ing, and a combination of both in a movie recommendation system. The method used in this study involves retrieving movie details from the TMDB API and ratings from the MovieLens 32M Dataset (2010-2023). Each model's performance is evaluated using evaluation metrics such as RMSE and MAE. The results of this study indicate that Neural Collaborative Filtering achieves the best prediction performance (RMSE = 0.785423, MAE = 0.581262), followed by the hybrid model (RMSE = 0.800863, MAE = 0.660872), while Content-Based Filtering produces low performance and limits the capabilities of the hybrid model. In conclusion, these findings highlight the superiority of latent feature-based models such as NCF that learn directly from user interaction patterns over content-based approaches in the context of modern recommendation systems.

Abstrak: Sistem rekomendasi menjadi semakin penting seiring berkembangnya platform streaming. Tujuan dari penelitian ini adalah membandingkan kinerja Content-Based Filtering, Neural Collaborative Filtering dan kombinasi keduanya dalam sistem rekomendasi film. Metode yang digunakan dalam penelitian ini melibatkan pengambilan detail film dari TMDB API dan rating dari dataset MovieLens 32M Dataset (2010-2023). Setiap peforma model dievaluasi dengan menggunakan metrik evaluasi seperti RMSE dan MAE. Hasil dari penelitian ini menunjukkan bahwa Neural Collaborative Filtering mencapai kinerja prediksi terbaik (RMSE = 0.785423, MAE = 0.581262), diikuti oleh model hybrid (RMSE = 0.800863, MAE = 0.660872), sementara Content-Based Filtering menghasilkankan peforma yang rendah dan membatasi kemampuan model hybrid. Kesimpulannya, penelitian ini menyoroti superiotas model berbasis latent feature seperti NCF yang belajar langsung dari pola interaksi pengguna dibandingkan pendekatan berbasis konten dalam konteks sistem rekomendasi modern.

so that there are several obstacles such as not being able to open the system because the system is hacked by irresponsible parties, the computer network used is often disrupted so that hampers the operational process, and the level of computer security is still relatively weak. This study aims to measure the likelihood of threats and risk impacts on the teaching and learning activity monitoring system and to provide recommendations for risk control of security problems that could become a threat that causes losses to universities. The framework used as a tool to measure the level of threat and risk impact is to use the NIST Special Publication 800-30r-1 framework. The framework of the NIST Special Publication 800-30r-1 has nine phases in carrying out risk assessments, namely introduction of system characteristics, recognition of threats, recognition of vulnerabilities, analysis of handling systems, determining likelihood, determining impact, risk determination, recommending control and determination of results. There are six risk assessment systems for monitoring learning activities at private universities, two of which are high so they are classified as very dangerous and the rest are moderate. The results of this study are used as a reference in making risk control standard documents as a form of improving the quality of a private university.

. Along with the increasingprogress of computer technology, the role of computer technology has also increased for the benefit of humans. One of them is the field of human and computer interaction ( IMK) or also called Human Computer Interaction ( HCI) . Although computer technology equipment is accurate and reliable, but the interaction model that is carried out is not natural as humans interact with each other, the use of such equipment to operate it requires direct contact between user and the computer. For people who dissabilities who do not have hands, it will be difficult to do so. Computer vision based interaction techniques are candidates for natural interaction techniques. The human head can also be used to replace the function of a mouse that can be used to move the cursor up and down left or right for and to click on the mouse using the blik an eye. Detection using head movements has been widely applied including in the fields of entertainment, education, and security. The camera is a tool used to make head recognition. The camera is used as a sensor to detect head movements. Head motion detection is implemented by using opency phython.

Abstrak: Difabel atau kata yang memiliki definisi “Different Abled People†ini adalah sebutan bagi orang cacat. Salah satu contoh kaum difabel adalah orang yang tidak mempunyai tangan, sehingga untuk menulispun harus menggunakan kaki. Seiring meningkatnya kemajuan teknologi komputer, peranan teknologi komputer juga semakin meningkat yang digunakan untuk kepentingan manusia. salah satunya adalah bidang interaksi manusia dan komputer (IMK), atau sering disebut Human Computer Interaction (HCI). Keyboard, mouse, dan joystick merupakan salah satu perangkat keras yang sering digunakan untuk interaksi antara manusia dan komputer yang bersifat mekanis. Meskipun peralatan-peralatan tersebut akurat dan handal (reliable), tetapi model interaksi yang dilakukan tidak bersifat alami sebagaimana manusia berinteraksi dengan sesamanya, penggunaan peralatan-peralatan tersebut untuk mengoperasikannya membutuhkan adanya kontak langsung antara user dengan komputer. Untuk kaum difabel yang tidak mempunyai tangan, akan susah melakukan hal tersebut. Teknik interaksi berbasis visi komputer menjadi kandidat teknik interaksi yang bersifat alami. kepala manusia bisa juga digunakan untuk menggantikan fungsi mouse yang bisa digunakan untuk menggerakan cursor keatas kebawah kekiri maupun kekanan dan untuk melakukan klik pada mouse menggunakan kedipan mata. Pendeteksian menggunakan gerakan kepala telah diaplikasikan secara luas diantaranya pada bidang hiburan, pendidikan serta keamanan. Kamera (webcam) merupakan alat yang digunakan untuk melakukan pengenalan kepala. Kamera ini digunakan sebagai sensor untuk mendeteksi pergerakan kepala. Pendeteksian gerakan kepala diimplementasikan dengan menggunakan opencv python.
Abstract:This research examines the application of the Brain-Based Learning (BBL) model to reduce math anxiety in teaching fractions at the elementary school level. This study used a quantitative approach with a pretest–posttest…
t quasi-experimental control group design involving two fifth-grade classes: one experimental class that received fraction instruction through BBL and one control class that was taught using conventional methods, with 40 students in each group. Mathematics anxiety related to fractions was measured using a modified mathematics anxiety scale for elementary school students, while fraction achievement was evaluated through a valid written test. The results showed that both groups had relatively equivalent initial abilities, supported by normal and homogeneous pretest data and no significant differences in pretest scores. After the intervention, the experimental class showed consistently lower levels of anxiety related to fractions in all dimensions (tests/assessments, classroom learning situations, fraction tasks, and fraction avoidance) and significantly higher post-test scores than the control class, with an average difference of about seven points. The findings show that BBL, which aligns the learning process with the way the brain naturally learns by fostering positive emotions, multisensory experiences, and meaningful social interaction, is effective in improving students' understanding of fractions while simultaneously reducing their math anxiety. This study offers a unique perspective by conducting an experimental trial of BBL as a targeted intervention for math anxiety related to fractions in Indonesian elementary schools and highlighting its potential as a neuroeducation-based pedagogical strategy to foster numeracy and emotional well-being in math learning.

exemptions, deductions, tax incentives, non-taxable income, deferring tax liabilities, and, regrettably, engaging in unethical practices such as bribery and forgery. This study seeks to unravel the intricate relationships between profitability, solvency, capital intensity, and company size regarding tax avoidance within the manufacturing sector, specifically targeting food and beverage firms listed on the Indonesia Stock Exchange from 2017 to 2022. Employing the Cash Effective Tax Rate (CETR) as a proxy for tax avoidance, we meticulously selected a sample of 70 companies through purposive sampling based on rigorous criteria. Our analysis, conducted via multiple linear regression using SPSS 25, reveals compelling insights: profitability, solvency, and capital intensity significantly bolster tax avoidance strategies, while larger company size appears to dampen these efforts. Collectively, these factors create a multifaceted influence on tax avoidance behaviors, highlighting the intricate dynamics at play within the corporate landscape.
