Abstract

The abundant peat water in Buluh Cina Village, Siak Hulu Subdistrict, Kampar is a natural potential that can be used for cooking and bathing purposes by processing peat water into clean water that is suitable for consumption. The purpose of this service activity is to treat peat water into clean water. The method used in this service activity is using coagulant and filtration technology. The optimal filtration and coagulant media used for peat water treatment consists of biosand filters with two media namely pumice and quartz sand. The dedication results reduce turbidity and color of peat water and reduce organic content, so that peat water is processed into clean drinking water. The lowest pH value before filtering is equal to 5.93 and the highest pH is found before filtering which is 6.23. This means that before filtering peat water is weak acidic. The lowest sample results after filtration with a slow sand filter that is equal to 6.42 and the highest pH after filtration of 7.5, which means that water is weakly basic. A good pH limit for water is 6.5 to 8.5 so this service proves that slow sand filters are considered effective enough to optimize water pH. Total dissolved solids (TDS) is one of the parameters for determining water quality, TDS shows the amount of solute solids in water. The result of peat water TDS is that the lowest TDS value before filtration is 46 mg / L and the highest TDS is found before filtering which is 49 mg/L. The lowest sample results after filtration with slow sand filter is 49 mg / L and the highest TDS after filtering is 83 mg/L.

Abstract

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
