Abstract

Serat batang pisang merupakan jenis serat yang berkualitas baik, dan merupakan salah satu bahan alternatif yang dapat digunakan sebagai penguat pada pembuatan komposit. Penggunaan serat pelepah pisang sebagai bahan komposit merupakan salah satu alternatif dalam pembuatan komposit secara ilmiah. Tujuan penelitian ini untuk mengetahui pengaruh variasi fraksi volume serat pelepah pisang terhadap kuat tarik dan daya serap air dengan resin polyester sebagai matrik. Komposit ini dibuat dengan perendaman NaOH sebesar 5% pada serat selama 2 jam, menggunakan teknik hand lay up dan press molding dengan variasi fraksi volume serat pelepah pisang 23%, 28%, 33%, 38%, sedangkan resin polyesternya 77%, 72%, 67%, 62%,  dengan orientasi arah serat searah. Spesimen komposit dipotong sesuai standar ASTM D 638-01 untuk uji tarik dan ASTM D 570 untuk uji daya serap air. Hasil penelitian uji tarik didapat bahwa kuat tarik, regangan, modulus elastisitas dengan nilai tertinggi pada kuat tarik  226,82 Mpa dengan fraksi volume serat 28%, pada nilai regangan 0,035 mm/mm dengan fraksi volume serat 28%, nilai modulus elastisitas 12930,94 Mpa dengan fraksi volume serat 38%. Model patahan komposit berpenguat serat pelepah pisang bermatrik resin polyester ratarata dapat diklasifikasikan sebagai jenis patahan banyak. Dan hasil penelitian uji daya serap air mendapatkan nilai terendah pada uji daya serap air yaitu pada fraksi volume serat pelepah pisang 23% sebesar 0,0079%. Sehingga serat pelepah pisang dapat digunakan untuk komponen industri khususnya pengusaha mebel karena mempunyai kuat tarik yang tinggi dan daya serap air yang kecil.

Abstract

Abstract— Processing of natural fibers as a support material for composite materials has been widely carried out. Some studies use chemicals as a medium for processing fiber while the treatment with natural ingredients has not been done much. This study discusses the ability of the matrix to penetrate the coconut fiber. Coconut fiber that has been cleaned soaked in a solution of limestone water. Immersion is done with a variation of the lime mass percentage of 0; 2.5; 5; 7.5; 10% with 8 hours soaking time. The matrix used is unsaturated polyester yucalac 157 BQTN-EX. Wettability testing by dripping a matrix on coconut fiber. Coconut coir fibers that have been dripped with a matrix in the photo to determine the contact angle. The results of measurements and observations that with variations in mass percentage of 5% limestone with an immersion time of 8 hours have a contact angle of 11O˂Φ˂31O. Immersion with a percentage of 2.5% shows the surface of the fiber has not changed. Immersion of 7.5% and 10% of the surface of the fiber has been damaged, so the matrix can not absorb the coconut fiber to the maximum. Keywords—: coconut fiber; limestone water; contact angle; wettability; SEM.

The mixture is put into a molding machine and then printed with a pressure of 80 kg/cm2, 115 kg/cm2, 150 kg/cm2, and 185 kg/cm2. Charcoal biobriquettes are dried in an oven at 105 ̊C for 1 hour. In this research, the mass density and moisture content of the mahogany wood waste met the Indonesian biobriquette standards, the results of this study obtained the higher density of 0,55 g/cm3at a pressure of 150 kg/cm2. The results lowest water content of 47,2% at a pressure of 185 kg/cm2. The lowest combustion rate is 0,257 g/min at a pressure of 185 kg/cm2. Keywords—: mahoni wood waste; pressure; moisture content; combustion rate.

Abstract

The type of cultivation that will be developed is an enlargement business with catfish commodities. Catfish was chosen as a commodity to be developed because this type of fish is easier in terms of marketing, harvest time is faster and maintenance is easier, if in practice applying good fish farming methods accompanied by appropriate management and technology. The method used is the use of iron trellis as a medium to support the load and tarpaulin as a water retaining pad. The model imitated is the drum principle, making it easier to maintain cleanliness and save water. The water contained in the pool, when it is about to be cleaned, is not all thrown away. The water that is discharged is only the bottom of the pool or the bottom of the pool. Water at the bottom or bottom of the pool that contains dirt deposits. The results obtained are the ease of making ponds, maintenance, filling water, and saving water with an open and close faucet system at the bottom.

Abstract

In the rapid development of industry and construction in the current era, iron is a material that is widely used as a material in construction activities around the world. However, iron has the disadvantage of being very susceptible to corrosion. Corrosion is a decrease in metal quality due to electrochemical reactions with the environment. One of the corrosion prevention measures taken against iron is the addition of corrosion inhibitors to inhibit the corrosion rate. Inhibitors from natural materials are an alternative as an environmentally friendly inhibitor. This study aims to determine the efficiency of using melinjo leaf extract inhibitor in inhibiting corrosion rate in 3% Nacl corrosive media. The method used is the mass loss method to see the value of the corrosion rate. This study uses ST 37 steel plate material with a size of 2x1.5x0.12 cm. The concentration variation of melinjo leaf extract is 0%, 3%, 6%, and 9% with a soaking time of 14 days. The results showed that the addition of melinjo leaf extract as an inhibitor can reduce the corrosion rate with the smallest corrosion rate of 0.0449 mmpy and the greatest inhibitor efficiency is at a concentration of 9% at 51.72%.
