Abstract

Has carried out activities to the community in the form of the development of the printing press in the village briquettes Jatireo Gunungpati Kodia subdistrict in Semarang. The background of this activity is to address the process of making briquettes at the time of printing, where the results obtained are not crowded so long the flame is not as expected. To overcome these problems have created a tool that is used to press briquettes load prior to release of the molding tool. The results showed no difference in the thickness of the pressed briquettes are pressed. The thickness of the briquettes without using the press is 1 cm and 0.5 cm using a press. In addition, test results obtained by burning briquettes burning rate of the skin and fro in the range of 0.03 to 0.04 g/s. This result is consistent with the type of biomass briquettes from other types such as wood, leaves, etc. with 0.03 combustion rate g/s. The color of the flame indicated when laboratory testing is reddish yellow and the smoke does not cause itching when on the skin.

Abstract

The purpose of this study was to evaluate the effectivity of the leaf garbage composting process were given three different kinds of activators.The material composed are chopped leaf garbage and goat manure in the ratio of 3: 2, and make in three activators treatments. There are activators of orange peel waste, vegetable waste and EM4 product as a comparison. Compost is harvested after the composting process lasted for 21 days. The variables measured include (1) changes in daily temperature, pH, humidity compost during the composting process, (2) quality parameters such as physical parameters (texture, colour, odor, and depreciation), and chemical parameters (water content, pH, and C/N ratio). All of data were analyzed descriptively. The changes of daily temperature, pH, and humidity on EM4 compost activator treatment showed highest depreciation (39.3%) followed by compost with vegetable Mol and waste orange peel ( 31.6% and 29.8%), while the graphs of pH and humidity appear constant during this process. Accordance with the percentage of the depreciation, C/N ratio of the compost with EM4 activator showed the lowest (14.73). Generally, parameters of texture, colour and odor no different, as well as the water content and pH. This study concludes that composting treatment successfully and produce compost according to the criteria of SNI standard Number 19-7030-2004.
