Abstract

Some studies have been done on utilizing biomass from agriculture such as the leather and shell of rubber (Hevea brasiliensis) were not used optimally in Indonesia as an alternative energy which developed by making biobriquet to achieved the higher energy that could be used in the combustion process. In this study, the biobriquet was made of the leather and the shell of rubber by comparisson of the leather and shell were: 0%: 91%; 45.5%: 45.5%; 55%: 36%; 64%: 27%; 91%: 0%.Glyserin 9% for each percentage of biobriquet was used as adhesive material and the drying temperature of 110 C. This study aims to investigate the characteristics of biobriquet combustion which made of the leather and shell of rubber. The results shows that the biobriquet combustion process which made of 64% rubber leather and 27% rubber shell has a calorific value of 5313,923 Kal/gr. In 20 seconds of initial ignition, the combustion process shows the improvement such as increased concentrations of the flammable leather, bluish red fire.

Abstract

Security is the most important and primary thing in human life. It is generally known that security systems in the form of CCTV cameras and security guards have not been effective in providing a deterrent effect to criminals in carrying out their actions. So it takes a way to deal with this, the author created a prototype of an anti-crime security system using open CV on python based on a microcontroller. From the test results after conducting several experimental scenarios on the prototype that was created, it can function normally. The system created is able to identify or recognize facial samples at a distance of about 1.5 meters, with a minimum light intensity of 407 lux. The prototype is able to track the presence of target movements and can follow target movements from an angle of 0o-180o vertically and from an angle of 00-60o vertically, and can shoot targets in a stationary position within 5 seconds.
