Abstract

TPS is a temporary shelter of garbage before it is transported or disposed of to landfill. In order for TPS to accommodate garbage, it is necessary to know the volume of garbage to be served. This study aims to; firstly knowing the occurrence of household waste produced in the village of Jempong Baru, the second conducts an evaluation of the feasibility of TPS capacity to temporarily accommodate the waste produced based on the results of the study. The method used is descriptive method by conducting garbage survey based on SNI-19-3964-1994 and TPS capacity evaluation based on PERMEN PU RI No. 03/PRT/M/2013. From the results of the study obtained the emergence of household waste produced by the community in the village of Jempong Baru 6183 kg / day or 41907 liters / day equal to 41.9 m3 / day. Organic waste 3779 kg / day, plastic waste 572.5 kg / day, other non-organic waste 1775 kg / day. Then the results of measurement and evaluation of existing TPS with a capacity of 32 m3 with a waste ritasi one rate per day. So the existing TPS capacity is not enough to accommodate the volume of waste produced per day as much as 41.9 m3. The TPS capacity should be greater than the volume of waste produced. The results of this study are very useful to make improvements to the waste management system in Mataram city and especially in the village of Jempong Baru which is efficient and effective.

Abstract

Post-harvest handling of grain before being ground or stored for a long time is drying or reducing water content.  To dry the grain is more effective by using a mechanical dryer. In this study, grain drying was carried out using a continuous vertical dryer by varying the grain mass to determine the effect of grain mass variation on the grain drying time.  Mass variations observed were 10 kg, 20 kg, 30 kg, 40 kg, 50 kg, 60 kg, with an air temperature of 50°C and an air velocity of 7 m/s. The result showed that the more grain mass the lower the drying rate. However, the drying time was longer, and the efficiency was higher. At the 10 kg, the fastest drying time was 75 minutes.  Whereas at the 60 kg,  the maximum drying time was 150 minutes.  The highest efficiency of 8.78, occured at a mass of 60 kg and the lowest efficiencywas 1.6%  occured at a mass of 10 kg.
