This paper presents a Monte Carlo simulation to determine the reliability and availability of boiler critical components in a steam power plant. The Monte Carlo simulation results are expected to be a reference for maintenance and repair times that will be used in the future. Steam power plant is one in every of the foremost wide used power plants in Indonesia, and one of them is located in Nagan Raya Regency, Aceh, Indonesia. Nagan Raya steam power plant has an installed capacity of 2x110 megawatts. The highest failure frequency is found in the boiler, this is reflected in the high downtime. Performance in terms of reliability and availability needs to be evaluated to minimize these failures. Monte Carlo simulation is used as an evaluator to increase the reliability and availability of performance by predicting failure time and repair time (TTF and TTR) for each critical component of boiler part. Monte Carlo simulation uses random numbers with a uniform distribution (0 to 1) generated from generating random numbers, then converting them to non-uniform distributions using the inverse transformation method. Monte Carlo simulation will be carried out on eight critical components of the two boiler units at Nagan Raya steam power plant. Monte Carlo simulation results on eight critical components of the boiler obtained a reliability value of 30% to 42% with TTF at 260 hours to 1.312 hours, a reliability value of 22% to 41% with TTR at 1,57 hours to 2,26 hours, and the average availability value is above 99%.

Shipyard is a specialized facility equipped with various tools to support the process of building, repairing and maintaining ships. There are several types of variant ships, such as military ships, tourist boats, cargo ships and passenger ships. Apart from being a place for shipbuilding, shipyards are utilized to conduct several activities, such as ship design, equipment installation, plate installation, feasibility tests and classifications. There are many production activities and production flows that allow for potential waste problems that have an impact on labor usage, product quality, costs, and production time. The aim of this research is to identify waste in shipbuilding production lines through a lean manufacturing approach. The lean manufacturing approach is one of the ways in shipyards to observe the level of waste in the production process, so that it can reduce unnecessary activities in the production process which can increase production efficiency and effectiveness. This study approach begins with the identification of waste in the production line through mapping on each line so that activities that have no added value are identified. Based on the results of identification using the waste assessment model (WAM) method which consists of a waste relationship matrix (WRM) and a waste assessment questionnaire (WAQ), waste is obtained namely inventory (27,20%), overproduction (20.24%), defective products (20.04%), motion (12.47%), transportation (9.23%), waiting time (7.46%) and process (3.37%).

Traditional ships are currently experiencing a significant demand in proportion to the increasing number of fishermen using traditional boats in West Aceh District, Indonesia. However, shipbuilders experienced many obstacles during the manufacturing process, therefore the quality of the ships produced was not in accordance with the standards or the demand of the ship owners. Imperfections in the form of defects on the ship are often found when the ship has been completed. The purpose of this study is to solve the problem of defects that occur in the traditional shipbuilding process in Aceh Barat District, Indonesia. Solving these problems is expected to improve the quality of the ships produced. The initial identification process using Failure Mode and Effect Analysis (FMEA) will be carried out to determine potential defects that can affect the quality of the ship. Defects that pose a high risk to the quality of the ship were resolved using a Logic Tree Analysis (LTA) in order to obtain recommendations for improvements. Based from the results, four risks of damage have been identified that affect the quality of the traditional ships produced, namely; the selection of the quality of raw materials, imperfect wooden joints, easily corroded steel bolts, and poor installation of additional equipment. There are several actions that can be used, among others; replacement of damaged components, reconnection, hot dipped galvanized bolt replacement, and repair the installation of additional equipment.

The observance of ultramodern developments in view, amalgamation digital, and physical systems will be convincing to a revolution. Universities are required to add to their approach and methods of educations. The latest technologies such as Artificial Intelligence, Cloud Computing, Big Data Analytics, Internet of Thing, Augmented Reality and other advancements need to be the focus for a student to learning its application. This paper based on qualitative research provided by deductive process with an approach focused on curriculum redesigning and teaching the practice in lines with Industrial Revolution 4.0 practices. This research is performed to analyze the dominant aspect of Industrial Revolution 4.0 and highlight the focused areas to be studied by universities while updating and designing their inline curriculum with a revolution upcoming. Based is upon the above-contented analysis and after evaluating terminologies, a curriculum must fulfill proposed an analysis of big data, augmented reality, internet of thing, artificial intelligence, and cloud computing.

PT. Cahaya Intan Bersaudara is a company engaged in transportation services in the Meulaboh area of West Aceh Regency which has 10 land transportation routes from Meulaboh Banda Aceh, Meulaboh-Lhokseumawe, Meulaboh-Takengon, Meulaboh-Langsa, and Meulaboh-South Aceh. Based on the results of preliminary observations made, one of them is that transportation service providers for the community are still unable to meet the quality of service desired by transportation service users where transportation users feel complaints about the quality of transportation services provided such as being late in picking up customers, unfriendly drivers, comfortable seating less, driver behavior while driving is less control, cleanliness in the car is lacking, the level of security in the car is lacking. The purpose of this study is to determine the value of the factor of passenger needs for improving the quality of services provided, determine the service attributes that significantly affect passenger satisfaction with the service quality approach, determine the level of passenger satisfaction with the services provided using importance performance analysis. Overall using the service quality attribute method has an average gap score of 0.25. From the results of this study, it was found that the average level of conformity was 78.01%, while the average value of each attribute of interest was 73.25% and the average satisfaction was 74.14% consisting of 20 attributes obtained.
