Abstract

Nowadays, handwriting recognition has been widely used for analyzing signature, reading address as well aschanging text to hypertext. Common steps in handwriting recognition system consist of pre-processing,segmentation, feature extraction, classification and post-processing. This research describes segmentationmethods for handwriting character which acquired using online device. Characters used in this research are 19latin alphabets. In the first step, pre-processing is taken place by removing noise manually. The next step iscalculating the speed of writing. The acquired speed value is further used to calculate acceleration by applyinglow-passfilter. As shown in the figure, it is found that there are many peak change has been identified so thatlow-pass filter is also used to reduce the number of segment. Too many segments may increase the difficulties ofthe next process. This research employs 4 segmentation methods, such as Positive Negative Acceleration,Positive Positive Acceleration, Negative Positive Acceleration and Minimum Speed. From the experiments, it isidentified that by applying minimum speed, character segmentation can be perform quite wellKeyword(s): Segmentation, Character, Speed, Acceleration, Low-pass Filter.Subject Description: I.4 Image Processing and Computer Vision | I.4.6 Segmentation | Edge and featuredetection

Abstract

Academic burnout telah menjadi masalah signifikan di kalangan mahasiswa, berdampak negatif pada kesehatan mental dan kinerja akademik. Penelitian ini bertujuan untuk melakukan analisis komparatif terhadap kinerja algoritma Support Vector Machine (SVM) dan Random Forest (RF) dalam memprediksi academic burnout pada mahasiswa di salah satu universitas di DKI Jakarta. Metode penelitian kuantitatif ini menggunakan data primer dari kuesioner Burnout Assessment Tool – Student Version (BAT-S) yang mencakup faktor pribadi, akademik, dan psikologis, serta data sekunder akademik mahasiswa. Data mentah kemudian melalui tahap persiapan yang meliputi pembersihan, penanganan outlier dengan teknik capping, standardisasi, dan penyeimbangan kelas menggunakan BorderlineSMOTE untuk mengatasi distribusi data yang tidak seimbang. Hasil pemodelan menunjukkan performa prediktif yang sangat tinggi untuk kedua algoritma setelah optimasi hyperparameter, dengan SVM mencapai akurasi 98,75% dan RF sebesar 97,50% pada data uji. Meskipun RF menunjukkan keunggulan pada metrik berbasis peringkat seperti ROC-AUC, SVM direkomendasikan sebagai model akhir karena memiliki profil risiko kesalahan yang lebih dapat diterima secara klinis, yakni tidak menghasilkan false negative yang berisiko tinggi. Penelitian ini membuktikan bahwa ML dapat menjadi alat efektif untuk deteksi dini risiko burnout, namun penelitian selanjutnya disarankan untuk mengeksplorasi algoritma yang lebih kompleks seperti gradient boosting dan melakukan analisis kepentingan fitur untuk pemahaman yang lebih mendalam.

