This thesis presents the design and construction of an experiments of the power flow in the power systems. For the operating system of the power flow in the power systems. Comprise with the real power Reactive power Voltage in the power system. To guide the planning and operation of power systems. The results of the experiment to calculate the pressure at various points in the Power loss of system. As well as finding solutions to problems. Occurring in the system such as under voltage or short circuit in the system. This is the basic of stability analysis of power system operation and planning

This study was experimental study that had the propose to investigate the possibility of using sludge from wastewater treatment of milk production in case study of Friesland Campina Fresh (Thailand) Co Ltd. This study to investigate suitable ratio in making briquette between sludge and banana peel in ratio 95 : 5 75 : 25 50 : 50 25 : 75 and 5 : 95 by weights and analysis of compressed char were Moisture content Ash content Volatile matters Fixed carbon and Calorific value. The result of this study we found that sludge mixed with banana peel at the ratio of 25 : 75 had Moisture content 9.7 percent Ash content 15.8 percent Volatile matters 61.8 percent Fixed carbon 9.7 percent and Colorific mean 4195 kcal per kg. It can also be used briquette fuel substitutes of firewood in order to conserve the forest resources.

Abstract The objective is to analyze Klong Prem Prachakorn water quality and its water management. A total of 10 parameters include pH water temperature turbidity dissolved oxygen (DO) biological oxygen demand (BOD) chemical oxygen demand (COD) suspended solid (SS) total dissolve solid (TDS) and coliform bacteria were measured. Water samples were taken from 3 sampling points along the length of the canal between Bang Khen train station intersection and Wat Samian Nari intersection with a total distance of 1.3 kilometers. Samplings were done weekly for 5 weeks started from 12th December 2013 to 15th January 2014. The results from weekly monitoring of Klong Prem Prachakorn’s water quality show that the values of each parameters being monitored are within the range of the surface water quality standards. Howeverthe reporting values may show weekly fluctuation which may be resulting from relating environmental factors such as changing temperature the canal’s water volume and level (may results from the operation of the floodgate by the Department of Drainage and Sewerage). Nevertheless the values show that the canal water is clean for surface water according to type 4 water quality and can be used inindustrial sector. This study on Klong Prem Prachakorn’s environmental condition has provided a piece of knowledge that was appliedfor environmental problems’ corrective concepts and guidelines. Furthermore knowledge and information gathered in this study together with the use of a Geographical Information System (GIS) can be applied for ecological conservation studies of the areas. This study contributes to an existing knowledge and understanding of Klong Prem Prachakorn’s water quality problems and can be used to support water quality improvement campaign

The objective of this research is to preparation of dye powder from natural dyes. The conditions of preparation of dye powder and properties of natural dye powder were studied. The natural dyes were used in this research containing of Lac Ebony heart wood Sappan heart wood Turmeric and dried Butterfly pea. The natural dyes powder were prepared by three methods; oven drying salt adsorption and salting out. The natural dyes powder were dyed on silk fabric and then characterized by colour strength (K/S) washing fastness and light fastness. The results showed that the dye powder from dried Butterfly pea could not be prepared by dye powder preparation used in this research because of the dye power was not stable. The dyes powder from Lac Ebony heart wood Sappan heart wood and Turmeric were prepared by all three methods. The oven drying and salting out methods showed higher K/S than salt adsorption method. And the K/S of dyes powder from oven drying and salting out methods were not significant. In the oven drying method showed good K/S on silk fabric dyed from the turmeric dye powder. And salting out method showed good K/S on silk fabrics dyed from Lac Ebony heart wood and Sappan heart wood dyes powder. The different dye powder preparation methods did not effect on the colour appearance. The washing fastness of dyed silk fabric from different preparation methods were not significant. The dye powder of Lac Ebony heart wood Sappan heart wood showed good light fastness and the Turmeric dye powder showed poor light fastness on silk fabric.

Water Hyacinth Yarns and Their Transformed Materials Dyeing Machine for Developing Small and Medium-Sized Enterprises was a research project what an aim for producing a prototype dyeing machine. The machine was used at the small enterprise in Nakhon Prathom province. The dyeing machine was contributed by stainless steel. The outer dimension was 100 centimeters in height 130 centimeters in length and 90 centi-meters in width. The inner structure contains with perforate stainless steel drum. It had diameter as 80 centimeters with 90 centimeters length. The container capacity was 27 liters for the raw material as 10 kg of the dry Water Hyacinth Yarns or 5 kg of the dry Water Hyacinth roots. The machine was running test for reactive dyeing process at 80oC for 30 minutes. The machine was achieved for reduce time operation as 5 times and gas consumption as 2.38 times. The break-even point was 1.09 year and B/C as 2.22. Moreover it can solve the fuzzy yarns problem and the volatile smoke during the tradition dyeing. The knowledge was transferred to the stakeholders at the target area as “Chumchonjaksanpaktobchawha Bann klongnokkratum” enterprise in Nakhon Pra thom province. They were satisfied in this benefit in good to very good level.
