Abstract

Abstract: This study investigates the influence of household income on both car and motorcycle ownerships in the city of Denpasar using a Multinomial Logit Model. The household income is about 61%, 17% and 61% more likely to influence a household owning 1 motorcycle and 1 car, 2 or more motorcycles and 0 car, and 2 or more motorcycles and 1 car respectively than 1 motorcycle and no car. The probability of both car and motorcycle ownerships increases substantially by more than 4% in the next 20 years if household income in Denpasar city rises. This is particulary applied for the household owning 1 motorcycle and 1 car and 2 or more motorcycles and 1 car. The probability of a household owning 1 motorcycle and no car ownership however, drops significantly by almost 10% in the next 20 years if household income in Denpasar city increases. Consequently, the household income significantly influences both car and motorcycle ownerships in the city of Denpasar. A huge number of car and motorcycle uses on the road continously leads to serious transport problems in the city of Denpasar for the next few years. This is related to the negative impacts of transport in particular road safety and environmental impact. Improving the existing public transport and introducing a high quality public transport service within and to/from Denpasar city is urgently required. The fare of such high quality public transport service in Denpasar city however, must be sufficiently low to compete with the cost of riding a motorcycle. In addition, a significant amount of fare subsidy from both local and central government is considerably required

Abstract

Nusa Penida Island-Klungkung besides has beautiful views as touristdestination, it also has a potential materials for building and pavement constructionsfrom the large scale of rock lime stone that spreading out on its area. Themain objective of the research is to find out the physical characteristic ofaggregate and its qualities if it meets the Bina Marga Standard. The sample ofrock lime stones were crushed on Aggregate Crushing plan at PT. Sumber AlamKarisma Jaya. The method of descriptive comparative analysis was applied. Thesieve analysis results show that both medium and fine grading coarses fulfill thestandard requirement of Bina Marga, although the coarse aggregate tends tocoarsest. The physical characteristics of Nusa Penida Lime stone namely the bulkdensity was between 2.4 – 2.5 gr/cm3 and the specific gravity was between 2.54 –2.6 gr/cm3, in the range of Bina Marga Standard. The absorption was in the rangebetween 1.77 % and 2.7 % which is less than the standard of 3%. The abrasionresult was of 27 % that is better than Bina Marga Standard of 40%. It is clearlyseen that the Nusa Penida rock lime stone can be used as construction andpavement materials.

Abstract

Abstract: Behavior analysis and performance evaluation of frame structures with infilled wall (RDP) has been done by making four structure models, a model of open framework (MOF) and three RDP models (M1, M2, and M3). In the RDP models, walls in transverse direction of the building was placed fully on the floor 2, 3 and 4, and varied on the ground floor. The wall in longitudinal direction, however, was not included in the model because of the holes and irregularity. The walls on the ground floor were placed fully for M1, at the ends and middle of the building for M2, and none for M3. The walls were modeled as 3 diagonal struts that can withstand compressive stress only. The behavior of the structure was observed through linear elastic analysis by comparing story drift and its ratios, while the performance of the structure was evaluated through nonlinear static Pushover analysis using SAP2000. The analysis showed that the inclusion of infill walls in the model increases the stiffness of the structure. The values of drift at roof level were 8 mm, 10 mm, 12 mm and 28 mm for M1, M2, M3, and MOF, respectively. Soft story mechanism was detected in the RDP models with irregular wall placement with maximum drift ratio of 157% and 249% for M2 and M3, respectively, while MOF and M1 with continuous wall have drift ratios of 101% and 92%. Discontinuous walls also decrease performance of the structure. Pushover analysis results in the transverse direction showed that M1 is capable of resisting the largest base shear force 658 tons with a level of performance Operational (O), while M2 with O performance levels capable of resisting base shear of 437 tons. M3 and MOF can resist the lowest base shear force of 270 tons and 279 tons with performance level of Immediate Occupancy (IO) and Life Safety (LS). Pushover analysis in the longitudinal direction of the building (where the wall was not modeled) showed that, MOF can resist the least base shear compared to the three RDP models. This suggests that the struts on the transverse direction also affect the stiffness of the structure in the longitudinal direction. The actual value of ductility in the transverse direction of the structure are 4.6; 2.9; 2.8; 3.4; for MOF, M1, M2 and M3, respectively. While in the longitudinal direction the ductility are 3.2; 3.6; 3.8; 3,9. All models ductility values are smaller than the design value, i.e., µ = 5.

Abstract

Flowing water by pipe is mostly used to distribute the water from itssources to taps for various needs. On the way of distribution, it meets some obstacles,i.e.: velocity, surface and roughness changing. Thus, the research has been done inorder to know the influences of all the changes of the head loss on the 1 meter pipe.This research used Fluid Friction Apparatus complete with hydraulic bench andmanometer. Variation of flowing on pipe has done for 50 times, using each 6 mm and10 mm and four 17.5 mm pipe with different roughness which consist of differentsands diameter.From that research we found out that there’s a similarity in velocity and roughnesswith head loss showing polynomial order 2 ( hf = a + bu + cu2 and hf = a + bk + ck2 )where much velocity and roughness causing higher head loss. While pipe surfaceinverse proportional to head loss that shows exponential relationship (hf = a e –bA)where more surface causing less head loss.
