Abstract

Hasil klasifikasi kanker payudara yang tidak tepat dan memiliki akurasi rendah berpotensi membahayakan nyawa pasien. Rasio split data training dan testing mempengaruhi akurasi klasifikasi. Pemilihan rasio split data yang tidak tepat dapat menurunkan akurasi model. Penelitian ini bertujuan menemukan komposisi data terbaik untuk hasil klasifikasi kanker payudara yang baik. Metode yang digunakan adalah holdout dan k-fold cross validation. Algoritma klasifikasi yang dibandingkan adalah SVM, Random Forest, dan Naïve Bayes. Hasil penelitian menunjukkan performa akurasi yang berbeda pada ketiga algoritma tergantung pada metode validasi. Skema holdout validation dengan rasio 75%:25% menghasilkan akurasi terbaik untuk SVM, yaitu 98.89%. Algoritma Random Forest mencapai akurasi terbaik pada rasio split data 55%:45%, yaitu 95.85%. Namun, Naïve Bayes memiliki performa akurasi yang lebih baik saat menggunakan k-fold cross validation dengan akurasi 93.85%. Metode holdout dengan rasio 75:25 terbukti menghasilkan akurasi terbaik untuk klasifikasi data kanker payudara menggunakan SVM. Penelitian selanjutnya dapat menggunakan algoritma deep learning dan memperluas penelitian ke jenis kanker lainnya untuk meningkatkan hasil klasifikasi.

Abstract

Memprediksi laju penguapan memiliki manfaat yang luas dalam berbagai aplikasi seperti manajemen sumber daya air, pertanian, dan lingkungan hidup. Namun untuk mendapatkan data yang lengkap dan akurat dalam mempelajari laju penguapan memiliki tantangan tersendiri. Selain itu, rendahnya tingkat linieritas antara data laju penguapan dan faktor meteorologi lainnya di wilayah tropis dapat menyebabkan hasil prediksi yang bervariasi. Tujuan dari penelitian ini adalah memprediksi laju penguapan harian di Stasiun Klimatologi Yogyakarta dengan membandingkan kinerja dua model machine learning (ML) yaitu random forest regression (RFR) dan support vector regression (SVR) menggunakan data pengamatan meteorologi harian. Untuk meningkatkan akurasi prediksi, dilakukan optimasi hyperparameter menggunakan metode gridsearch cross-validation untuk mencari kombinasi hyperparameter terbaik. Hasil optimasi hyperparameter pada data training menunjukkan bahwa model RFR menghasilkan skor RMSE sebesar -0,67 sementara model SVR pada kernel RBF menghasilkan skor RMSE negatif sebesar -0,57. Evaluasi lebih lanjut dilakukan pada data testing dengan menggunakan kombinasi hyperparameter hasil optimasi model RFR menghasilkan nilai R2 sebesar 0,79 dan RMSE sebesar 0,56 sedangkan model SVR menghasilkan koefisien determinasi (R2) sebesar 0,81 dan RMSE sebesar 0,53. Berdasarkan hasil perbandingan kedua model dapat disimpulkan bahwa model SVR memiliki kinerja yang lebih baik dalam memprediksi laju penguapan harian. Penggunaan teknik prediksi dengan model ML untuk memprediksi laju penguapan dapat menjadi solusi untuk mengisi kekosongan data pengamatan meteorologi dan memiliki manfaat yang signifikan dalam bidang pertanian dan hidrologi. Penelitian selanjutnya dapat melibatkan pengembangan sistem informasi pemantauan dan pengelolaan sumber daya air yang lebih efektif dan efisien.

