Abstract

Composites are materials that are formed when two or more different components are combined (Kroschwitz, 1987). K. Van Rijswijk et al in their book (Natural Fiber Composites, 2001) describes a composite is a hybrid material made of fiber-reinforced polymer resin, combining mechanical and physical properties. Research on the strength analysis of particle board by utilizing bagasse so that it has a better economic value. Variations in the ratio of fiber fraction and polyester resin were 2:40, 5:40 and 8:40 with each and mixed based on the ratio of fiber weight fraction and resin weight. Based on the analysis using ANOVA, it was found that the best composition of the final composite product was in the composition of 8 grams of bagasse fiber and 40 ml of polyester resin. The composition has a bending strength of 9, 19 N / mm2. Based on the analysis using ANOVA, it was found that the optimization parameters were 0.04 millimeter layer thickness and 16 seconds lighting time, the optimal results were in the dimensions of 40.01 millimeters in diameter and 3.20 millimeters of thickness.

Abstract

Komposit adalah suatu material yang terbentuk dari kombinasi dua atau lebih material pembentuknya melalui campuran yang tidak homogen, dimana sifat mekanik dari masing-masing material pembentuknya berbeda. Dari campuran tersebut akan dihasilkan material komposit yang mempunyai sifat mekanik dan karakteristik yang berbeda dari material pembentuknya. ( Endi, 2018).Penelitian tentang pengaruh penyusunan serat kulit jagung pada komposit resin polyester terhadap pengujian bending sebagai pengganti plafon dengan maksud memanfaatkan limbah kulit jagung sehingga memiliki nilai ekonomis. Variasi perbandingan struktur penyusunan filler/serat yaitu, Serat lurus, serat menyilang,dan serat anyaman.Berdasarkan hasil perhitungan ANOVA didapatkan hasil bahwa serat yang memiliki kekuatan terbaik adalah serat dengan penyusunan anyaman dengan nilai kekuatan bending sebesar 1,96 N/mm2, hal ini di karenakan penyusunan yang baik antar susunanya sehingga jadi lebih kuat.

Abstract

Fire is a disaster that no one wants. Fires can occur anytime and anywhere, one of which is offices, buildings, warehouses, and even forests. Fires in buildings can cause losses in both material and non-material properties. To extinguish the fire, you need supporting equipment, for example a Fire Extinguisher Kit (FEK), which is a fire hose reel. To produce this tool, a production aid is needed in terms of gripping the workpiece that will be used as a fire fighting kit product. Fire Hose Reel production aids are production workpiece holder tools that are used in order to make accurate doubling of components to get good work results in production, of course there should be compatibility in terms of the position of the workpiece with the machine used. The fixing device is used which is designed to position, hold, and support each part so every welding performed is within the specified limits. In the process of designing and manufacturing, this Welding Tool for Production of FEK uses software to calculate the load that these production aids can withstand and for the manufacturing process tools such as cutting grinders, drilling machines and other bench work tools are used. This tool can withstand the weight of objects up to 50 kg. with a deflection of 0.055 mm.
