Analysis of Palm Fiber and Coconut Coir Usage as Purse Seine Cargo Chamber Insulator

Abstract

Indonesia's annual marine fish potential of 6.5 million tons is spread over the waters of Indonesia's Exclusive Economic Zone. The constraint of which are often faced by fishermen is the decay that occurs during the storage process in which the fish becomes less fresh when it comes to the fish auction. The decomposition rate of fish after fishing is strongly influenced by fishing techniques, handling techniques, and onboard storage. The cooling or freezing process is the best method chosen for handling the catched fish to maintain its quality and freshness. This study was conducted by modifying the insulation material of purse seine cargo hold using a coolbox made of insulated materials from coconut coir and Palm Fiber. The purpose of this study is to know the influence of coconut coir and Palm Fiber composite insulation to temperature and cooling time in which will be compared with styrofoam insulated coolbox. The study was conducted by testing some specimens which will be selected with the thermal conductivity and lowest density. The compositions which is chosen were coconut coir and Palm Fiber composite that is mixed with polyurethane glue 4:4:1 ratio, having a thermal conductivity of 0.4643 W/mK and a density of 0.18 g/cm 3. Coolbox's test using coconut coir and Palm Fiber composite insulation was done using a 400 gram fish as a cooling load and ice that had been destroyed weighing 2 kilograms as a cooling source. Coolbox with coconut coir and Palm Fiber composite insulation has the lowest fish temperature of 0.7 o C, while the coolbox with styrofoam insulation has the lowest fish temperature of 1.8 o C. In addition, coconut coir and Palm Fiber composite coolbox is able to keep temperature below 20 o C for 16,5 hours, while with the same treatment styrofoam insulated coolbox is only able to keep the temperature below 20 o C for 16 hours. So it can be concluded the use of coconut coir and Palm Fiber composite is effective as insulation material because it can offset the performance of the insulation styrofoam .

Analysis of the Mechanical Properties of Teak Sawdust-Reinforced Composite Boards Affected by the Alkalization Process

“…In Aceh a lot there is an industry processing wood, especially wood teak. Production results include the development of windows, chairs, panels, and accessories that use wood as an ingredient main, while with development of fast industry results in the accumulation of waste in the form of powder saws and particles [5][6][7][8]. Waste powder saws from wood teak often left pile up even if only part only used _ for ingredient burn.…”

“…A study about the utilization mixture of powder saw wood teak and fiber dregs sugarcane has also been conducted by Baheramsyah et al [5]. The study was conducted by modifying the isolation ingredient coolbox to increase the nature of the mechanic.…”

“…The modulus of rupture (MOR) is a continuation of the modulus of elasticity testing, where this test continues loading until fracture toughness is obtained. The determination of the MOE value can be calculated by the formula:(5) Where is MOR = Modulus of fracture (kgf/cm 2 ), P = Maximum weight (kgf), L = Span length (cm), b = Width of test sample (cm), and h = Thickness of the test sample (cm).…”

Utilization of Mixture of Teak Wood Sawdust and Bagasse Fiber using Treatment of Fiber Variations and Alkali NaOH Immersion as A Refrigerator Insulation Material

“…This causes the O group to become free radicals and reactive to C then form an epoxy ring (C-O-C) resulting in a series of groups releasing bonds to group O and producing two separate benzene rings. Both benzene rings each have an O group that is reactive and reacts with Na + and then dissolves in a base solution so that the lignin disappears when rinsed and the fiber diameter decreases [15][16][17][18].…”
