Abstract

Pavement recycling is one of resources conservation and preservation methods. Using of Reclaimed Asphalt Pavement (RAP) can give contribution to pavement quality because its quality reduction possibility due to over load of vehicle in lifetime service. For that reason, RAP physical properties research would be taken. This research using aggregat and bitumen which is come from RAP extraction. Aggregat testing such as Impact Value (AIV) test, Aggregat Pressure Value (APV) test and Spesific gravity test. Bitumen testing are penetration test, softening point test and  Spesific gravity test. According to the research result, was found that RAP aggregat can be used as a pavement material. The fact can be figure out from AIV value is about 6,6% and ACV value is 20,4%. Otherwise RAP aggregat gradation is not fulfill the specification, so that gradation modified must be taken. RAP bitumen testing showing that penetration value is 21,6 dmm and softening point value is 57°C. It means that adding modifier or rejuvenating agent is necessary to do to increase quality of RAP bitumen   Keywords: RAP aggregate, RAP bitumen, recycling

Abstract

Beam and plate are dominant element of a reinforced concrete building which experience pressure and flexural moment due to gravity which are live and dead loads. This research aims to find out the value of flexural capacity of reinforced concrete beam using coconut shell as coarse aggregate. The laboratory test results and the theoretical result were compared. In this research, beam of 175 x 350 x 1400 mm were used, the identical push-load used were 2 D 5,6  mm and variation of the number of tensile reinforcement were 4 D 7,8 mm; 5 D 7,8 mm, and 6 D 7,8 mm. Each variation is presented in three samples. Hence, resulting different maximum loads.The result obtained as concrete unit weight, which are 1,773 gr/cm3, push-load strength of 13,59 MPa, average flexural capacity of 95 kN for BL 41 to BL 43 and 115 kN for BL 51 to BL 63. The result of flexural capacity of BL 51 to BL 63 was not fully reached due to incompetency of the testing instrument.   Keywords: flexural capacity, beam, coconut shell concrete

Abstract

Palu Grand Mall construction project is a large-scale construction projects that use different types of materials with large amounts. Therefore, the planning and control of the appropriate material to be very important. The purpose of this study was to determine how the   process of planning and control of material and to determine the size of the procurement quantity of material from the two methods of inventory control consists of methods Lot For Lot and Economic Ordering Quantity method that provides the most optimal total costs in construction projects Palu Grand Mall. The method used in this thesis is descriptive photograph and methods Material Requirement Planning (MRP) consist of methods Lot For Lot (L4L) and the Economic Ordering Quantity (EOQ). The results revealed that, in the process of planning and controlling materials on construction projects Palu Grand Mall is the starting material requirements planning, material selection and proceed with the selection of suppliers of materials. Once that is done the booking and purchase of materials. Then the material receipt and storage of materials. The last process in the release of material to the construction site. Planning material procurement inventory control method provides a theoretical optimum total cost of inventory is a combined method of EOQ method and method L4L. The measure of the quantity of material procurement is a 5066 D19 iron rod, iron rods Ø10 number 58 591, iron rods D22 number 6638, beam 5/7 number 415 m3, and multiplex sheet 2903 with a total cost of inventories of Rp3.488.366, -.   Keywords: material, process planning and control, MRP

Abstract

Physical and mechanical properties of uniform sand (Siuri sand) mixed with fine grains is not the same as pure uniform sand, and the void ratio (e) can not be considered as appropriate index to describe the microstructure changes due to the fine grains. Thus, the use of intergranular void ratio is recommended for the condition of fine content less than the threshold fine content (FC <FCth). In this article, the primary data were obtained by conducting laboratory tests, by testing the physical and mechanical properties of the mixtures. Tests were carried out on pure Siuri sand (0%), pure non-plastic fines (100%), and the mixtures with fine content variations of 10% - 90% (by weight of mixture), however, the discussion were focused on dominant coarse grain conditions which was pure Siuri sand (0%) and the mixtures with non-plastic fine composition varied as 10%, 20%, 30% and 40%. The results show that the changes in content of non-plastic fines combined with Siuri sand showed characteristic changes in a similar pattern both in physical and mechanical properties. Fines addition to Siuri sand had increased the value of some parameter (gd, gdmax, gdmin, f, dan t) and had decrease some other parameter (e, emax, dan emin) up to the 30% fine content, then the opposite occured in 40% fine content. When fine content had exceed threshold fine content (FCth) which were between 30-40%, it showed a behavior transition, from behavior of higher contribution of sand in the mixture (dominance of sands) to higher contribution of fines (dominance of fines).   Keywords: void ratio, intergranular void ratio, shear strength, Siuri Sand

Abstract

District of Lamala Regency of Luwuk is the area in which shortage of  water and difficulty in supplying the water needs of its population. This planning study aims to address the fresh water problem and determine the needs of fresh water , especially three villages in the District of  Lamala namely village of Bonebabakal, Lomba and Poroan.The study was conducted by collecting primary data and secondary data, as well as direct observation in the field. Furthermore, to drain the water from the spring water to the deposition basin of 20m3 and reservoir basin of 50m3 at a service area with a distance of 3 km from the source and height difference of 128 meters can utilize the force of gravity. From the research, the spring discharge data obtained at 20.1 liters / sec and to meet the needs of local water services up to year 2031 the population projection can be calculated using the arithmetic and geometric methods.As a suggestion to optimize the volume of water , it should be made on the fresh water catchers building in the location of  water springs as well as the manufacture of bags to drain the sediment sludge coming from the spring.   Keywords: depositional basin, reservoir, springs

Abstract

Earned Value method (EV) has several weaknesses which makes it difficult to optimally apply in the construction projects. This study aims to identify the shortcomings of Earned Value related to the project cost and time performance. Literature study was conducted from the various sources related to the EV topic. The result shows that the main weakness of Earned Value method are: EV prediction method is assumed deterministic, linear, non-dynamic and does not accommodate uncertainty factors of time and cost of construction projects.   Keywords: construction  project, time and cost performance, earned value

Abstract

This study aims to provide an overview of the development planning of water distribution networks in the village of  Patutuki District   of   Peling Tengah,   considering   the region located in the coastal areas with limited of surface water sources, moreover the constriction and leakage in pipelines and water quality containing calcium or poor maintenance, so  the  flow  of  water  to  the  consumer  is reduced.  The scope  of study  is limited  to the analysis  of the availability  of water  discharge mainstay  as  one  of  the  water  sources  in  the village  Patutuki  using  FJ.  Mock  and  calculate the   domestic  water   supply   in   the   village   of Patukuki  District  of  Peling Tengah  depended on the number of  population. Furthermore, network planning distribution of domestic water in the service  area by gravity  through  the branching  system  and  closed  pipes.  For secondary data collection was carried out in the form  of meteorological  data,  population  data, topographic  data  and  the  data  of  land-use. Then calculate the water needs to be compared with the discharge  mainstay. The result is the minimum river discharge mainstay of Bebek River which is the main water source to meet water  needs in the area of service to 20 years .The maximum pressure meets the maximum permissible  limit  of 10 kg/cm2 and also meet the maximum  speed limit is a maximum  of 3 m3/sec.  For  the required  number  of plumbing needs in this plan that HDPE pipe ø 102 mm by 108 rods , PVC pipe ø 102 mm 33 rods , PVC pipe ø 76 mm 557 rods , and PVC pipe ø 51 mm 749 rods.   Keywords: water distribution networks, domestic water, Peling Tengah
