<![CDATA[PT. XYZ Indonesia is a state-owned company operating in the ship industry located in Surabaya, Indonesia. PT. XYZ produces merchant ships, warships, and general engineering projects. At PT. XYZ, there is a PMO (Production Management Office) division which has a job description to organize and analyze the schedule required to complete a shipbuilding project. This research uses the PERT (Program Evaluation and Review Technique) method which is used to determine 3 durations, namely optimistic duration, pessimistic duration, and the most likely duration to occur in the machine auxiliary sub-work process on the X ship. Of course PT. XYZ also prioritizes quality and timeliness in completing his projects, so that the name of PT. Friends, you can compete on a national and international scale in the shipping industry. Therefore, this research aims to determine the most effective schedule both in terms of cost and time. The data needed in this research is the master schedule data for the X ship project. In the research that has been carried out, it was found that the processing time of the auxiliary machine is 271 Day. Thus, the conclusion obtained from this research is that schedule analysis using the PERT method has more effective results compared to predetermined planning.]]>

<![CDATA[Bridge cracks are gaps that form on the concrete surface of the bridge due to the aging process or the load exceeding its capacity. Knowing the cracks in the bridge is very important because undetected cracks can cause serious damage to the bridge structure, threaten the safety of road users, and increase the cost of maintaining and repairing infrastructure. Fractal analysis is a mathematical approach that studies structures and patterns in complex and irregularly shaped objects. This study aims to apply fractal-based analysis using fractal dimension and lacunarity features in classifying image cracks on the surface of concrete bridges. By using fractal analysis and the K-Nearest Neighbor classifier, this study succeeded in achieving an accuracy of crack image classification on concrete bridges of 97.6%, followed by precision and recall values of 97.659% and 97.6%. These results prove the potential of fractal analysis as an effective method for detecting cracks in concrete bridges and can make an important contribution to the maintenance and safety of bridge infrastructure in the future.]]>

Thus, the purpose of this study is to help control excess inventory and reduce costs as low as possible. The method used in this study is Just in Time (JIT). Therefore, this study resulted in a difference in the estimated cost of storing raw materials every month before using JIT of Rp. 15,269,335 while the estimated cost of storing raw materials per month after using the Just in Time system was Rp. 7,634,667 so as to reduce the estimated cost of storing raw materials by Rp. 7,634,667. Therefore, the use of Just in Time can increase productivity by controlling the inventory.]]>

<![CDATA[The Google Sites application is an interactive multimedia which is one of the products of the Google company as a means of creating a site equivalent to a website. Biology is a science that is dominated by theory and is closely related to memorization and reading. So, in its application it requires good focus on the material being presented. One innovation that can be done is by designing interactive and creative learning media such as Google Sites. The Google Sites application is designed in the form of presenting learning material on the topic Biology of the Human Reproductive System as an effort to develop learning media and enrich creativity during learning. However, when developing learning media, of course you have to guarantee quality, performance and functionality, therefore it is important to test the system before the learning media is handed over to students. The aim of this research is to test Google Sites-based learning media using the black box testing method. Black box testing is a test that only tests the functionality of the system, in this case it only tests the input and output produced by the system. After black box testing was carried out, Google Sites based learning media was suitable for use with results that met expectations.]]>
