Abstract

The detection of a vehicle in video is a activity that is important to help the security forces keep an eye on the traffic flow. However, it is hard to security forces to keep watching the video (CCTV) of traffic flow in all day long. Artificial intelligence can be use to help the security to monitoring and analyze the traffic of vehicles, such as to know the level of vehicle traffic density at a certain time period or find out detailed information about the vehicle that want to observe. In this study, Principle Component Analysis (PCA) method used to doing background substraction process to detect vehicles in a real time. To improve the results of PCA method, morphological operation is implemented. The experiment result shown that PCA method is well used to detect the vehicle in a real time with accuracy at 95%.

Abstrak Pendeteksian kendaraan menggunakan video merupakan kegiatan yang penting untuk membantu pihak keamanan untuk mengawasi arus lalu lintas. Akan tetapi, sangat sulit bagi pihak keamanan untuk terus mengawasi video arus lalu lintas sepanjang hari melalui CCTV. Oleh karena itu kecerdasan buatan dapat digunakan untuk membantu pihak keamanan dalam memantau dan menganalisis lalu lintas kendaraan, seperti untuk mengetahui tingkat kepadatan lalu lintas kendaraan pada periode waktu tertentu atau mengetahui informasi terperinci tentang kendaraan yang ingin diamati. Dalam penelitian ini, metode Principle Component Analysis (PCA) digunakan untuk melakukan proses substraksi latar belakang untuk mendeteksi kendaraan secara real time. Untuk meningkatkan hasil metode PCA, operasi morfologi diimplementasikan. Hasil percobaan menunjukkan bahwa metode PCA baik digunakan untuk mendeteksi kendaraan secara real time dengan tingkat akurasi 95%.

Abstract

Salah satu organ penting dalam tubuh manusia adalah jantung, Jika jantung mengalami gangguan maka dapat menyebabkan penyakit jantung. Untuk mendeteksi adanya penyakit jantung biasanya dilakukan dengan berkonsultasi dengan tenaga medis. Akan tetapi dengan semakin banyaknya pasien di rumah sakit akan dapat memperlambat pendeteksian penyakit jantung. Oleh karena itu dibutuhkan suatu sistem yang dapat membantu tenaga medis dalam mempercepat pendeteksian penyakit jantung. Dalam penelitian ini diusulkan untuk menggunakan pendekatan machine learning seperti metode K Nearest Neighbor (KNN) dalam mendeteksi penyakit jantung. Data yang digunakan sebanyak 1025 pasien dengan 13 fitur seperti umur, jenis kelamin, rasa sakit di dada, tekanan darah saat sedang istirahat, kadar kolesterol, gula darah, hasil elektrografik saat sedang istirahat, detak jantung maksimal, jika mengalami nyeri dada saat latihan, depresi yang diinduksi oleh latihan relatif, kemiringan puncak ST segmen, jumlah pembuluh darah yang berwarna setelah diwarnai flourosopy dan tipe kerusakan pembuluh darah. Pada penelitian ini dilakukan tiga skema pembagian data latih dan data uji dengan rasio 60:40, 70:30 dan 80:20. Berdasarkan hasil pengujian diperoleh bahwa tingkat akurasi, presisi dan recall tertinggi terjadi Ketika rasio data latih dan data uji 70:30 yaitu sebesar 97,0779% untuk akurasi, 97,9166% untuk presisi dan 95,9183% untuk recall.One of the important organs in humans is the heart. If the heart is disturbed, it can cause heart disease. To detect the presence of heart disease is usually done in consultation with doctor. However, with the increasing number of patients in the hospital, it will be able to slow down the detection of heart disease. Therefore, we need a system that can assist doctors in accelerating the detection of heart disease. In this study, we propose to use a machine learning approach i.e., K Nearest Neighbor (KNN) method in detecting heart disease. The data used were 1025 patients with 13 features i.e., age, gender, chest pain, blood pressure, cholesterol, blood sugar, electrographic results, maximum heart rate, if you experience chest pain during exercise, depression which exercise-induced relative, peak slope, number of blood vessels after fluoroscopy and type of vessel damage. In this study, we have three schemes in divide training data and test data with ratios of 60:40, 70:30 and 80:20. Based on the test results, it was found that the highest levels of accuracy, precision and recall occurred when the ratio of training data and test data was 70:30, which was 97.0779% for accuracy, 97,9166 for precision and 95,9183% for recall.

Abstract

Direktorat Jenderal Anggaran (DJA) is an organizational unit within the Ministry of Finance with the task of providing an information system related to budgeting performance. The dynamics of policy changes that have occurred recently have resulted in changes to the information system that has been developed by DJA. DJA has socialized the existing business processes and systems, but many users still ask questions through the DJA customer service channel which can only respond during business hours. This research will propose a solution for optimizing these services by creating a chatbot based on Natural Language Processing using the Rasa Open Source framework, which will be installed on one of the DJA's core systems, namely the Performance Monitoring and Evaluation Application. The chatbot will spontaneously answer user questions related to the application. The data used in this study are Frequently Asked Questions (FAQ) data, knowledge base Kemenkeupedia, Focus Group Discussions (FGD) and Performance Monev Application data taken via the API (Application Programming Interface). The results of this study are Chatbot FAQs embedded in the performance monitoring and evaluation application. The intent prediction test produces an accuracy value of 0.986, a weighted precision value of 0.973, a recall of 0.986, and an f1-score of 0.980 then the response prediction produces an accuracy value of 0.980, a weighted precision value of 0.986, a recall of 0.980, and an f1-score of 0.980. This shows that the chatbot is able to identify intent very well and respond appropriately to the user.

Abstract

Pengabdian masyarakat dilakukan di RW 22 Perum Metland Cileungsi Sektor VII untuk meningkatkan pemahaman matematika siswa dan kemampuan penggunaan Google Meet pada ibu-ibu. Kegiatan ini diilustrasikan oleh rendahnya pemahaman konsep matematika dan kurangnya penguasaan teknologi oleh ibu-ibu. Dalam empat bulan, kegiatan melibatkan30 siswa dan 20 ibu-ibu, menggunakan metode pengajaran matematika kontekstual dan media visual, serta pelatihan penggunaan Google Meet dengan pendekatan hands-on. Evaluasi melibatkan kuesioner, wawancara, dan tes hasil belajar. Hasil menunjukkan peningkatan pemahaman matematika, kecakapan penggunaan Google Meet, serta penerapan teknologi dalam pembelajaran matematika. Pelatihan dan modul pembelajaran matematika telah berhasilmeningkatkan daya saing siswa dan ibu-ibu. Pengabdian ini membuktikan pentingnya penerapan iptek dalam pendidikan dan memberikan rekomendasi kebijakan untuk pengembangan sumber belajar masyarakat. Dengan ini, kemampuan masyarakat dalam menghadapi era digital dapat ditingkatkan.
