Abstract

Concrete is a composite building material made from a combination of aggregate and cement. The limitation of concrete material, in this case, is a fine aggregate (river sand). The utilization of sea sand as an alternative to fine aggregate in the manufacture of concrete is     motivated by the availability of sea sand in nature in very large quantities. This study aims to determine the comparison and how much the compressive strength of concrete produced when using sea sand. The test was carried out when the specimens were 7, 14, and 28 days old with the specimens used in this study were concrete cylinders with a diameter of 15 cm and a height of 30 cm. The results showed that the use of sea sand as a substitute for fine aggregate showed an average compressive strength in 7 days of 18.86 MPa, an average compressive strength of 14 days of 25.52 MPa, an average compressive strength of 28 days of 29.00 MPa. Then for the average compressive strength value of the use of river sand in 7 days is 17.17 MPa, the average compressive strength of 14 days is 23.24 MPa, the average compressive strength of 28 days is 26.41 MPa.

Abstract

Safety and accidents at work are the most serious thing to note, on building projects stroke center at Haji Hospital of Surabaya is still a lot of workers are less aware and less understanding about the safety and accidents caused due to neglect of the problem of workplace accidents. It is necessary to analyze the implementation of safety management system construction as well as the influence of the cost of the implementation of the project. This research method uses quantitative description based on the analysis about the application of the safety management system of construction on building projects stroke center Haji Hospital Surabaya, data collection through questionnaires (primary) which is distributed to 30 respondents consisting of the executive team (contractor), supervisory (MK) project and also some of the foreman of the workers, and observation and also documentation, where data is the results of the questionnaire were analyzed using the software IBM SPSS version 25, looking for the results of the multiple linear regression, T-test, an F-test. The results of linear regression analysis, T-test and F test obtained the value of T count > T table where X1 = 3,071, X2 = 5,5658, X6 = 3,006 and X7 = 3,560 and F count= 54,308 > F table = 2,46, the meaning that the variable of X1, X2, X6 and X7 are significant to application of safety management of the construction with the cost of implementation of construction projects

Abstract

The development of increasing infrastructure development gave birth to the rapid development of service companies engaged in construction. Delay is one of the obstacles to development because the completion time does not match the one specified in the employment contract document. The delay in the construction project means the increase in the timing of the completion of the planned project and is contained in the contract documents agreed by both parties, namely the first and second parties. This study is to look for factors that affect the delays of construction projects, identify the role of legislation, and identify contracts. This research method is qualitative that is by observation and interview with resource person from Dinas Pekerjaan Umum Dan Tata Ruang that is PPK and staff. Also speakers from private contractors are supervisors, structural estimators, and some staff. On the scope of Government projects, the three dominant factors that affect the construction project's delays are weather, labor, and design. On the scope of Private projects, the three dominant factors that affect construction project delays are weather, material, and finance. The laws governing the delay are Law No.2 / 2017 article 54 paragraph (1) and (2), Perpres No.54 / 2010 Jo Perpres No.35 / 2011 Jo Perpres No.70 / 2012 and LKPP No.14 / 2012. The clause on the delay in the government work contract is in the SSUK, namely the critical contract, the term SSKK, and the bank's guarantee. Clauses on Private contracts namely the breach of wanprestasi and sanctions, and bank guarantees.
