Abstract

Soil has different characteristics so that it becomes a lot of problems in Civil Engineering construction, especially in foundation planning, it must be done carefully and use several methods as a comparison. This research is to compare the three methods of calculating the bearing capacity of bored pile foundations: Van Der Ween, Phillipponnat, and Meyerhof. The selection of an apposite method in bearing capacity analysis is important to confirm the safety of the building structure. The Van Der Ween Method is a more modern and detailed approach compared to the Meyerhof Method, it takes into account the negative impact of the lateral deformation of the pile, which improves the accuracy of its calculation. The Philipponnat Method is a method that combines aspects of both the Meyerhof Method and the Van der Ween Method, it considers load characteristics and soil properties like Meyerhof, while also accounting for lateral deflection of the piles like Van der Ween. The results show that each method has advantages and disadvantages in determining the bearing capacity of bored pile foundations. Analysis revealed factors such as pile diameter, soil depth, and maximum applied load affect the accuracy of the three methods. This research provides important insights for construction planners in selecting a suitable method for bored pile foundation bearing capacity analysis. It is recommended that soil characteristics and pile geometry be considered before selecting the most appropriate calculation method. This research can be extended by considering other methods and conducting validation through experimental analysis.

Abstract

Limapuluh Kota Regency is one of the rice producing districts in West Sumatra Province, so an irrigation network is needed to meet water requirement for agricultural productivity. The problem that occurs in the Batang Sanipan 2 irrigation area is the inability of water to flow through the service area to the end point of the irrigation area. Based on observations from e-PAKSI data from the Limapuluh Kota Regency Public Works Office, water can only flow up to a distance of 3.175 km from the intake gate and experience water loss along 1.445 km to the end of the canal. Therefore, it is necessary to study the analysis of irrigation water requirement in the irrigation area of Batang Sanipan 2, Limapuluh Kota Regency. This type of research is descriptive with a quantitative approach. Research methods carried out directly in the field. Based on data analysis, the results obtained from the manual calculation of KP – 01 the maximum irrigation water requirement with a value of 0.139 m3/second which occurred in March, while in the Cropwat software the maximum irrigation water requirement with a value of 0.149 m3/second which occurred in July. The results of measuring the discharge at the intake of the Batang Sanipan 2 weir obtained a discharge of 0.378 m3/second. Based on this, water is sufficient to flow through the entire agricultural area of the Batang Sanipan 2 irrigation area, but the current conditions are that water is not able to flow through parts of the Batang Sanipan 2 irrigation service area.

Abstract

ABSTRACT Concrete is a complex-composite material. Semen Portland or other hydraulic types of cements, fine aggregates, coarse aggregates, and water, with or without additional substance, are the major materials in making concretes. In this time, the concrete cost more expensive, despite of many infrastructure development that caused higher concretes demand, the increased of concretes cost also caused by the cements high-price as a result of higher PPN value 11% for cement production cost. Cement is highly affected the concrete cost, it is because cement is the major material in forming the concrete that is more expensive than other types of materials. Therefore, it is important to reduce the cement content to press the cost of concrete. This study done by utilizing the variation of added admixture additon superfluid L to reduce the use of cement and water contents by using trial and test method, and slump that was planned 10±2 cm. The reduction of cement for about 5% and 10% from the total weight of cement also there are 4 added variation of content of admixture additon superfluid L, they are 0.5%, 1.0%, 1.5%, dan 2.0% from the cement weight with FAS still about 0,5. According to the test of concrete characteristics such as compressive strength testing, porocity testing, and elastic modulus testing, generally by having more PSA and admixture additon superfluid L, the quality of concrete getting lower from the view of compressive strenght, porocity,or even elastic modulus. There was concrete mixture configuration while it was 28 days, the most effective variation of reduction cement and water content, also the added admixture additon superfluid L 0,5% that possess compressive strenght value around 26,328 MPa ; porocity value around 11,11% ; elastic modulus value about 21950,49 MPa and poisson rasio value around 0,21179. Key Words: water content; cement content; admixture; concrete characteristics.

Abstract

A Variation Order is a modification of the contract content that has been agreed at the pre-implementation stage. Variation Order often occurs in a construction project and has the possibility to have a positive or negative impact on the project implementation time. In the implementation of the Antasari Place Jakarta apartment construction project, there are 22 site instructions as an order for Variation Order work. In identifying factors affecting the Variation Order in this study, a questionnaire that has been validated by experts was used. This study identified 21 factors from the aspects of construction, administration, parties involved, and others that affect the Variation Order on the Antasari Place Jakarta Apartment construction project, with the most dominant factor affecting the Variation Order is the addition of work scope. Ranking of the most dominant factors using the Relative Importance Index (RII) method and ranked three factors with the highest RII values, namely due to the addition of the scope of work with an RII score of 0.900, design changes from planning with an RII score of 0.680, and changes in the scope of work at the construction implementation stage with an RII score of 0.620. The Variation Order work in the Antasari Place Jakarta Apartment construction project has no impact on the final completion time of the project contract because the project implementation has not entered the critical trajectory of the implementation time and is carried out during slack time.
