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

STUDI PERILAKU CAMPURAN LATASTON (HRS-WC) DENGAN“LIMBAH KARET BAN LUAR” SEBAGAI BAHAN PENGGANTISEBAGIAN ASPALCandra Putra Kiswara 1& Andi Saiful A21&2Jurusan Teknik Sipil Fakultas Teknik Universitas Muhammadiyah MalangAlamat korespondensi : Jalan Raya Tlogomas 246 Malang 65144e-mail: candra_sum@yahoo.co.id, andiamal99@yahoo.co.idABSTRACTWaste to be one of the problems facing the nation at this time. Community is very disturbed bythe presence of various types of waste that is around their neighborhood. Ranging from industrialwaste to the waste home.The basic requirements of a road construction is to prepare the surface layer of a flat andstrong to ensure high security for a long time and the preservation of every detail in a variety ofweather. It required an asphalt mixture that is capable of supporting loads as well as capture thedamaging effects of traffic and the weather (climate) and can provide good service.With the addition of waste tire rubber is significantly affect mixture properties such Lataston(HRS-WC) Stability, Marshall Quontient, Flow and Air Voids. This is evidenced by the results oftesting using a Marshall. The average value of stability the average of 1220 kg. For Lataston (HRSWC)mix with additives outer tire rubber to rubber optimum levels (KKO) 11,50%, to produce amixture of qualities: Marshall Stability value = 1220 kg, Marshall Quotient value = 7,2 kN / mm,Value Air Marshall voids = 10,00%, Value Bitumen film thickness = 5,6 mm.Key Word: Waste Tire Rubber, Marshall Caracteristic