Abstract

The red chili variety "inko hot" is a type of red chili that has a high economic value. Unfortunately, these red chili plants are often infected with anthracnose disease, which results in significant losses for farmers. Anthracnose is one of the major diseases infecting chili plants, potentially resulting in crop failure and losses of up to 80%. The purpose of this study is to develop a classification system to identify anthracnose disease in red chili fruit, using Convolutional Neural Network (CNN) method. In this experiment, 1500 data were used, of which 80% were used as training data and 20% as validation data. The best results of this experiment produced a model with an accuracy of 97% and a loss rate of 6.45%, by applying the Nadam optimization algorithm and going through 50 iterations (epochs). The model showed good performance with a prediction accuracy rate of 83.33%. The development of this classification system has significant potential in providing efficient solutions to recognize diseases in chili plants. Through continuous development, this system can be a valuable tool for farmers to increase crop productivity and reduce the negative impact of disease attacks on red chili peppers and other crops.

Abstract

Pattern recognition, including handwriting recognition, has become increasingly common in everyday life, as is recognizing important files, agreements or contracts that use handwriting. In handwriting recognition, there are two types of methods commonly used, namely online and offline recognition. In online recognition, handwriting patterns are associated with pattern recognition to generate and select distinctive patterns. In handwritten letter patterns, machine learning (deep learning) is used to classify patterns in a data set. One of the popular and accurate deep learning models in image classification is the convolutional neural network (CNN). In this study, CNN will be implemented together with the OpenCV library to detect and recognize handwritten letters in real-time. Data on handwritten alphabet letters were obtained from the handwriting of 20 students with a total of 1,040 images, consisting of 520 uppercase (A-Z) images and 520 lowercase (a-z) images. The data is divided into 90% for training and 10% for testing. Through experimentation, it was found that the best CNN architecture has 5 layers with features (32, 32, 64, 64, 128), uses the Adam optimizer, and conducts training with a batch size of 20 and 100 epochs. The evaluation results show that the training accuracy is between 85, 90% to 89.83% and testing accuracy between 84.00% to 87.00%, with training and testing losses ranging from 0.322 to 0.499. This research produces the best CNN architecture with training and testing accuracy obtained from testing. The developed CNN model can be used as a reference or basis for the development of more complex handwriting pattern recognition models or for pattern recognition in other domains, such as object recognition in computer vision, facial recognition, and other object detection.

Abstract

An increase in sales transaction data every day will cause a very large amount of product sales transaction data to be stored. In most cases, data relating to very large sales transactions are only stored and used for archival purposes, not exploited adequately. In retail marketing, association data mining is used to investigate product purchasing patterns. However, if the company does not know the customer's purchasing patterns, it can have impacts such as inappropriate marketing strategies, decreased customer retention, lost business opportunities, lack of personalization, tough competition, stock/production inefficiencies, loss of customer trust. Knowing consumer purchasing patterns, the company can develop sales strategies and make the right decisions. In this study using Market Basket Analysis using the Apriori Algorithm and FP-Growth to determine consumer buying patterns. The results of this study resulted in two itemset combinations. The first combination is that if the buyer buys yogurt and sausage, the buyer also buys whole milk. The resulting support value is 0.00147 (0.0147%), the confidence value is 0.255814 (25.58%) and the lift value is 1.61986. the second combination, namely if the buyer buys sausage (sausages) and rolls/buns (bread rolls), then also buys whole milk (milk), this combination produces a support value of 0.001136 (0.0113%), a confidence of 0.2125 (21.25%) and a lift of 1.34559 . In addition to the combination of the itemset produced in this study, it also measures computational speed in processing Groceries data for Market Basket Analysis. The computational speed produced by the Apriori Algorithm is 3.1765 seconds, while the FP-Growth algorithm is 0.15892 seconds. The difference in computational speed between the Apriori Algorithm and FP-Growth is 3.0176 seconds.

Abstract

The Kanjuruhan tragedy on October 1, 2022, strongly impacted Indonesian football stadium safety. At the Kanjuruhan Stadium, a Persebaya vs. Arema FC match resulted in the deaths of 135 supporters. Due to the significant number of fatalities, there is ongoing debate regarding the responsible parties for the tragedy. Since there are expected to be 18.45 million active users in Indonesia by 2022, Twitter research helps determine popular attitudes. Support Vector Machine is used in this work to evaluate tweets and identify whether they include positive or negative emotions. The categorization outcomes may influence how the public views those responsible for the tragedy. On October 6, 2022, specific Twitter data on tear gas riots, oppressive government, rivalry between supporters, and violence against authorities were taken into account. The sentiment classes are negative, neutral, and positive. The study attained a 95.55% f1-score, 95.16% accuracy, 97.56% precision, and 95.16% recall.

