A common way to increase the efficiency of distillation of solar energy is by cooling the cover glass. The method of cooling glass that is widely studied is the spray method. Spray method still has a weakness that is not theÂ entire surface of the glass can be wetted cooling water. The water reservoir method allows wettage of the entire surface of the cover glass so that the cooling process can be better. This study aims to increase the efficiency of the distillation of solarÂ energy water by cooling the cover glass using a water reservoirs method. Parameters varied during this experimental stage are: the cooling water mass rate. Parameters measured were: (1) absorber temperature, (2) cover glass temperature, (3) cooling water temperature, (4) input water temperature, (5) ambient air temperature, (6) distilled water, 7) solar energy coming and (8) data recording time. The conclusions of this study were: the largest distillate water yield obtained was 3.26 liter / (hari.m2) with an average efficiency of 41.0%. Distilled water yield and best efficiency are obtained at cooling water rate of 7.1 liter / hour. The temperature difference between the absorber and the largest glass is 11.4Â°CKeywords: cooling, water distillation, solar energy, water reservoirs

The current problem of solar energy water distillation is in its low efficiency. Low efficiency is caused by inefficient water evaporation processes. Increasing the efficiency of water evaporation is done by controlling the rate of water entering into the absorber. The commonly used mechanical control system still has weaknesses such as the instability of the water entering the absorber. This causes less effective evaporation of water so that the resulting distillation efficiency is not optimal. The water rate input system for distillation in this study is based on a simple microcontroller. The microcontroller-based input water rate control system allows the rate of input water with a small but continuous flow rate so that the water evaporation process can be more effective. This study aims to improve the efficiency of solar energy water distillation by increasing the efficiency of the water evaporation process through controlling the flow rate of water inlet. The research was carried out by the experimental method. The parameters varied were: the rate of input water which was 0.3 l / hour, 0.5 l / hour and 1.2 l / hour. Parameters measured in this study were: (1) temperature of absorber, (2) temperature of the cover glass , (3) temperature of cooling water, (4) input water temperature, (5) ambient air temperature, (6) distilled water results, (7) solar energy coming in and (8) time of recording data. The results showed that the production of distillation water using microcontroller-based water rate control was a maximum of 523% compared to the model without water rate control at a water flow rate of 0.3 liters / hour, with distillation efficiency of 66%. From the results of this study it can also be concluded that microcontroller based water flow rate controller is more stable than mechanical water flow controller, especially in small flow

The wood-furniture drying process in the industry using wood fuel is deemed inefficient, wasteful, takes a long time, is unsafe, impractical, and not environmentally friendly. Furthermore, the process of drying fertilizer blocks with the sun, apart from requiring a large area of land, also cannot be carried out in the rainy season. This service is carried out in two industrial partners, namely CV Nuansa Kayu Bekas in Sragen and PT Wira Cahya Pratama in Klaten. This service aims to increase understanding of an effective drying machine for the drying process of wood furniture and block-fertilizer in the industry by using a vapour compression cycle. In addition, to increase productivity and profits in the industry. The training venues are conducted in the industries of the two partners. Activities in this service include training on drying machines and assistance in the manufacture, operation and maintenance of effective dryers, especially for the wood-furniture and fertilizer-block industries. The implementation of the service has been going well and smoothly. The outputs produced are activity videos, publications in Suara Merdeka newspaper, Jogja Daily and the Sanata Dharma University website, service articles published in service journals, and Partner satisfaction surveys.
