Abstract

Gangguan pada jantung terus meningkat dan menjadi penyakit yang mematikan. Perlunya diagnosis secara dini terhadap penyakit ini, namun hal itu sangat sulit dilakukan. Hal ini dikarenakan kurangnya tenaga ahli medis yang terlatih dan sumber daya lain yang dibutuhkan untuk melakukan diagnosis dan perawatan yang tepat bagi pasien penyakit jantung. Proses evaluasi menggunakan hasil prediksi yang akurat terhadap resiko gagal jantung sangat membantu penderita dalam mencegah serangan jantung yang parah dan dapat meningkatkan angka keselamatan dari penderita penyakit ini. Diantara cara yang paling efektif dalam mengidentifikasi dan melakukan prediksi pada penyakit jantung adalah dengan pemanfaatan algoritma data mining. Penelitian ini bertujuan untuk membuat model terbaik untuk prediksi penyakit jantung menggunakan algoritma data mining Decision Tree (C4.5). Berdasarkan hasil penelitian yang telah selesai dilakukan, dapat diambil kesimpulan bahwa nilai akurasi terbaik diperoleh pada model prediksi yang menggunakan perbandingan data training dan data testing sebesar 90%:10% yang menghasilkan nilai akurasi sebesar 88,35%. Model prediksi ini diharapkan dapat menjadi alat pendukung dalam diagnosis penyakit jantung, sehingga dapat dilakukan pencegahan serangan jantung yang parah dan dapat meningkatkan persentase angka keselamatan bagi penderita.

Abstract

Patriot Nusantara Private Vocational High School (SMKS) is an educational institution in Jakarta, Patriot Nusantara SMKS organizes educational assistance programs through scholarships. There are various types of scholarships given, namely scholarships given to underprivileged and high achieving students. The Student Study Assistance Scholarship (BBS) is a type of scholarship for economically disadvantaged students, while the Academic Achievement Improvement Scholarship (PPA) is a scholarship given to high-achieving students. To find patterns in determining scholarship recipients, a decision support system was built, through research. This research uses the Analytical Hierarchy Process (AHP) method. This method is used to evaluate and make multi-criteria decisions. It evaluates various alternatives based on different criteria and assigns a relative score to each alternative. Based on the results of this research, it produces better and more accurate calculations. If previously selection took 10 hours, now with the decision support system the selection time is shorter.

Abstract

Patriot Nusantara Private Vocational High School (SMKS) is an educational institution in Jakarta, Patriot Nusantara SMKS organizes a teacher performance assessment program. In the process of assessing the performance of teachers at Patriot Nusantara Jakarta Vocational School, the conventional method is used by filling out a questionnaire carried out by the school principal and the assessment team, then the questionnaire is summarized. The large number of teachers makes it difficult for school principals and assessment teams to determine the best teacher decisions. To find patterns in teacher performance assessment, a decision support system was built, through research. This research uses the Analytical Hierarchy Process (AHP) method. This method is used to evaluate and make multi-criteria decisions. It evaluates various alternatives based on different criteria and assigns a relative score to each alternative. Based on the results of this research, it produces better and more accurate calculations. If previously selection took 1 day, now with the decision support system the selection time is shorter.

Abstract

The quality of health services is essential to public health center services. One of the influencing factors is the level of patient satisfaction with the services provided. This research aims to predict patient satisfaction at Brangsong I Community Health Center using the C4.5 algorithm and determine the accuracy of the results. The first step is the collection of data which is carried out by the distribution of questionnaires to be completed by patients, then secondly the results of the questionnaire are analyzed for a summary in Excel form. Perform calculations to find the gain and entropy. The results obtained by the service flow obtained the highest gain, which was 0.4974. Then, calculations are performed on the dimensions of the service flow until its completion. The research testing process used RapidMiner software to create a decision tree. The accuracy of the calculation results is 98%. The value of the gain can be influenced by the treatment reserved for the data used during the search. Based on the analysis results, it is hoped that it can improve the performance of Brangsong I Community Health Center by providing better services to patients.

Abstract

The study aims to determine the impact of the Logistic Regression method on the classification of customer bank deposits, using a public UCI Bank Marketing dataset, which contains customer-specific information of bank deposit telemarketing activities. Data has a binomial label consisting of 'yes' for subscribers and 'no' for non-subscribers. The data preprocessing phase is done with downsampling to make the amount of data more symmetrical, then data selection and data transformation to ensure that the data used values are consistent, attribute selection to select the attributes most accurately used and give significant influence. Classification is done using the Logistic Regression algorithm. Data is shared using a split method with 90% training data and 10% testing data, with the aim of optimizing the training process. The performance result consists of an accuracy of 88.53%, a classification error value of 11.4%, can be categorized as low, showing only a few errors produced by the algorithm model, a kappa value of 0.68 close to 1, so it is categorized well, a low RMSE rating of 0.3 indicates a model accurate, and a high AUC percentage of 93.4% indicates the correct algority used in this dataset, because it produces a good performance value.

Abstract

Star Silver Jewelry Shop is a business entity that operates in the field of selling silver jewelry. It was discovered that this shop still uses handwritten manual transaction proof. When a business is run manually, of course many problems arise, one of which is difficulty in managing transaction data such as proof of sales, item data, item codes and large amounts of sales results. So this research is here to provide a solution. The type of research used is research and development (R&D). This web-based application was created using the CodeIgniter 3 framework, Tailwind CSS and MYSQL database, with the PHP programming language and a little JavaScript. This website contains a login page as an initial display, where users are required to log in to validate whether the operator behind it is an officer or not, then they will be forwarded to a dashboard page with several customized menus.

Abstract

The map archiving system in the Jambi Province DPAD is currently facing quite serious challenges because it still relies on manual recording methods. This reliance on manual recording has caused the process of searching for map archive data to be slow and inefficient. Employees have to spend quite a long time searching for and managing the necessary information, resulting in disruptions in productivity and a high potential for data errors. To address this issue, we designed a solution that we believe can provide significant improvements in the management of map archive data. This project is in the form of designing a Website-Based Map Archive Data Information System which will replace the existing manual method. By using web-based technology, this system is specifically designed to increase efficiency and accuracy in managing map archives. It is hoped that with the implementation of this system, the data search and management process will become faster, easier and more structured, thereby helping to increase productivity and reduce the risk of errors in information management.
