Misdiagnosis results in inaccuracies in the provision of solutions and actions. Initial treatment that corresponds to the complaints of pregnant women especially the third trimester is expected to reduce mortality rates in the mother and fetus. Expert System can be a timely solution with not too long so as to improve the quality of examination on midwives. The methods used are identification, primary and secondary data collection, forward chaining data analysis combined with bayesian, and evaluation with the calculation of the percentage of system success. Samples taken by 20 patients and 4 patients were declared unsyed because they had only one complaint. Meanwhile, 16 patients had some complaints that complied with the Rules. A total of 11 out of 16 patients or about 70% had valid results between the diagnosis of experts/midwives with the system. It can be concluded that the system works well to diagnose complaints in patients with a third trimester gestational age so that midwives can provide appropriate initial solutions and treatment in reducing maternal and infant mortality.</p> Embun Fajar Wati, Anggi Puspitasari Copyright (c) 2020 Embun Fajar Wati, Anggi Puspitasari https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10593 Sat, 03 Oct 2020 00:00:00 +0700 Implementation of Apriori Algorithm Data Mining for Increase Sales https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10587 <p>Any company or organization that wants to survive needs to determine the right business strategy. The product sales data carried out by Lakoe Dessert Pondok Kacang will eventually result in a pile of data, so it is unfortunate if it is not re-analyzed. The products offered vary with a wide variety of products as many as 45 products, to find out the products with the most sales and the relationship between one product and another, one of the algorithms is needed in the data mining algorithm, namely the a priori algorithm to find out, and with the help of the Rapidminer 5 application, with a support value 2,4% and a confidence value 50%, products that customers often buy or are interested in can be found. This study used sales data for March 2020, which amounted to 209 transaction data. From the research, it was found that the item with the name Pudding Strawberry and Pudding Vanilla was the product most purchased by consumers. With knowledge of the most sold products and the patterns of purchasing goods by consumers, Lakoe Dessert Pondok Kacang can develop marketing strategies to market other products by analyzing the profits from selling the most sold products and anticipating running out or empty of stock or materials at a later date.</p> Reza Alfianzah, Rani Irma Handayani, Murniyati Murniyati Copyright (c) 2020 Reza Alfianzah, Rani Irma Handayani https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10587 Sat, 03 Oct 2020 00:00:00 +0700 Drug Stock Prediction at Balige HKBP Hospital Using Adaptive Neuro-Fuzzy Inference System https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10529 <p>Currently the purchases of drugs at Instalasi Farmasi RSU (IFRS) HKBP Balige are based on the examination of the amount of drugs usage. The purchases of drugs based on the examination of the amount of drugs usage cause frequent unplanned drugs purchases that must be hastened (cito) and purchases to other pharmacies. The purchases of cito and purchases to other pharmacies will inflict a financial loss to the patients, because when IFRS makes drugs purchases of cito or to other pharmacies, the cost of the drugs will be more expensive. Therefore, in this research, a prediction of drugs stock in IFRS HKBP Balige using Adaptive Neuro Fuzzy Inference System (ANFIS) will be carried out. ANFIS is a combination of Least Square Estimator (LSE) and Error Back Propagation (EBP) algorithms. ANFIS consists of forward pass and the backward pass learning. The sample data used to predict drugs stock in this research is data of drugs sales at the IFRS HKBP Balige from 2013 to 2015. From the results of drugs stock prediction research with ANFIS, obtained that number of errors of ANFIS model is 5.52%. Based on MAPE accuracy level evaluation, number of errors have an excellent rate so that it can be concluded that the predicted results of the drugs stock are good.