Abstract

Currently, the use of digital video in the field of computer science is increasingly widespread, such as the process of tracking objects, the calculation of the number of vehicles, the classification of vehicle types, vehicle speed estimation and so forth. The process of taking digital video is often influenced by bad weather, such rain. Rain in digital video is considered noise because it is able to block objects being observed. Therefore, a rainfall noise reduction process is required in the video. In this study, the reduction of rain noise in digital video is using Daubechies wavelet transformation through several processes, namely: wavelet decomposition, fusion process, thresholding process and reconstruction process. The threshold value used in the thresholding process is VishuShrink, BayesShrink, and NormalShrink. The result of the implementation and noise reduction test show that Daubechies db2 level 3 filter gives the result with the biggest PSNR value. As for the type of threshold that provides optimal results is VishuShrink.

Abstract

The development of digital image processing technology has many benefits, one of which is the identification of an object, such as the identification of the image of the hijaiyah letter. Hijaiyah letters are the letters of the arabic alphabet as the original language of the Qur'an. In essence, humans have the ability to recognize and distinguish hijaiyah letter patterns from one another, but this is not the case with computers, using digital images and machine learning, in this study an identification concept was built by recognizing the image of hijaiyah letters using one of the machine learning methods. namely the extreme learning machine (ELM) method. Extreme learning machine (ELM) is a feedforward neural network with one hidden layer or better known as single hidden layer feedforward neural networks (SLFNs). Therefore, the purpose of this study is that the computer can identify objects as well as human capabilities and see how accurate the results obtained in the ELM method are. The digital image identification process using the extreme learning machine (ELM) method is carried out in two stages, namely training and testing, where previously the preprocessing process was carried out first by changing the color of the RGB image to HSV and processing the color v, then segmentation was carried out with the aim of separating the objects (foreground) with the background, then to make it easier to recognize the pattern, a morphological process is carried out. From the simulation carried out on the test data, the results obtained an average accuracy of 90% with an error of 10%.

Abstract

This study systematically evaluates the robustness of Multi-Layer Perceptrons (MLPs) And Logistic Regression (LR) models against data pertubations using the MNIST handwritten digit dataset. While MLPs and LR are foundational in machine learning, their comparative resilience to diverse pertubations-noise, geometric distortions, and adversarial attacks-remains underexplored,despite implications for real-world applications with imperfect data., whe test three pertubations categories : Gaussian noise (σ=0.1 to 1.0), salt and pepper noise (p=0.1 to 0.5), rotational distorsions (5° to 30°), and adversial attacks (FGSM with ϵ=0.005 to0.30). both models were trained on 60.000 MNIST samples and tested on 10.000 pertubed images. Results demonstrate that MLPs exhibit superior robustness under moderate noise and rotations, achieving baseline accuracies of 97.07% (vs. LR’s 92.63%). For Gaussian noise (σ=0.5), MLP retained 35.35% accuracy compared to LR’s 23.91% . however, adversarial attacks (FGSM, ϵ= 0.30) reduced MLP accuracy to 0.20%, revealing critical vulnerabilities. Statistical analysis (paired t-test, p < 0.05) confirmed significant performance differences across pertubations levels. Alinear regressions (R^2 = 0.98) further quantified MLP’s predictable accuracy decline with Gaussian noise intensity. These findings underscore MLP’s suitability for noise-prone environments but highlight urgent needs for adversarial defense mechanisms. Practitioners are advised to prioritize MLPs for tasks with moderate distortions, while future work should integrate robustness enhancements like adversarial training.

Abstract

Perkembangan teknologi digital, terutama media sosial seperti TikTok, telah membawa dampak signifikan terhadap perilaku dan interaksi sosial, khususnya di kalangan remaja. TikTok, sebagai platform yang populer di kalangan siswa, menawarkan berbagai konten hiburan dan kreatif, namun juga berpotensi memengaruhi etika sopan santun penggunanya. Fenomena ini terlihat pada siswa kelas VIII A di SMPN 18 Singkawang, di mana intensitas penggunaan TikTok yang tinggi dikhawatirkan berdampak negatif terhadap sikap dan perilaku mereka. Penelitian ini bertujuan untuk mengetahui apakah terdapat pengaruh penggunaan media sosial TikTok terhadap etika sopan santun siswa kelas VIII A di SMPN 18 Singkawang. Penelitian ini menggunakan pendekatan kuantitatif dengan metode korelasional. Populasi penelitian berjumlah 32 siswa, dan pengumpulan data dilakukan dengan menggunakan angket tertutup yang disusun berdasarkan indikator frekuensi penggunaan TikTok dan perilaku etika sopan santun. Hasil analisis regresi sederhana menunjukkan bahwa terdapat pengaruh negatif yang signifikan antara penggunaan media sosial TikTok terhadap etika sopan santun siswa. Hal ini ditunjukkan dengan nilai koefisien regresi sebesar -0,471 dan nilai signifikansi sebesar 0,010 (p < 0,05). Nilai koefisien determinasi (R Square) sebesar 0,203 menunjukkan bahwa 20,3% variasi dalam etika sopan santun siswa dapat dijelaskan oleh variabel penggunaan TikTok, sementara 79,7% sisanya dipengaruhi oleh faktor lain di luar penelitian ini. Implikasi dari temuan ini adalah perlunya pengawasan dan pembinaan karakter oleh guru dan orang tua dalam penggunaan media sosial di kalangan siswa, khususnya TikTok, agar tidak berdampak negatif terhadap sikap dan perilaku sopan santun mereka. Selain itu, sekolah diharapkan dapat mengintegrasikan nilai-nilai etika dalam kegiatan pembelajaran maupun bimbingan konseling.

Abstract

In this increasingly modern era, there are still women who decide to postpone marriage in order to pursue a career, continue their education, or become the backbone of the family and have not yet found the right partner. In this case, the family has an important role in providing guidance to women who decide to postpone marriage, namely in the form of advice and motivation about family life. In this case, family guidance is one strategy that can be used to deal with women who decide to postpone marriage in Pragaan Laok Village. The problems raised in this research are 1) What are the factors that cause middle-aged women to decide to postpone marriage in Dunglaok Hamlet, Pragaan Laok Village, Pragaan District, Sumenep Regency and 2) What is the family guidance model in an effort to handle middle-aged women who decide to postpone marriage in Dunglaok Hamlet, Pragaan Laok Village, Pragaan District, Sumenep. The approach in this research uses a qualitative approach with a case study type. The method used is observation and interviews. The informants in this study were 3 people who were family members and 4 women who decided to postpone their marriage. The validity of the data in this research is triangulation, namely triangulation of sources and techniques. The results of this research are: First, the factors that cause middle-aged women to decide to postpone marriage are wanting to be the backbone of the family, focusing on continuing their education at a higher level, focusing on a career so they can be independent and make their parents happy. And the second is a model of family guidance in an effort to deal with middle-aged women who decide to postpone marriage, namely providing advice on how to be a good wife and how to build a Sakinah Mawaddah Warahmah family and providing motivation that marriage is a complement to religion and morals.
