Abstract

Program Kemitraan Masyarakat ini dilaksanakan pada usaha bakery, Novri Bakrie dan Dapoer Bunda B&B, yang berlokasi di Desa Sidomulyo, Kecamatan Binjai, Kabupaten Langkat, sekitar 35 km dari Lembaga Penelitian dan Pengabdian Masyarakat Universitas Negeri Medan, dengan jarak tempuh sekitar satu jam perjalanan menggunakan mobil. Para mitra menghadapi beberapa tantangan, yaitu: 1) Produk yang dihasilkan belum mampu memenuhi kebutuhan penjualan karena keterbatasan kapasitas peralatan yang dimiliki, 2) Peralatan produksi yang sudah usang, sederhana, dan tidak higienis, 3) Minimnya modal usaha yang menyebabkan mitra tidak mampu mengganti peralatan yang ada saat ini, 4) Manajemen usaha yang masih sederhana dan catatan pembukuan yang kurang memadai, serta 5) Pembukuan yang masih dilakukan secara manual. Metode pendekatan yang digunakan dalam program pengabdian ini meliputi pelatihan, pendampingan, dan demonstrasi penggunaan alat. Hasil dari kegiatan ini adalah penyerahan alat Teknologi Tepat Guna (TTG) berupa oven roti, disertai praktik penggunaannya, serta pelatihan dan pendampingan dalam manajemen usaha dan pembukuan yang lebih terstruktur, rapi, dan praktis.

Abstract

In the modern era of education, the implementation of the Outcome-Based Education (OBE) Curriculum and the mastery of four key literacies, human, language, data, and digital literacy are urgent needs for educators in higher education institutions. At the State University of Medan, lecturers' understanding of the OBE curriculum and these literacies is crucial for improving the quality of the learning process and student outcomes. This study aims to optimize the understanding of lecturers at the State University of Medan regarding the OBE curriculum and the required literacies to effectively integrate 21st-century skills into teaching and learning activities. The research employs a qualitative descriptive approach, using data collection techniques such as surveys, interviews, and focus group discussions (FGDs) involving 100 lecturers from various faculties at the State University of Medan. Data analysis was conducted using the triangulation method to obtain a comprehensive understanding of the lecturers’ levels of understanding and the challenges they face in implementing the OBE curriculum and the four literacies. The findings indicate that lecturers’ understanding of the OBE curriculum is varied, with some lecturers demonstrating a good grasp, while others require improvement in their knowledge and skills. Human and language literacies are relatively well-mastered by most lecturers; however, data and digital literacy remain challenges that need to be addressed. In conclusion, continuous professional development strategies, such as training and workshops, are required to enhance lecturers' understanding of the OBE curriculum and the four literacies. The implications of this study highlight the importance of institutional support in providing adequate resources and facilities, as well as encouraging collaboration among lecturers to strengthen pedagogical capabilities relevant to the demands of modern education.

Abstract

Economic development is one of the important goals to be achieved by a country. Because basically economic development is an effort and policy with the aim of expanding employment opportunities, raising the standard of living of the people, and improving the regional regional economy. Gross Regional Domestic Product is an indicator that can be used to see economic growth in a region. North Sumatra's GRDP growth rate recorded in the Central Bureau of Statistics of North Sumatra has fluctuated. One way to find out if GRDP has increased or decreased is to use forecasting. In various fields, forecasting systems are needed that must be accurate to anticipate future events. One of the methods used is regression analysis, including polynomial and exponential regression, the data used is North Sumatra GRDP Growth Rate data from 2011 to 2021 where the X variable is the year and the Y variable is the GRDP growth rate each quarter, and the best method will be determined in this research. From the results obtained using the help of the Matlab application, the best forecasting model is by looking at the MSE which is close to zero where the MSE values are regression, namely: 1st Order Polynomial (MSE: 1.98e-05); Order 2 Polynomial (MSE: 0.0023); Order 3 Polynomial (MSE: 1.85e-04); Order 4 Polynomial (MSE: 12.65); Order 5 polynomial (MSE: 8.66); Exponential (MSE: 0.2447).

Abstract

Public opinion on PON 2024 (National Sports Week in Indonesia) became a trending topic on X (formerly Twitter), reflecting both positive and negative sentiments. Understanding these sentiments is important for evaluating the event and preparing for the upcoming. However, baseline SVM algorithms using standard kernel functions are not optimized for text similarity and limit performance in sentiment analysis. This research proposes cosine similarity as a substitution for the kernel function on SVM, enhancing the sentiment analyzer's performance on public opinions about PON 2024. The approach leverages cosine similarity's strength in handling text-based data. The key contribution of this research is the integration of cosine similarity into the SVM algorithm as a replacement for kernel functions, improving performance in sentiment analysis. Additionally, this study offers a comprehensive comparison with baseline SVM and provides actionable insights for upcoming PON. The study collected 1,011 tweets related to PON 2024 using web scraping and the Twitter API, followed by labeling sentiments as positive, neutral, or negative. Several preprocessing techniques also were applied to prepare the data. Two models were developed: baseline SVM and another using SVM integrated with cosine similarity, both evaluated through accuracy, precision, recall, and F1-score. The baseline SVM achieved 85.1% accuracy, 85% precision, 83% recall, and 83.3% F1-score, struggling particularly with negative sentiment. Opposite, by integrating cosine similarity on SVM, the performance improved to 88.73% accuracy, 88.3% precision, 89.3% recall, and 88.3% F1-score—a boost of 3.3-6.3%. Additionally, the public opinion revealed that positive sentiments mostly focused on athlete achievements and medal awards, while negative sentiments highlighted issues like referee performance and specific sports (e.g., football). This approach can serve as a valuable tool for event organizers to identify public concerns and maintain positive aspects for the upcoming PON 2028.
