Abstract

Total productive Maintenance (TPM) is an initiative to optimize the effectiveness  of manufacturing equipment which the objectives are elimination of all accidents, defects and downtimes [5].  The fundamental measurement of   TPM    using  a method   called the Overall Equipment Effectiveness (OEE). The study  was began by  root cause   identification of losses using  Root Cause Failure anaysis (RCFA), OEE was calculated based on the metrics  calculation which consist of availability metrics, performance metrics, and quality metrics, while reliability was calculated based on the value of MTBF.It is followed by recommendation of TPM  for  improvement of  losses .  The results  of this study  indicate that the value of OEE is not  achieve of world-class standards, where OEE is only  35,38%. The  factor witch greatly affects of   poor  OEE and reliability is  downtime loss  in the machine, which   is 2394,8 sec / process / day or 88,07% of all total losses. The proposed  improvements of losses  are application  of Autonomous Maintenance and  5S concept, making of  the preciseprocess operating standard   based on  the machine conditions,  need for planned maintenance, focused improvement,  quality maintenance and most important, supervision of the machine operator.

Abstract

Manual Materials Handling (MMH) activities still widely used in a job. This is because in this activity has a high flexibility, inexpensive, and easy to apply. However, these activities also constitute a risk when applied to the inadequate  environment, less support of tool, and bad posture of work. Therefore, measurement of safety limit in doing the job by using a calculation based on the equation of NIOSH Lifting Index. The case study at PT. Central protein Prima Surabaya is the removal of shrimp feed bag that still use manual way. Acquisition of STRWL calculation results obtained for the removal of shrimp feed bag stacks 1, 2, 3, 4, 5, 6, and 7 from 5,003 Kg to 67,41 Kg. Actual load which worker must lifted in this case study on a pile of 1 to 7 is 25 kg. Load  is lifted for the removal of shrimp feed bag bigger than STRWLmake it not feasible. CLI obtained in shrimp feed bag removal activity is 6.041 which value exceeds 3. Therefore CLI in this case study may create a risk of spinal cord injuries and to do their job changes. By measuring the changes in safety limits and do the work, expected reduced risk of injury to workers. After measuring the safe limit for the removal of bag obtained load is lifted workers have the risk of spinal injury, so it is given recommendations for improvement is by doing a redesign on a conveyor in the form of additional elevation (vertical) 57 cm at the end of the conveyor, as well as shortening the horizontal distance between the worker's body with a bag of shrimp feed time of transfer. With these recommendations obtained a decrease CLI becomes 1.795, which means that the risk of injury is between 1 <CLI ≤ 3 and can be reduced.

Abstract

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. Keywords:

Abstract

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.
