           EFFECTS ON COMPRESSION IGNITION ENGINE PERFORMANCE

    • Authors: KANOK-ON RODJANAKID
      Pages: 1 - 10
      Abstract: This research attempted to study the biodiesel production reaction by transesterification of crude palm kernel oil and refined palm kernel oil. From the experiment found that methyl esters synthesized from crude palm kernel oil were lower than methyl esters synthesized from refined palm kernel oil under the same conditions due to the oil's purity and different acidity. Butanol was used to produce diesohol at a low mixing ratio in this experiment. Physical properties, homogeneity were then tested after six months of storage. Conduct the test by D90Bu5B5(RPKO) mixed well without stratification after six months of storage. From the experiment biodiesel produced has a maximum productivity equal to 90.8%. Biodiesel was then used as an ingredient in the D90Bu5B5(RPKO). Then testing D90Bu5B5(RPKO) for physics properties and performance in the engine. From the experiment found that the D90Bu5B5(RPKO) had similar physical properties to diesel fuel except the flash point is lower than high-speed diesel fuel. The result of the performance found that D90Bu5B5 had slightly less torque and brake power than standard diesel fuel with a higher fuel consumption rate than diesel fuel

  • EFFECT OF BIOCHAR AS AMENDMENT OF POTTING SOIL ON GROWTH AND YIELD OF
           THREE LEAF VEGETABLES GROWN IN RAISED GARDEN BEDS

    • Authors: Thanachai Chalatchaliao
      Pages: 46 - 55
      Abstract: Biochar, a material derived from pyrolysis process under limited- oxygen condition, is light weight and can be a source of plant nutrition which mostly made from agricultural waste. The objectives of this study were to characterize biochars that made form tree branches, bamboo, durian shell and biochar mixed (MB) from these biochars at rates of 50, 30 and 20% by weight, respectively. Furthermore, to study effect of biochar combined with commercial potting soil (CP) and cow manure (CM) at different rates on growth and yield of three green vegetables such as Bok Choy, Pak Chai and Chinese kale planted in raised beds. Each of experimental design was randomized complete block (RCB) with 5 treatments and 48 plants or replications such as 1) 100%CP, 2) 80%CP + 20%MB, 3) 50%CP + 50%MB, 4) 40%CP + 30%MB + 30%CM and 5) 50%CP + 50%CM. Growth and yield of vegetables were collected 45 days after transplant as well as potting soil properties were analyzed after harvest. Results showed that all biochars were alkaline have pH at range of 8.06 – 9.87. Cation exchange capacity (CEC)of biochars varied with pH. Durian biochar contains highest concentrations of available P and exchangeable K which were 2,374 and 32,627 mg kg-1, respectively. Results of potting soil mixed from MB, CP, and CM showed that MB and CM promote growth vegetables compared to 100%CP, especially potting soil mixed from 40%CP + 30%MB + 30%CM significantly enhanced growth and yield all vegetables. For example, Bok Choy, Pak Chai gained approximately twice of fresh weight and promoted photosynthesis of Chinese kale noticeable from leaf greenness. Adding of MB lead pH and CEC of potting soil mix after harvest but has not effect on EC values also increase nitrogen use efficiency. In conclusion, this study supports the feasibility of adding mixed biochar up to a maximum of 50% in the potting soil that has no effect on growth and yield of the green vegetables.

  • THE DESIGN AND CONSTRUCTION OF AUTOMATIC 3 SPEED SOLAR PANEL CLEANING
           MACHINE CONTROLLED BY MICROCONTROLLER

    • Authors: Chaiporn Addoddorn
      Pages: 56 - 69
      Abstract: This paper presents the design and construction of automated 3 speed level solar panel cleaning machine controlled by microcontroller with pulse widths modulation at 30, 60 and 100 percent to clean solar panels instead of humans. It consists of a charging circuit 2 drive motors, 1 brush motor, 1 solenoid valve, indicator light and Arduino Mega 2560 microcontroller circuit. This solar panel cleaning machine can move in 2 directions are longitudinal walk of the panel forward and backward with 2 DC motors and 2 cut-off limit switches, the unit can polish the solar panel by 1 DC motor connected to the brush set. There is a solenoid valve for cleaning water. There is a wireless light that shows the working status of the machine and shows the battery level in 3 levels are full, middle and low. The microcontroller will order the drive motor and brush motor to work. The solenoid valve will work with an indicator light. From testing, it was found that on dry areas the solar panel cleaning machine can move forward and backward as needed. In wet areas, the solar panel cleaning machine can move but there will be a slight interruption of the unit because the drive wheels are so slippery that they can't carry the machine to move easily. The brush and brush motor test shows that if the brush is attached, the brush motor speed will decrease due to the motor being loaded. In the actual test drive, the speed of the brush motor will decrease according to the frictional area and efficiency test of the automatic solar panel cleaning machine for unclean panels will be 62.06% efficiency and for clean panels will be 95% efficiency, making it safe and saves a lot of human labor.

To achieve a balance of utilization and allow effective management in addition to the use of energy storage technology to improve stability and reduce the problem of energy instability from renewable energy sources. The technology also reduces congestion in power distribution systems during times of high-power demand. It can also reduce the time and cost of construction of transmission lines. Although today the technology of energy storage systems has been developed and advanced much from the original. But some technologies are still in the research and development stage and not worth the investment. In the future, if such technology is developed and widely used, it will provide a more stable overview of the system and lower operating costs. In this academic article,
      we will discuss different types of energy storage technologies. Implementation and benefits the growing demand and today's technology.
