Abstract

The process of cultivating white oyster needles is quite easy and supported by the raw materials used, which are easy to find at affordable prices. However, inappropriate raw materials and media composition, as well as an inappropriate baglog position will affect the growth of mycelium so that the results in white oyster mushroom cultivation are less than optimal. This study aims to determine the mixture of planting media and the variation of baglog position on the optimal growth of white oyster mushroom mycelium. This research method uses an experimental form with the type of research used is descriptive quantitative. The research design in this study was a factorial randomized block design. The results of this study were the concentration with 25% corn flour was the treatment with the best mycelium length, namely the final mycelium length average of 17.45 cm. The treatment with 35% corn flour was the treatment with the best mycelium thickness. The position of placing the baglog for growing white oyster mushroom was not significantly different from the growth of mycelium, this was because at the time of laying the baglog the position of the baglog was spaced and not piled up.

Abstract

Discarded coffee grounds are unfortunate, considering they have potential as a planting medium because they contain compounds that can support plant growth. Likewise, husk charcoal provides benefits because it has a porosity which can bind water and has the nutrients needed by pakcoy plants. This study aims to analyze the utilization of coffee grounds and husk charcoal as a planting medium for the growth of pakcoy plants. This study used a Completely Randomized Design (RAL) with six treatments and three replications. The treatments applied are control (M0) 100% soil, (M1) 40% soil + 10% coffee grounds + 50% husk charcoal, (M2) 40% soil + 20% coffee grounds + 40% husk charcoal, (M3) 40% soil + 30% coffee grounds + 30% husk charcoal, (M4) 40% soil + 40% coffee grounds + 20% husk charcoal, (M5) 40% soil + 50% coffee grounds + 10% husk charcoal. The changes observed were plant growth (plant height, number of leaves, length of roots, total fresh weight of the plant, dry weight and chlorophyll levels. The best planting medium in the M1 treatment is a combination of 40% soil + 10% coffee grounds, and +50% husk charcoal. From the study results, it can be concluded that coffee grounds and husk charcoal can be used as a planting medium for the growth of pakcoy plants

Abstract

The sugar industry, in addition to producing cane sugar, also produces molasses which is the by-product of the sugar bleaching process. This waste still contains a lot of sugar ± 56%. and organic acids. The purpose of this study was to use molasses as a substrate for A. xylinum to be developed as an indicator of banana freshness. Cellulose produced from molasses substrate can be used as material for placing indicators. Freshness indicator has a working principle by observing changes in fruit freshness that are detected due to changes in pH in atmospheric conditions that are increasingly acidic as a result of metabolic activity. The freshness indicator of bananas from cellulose from 20% molasses substrate has different results of changes in the color of the freshness indicator. The method used in this research to apply the BTB compound to the cellulose sheet produced from molasses to be applied to 3 types of bananas (ambon, kepok and raja). Indicators affixed to plantains reach the indicator color change faster than ambon and kepok. Changes in this indicator are in line with physical and chemical changes in bananas which indicate a decrease in freshness. Both in terms of physical and chemical degradation.
