Abstract

Regional economic factors, income levels, and the availability of substitutes influence the demand for beef, chicken, and eggs in Indonesia. Beef is considered a luxury commodity in higher-income areas and exhibits greater price sensitivity in lower-GDP regions. Chicken, a staple protein source, generally demonstrates inelastic demand but increases price sensitivity in the lower GDP areas. Eggs, being more affordable, exhibit higher price elasticity, particularly in lower-GDP regions, and often complement beef consumption. This study examines the own-price, cross-price, and income elasticities for beef, chicken, and eggs in Indonesia, comparing these effects across provinces with varying income per capita levels. The research utilized secondary data from the Central Statistics Agency, encompassing per capita commodity consumption, consumption values, and prices from 2013 to 2023 across 33 provinces. The Almost Ideal Demand System (AIDS) model analyzed the interrelated consumption of beef, broiler chicken, and eggs. Certain provinces were excluded due to data limitations, particularly in newly formed regions with insufficient historical records. The findings of this research indicate that price sensitivity, regional economic factors, and consumer preferences influence the demand for beef, chicken, and eggs. Income disparities affect substitution patterns, wherein rising chicken prices lead to increased beef consumption, while eggs complement beef and premium varieties are perceived as luxury goods. Consequently, there is a necessity for policies addressing regional economic disparities, food security, and affordability, especially as premium products such as organic eggs become more prevalent and the cost of animal proteins increases.

Goldfish is in great demand by the people of Southeast Aceh because it is easily obtained in the market and becomes a typical dish. There is an increase in feed prices while output prices are fixed. So many farmers stopped producing but some survived. There is a difference in productivity between farmers who quit and farmers who stay. Farmers must improve production efficiency with the use of the right inputs so as to minimize costs and maximize profits. The study was conducted in Lawe Bulan District with the number of samples used as many as 40 farmers. The analysis used by DEA (Data Envelopement Analysis) to obtain Technical, Allocative and Economic Efficiency values and Tobit Regression Analysis to see the relationship between efficiency and farmer characteristics.

The Economic Efficiency Rate is 0.832 or 83.2%. The results of Tobit Regression are technically significantly positively related to the age of farmers. Allocative efficiency revealed a significant effect at the level of 5% and negatively related between allocative efficiency and education level. The results of the DEA analysis of the level of production efficiency have not been efficient. The Technical Efficiency score has an inefficiency of 24.5%. The allocative efficiency value of inefficiency was 8.1%. The Economic Efficiency score of inefficiency was 16.8%. The results of tobit regression there are sources of inefficiency of socioeconomic variables that become inefficienciesSuch as technical efficiency of education and number of dependents, allocative efficiency of age, education and experience, economic efficiency of experience variables and number of dependents.

Abstract

In the highly competitive beauty product industry, companies are required to implement innovative and relevant marketing strategies to maintain and increase consumer buying interest. Recent phenomena indicate that marketing mix elements (product, price, place, and promotion) are often underutilized or focused too narrowly on a single aspect. Meanwhile, the use of brand ambassadors, particularly South Korean celebrities, has become a dominant trend, believed to build emotional appeal and enhance positive consumer perceptions. This study aims to analyze the influence of the marketing mix and brand ambassadors on buying interest, as well as examine the moderating role of brand ambassadors in this relationship. This research adopts a quantitative associative approach, using questionnaires distributed to consumers exposed to brand ambassador promotional campaigns. Data analysis was conducted using multiple linear regression and moderated regression analysis. The results indicate that both the marketing mix and brand ambassadors have a positive and significant effect on consumer buying interest. However, the role of brand ambassadors as a moderating variable in strengthening the relationship between the marketing mix and buying interest was not consistently significant. These findings emphasize the importance of an integrated marketing strategy that not only leverages the popularity of brand ambassadors but also optimizes all elements of the marketing mix in a way that is appealing, educational, and aligned with contemporary consumer needs.
