Abstract

Productivity is an important factor in determining the success of a construction work. Increased productivity will reduce work time, and that means it will reduce costs. In general, the value of productivity is determined by the factor of the volume of work, implementation time, and the number of workers. In order to get the job done well, a planning effort is needed by paying attention to these factors. For this reason, this study was conducted to determine the value of productivity in one component of building construction work, namely lightweight steel roof truss work. The object of study was the work of lightweight steel roof truss 4 (four) project sites, namely the 4 x 25 Shop Houses Construction Project in Meulaboh, West Aceh, the Building of the Rector & Administration Bureau Building of STKIP Bina Bangsa Getsempena Banda Aceh, the Construction of the Getsempena Lhoksukon North Aceh STIKES Building and the Construction of North Aceh RIKI STIKes Building, Bina Nusantara Idi, East Aceh. The roof truss material used is type C Truss 75 0.75 Thickness. The volume of roof truss work is planned to be 2022.38 m2. The study was conducted through field observations by directly recording the volume of work, the duration of each stage of work, and the number of workers involved. The results of the analysis show that the productivity value for roof truss works is obtained by an average of 2,062 m2 / hour or 16,499 m2 / day. In the implementation of roof truss work, the amount of labor used is the same in all segments, so the value of productivity tends to be determined by the magnitude of the ratio between the volume of work and the effective time of implementation. Thus, if the amount of work volume can be completed in a shorter time then the value of productivity will increase

Abstract

Water is a natural resource that is very useful in human life. One of the problems that occurred in Kabupaten Aceh Tenggarat, precisely in the city of Kutacane and especially in Kecamtan Babussalam, is the reduced water discharge from the Lawe Sikap river which has been the source of water for the Lawe Sikap PDAM Water Treatment Installation. The aim of this research is to find out the existing clean water distribution piping network system, then an effective alternative piping network system will be planned. The method used in this research is secondary ftom the existing network system. The research of network analysis is using the Pipe Flow Expert program. Evaluation of the existing network using PVC pipe sizes used 4'', 8'' and 12'' diameter, the existing flow velocity is 4.989–7,893 m/sec, exceeds the allowable limit of 3.0–4.5 m/sec and the pressure is still minus. So, the results obtained from the research plan using PVC pipe sizes used are 4 ", 6", 8 "and 12" in diameter. From this research also obtained the results that the flow velocity is 4.004 m/sec and is still within the permitted limit and the pressure is still minus. Based on the results above, it can be concluded that the existing network must be re-planned. The suggestion that the author can give to produce a sufficient pressure is to use a pump system

Abstract

Adding salt to the original soil can reduce the optimum moisture content and increase the maximum dry volume weight at a percentage of 0% by 0.8913 gr / cm3 - 10% by 1.0593 gr / cm3. CBR testing that is not submerged in the original soil will improve the mechanical properties of the soil if mixed with 5% of 8.37 kg / cm2, then a decrease of 10% is 3,297 kg / cm2 and so on because it is easy to dissolve and has low bond strength. So, the CBR shows that its value decreases dramatically as the percentage salt increases. Testing the value of the shear angle (Ø) also continues to fall with increasing value of the percentage of Salt. In cohesion testing also increased at 5% by 0.089 kg / m2 and decreased if the percentage of salt addition increased. The value of shear strength also increased at a percentage of 0% by 26.57o - 10% by 39.29 and decreased at a higher percentage. The addition of salt to native soil can also increase the shear strength value of 5% salt by 0.209 - 10% salt by 0.351 kg / cm2 and decrease at 15% higher salt addition by 0.140kg / cm2.
