Abstract

Malinau Robusta coffee demonstrates untapped potential within the specialty coffee market. This study aims to evaluate the quality of Malinau coffee comprehensively and benchmark it against prominent specialty coffees such as Gayo, Toraja, and Kintamani. A descriptive quantitative method was employed to analyze critical parameters including caffeine content, moisture level, defect value, impurity level, grain size, and flavor profile. Coffee samples were gained from nine coffee-producing villages in Malinau Regency, involving 28 farmers covering 190 ha of coffee plantations. The results identified distinct strengths of Malinau coffee, notably its low moisture level (10.2%) and high caffeine content (1.94%) among the samples, offering a strong and intense flavor profile including chocolatey, a bitter aftertaste, and fruity undertones. Challenges for Malinau coffee includes high defect value (65.7/300 g) and impurity level (0.6%), which undermine its marketability in premium segments. To bring Malinau coffee up to par with other established specialty coffees, improvements in post harvest handling are needed, particularly sorting, quality control and consistent processes methods. By adopting innovative cultivation and processing, Malinau coffee holds strong potential as a competitor of specialty coffee, both for domestic and global markets while highlighting its unique regional identity. Keywords: Malinau coffee, North Kalimantan, Quality improvement, Robusta, Specialty coffee.

Abstract

Changing professions is a process in which a person switches from one job or profession to another, often for a significantly different job, driven by factors such as population growth, demands for basic materials, especially rice, and the need for rice plants. This study aims to identify and understand the factors influencing the occupational shift among rice paddy farmers in Nunukan Regency (Case Study: Mansappa Village, South Nunukan District). The sampling technique used in this research is the census method, involving 30 respondents who shifted from rice paddy farming to seaweed cultivation. The research data were analyzed using quantitative descriptive methods, validity and reliability tests, classical assumption testing, coefficient of determination (R²), multiple linear regression, F-test, and t-test. The factors influencing the occupational shift of rice paddy farmers include economic, social, and technical factors, supported by indicators such as price, income, marketing, social environment, family, government policy, climate, and crop cultivation. The analysis yielded an R² value of 29.1%, with the multiple linear regression equation: Y = 3.839 + 0.250 X₁ + 0.538 X₂ + 0.124 X₃. The F-test showed that economic, social, and technical factors simultaneously influence the occupational shift of rice paddy farmers in Nunukan Regency. Based on the t-test, Social factors have a significant influence on the transition of rice farmers' professions in Nunukan Regency (p-value = 0.036).
