This paper presents a CMOS voltage reference design which is widely used in electronic circuits both analog and digital circuits. In the conventional a CMOS voltage reference circuit design composed of several MOS transistors and complicated circuits the output voltage cannot be adjusted to any levels. Therefore in this paper proposed the CMOS voltage reference circuit design technique based on a new current combination circuit which it was reduced number of MOS transistors and the proposed circuit is able to operate without complex startup circuit. The performance of the proposed circuit is confirmed through PSPICE simulation results the circuit can be operated with supply voltage varies from 2V to 4V the output voltage reference is about 231 2mV at wide temperature range of -80 to 120 it has very low temperature coefficient of about 37.65 ppm/ and a total power dissipation of 7.37 W

Silk was one of economic goods that provided high revenue for agriculturists. Due to changing weather however there were some problems and limitations of silkworm breeding. For instance too hot and humid weather caused mold infection and made the silkworm easily get infected. On the other hand too less humidity might lead to dry mulberry leaves. In addition the agriculturists had no records of the silkworm breeding. This research realized these current obstacles and aimed to develop an embedded Android application system to control electrical system and temperature in a silkworm house. The operation was divided into 3 parts consisting of direct control via control board of the silkworm house control via wireless Bluetooth on the application SMS delivery system to warn distant users. The results of this study provided the electrical control system and temperature in the imitated silkworm house. It could automatically control the internal temperature and retrieve data of control equipments via the Android application system and Bluetooth for near distance about 20 meters and far distance by sending SMS. The system also measured the actual temperature and humidity from SHT11 Module. The temperature could be fixed between 24-30 Celsius while the humidity could be defined between 60-90% by applying ventilators lights and jet sprayer

This study was aimed to investigate experimental study of the parameters affecting the amount of tubular ice. Significant studied parameters were inlet water temperature. Thickness tendency was increasingly according to time. The thickness of the tubular ice varies with the square root of time according to the theory. At the beginning of the process thickness increased quite fast and decelerated at the end of the production process. The inlet water temperature affected to thickness of tubular ice as the ratio of inlet water temperature to thickness was 0.41 degrees Celsius per millimeter. Thus inlet water temperature affected to thickness of tubular ice according to theoretically results with 342% 43% and 8% error value between ice thickness and production time for 0-10 minutes 11-20 minutes and 21-36 minutes respectively

The effect of azimuth and pot color on the variation of pot surface and growing media temperature was studied. Four pot colors that including with black brown silver and white color were used. The growing media comprised with soil : rice husk : coconut dust at 1:1:1 ratio. From the result of this study the azimuth and pot color effected the variation of pot surface temperature. The azimuth effected the variation of pot surface temperature at 8.00 10.00 14.00 and 16.00. At 8.00 and 10.00 pot surface temperature in east direction was the highest while at 14.00 and 16.00 pot surface temperature in west direction was the highest. Whereas pot color effected the variation of pot surface temperature at 8.00 10.00 and 14.00 with black color was the color that had the highest 33.3 39.1 and 46.4 C respectively. On the other hand the white color was the color that could the highest reduces the pot surface temperature when compared with the temperature of black pot color which were 4.6 3.9 and 4.3 C lower than that in a black pot respectively. Not only the effect on the variation of pot surface temperature pot color was also affected on the variation of growing media. Pot color effected the variation of growing media temperature during 8.00 to 18.00. When compare the growing media temperature among the pot color with that in black pot color which was the highest temperature white color pot was the highest efficiency to reduce the growing media temperature especially at 10.00 and 12.00. White pot color could reduce the growing media temperature about 5 C follow by silver color pot was about 3 C while the growing media temperature in brown color pot was not difference with that in black color pot

The results of this research . The result is a Dan Kwian clay. In the study were formulated clay all 3 formulas contain ingredients such different kaolin borax feldspar and dolomite by using theoretical triangle (Trixial Blend) to find the ingredients and the results obtained in the experiment can make clay . Clay qualification in variety usage such as well forming less wrinkle non-crack strong and colourful as requirement. Every recipe is Dan Kwian is the main ingredient for proper implementation of the Community Dan Kwian. The coating experimental in this research there were 2 glazing formulas burn in the temperature of 1000OC-1050 OC in the gas Kiln and wood kiln and the coating colour experiment with the mixed of oxide and stain by using the Line Blend theory. The colour value random from the experiment resulted which were 2 glazing formulas differed which was beautiful and the differed proper character usage. The study found that Can bring the knowledge and methods of the experiment to use in the production Dan kwian actually. As a further development of the local pottery. To create a new form and add value to the product. Can generate more revenue and resulting in a much stronger community.
