Keywords: Composite Slabs, Foam Concrete, Shear Connectors, Slip Abstrak : Umumnya pelat lantai terbuat dari beton bertulang yang relatif berat, yang dalam pelaksanaannya membutuhkan cetakan (bekisting) dan penyokong yang relatif banyak untuk menahan beban selama pelaksanaan. Untuk mengatasi permasalahan di atas salah satu alternatif adalah dengan menggabungkan sistem precast dan cast in place yang biasa disebut dengan sistem komposit. Penelitian ini bertujuan untuk mengetahui perilaku lentur dari pelat lantai komposit beton busa akibat variasi jumlah shear connector, variasi mutu beton pengisi dan variasi tinggi atau tebal dari pelat lantai komposit beton busa. Pengujian yang dilakukan berupa pengujian lentur. Benda uji pelat komposit beton busa berjumlah 5 (lima) buah. Hasil penelitian menunjukkan kenaikan daya dukung dan lendutan maksimum pelat komposit dengan shear connector terhadap pelat komposit yang tidak dipasang shear connector masing-masing sebesar 127,5% dan 119,2%. Peningkatan daya dukung dan lendutan maksimum juga terjadi pada pelat komposit dengan mutu pengisi 117,95 kg/cm 2 dibandingkan dengan pelat komposit dengan mutu pengisi 95,30 kg/cm 2 masing-masing sebesar 110,22% dan 104,56%. Daya dukung dan lendutan maksimum pada pelat komposit dengan tebal 15 cm lebih besar dibandingkan dengan pelat komposit dengan tebal 12 cm yaitu sebesar 156.4% dan 102,4%. slip horizontal yang terjadi pada pelat komposit dengan shear connector lebih kecil 79% dari nilai slip pada pelat komposit yang tidak dipasang shear connector. Slip horizontal pada pelat komposit dengan mutu pengisi 117,95 kg/cm 2 lebih kecil 51% dibandingkan dengan slip horizontal pada pelat komposit dengan mutu pengisi 95,30 kg/cm 2 . Slip horizontal pada pelat komposit dengan tebal 15 cm lebih kecil 76% dibandingkan dengan pelat komposit dengan tebal 12 cm. Kata Kunci : Pelat Komposit, Beton Busa, Shear connector, Slip

Abstract : Generally slabs are made of reinforced concrete which is relatively heavy, that make it
requires many molds (formwork) and scaffolding to hold the load during the execution. To solve
the problem, one of the alternative is to combine the precast and cast in place which is known as
the composite system. This research aim is to get the information about the flexural behavior of the
foam concrete composite slabs due to variations of the numbers of shear connectors, variations of
concrete quality cast in place and variations of the height or thickness of the foam concrete
composite slabs. The testing on the specimens was done by giving the flexural loads. The testing
specimen of foam concrete composite slabs were made in 5 (five) specimens. The result showed
that the increasing of carrying capacity and maximum deflection of composite slabs with shear
connectors towards composite slabs without shear connector were respectively 127,5% and
119,2%. The increasing of carrying capacity and maximum deflection of composite slabs with filler
quality 117,95 kg/cm2 compared to composite slabs with filler quality 95,30 kg/cm2 were
respectively 110,22% and 104,56%. The carrying capacity and maximum deflection of composite
slabs with thickness 15 cm was bigger than composite slabs with thickness 12 cm that were 156.4%
and 102,4%. The horizontal slip that was occurred in composite slabs with shear connectors was
smaller 79% than slip in composite slabs without shear connector. The horizontal slip in composite
slabs with filler quality 117,95 kg/cm2 was smaller 51% than slip in composite slabs with filler
quality 95,30 kg/cm2. The horizontal slip in composite slabs with thickness 15 cm was smaller 76%
