Abstract

Sekolah merupakan lembaga pendidikan yang sifatnya formal ataupun informal yang dikelola oleh negara atau swasta dengan tujuan untuk memberikan pengajaran, mengelola, dan mendidik para siswa melalui bimbingan yang diberikan oleh para pendidik. Selain kegiatan pengajaran yang dilakukan di sekolah, terdapat aktivitas lain yang juga dilakukan yaitu pengelolaan sekolah. Salah satu kegiatan pengelolaan yang dilakukan adalah administrasi pembayaran uang sekolah siswa. Pengelolaan sekolah yang baik akan membantu meningkatkan layanan pendidikan yang diberikan kepada siswa, orang tua/wali murid dan stakeholder lainnya. Pada SMK Migas Teknologi Riau Pekanbaru, layanan administrasi pembayaran uang sekolah siswa dirasakan masih kurang optimal. Pelayanan pembayaran uang sekolah yang dilakukan selama ini di sekolah adalah dengan pencatatan pada buku kemudian bendahara akan mengeluarkan kwitansi sebagai bukti pembayaran. Pengelolaan data pembayaran uang sekolah yang dilakukan secara manual menyebabkan munculnya masalah mulai dari pencatatan transaksi, penyusunan laporan keuangan yang sering terlambat, bukti fisik penerimaan yang bisa rusak atau hilang, penumpukan keterlambatan pembayaran siswa karena tidak bisa dimonitor setiap saat dan orang tua/wali murid juga tidak bisa mendapatkan pemberitahuan riwayat pembayaran uang sekolah. Tujuan dari kegiatan pengabdian kepada masyarakat ini adalah membantu sekolah dalam penerapan teknologi pada pengelolaan pembayaran uang sekolah siswa sehingga layanan pendidikan yang baik dapat tercapai. Penerapan teknologi dapat membantu mengurangi kemungkinan beban kerja pegawai, meningkatkan manajemen waktu, dan menghasilkan informasi berkualitas dan up to date. Luaran dari pengabdian ini adalah menghasilkan sebuah sistem informasi pembayaran uang sekolah yang memberikan manfaat pada peningkatan waktu layanan, penghematan waktu kerja, kemudahan akses informasi dan keakuratan informasi yang tersedia.

Abstract

The use of indoor and outdoor lighting systems that are still passive makes the use of electrical energy less efficient and classified as wasteful. From the problems that occur in the system that is running, the researchers need to develop a more dynamic system by utilizing the Tsukamoto FLC method and Arduino using voice control to adjust the intensity of the light in the room. After implementing as well as testing the system that has been made, namely the Prototype of Light Intensity Regulator in the Work Room With Voice Control and Fuzzy Logic Control using NodeMCU ESP8266, it is concluded that each component can function according to its function which can be controlled and monitored from the application, implements fuzzy logic control on nodemcu with time and activity input variables obtained from the android application while the room light intensity variable is obtained from the light sensor or LDR. The results of the fuzzy process will adjust the light which is controlled by nodemcu. With the fuzzy logic control in this system, it can adjust the light to the room conditions, making it much more efficient.

Abstract

Machine learning has become an exciting topic in psychology-related research, one of which is counseling psychological readiness for entrepreneurship. An intelligent application developed using a machine learning model to assist the counseling process in measuring a person's psychological readiness for entrepreneurship. This application was generated using the Entrepreneurship Psychological Readiness (EPR) instrument. In this study, to get the most suitable machine learning model, a comparison of 2 (two) machine learning models, namely, Naïve Bayesian (NB) and k-Nearest Neighbor (k-NN), involving 1095 training data. There are 4 (four) prediction classes recommended from the results of counseling: categories not ready for entrepreneurship, given training, guided, and prepared for entrepreneurship. The EPR instrument consists of 33 question items to measure 8 (eight) parameters used as inputs for the prediction process. The data has been randomized, and the experiment has been repeated 5 (five) times to check the consistency of performance of all techniques. 80% of the data was used as training data, and the other 20% was used as testing data. The results of the five (5) trials show that the Naïve Bayesian model provides the most consistent results in predicting a person's psychological readiness for entrepreneurship, with 89.58% accuracy, in testing. Therefore, the Naïve Bayesian model is recommended to be used in psychological counseling to predict a person's readiness for entrepreneurship

Abstract

The rapid growth of harmful web content has intensified the demand for intelligent systems capable of accurately classifying cyber threats based on URL patterns. This study evaluates two widely used supervised learning algorithms, Random Forest and Naïve Bayes, for probabilistic classification of multi-class URL datasets. A synthetic dataset comprising 547,775 URLs was designed to reflect realistic threat distribution: benign (65.74%), phishing (14.46%), defacement (14.81%), and malware (4.99%). Each sample included simple structural features such as URL length, number of dots, HTTPS usage, and keyword indicators. Both models were tested using identical stratified train-test splits with varying sample sizes, including focused experiments on 15,000 and 100,000 entries. Results revealed that both models achieved high recall and precision only for the benign class, while failing to detect minority classes. For Random Forest, precision and recall for benign URLs reached 1.00 but dropped to 0.00 for phishing, defacement, and malware in all test scenarios. Naïve Bayes exhibited similar shortcomings, highlighting the impact of class imbalance and limited feature expressiveness. This research concludes that while Random Forest and Naïve Bayes are computationally efficient, they are inadequate for detecting cyber threats without preprocessing techniques such as SMOTE, cost-sensitive learning, or feature enrichment. Future work will explore adaptive hybrid models with contextual features and deep learning frameworks to enhance multi-class detection in real-world cybersecurity scenarios.
