These delays can be attributed to various risk factors that have the potential to disrupt project timelines. This study focuses on identifying the risk factors that contribute to delays in road and bridge construction projects in the Pemalang district. A comprehensive review of relevant literature was conducted to identify these risk factors, which were then incorporated into questionnaires distributed among contractors, owners, and consultants. The questionnaire data was analyzed using the mean score ranking method, along with validity and reliability tests, and descriptive statistical analysis facilitated by the SPSS program. The research findings unveiled a total of 54 risk factors categorized into 11 distinct categories. Among these, the top 10 causes of delays in road and bridge construction projects in the Pemalang district were identified based on mean values ranging from 4.18 to 4.57. These factors encompassed issues such as shortages of construction materials (4.57), delays in goods delivery (4.48), equipment delivery delays (4.40), difficulties in contractor funding (4.37), inadequate workforce or inability to meet project demands (4.37), rainfall intensity (4.35), poor material quality (4.30), ordering time inaccuracies (4.27), insufficient skilled labor (4.23), and equipment damage (4.18). Furthermore, interviews were conducted with experts to discuss the 10 risk factors with the highest impact. Strategies to mitigate these risks were derived from these discussions. The outcomes of this research are anticipated to provide valuable insights for stakeholders involved in the planning and execution of road and bridge construction projects. By understanding the underlying risk factors and implementing the recommended strategies, it is expected that project delays can be significantly reduced in future endeavors.","PeriodicalId":378971,"journal":{"name":"Applied Research on Civil Engineering and Environment (ARCEE)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128542241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ferronickel slag is utilized as a binding agent. Furthermore, large concentrations of alkaline solutions (potassium hydroxide and sodium hydroxide) are utilized as activators to activate kaolin and initiate the geopolymer production process. From the test results, it can be concluded that sodium hydroxide and potassium hydroxide solutions are effective to be applied as an alkaline solution. The maximum unconfined compressive strength of the sample is about 530 kPa with a concentration of 10% of ferronickel slag and 10M of alkaline activator. This value is twice larger than if we applied cement to the soil with the same amount of concentration. Hence, the effect of the admixture of ferronickel slag and alkaline activator is more dominant than the admixture of cement only. Furthermore, the Scanning Electron Microscope and X-Ray Fluorescence Spectrometer tests were also carried out to investigate the chemical bonds that occurred in the samples. It is revealed that the geopolymer matrix envelops soil particles resulting from the geopolymer reaction. The composition of SiO2 and Al2O3 in the treated Petobo silty sand decreased. It might be due to the geopolymer reaction that occurs in the sample so that the content of SiO2 and Al2O3 compounds is reduced. Because it uses an activator in the form of a KOH and NaOH solution, there is an increase in the levels of MgO compounds in the sample compared to untreated Petobo silty sand.","PeriodicalId":378971,"journal":{"name":"Applied Research on Civil Engineering and Environment (ARCEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131066086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While rice straw is a plant that forms after the rice is harvested. Rice straws will usually be burned by rice farmers to produce fertile soil; however, this will encourage open burning which can destroy the sustainability of the environment which needs to be avoided. However, there are also many types of metal decks, including metal decks with Polyurethane foam (PU Foam) which are considered good sound absorbers and contain a mixture of chemicals that may be harmful. The existence of Rice Straw Fluff is expected to help those who are less able to get metal decks that are as good as metal decks with Polyurethane foam (PU Foam). Several tests were conducted to detect whether the products produced exceed the effectiveness and can work well. The first test is the Impedance Tube Method which is a method to detect and evaluate the efficient sound frequency level. By using this method, Rice Straw Fluff is tested, and the results and data taken are good and effective if used by consumers. The next test is the Fourier Transform Infrared Spectroscopy Method (FTIR) which is a method to detect the chemicals contained in Rice Straw Fluff and existing products. The result of this finding clearly shows that rice straw mixed with silicone rubber is alkaline in nature which is influenced by silicone rubber. While Polyurethane foam (PU Foam) is acidic which is influenced by the chemicals mixed to produce foam. Finally, Rice Straw Fluff is an innovative product that can maintain the sustainability of the environment and can help low-income users to get a metal deck that has the same uses and benefits as existing products.","PeriodicalId":378971,"journal":{"name":"Applied Research on Civil Engineering and Environment (ARCEE)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125724949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, comprehensive knowledge is urgently needed particularly to be seen as a major variable in transportation planning that sided with underprivileged groups of transport poverty. The study focused on describing the correlation between income and commuting transportation expenses. The analysis was carried out using two methods. The first method is a descriptive analysis used to provide insight into the patterns and characteristics of the data obtained from interviews with 421 respondents. The second method is regression analysis (linear and nonlinear) to explain the relation pattern between the dependent (commuting transportation expenses) and independent (income) variables. The study's findings demonstrate that transportation expenses follow a negative polynomial regression pattern on income, further implying that the percentage of transportation expenses in low-income communities is significantly higher than those in high-income communities.","PeriodicalId":378971,"journal":{"name":"Applied Research on Civil Engineering and Environment (ARCEE)","volume":"368 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123130458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Weir is designed with many hydraulic factors, including the coefficient of discharge (Cd). Characteristics of the value of Cd show a decreasing trend on triangular and rectangular weirs. The value of Cd varies based on the flow's characteristics and the channel's geometry. Estimation of the best Cd value in flow discharge engineering and sediment deposition is necessary to know the accuracy of weir geometry. Some plans in water treatment and water resource building sometimes assume a Cd value based on literature. This study aims to estimate the value of Cd based on variations in flow rate and was conducted on a laboratory scale with weir shape limitations in the form of triangles and rectangles. The water sample was discharged by a water pump into an open channel. The angle of the weir opening was determined for the rectangular and triangular weir of 90°. Flow monitoring included flow discharge through the use of a current meter. Water was recycled in each measurement with a total of 60 cycles. The Cd values in a triangular weir were greater than in a rectangular weir. The Cd values for the rectangular weir ranged from 0.068 to 0.089, while the Cd values for the triangular weir ranged from 0.557 to 0.598. This value indicated that the greater the flow rate, the lower the Cd value. Therefore, weir configuration of water discharged using a triangular weir was better than a rectangular weir at low flow rates, less than 0.05 m3/s.","PeriodicalId":378971,"journal":{"name":"Applied Research on Civil Engineering and Environment (ARCEE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122750561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
