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

Mayonnaise contains a substantial amount of fat and water. Therefore, it is easily degraded during storage. Reducing fat and moisture content in mayonnaise could extend its shelf life. It can be done by replacing the egg yolk to octenyl succinic anhydride (OSA)-corn starch and then forming it as a premixed block using a binding agent. The research objective was to obtain technology for low-fat mayonnaise making by OSA-cornstarch and corn starch addition but still acceptable by consumers based on its physicochemical and sensory characteristics. The low fat premixed mayonnaise was made by mixing the egg yolks and/or OSA-corn starch, corn starch, mustard, sugar, salt, and xanthan gum. A completely randomized research design was used with three levels of OSA-corn starch (0, 25, and 50%) to replace egg yolk and its combination with corn starch as a binder agent at 43 and 50%. The parameters analyzed on the premixed mayonnaise blocks included moisture and fat content, water absorption index, and water solubility. In contrast, parameters for constituted mayonnaise were moisture content, viscosity, and hedonic sensory analysis by 25 semi-trained panelists. The constituting step of the mayonnaise was the further addition of water, oil, and lime juice before serving. The data were analyzed with ANOVA. The results showed that OSA-corn starch and corn starch addition could reduce the fat content of premixed mayonnaise by 41.7% which was obtained from 50% OSA-corn starch and addition of 43% corn starch. The resulted mayonnaise was slightly liked by the semi-trained panelists (scored 3).

Abstract

Abstract: The investigation of aquatic and dry land weeds as fibers resources for paper making was carried out. The selected fiber resources of aquatic weeds were water hyacinth (Eicchornia crassipes) and water chestnuts (Eleocharis dulcis), and bladygrass (Imperata cylindrica) as the selected dry land weed. Research was designed as a factorial completely randomized design with two factors. The first factor was fibers origin (Eicchornia crassipes, Imperata cylindrica, Eleocharis dulcis) and the second factor was the fibers pulp slurry concentrations (30%, 50%, and 70% v/v). Results showed that the fibers origin and fibers pulp slurry concentration had significant effect on the tensile strength, mass density, water absorption, and frictional resistance of paper. The interaction between the fibers origin and fibers pulp slurry concentration had significant effect on tensile strength, frictional resistance, water absorption; but had no significant effect on mass density of paper. The paper that was made of 70% (v/v) of water hyacinth fiber pulp slurry showed the best characteristics with the tensile strength of 3.65 kgf mm-1, mass density of 0.87 g cm-3, water absorption of 0.235 g cm-2, and frictional resistance of 0.028 g cm-2.Keywords: water hyacinth, water chestnuts, bladygrass, paper.Abstrak (Indonesian): Penelitian tentang sumber serat dari gulma air dan lahan kering untuk pengolahan kertas telah dilakukan.

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.

Ariyani GP, Hower H, Tamrin T, Pratama F. 2022. DSSC’s electrical performance from dye of bungur leaf (lagerstroemis speciosa) with varied dye concentration. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 105-112. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Dye Sensitized Solar Cell (DSSC) can convert solar energy into electrical energy using organic matter (dye) as a sensitizer, but it necessary to innovate on dye so that resulting efficiency is optimal. The purpose of this research was to determine the electrical performance of Dye Sensitized Solar Cell (DSSC) with varied dye concentrations of Bungur Leaf Extract (Lagerstroemis speciosa). The research methods included the preparation of the DSSC structure, the preparation and assembly of the DSSC, and DSSC analysis. The chlorophyll content in the leaves of Bungur was calculated based on the absorbance characteristics at wavelengths of 649 nm and 665 nm. The results of the measurement of chlorophyll levels in Bungur leaves were directly proportional to the addition of concentration. The higher the solvent concentration, the more chlorophyll would bind dye. At concentrations of 2% to 8%, the efficiency increased with the values respectively 0.0018%, 0.0047%, 0.0054%, and 0.0114%. Afterwards, at the highest concentration of 10%, the efficiency decreased by 0.0050%. The chlorophyll content in the leaf dye affected the performance of DSSC at a certain concentration limit which was due to the accumulation of dye molecules in the TiO2 pores.

Abstract

Snakehead fish is one of the freshwater products that has potential in South Sumatra. Utilization of snakehead fish as a side dish and diversification product is for typical Palembang food processing. Most of these preparations used meat as a raw material, leaving waste scales, skin and bones which had the potential to be used as raw materials for collagen. One of the stages of collagen production was soaking in NaOH. The aim of this research was to examine the chemical properties of scales, skin and bones of snakehead fish after soaking in NaOH. The soaking process was carried out in 0.05M NaOH for 6 hours and the water was changed every 2 hours with a ratio of waste to NaOH solution of 1:10. The parameters analyzed included water content, ash content and protein. The results showed the proportion of scales, skin and bones of snakehead fish respectively of 6% scales, 5.7% skin and 4.20% bones. Proximate analysis tests showed levels in snakehead fish scales of 55.67%, skin by 81.15% and bones by 50.80%. The average value of ash content was in snakehead fish scales of 48.14%, skin by 9.27% and bones by 55.42%. The average value of protein content was in snakehead fish scales by 29.60%, skin by 67.59% and bones by 23.66%.
