Abstract

Neural Networks - Multiscale Autoregressive (NN-MAR) model is a development of neural network. The network is built by using wavelet theories for time series forecasting. There are few research explaining how NN-MAR model can be used for forecasting seasonal time series data. The main aspect for forecasting seasonal time series data is the lag inputs, which should include seasonal lags. The procedure starts from Maximal Overlap Discrete Wavelet Transform (MODWT) decomposition. For non-stationary data, the differencing process is used to get a stationary data. From the decomposition process we get the scale and wavelet coefficients. The lags of these coefficients are used as the inputs in the network. In the hidden layer, the number of hidden neurons is chosen by using the criterion of R2incremental and F-test, so that we get the best NN-MAR model. The aim of this research is to build NN-MAR model for seasonal time series data, such as tourism data. The number of international tourist coming to Soekarno-Hatta airport in Jakarta and to Ngurah Rai airport in Bali are used as the case study.

Abstract

Kontroler PID adalah kontroler yang paling populer abad ini karena kefektifannya luar biasa, implementasinya sederhana dan aplikasinya sangat luas. Namun, dalam prakteknya tuning kontroler PID merupakan suatu persoalan tersendiri yang tidak mudah dan umumnya masih dilakukan secara manual yang memerlukan cukup waktu. Tugas akhir ini membahas teknik tuning kontroler PID menggunakan metode PSO (Particle Swarm Optimization). Hasil simulasi menunjukkan bahwa metode PSO yang digunakan untuk mendapatkan nilai parameter PID  menghasilkan performa sistem yang baik terutama pada saat wmin = 0,25, wmax = 0,75 jumlah populasi sebanyak 50 dan dilakukan sebanyak 50 iterasi didapatkan Kp = 11,2215, Ki = 2,0873 dan Kd = 5,4503 dan ketika dilakukan didapati rise time sebesar 8,4 detik, overshoot sebesar 2%, setling time sebesar 10,72 detik dan error steady state sebesar 20 RPM.

Abstract

Studying from home during the Covid-19 pandemic is more effective if the teacher concerns the student’s interest in learning and learning styles. The study aimed to analyze student’s interest in learning and learning styles and to describe factors influencing interest in learning and learning styles to fifth grade students at SD Negeri 3 Cikembulan during the Covid-19 pandemic. It was qualitative with narrative design. Data collection techniques used observation, interviews, and document studies. The observed aspects about interest in learning were fondness, interest, and student involvement while about learning styles were visual auditory, and kinesthetic. It concludes that student’s interest in learning is sufficient. The dominant student learning style is visual. Factors influencing interest in learning include talent, discipline, curiosity, concentration, learning needs, family, motivation, school, mass media, and society while factors influencing learning style include physical conditions, psychology, fatigue, family, school, and society.

Abstract

The millennial era can be felt as an era full of paradoxes. Millennial families are the construction of new family realities that are not completely in line with traditional Islamic family norms/laws that encourage modernization in Islamic law. This study aims to find out the method of ijtihad in Indonesia in renewing Islamic family law and its scope in the milennial era. The type of research used is descriptive qualitative research using literature research methods in which family law is an object of research. The results of the study show that the ijtihad method used was a method of combining various methods of normative ijtihad of the scholars by considering the demands of modern legislation. Renewal of Islamic family law in the midst of social change, includes: (1) Islamic family law as a social reality in the process of social reform; (2) Transformation of Islamic family law values ​​from living law but not structured into national law; (3) Islamic family law as a living reality and social transactions towards consensus; (4) Modernization and shift in the value of Islamic family law; (5) Law as the reality and process of cultural transplantation; (6) Islamic family law and peace negotiations with globalization of values; (7) Islamic family law becomes part of the positivation of national law.
