Published: October 2022

Research on the corrosion rate of ASME SA-283 alloy steel has been carried out in the coastal environment. Corrosion is a decrease in the quality of the material that occurs due to the environment, where the coast is a splash zone area which is rich in salt content as a trigger for corrosion. Alloy steel is a material that is used widely as part of the construction of dock buildings on the coast The study was carried out by giving coating defects to ASME SA-283 material and varying the salinity in the splash zone area, where the coating thickness ranged from 350 μm - 410 μm and salt splash testing was carried out for 15 days. The results of the salt splash test show the types of corrosion that occur, namely pitting corrosion and unifrom corrosion. The largest corrosion rate occurred in the area that experienced a coating defect of 1,705 mm / year. The effect of coating on the corrosion rate is very large and the effect of coating defects on corrosion growth is quite high because the coating that functions as a protective specimen has been lost. The aim of this study are expected to become a reference for coating protection data in preventing corrosion growth in coastal environments. Keywords— Coating Defects, Corrosion Rate, Splash zone, Salinity.

Abstract Coconut plantations reach more than 106 hectares of the 831 thousand hectares of plantation areas in Aceh. Meanwhile, the total production reached 63 thousand tons with a productivity level of 818 kilograms per hectare. Most of it is still traditionally produced to produce coconut milk from these coconuts. The design of the coconut milk production machine has been carried out and before it is used a vibration test must be carried out to determine the operational feasibility of the machine. This study aims to measure the vibration level of the centrifugal tube frame for the coconut milk production machine with a centrifugal system capacity of 10 L / hour. The test was carried out at three levels of motor rotation, namely 1000 rpm, 1500 rpm and 2000 rpm with repeated measurements carried out five times at each motor rotation speed, the measurement results were compared with ISO 2631-1 standards and Kepmenaker number KEP-51 / MEN / I999. The results showed that testing the vibration of a coconut milk production machine with a centrifugal system with a capacity of 10 L / hour stated that it was safe if it was operated for less than 4 hours for a motor rotating speed of 1000 rpm, for a motor rotating speed of 1500 rpm it was safe to use if it was operated for less than 3 hours, while for rotation 2000 rpm motor is good and comfortable to use for less than 2 hours.

AbstractMaintenance is all activities needed to maintain or maintain the quality of equipment or machines to keep them functioning properly, for that maintenance is very important at PT. XYZ.Smooth production is highly dependent on the reliability and readiness of the machine, therefore a maintenance policy is needed by determining the priority of the machine to be maintained so that the reliability of the machine is maintained. The machine under study is the Stationery Spot Welding machine for both assy parts and body parts. The distribution model used is the exponential distribution model, from the form of the data it can be determined treatment. The data needed are machine working hours data, corrective maintenance time data, SDT (supply delay time) and ADT (administrative delay time) data, as well as preventive maintenance data. From the exponential distribution pattern, the cumulative function values, lamda, machine reliability, MTBF (mean time between failure), MTBM (mean time between maintenance), machine readiness time (availability) for each machine will be obtained. From the results of data processing, the reliability of the Stationery Spot Welding machine type SSW-35-Ndz, type SSW-50-Ndz, and type SSW-70-Ndz is 36.7%. This shows a very low level of reliability, therefore preventive maintenance is needed. In addition to reliability, MTBM is also obtained as a preventive maintenance schedule on the SSW-35-Ndz engine once every 1023 hours, the SSW-50-Ndz engine every 628 hours and the SSW-70-Ndz engine every 628 hours.

Published: October 2022

This study aims to determine the effect of bond ratings, return on assets (ROA), debt to equity ratio (DER), and firm size on yield to maturity (YTM) on several corporate bonds on the Indonesia Stock Exchange during the 2013-2018.The research method used is a quantitative research approach. The research method used was purposive sampling which resulted in 71 bonds from 29 firms as the samples.
The results showed that bond ratings and DER had a negative effect on bond yields, while ROA and company size had no effect. This finding supports the findings of several previous studies which simultaneously strengthen the position of bond ratings and DER as determinants of yield. The results of the classical assumption test show that the model formed is free from classical problems so that it can be a good predictor of bond yields.

Experimental results on the high-pressure phase diagram of boron nitride

Published: October 2022

Abstract
We present the boron nitride (BN) phase diagram at 3–6 GPa and 1100 °C–2200 °C using a modified belt-type high-pressure apparatus. The cubic BN (cBN)–hexagonal BN (hBN) phase boundary was determined using the hBN–Mg3BN3 catalyst system as a starting material at 4–5.5 GPa. Additional experiments were conducted at 3–4 and 4–6 GPa using cBN powder or hBN–Ca3B2N4 catalyst as a starting material. In the hBN–catalyst system, the rate of cBN nucleation was reduced by the growth of metastable hBN crystals under the cBN-stable pressure–temperature conditions. The stable BN phases were identified from the samples reacted with a longer run duration. The phase boundary line between hBN and cBN was determined as the equation P (GPa) = T (°C)/400 + 0.3, which agreed with the boundary lines calculated by Gruber and Grüneis and by Nikaido et al.
