PERANCANGAN DAN UJI KINERJA SPRINKLER SEDERHANA

Abstract

Abstract
Sprinkler irrigation is a way of watering plants by spraying water into the air and
falling on the ground to resemble rain. Sprinklers are generally applied to commodities with
high economic value, so sprinkler prices are also quite expensive. Sprinklers currently
circulating in the market are sold in various models, some can rotate 180 to 360 degrees with
different beam distances. The purpose of this research is to design and manufacture a simple
sprinkler prototype and examine the performance of the sprinkler prototype that is made. The
method used is the experimental method and the descriptive analysis method, which focuses
on performance testing using the prototype sprinkler that is made. This study used several
components of the equipment such as 6 sprinklers , water pumps and piping networks in a
land area of 18 m × 12 m. The variables observed in the study included: water discharge,
pump rotation (rpm), uniformity coefficient (CU), jet distance, use of pump fuel. The results
of this study indicate that the application of sprinkler irrigation water uses 6 sprinkler
prototypes that were made and a Korobe WR 20X water pump, with a time of 2 minutes, 6
sprinklers can release 154.12 L/minute of water with an average pump speed of 3,758. 33
RPM and spent as much as 45 ml/minute of fuel. The farthest distance of the sprinkler beam
is 3.5 meters.
