Abstract

This study aims to modify the nutmeg harvesting tool pole model prototype 1 and test the performance of nutmeg harvesting tool pole model that has been modified or harvesting tool DTR TETA 19. This study uses experimental methods, tools that have been modified and then tested to determine the performance of the tool by calculating the harvesting capacity of the fruit/minute and also the capacity of the fruit/hour. The data obtained are arranged in Tabular Form and analyzed descriptively. The conclusion of this study is DTR Teta 19 harvesting tool is superior to the previous tool or nutmeg harvesting tool pole model prototype 1, where DTR Teta 19 tool has an average capacity with two harvests of 199 pieces/hour, while the harvesting capacity of the prototype 1 harvesting tool with one harvest of 152 pieces / hour has a difference of 47 pieces (harvesting with a tool length of 200 cm). As for harvesting with a tool length of 300 cm has a difference in harvesting capacity of 56 pieces / hour where the tool DTR TETA 19 superior. and harvesting with a tool length of 400 cm harvesting tool DTR TETA 19 is superior to the difference in harvesting capacity of fruit / hour which is 21 pieces.

Abstract

Postharvest damage to potatoes can occur due to plant physiological disorders, such as evaporation (transpiration), respiration (respiration), tubers sprouting, and tubers becoming too ripe. This research aims to design, manufacture, and test an evaporative cooling device using a direct spray method from a fan into a room or box by conducting technical tests about temperature, humidity (RH), signs of potato damage, weight loss, and water content. The test was carried out using an evaporative cooling device (evaporative cooler) for 30 days.    This research tested the effectiveness of the evaporative cooling system compared to room outside storage on potato quality for 30 days observationally. The results show that evaporative cooling equipment can prolong the shelf life of fresh potatoes in tropical areas according to physical parameters such as signs of damage to potatoes during storage, water content, and percentage of weight loss. For future development, increasing the fan and cooling pad to medium size is necessary for more effective equipment. An evaporative cooler is a cost-efficient and sustainable method for preserving agricultural produce in rural areas far from urban centers.

Abstract

This study aims to analyze and compare the effectiveness of four types of packaging, namely: vacuum, non-vacuum, plastic wrapping, and perforation in maintaining the quality of carrots (Daucus carota L.) during cold storage until signs of damage appear, based on parameters of changes in weight, water content, color, and texture. The method used is an experiment with four treatments of packaging types on carrots stored in a refrigerator at a temperature of 2°C-4°C for 30 days. Observations were made on changes in weight, color (L*, a*, b*), texture, and moisture content of the carrots in each treatment. The results of the study show that in vacuum packaging, the average weight change was 0.00-0.35 g (23 days), the average moisture content change was 87%-86% (30 days), the average L* color change was 54.83, a* of 33.59, and b* of 54.83, and a texture of 4.73-3.40 N. In non-vacuum packaging, the average weight change was 0.00-0.20 g (17 days), the average moisture content change was 86.33%-86.0% (30 days), the average change in color L* was 56.72, a* was 30.10, and b* was 56.72, and the texture was 4.73-2.93 N. In perforated packaging, the average change in weight was 0.26-8.61 g (30 days), the average change in moisture content was 87%-86% (30 days), the average change in color L* was 55.04, a* was 27.32 and b* was 55.03, and the texture was 4.73-2.93 N (30 days). In perforated packaging, the average weight change was 0.00-21.74 g (15 days), the average moisture content change was 86.50%-85.0% (30 days), the average color change L* was 54.35, a* 29.69, and b* 54.35 (30 days), and the average texture was 4.73-2.03 N (30 days). Based on the results of a comparative analysis of the four types of packaging, plastic wrapping proved to be the most effective in maintaining carrot quality during cold storage until signs of damage appeared. Keywords: Carrots, Vacuum Packaging, Non-Vacuum Packaging, Plastic Wrapping, Perforated Plastic.
