Abstract

This study aims to compare dryers for cocoa beans. The comparison carried out is a comparison of tools, moisture content, mass, quality of beans, and the time required by each tool in drying. The drying tools used are traditional solar cabinet dryers and solar tunnel dryers. Conventional drying uses direct sun contact on cocoa beans, and solar tunnel dryer uses two types to dry cocoa beans: hot air absorbed by solar collectors and direct sun. In contrast, solar cabinet dryer uses hot air absorbed by solar collectors and driven by fans in the drying room. The research was carried out from 09.00 until 16.00 in 31/2 hours, so in a day, there are three observation data for each research tool. To the research results, the time required for each tool is different, the solar cabinet dryer tool takes four days, and the solar tunnel dryer traditionally takes three days to dry cocoa beans; drying is done 7 hours a day. The highest ambient temperature is up to 36.3oC, the temperature entering the drying chamber for the solar cabinet dryer is up to 54.2oC, and the solar tunnel dryer is up to 51oC. With a mass of 1.5 kg of material dried to 0.50 kilograms, leaving a moisture content of 12%.

Abstract

This study aims to analyze and demonstrate step-by-step bibliometric data analysis using VOSViewer systematically. Step-by-step analysis is provided to make first-time users accessible easier to use VOSViewers. So that learning models can be combined with other areas to study. This study presents data analysis on learning models and their development over the course of ten years (2013–2022) using mapping tools in VOSViewer. The method used is qualitative descriptive to describe the performance of bibliometric analysis by generating a network visualization of the selected topic. From the search results, 999 relevant published journals were found, starting from 2013–2022, which were then grouped into 10 categories according to the year of issue. After grouping journal data, we found that the most published articles in 2015-2020. There are many opportunities to discover new things on this topic. This study is expected to serve as a direction for authors who conduct research and determination of research themes.
