The consumption pattern of the people in Indonesia is experiencing a shift. Consumption patterns that are influenced by socio-cultural factors today make people tend to consume food and drinks that are practical and easy to obtain. This pattern began in 2014 until now, making the percentage of food consumption increase by 2.5% per year. Bread is a finished food whose demand pattern has also increased. Due to the development of the middle-class population, an increase in the income of young people, and society's consumption pattern, which is increasingly shifting to a practical urban consumption pattern. The bread industry in Indonesia is still classified as the small and medium enterprises (SME) sector. Small and medium enterprises (SME) is a business sector with a significant impact on improving the economy in developing countries. The products are distributed to offices that work with bakeries and are sold in stores. This shows that the shop production must work quickly to meet consumer demand in the surrounding area. In fulfilling consumer demand, a production quality control process is required in the workstation to reduce defective products. This study aims to carry out a quality control process to reduce faulty products by using a control chart and the concept of kaizen to control and maintain the production process in bread SMEs so that quality and work effectiveness can be realized.

PT. Intan Ustrix that's placed at Jl. Raya Roomo No.425, Sekarsore, Roomo, Kec. Manyar, Kabupaten Gresik Indonesia is a company engaged in the paper and cardboard business, and has many machines used in the manufacturing process. The load of the induction motor will make the cost lower, thereby increasing the current cost through the device inside the carton production unit. Fixing the cost of cos is a great way to solve this problem. In this case, it is very important to install a capacitor bank to recover the charge. By installing a capacitor bank will affect the overall performance of the motor used. The cause of this research is the increasing cost of boarding at the cardboard production unit of PT. Intan Ustrix. As an evaluation, capacitor banks are installed on the H200, AFG, 6PA, FM, and 6PS buses so that low cos costs can be increased. The final result of this charge shows that increasing the cos cost at full load of 325 KW from 0.716 to 0.872 can reduce the actual power cost (S) from 396 KVA to 329 KVA, which can maintain 65 KVA and today's decrease (I) from 498 A to 410 A, the lower the current consumption price of the motor used can increase the resistance of the device to the carton production unit.

The Memorandum of Understanding (MoU) at Universitas Darussalam Gontor (UNIDA) is an important activity that can be proven by the number of MoUs that have been carried out. However, because the management of the MoU is still manual, there is a risk of damage, loss, and duplication of the MoU data. In this research, an information system for the Bureau of Cooperation, Alumni, and International Affairs UNIDA has been built to meet the bureau's needs in managing data correctly so that students and lecturers can utilize the data. The system is made in the form of a website using the concept of Model-View-Controller (MVC) and Single Page Application (SPA) by applying the SDLC (System Development Life Cycle) methodology. The study results show the satisfaction value of the respondent's assessment is at 4.11 on a scale of five, which means that this information system provides satisfaction to users. In the subsequent project research, this system can develop an authentication site for user security.

Stroke is a cardiovascular (CVD) disease caused by the failure of brain cells to get oxygen supply to pose a risk of ischemic damage and result in death. This Disease can detect based on the similarity of symptoms experienced by the sufferer so that early steps can be taking with appropriate counseling and treatment. Stroke detecting requires a machine learning method. In this research, the author used one of the supervised learning classification methods, namely K-Nearest Neighbor (K-NN). K-NN is a classification method based on calculating the distance to training data. This research compares the Euclidean, Minkowski, Manhattan, Chebyshev distance models to obtain optimal results. The distance models have been tested using the stroke dataset sourced from the Kaggle repository. Based on the test results, the Chebyshev model has the highest levels of accuracy compared to the other three distance models with an average accuracy value of 95.49%, the highest accuracy of 96.03%, at K = 10. The Euclidean and Minkowski distance models have the same level of accuracy at each K value with an average accuracy value of 95.45%, the highest accuracy of 95.93% at K = 10. Meanwhile, Manhattan has the lowest average compared to the other distance models, which is 95.42% but has the highest accuracy of 96.03% at the value of K = 6

People want energy to satisfy their each day needs. However, maximum of those energy customers are now no longer aware that using an electric powered load is too large, which regularly reasons disturbances. In coping with overload disturbances withinside the family sector, MCB is used as a protection tool. The running precept of the MCB continues to be the usage of magnetic, so it's far less effective. When disconnecting the cutting-edge because of overload, the MCB will experience a touch overdue, which could reason sparks and a hearthplace withinside the family. Therefore, on this look at a cutting-edge sensor protection circuit is designed to update the MCB. This circuit can show the cutting-edge cost at the LCD and restriction the overcurrent to a restriction of three amperes. The overload safety machine constructed from the ACS712ELC-5A cutting-edge sensor can come across currents among 0A and 5A. So, to reduce off the cutting-edge, a 12V relay is used. When trying out a ready-made machine, this protection tool can study currents withinside the variety 0A to 3A, with median studying mistakes of 0.65%. If the burden is better than 3A, the machine also can reduce the cutting-edge.
