dengan pengabdian kita kepada masyarakat. Sebagai seorang akademisi baik dosen dan mahasiswa harus mampu bekerjasama dalam meujudkan Tri Darma perguruan tinggi dimana tempat kita membagi dan menimba ilmu pengetahuan. Pengabdian kepada masyarakat adalah tindakan nyata yang dapat kita lakukan untuk menambah wawasan masyarakat terhadap informasi yang akan kita bagikan, sehingga membawa kontribusi positif dalam masyarakat. Apalagi sekarang lagi hangat-hangatnya memperbincangkan tentang pemilihan kepala daerah, oleh karena itu penyuluhan tentang kepemimpinan dianggap perlu untuk di sosialisasikan kepada masyarakat. Harapan kedepannya adalah masyarakat mampu memilih pemimpin yang dapat menjadi contoh baik dalam setiap tindakan dan perkataannnya. Masyarakat diharapkan lebih hati-hati dalam memilih calon kepala daerah, tidak mudah terpengaruh citra dan kekuasaan yang dapat mendatangkan kerudian dalam masyarakat itu nantinya. Selain itu masyarakat tidak perlu takut terhadap tekanan yang mungkin saja datang untuk memaksa memilih jagoan mereka, masyarakat harus mendapatkan pencerahan tentang bagaimana hukum itu berlaku di kalangan masyarakat. Untuk itu selain membahas masalah kepemimpinan Universitas asahan juga bekerjasama dengan Yayasan Lembaga Bantuan Hukum – Cakrawana Nusantara Indonesia untuk memberi pemahaman kepada masyarakat tentang hukum, apa yang harus dilakukan masyarakat apabila tersangkut permasalahan hukum di lingkungannya, mengetahui hak dan kewajibannya dalam mentaati hukum tersebut. Harapan terbesarnya masyarakat di desa antara tidak tabu lagi terhadap permasalahan hukum, masyarakat desa antara berani untuk menghadapai permasalahan hukum yang mereka hadapi, masyarakat desa antara mampu memilih pemimpin yang tepat untuk memimpin daerah mereka.

Abstract: The application form of a series of educational theories that have been studied on campus will certainly be more useful if the theories of science are shared for the community. This activity is called our devotion to the community. As an academic both lecturers and students should be able to work together in realizing Tri Darma college where we share and gain knowledge. Community service is a real action that we can do to increase society's insight into the information we will share, thus bringing a positive contribution to society. Especially now more warmly discussed about the election of regional heads, therefore counseling about leadership is considered necessary for the socialization to the community. The future expectation is that people are able to choose leaders who can be good examples in every action and perfomance. The community is expected to be more careful in choosing candidates for regional heads, not easily influenced by the image and power that can bring in the society later. In addition people should not be afraid of the pressures that might come to force their heroes, the public should get an enlightenment about how the law applies to the public. In addition to discussing the issue of leadership, the University of Asahan also cooperates with the Legal Aid Foundation - Cakrawana Nusantara Indonesia to provide an understanding to the public about the law, what should the community do when it comes to legal issues in its environment, knowing its rights and obligations in complying with the law. The greatest hope of the community in the village between no longer taboo on legal issues, the villagers between daring to face the legal problems they face, the villagers between able to choose the right leader to lead their area.

society needs. Vocational High School is a vocational school that is required to be ready to enter the world of work, therefore the SMK graduates are required to have the skills and knowledge that will be used in the workplace. Students of vocation especially in the majors of Software Engineering must have skills in computer science, such as programming skills. In the 2013 curriculum used by SMKN1 Air Joman, there are already programming subjects, but still local content and yet the discovery of mobile programming. Though mobile programming is currently one of the most popular programming, especially Android. This is not separated from the rapid development of the Android operating system, so people are competing to make the application. The advantages of android is its opensource and easy to develop, supported by a lot of android users including SMK students, so students can build and develop an android application and implement it on their respective devices so that it can be used as needed and not close possibly to be commercialized.

