This raises fears of all sectors especially in business. All regulations and policies such as social distancing, health protocols, work from home, travel restrictions, and self-isolation at home have been implemented by the government. As a result, all workforce must be reduced in all economic sectors, which causes an increase in the number of unemployed. If schools and offices are closed, some of the populations are influenced to change their life into a healthy lifestyle in order to prevent any disease that will come to them. This case will impact to their trust towards the food-seller and they will decide whether they purchase or not. Hence, this research explains about the influence of the lifestyle towards purchase decision through customer trust as the mediating variable. The variables of this research such as the dimensions of lifestyle (activity, interest, and opinion) as independent variables, purchase decision as dependent variable,and customer trust as the mediating variable. This research is a quantitative research which using SmartPLS 3.0 (Partial Least Square Structural Equation Model). The online questionnaire spread to 171 respondents by snowball sampling. The result show that the positive influence of lifestyle (activity, interest, and opinion) on purchase decision. In additional, the lifestyle positive influence on purchase decision trough trust as the intervening variable. 2020-01-01T00:00:00Z http://repository.president.ac.id/xmlui/handle/123456789/13893 THE CHANGE OF INDONESIANS LIFESTYLE TOWARDS FOOD PURCHASE DECISION DURING COVID-19 PANDEMIC Azmi, Amira Nurul; Genoveva The corona virus has attacked human life by taking away their freedom. Since the spread of the corona virus throughout the world at the end of 2019, every country has issued social distancing policies, including in Indonesia. The impact of this viral pandemic has damaged various existing businesses, including food franchises with international brands. The purpose of thisstudy isto analyze purchasing decisions at fast food franchises with international brands, assuming international brands already have cleanliness standards, high quality and a more comfortable environment (location), so that consumer confidence is more than other local brands. The trust factor is also used in this study as an intervening variable. This research is a quantitative study using an online questionnaire as a data collection tool. The valid questionnaires are filled in by 180 respondents. The sample used was non-purposived sampling with simple random sampling. Hypothesis testing uses the Structural Equation Model (SEM). The results showed that Food Safety, Food Quality and Environment had a significant effect on Purchasing Decisions during the COVID-19 pandemic. Meanwhile, Quality and Environment have a significant effect on trust, which is an intervening variable in this study. This study concludes that Food Safety, Food Quality, and Environment have a positive and significant effect on consumer confidence so that it affects purchasing decisions. 2020-01-01T00:00:00Z http://repository.president.ac.id/xmlui/handle/123456789/11749 Hot forgeability of SCr420 low-alloy steel for piston rod application Anggraini, Lidya; H Kartomi Microstructure development and mechanical property of SCr420 low-alloy steel (equivalent to AISI 5120) obtained by the forging process have been investigated. The relationship between the forgeability and mean grain sizes were examined. The type of forging was carried out by die-forging at a temperature of around 1150 - 1190°C using a machine tonnage of 1600 tons capacity with 2 times forging variation. The high aspect ratio can be maintained through the steel forming applied for piston rod by the hot forging process. Vicker's hardness mechanical tests in initial and forged conditions were carried out at room temperature. The results demonstrate that the Vickers hardness of initial condition of 254.5 HV is much higher in comparison with the hot-forged material of 152.6 HV. The forged low-alloy steel processes the desired ferrite-pro eutectoid and pearlite microstructures, when followed by normalizing process, and deformation are achieved.

The piston fabrication process is carried out by super forging using Aluminum as a raw material with a compound choice by Silicon or Magnesium. In addition, the outer layer of the piston is covered by molybdenum with the coating process as nanotechnology to prevent corrosion. Furthermore, the finishing is controlled by the programming system machine named CNC (Computerized Numerical Control). In addition to CNC, the automation system is carried out by the KIRIU machine which is also used in this study. The results of this study show that the use of Al-Si alloy base material has better piston quality and able to withstand high compression or high engine speed. Then, the Al-Si superforging piston compared to the two final automation processes of CNC and KIRIU. The evaluation results have proved that the KIRIU machine provides high accuracy and the actual production increases by 20% compared to CNC.
