Abstract

Damage to roads that often occurs can form cracks, holes, or the sagged;one of the reasons is lack of gradation of aggregate used in accordance with therequirements. The problem is that it is difficult to determine the appropriateproportion aggregate mix gradation in accordance with specifications and there is alack of understanding of the effect given to the characteristics of the mixture due tothe variation obtained in the range of gradation specifications. The research conducted is to examine the characteristics of the variation of theaggregate gradation value, to analyze the characteristics of Laston mixture resultedfrom aggregate gradation variations, as well as to determine the effect of variationgiven by aggregate gradation on the characteristics of the Laston.The test results show the characteristics values as follows. Variation 1: Stability isof 1123.87 kg (spec.>750 kg), flow 4.96 mm (spec.>2 mm), MQ 226.59 kg/mm(spec.>180 kg/mm), VMA is of 13.68% that is not meet specifications (spec.>15%),VIM 4.453% (spec. 3%-6%), VFB 67.87% (spec.>63%). Variation 2: Stability is of1135.37 kg (spec.>750 kg), flow 4.64 mm (spec.>2 mm), MQ 244.76 kg/mm(spec.>180 kg/mm), VMA 15.48% (spec.>15%), VIM 5.122% (spec. 3%-6%), VFB66.87% (spec.>63%). Ideal Gradation: Stability is of 1143.99 kg (spec.>750 kg),flow of 3.653 mm (spec.>2 mm), MQ 313.21 kg / mm (spec.>180 kg/mm), VMA16.48% (spec.>15%), VIM 5.901% (spec. 3%-6%), VFB 64.2% (spec.>63%).Variation 3: Stability is of 1160.58 kg (spec.>750 kg), flow 3.49 mm (spec.>2 mm),MQ 333.81 kg/mm (spec.>180 kg/mm), VMA 16.57% (spec.>15%), VIM is 6.06%which has not met the specification (spec. 3%-6%), VFB 63.44% (spec.>63%).Variation 4: Stability is of 1176.51 kg (spec.>750 kg), flow 3.18 mm (spec.>2 mm),MQ 370 kg/mm (spec.>180 kg/mm), VMA 16.81% (spec.>15%), VIM is of6.359% that has not met the specification (spec. 3%-6%), VFB is of 62.18% thathas not also met the specifications (spec.>63%).Base on the analysis of variance, Ftest value for each characteristic of mixture(stability = 13.67, Flow = 104.81, MQ = 73.705, VMA = 14.675, VIM = 4.5138,VFB = 1.352) is greater than the Ftable value ( = 3.48) with an error rate () used is5%, degrees of freedom treatment is 4 and degrees of freedom random is 10.

Abstract

This paper covers investigation which was carried out in the UnitedKingdom (UK), where utilization of waste materials in building industry had beenencouraged in line with the UK government strategy to reduce waste disposal tolandfill. The investigation was about building block named as Masonryblock, amasonry building block material that incorporates waste materials, namely steelslag, crushed glass, and coal fly ash, bound with bitumen (asphalt). The binder usedwas 50 pen bitumen. The materials were hot mixed, statically compacted thencured at 200°C for 24 hours. The main properties of the blocks evaluated werecompressive strength, creep and volume stability due to moisture and thermalexposure. It was found that the Masonryblock compressive strength wascomparable or even can exceed the compressive strength of concrete blockcommonly used in the UK (2.8-10 MPa), and can satisfy creep strain < 100microstrain. The volume stability of the Masonryblock was found affected bymoisture exposure. The samples expanded due to higher relative humidity and viceversa. On thermal exposure the samples expanded and the expansion was foundhighly reversible. The Masonryblocks gave coefficient of thermal expansioncomparable to clay bricks.

Abstract

In the SNI 03-1726-2002 Standard Clause 4.3.5 it is stated that “When astructural system parallel to the direction of nominal earthquake load, consists ofsome sub-structural systems, the representative reduction factor (Rr) of theearthquake load for this structure in the direction of the earthquake load can becalculated as an average of weighting values with each sub-structural system baseshear as its weighting factors”. With the representative reduction factor (Rr), thebase shear acting on the structure does not consider the weakest sub-system whichreaches its yielding capacity first, whereas base on stiffness concept, sub-systemwith a different ductility will resist a different base shear. In order to investigatedynamic behavior of a structure due to this both earthquake loading condition,analysis was done on a reinforced concrete structure of a regular building consistedof structural sub-systems of shear walls and frames which have each differentductility. This both loading conditions are the earthquake with reduction factor ofRr and Rs.Dynamic behavior of the structure is obtained from the results of modeling andanalysis of the structure using finite element software (SAP 2000). The calculationwas done in two stages in which the first stage, the structure was designed to resistboth gravity load and earthquake load. In the design process, earthquake load wastreated as static equivalent earthquake load with a reduction factor calculatedaccording to SNI 03-1726-2002 requirements. The second stage, the structure thathas been designed, its dynamic behavior was evaluated using nonlinear staticpushover analysis including period, base shear, horizontal drift, stiffness, dampingand other dynamic properties of the structures.The results of analysis show that dynamic behaviors of the structure subjected toearthquake load with representative reduction factor (Rr) differ from those of theearthquake load with reduction factor each sub-system (Rs). For earthquake loadwith reduction factor Rs, the actual ductility factor, actual earthquake reductionfactor, effective period of the structure are bigger than those of the structure withreduction factor Rr. However, it has smaller base shear, less number of plastichinges and smaller effective damping.