</p> Arie Satia Dharma, Lily Andayani Tampubolon, Daniel Somanta Purba Copyright (c) 2020 Arie Satia Dharma https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10529 Sun, 13 Sep 2020 00:00:00 +0700 The Implementation of Artificial Intelligence in Charity Box at Mosque and Musholla as RFID Based Security System https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10594 <p>The high crime rate in Indonesia has had a bad impact and loss on society, so that various efforts have been made to increase awareness and security in society. Charity box theft is a target of crime for criminals. For this reason, it is necessary to take strict steps in terms of vigilance and security so that the crime of theft of charity boxes can be avoided. One of the steps to increase awareness and safety is to apply the concept of security to the charity box. By utilizing several supporting sensors and supporting components in the charity box, the security system will work automatically, so that if there is a charity box theft, the system will provide an SMS notification to the mosque management. This research is focused on the problem of security facilities and supervision of charity boxes in mosques or mushalla. Using this system will reduce the risk of theft of charity boxes in mosques and mushalla, because apart from being equipped with an alarm and SMS gateway, this system is also equipped with RFID so that access to open charity boxes can be safer. This form of system works if the charity box is lifted or dismantled by force, the system will provide notification in the form of an alarm and SMS, so that the crime of theft of the charity box can be more aware of.</p> Defnizal Defnizal, Risa Nadia Ernes Copyright (c) 2020 Defnizal Defnizal, Risa Nadia Ernes https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10594 Mon, 05 Oct 2020 00:00:00 +0700 Facial Recognition Implementation using K–NN and PCA Feature Extraction in Attendance System https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10612 <p>Attendance is the fact that someone is present at an event or goes regularly to an institution, or attendance at an event is the number of people present at that time. The Saifiatul Amaliyah school itself is one of the many schools in Indonesia where the attendance of students or attendance is still done manually. This can cause problems, namely allowing fraud when filling in attendance and errors in data recapitulation. Therefore, in this study a computerized face attendance was created, which was formed using the K-Nearest Neighbor (K-NN) method and combined with the extraction of the Principal Component Analysis (PCA) feature where the attendance process can be done with a person's face. The face attendance system using the K-NN and PCA methods has an accuracy of 82%.</p> Juliansyah Putra Tanjung, Bayu Angga Wijaya Copyright (c) 2020 Juliansyah Putra Tanjung, Bayu Angga Wijaya https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10612 Thu, 01 Oct 2020 00:00:00 +0700 Data Mining Model For Designing Diagnostic Applications Inflammatory Liver Disease https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10589 <p>Hepatitis is an infectious disease that is a public health problem that affects morbidity, mortality, public health status, life expectancy, and other socio-economic impacts.

In addition to the marketing strategy, the company must be able to analyze the products sold based on the number of sales that have occurred so that the company can see which products are more dominant in consumer demand so that the company can determine a more effective sales strategy. PT. Surya Indah City is a company engaged in the sale of various clothing and accessories. In an effort to increase sales of its products, an analysis is needed to be able to increase company revenue by utilizing sales transaction data it has. To analyze the relationship between clothing products and accessories which are more predominantly sold and other available clothing and accessories products, a data mining algorithm is used, namely the a priori algorithm. With the help of the tanagra application to carry out the calculation process, the dominant product that consumers are interested in can be determined. By using two variables that meet support and minimum confidence, it can be concluded that the most sold products are from the type of clothing, namely clothes and pants. It was concluded that the results of the known final association rules, if you buy a shirt, you will buy pants with 50% support and 75% confidence. If you buy pants, you will buy clothes with 50% support and 85% confidence.