Abstract

In the fast-growing E-Sports industry, athlete performance is the key to achieving success and winning. Therefore, analyzing the factors that contribute to the performance of E-Sports athletes is essential in order to optimize their performance in competition. This study aims to analyze the relationship between age, number of training hours, and experience playing in competition with rank, kill death ratio (KDA), and the number of wins of E-Sports athletes using the OSEMN approach (Obtain, Scrub, Explore, Model, Interpret, and Communicate). The data was obtained from 300 professional or non-professional E- Sports athletes, over the past three years who were involved in various competitions. Independent variables included age, number of training hours, and experience playing in competitions, while the dependent variables included rank, KDA, and number of wins. Data was collected, processed and explored and then analyzed using multiple linear regression methods. This study succeeded in applying the regression analysis method using the OSEMN framework, identifying relevant variables, and developing effective data collection and processing methods. This model has the potential to provide accurate predictions of E- Sport athlete performance data. However, it is still important to consider other factors such as business context, comparison with other models, and cross- validation to confirm the reliability of the prediction results.

Abstract

ADHD (Attention Deficit Hyperactivity Disorder) adalah gangguan perkembangan otak pada anak yang mengakibatkan meningkatnya aktifitas motorik sehingga menyebabkan penderitanya menjadi hiperaktif, impulsif dan inatentif. Kondisi ini sering memperlihatkan tingkah laku yang tidak wajar seperti selalu bergerak tanpa tujuan, selalu gelisah, atau tidak bisa duduk dengan tenang. Gangguan ADHD terbagi menjadi tiga jenis yaitu Hiperaktif, Inatentif dan Impulsif. Salah satu cara untuk mendiagnosa jenis ADHD yang diderita oleh anak adalah dengan konseling. Tujuan dari penelitian ini adalah membangun sebuah sistem pakar yang dapat membantu memberikan kesimpulan tentang jenis penyakit ADHD yang diderita oleh anak serta tingkat keyakinan diagnosisnya. Penelitian ini menggunakan metode Dempster-Shafer untuk melakukan perhitungan terhadap nilai keyakinan suatu diagnosa. Hal ini dilakukan dengan cara membandingkan setiap nilai keyakinan dari 2 gejala awal yang terjadi pada anak untuk selanjutnya dibandingkan lagi dengan nilai keyakinan dari gejala-gejala lainnya. Sehingga mengerucut pada suatu gejala yang mengacu kepada suatu jenis dari ADHD disertai dengan nilai keyakinannya seperti layaknya diagnosa seorang pakar psikologi anak. Dalam penelitian ini dibangun sistem pakar berbasis Android dengan basis pengetahuan dari 3 orang pakar untuk memudahkan orang tua anak dalam mendiagnosa gejala-gelaja yang mungkin diderita oleh anaknya. Hasil pengujian sistem terhadap pakar dengan persentase rata-rata sebesar 93,3% dari 3 orang pakar, menunjukan bahwa sistem pakar yang telah dibuat mampu mendiagnosa jenis perilaku ADHD yang diderita oleh anak-anak disertai dengan nilai tingkat keyakinan diagnosisnya.Abstract ADHD (Attention Deficit Hyperactivity Disorder) is a brain development disorder in children resulting in increased motor activity causing the sufferer to become hyperactive, impulsive and inattentive. This condition often shows unnatural behavior like always moving aimlessly, always restless, or unable to sit quietly. ADHD disorders divided into three types, namely Hyperactive, Inattentive and Impulsif. One way to diagnose the type of ADHD suffered by children is by counseling. The purpose of this study is to build an expert sistem that can help provide conclusions about the kind of ADHD that the children had and the diagnosis level of confidence. This research uses Dempster-Shafer method to perform the calculation of confidence value of diagnosis. This is done by comparing each of the confidence values of the two early symptoms that occur in the child to furthermore compare with the belief value of the other symptoms. Therefore, conical to a symptom that refers to a type of ADHD accompanied by the value of the diagnosis beliefs, just like the diagnosis of a child psychologist. In this study, an Android-based expert system with a knowledge base from three experts is built to facilitate the child's parents in diagnosing symptoms that may be suffered by his son. The experimental test of the system with the mean percentage of 90% from 3 experts, indicates that the expert system that has been made can diagnose the type of ADHD behavior suffered by the children accompanied by the value of the diagnosis confidence level.

