Abstract

The length and diameter of the fibers of palm frond is one of the factors that affect the physical and mechanical properties of the material WPC. This study aims to determine the effect of fiber diameter and length of the palm fronds to the properties and morphology of wood plastic composite (WPC). WPC samples prepared by the method of melt blending the fibers of palm fronds, PP, Maleated polypropylene (MAPP), and paraffin for 65 minutes at a temperature of 170 ° C and a rotor speed of 80 rpm using the Internal Mixer. The length and diameter of the fibers of palm fronds used is ± 1 mm, 1 cm and 5 cm in diameter filler: - 40 ~ + 60 mesh, - 60 ~ + 80 mesh and - 80 ~ + 100 mesh. While the ratio of the weight ratio of PP / fiber palm fronds are 50/50 and 70/30. The test results showed that the best mechanical properties resulting in a length of 1 mm and the diameter of the fiber - 80 ~ + 100 mesh at a ratio of polypropylene / palm frond fibers 70/30 with a value of 16.44 MPa tensile strength and flexural strength 31.21 MPa. In testing the physical properties of the best value generated with the water content value of 8,61%, the absorption value of 1.78%, the highest density value of 0.99 g /cm3 and thickness swelling lowest value of 0.33%, while in the SEM testing, interaction between filler and matrix are still lacking thus forming agglomeration as a result of the fiber and the matrix material evenly mixed at WPC.Keywords: fiber diameter, fiber length, physical, mechanical, morphological, wood plastic composite

Abstract

Diabetic ulcers are one of the complications often experienced by patients with diabetes mellitus. The incidence of diabetic ulcers has an impact on patients, families, health care, and society in general. Education plays an important role in the prevention of diabetic ulcers. This study aims to analyze the effect of health education based on the theory of planned behavior on the main factors of theory of planned behavior (attitudes, subjective norms, perceived behavioral control), intentions and diabetic ulcer prevention in patients with diabetes mellitus. The quasi-experimental approach pre-test and post-test with control group design was used in this study. There were 84 patients with diabetes mellitus divided into intervention groups and control groups. Questionnaires are used to assess attitudes, subjective norms, perceived behavioral control, intentions, and behavior prevention of diabetic ulcers. The statistical analysis showed significant differences in attitudes, subjective norms, perceived behavioral control, intentions, and diabetic ulcers prevention between the intervention group and the control group (p=0,000). This research suggests that education based on the theory of planned behavior can enhance the construction of the Theory of Planned Behavior (attitude, subjective norms, perceived behavioral control), intention, and diabetic ulcer prevention in patients with diabetes mellitus. Patient behavior change strategies can be done by applying health education based on the theory of planned behavior.