Abstract

Heart attack is a very serious heart disorder. This disorder occurs when the heart muscle does not get good blood flow. This condition will interfere with the function of the heart in flowing blood flow throughout the body. This study aims to develop a system capable of classifying people with heart disease using the Naïve Bayes method. Naïve Bayes is a method that works based on the probability that a person has a heart disease or not based on their medical record data. This algorithm is used with the aim of calculating the probability of a person suffering from heart disease based on their medical records. This data was obtained from the University of California Irvine Machine Learning website with a total of 303 datasets with 13 attributes. This research was conducted by dividing the data into 75% for training data and 25% for training data. The results of this study indicate that the Naïve Bayes algorithm used gives a fairly high accuracy value of 86.84%.

Abstract

A comparison between conventional teaching methods and modern technology reveals a significant difference in the effectiveness and efficiency of educating moderately mentally handicapped children or D3 C class. The available learning materials lack innovation. Monotonous material design that doesn't support interactivity can reduce the interest and engagement of mentally handicapped children. Therefore, the development of more engaging materials that meet their needs is required. D3 C class students with intellectual disabilities require special attention in the use of educational media, considering the current learning materials tend to be monotonous and lacking innovation. Therefore, Augmented Reality (AR)-based learning media can be a promising solution to enhance the quality of learning about various modes of transportation. Interactive AR-based applications enable the introduction of various modes of transportation in a more engaging and interactive way, involving visual and auditory aspects in learning. In application testing, it was proven that the speed of displaying 3D objects was very fast, taking only 2.3 seconds. This contributes to smooth and effective learning for D3 C class mentally handicapped children. Surveys conducted with teachers who have used this AR application indicate a tendency towards positive responses, with the majority of teachers responding "Agree" or "Strongly Agree" to the 10 statements provided. The use of AR in the MDLC approach offers significant potential for improving the education of D3 C class mentally handicapped children. Positive responses to AR reflect innovation in this learning approach, which focuses on individual development, integrated support, and inclusive education. However, it is important to always emphasize supervision to ensure effective AR use, so that children can benefit from a more engaging and tailored learning experience. Thus, the use of AR in the education of D3 C class mentally handicapped children has significant potential to provide innovative and effective learning in various modes of transportation, thereby helping them in their educational process. This research creates a learning method for studying means of transportation for moderately mentally handicapped children using AR technology, which provides innovation in modern times.

Abstract

Upah gaji adalah kompensasi yang diberikan kepada setiap perusahaan, instansi, organisasi, atau badan usaha untuk karyawan yang telah bekerja selama sebulan. Namun, untuk memberikan kompensasi yang adil kepada seluruh karyawan, perusahaan harus mempertimbangkan faktor-faktor seperti absensi, tingkat pendidikan, dan tanggungan dalam pemberian kompensasi. Kriteria ini biasanya digunakan oleh perusahaan besar. Sebenarnya, pengolahan ini sudah ada sejak lama, tetapi sistem yang telah dibuat masih sederhana dan hanya bisa menangani masalah perhitungan yang sederhana. Perhitungan yang lebih kompleks dapat ditentukan menggunakan logika fuzzy melalui beberapa langkah agar mendapatkan hasil yang akurat. Metode Tsukamoto adalah salah satu metode yang menggunakan logika fuzzy dan menghasilkan nilai tegas. Pengambilan data yang tepat dilakukan untuk menentukan gaji dengan kriteria seperti tingkat pendidikan, absensi bulanan, dan tanggungan. Dengan bantuan penelitian ini, organisasi dapat menggunakan perhitungan yang ditemukan dalam penelitian ini untuk menentukan gaji karyawan dengan cepat, baik, dan tepat, sehingga masalah penentuan gaji dapat diselesaikan dengan baik.
