Abstract

Coffee cultivation in Indonesia generally only relies on rainfall as a source of water. Drought that occurs in the dry season inhibits growth, reduces yields, and even death of plants. Not all plants are equally resistant to drought conditions. Drought-resistant coffee clones usually develop several resistance mechanisms, including the formation of specific compounds to protect cells and tissues from damage caused by drought stress. Therefore, the objective of this study was to investigate the influence of watering interval on the seedling growth of three clones of Arabica coffee. This study used applying intervals of watering every two, four and six days as first factor and three Arabica coffee clones as second factor, namely Andungsari 2K, S 795, and Andungsari 1. The experimental design used a factorial completely randomized design where every treatment combination had three replications. This study on Arabica coffee nursery lasted for three months. Results obtained in this study demonstrated that combination of watering every four and six days on Andungsari 2K clone had the best values on several observed variables. Number of stomata, leaf thickness, fresh root weight, and root dry weight were larger for watering every six days on the Andungsari 2K clone, meanwhile leaf number, stem diameter, fresh and dry weight of leaves were larger for watering every four days on Andungsari 2K clone. This study showed that there was an interaction between watering intervals and Arabica coffee clones on plant growth. Treatment combination of watering every six and four days on Andungsari 2K clone significantly affect number of stomata, fresh root weight, and root dry weight especially for watering every six days on Andungsari 2K clone.

Abstract

The apple industry in Indonesia, particularly in East Java Province, faces significant challenges related to fruit spoilage, which can result in substantial economic losses. One potential solution to address this issue is the application of natural-based edible coatings. This study aims to examine the effects of combining torch ginger (Etlingera elatior) flower extract and mimosa (Mimosa pudica) plant extract as the main ingredients in edible coatings on the quality and shelf life of apples. A Completely Randomized Design (CRD) was employed with four treatments: no coating (P0), coating with 2% extract (P1), 4% extract (P2), and 6% extract (P3). The results revealed that the combination of these extracts contained antimicrobial compounds such as dodecanal, octane, 1,1-diethoxy-, squalene, and methyl stearate, which effectively inhibited spoilage. The P3 treatment (6% extract) proved the most effective in maintaining apple quality, as indicated by stable weight, firmness, and sustained sugar and vitamin C content during storage.