Abstract

Unit Pusat Terpadu Perpustakaan merupakan perpustakaan pusat yang ada di Universitas Lambung Mangkurat. Perpustakaan ini mempunyai sistem pencarian buku namun sistem tersebut belum adanya fitur rekomendasi buku sehingga anggota menjadi kesulitan dalam melakukan pencarian buku yang sesuai dengan keinginan anggota. Oleh karena itu, dengan adanya rekomendasi buku atau saran buku yang lain dapat menjadi alternatif untuk membantu anggota dalam melakukan pencarian buku yang sesuai. Dalam penelitian ini menggunakan perbandingan pembobotan kata TF-IDF dan TF-RF dengan weighted tree similarity sebagai pengukur kemiripan diantara beberapa data dengan parameter tree yang sudah ditentukan dan dilakukan perbandingan perhitungan dengan menghitung tf-idf dengan tf-rf menggunakan perhitungan excel mendapatkan nilai yang berbeda antara tf-idf dengan tf-rf, pembobotan tf-idf dapat mengukur kemiripan antara dokumen dan kata kunci buku yang paling mirip dengan buku yang dianggap paling relevan. Sehingga anggota memasukan kata kunci kemudian akan menemukan kemiripan buku dari kata kunci yang dimasukan sebelumnya namun untuk pembobotan tf-rf memberikan kata kunci dari setiap kategori. Hasil perbandingan yang di dapat yaitu 96% untuk tf-idf dan 98% untuk tf-rf. Sistem ini menggunakan bahasa pemrograman python dengan web framework django. AbstractThe Central Integrated Library Unit is the central library at Lambung Mangkurat University. This library has a book search system but the system does not have a book recommendation feature so that members find it difficult to search for books that match the wishes of members. Therefore, the existence of book recommendations or other book suggestions can be an alternative to assist members in searching for suiTabel books. In this study using a comparison of the weighting of the words TF-IDF and TF-RF with weighted tree similarity as a measure of the similarity between several data and a comparison of calculations is carried out by calculating tf-idf with tf-rf using excel calculations to get different values between tf-idf and tf -rf, tf-idf weighting can measure the similarity between documents and keywords of the book that is most similar to the book that is considered the most relevant. So that members enter keywords and then find the similarity of books from the keywords entered previously but for weighting tf-rf provides keywords from each category. The comparison results obtained are 76% for tf-idf and 80% for tf-rf. This system uses the python programming language with the django web framework.

Abstract

Deteksi kendaraan bergerak adalah salah satu elemen penting dalam aplikasi Intelligent Transport System (ITS). Deteksi kendaraan bergerak juga merupakan bagian dari pendeteksian benda bergerak. Metode K-Means berhasil diterapkan pada piksel cluster yang tidak diawasi untuk mendeteksi objek bergerak. Secara umum, K-Means adalah algoritma heuristik yang mempartisi kumpulan data menjadi K cluster dengan meminimalkan jumlah kuadrat jarak di setiap cluster. Dalam makalah ini, algoritma K-Means menerapkan jarak Euclidean, jarak Manhattan, jarak Canberra, jarak Chebyshev dan jarak Braycurtis. Penelitian ini bertujuan untuk membandingkan dan mengevaluasi implementasi jarak tersebut pada algoritma clustering K-Means. Perbandingan dilakukan dengan basis K-Means yang dinilai dengan berbagai parameter evaluasi yaitu MSE, PSNR, SSIM dan PCQI. Hasilnya menunjukkan bahwa jarak Manhattan memberikan nilai MSE = 1.328 , PSNR = 21.14, SSIM = 0.83 dan PCQI = 0.79 terbaik dibandingkan dengan jarak lainnya. Sedangkan untuk waktu pemrosesan data memperlihatkan bahwa jarak Braycurtis memiliki keunggulan lebih yaitu 0.3 detik. AbstractDetection moving vehicles is one of important elements in the applications of Intelligent Transport System (ITS).

Abstract

Cassava or better known as cassava is one of the staples of rice which is popular in Indonesia. Cassava plants can flourish in almost all regions of Indonesia. However, cassava is a plant that is susceptible to plant disease, which attacks the disease resulting in a decrease in the amount of productivity of tubers produced by cassava plants. The application of identifying cassava disease based on leaf image is expected to be useful as a support for cassava farming in easily detecting cassava disease, so that it can be dealt with more quickly. This study uses the Gray Level Co-occurrence Matrix (GLCM) method as an extraction feature and the Probabilistic Neural Network (PNN) method for identification processes. Based on the results of tests on 6 types of cassava leaf images, obtained an accuracy of 83.33%.

Abstract

The current digital literature resources are widely provided by various libraries, especially those associated with higher education institutions. One such example of a digital library is the Lambung Mangkurat University Digital Library (Digilib ULM). Pre-evaluation results indicate that around 50% of the issues are related to the quality of the website, such as its appearance and functionality. Therefore, this research examines the quality of the ULM Digital Library to identify indicators that match user preferences and require improvement. The Webqual 4.0 method and User Experience Questionnaire are uti- lised for this purpose. The research is quantitative with a descriptive approach. Data is collected through a questionnaire, with 100 respondents sampled from the entire population, consisting of ULM students. Webqual 4.0 comprises three dimensions: usability, information quality, and service interaction. Meanwhile, UEQ consists of six aspects: attractiveness, dependability, efficiency, perspicuity, stimulation, and novelty. The research findings from Webqual 4.0 indicate a service interaction score of 2.75, information quality of 2.68, and usability of 2.45. The usability aspect falls into the low category or does not meet user expectations, while the other aspects fall into the moderate category. The UEQ results show an attractiveness score of 1.130, efficiency of 0.648, and novelty of 0.673, all scoring below the average compared to benchmarks, while other aspects score above average. Based on these results, it is evident that the Digilib ULM website does not meet user expectations and can be considered suboptimal, requiring improvement and enhancement.
