Microstructure and Wear Resistance of Fe-Al-Mn-Mo Alloy after Deep Cryogenic Treatment Ratna Kartikasari*, Angelio Fila Defianto Maitano Mechanical Engineering Department, Institut Teknologi Nasional Yogyakarta, Jl. Babarsari no. 1, Catur Tunggal, Depok Sleman, Yogyakarta, Indonesia 55281 *ratna[at]itny.ac.id Abstract The Fe-Al-Mn alloy is one of the alloy steels that is candidate for cryogenic applications to replace the Fe-Cr-Ni alloy. The addition of Mo to the Fe-Cr-Ni alloy causes an increase in mechanical properties and corrosion resistance without changing the cryogenic properties. This research aims to study the effect of Deep Cryogenic Treatment (DCT) processing time on the microstructure, hardness, and wear of Fe-Al-Mn alloys with the addition of 0.5% Mo. The DCT process was carried out by immersion in liquid nitrogen at a temperature of -196&#730-C for 1, 2, 3, 4, and 5 hours. Then it was returned to room temperature. The tests carried out were microstructure testing using an optical microscope, SEM and EDS, hardness testing using the Vickers hardness method and wear testing using the Ogoshi method. The results of the microstructure test show that the Fe-Al-Mn-Mo alloy has a ferrite and austenite structure. The DCT process causes the ferrite structure to increase in size, while the austenite structure becomes smaller and more spread out between the ferrite grains. Hardness testing showed that the DCT process increased the hardness but not significantly. The wear test shows a decrease in the wear rate. The DCT process did not cause significant changes in microstructure and wear resistance, so Fe-Al-Mn-Mo alloys are suitable for cryogenic applications.

Abstract The covid-19 is affecting the global economy including the stock market. With Covid-19 spreading in a fast manner, the government has been trying to find a way to control the virus outbreak. As to achieve herd immunity, and with the asymptomatic transmission of Covid-19, it is believed that vaccination is the answer. Several studies have been carried out to explore the vaccination impact to the stock market and panel regression is one of the common analyses that have been carried out. However, there is a problem with using the panel model in ASEAN daily vaccination data and stock market which is the possibility of the existence of cross-dependency and/or heterogeneity. Therefore, this studies tried to explore and compare the spatial method to overcome spatial dependency using Spatial Autoregressive (SAR) and Spatial Durbin Error Model (SDEM) in the vaccination data. The spatial closeness are proxied by the bilateral cross-country investments. The results show that SAR and SDEM are not better fitting models compared to the panel regression model. we concluded that there is no spatial dependency existed in the vaccination to the stock market.

KNN Method for Handling Right-censored Data Abdul Kudus (a*), Suliadi (a), Yayat Karyana (a), Caecilia A Rahman (a) a) Dept. of Statistics, Universitas Islam Bandung, Jl. Ranggagading No. 8 Bandung 40116, Indonesia *abdul.kudus[at]unisba.ac.id Abstract The K-Nearest Neighborhood (KNN) method can be used to impute censored data. KNN imputations are designed to find the nearest neighbor^s K from incomplete data to the entire occurrence of a data, then fill in the missing data with the events that are most similar to their neighbors, if the target variable (or attribute) is categorical then the imputation refers to the majority of neighbors but if the variable is numeric then the imputation uses the average of the nearest neighbors. This article discussed the use of KNN imputations in the survival time of right-censored patients based on the averages of as many K as nearest neighbors. The distance from censored data to its neighbor was calculated based on two independent variables. The smaller the distance, the data becomes the closest neighbor because it has similar characteristics. The imputation value for the censored data was just the average of its neighbors which is forty six neighbors around the censored data.

Abstract Dynamics of water passing through a 90 degrees horizontal bend of 90 degrees is examined in the context of core catcher as a part of nuclear reactor. In this study, the dynamics is simulated using Moving Particle Semi-Implicit method. The simulation results are then compared to the experiments. The simulation results show that the water depth patterns obtained in this study are similar to experiment results. In addition, the travel time of water agrees with the experimental results. This shows the capability of Moving Particle Semi-Implicit method as an alternative numerical method for liquid transport.
