Abstract

This community service aims to enhance the competency of SMA Cinta Kasih Medan teachers in utilizing information technology (IT) to support teaching effectiveness in the digital era. The importance of IT training is emphasized given the identified initial problems of varying digital skills among teachers and minimal use of interactive media and online learning platforms. The methods employed include training, workshops, and mentoring. The implementation stages cover identifying teacher needs through surveys and interviews, developing relevant training modules (encompassing Google Classroom, interactive presentations, simple video creation, and effective utilization of online learning resources), conducting training with demonstration and direct practice methods, and continuous mentoring and evaluation. The activity was participated by 15 SMA Cinta Kasih Medan teachers with a 100% attendance rate. The main results indicate that most teachers successfully mastered the taught skills, with proficiency percentages reaching 93% for virtual classroom management and 100% for utilizing online learning resources. This training positively impacted teachers' knowledge, skills, and confidence in integrating IT, potentially increasing student engagement and diversifying teaching methods. The training successfully enhanced teachers' digital competency significantly, making it a model for sustainable educational development.

Abstract

Perusahaan merupakan organisasi yang mempunyai berbagai tujuan baik jangka panjang maupun jangka pendek. Salah satu tujuan yang penting untuk dicapai adalah pencapaian laba optimum. Laba dan penetapan harga jual sangat berkaitan dengan akuntansi pada perusahaan, sehingga perlu diolah secara tepat dan teliti. CV. XYZ merupakan sebuah perusahaan yang bergerak di bidang penjualan blinds, curtain, insect screen dan wallpaper. Pada kesehariannya, perusahaan menjual tirai kepada supplier ataupun pelanggan. Namun pada praktiknya, perusahaan sering kesulitan dalam menentukan harga jual produk yang dipasarkan dikarenakan seringkali produk yang dijual terlalu murah sehingga tidak dapat menutupi biaya operasional. Selain itu tidak adanya pengelolaan akuntansi yang baik pada perusahaan membuat perusahaan seringkali salah dalam mengelola keuangan mereka. Oleh karena permasalahan tersebut, maka perlu dibangun sebuah sistem informasi akuntansi agar dapat menyelesaikan permasalahan perusahaan. Hasil dari penelitian ini berupa sistem informasi akuntansi dengan penerapan metode Cost Of Good Solds (COGS) dalam membantu penentuan harga jual produk perusahaan.

Abstract

AI Chatbot is a computer program integrated with artificial intelligence designed to interact with humans and provide useful information. AI Chatbot offers anonymity, one of the factors motivating someone to use it since they feel safe. Indonesian students nowadays inhibit shyness to ask questions and participate in learning due to anxiety factors and fear of negative judgment. Therefore, it is necessary to conduct a test to understand the extent of acceptance factors of AI Chatbots. This research aims to examine the effect of anonymity variable on the use of AI Chatbots among university students at Medan using the UTAUT2 model. A survey was conducted on 421 students. Using the Structural Equation Modeling (SEM) model with the help of SmartPLS software, this study introduces the anonymity variable in the UTAUT2 model, which has a positive and significant effect on students’ behavioral intention to use AI Chatbots. These findings also show that price value and habit have a positive and significant effect on behavioral intention, also habit and behavioral intention effect students’ behavior towards AI Chatbots at Medan. However, performance expectancy, effort expectancy, social influence, facilitating conditions, and hedonic motivation do not affect the students’ behavioral intention and behavior towards AI Chatbots

Abstract

Depresi pada remaja merupakan salah satu masalah kesehatan mental yang dapat memengaruhi kesejahteraan psikologis, prestasi akademik, dan interaksi sosial. Identifikasi faktor-faktor yang berkontribusi terhadap risiko depresi diperlukan untuk mendukung upaya deteksi dini dan pencegahan yang lebih efektif. Penelitian ini bertujuan mengidentifikasi faktor dominan yang berkontribusi terhadap prediksi risiko depresi remaja menggunakan Extreme Gradient Boosting (XGBoost) dengan interpretasi SHapley Additive exPlanations (SHAP). Penelitian memanfaatkan dataset publik yang terdiri atas 1.200 sampel remaja dengan atribut karakteristik individu, kondisi psikologis, penggunaan media sosial, dan aspek gaya hidup. Untuk mengatasi ketidakseimbangan kelas digunakan pendekatan scale_pos_weight, sedangkan evaluasi model dilakukan menggunakan Repeated Stratified Cross Validation. Hasil pengujian menunjukkan rata-rata F1-score sebesar 96,11% dengan standar deviasi 5,66%, yang mengindikasikan performa klasifikasi yang baik dan konsisten. Analisis SHAP menunjukkan bahwa sleep_hours, stress_level, daily_social_media_hours, dan anxiety_level merupakan variabel yang memberikan kontribusi terbesar terhadap prediksi model. Temuan ini menunjukkan bahwa pada dataset yang digunakan, berkurangnya durasi tidur, tingginya tingkat stres dan kecemasan, serta penggunaan media sosial yang lebih intens berkontribusi terhadap peningkatan prediksi risiko depresi. Selain menghasilkan performa klasifikasi yang baik, pendekatan XGBoost dengan SHAP juga meningkatkan transparansi model dalam menjelaskan kontribusi masing-masing variabel terhadap hasil prediksi. Hasil penelitian ini bersifat prediktif berdasarkan dataset yang digunakan dan tidak dimaksudkan sebagai dasar diagnosis klinis depresi.
