As competition increases, delivering better service becomes more important; it is not with the expception of PT. Telekomunikasi Indonesia, Tbk (PT TELKOM), which is the only state-owned enterprise as well as the largest telecommunication and network service provider in Indonesia. This is because service quality is considered as an important aspect for the success of the service provider. This study aims to assess the service quality of PT. TELKOM for IndiHome products. A preliminary study showed that there are many customers complaining about IndiHome's service quality. In addition, the tight competition and the emergence of several similar service providers as well as attractive promotion will inevitably attract customers not to be loyal if PT. TELKOM does not immediately improve the quality of the service. This research was conducted not only to assess the service quality of IndiHome (using SERVQUAL), but also to give some recommendations to PT. TELKOM especially Regional 1 Sumatra in order to attain customer satisfaction. There were 153 respondents who participated in this study. The results show that on average, customers are not satisfied (the gap value is 1.539). This negative value means that the customers have high expectations of the services that should be delivered by PT. TELKOM, but in reality the performance of the service is not as high as their expectations. Therefore, some recommendations are given to improve the performance of IndiHome service quality so that the customers are satisfied.

Corrective action on the engine damage is a temporary emergency measure, so further action is required by conducting maintenance activities, prevention of damage (Preventive maintenance), and able to detect abnormal symptoms before the machine breakdown occurs. The sudden impact of machine damage resulted in disruption of planned production performance so that it is necessary to identify and analyze the factors that cause the machine damage. Establish maintenance method using Autonomous Maintenance, Preventive Maintenance and Reliability Centered Maintenance (RCM) concept to prevent machine failure from the beginning, through fault tree analysis (FTA) method, failure mode effect, and analysis (FMEA), mean time between failure (MTBF) is an analytical activity for implementing RCM systems on machines and critical components, able to identify and detect symptoms of malfunction before the machine is damaged. The results of the research get better application of maintenance system so that identification of important components can be anticipated from the symptoms of damage. Overall, there is an increase in performance seen from the increase of Overall Equipment Effectiveness (OEE) value, still expected to continue to increase according to JIPM 85% standard value. In conclusion FMEA, FTA, MTBF analysis method can be used to build autonomous maintenance, preventive maintenance and reliability centered maintenance so as to facilitate the production and maintenance in determining the proper maintenance of the machine.

Quality control is an effort to increase customer satisfaction and minimize damage. Super Absorbent Polymer which is a product as a raw material for making baby diapers / elderly and sanitary napkins. In Super Absorbent Polymer, defects usually found in the colour contamination that there is a dark colour on the product, print labels mistakes and packaging defects. This study aims to determine the value of DPMO and sigma level, identify the efforts which is taken to reduce disability, identify the types of disability, and find the main factors causing disability. Six Sigma method is used to analyze data with define, measure, analyze, improve and control. The quantitative data obtained by direct observation of quality problems. By using the method of six sigma can be seen that the quality of the resulting product is quite good that is 3.07 sigma with a damage rate of 58,624 for a million production (DPMO). The three highest defect product causes are color contamination of 93.34%, misprint of 3.55%, and packaging damage as much as 3.11%. The main factor causing defects is the engine factor for the type of colour contamination defect,. The type of improper defects in the packaging labels and main factor for the packaging defects is the human factor.kecacatan rusaknya kemasan faktor utama ialah faktor manusia.

PT. X is a distributor of spare parts with 128 customers for Surabaya City and Sidoarjo City. Number of delivery vehicles owned by PT. X is 15. Determination of delivery route owned by PT. X is completed manually based on driver experience. This research is to make a model of determining the route with minimum cost by considering the travel time and the capacity of the vehicle. Model formation is accomplished in accordance with the PT X policy that each colleague can only be served by one vehicle and the maximum shipping time of 7 hours. The model formed is Heterogeneous Fleet Vehicle Routing Problem with Time Windows (HFVRPWTW). The settlement method used is Evolutionary Algorithm (EA) by reviewing 3 cases. The number of vehicles decreased by the model is with an average difference of 1.67 vehicles. The shipping cost generated by the model is lower than the company for case 1 of 3,155 IDR and case 2 of 25,005 IDR. This condition indicates the model will use less number of vehicles with low shipping costs and large container utilities in 2 cases.

Work related accident is a problem that needs to be considered seriously in Indonesia. The number of occupational accidents is increasing significantly from 96,314 in 2009 to 110,285 in 2015. The mortality rate in these cases is very high. This research aims to develop a daily fitness for duty index as a measurement to ensure that workers are able to work effectively and safely. Systematic literature review had been carried out through several stages, i.e. 1) determination of searching strategy, and searching process, 2) determination of searching criteria, 3) quality control for literature, and 4) conclusion. The experiment involved four participants. They divided into two groups: night shift workers and morning shift workers. Total sleep time, heart rate at rest, reaction time, and body weight were recorded during the experiment. The daily fitness for duty index has been developed that consider sleep sufficiency factor, circadian cycle misalignment factor, and individual factor. The daily fitness for duty index has a strong correlation with subjective work readiness measurement. Therefore, it can be concluded that the daily fitness for duty index is trustworthy to measure fitness for duty.

The quantity and quality of coal affects the efficiency of the generating unit, therefore the utilization of Transfer Conveyor 17A is very necessary to fulfill the fuel requirement (coal) of PT Indonesia Power Unit Generation Unit Suralaya. Transfer conveyor is an additional element in a conveyor belt circuit that serves to channel coal from unloading area until coal bunker (power plant). This study aims to find out the value of OEE Transfer Conveyor 17A which is used as the basis of proposed improvement based on the lowest value of the three parameters in OEE. The concept of research adopting OEE method with the value of quality is assumed 97,50% because the equipment that becomes the object of research does not produce the product. The result of calculation obtained by OEE value equal to 82,98% with ratio Availability 86,76% Performance Eficiency 98,09% and Rate of Quality 97,50%. A planned maintenance action is required to avoid unpredictable engine damage such as the operator checking the machine before it is operated, providing periodic training to operators and maintenance to improve their capabilities.
