The research was conducted to investigate the performance of old repaired columns inSriwulan Village (Sayung) and Pucang Gading. The performance of 3 columns wasinvestigated by non destructive test and destructive test at age of repaired columns at 12, 13,and 14 months. Non destructive test conducted by Hammer Test while destructive testconducted by Core Drill Test. The results of research has shown that from Hammer Test,highest compressive strength at age 14 months was 45,65 MPa. For Core Drill Test results,the highest compressive strength 73,62 MPa found in Pucang Gading at column 1 at zone A byage 14 months while the lowest at same site and column at zone C 14,22 MPa

Precast material is a user-friendly construction product. One innovation that is being developed is sandwich concrete. Sandwich concrete is composed by skin layers, that are strong and stiff, and lightweight concrete as core layer. As a part of builiding construction, each structural and non-structural element resists load in certain time. The purpose of this research is to investigate creep performance of concrete sandwich beam. By observing the effect of creep, it can be known the long-term effect due to the constant loading on a material. The test specimen is formed of sandwich construction beam, with its core layer consists of lightweight concrete and styrofoam (cement EPS sandwich panel) mixture. This research conducted with two kinds of size and proportions of specimen, single beam (length=100 cm; width=20 cm; thickness=7,5 cm)and double beam (length=100 cm; width=20 cm; thickness=7,5 cm)which is a combination of single beams glued together with Sikabond. The loading method that used in this research is third point loading as described on ASTM C393 in two positions, horizontally and vertically. After having loaded of 3 kN in 2 hours, each test specimen has deflected and gives creep strain value. The values of creep strain are: specimen RH-S01 by 3,23%, specimen RV-S03 by 0,40%, specimen RH-D03 by 0,60%, dan specimen RV-D02 by 0,32%.The smallest value of creep strain obtained by double beam that was tested vertically, due to have greater EI value than the horizontally tested specimens. According to the maximum deflection and load that can be resisted by the specimens, sandwich concrete shall not be recommended for structural beam. This research shows that the creep effect of constant loading by 3 kN for 2 hours on sandwich concrete beam is not secure

The resesearch used amylum as a modified polymer and honey as its added ingredient. Therewere with 3 compositions with honey, 0%; 0.03%; and 0.3%, and also 6 amylum compositions,0.1%; 0.2%; 0.5%; 1%; 2%; and 5%. The number of specimens with 20 cm in length and 10cm were 270 that were tested for compressive strength, and the number of specimens with 30cm length and 15 cm in diameter were 90 that tested for splittingtensile strength. The resultsof this research met conslusions: (1). Optimum compressive strength achieved by specimenKT-M0,03-G with 0,03% honey and 0,5% amylum of cement weight; (2) Optimum splittingtensile strength achieved by specimen KTB-M0-A with 0,% honey and 0,10% amylum of cementweight;

This study is based on traffic accidents in Indonesia which increased from year to year, theincrease of the accident rate resulted in the loss of material or casualties. Frequent accidentsare classified as blackspots (accident-prone points). Then to minimize the blackspot, there is aneed to study the safety of traffic more deeply, one of the efforts is to conduct a road geometricreview. In the geometric overview of the highway there are horizontal alignments and verticalalignments as the main points of discussion, where horizontal alignments discuss the speed,bend length, stop visibility, side free areas, bend extension and super elevation. While thevertical alinemen discuss about the cleverness, and vertical arch. Analysis of horizontalalignment and vertical alignment based on RSNI 2004 criteria. The results of this study indicatethat there are some discussion of horizontal alignment and vertical alignment that is not inaccordance with the criteria of RSNI 2004, the discussion includes the length of the curve, thestop visibility, and the side free area for alinemen horizontal, and vertical curvatures andvertical alignments.

The research aimed to observe durability of sandwich concrete block with styrofoam inaggressive environment which was modeled by curing media. The curing media used in thisresearch are plain water, sea water, brakish water, and tidal flooding water. The curing wasconducted for 28 days and followed by compressive strength test. The result of this researchfound that maximum compressive strength was 1,76 MPa with tidal flooding water as curingmedia, followed by 1,67 MPa with brakish water as curing media, and also 1,64 MPa with seawater as as curing media, and the lowest compressive strength was 1,36 MPa with plain wateras as curing media.

Shringkage is a volume change unrelated to the load, where the volume of concrete is reduceddue to reduced water content due to hydration or evaporation or evaporation. The objective ofthis research is to obtain the shrink parameter on sandwich block with Styrofoam stuffing inthe form of visual, damage, saturated and shrinkage in the medium of marine and freshwatersoak for 28 days and get the graph between time and depreciation. This research uses twoexperimental method that is by way of oven and not dioven in fresh water and marine waterimmersion media, each of which is submerged media in the form of 5 pieces of specimen length37 cm, width 15,5 cm, and thickness 7.5 cm which if in total amounted to 10 concrete blocks,the concrete block is tested in laboratory materials Soegijapranata Unika by using thecontainer as a medium of immersion media and the length of the sorong as a tool length, width,thickness of the block and the scale that has a precision of 0.1 for get the weight of the concretethen if it gets the result will result in the amount of shrinkage. The results obtained from theshrinkage will be concluded whether the sandwich panel with Styrofoam stuffing can be usedas a bearing wall.
