Abstract

In this dynamic technological era, changes permeate various aspects of life. Technology accelerates the shift towards the digital realm, with social media becoming the primary platform facilitating rapid interaction. However, its impact on psychological well-being and communication patterns is not always positive. To address this, an educational training program has been developed to provide adolescents with a deep understanding of the positive use of social media and how to manage its negative effects. The training takes place over one day at SMK Muhammadiyah Bangunjiwo, involving 30 students from grades 11 and 12. The methods include presentations, discussions, and interactive sessions. Survey results show that most students spend considerable time on social media, but they also recognize the importance of understanding its positive and negative impacts. This training successfully increases students' awareness of responsible social media usage, and it is hoped that similar activities can be conducted sustainably. The results indicate that with better understanding, students can optimize the use of social media to support learning and other activities, as well as develop positive character traits. This program contributes to shaping wise and responsible attitudes toward technology use among the younger generation. Awareness of the importance of digital literacy is also increasing, as evidenced by the post-test literacy index increasing by 0.49 compared to the Indonesian average in 2022.

Abstract

Toko sembako merupakan sebuah tempat jual beli barang baku dan terdapat interaksi antara penjual dengan pembeli untuk barang sembako. Toko ini mempunyai persediaan kebutuhan masyarakat sekitar. Beberapa toko sembako kurang mampu mengendalikan persediaan barang secara baik. Hal ini disebabkan karena system yang digunakan masih manual sehingga mengakibatkan banyaknya lembaran kertas catatan. Seringkali terjadi kehilangan lembar catatan oleh karena itu toko sembako tersebut. Akibatnya toko tersebut kesulitan dalam mengetahui barang masuk dan keluar. Untuk mengatasi masalah tersebut bisa digunakan sistem informasi inventaris penjualan barang. Sistem informasi inventaris merupakan alat untuk mengolah data persediaan barang dan digunakan untuk membantu toko sembako dalam mengelola kebutuhan dari toko tersebut. Metode buffer stock merupakan persediaan cadangan yang diadakan untuk melindungi dan menjaga toko sembako dari kemungkinan terjadinya kekurangan bahan (stockout). Dengan menerapkan sistem informasi inventaris menggunakan metode buffer stock maka dapat digunakan sebagai pengendali kestabilan persediaan barang. Hasil pengujuian menunjukkan bahwa sistem layak untuk digunakan.

Abstract

Daerah Istimewa Yogyakarta sebagai kota pelajar mengalami peningkatan jumlah mahasiswa yang berdampak pada meningkatnya kebutuhan hunian, sementara informasi terkait asrama daerah masih terbatas sehingga kurang optimal dimanfaatkan. Penelitian ini bertujuan mengembangkan sistem informasi geografis berbasis web untuk memetakan lokasi asrama daerah di Kota Yogyakarta beserta informasi pendukungnya. Metode yang digunakan adalah User-Centered Design (UCD) melalui tahapan memahami konteks penggunaan, menentukan kebutuhan pengguna, perancangan, dan evaluasi, dengan implementasi menggunakan PHP dan framework CodeIgniter serta teknologi pemetaan digital. Pengujian dilakukan menggunakan Black Box Testing untuk fungsionalitas dan System Usability Scale (SUS) untuk mengukur tingkat kegunaan. Hasil penelitian menunjukkan bahwa sistem mampu menyajikan pemetaan asrama secara interaktif dengan seluruh fitur berfungsi dengan baik, serta memperoleh skor SUS sebesar 81,83 yang termasuk kategori acceptable dan excellent, sehingga sistem dinilai layak digunakan untuk membantu masyarakat dan mahasiswa dalam memperoleh informasi asrama daerah di Kota Yogyakarta

Abstract

The rapid digital transformation requires students to possess efficient and structured research literacy. This Community Empowerment Program (Prodamat) aims to enhance the research capacity of students at Politeknik Mitra Karya Mandiri through a "Smart Research in the Digital Era" approach. The activity was conducted utilizing a participatory training and mentoring method focusing on three main pillars: Systematic Literature Review (SLR) methodology, ethical Artificial Intelligence (AI) utilization, and the mastery of scientific publication tools. The implementation process included comprehensive guidance on defining research questions using the PICOC framework, leveraging AI-based search tools like Elicit and Semantic Scholar with strict adherence to the Human-in-the-Loop principle to mitigate AI hallucinations, and integrating reference management software such as Zotero and Publish or Perish. The results indicate a significant improvement in students' understanding and technical skills in extracting literature data, measuring publication impact, and automating reference management. In conclusion, the integration of the SLR method, ethical AI utilization, and digital reference tools optimally enhances the efficiency and quality of students' scientific writing while strictly maintaining academic integrity for future publications.

Abstract

The increasing demand for digital services requires network architectures that are flexible, programmable, and efficient in utilizing available bandwidth. This study evaluates the performance of Software-Defined Networking (SDN) and a conventional network on an identical Fat-tree k = 4 topology. A quantitative experiment was conducted in Mininet using Open vSwitch, OpenDaylight, OpenFlow 1.3, iPerf3, and ping. Traffic loads were configured at 25%, 50%, and 75% of a 100 Mbps bottleneck-link capacity, with ten repetitions per scenario. Performance was assessed using throughput, round-trip latency, packet loss, and bandwidth efficiency. SDN achieved an average throughput of 81.8 Mbps compared with 60.8 Mbps for the conventional network, reduced average latency from 21.8 ms to 17.1 ms, and reduced packet loss from 2.3% to 0.8%. Bandwidth efficiency increased from 60.8% to 81.8%, equivalent to a relative improvement of 34.5%. A paired-sample t-test across the three load-level means showed a significant throughput difference (p = 0.018), whereas latency (p = 0.088) and packet loss (p = 0.105) were not significant at α = 0.05. The findings indicate that centralized flow control and multipath utilization improve performance under increasing traffic loads, although validation on physical testbeds and larger paired samples remains necessary.

Abstract

Purpose: Heart disease is the leading cause of death throughout the world, especially in developing countries like Indonesia. Modern approaches for diagnosing and managing heart disease rely on machine learning due to the complexity of medical data. Among the biggest challenges in using machine learning is clustering heart disease patients. This study aims to develop a machine-learning model using K-means clustering to determine the severity and level of patient emergencies. The specific objective of the model is to find the optimal number of clusters using the Elbow Method. Methods/Study design/approach: Model development using a dataset from the Kaggle Repository consisting of 303 patient data. Each data point consists of the attributes age, gender, type of chest pain, blood pressure, serum cholesterol level, blood sugar, electrocardiography results, maximum heart rate, angina, ST depression, and segment slope ST. The combination of the K-means clustering algorithm and the Elbow Method is expected to find the optimal number of clusters in the developed model. Result/Findings: The results of building a machine learning model show that k-means clustering is quite effective in clustering heart disease patients. For the model built with 303 data points, the elbow method successfully identified the optimal number of clusters, resulting in two clusters (k=2), where the elbow point on the graph shows a significant decrease in the Sum of Squared Errors (SSE). Novelty/Originality/Value: This study combines the k-means clustering algorithm and the elbow method to determine the severity and level of patient emergencies. The clustering model produces specific risk clusters that help doctors determine more appropriate interventions.
