Abstract

Micro, Small, and Medium Enterprises (MSMEs) are strategic sectors in the Indonesian economy, but often face challenges in efficient and data-driven production management. This article highlights the urgency of the Real Work Lecture (KKN) program as a form of student service in assisting MSMEs, especially in optimizing the production of snacks typical of Tebing Syahbandar. This research aims to optimize the production output of the Untir-untir Titik Factory with an Integer Linear Programming (ILP) approach using the Branch and Bound algorithm. Primary data is obtained through interviews and production documentation, including product type, raw material needs, operational costs, selling prices, and profit margins. The initial analysis was carried out using the simplex method using POM QM software to obtain a linear solution, which was then refined with the Branch and Bound algorithm so that the results were in the form of integers. The results of the study showed that the optimal solution was achieved by producing 25 bales of kolong-kounder and not producing other types of snacks, resulting in a profit of Rp1,650,000 per day. These findings show that the ILP approach with Branch and Bound is able to significantly increase the efficiency and profitability of MSMEs. In addition, this method can be used as a basis for quantitative-based production decision-making. This research also emphasizes the strategic role of KKN in technology transfer and real solution-based assistance for MSME actors in the region, thereby supporting the sustainable strengthening of the local economy.

This research explores the characteristics of communication theory in TVRI Medan broadcasting as an effort to build and strengthen cultural groups in North Sumatra. Using the free interview method with the Head of the Production Section of TVRI Medan in the context of a study visit to the UIN SU Communication Science study program to TVRI Medan. This research also uses library research methods, namely by using various literature in the form of books, scientific works, and national and international journals. This research focuses on the analysis of cultural broadcast programs, namely, Pesona Indonesia as a concrete case study. The results show that communication theory was successfully implemented through collaboration between broadcast communication theory and intercultural communication theory by looking at actual social reality. The implications of these findings provide practical guidance for the development of culture-based broadcasting programs

Abstract

This study aims to examine the influence of social media usage, particularly Instagram, on consumer behavior in the context of fashion product purchases. The method used in this research is a quantitative approach, with data collected through questionnaires distributed to respondents. The results show that Instagram usage has a significant impact on the frequency of fashion product purchases. The t-test reveals that each additional hour of Instagram use per day significantly increases the frequency of fashion purchases. These findings indicate the importance of Instagram as an effective marketing platform in the fashion industry.
