPa. Meanwhile, based on the immersion method using sea water that has been carried out, the decrease in concrete performance is most significant to 24.15 MPa in compressive streght when it experiences an 8-hour soaking cycle. This proves that concrete exposed to sea water will experience a decrease in strength, especially in extreme tidal conditions. Utilization of GGBFS as a concrete mix is an effort to utilize waste, but there are ideal proportions and mixing techniques that need to be considered, so that waste concrete does not experience a significant loss of performance.

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

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.
