Abstract

One aspect of KRI operation readiness is navigation equipment where the navigation radar as a system for detection and location of objects has vital function so that high radar readiness is needed to support operations. To fix or prevent system damage, scheduled maintenance management is needed. The critical components of the Sperry Marine Bridgemaster E Radar were determined using the FMECA and reliability models in this analysis. The Risk Priority Number (RPN) was calculated using the FMECA model and was used as a reference value when evaluating critical components. The Risk Matrix is used to analyze the RPN value of each component. Of the 20 (twenty) components found, 7 (seven) are considered critical. It is a DC motor drive, Interface Unit, Magnetron, Modulator, Power Supply Scanner, Electronic Processor Belt and Drive Belt. With a value of 51840, the DC Motor Drive component has the highest RPN value, while the Dive Belt component has the lowest RPN value of 43776. Modulator has the shortest replacement period of 128 days, while the Processor Electronic Unit has the longest replacement time of 271 days.

Abstract

Work accidents, especially in the industrial world, must be an essential concern because they involve and individual health and safety in the surrounding environment. At Squadron 900 / Fasharkan Puspenerbal Juanda, there were quite a lot of work accidents. The causes of work accidents vary, from mechanical aspects (equipment and machines) to parts of hazardous materials. The use of Hazmat mainly causes work accidents in squadron 900/Fasharkan, primarily in department IV. Therefore in this study only discuss hazardous materials as a cause of work accidents. The research conducted is the identification of risks in department IV ( Department of Frame, AKP and Motor ) Squadron 900 / Fasharkan, especially the Division of Frame and Mechanical Division using the approach of Risk Management System. In this approach, a risk ranking is carried out using FMEA, and further efforts a made to make improvements to reduce the risk of hazards. The improvement efforts- selected from several alternative solutions that have made using the NPV approach. With the Net Present Value approach, it is possible to compare the existing alternative solutions financially. Keywords: Risk Management, Occupational Health and Safety (K3), Hazardous materials, Net Present Value (NPV)

Abstract

Currently, various technologies are being developed which aim to improve the oxidation process so that its pollutant byproducts can be reduced. One of them is the development of the use of ozone as an alternative oxidizer which in the organic chemistry perspective has more free electrons so it is more reactive than oxygen. Ozone can be produced through several methods, such as the electrolysis method, the incandescent electrode method and the high voltage electrode method. This study aims to measure the feasibility of an ozone-producing reactor based on the high-voltage electrode method to produce photon strips initiating the formation of oxygen radicals. As the main indicators of the feasibility is the efficiency and level of performance of the reactor in producing ozone. As a comparison, the reactor is based on the previously made incandescent electrode method. Based on data from experimental results in the laboratory it can be shown that the high voltage method reactor is quite feasible. It can be proven in the discussion and analysis using linear regression and Minitab software that this method provides an increase in efficiency of 0.5% (0.714% to 1.214%) and an increase in performance of 1.8 ppm / min (2.57 ppm / min to 4, 37 ppm / minute ozone gas can be produced from 2.4 L / min of atmospheric air flowed into the reactor tube). Keywords: Laboratory Experiment, Application, ASTM D-2912, Linear Regression and Minitab Software, Product Feasibility.

Abstract

The ability to carry out the maintenance and repair of Warships of the Republic of Indonesia / naval vessels is a concept used in assessing the achievement of work with time parameters and measures of success. Budget, infrastructure and human resources have an important role in the task of maintenance and repair facilities surabaya. Every maintenance and repair always expects the implementation of the work to be completed on time, and the maximum results, so that the ability to maintain and repair needs to be maintained and improved on the implementation of the work. There are several alternative factors that can lead to improved maintenance and repair capabilities of warships of the Republic of Indonesia / Naval vessels including budget allocation, supporting infrastructure directly or indirectly as well as the readiness of human resources that include willingness, experience and expertise. These factors have an interconnected pattern. This study aims to find out the main factors that affect the improvement of the ability to maintain and repair KRI / KAL in mako koarmada II. In this study used a measuring instrument called dynamic system method with stella software. Factors that affect the improvement of capabilities in the literature can be from the literature whereas, the determination of the main factors that affect is done by modeling dynamic systems. This dynamic system modeling is done by creating a dynamic relationship between the factors that affect productivity. The data collection in this study uses secondary data from the process of maintenance and repair of fasharkan in Surabaya. The scale of the data used to determine the factors that influence the improvement of the ability is modeled in qualitative form. The result of modeling dynamic system factors that affect the improvement of capability is budget, infrastructure facilities and human resources factors that dominate are human resource factors. Keywords: Proficiency, Dynamic System, Stella Software
