Supercapacitor electrodes from rubber wood saw dust (RWSD) have been fabricated using experiment method to study the ball milling variation time on performance of the supercapacitor cells. The carbon electrodes were prepared with time variation of 20, 40, and 80 hours and thickness of 0.2 mm. Carbon electrodes were carbonized at 600oC and followed by physical activation method in CO2 gas atmosphere on the constant temperature of 900o C, and chemical activation was performed by KOH as an activating agent. Densities of the electrodes were 0.849 g/cm3 , 0.892 g/cm3 , 0.982 g/cm3 respectively. XRD measurement showed the peaks of carbon electrodes at 2θ of 24.091o and 44.473o which represented the presence of carbon materials with their crystal orientation of (002) and (100). SEM micrograph on magnification of 1000X showed that the pore distribution of the carbon electrodes dominant on macropores. This study found that the effects of increasing of ball milling time influenced the electrochemical properties of supercapacitor electrodes fro m RWSD.

The potential of the laundry sector, the entrepreneur community / UKM Laundry in Tampan District, which has very potential business potential. This clearly saves the huge potential of the Laundry / UKM business sector. The clothes drying system, which is carried out through the traditional drying method, has long been practised by Laundry UKM entrepreneurs. In particular, the clothes drying activity has long been a source of livelihood for the Laundry UKM community in Panam District. However, in general, the process of drying clothes through a drying method that relies solely on sunlight is not optimal. The process of drying clothes by laundry entrepreneurs in the Tampan District is still done traditionally, namely drying in the sun. This process takes a long time, it takes 2 to 4 days to dry clothes and it also depends on the presence of sunlight. The drying machine is designed to utilize heat from burning coconut shell waste which functions as a heat collector. So that the drying process can take place quickly, at any time and without depending on the sun. Control of the drying temperature is done by opening and closing the air ducts in the dryer. This dryer consists of a solar collector, biomass burning furnace, and drying room (box). The drying room functions as a place for clothes to be dried. The flow of heat from burning coconut shell waste to the drying chamber. The result of drying clothes is better than traditional drying. The drying technology based on coconut shell waste to dry clothes will be applied in the Laundry UKM community in Tampan District, Pekanbaru which is the livelihood of some UKM in Tampan District, Pekanbaru City
