Abstract

Cisanggarung River, a river in West Java Province, often experiences flooding. This study aims to discuss the magnitude of annual flood discharge that may occur in the Cisanggarung watershed. Rain data at each station in the Cisanggarung watershed from 2005 to 2017 were analyzed using descriptive-quantitative methods. Return period flood discharge 2, 5, 10, 20, and 50 years were compared to 2-yearly and monthly flood discharge. The results showed that the data followed the Log-Pearson Type III distribution. The return period flood discharge is: Q2= 181.518 m3/s, Q5 = 242.498 m3/s, Q10 = 283.109 m3/s, Q20 = 316.534 m3/s, Q50 = 373.369 m3/s, Q100 = 412.425 m3/s, Q200 = 452.013 m3/s, dan Q1000 = 546.683 m3/s by using the Nakayasu method. Based on the 2 annual maximum daily rains, 2005, 2007, 2009-2010, 2015, 2009-2017 has the potential to flood Q2, 2012 has the potential to flood Q5, and 2017 has the potential to flood Q10. According to maximum 2-daily monthly rainfall, in 2005-2007, January-April and November have the potential to flood Q2. December has the potential to flood Q10. These results are useful for flood control in the region to be more effective and accurate.

Abstract

Concrete houses have a higher social and economic status. This study provides another consideration for the selection of building materials (Wonorahardjo, 2008). There are several ways that can be used to make concrete lighter, including using lightweight aggregates, substituting coarse aggregates with foam agents, adding coconut shells and additives where coconut shell waste has not been used optimally. In this research, a lightweight concrete mixture made from additives 5M additive, foam agent and coconut shell using 3 kg cement composition. While the 5M additives variation of 3%, 5%, 10%, 15% of cement, 15 milliliters of foam agent and coconut shell of 1%, with consideration of the specimens for 28 days not soaked non-curing. The test specimen is made with a size of 15x30 cm. This study is to determine the weight, compressive strength of the lightweight concrete produced. The results of research on the use of additional 5M additives, foam agents and coconut shells cause concrete to be lighter and compressive strength decreases. The weight of light concrete at 28 days not soaked is 775 kg / cm3, while the quality of concrete is 22 kg / cm2.

Abstract

Surabaya as one of the metropolitan cities in Indonesia, has a high level of project development and an attraction for the community. This is predicted to provide potential changes in environmental quality such as decreased road performance, wastewater and increased volume of waste generation, increased noise and the emergence of community perceptions and concerns about the planned activity. The construction of construction projects will always produce a considerable amount of waste, so that if management is not carried out, the construction waste can become a serious problem for the environment. The waste management model is basically carried out through the stages of avoid, reduce, recycle, and dispoal. This study aims to determine the material that has the greatest potential to produce construction waste. The method used in this study is first to use the Pareto method, the first step that must be done is to rank using Trading Consumable Materials (TCM) based on the total price so that a large price is obtained into the first order, then using the Pareto method to determine the material to be investigated in determining the most construction waste. Furthermore, the second one uses the waste level calculation to determine the waste volume from the results of the Pareto analysis that has been obtained. Furthermore, the third is the calculation of the waste index to determine the volume of residual construction waste in the project in m2 in each day, and the last is the calculation of waste cost to determine whether a large waste volume will produce a large waste as well.

Abstract

Cement as a binder used in the mixture of concrete is a costly product and it is also harmful to the environment due to the emission of huge amounts of CO2 and other gases. Like cement the fine aggregate is also the main constituent of the concrete used as inert filler in concrete is also expensive. The researchers are probing towards the new inexpensive and environment friendly materials for the concrete. They have agreed over the point that by utilizing the recycled waste materials could be helpful in achieving the sustainable construction. So in this case a lot of research has been carried out for the utilization of rice husk ash as cement substitution and recycled waste glass as alternative of concrete fine aggregate. The outcome of this research is that these both green materials have enormous potential to contribute in the long-lasting handling of ineffectual solid waste, reduction of landfill sites, preserving natural resources and protecting atmosphere from extremely hazardous gases. The purpose of this review work is to summarize the previous research findings on utilization of rice husk ash and recycled waste glass as a substitution to the cement and fine aggregate respectively. This review paper will come up with the remarkable idea and valuable information for the upcoming researchers working for the aim of utilization of renewable and futile materials in the field of concrete technology.

Abstract

Safety non-performance has not only contributed to higher levels of injuries but also decreased total productivity in the building sector. Through improving standards of safety practices, the condition can be changed. This paper provides a framework for recognizing the most neglected safety practices that must be improved. The research was performed using a questionnaire survey of 33 safety practices. Data obtained through 210 questionnaires from respondents who were working on building projects in the Sindh Province were analyzed using statistical package for the social sciences. All safety practices have been prioritized based on their mean safety performance values. Statistics have shown that the average safety performance of the building industry is 60.596 per cent. Construction safety practices that need special attention are listed as; (a) People should work safely even when they are not being supervised (b) Safety training provided to the employees of subcontractors (c) Investigations carried out to identify the causes of accidents (d) Accidents are reported/recorded (e) throwing or dropping of material/equipment carelessly. The findings also have shown that the factor 'Accident reporting and investigation mechanism', has the lowest level of safety performance, accompanied by 'Workers' involvement', 'Safety training', 'Safety practices', 'Safety meetings. The findings of this report will provide building stakeholders with valuable knowledge for safe work practices.

Abstract

In the world the most widely used material is concrete. It is the second most consumed substance after water in the world and plays a vital role in infrastructure and private buildings construction. Various waste materials like coconut shells, date seeds, rubber seed shell, palm kernel shells, etc. were studied by various researchers and replaced for coarse aggregate in concrete making. This study attempted to use Date Seeds as partial replacement with coarse aggregate in concrete. The mix design ratio 1:2:4 of cement, fine aggregate and coarse aggregate/date seeds was investigated in this study work only. Total 24 number of Cylinders of diameter and height of 4’×8’ were made. The 0%, 2%, 3% and 4% of Date Seed were replaced with Coarse aggregate. The physical properties of Date Seed, fine aggregate and coarse aggregate were determined. The specific gravity of DS was found to be 1.0 and water absorption was 24% for 48 hours. The bulk density value was 843 kg/m3 which was greater than the previous research works, the fineness modulus of DS, CA & FA were 1.7, 2.18 and 3.08, respectively. Other important thing which was observed during this work that the DS were expanding on absorption of water. The workability of concrete was decreasing as the total surface area of coarser particles was increased. The results of compressive strengths were quite satisfied at 2% & 3% replacement.
