Abstract

Coffee, originating in the 9th century Ethiopia and later expanding across North Africa and tropical regions globally, remains a crucial commodity. Indonesia, recognized for its robust coffee industry, ranks third worldwide in production, contributing 8% of the global supply. However, the drying process poses challenges to Indonesian farmers due to traditional methods and variable weather conditions. This research aims to evaluate a coffee dryer utilizing forced convection with a suction blower to optimize drying parameters for coffee beans. The study employs a horizontal mill dryer with a heated drum for drying experiments. Results demonstrate that the dryer effectively reduces the moisture content of post-harvest coffee cherries to 2%. In the initial test, 20 kg of coffee dried over 7.5 hours at 75℃ decreased from 61.66% to 5.3% moisture, while a subsequent test with 17 kg dried over 4 hours reduced from 36% to 2% moisture content. The findings conclude that the suction blower-equipped dryer meets Indonesian National Standards (SNI), achieving the requisite 12% moisture content for post-harvest coffee.

Abstract

This research aims to analyze the influence of Work Discipline, Work Environment and Work Motivation partially and simultaneously on Employee Performance at the North Hulu Sungai Regency Education Service. This research was conducted to explain the variables that will be studied and to see the influence of the Work Discipline (X1), Work Environment (X2), and Work Motivation (X3) variables on the Employee Performance variable (Y). The location of this research is the North Hulu Sungai District Education Office. Using saturated sampling, the sample size was 43 samples. The data collection method used was a questionnaire. The analytical method used is descriptive statistical analysis and multiple linear regression analysis. The research results show 1) that simultaneously (together), Work Discipline, Work Environment and Work Motivation have a significant effect on Employee Performance at the North Hulu Sungai Regency Education Service. Likewise individually (partially), 2) Work Discipline has a significant effect on Employee Performance, 3) The work environment has a significant effect on employee performance, and 4) Work Motivation has a significant effect on Employee Performance at the North Hulu Sungai Regency Education Office. Keywords: Discipline , Environment, Work Motivation, Performance
