Abstract

The limited availability of lowland swamp areas that can be utilized makes floating rafts a commonly used solution. However, conventional floating rafts do not have a long lifespan and require additional floatation devices. This condition leads to a lack of flexibility and increases the construction costs of floating rafts. This study aims to design a floating raft made of pvc pipes by utilizing plastic gallons. The research method used is design and construction, which consists of three stages: the design approach stage, the structural design stage, and the functional design stage. Volume, buoyant force, and design load will be calculated to determine the appropriate type of floating raft and to measure its load-bearing capacity. The research results showed that the floating raft made from PVC pipes, utilizing plastic jugs, which was designed in this study, proved to be effective for use in lebak swamp areas. Floating raft type 3 had the largest volume, which was 0.058173 m³, while the smallest was floating raft type 1 with 0.0339 m³. The greatest buoyant force was produced by floating raft type 3, at 570.1 N, and the smallest by type 1, at 332.22 N. The highest planned load was supported by floating raft type 3, with a weight of 58.173 kg, while the lowest was supported by type 1, at 33.9 kg. The standard distance that was determined ranged from 1 to 5 cm. Floating rafts with a distance between the water surface and the plastic jug of -1.8 cm and -2.5 cm were found to be suitable for rice cultivation. Meanwhile, the raft with a water-to-jug distance of -1.8 cm was deemed suitable for pakcoy cultivation.
