Abstract

The rapid development of communication technology has driven high demand for smartphones, including among students. Based on this, this study was formulated to answer the question: "Does brand image influence OPPO smartphone purchasing decisions among students in the Sharia Business Management Study Program at STAIN Mandailing Natal?". This study aims to analyze and measure the extent of brand image's influence on purchasing decisions. This study used a quantitative approach with a questionnaire method of 75 student respondents from the 2021-2024 intake. Data collection techniques included observation, interviews, documentation, and a Likert-type questionnaire. The primary theories used were brand image theory and purchasing decision theory. Data analysis techniques used included validity, reliability, normality, heteroscedasticity, simple linear regression analysis, partial t-test, coefficient of determination (R²), and correlation tests, all using SPSS version 25.The results showed that brand image had a positive and significant effect on OPPO smartphone purchasing decisions among college students, with a calculated t value > t table (17.504 > 1.666). This means that the more favorable students' perceptions of OPPO's brand image, the higher their likelihood of purchasing the product.

Abstract

This livestock business is capable of producing thousands of chickens per harvest with a 30–35-day rearing cycle. However, the farm faces various risks, particularly related to fluctuating chicken mortality rates from the DOC period to harvest. The main contributing factors are suboptimal cage conditions, extreme weather, and chicken stress. The objective was to analyze the various risks that affect broiler chicken productivity. This study used a descriptive qualitative approach through observation, interviews, and document review. The results identified six types of risks. Three risks are categorized as high, namely poor cage hygiene, chicken mortality that can spread viruses, and uneven chicken growth. Two risks are categorized as medium, namely disturbances from predators and extreme weather. Meanwhile, one risk is categorized as low, namely unpleasant odor. This study is expected to serve as a reference in minimizing livestock risks. Recommendations provided include maintaining cage cleanliness regularly, providing balanced nutritional feed, improving biosecurity systems, and anticipating extreme weather and pest animals. By implementing these strategies, it is hoped that livestock productivity can increase and risks can be minimized.
