Abstract

Steel ropes are one of the most important parts of a lifting aircraft system. The strength of the steel rope varies, depending on the use and needs. A typical steel rope construction for elevators consists of 8 spins wrapped together, heading left or right with a core in the middle. Each steel rope spin consists of 19 wires which is 9.9.1, meaning 9 wires outside, 9 inside and 1 in the center. The cross-sectional area of steel rope (F152) based on the tensile stress for one steel rope (S) is 1.9 cm. The tensile stress that occurs on the steel rope is (S) = 1773 kg. While the permissible tensile stress is (Smax) = 2800 kg. The actual steel rope breaking strength (P) based on the safety factor with mechanism type and operating conditions (K) is (P) = 9753 kg. Steel rope used type: 8 x 19 = 152 + 1 Fiber Core with specifications: steel rope diameter (d) : 10 mm, rope weight (W) : 1.15 kg / m, steel rope breaking load (Pb) : 15,400 kg, rope breaking stress (σb) : 140-159 kg / mm². Because the tensile stress (S) = 1773 kg is smaller than the permissible tensile stress (Smax) = 2800 kg, it can be concluded that the steel rope is safe against the tensile load that occurs.

Abstract

Xylanase is an extracellular enzyme that is capable of hydrolyzing xylan (hemicellulose) into xylose and xylo-oligosaccharides. Xylanase can be produced by microbes through a fermentation process, the microbes used are thermophilic bacteria. Thermophilic bacteria are microorganisms that are capable of producing thermostable enzymes through fermentation. The bacteria used are MSS11, MS 16 and MS 18. These thermophilic bacteria can live at temperatures above 45°C-80°C. To determine specific enzyme activity, enzyme and protein activity values were tested using a 540 nm (enzyme) and 750 nm (protein) septovotometer. The method used in this research is descriptive in triplicate. The research was carried out at the Microbiology Laboratory, Faculty of Mathematics and Natural Sciences, Padang State University on December 23 2023. Beechwood medium which had been mixed with MSS 11, MS 16, and MS 18 bacteria was then incubated at temperatures of 55℃, 65℃ and 75℃ so that specific enzyme activity was obtained. Of these three temperatures, the optimum specific enzyme activity of xylanase is 65℃, where the specific enzyme value obtained at 65℃ is 3.31 U/mg. Meanwhile, at low temperatures, namely at 55℃, the enzymatic reaction is slow, namely it has an enzyme activity value of 1.02 U/mg. Finally, at a temperature of 75, there was a decrease in specific enzyme activity, where the specific enzyme activity value was 3.12 U/mg.

Abstract

The main semiconductor materials used are the elements Ge (germanium) and Si (silicon). The element Ge is found in nature in small quantities and silicon is the most abundant element in the earth's crust but its conductivity is low. The semiconductor material that has recently been frequently researched is Copper Tin Oxide (CuSnO3). CuSnO3 has high electrical conductivity and is quite abundant on the earth's surface. The synthesized CuSnO3 semiconductor is applied as a thin layer because of several advantages such as large output voltage, small electrode mass, and also a fairly long service life. This research aims to determine the optical and electrical properties of CuSnO3 thin films synthesized using the sol-gel method with dip coating techniques. CuCl2·2H2O, SnCl2·2H2O, methanol, and monoethanolamine (MEA) are the precursors used. The synthesized CuSnO3 thin layer was characterized using a UV-DRS instrument to determine the band gap value and tested using the four point probe method to determine its electrical conductivity. The band gap values with calcination temperatures of 500°C, 550°C, and 600°C are 2.55 eV, 2.83 eV, and 2.95 eV, respectively, with electrical conductivity of 348.46 102 S/cm, 155.48 102 S/cm, and 107.63 102 S/cm. From these data it can be concluded that the band gap value of the CuSnO3 thin layer will increase when the calcination temperature used is higher, and the conductivity decreases as the band gap value of the CuSnO3 thin film increases.

Abstract

Free fatty acids (ALB) are fatty acids that exist in a free state and are no longer related to glycerol. The method used in ALB analysis in CPO uses the alkalimetric titration method with the principle of determining acid levels using a standard alkaline solution that has known the exact concentration. The data collection process is carried out by calculating the % ALB in open and closed media CPO which is then calculated in excel to find out the comparison of the increase in % ALB so that the graph is obtained. a significant increase occurs in open media CPO because open media is more rapidly oxidized and more susceptible to contamination by air so that there is a faster increase in open media samples so that in open media the smell is more rancid than closed media due to the result of oxidation, namely hydroperoxide which gives a rancid smell and gives a brownish color to CPO.
