ABSTRAK
Bentuk profil speed bump yang tidak sesuai dapat membahayakan pengguna jalan yang melintas. Penelitian ini berfokus pada pembuatan profil
speed bump dari material concrete foam dan polymeric foam yang diperkuat serat TKKS agar diperoleh desain stuktur speed bump yang lebih baik dan lebih aman sesuai standar. Tujuan penelitian ini adalah menganalisa respon mekanik produk
speed bump polymeric foam diperkuat. Serat Tandan Kosong Kelapa Sawit (TKKS) yang dikenai beban impak jatuh bebas. Manfaat penelitian ini untuk memanfaatkan serta mengolah Tandan Kosong kelapa Sawit (TKKS) hasil pabrik kelapa sawit agar dapat bernilai ekonamis. Metode yang dilakukan adalah metode penelitian eksperimen. Data diperoleh melalaui pengujian impak jatuh bebas pada
speed bump dari bahan concrete foam dan polymeric foam. Pembuatan speed bump menggunakan mortar; semen 26%, pasir=38%, air=28%. Lalu ditambahkan bahan pengembang=5%. Bahan concrete dan rongga 1”,2” dan 3” inci diberi matrik berupa serat TKKS=3%. Dimensi speed bump 200 × 400 × 150 mm. Pembuatan polymeric foam menggunakan bahan; blowing agent=20%,
resin=60%, serat TKKS=10%, katalis=10%. Kesimpulan penelitian ini; dari uji impak jatuh bebas terhadap speed bump yaitu, Pada ketinggian 2 m speed bump
datar concrete foam; spesimen satu F max= 132,398 N, dan Tegangan=0,066199 MPa Spesimen dua F max= 142,198N, dan Tegangan= 0,071099 MPa. Pada ketinggian 2 m posisi speed bump datar rongga 1 inci; spesimen satu F max= 44,1 dan Tegangan = 0,02205 MPa. Spesimen dua F max= 51,94 N, dan Tegangan= 0,02597 MPa. Pada ketinggian 2 m posisi speed bump datar rongga 2 inci spesimen satu F max= 20,58 N, dan Tegangan=0,01029 MPa. Spesimen dua F max= 19,6 N, dan Tegangan= 0,0098 MPa. Pada ketinggian 2 m posisi speed bump datar rongga 3 inci spesimen satu F max= 97,188 N, dan Tegangan 0,048559 MPa. Spesimen dua F max= 88,2 N, dan Tegangan 0,0441 MPa. Dari pengujian impak jatuh bebas concrete foam dan rongga 1”,2” dan 3” inci terjadi keretakan.

ABSTRACT
Profile shapes speed bump that does not comply could endanger road users passing. Thisstudy focuses on profiling speed bump of foam concrete material and polymeric foam-fiber reinforced TKKS order to obtain a speed bump structure design better and safer standard. The purpose of this study was to analyze the mechanical response speed bump polymeric foam products strengthened. Fiber Oil Palm Empty Fruit Bunch (EFB) is subjected to impact loads in free fall. The benefits of this research to utilize and process the palm oil Empty Fruit Bunch (EFB) results of palm oil mill to be worth ekonamis. The method used is the method of experimental research. Data obtained melalaui impact testing on a free fall speed bump of foam concrete materials and polymeric foam. Making speed bump using a mortar; 26% of cement, sand = 38%, water 28%. Then added material developers = 5%. Concrete materials and cavity 1 ", 2" and 3 "inch by matrix in the form of fibers EFB = 3%. Speed bump dimensions 200 × 400 × 150 mm. Making use of polymeric foam materials; blowing agent = 20% = 60% resin, fiber TKKS = 10%, catalyst = 10%. The conclusion of this study; of free fall impact test against a speed bump that is, At a height of 2 m flat speed bump foam concrete; specimens of the F max = 132.398 N, and Voltage = 0,066199 MPa Specimen two F max = 142,198N, and Voltage = 0.071099 MPa. At a height of 2 m flat speed bump position of the 1 inch; specimens of the F max = 44.1 and Voltage = 0,02205, specimen two F max = 51,94 N, and Voltage = 0,02597 MPa. At a height of 2 m position flat speed bump cavity 2 inch specimen of the F max = 20.58 N, and Voltage = 0,01029 MPa. Specimens two F max = 19.6 N, and Voltage = 0.0098 MPa. At a height of 2 m position flat speed bump cavity 3 inch specimen of the F max = 97.188 N, and Voltage 0.048559 MPa. Specimens two F max = 88.2 N, and Voltage 0.0441 MPa. Impact testing of foam concrete free fall and the 1 ", 2" and 3 "inch cracks occur.
