White bread has a short shelf life thus the loses its desired charcteracteristics upon storage and its also subject to spoilage by fungi. To avoid this spoilage and increase shelf life the addition of different levels of acidulants (calcium propionate acetic acid and sorbic acid at 0.1 0.2 and 0.3%) were evaluated for their quality characteristics contributing with acidulants as well as their microbial shelf life during 12 days of storage. In addition the mathematical model (GAB and BET) were applied to study the storage condition of bread. From the experiment it was found that bread with calcium propionate addition had the highest specific volume and springiness followed by bread with acetic acid and sorbic acid adding. On the other hand bread contained sorbic acid had the highest density hardness chewiness and color values (L* a*b*) followed by acetic acid and calcium propionate addition in order. Bread contained calcium propionate had the longest shelf life (12 days) followed by bread with acetic acid (8 days) and sorbic acid (6 days) adding respectively. The increase in acidulants levels result in an increase of bread shelf life. From the sorption isotherm curves bread contained 0.3% calcium propionate had the highest monolayer moisture content indicating that it was the most effective against microbrial spoilage of white bread studied.

This research study analyzes the problem of waste water from the burning of palm trees which are used as fuel for power generation of palm ash. It is used to ferment biogas as a fuel for power generation where a large amount of wastewater from the gas digester is completed. The wastewater is then pumped out of the gas digester. Biological in large quantities Therefore to study the analysis of wastewater to find a method for designing a wastewater treatment system from high voltage systems from the corona discharge principle when adding ozone it is necessary to analyze the chemical effects of the wastewater according to the standard values of the Department of Industrial Works.

This research aimed to: 1) develop an elderly quality of life promotion model for self-reliance through community product processing: 2) develop community product processing to promote income of the elderly and: 3) promote coexistence activities among the elderly.

The objective of this paper is to study: 1) Impact of change in TFRS for PAEs during 2014 – 2020 for annual reports of Agriculture Business and Foods from SET; 2) Level of earnings quality and profitability ratio of Agriculture Business and Foods from SET during 2014 - 2020; and 3) Factors affecting on level of earnings quality and profitability ratio of Agriculture Business and Foods from SET during 2014 – 2020. Data was collected from 35 firms by using Consolidated Financial Statement Annual Report by using Modified Jones Model. This research results used SPSS software for analyses Descriptive Statistics and Multiple Regression Analysis. The results showed that: 1) Almost CEO has chosen to reduce the impact of change in TFRS and report only necessary impact. They showed the only materiality of professional judgement by adjusted in the impact of unappropriated retained earnings at the beginning periods for adjusted separate entry in Change in Financial Position Statement. This result also showed that almost items during 2019 and 2020 have more impact from change in TFRS 15 TFRS 7 TFRS 9 and TAS 32; and 2) Before TFRS for PAEs have impact (published) It showed the effects of fluctuation on Discretionary Accrual (DAC). It trends to decrease in Discretionary Accrual after TFRS for PAEs have published for many years. However it showed that level of earnings quality by using DAC between 2014 – 2020 was not significant at α = 0.05 or level of significant at 95%. While the consolidated financial statements during 2014 – 2017 Agriculture Business and Foods have increasing in ROA continuously. However after situations of impact from changing TFRS in 2019 – 2020 and situation of Corona Virus 2019 have effect on the fluctuation of ROA decreasingly.; and 3) the effect of change in TFRS for PAEs and type of ownership structures and group of businesses have no impact on level of earnings quality at significant level (α =0.05). However the effect of change in TFRS for PAEs has negative impact on return on assets (ROA) at significant level (α <0.01). While type of ownership structure group of businesses and firm size have positive impact on ROA at significant level (α < 0.05)
