Customer loyalty is the key to customer retention, so that customer loyalty needs to be accomplished before reaching customer retention. Customer satisfaction is considered as an important factor and a positive effect on customer loyalty so far. Several previous studies have revealed that, besides customer satisfaction, there are other factors that determine customer loyalty. Until now, research on other factors that determine the customer loyalty give varies results. This research will develop a model of customer loyalty in the Islamic banking institutions, especially the Bank Syariah Mandiri (BSM) where data trends of satisfaction and customers loyalty is not proportional, by using the PLS-SEM in data processing. The aim of this study was to develop a model of customer loyalty in banking institutions, especially the Islamic banking (Bank Syariah Mandiri). The results showed that customer satisfaction is not significantly affect customer loyalty, and only the quality of services that significantly affect customer loyalty. Switching barrier and customer trust is also proven not affect customer retention both on the main effects and on the interaction effects with customer satisfaction. The result is expected to be a managerial reference to increase customer loyalty.

Time is one of the factors to assess a worker's performance in utilizing the available resources. Operator in his work requires efficient time to improve work productivity. One of factory in produce a shrimp feed in Surabaya has a large production level. In the production process, the packaging department in this company still uses human resources in their production process and the company define the standard of production without using standard time. This paper investigates the opportunity a logical analysis in determining the standard time in this company. The determination of the standard time in the packaging process requires comprehensive analysis. Objects observed are four operators in the packaging department that carried out the activities of filling bag the shrimp feed with 40 replication for each data. The work measurement was conducted by direct method using Stopwatch Time Study (STS) with snap-back method. The results of this study indicate the standard time value of the four lines packaging is not much different or almost the same. Sequentially the standard time workers line 1 to line 4 is 7.325 seconds, 7.240 seconds, 7.225 seconds, and 7.065 seconds. Allowance used for workers is 8%. However, the existing production rate of company is higher than the production rate of work measurement calculation. This is due to the difference of definition in employee allowance rate and performance rating.

The human stress level is rather intangible, and therefore cannot be directly measured. However, this stress can be correlated to external and/or internal factors, which are rather tangible things, such as heart rate, Systolic-Diastolic Blood Pressure, salivary α-amylase, and skin temperature. These factors measurements are provided in wide ranges and vary individually lends itself naturally to fuzzy sets and fuzzy logic. This research is aimed at assessing respondents stress level through the changes of physiological factors above over time. The subjects of this study are 10 healthy adults, aged between 23-35 years old. The measurement time divided into four periods, namely pre-stressor, stressor-I, stressor-II and post stressor period. Pauli-test and mental arithmetic test was used as stressors. Obtained data were analyzed using Fuzzy Inference System (FIS) toolbox in MATLAB. By using fuzzy inference system model, the system succeeds to predict subject stress value/index based on subject physiological value. The result showed that the changes in human factors affects human stress value/index, although the subjects stated that their stress level on the same level their physiological factors were changed during measurement, and the models showed the changes of subject stress value during different period of measurement time.
