Abstract

Karmila Achmad1, Agoes SMD2 & Tavio31Mahasiswa Program Magister Teknik Sipil Struktur Universitas Brawijaya, Malang dan Dosen Politeknik NegeriBalikpapan2 Guru Besar Teknik Sipil Struktur Universitas Brawijaya, Malang3Dosen Teknik Sipil Struktur-FTSP Institut Teknologi Sepuluh Nopember, SurabayaEmail : milabpp@yahoo.co.idABSTRACTThe aim of this research is to get improving of strength and ductility in column specimen giventhe GFRP strengthener (Glass Fiber Reinforced Polymer) toward with original column, by using thecyclic load as the fix representative of quake load. There are two specimens full scale used. Theyare C-1 (original column) and C-1G (column with GFRP strengthener 1 layer). From the researchgot Pmax sequentially is 278,9 kN and 372.4 kN, and dmax is 53.24 mm and 56.78 mm, each for C-1and C-1G. For C-1 column, the concrete gets damage in plastic hinge zone at drift ratio 3.5%indicated by bending of longitudinal steel bar and spalling of cover concrete. The test for C-1G endsin third cycle at drift ratio 5% and gets damage in fracture of GFRP in plastic hinge zone. Thedamage is the changing of resin color the circumferential direction in three spots. They are as longas 10, 11 and 18 cm. Ductility index taken on three positions are plastic hinge zone, column with ahalf high effective and as high as effective column. From the analyze result got ductility index C-1on the three positions are 1.65; 1.70; 1,97 and ductility index C-1G are 1,44; 1,44 and 1,38 each forplastic hinge zone, a half high effective and as high as effective columnKey words : ductility, GFRP, strength, external confinement, cyclic

This research uses survey research conducted at contractorcompanies in Malang. The population in this study is the management of the contractor as theproject manager supervisor leader contractor (director) or authorized by the company. Primary datawas collected through questionnaires. Secondary data obtained from the literature to form iteratur,journals, and data from agencies with an interest in this study, such as professional associations andrelated agencies.The results of descriptive analysis using respondents’ answers showed knowledge variable,variable skills, attitudes and behavior / work commitment, top management variables on averagehave an important influence to determine the success of the project. Test results using regressionanalysis and test assumptions Multiple Linear Regression analysis shows simultaneously betweenthe variables of knowledge, skills, work commitment and top management significantly influencethe success of the project amounted to 0.831. Partially between the variables of knowledge, skills,work commitment and top management significantly influence the success of the project amountedto 0.286, 0.296, 0.280 and 0.147.Dominant variable affecting the level of success of a project is a skill / expertise.Keywords: Competence, Project Manager, Contracting Company

Moch. Sholeh1 & Dandung Novianto21 & 2Fakultas Teknik Jurusan Teknik Sipil Politeknik Negeri MalangABSTRACTClay consists of grains - grains are very small (<0002 mm) and shows the nature - the natureof plasticity and cohesion. Cohesion indicates the fact that part - the part that is attached to eachother, while the plasticity is a trait that allows the form of the material was changed - edit withoutchanging the content or without returning to its original form, and without any cracks or brokens.And clay with high plasticity index has strong support low when used as a basic foundation of thehighway, so the need for soil improvement.From the above problems then this study aims to engineer clay with red brick powder in fourcomparisons. The first native land. Both the original soil mixed with red brick powder 5%. The thirdnative soil mixed with red brick powder 7.5%. The four original soil mixed with red brick powder10%. Each of these sought specific gravity, liquid limit, plastic limit and plasticity index on theoriginal soil, mixing 5%, 7.5% and 10%. From the analysis of data obtained the following conclusion:the original soil, the value amounting to 60.9 Liquid limit, plastic limit values of 42.8 and plasticityindex value of 18.1. The most optimal additional percentage is 7.5%. And Plasticity Index value at7.5% is 20,31.Key words : Red brick powder, Soil Stability, Subgrade and the Road

Rini Febri Utari1 & Andi SA21&2Jurusan Teknik Sipil Fakultas Teknik Universitas Muhammadiyah MalangAlamat Korespondensi : Jalan Raya Tlogomas 246 Malang 65144email :rynfu_sheara@yahoo.co.idABSTRACTThe need of housing in Indonesia is estimated annually by an average of 800,000 new housingunits per year, the state saw a lot of developers that have sprung up to provide homes. But thechallenges that are often faced by the housing developers is to formulate the type of house that willbe produced so that it meets the constraints like aspects of the market, the area, production costs,comply with government regulations as well as the maximum profit margin. The purpose of thisstudy is to formulate the composition of the type of house to be built so as to achieve the optimumsolution and maximum profit.Optimization method used is the simplex method. As the object of study is the housing ArayaBumi Megah Malang, especially Cluster GreenWood Golf with a land area of 100.000m2. Type ofhouse that will be built is the type X1 (45/130) with Rp.389.750.000 price per unit, type X2 (54/170)with Rp.505.200.000 price per unit , the type of X3 (61/162) at a price of Rp.514.200.000 per unit,type X4 (65/144) with Rp.550.500.000 price per unit, type X5 (77/162) with Rp.609.500.000 priceper unit, type X6 (96/180) at a price Rp.720.500.000 per unit, the type X7 (141/144) withRp.833.100.000 price per unit, type X8 (161/162) with Rp.918.625.000 price per unit , the type ofX9 (221/200) with Rp.1.148.500.000 price per unit and the type X10 (308/375) at a price per unitRp.1.654.500.000. Function objective of this research is to gain maximum restriction function island area, limits cost of production and the market demand aspect.The analysis showed that the optimum combination type number built is X1=0, X2=0, X3=0,X4=387, X5=0 , X6=99 , X7=95 X8=0 X9=64 X10=0. So that from the ten types offered are only fourtypes produced the type X4 (65/144) of 387 units, type X6 (96/180) by 99 units, the type X7 (141/144) 95 units and the type of X9 (221/200) by 64 units to obtain the maximum profit ofRp.78.483.073.000.Key words : Optimization , Simplex Method , Number of housing types