Abstract

Berbagai lembaga pemerintah di Indonesia memodernisasi dokumen persuratan secara digital. Pada sistem pencarian yang ada saat ini, pengarsipan dengan melakukan pengunggahan dokumen hasil pindaian surat, pengklasifikasian surat dan penamaan file surat/pembuatan anotasi masih dilakukan secara manual oleh operator, pencarian masih berdasar nama file/anotasi surat belum berdasar isi konten sehingga sulit menemukan surat sesuai konten teks yang diinginkan. Hasil pencarian juga tidak dapat langsung memperlihatkan informasi spesifik tentang kriteria klasifikasi dari dokumen surat yang diketemukan sehingga membutuhkan penelusuran lebih lama untuk betul-betul menemukan dokumen yang diinginkan. Tujuan penelitian ini adalah mengembangkan sistem pencarian surat berbasis konten terklasifikasi dengan ontologi guna meningkatkan kualitas hasil pencarian surat digital secara lebih efisien (spesifik, akurat dan cepat). Metode pengembangan sistem menggunakan model Agile Scrum. Mencakup pre-game (mengumpulkan user stories, product backlog, sprint backlog), game (pengembangan (5 sprint)), post-game (implementasi, penerimaan pengguna dan dokumentasi). Hasil uji coba sistem terhadap dokumen surat Biro Umum Kemdikbud menunjukkan bahwa dalam pengarsipan surat, sistem ini berhasil mengklasifikasikan surat (jenis, asal dan subjek surat) menurut prosedur persuratan yang valid, secara otomatis dengan bantuan kecerdasan artifisial, dan dalam proses pencarian surat, sistem ini berhasil menemukan dokumen surat dengan berdasarkan nama file, konten, kriteria klasifikasi dan menampilkan informasi ontologis rinci yang ditemukan. Kedepannya, sistem ini juga dapat dikembangkan untuk digunakan oleh institusi lain dengan mengubah klasifikasi sesuai dengan prosedur persuratan yang berlaku.   Abstract Various government institutions in Indonesia have modernized digital correspondence documents. Archiving is done by uploading scanned letters, classifying letters, and naming mail files/annotations by the operator, searches are not based on content, so it is difficult to find letters that have the desired content, search results also cannot immediately show information of classification criteria of the found mailing documents, so it requires a longer search actually to find the desired document. Research objectives develop a classified content-based mail search system with ontology to improve the quality of electronic correspondence search results more efficiently. The system development method uses the Agile Scrum model. Includes pre-game (collecting user stories, product backlog, sprint backlog), game (development (5 sprints)), and post-game (implementation, user acceptance and documentation).The results of the system trial on the Ministry of Education and Culture's General Bureau of Letter Documents show that during the archiving of the letter, this system succeeded in classifying the letter (type, origin and subject of the letter) according to valid comprehension procedures, automatically with the assistance of artificial intelligence, and in the process of searching for letters, the system This managed to find a letter document based on the file name, content, classification criteria and display detailed ontological information found. In the future, this system can also be developed for use by other institutions by changing the classification in accordance with the comprehension procedures.

Abstract

The Covid-19 pandemic in Indonesia, which began in 2019, has had an impact on all levels of society. With this pandemic occurring, the Indonesian government made several policies with the aim of stopping the spread of the Covid-19 virus. One form of policy that is carried out is by imposing a system of Imposing Restrictions on Community Activities (PPKM), to prevent the spread of the virus through physical contact. The existence of this PPKM is one of the drivers of digitization in almost all sectors. This transformation in the digital world must be facilitated with qualified infrastructure. One example of important infrastructure needed to support digital transformation is a server and to be specific is a database server. To improve and optimize the performance of the server, system development is carried out using docker swarm on a mariadb database clustered with galera clusters on more than one host (multi host) that can be done by installing ubuntu and docker, swarm initialization, create overlay network, pull galera image, create cluster service, Prometheus and grafana installation and configuration, test integeration on database, and monitoring server. All cpu usage percentage from monitoring results show the percentage not reach 100% which means there are no overload and overworked.

Abstract

Corona Virus Disease 2019 (Covid-19) has stopped all aspects of human life, including the world of education. The Ministry of Education of the Republic of Indonesia has stopped face-to-face teaching and learning activities in schools, replacing them with online methods. Work from Home (WFH) is an adaptation of activities as applied online methods to anticipate learning activities during the Covid-19 Pandemic. Learning based on digital transformation technology utilizes network technology entirely online. The application of e-learning technology in the teaching and learning process is a choice for various educational institutions. The use of technology can maximize students 'learning time efficiency and increase students' concentration. Learning with the Virtual Reality (VR) method directs students to discoveries, motivates, encourages, and provides more curiosity for students in learning. Besides VR, Augmented Reality (AR) is a learning method for students to interact with virtual objects and real objects. The author proposes e-learning based learning in Natural Sciences (IPA) subjects in grade 3 in Elementary Schools. The research proposal develops lessons using a virtual approach from real events and provides phenomena of natural occurrences. Science lessons in Elementary Schools increase the curiosity of students scientifically. This method will help students develop the ability to ask questions and find answers to natural phenomena. The research stages carried out in application development are analysis, design, implementation, and application testing. The test results by adding e-learning to traditional learning methods impacted students' understanding of the material with an increased level of understanding by 24%.