Abstract:Abstract: Query performance is a critical factor in managing large-scale databases. One of the most widely used optimization techniques is indexing. This study aims to analyze the impact of indexing on query performance…
in PostgreSQL, compare the effectiveness of B-Tree and Hash indexes, and evaluate their influence on query planner decisions. A quantitative experimental approach was employed using the TPC-H benchmark dataset at scale factors SF0.1, SF1, and SF10. Experiments were conducted using EXPLAIN ANALYZE on exact match, range, and join queries under three conditions: without indexing, with B-Tree indexing, and with Hash indexing. The results demonstrate that indexing significantly improves query performance. For exact match queries on the SF10 dataset, execution time decreased from 93.36 ms without indexing to 0.034 ms using B-Tree and 0.045 ms using Hash indexes. For join queries, execution time was reduced from 857.77 ms to 0.180 ms using B-Tree and 0.079 ms using Hash indexes. B-Tree showed consistent performance across different query types, while Hash achieved the best results for equality-based queries. Furthermore, index usage influenced query planner decisions in selecting more efficient execution strategies. These findings indicate that appropriate index selection can substantially improve data access efficiency in PostgreSQL.

Abstract:Abstract: Existing IoT anomaly detection studies have achieved high classification performance, but most focus on accuracy and F1-score without explicitly controlling the false positive rate (FPR). In addition, many approaches…
oaches rely on a single detection perspective, limiting their operational reliability. To address this gap, this study proposes a hybrid anomaly detection framework integrating Long Short-Term Memory (LSTM), Shannon entropy, and autoencoder reconstruction error. Shannon entropy is incorporated as an additional feature, while LSTM and the autoencoder capture temporal and reconstruction characteristics. The resulting hybrid representation is processed by a constraint-based threshold selection mechanism that enforces FPR . Experiments on the TON-IoT and Edge-IIoTset datasets achieved average F1-scores of 0.9250 and 0.9934, while maintaining average FPR values of 0.0091 and 0.0714, respectively. Analysis of entropy distributions showed consistent differences between normal and anomalous traffic across both datasets, indicating that Shannon entropy provides discriminative information for anomaly detection. These results demonstrate strong detection performance with controlled false alarms, while ablation studies confirm the significant contribution of Shannon entropy to overall model performance.

Abstrak: Penelitian deteksi anomali Internet of Things (IoT) telah menunjukkan performa klasifikasi yang tinggi, namun sebagian besar masih berfokus pada accuracy dan F1-score tanpa mengendalikan false positive rate (FPR) secara eksplisit. Selain itu, banyak pendekatan hanya memanfaatkan satu perspektif deteksi sehingga reliabilitas operasionalnya masih terbatas. Untuk mengatasi kesenjangan tersebut, penelitian ini mengusulkan kerangka deteksi anomali hybrid yang mengintegrasikan Long Short-Term Memory (LSTM), Shannon entropy, dan autoencoder reconstruction error. Shannon entropy digunakan sebagai fitur tambahan, sedangkan LSTM dan autoencoder menangkap karakteristik temporal dan deviasi rekonstruksi. Representasi hybrid yang dihasilkan kemudian diproses melalui mekanisme constraint-based threshold selection dengan batas FPR . Hasil pengujian pada dataset TON-IoT dan Edge-IIoTset menghasilkan F1-score rata-rata sebesar 0,9250 dan 0,9934, dengan FPR rata-rata sebesar 0,0091 dan 0,0714. Perbedaan nilai entropy yang konsisten antara trafik normal dan anomali pada kedua dataset menunjukkan bahwa Shannon entropy menyediakan informasi diskriminatif untuk deteksi anomali. Hasil tersebut menunjukkan performa deteksi yang kuat dengan false alarm yang terkendali, sementara studi ablasi mengonfirmasi kontribusi signifikan Shannon entropy terhadap performa model.

simple criteria such as Grade Point Average (GPA) thresholds and subjective judgment, without systematic data analysis. This study aims to apply the Fuzzy C-Means (FCM) clustering algorithm to objectively group students based on their academic achievement levels. The dataset consists of academic records from 179 sixth-semester students of the Computer Science Study Program at Universitas Islam Negeri Sumatera Utara, where 160 eligible students are processed in the FCM calculation. Three variables are used: cumulative GPA, total completed credits, and the total number of low grades (D/E). The FCM algorithm automatically performs the mapping and groups students into three categories, namely excellent, stable, and at-risk students. Cluster quality is evaluated using the Silhouette Score and Davies–Bouldin Index, showing satisfactory clustering performance. The results indicate that the proposed approach provides a data-driven and objective basis for academic decision support.
