Abstract

Inflasi merupakan salah satu indikator untuk mengukur perkembangan suatu bangsa. Apabila inflasi tidak terkontrol akan memberikan banyak dampak negative terhadap masyarakat disuatu negara. Ada banyak cara untuk mengendalikan inflasi, salah satunya dengan peramalan. Peramalan adalah suatu aktivitas untuk mengetahui kejadian di masa mendatang berdasarkan data masa lalu. Pada penelitian ini menggunakan metode kecerdasan buatan yakni extreme learning machine (ELM). Kelebihan ELM yaitu cepat dalam proses pembelajaran. Berdasarkan penggujian yang dilakukan metode ELM mendapatkan nilai kesalahan sebesar 0.0202008, lebih kecil dibandingkan dengan metode backpropagation sebesar 1.16035821. Hal tersebut membuktikan bahwa metode ELM sangat cocok digunakan untuk peramalan.AbstractInflation is one indicator to measure the development of a nation. If inflation is not controlled will give many negative impacts to the people in a country. There are many ways to control inflation, one with forecasting. Forecasting is an activity to know future events based on past data. In this research using artificial intelligence method is extreme learning machine (ELM). The advantages of ELM are fast in the learning process. Based on ELM testing gets obtained an error value of 0.0202008, smaller than the backpropagation method of 1.16035821. It proves that ELM method is very suitable for forecasting.

Abstract

Sistem rekomendasi dapat dimanfaatkan sebagai alat bantu untuk pengambilan keputusan. Pada sebuah perusahaan, sistem rekomendasi profesi bisa digunakan untuk menempatkan seorang karyawan pada posisi yang tepat. Pada penelitian ini diusulkan sistem rekomendasi profesi berdasarkan Big Five Personality traits yang meliputi Extraversion, Aggreableness, Conscentiousness, Neuroticm, dan Opennes. Input yang digunakan ialah parameter dimensi Big Five Personality yang dirumuskan oleh John. Metode yang digunakan adalah Fuzzy Inference System (FIS) Tsukamoto. Keakuratan sistem dihitung dengan membandingkan output sistem dengan dengan acuan Top Ranked Personality - Based Work Styles for 22 Job Families yang menghasilkan nilai akurasi sebesar 63%.AbstractRecommendation systems can be used as a tool for decision making. In a company, a professional recommendation system can be used to place an employee in the right position. In this study proposed system of professional recommendation based on Big Five Personality traits which includes Extraversion, Aggreableness, Conscentiousness, Neuroticm, and Opennes. The input used is the Big Five Personality dimension parameter formulated by John. The method used is Fuzzy Inference System (FIS) Tsukamoto. The accuracy of the system is calculated by comparing the output of the system with the reference Top Personality - Based Work Styles for 22 Job Families that produce an accuracy score of 63%.

Abstract

Emosi merupakan kondisi psikofisiologis seseorang dengan faktor internal dan/atau lingkungan. Pengenalan akurat dari emosi wajah melalui sistem pengenalan visi komputer akan kondusif untuk kelancaran kemajuan interaksi manusia-komputer. Selain itu, karena dinamika dan heterogenitas layanan seluler, dibutuhkan sistem pengenalan emosi yang dapat memproses data secara akurat dengan waktu komputasi yang minimal. Kami mengusulkan penggunaan MobileNetV3 dengan penjadwalan learning rate serta penambahan attention module guna mendapatkan model dengan performa akurasi baik namun efisien dalam penggunaan sumber daya, seperti ukuran model, jumlah parameter yang rendah, dan waktu komputasi yang cepat, sehingga cocok diterapkan pada perangkat mobile. Adanya SE (Squeeze and Excitation) dan fungsi h-swish memungkinkan MobileNetV3 mempertahankan akurasi sekaligus mengurangi jumlah parameter secara signifikan. Adapun fitur localization dan sampling grid pada spatial transformer membantu model untuk fokus ke bagian yang diperlukan guna meningkatkan akurasi. Pada penelitian ini dibuktikan bahwa metode yang digunakan memberikan hasil yang baik dengan akurasi validasi sebesar 69.89% pada dataset FER2013 dan 84.10% pada FER2013+ dengan ukuran model sebesar 16.36 MB dan parameter 4,235,112 menunjukkan efisiensi memori dan kecepatan inferensi yang signifikan dibandingkan model lain seperti ResNet50 sehingga dapat dinyatakan model memiliki performa akurasi yang baik dengan efisiensi memori dan komputasi yang cukup baik.

Abstract

Climate change is a significant challenge for both humans and the environment, with its impacts increasingly felt across various regions of the world. The most evident consequence is the alteration of extreme weather patterns, which often lead to destructive and life-threatening natural disasters. Among these, extreme rainfall was the most damaging factor, frequently triggering floods. However, the increasing occurrence of related events outlined the urgent need for developing more accurate rainfall forecasting systems as a strategic measure for disaster risk reduction. This research adopted daily rainfall data from Samarinda City, collected between 2004 and 2012, to conduct prediction using both machine and deep learning methods. The implementation of machine learning methods, such as Support Vector Regression (SVR), enabled the model to learn from historical data and uncover complex patterns, resulting in accurate forecasts and improved adaptability to climate variability. Meanwhile, deep learning models, including Recurrent Neural Networks (RNN) and Long Short-Term Memory (LSTM), enhanced prediction performance by capturing more intricate and abstract data relationships. Performance evaluations conducted using Mean Absolute Error (MAE) and Mean Squared Error (MSE) showed that deep learning outperformed machine learning in accuracy. The LSTM model achieved the best performance, with loss values of 0.0482 and 0.0527 for MSE and MAE, respectively. The advantage of deep learning lies in its ability to build more complex models for handling non-linear problems and to learn data representations at various levels of abstraction, which has led to more accurate results. Furthermore, LSTM surpassed RNN by effectively overcoming the vanishing gradient issue, allowing for more stable and efficient training that led to superior predictive performance.
