Abstract

Kegiatan Pengabdian kepada Masyarakat ini dilaksanakan dengan tujuan meningkatkan literasi digital serta efektivitas komunikasi dan informasi bagi anggota Komite RA Al Fariq melalui pemanfaatan media sosial. Permasalahan utama yang dihadapi adalah rendahnya pemahaman anggota komite dalam menggunakan media sosial secara tepat, kurangnya tata kelola komunikasi digital, serta keterlambatan penyebaran informasi. Untuk menjawab tantangan tersebut, tim pelaksana mengadakan sosialisasi dan pelatihan penggunaan media sosial, meliputi literasi digital dasar, manajemen grup komunikasi, etika berinteraksi, serta penyusunan Standar Operasional Prosedur (SOP) pemanfaatan media sosial di lingkungan sekolah. Kegiatan diikuti oleh 20 peserta yang terdiri dari guru dan perwakilan komite. Hasil kegiatan menunjukkan peningkatan signifikan pada aspek pengetahuan, keterampilan, dan kesadaran digital, yang dibuktikan dengan kenaikan rata-rata skor post-test lebih dari 50% dibandingkan pre-test. Selain itu, komunikasi internal komite menjadi lebih terstruktur dengan terbentuknya grup WhatsApp resmi sebagai saluran utama koordinasi. Peserta juga mulai memanfaatkan platform lain seperti Facebook dan Instagram untuk memperluas jangkauan informasi sekolah. Kegiatan ini tidak hanya berhasil memperkuat peran media sosial sebagai sarana komunikasi dan informasi, tetapi juga membentuk budaya digital yang lebih bijak, produktif, dan beretika di lingkungan pendidikan anak usia dini.

Abstract

Currently, the data registration procedure required by the North Sumatra Provincial General Election Commission is still done traditionally. Therefore, all legislative candidates from political parties must directly provide the required data in document format or written sheets. As a solution to this problem, it is recommended that an application be used to check and register the data required by the North Sumatra Provincial General Election Commission. This application uses the PHP programming language, MySQL as a database, and the waterfall method will be applied to computerize the process, making it faster and more accurate. The design of this application consists of two elements: the North Sumatra Provincial General Election Commission administrator, who handles the checking and filtering of the required data for each legislative candidate, and the political party administrator, who inputs the data for the legislative candidate. The implementation of this application is expected to increase efficiency, reduce errors, and support transparency in the legislative candidate registration process.

Abstract

Equal access to education remains a key challenge in the development of human resources at the regional level. Asahan Regency is home to a variety of formal and non-formal educational institutions spread across multiple districts. However, the distribution data of these institutions is still fragmented and not yet integrated into a centralized system. This study aims to map the locations of formal and non-formal schools registered under the Department of Investment and One-Stop Integrated Services (DPMPTSP) in Asahan Regency using Geographic Information System (GIS) technology. The developed system presents spatial information through an interactive digital map that helps the public locate schools according to their needs and supports the local government in planning equitable distribution of educational facilities. In addition, the system includes a feature that allows school administrators to upload administrative documents digitally, thereby streamlining the registration process at the Public Service Mall. The research employs a descriptive qualitative approach with data collection techniques such as observation, documentation, and interviews. The results show that GIS implementation effectively provides accurate visualizations of school distribution patterns and helps identify areas lacking in educational facilities. The system also enhances the efficiency of the administrative process for school licensing.

Abstract

This study presents a comparative study of hyperparameter optimization methods applied to the Light Gradient Boosting Machine (LightGBM) algorithm for asthma prediction. Traditional machine learning models often face limitations in accuracy and generalization capabilities due to suboptimal hyperparameter configurations. To address these challenges, this study evaluates and compares four approaches: Default LightGBM, RandomizedSearchCV, Optuna Optimization, and Bayesian Optimization. Experimental results show that Bayesian Optimization provides the best performance with an accuracy of 78%, a precision of 0.7778, a recall of 0.7778, an F1-score of 0.7778, and an ROC-AUC of 0.975. These findings emphasize the importance of selecting an appropriate optimization strategy to improve model performance in clinical prediction tasks. Overall, this study confirms the effectiveness of Bayesian Optimization in improving the predictive capabilities of LightGBM and provides an important contribution to the development of decision support systems in healthcare, particularly in the diagnosis and management of asthma

Abstract

Proses penentuan siswa yang layak menerima beasiswa berprestasi seringkali hanya berdasarkan seleksi berkas, yang memakan waktu lama dan dapat menghasilkan keputusan yang kurang akurat. Oleh karena itu, penelitian ini bertujuan untuk mengembangkan sistem pendukung keputusan yang mempercepat proses seleksi siswa penerima beasiswa berprestasi. Metode yang digunakan dalam penelitian ini adalah ARAS (Additive Ratio Assessment) dan TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution). Kedua metode ini dipilih karena mampu menyeleksi alternatif terbaik berdasarkan pembobotan dan memilih tujuan berdasarkan kriteria yang berbeda, yaitu benefit dan cost. Metode ARAS menghasilkan ranking berdasarkan perbandingan fungsi utilitas alternatif dengan nilai fungsi utilitas optimal, sementara metode TOPSIS menghasilkan ranking berdasarkan jarak terpendek dengan solusi ideal positif dan jarak terpanjang dengan solusi ideal negatif. Dari nilai-nilai tersebut, alternatif yang memenuhi kriteria ditetapkan sebagai siswa penerima beasiswa berprestasi melalui perhitungan menggunakan metode ARAS dan TOPSIS. Hasil uji korelasi Rank M Arsya Almusa menunjukkan nilai 1,0546 untuk ARAS dan 0,8739 untuk TOPSIS. Hasil perhitungan secara manual dan melalui sistem memberikan hasil yang sama, sehingga sistem dapat digunakan untuk menentukan siswa penerima beasiswa berprestasi.
