Varia Usaha Beton provides concrete products. On the concrete production line in Gresik, the company makes various types of concrete, one of which is precast concrete. In manufacturing activities, there are problems when carrying out production where there are orders whose production has not been fully realized. Aspects of workload can influence production demand which cannot be realized in its entirety because workers expend too much energy resulting in workers not being optimal and the limited number of workers resulting in demand not being met. To address this problem, researchers conducted a workload analysis on precast concrete production activities for each product and determined the number of workers needed according to production demand. The method used is using working time measurements and the Full Time Equivalent method to analyze workload and determine the number of workers according to the FTE value index. The results obtained after data processing and data calculations were carried out for operators working to produce precast concrete, 13 of which were overloaded and 2 of which were normal. After calculating the need for workers, the workers needed to meet the demand for precast concrete production requires 52 workers from the initial 24 workers.</em></p> <p><strong><em>Keywords:</em></strong><em> Full-Time Equivalent, Workload, Worker Needs</em></p> Wahyu Rahman Dani Jaka Purnama Copyright (c) 2024 http://creativecommons.org/licenses/by-sa/4.0/ 2024-04-22 2024-04-22 8 2 196 204 10.37090/indstrk.v8i2.1217 Pengendalian Kualitas Produk Part Grip Model D55L Dengan Pendekatan Six Sigma Di PT.Z https://jurnal.utb.ac.id/index.php/indstrk/article/view/1194 <p><em>The existence of the Industrial Revolution 4.0, progress, and developments over time are starting to change the way consumers view a company.

The higher the population of a country, the more it will affect the balance of that country. This research aims to predict the national population using the Artificial Neural Network (ANN) approach. The sample for this research is population data for each province obtained from the National Central Statistics Agency (BPS). The data is iterated from 2011 to 2022. The approach method uses backpropagation Artificial Neural Networks (ANN). The architectural model is determined with 2 hidden layers and 1 output, namely 5-20-10-1 with learning rate variations of 0.01, 0.02, and 0.03. ANN prediction results are able to predict the national population. The success of the three models shows that the ANN model with a Learning rate of 0.01 has the highest accuracy level of 96.9697, equivalent to 97%. This is proven by the model's success in predicting 32 out of 33 data samples with a time duration of 117 seconds. The prediction results showed that the highest population numbers were in three provinces, namely Central Java, West Java, and East Java. Meanwhile, the lowest population is in West Papua province.</em></p> <p><strong><em>Keywords:</em></strong><em> BPS, JST, Learning Rate, Optimization. </em></p> Misrianto Misrianto Halimah Siregar Copyright (c) 2024 http://creativecommons.org/licenses/by-sa/4.0/ 2024-04-22 2024-04-22 8 2 397 406 10.37090/indstrk.v8i2.1526 Analisis Perawatan Mesin Kapal dengan Metode Reliability Centered Maintenance (RCM) di PT Jasa Armada Indonesia Tbk https://jurnal.utb.ac.id/index.php/indstrk/article/view/1261 <p>Maintenance of the ship is a task aimed at ensuring that the ship continues to operate in a normal and seaworthy condition. This work is related to the ship's machinery system and other equipment on board. If the ship does not receive regular maintenance, it can impact the condition and performance of the ship. By implementing Reliability Centered Maintenance (RCM), information about the steps needed to ensure optimal operation of the engine or equipment can be obtained. RCM is a method used to develop Preventive Maintenance. In Time Directed (TD), there are two components, namely the schottel Asd component and the valve on the cylinder head. In Condition Directed (CD), there are three components found in the three pipe components: fuel pipe, oil, and engine coolant. In Failure Finding (FF), there are four components found in the seachast component, injector pump, fuel filter, and air. Based on the application of the RCM method used, the recommended maintenance actions for the Finding Failure (FF) category include daily, weekly, and monthly inspection activities. Meanwhile, for the Time Directed (TD) category, maintenance actions involve scheduling component replacements based on predetermined intervals.</p> <p>Keywords: FMEA, LTA, Maintenance, RCM</p> Hafiz Azhari Jimmy Greei Ganap Firda Ainun Nisah Copyright (c) 2024 http://creativecommons.org/licenses/by-sa/4.0/ 2024-04-26 2024-04-26 8 2 407 417 10.37090/indstrk.v8i2.1261 Implementasi Metode Single Minute Exchange of Dies Untuk Optimasi Setting Time Mesin Flexo B1 Grup C Pada Carton Box Departement PT.
