Abstract
Nowadays business communities are vulnerable to risk, because risk is not only inherent in every activity or business process of the company but also arise in various forms and types. Risks that occur in each company might be different and can present in various forms and cause negative impacts. Thus it is essential for companies to have a proper SC risk management in order to survive in a risky business environment. In this study, integration of the supply chain risk management model will be carried out by using House of Risk (HOR) and Analytic Network Process (ANP) model. House of risk is an innovative model for proactive SC risk management which combines the basic ideas of two well-known tools: the house of quality of the quality function deployment and the failure mode and effect analysis. HOR phase 1 is used to determine which risk agent will be prioritized in advance for precautionary measures and ANP to obtain the best alternative action. There are several steps of the integration method. First of all is mapping business processes. Second, identifying risk events and risk causes. Third, conducting risk assessments and determining the aggregate risk potential, which risk agents are need to be prioritized based on the Aggregate Risk Potential (ARP) value from HOR 1. Fourth, identifying which actions are appropriate to minimize risk agents by Analytic Network Process (ANP) modeling and each of these actions will be given weight to obtain the best alternative action. ANP is a tool to determine correlation between risk mitigation and hence rank those mitigation based on the priorities. The second phase of HOR is used to determine correlation between risk mitigation and the event risk and also its effectiveness based on its degree of difficulty to be applied. The output of this phase is a list of priorities on the mitigation risk which is relatively possible and feasible to be applied and hopefully capable to mitigate the risks. This study is conducted on 3 reputable manufacturing industries to be compared and analysed. HOR2 is intended to prioritize the proactive actions that the company should pursue to maximize the cost-effectiveness of the effort in dealing with the selected risk agents in HOR1. This research shows that risks apply differently on each company. Hence, the ANP ranking is different. Mitigation risk’s rank is determined from the second phase of HOR as it has considered correlation aspect of risk agents and its degree of difficulty to be mitigate. Finally, special actions are applied to various risks such as performance appraisal to the staffs. Further study is needed with ISM method in order to make mitigation actions are focused on the companies.

Abstract
Employee performance is fundamental to successful execution of construction project where it depends by internal and external factors. To increase employee performance, the organization should analyze the external factors that may reflect on employee performances. This research examines the relationship of work-life balance, mental workload and job satisfaction with the performance of construction employee. Data collection using questionnaires that have been tested for validity and relibiality and sampling technique using purposive sampling. The data processing was done by using NASA-TLX method to find out the mental workload and SEM (Structural Equation Modeling) method. The results showed that the mental work load negatively affect job satisfaction and employee performance, work-life balance positivetly affect job satisfaction and employee performance, and job satisfaction positively affect employee performance. The findings of the paper can be a guidance for construction companies to formulate strategy for increasing employee performances by adding the number of employees for the workload to be decreased, compressing work week for a balanced work-life and to promote the employees more frequently to increase job satisfaction.

Abstract
The purpose of this study is to make productivity better by means of work study, continuous improvement, Muda elimination, and ECRS in electronics part industry which was conducted from November 2018 to March 2019, from a case study of technical training department of AAA Co., Ltd. The data were collected from managers and supervisors and the problems were analyzed by brainstorming together with cause and effect diagram. Referring to the results, it was found that crucial problems of technical training department occurred from a delayed process in printing, grading, scanning examination results and storing paper exam, waste of paper exam usage, messy area due to paper exam storage, and erroneous grading score. Considering the examination process, whole process of examination could be changed from using paper exam to using online exam via website of a company or QR code. Regarding the grading process, the grading process could be changed from manual to online system, which is accurate and prompt to present the score immediately. The online examination can reduce usage of paper and printing ink, scanning and waiting time, and storage area. In addition, employees can test by themselves anytime which helps them not to worry about their work and may result in higher score. The standard time of examination process was reduced from 5,769,535 seconds to 4,683,005 seconds per 3,035 persons, with productivity growth accounting for 23.20 percent of improvement. The examination cost was decreased from 124,957.53 THB to 97,562.60 THB per 3,035 persons, with productivity growth accounting for 28.08 percent of improvement. After applying online examination, the findings showed that employee satisfaction level was increased from 3.21 to 4.10, accounting for 27.73 percent of improvement.

Abstract
The automotive industry is undergoing a very rapid development, where the motorcycle industry is one of them. Although motorbikes are a widely used means of transportation, it doesn’t mean that motorbikes don’t have obstacles. This research is motivated by observations and experiences of the researchers, that a motorcyclist wants comfort while driving, but on a motorcycle there can be many factors that cause problems. For example experiencing a lack of air pressure on tires (deflated) or a flat tire becomes a serious problem when driving on a quiet road so that the driver feels disturbed. It is necessary to make a tool that can be used to pump tires easily and efficiently. In making and designing tools, product specification design methods were used, ranging from task translation to detailed design. The Product Design Specification (PDS) method focuses on the criteria for being achieved in ideas and concepts. The value of pressure from the theoretical calculation is different from the calculation of the tool, the results of the theoretical calculation of the tool obtained air pressure of 38.8 Psi, while the tool testing can directly reach a pressure of 30 Psi. Although figure 30 Psi has been able to fill the front and rear tires of a motorcycle, but the difference in numbers is certainly caused by observable factors. With a variety of factors that affect the performance of the tool but still can meet enough criteria to be able to pump motorcycle tires and also the design of this tool is made for use in emergency conditions, so that when a motorcycle experiences a flat tire and the condition is not in the immediate vicinity with a tire pump workshop, the tool can be used.
