The study aimed to investigate appropriate formula for drinking yoghurt production. The conditions were ratio of yoghurt : concentrated rambutan juice at 100 : 0 90 : 10 85: 20 and 75: 25 the effect of concentrated rambutan juice on physical and chemical and microbiological lactic acid bacteria survival appropriate proportion of syrup and lactic acid bacteria survival during storage of drinking yoghurt from rambutan juice. It was found that proportion of concentrated rambutan juice had no effect in color (L* a*) of the yoghurt (p>0.05) but its impact to b* and viscosity were significant (p≤0.05) they increased with the increased proportion of the concentrated rambutan juice. Yoghurt with 15% concentrated rambutan juice had 88% survival rate of lactic acid bacteria after stimulated digestive system. The results showed that optimal production formula of drinking yoghurt from concentrated rambutan juice and syrup were 90:10 Z(yoghurt: concentrated rambutan juice; 85:15) : syrup) Drinking yoghurt stored in the refrigerator at 4±1oC for 15 day was evaluated and found that LAB survival numbers were 9.90 log CFU/mL.

The objective of this study were 1) to develop the gas detector unit for installation on Drone and 2) to test the operational sensitivity of the developed device. The development steps included designing complying the electrical circuit testing the electrical system and online connecting system. Besides the operational sensitivity of the developed device was tested comparing the Gas Alert Micro 5 IR the reference gas detector device both in the laboratory and the field site. The results showed that the developed gas detector could detect carbon dioxide carbon monoxide and methane and displayed the results via Line notification every minute. Additionally carbon dioxide detection by MG-811 sensor gave the results similar to the reference device by 95 percent of significant level with the average amount of detected carbon dioxide in the laboratory and the field site were 700-915 ppm and 138-399 ppm respectively. However the measured results of carbon monoxide and methane from the develop device were relatively different to the reference device. Further study on carbon monoxide sensor and methane sensor calibration are recommended.
