The purpose of this study was to examine and analyze the factors influencing household energy expenditures in Thailand. With sample group of 57,600 households. The findings reveal that the majority of the sample population is male, with an average age of 54.31 years, and most are married. The majority have an education level of primary or secondary school and are primarily Own-account worker (without employee), Private company employee or engaged in other job. In terms of social characteristics, the average household size is 2.71 people. Most residences are located in the Central, Northeastern, and Northern regions with similar proportions, followed by the Southern region and Bangkok, respectively. Most type of dwelling in detached houses, with materials of construction being cement or brick, followed by half concrete and wood. Regarding tenure, almost own dwelling and land, with an average of 2.88 rooms per household. Electricity is available in all households, with an average of 2.30 vehicles per household and an average of 22 electrical appliances per household. Regarding economic characteristics, most respondents have government/state enterprise welfare and receive benefits from the government programs. The majority have never borrow money from government funds. The average communication services of respondents amount to 788.46 THB, while the average household debt stands at 4,760.74 THB. At a significance level of 0.05, the factors influencing household energy expenditures in Thailand include gender, education level, marital status, job, household size, residential region, type of dwelling, material of construction, tenure, number of rooms, number of vehicles, number of electrical appliances, welfare of medical services, receive benefits from the government programs, borrow money from government funds, communication services, and household debt. However, age does not affect household energy expenditures in Thailand. The results of multiple linear regression analysis indicate that six quantitative independent variables—communication services, number of household electrical appliances, number of vehicles in the household, household debt, number of rooms, and household size—explain variations in household energy expenditures, with an Adjusted R Square value of 0.561.

This cooperative education report presents a project for developing a Distributed Control System (DCS) for boilers in a sugar factory. The objective is to enhance the control system for boilers 1-8 to operate cohesively within the DCS framework provided by ABB, utilizing the ABB Ability™ System 800xA software. The overall functionality of the system involves creating a control program that begins with the utilization of bagasse, a byproduct from the sugar extraction process, as fuel for the boiler. The program manages various operations of the boiler, including the intake of air into the combustion chamber, the internal functioning of the boiler, and the treatment of flue gases before their release into the atmosphere. The project encompasses the development of the DCS program, the design and creation of HMI display graphics, the study and design of the boiler control system, the documentation of the project, and the control processes utilizing the ABB Ability™ System 800xA software, culminating in the operational outcomes.
