Abstract

This study aims to analyze the profit function of rice farming in Tanah Sepenggal District, Bungo Regency. Specifically, this study (1) describes the characteristics of rice farming, (2) calculates the amount of profit earned by farmers, and (3) identifies the factors that influence the level of profit. The research employed a quantitative descriptive method approach using primary data collected from rice farmers through structured interviews in June- July 2025. Farm profit was calculated as the difference between total revenue and total cost, while the Cobb–Douglas profit function Unit Output Price (UOP) to examine the effect of seed cost, urea fertilizer cost, NPK fertilizer cost, pesticide cost, labor cost, and land rent. The results indicate that seed, pesticide, labor, and land rent costs significantly affect farm profit, whereas urea and NPK fertilizer costs do not. The coefficient of determination (R²) of 0.987 indicates that the model explains 98.7% of the variation in profit.

Abstract

This research aims to describe a general overview of red chili farming in Kayu Aro Sub-district and Kerinci Regency generally, analyze the cost structure and income and the feasibility of red chili farming, and to analysis implementation to rural goverment. This research was conducted in Kayu Aro Sub-district, specifically in Batang Sangir and Sungai Tanduk villages. The number sampled in this study was 54 farmers. Both primary and secondary data were utilized. The data analysis methods used were descriptive analysis and quantitative analysis. The research shows that red chili farming in the research area is a traditional practice that has been passed down through generations and remains deeply rooted in the culture. Consequently, all basic farming activities are based on traditional experiences. The first step in red chili farming is seed preparation, where farmers use local seeds known as LOKER (Local Kerinci), obtained from previous harvests, eliminating the need to purchase seeds. Generally, red chili farmers in the research location have small land holdings where they own on average 0.18 hectares. The red chili farming maintenance activities include transplanting, staking, weeding, fertilization, as well as pest and disease control.  The cost structure consists of fixed costs amounting to IDR 1,413,000/MT/year and variable costs amounting to IDR 27,985,000/MT/year. The income obtained from red chili farming is IDR 18,963,400/farmer/MT. The R/C ratio for red chili farming is 1.70, indicating that the farming activity in the research area is profitable and viable to pursue.

Abstract

This research was conducted in Ibru Village, Mestong District, Muaro Jambi Regency, focusing on turmeric farmers as respondents. The study aimed to achieve three primary objectives: (1) to analyze the production function associated with turmeric farming, (2) to evaluate the level of optimization and economic efficiency in the utilization of production factors, and (3) to determine the optimal use of production inputs in turmeric cultivation. A census approach was employed, encompassing all 26 turmeric farmers in Ibru Village as the study’s respondents. The methodological framework utilized the Cobb-Douglas production function analysis, followed by optimization calculations to assess economic efficiency. The results of the study indicated several key findings: (1) land and labor inputs were found to significantly impact the increase in turmeric production per hectare annually, while the inputs of seeds and compost fertilizers did not show a significant effect on production levels; (2) the current use of land and labor in turmeric farming was identified as economically inefficient; and (3) optimization analysis suggested that there is potential for expanding turmeric farming to 1,925 hectares, with a corresponding increase in labor utilization to 31,213 labor days (HOK). These findings provide valuable insights into the efficiency of production practices in turmeric farming and offer guidance for potential improvements and expansion in the sector.
