Abstract

White oyster mushroom is a type of food that is easily damaged (a highly perishable food). This study aimed to determine the rate of change in texture, color, volatile compounds, and amino acid composition in white oyster mushrooms during storage at various temperatures and CO2 concentrations. The research design used was a Factorial Complete Randomized Design (FCRD), with a storage temperature treatment (A) consisting of three levels, namely A1 (10 ± 2 °C), A2 (20 ± 2 °C), A3 (30 ± 2 °C) and treatment of adding CO2 gas (B) consisting of four levels, namely B0 (control), B1 (20%), B2 (30%), and B3 (40%). Tukey HSD carried out the treatment that was significantly different at a 5% level. The results showed that the order of the quality decline reaction of the white oyster mushrooms was order one. The best treatment for storing the white oyster mushrooms with a MAP method of PE packaging was the addition of 30% CO2 at a storage temperature of 10 °C. The major volatile compounds in fresh white oyster mushrooms were 3-Octanone (44.54%), 3-Octanol (23.24%), 3-Heptanone, 6-methyl- (10.26%), whereas after 10 days of storage were 3-Octanone (35.05%), 3-Octanol (25.89%), and 5-Ethyl-3methylhept-1-en-4-ol (8.45 ppm). The major amino acid composition in fresh white oyster mushrooms was glutamate, aspartate, and lysine, whereas after 10 days of storage were glutamate, lysine, and aspartate.Keywords : Amoni acid, White oyster mushroom

Abstract

White oyster mushroom (Pleurotus ostreatus) is a perishable food ingredient. The purpose of this study was to determine the total plate count in white oyster mushrooms during storage with MAP. This study consisted of two stages of the process, the first stage was sample preparation and the second stage was the analysis of the total plate count and the determination of the reaction order. The results showed that the TPC in white oyster mushrooms stored in MAP with PE plastic and the addition of 30% CO2, storage temperature of 10oC on day 0 to 10 days of storage was increase of 3.34 – 11.49 log cfu/mg. White oyster mushrooms stored for 24 hours (day 1) experienced a significant increase in TPC of 6.32 log cfu/mg. Changes in TPC of white oyster mushrooms during storage under MAP conditions at 100C tended to increase.

Abstract

Transportation of oil palm Fresh Fruit Bunches (FFB) from the plantation to the harvest collection point (TPH) must be done as quickly as possible. This is due to an increase in free fatty acids after the FFB is harvested. Some of the obstacles found were the FFB transportation equipment which was not yet capable of reaching the fruit in the garden easily and the transportation time which was quite long due to the uneven road conditions. With technological advances and the rapid development of innovation, the discovery of track model wheelbarrows that use a driving engine means that further studies are needed to determine the effectiveness of these transport machines. In this research, we will compare wheelbarrows without engines and wheelbarrows with track models, there are 3 (three) treatments given, namely on flat roads, bumpy roads and damaged roads. Researchers search for and collect data on transport capacity, transport load, transport speed and transport costs. The results of this research show that carrying capacity and road conditions have a effect on travel time and speed. This is due to the ability/power of the machine which is quite large and stable in transporting fruit. and, other results from this research show that the use of motorized wheelbarrows can reduce transportation costs because the transportation speed increases so that the travel time is shorter.

Abstract

White oyster mushroom is one type of mushroom that is popular in Indonesia. This study aims to determine the rate of change in water content and weight loss of white oyster mushrooms during storage. This study used a Completely Randomized Factorial Design with two treatments with 3 replications. The first treatment (A) was the difference in storage temperature (10, 20 and 30oC) and the second factor (B) was the difference in CO2 gas concentration (control, 20, 30 and 40%). Parameters observed were water content and weight loss. The results showed that the water content before storage was 90.47%, after storage at a temperature of 10oC for 10 days increased in the range 92.71% - 93.81%. The temperature 20oC for 8 days increased in the range 93.54% - 94.02%, while at 30oC for 3 days it increased 94.36%. White oyster mushroom weight before storage ranged from 100.00 g - 110.00 g after storage at 10oC for 10 days weight loss in the range of 2.04% - 2.1%. Storage temperature of 20oC for 8 days decreased in the range of 2.37% - 2.90%, while at 30oC for 3 days it experienced 4.01%. The Q10 value of the highest water content change was obtained at the addition of 30% CO2 with a value of 3.00. The Q10 value of the highest weight loss change was obtained at the addition of 0% CO2 with a value of 1.18.

Abstract

Water hyacinth (Eichhornia crassipes) is a weed that lives in water and has a high growth rate. It has the ability to increase evapotranspiration (evaporation and loss of water through plant leaves), reduce the amount of light entering the water, resulting in a decrease in the level of oxygen solubility in water, disrupt water traffic, and increase habitat for disease vectors. aquatic environment. A solution is needed to overcome this problem, one of which is by composting. In order for composting to take place faster, Starbo AFE and Probio FM activators are used which will provide good quality. this study aims to determine the effect of various activators on the nutrient content of water hyacinth compost, and to determine the best combination of activators on the nutrient content of water hyacinth compost. This research method uses one replication with three treatments (K1 K2 and K3 using Starbo AFE and Probio FM, and K0 without Starbo AFE and Probio FM). This study was conducted in two stages, namely the composting stage. The composting process was carried out for 30 days. Checks are carried out every 5 days in the form of turning and physical observation. After the composting process is complete, nutrient measurements are carried out. Characterization is carried out to determine the levels of C-Organic, N, P, K, and Aroma. The results of this study showed that Starbo AFE and Probio FM are effective against C-Organic, N and K levels and aroma in accordance with SNI.
