Abstract:
In every building, a foundation is needed as a strong and sturdy building foundation. The foundation aims to support the building and pass the load on the building above it to a layer of soil that is strong enough to have a bearing capacity. To calculate the carrying capacity of the soil, there are many formulas that can be used. The results of each of these formulas produce different carrying capacity values. The purpose of this study is to calculate and analyze the bearing capacity of shallow foundations from the results of hand boring with the Terzaghi and Meyerhof methods. The results showed that the carrying capacity of the shallow foundation soil in the Terzaghi method was smaller than that of the Meyerhof method. The value of the terzaghi method is 353,443 KN /m2, while the Meyerhof method has increased by 70,094%, with a value of 601,185 KN /m2.

Abstract:
Fosroc Conplast R and Fosroc SP 337 are additives for the concrete mixture which are used to delay the setting time of the concrete mixture, thus, it can extend the time for the concreting work. Previous studies have verified that the addition of Fosroc SP 337 and/or Fosroc Complast R additives increases the compressive strength of concrete, but no previous studies have investigated the effect of adding these additives on the compressive strength of concrete with variations in water-cement ratio. Therefore, this research is conducted to investigate the effect of adding Fosroc Conplast R and Fosroc SP 337 additives on the compressive strength of concrete with variations in water-cement ratio, by conducting the test on properties of the materials for designing the concrete mixture proportion, then the compressive strength test is conducted and the compressive strength of concrete is compared with the design compressive strength based on SNI 03-2834-2000. The compressive strength test was conducted at the concrete age of 7 and 28. Concrete with the addition of 1% Fosroc Conplast R and 1% Fosroc SP 337 additives, produces a higher compressive strength than the design strength of normal concrete without additives, thus, this additive is applicable to extend the time for the concreting work in the construction field

Abstract:
The construction of a new road that crosses the village of Jerukwudel-Baran-Duwet, is one of the development projects aimed at the development of road infrastructure in the South Coast region of Java. The construction of this road is in the area of Gunung Kidul Regency which is has a karst morphology, it causes the formation of sink holes that can trigger the occurrence of soil sinking (luweng) and endanger buildings / construction above or surrounding areas. The research method conducted by the author is the retrieval of field data supported by geoelectric data. From the field, obtained 26 sink holes that are divided into 2 types, collapse sink hole (18 locatiosn) is on the cliff and has an average diameter of 1.1 meters. Then the drop out sink hole (8 locations) is on the body of the road, and has an average diameter of 0.9 meters. The dominant lithology is carbonate rocks (packestone, wackestone and crystalline rock). There are two morphology forms in this area, doline and cone karst, both forms are associated with the type of sink hole formed. Where on the doline found dropout sink hole and in cone karst found collapse sink hole. From the interpretation of geoelectric data, it can also be determined the potential of subsurface cavities and soil sinks that have formed on the surface.

Abstract:
Red brick is one of the materials that is still quite widely used in construction practice, because it is quite easy to get and the price is relatively cheap. Red masonry wall is a pair consisting of a binder (mortar) and a filler (red brick) known as masonry. Masonry generally provides durable construction, where the constituent material, mortar quality, and workmanship greatly affect the durability of the overall wall construction. The installation of infill walls causes the structure to become more rigid, which can sometimes cause different failure behavior between structures without infill walls and structures with infill walls. This also affects the capacity and ductility of the overall structure. Several research results show that the interaction of the infill wall with the framework is very effective in increasing the strength, stiffness, and performance of the structure in resisting lateral loads due to earthquakes. This study takes the example of a 4 (four) floor building. The analysis is carried out by modeling the walls in the SAP2000 software application, where the structural models include: Model I fully uses frame elements, Model II is a structure modeled by including infill walls without plastering as a shell element, Model III is a structure modeled using infill walls with stucco reinforcement as the shell element, and Model IV is a structure modeled using infill walls with stucco reinforcement and counter wire as the shell element. The comparison parameters in this study are structural strength and deformation. Based on the results of the analysis, Model II, 90% stiffer than the open frame structure (open frame) Model I; while Model III is 92% stiffer than Model I; and Model IV, 97% stiffer than Model I which, when viewed from the X-direction earthquake load. When viewed from the Y-direction earthquake load, the infilled frame structure for Model II is 88% stiffer than the open frame structure (open frame) Model I; while Model III is 91% stiffer than Model I; and Model IV, 99 % stiffer than Model I. Moment and latitude values ​​of Model II, Model III, Model IV are smaller than Model I both in terms of the X-direction earthquake load and the Y-direction earthquake load. Infill walls of Model II are larger than those of Model IV and Model III when viewed from the X-direction earthquake load or due to the Y-direction earthquake load. and very qualified for use in areas with high earthquake risk

Abstract:
The intake building for Embung Sei Bubu had been designed to be an open channel with the flood gate. The flood gate had been designed from steel with a net width of 1.35 m and the height of the door opening is 0.0076 m. The corrosion is one of the hazardous threat to the strengthness and durability of the flood gate. This research numerically models flood gate that was attacked by pitting corrosion. The pitting corrosion had been modelled in several small holes randomly were distributed on the surface of the flood gate, precisely on the surface of the water. The numerical modeling had been performed in finite element method utilized computer programs such Abaqus. The results showed there was a reduction in the capacity of the steel flood gate due the hole increasing. The reduction in stress capacity had been indicated by the stress concentration that was occured around the pitting corrosion. The stress reduction occured with the change in the percentage of pitting corrosion distribution area of ​​10% (225 MPa), 20% (175 MPa) and 30% (120 MPa)
