Abstract

The development of technology in the field of materials and construction produces many innovations, one of them is sandwich plate system. Sandwich plate system is a material formed by two different materials into one layer. Sandwich plate system consists of face that from plate and core form composite. Clam shells are one of the waste materials that can be used as filler on the core. The composite material that use as a core is a mixture of clam shells powder as filler and resin as a matrix. The combination of clam shells powder and resin, produces strong composite materials. Sandwich plate system using core from clam shelsl powder and resin produce good strength. The material using 20% clam shells powder as filler of the resin weight has maximum stress 53.32 N/mm2 on the deck and 53.20 N/mm2 for 30% of filler by weight of the resin. The maximum stress value is still below the permission stress required by the class rule.

Abstract

Graving dock gate merupakan salah satu bagian konstruksi daripada graving dock yang berupa konstruksi baja. Konstruksi graving dock gate yang berhadapan langsung dengan laut harus mampu menahan beban dari air laut setiap saat. Dengan melakukan variasi pada konstruksi pintu didapatkan hasil desain yang cukup optimal dari sisi kekuatan maupun sisi building cost. Pada penelitian ini dilakukan perhitungan kekuatan graving dock gate dengan menggunakan metode elemen hingga. Variasai dilakukan dengan empat jarak pembujur yaitu jarak pembujur 0.55 m, 0.60 m, 0.65 m dan 0.70 m. Dengan bantuan software metode elemen hingga didapatkan hasil nilai tegangan maksimum von Mises masih dibawah ReH 235 N/mm2 dan pintu dengan jarak pembujur 0.7 m memiliki tegangan maksimum von Mises terendah yaitu 108.58 N/mm2  serta pintu dengan jarak pembujur 0.55 m memiliki tegangan maksimum paling tinggi yaitu 155.84 N/mm2. Perhitungan building cost yang dilakukan, didapatkan pintu dengan jarak gading 0.65 m memiliki building cost yang paling rendah dan jarak gading 0.60 m memiliki building cost yang paling tinggi.
