Studi Eksperimental Pengaruh Tingkat Ketebalan Core Paper terhadap Beban Maksimal dan Defleksi Palet Berbahan Composite Core Papers (CCP)

Abstract

Pallets are objects that function as supports which are usually made from wood, which is limited in quantity, so innovation is needed by changing the raw material from wood to core paper which is environmentally friendly and can be recycled. One of the main problems is how to design pallets that have appropriate specifications, namely light weight but capable of lifting a fairly large maximum load. This research was carried out by observing the effect of core paper wall thickness on the maximum load of the pallet so that a pallet that is light in weight but strong enough to lift large loads will be obtained. This research was carried out by gradually loading several pallet specimens and then calculating the ratio between the weight of the pallet and its maximum load to determine the core paper with the appropriate wall thickness to lift a load of up to 3 tons while remaining light and safe. In this study, it was found that a pallet with a core paper wall thickness of 5 mm weighed 12.06 kg, a maximum load of 3,512 kg with a maximum average deflection of 9.4 mm and a safety factor of 1.173, a pallet with a core paper wall thickness of 7 mm weighed 17.52 kg, maximum load of 3,920 kg with a maximum average deflection of 9.1 mm and a safety factor of 1.308 and a pallet with a core paper wall thickness of 10 mm has a weight of 23.45 kg, a maximum load of 4615 kg with a maximum deflection that occurs is 8.65 mm and a safety factor of 1.538. So it was concluded that a pallet with a core paper wall thickness of 5 mm was the most optimal because is the lightest pallet but still able to accept the targeted load. With this research, core paper can be obtained with a wall thickness that is adjusted to the maximum load that you want to achieve before producing core paper pallets.