</p> Jarseno Pamungkas, Yopi Handrianto Copyright (c) 2020 Yopi Handrianto https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10599 Wed, 07 Oct 2020 00:00:00 +0700 Designing an Arduino-based Automatic Cocoa Fermentation Tool https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10611 <p>Automatic cocoa fermentation design is expected to facilitate the work of cocoa farmers during the process of reversing and stirring cocoa fermentation based on the right temperature. The fermentation process is of course done in a box or sack so that chocolate quickly produces heat and is cemented. However, in certain conditions, especially when in sacks there are often obstacles in the stirring process. Often the fermented chocolate experiences weathering or moldiness due to the uneven reversal that causes chocolate to clot, causing weathering or moldiness and produce an unpleasant odor and unattractive color on the cocoa beans. To overcome this problem a tool that automatically can turn or stir the cocoa beans evenly. This device is controlled by Arduino Uno R3 with a sensor that is an LM35 temperature sensor and has an LCD output and DC motor. This tool uses Relay to adjust the delay when driving a DC motor. The working principle of this tool, when the LM35 temperature sensor receives heat conditions on the cocoa beans, the LCD will display the condition of the temperature while the relay will instruct the DC motor to move the Cocoa Fermentation rail rotating left or right. The purpose of making this tool is to create a tool that can help alleviate the work of cocoa farmers in cocoa bean stirring activities at the time of cocoa bean fermentation controlled by Arduino. From the results of the tests carried out, the tool is able to read both hot and cold temperature conditions, and the LM35 sensor can work well in detecting temperature changes from 350C to 400C or vice versa.</p> Balkhaya Balkhaya, Dirja Nur Ilham, Rudi Arif Candra, Hasbaini Hasbaini, Fera Anugreni Copyright (c) 2020 Dirja Nur Ilham https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10611 Thu, 01 Oct 2020 00:00:00 +0700 Design of an Automatic Water Pump on a Traditional Boat https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10635 <p>Draining traditional boat water efficiently is sometimes considered to be of little importance to most fishermen. Because it is considered a normal thing without realizing it can be detrimental, both in terms of time and work. One of the things that often makes the use of draining water less efficient is that the draining of boat water is still done manually with human intervention. So that fishermen are preoccupied with removing puddles of boats and hindering their work. Based on the above problems, this study aims to make a traditional boat water drain control system automatically. This tool functions to control the volume of water in the boat as well as turn on and turn off the water pump engine automatically. This tool is able to remove puddles that enter the fishing boat automatically. The working principle of this tool, if the water hits the sensor ≥ 5 cm, the pump and buzzer will start and if the water doesn't hit the sensor, the pump and buzzer will automatically shut down.</p> Ihsan Ihsan, Dirja Nur Ilham, Rudi Arif Candra, Amsar Yunan, Hardisal Hardisal Copyright (c) 2020 Dirja Nur Ilham, Ihsan Ihsan, Rudi Arif Candra, Amsar Yunan, Hardisal Hardisal https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10635 Thu, 08 Oct 2020 00:00:00 +0700 Sentiment Analysis Of Full Day School Policy Comment Using Naïve Bayes Classifier Algorithm https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10564 <p>Sentiment analysis is an important and emerging research topic today.

To provide additional capital loans, there are several requirements that must be met by every UMKM. Like an independent business that is carried out, whether it is permanent or only limited to domicile, then how long have they started the business they have built up to now, do they have collateral as loan guarantee, do they have a good level of business productivity during the running, seen from the report made, do you already have a lot of customers from the business you run. This is a benchmark for providing loans to UMKM. The method that can be recommended is Promethee, which is part of the Multi-Criteria Decision Making (MCDM) concept as a rating method in determining loan issues recommended by the Promethee method. The results obtained from the ranking with the Promethee method, namely that of the six selected and evaluated UMKM, the first rank was from the UMKM-3 with the highest weight value of 0.208, followed by UMKM-1 with a weight of 0.042 and followed by UMKM-5 which were still considered feasible even though they were not valuable. negative, while the other two UMKMs cannot be said to be eligible for a loan, namely UMKM-2 and UMKM-4 because they are negative.&nbsp;&nbsp;&nbsp;&nbsp;</p> Akmaludin Akmaludin, Erene Gernaria Sihombing, Linda Sari Dewi, Rinawati Rinawati, Ester Arisawati Copyright (c) 2020 Akmaludin Akmaludin https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10603 Thu, 08 Oct 2020 00:00:00 +0700 The Infusion of Notification Design With an Application of Social Media Based on a Internet of Things (IOT) https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10610 <p>This study discusses the infusion detection device in a hospital room.