Abstract

In the implementation of construction projects, there is often adiscrepancy between the planned schedules and the work in the field, thus causingdelays. Many factors cause a delay, one way to anticipate is by doing theacceleration. In doing acceleration, cost and quality factors must be considered inorder to obtain the optimum cost and quality standards desired. Super VillaDevelopment Projects is selected for research studies because of delays in itsimplementation.Alternative acceleration used is the addition of working hours, from one hour tofour hours without any additional manpower. The calculation begins by finding thecritical path using Microsoft Project and then crashing is carried out to obtain costslope activities that are on critical path, then the analysis is performed using TimeCost Trade-Off Analysis. Finally, a graphic of the relationship between the costand the optimum time for each additional hour of work is created.From the analysis results, the optimum cost is obtained by adding one hour ofworks which reduce cost and time of Rp784,104.16 and eight days respectively,while the optimum time is obtained at additional two hours, with a reduction timeof 14 days and cost reduction of Rp700,377.35. This means that the acceleration with optimum cost is obtained when the addition is of one hour of work andoptimum time is obtained when the addition is of two hours of work.

Abstract

Optimisation of public transport use (such as angkot or microbus) isrequired due to the difficulty to increase the roadway capacity by widening of roadin order to manage supply. Therefore, an alternative approach is required bymanaging transport demand so that the system can be controlled. This approach isrequired especially for the new developed housing in Dalung Village, BadungRegency. Dalung area (in North Kuta District) is part of Samigita developmentproject where the the number or people travelling to work are about 613 persons(189 persons working in public service and 424 persons in private company). Themajority of people in this area are travelling by private vehicles. One aspect thatneeds to be studied is the general cost for the journey to work both by privatevehicles (motor bikes) and public transport. Mode choice model used is BinomialLogit Model. The model equation is Log {(1 – PP ) / PP} = 2,248 – 0,001 (CP –CU). Results of analyses indicate that if the cost difference between publictransport and private transport increases, the probability of using private vehicleswill increase; Although the cost of the two modes of transportation is set at the samecost, the majority of workers will still use private vehicles (about 79%), and thisis also the case even when the cost difference is Rp 2.800,00. The cost balance between private vehicles and public transport is achieved when thecost of using private vehicles is about 1.4 times more than public transport cost.

Abstract

Badung Regency, especially South of Badung is the center of tourism inBali where development of shopping centers increases. The existence of theseshopping centers as one of commercial facilities has attracted trips which cause theincrease of traffic volume, degree of saturation, and conflict between through andlocal traffic. Therefore, a study on the amount of trips attracted to these shoppingcenters is required. The objectives of this study are to evaluate trips mode compositionand to model trip attraction to shopping centers. The primary data were obtainedfrom trip attraction survey whilst the secondary data were obtained from theadministration of the shopping centers (i.e. total area, floor area, parking area,number of employments, and number of supporting facilities available). The resultsof analyses on customer mode split indicated that the proportion of using motorbike was 58,43%, 41,37% light vehicle, 0,10% heavy vehicle and 0,10% unmotorisedvehicle. Multiple regression analyses indicated that independent variablesthat influence trip attraction on peak hour are total area (X1) and parking area(X2). For one day trips, only total area had a significant influence. Trip attractionmodel for morning peak hour, evening peak hour ad for one day trips are: Y11 =105,747 + 0,005 .X1 (R2 = 0,967); Y12 = 45,601 + 0,015 .X3 (R2 = 0,984); Y13 =3405,73 + 0,187. X1 (R2 = 0,920), respectively.

Abstract

A study was carried out to analyse the daily solid waste generation in thedistrict of Kuta and to determine the number of trips required transporting thewaste to the final disposal site (TPA) in Suwung for the year of 2009, and itsestimation until 2015. Data required for the study was collected from on-sitesurveys and other relevant institutions. The study analysis was based on methodsderived from the Indonesian National Standard (SNI) and US EnvironmentalProtection Agency.The study shows that the district of Kuta generated 272.89 m3 solid waste per dayin 2009. The solid waste transportation to the final disposal site (TPA) in Suwungis carried out using stationary container system/SCS and hauled containersystem/HCS. By maximizing the use of the existing solid waste collection trucksowned by DKP Badung Pangkalan Kuta, i.e. the municipal waste managementinstitution for the Kuta District, the transportation to the TPA requires 34 trips/dayof SCS, supplemented by 2 and 3 trips/day of HCS for container sites at Jl. PuriGerenceng, Tuban and Pasar Kuta Unit II respectively. In case no 3R-policy forsolid waste management is adopted, the solid waste generation in 2015 is predictedto be 501.89 m3/day. Considering that no more solid waste container location isprovided, it would be necessary to increase the number of trips using SCS methodto 67 trips/day.
