Abstract

Contruction expanded rapidly and spread in Lamongan, from fairly simple residential contractor to large developer continuing to explore in building construction. This research aims to know the comparative costs of wall job using material white brick and red brick based on analysis of a contractor with the methodof 2017 SNI job and time of wall job white brick  and red brick per m2 using method Daily Record Sheet that is by direct observation and recording work time couples wall field. The result of the research conducted is found the cost of work required for couples wallwhite stone per m2 using analysis of contractor is Rp. 66.020,-/m2 and a pairof red brick wall is Rp. 75.020,-/m2. The cost of the work required for the pair of wall stone kumbung per m2 based on SNI method 2017 is Rp. 109.910,-/m2 and pair of red brick wall is Rp. 113.100,-/m2. After the comparison then it can be inferred that the couple wall using white brick cheaper than the pair of red brick wall, but the difference is not too significant is Rp 9,000,-per m2 with contractor method and IDR 3,190,-per m2using SNI 2017method. The time it takes to complete the job of couple wall using red brick per m2 is 0.445 hours/m2, whereas the time required on the job of couple wall using white brick is 0.324 hours/m2. So the job of  the couple wall using white brick more efficient 0.121 hours/m2 compared with red brick wall.

Abstract

Concrete is a mixture of concrete forming materials, namely: fine aggregate, coarse aggregate, cement, and water. Each concrete construction always be able to show its function, ie strength and endurance during the planned life. Therefore, in this research concrete treatment is known to increase the concrete but also need to know how long the concrete treatment is good Only requires water from the loss of water experienced. Thus the research is conducted to find out how much the influence of curing process uses sea water, PDAM sewage toward to the strength of concrete press. This research was conducted with the use of 3 types of water that is water PDAM, sea water, sewage. Cylindrical tests specimen with diameter 15 cm and height 30 cm. Each sample is made of 3 specimens by the age of 7 days. The value of compressive strength in PDAM water, seawater, sewage successively at the age of 7 days is 13,522 MPa, 8,759 MPa, 10,296 MPa. The value of compressive strength of Water PDAM at 7 days has increased compared to the compressive strength value of seawater and sewage, while the value of compressive strength of seawater has decreased compared to the rising sewage. So it can be concluded that the value of the highest compressive strength is water PDAM at the age of 7 days.