We also work together with Dinas Pekerjaan Umum dan Penataan Ruang of Kabupaten Kubu Raya, as they are managing nearest irrigation land which available to be inspected for research. The system has been tested in a real-life case study. As a result, the system enhances the efficient management of irrigation area and infrastructure data. Users stated that this geographic information system has many benefits to irrigation area management., i.e, ensuring data authorization with user information when data is recorded, real time image capture for each irrigation infrastructure, and digital maps to gain a wide overview of irrigation area information on Kabupaten Kubu Raya</p> Rachmat Wahid Saleh Insani, Syarifah Putri Agustini Copyright (c) 2020 Rachmat Wahid Saleh Insani, Syarifah Putri Agustini https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10620 Mon, 12 Oct 2020 00:00:00 +0700 Web-Based Desktop Support Trouble Ticket System Design In PT. Mnc Mediacom Cable https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10570 <p><em>In recent years the existence of web-based information systems in Indonesia has increasingly felt its presence in supporting daily activities, both economic and non-economic. Manually processing data certainly cannot keep up with the need for fast, precise, and accurate presentation of information. Currently, manual data processing is considered less effective for providing reports and information for companies that are developing and have diverse transactions. The importance of Trouble Ticket Desktop Support is to make equalization of workloads that are fair and balanced besides that it is also a tool for assessment on each a technician. So with this, the author tries to examine the application of web-based technology that can be applied to problems that exist in one activity so that it can integrate the activities concerned. Ticket Desktop Support as a process to collect data from various existing sources and Desktop Support is required to be active monitor and treat user needs. With Trouble Ticket Desktop Support that is well integrated so that accessing data on Desktop Support can be done easily and quickly in order to measure the level of problems and access reports by the Head of IT Operations, as well as problems can be handled well within the scope of problem boundaries that produce the right solution to manage resources the power available, with this application it will be clear what problems are faced by the customer.</em></p> Besus Maulana Shulton, Eva Zuraidah Copyright (c) 2020 Besus Maulana Shulton, Eva Zuraidah https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10570 Thu, 01 Oct 2020 00:00:00 +0700 Period Study Accuracy Prediction using Sequential Minimal Optimization Algorithm https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10621 <p>The study period is quite influential in the assessment of a university. The imbalance in the ratio of students to lecturers causes the quality of teaching and learning to decline, this is because one lecturer has to manage many students. Acquisition of accreditation scores and society's assumptions about higher education are also strongly influenced by the number of student graduations on time. Therefore, the prediction of the accuracy of the study period is needed as consideration for related parties to solve the problem of student learning delay. Sources of data in this study were taken from a database stored at the University of Surakarta, namely the Temporary Achievement Index with data of 209 instances and 5 attributes. The proposed method in this study is the Sequential Minimal Optimization algorithm. The validation method uses k-fold Cross-Validation with a value of K = 10. This method is compared with other methods such as naive Bayes, KNN, and Decision Tree. The results of this study, the proposed method can predict the accuracy of the study period quite well with the acquisition of accuracy of 88.52%. However, several other methods such as NaiveBayes obtained better accuracy of 90.91%, KNN of 91.86%, and Decision Tree of 96.65%. From the results of the comparison of these methods, the Decision Tree obtained the highest accuracy value. In future studies, researchers aim to enrich features in the prediction process. These features are related to student activities, such as student backgrounds, social activities, additional activities on campus and off-campus, and other aspects.</p> Hendri Noviyanto, Bayu Mukti Copyright (c) 2020 Hendri Noviyanto, Bayu Mukti http://creativecommons.org/licenses/by-nc/4.0 https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10621 Thu, 15 Oct 2020 00:00:00 +0700 Twitter Comment Predictions on Dues Changes BPJS Health In 2020 https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10588 <p>The Social Security Administering Body (BPJS) is a facility established by The government in providing services to citizens in The field of health welfare. The Spirit of cooperation in the utilization of health services which is very much currently a constraint in the budget is still insufficient in covering health services as a whole. For this reason, government policy is following with PERPRES No. 75 in 2019, the Government officially raised the BPJS Health contributions for 2020. The increase in BPJS Health contributions certainly caused a lot of comments. Namely Twitter, one of the social media that is used by the public to express disapproval or support for this government policy. This study, testing was carried out related to the prediction of comments from social media on community responses to the increase in BPJS Health contributions taken by the government. In the test carried out 3 (three) input algorithms. For every single algorithm including getting results through the K-NN method with an accuracy of 71.83% and AUC value of 0812, for the Naïve Bayes method produces an accuracy of 81.63% and AUC value of 0586. As for the C 4.5 method, the accuracy is 65.37% and the AUC value is 0628. While testing conducted through the Ensembles Vote method which combines the 3 algorithms above gives the best results with an accuracy of 80.10% and AUC value is 0871 for Twitter comment predictions.</p> Riza Fahlapi, Yan Rianto Copyright (c) 2020 Riza Fahlapi, Yan Rianto https://jurnal.polgan.ac.id/index.php/sinkron/article/view/10588 Tue, 20 Oct 2020 00:00:00 +0700
