Abstract

This analysis to determine the performance of the intercooler based on actual data, and the intercooler's performance against design specifications changes using the NTU method. Variable design specifications in the study are the number of plates, compressed area, and port diameter values from intercooler specifications provided by the company. The results of the inter-device performance analysis of compatibility with the specifications required by the company amounted to 99.40%. The results of the first trial of the tool specifications point the compatibility value to increase to 99.98% by increasing the number of plates from 79 to 150 plates, reducing the compressed area value from 0.47 to 0.2 m and increasing the port diameter value from 0.2 to 0,5 m. The results of the trial 2 tool specification showed a decrease to 86.51% due to changes in variable variables, by the number of plates to 25, raising the compressed plate width to 0.5 meters and increasing the port diameter to 0.6 m. The highest overall heat transfer value on May 23-24 is 346.225,37  based on actual data calculation of Intercooler effectiveness. The lowest overall heat transfer value is 346.213,29  based on data calculation it occurred on 22 May 2019.

Abstract

Light steel is one of materials that support the growth of construction technology at this time and it is generally used on roof truss contruction. The profile of light steel is a kind of steel profile which has dimension of thickness that is relatively thin with ratio of wide dimension of each profile element towards its huge thickness. In the assembling and installation, roof truss of light steel which is often encountered, cross section of C profile is connected by attaching body parts of two profiles or connecting wing parts with giving the connecting canal.This research uses the experimental method by flexural test with two points loading. The light steel which is used in this reserach is light steel of C profile by Ton Dong brand. The size is 75 x 35 x 0,75 mm andthe dimensions of beam frame specimenis 180 cm lengthand 25 cm hight, as many as 3 specimens with non centric profile overview. The research result shows that the average value of flexural strength is5,25 kNand the average of tensile strenght is 2281,67 N, while the result of experimental test uses UTM (Universal Testing Machine), the maximum strength is 5,92 kN and deflection 38,95 mm. The result of SAP 2000 analysis, the maximum deflection is 2,04 mm and 6 kN load. Keywords : Light steel of C profile, Light steel beam frame, Test of flexural stength.

Abstract

In general, the bridge type is a reinforced concrete bridge, composite and steel frame. The Baki River Bridge was originally a 40 m long Wood type bridge connecting the village of Mengkopot - Tanjung Pisang because the condition of the Baki river bridge has been damaged especially on bridge floors and girders due to age, so it is planned to re-use the steel frame bridge structure. By using the steel bridge structure, it is expected that later it can be a comparison for the future bridge planning.In this study, the structure of the planned bridge consists of bridge slabs, sidewalk slabs, backrest pipes, longitudinal and transverse girders, steel frames, wind ties, and joints. By following the SNI T-02-2005 bridge loading standard, SNI T-03-2005 for planning steel bridge structures and SNI T-12-2004 for planning concrete structures on bridges.From the planning results obtained thickness 200 mm Bridge Slab and thick sidewalk slab 250 mm with a longitudinal girder profile used WF 600.200.11.17 mm steel with a distance between girders 1.75 m. Transverse girders of steel profiles WF 700,300.13.24 are used with the distance between girders 5 m. Used Steel profiles WF 400,400.13.21 as Main Frame and Steel WF profile 150.150.7.10 as profiles for wind ties.‘Keywords: Steel frame, girder, connection,

Abstract

Management of construction projects is becoming increasingly complex due to the many parties that interact in it and the increasingly high demands for quality of functions, comfort, security, aesthetics and sustainability. Therefore construction management is needed to ensure the efficiency and productivity of a construction project in meeting various expectations and requirements. Contruction management analysis on this building project of Kinderfield School include volume measurment, RAB, cost recapitulation and working/occupation unit cost analysis, with use CPM method (Critical Path Method) is a method in identificating a stripe or working item critically. CPM method solves the problem with retreat and forward measurement. From the weight measurment occupation based on Barchart analysis, Curva S and building PDM scedhule of Kinderfield School needs the times as long as 42 weeks with cost estimation Rp. 9,439,526,000,00..Keyword: Barchart, Construction Management, CPM (Critical Path Method), S-Curve.

Abstract

The purpose of research : (1) determine the ratio between the combination of retrofitting tetrapod-bamboo alignment-tetrapod   (FP1); bamboo flow aligner-tetrapod-bamboo flow aligner (FP2); Check Dam Stones-Gabion-Check Dam Stones (FP3); Gabion-Check Dam Stones-Gabion (FP4)? (2) The effectiveness of the combination of strengthening the tetrapod-bamboo aligner-tetrapod   (FP1); bamboo flow aligner-tetrapod-bamboo flow aligner (FP2); Check Dam Stones-Gabion-Check Dam Stones (FP3); Gabion-Check Dam Stones-Gabion (FP4)?Using the experimental method by creating a Labolatorium scale river model. Testing using clay and sand. The test model is a cliff without reinforcement and cliff with a combination of reinforcement between tetrapods; bamboo flow aligner; check Dam stones and Gabions. Testing by flowing water for 180 minutes/3 hours with a constant discharge of 7.07 liters/second, the installation of reinforcement is 51 cm apart.The results showed that (1) In general, the effect of the FP1 reinforcement installation was the variation of the combination that was considered the best in reducing scouring on the cliffs and riverbeds. (2) Variation of the combination of FP1, is more effective in reducing the scouring that occurs. At the beginning of the channel turns from STA 00-06 effectively used tetrapod installation, with scours that occur as big as -5 cm, in the middle of the STA channel 06-16 effectively using the installation of bamboo flow aligner, scours that occur as much as -1.5 cm, whereas at At the end of the turn, STA 17-24 used tetrapod installation, scouring by -3.8cm.Keyword: scouring, bamboo flow aligner, tetrapod.
