PERENCANAAN LONG STORAGE JETIS KEC BLORA KAB BLORA
ABSTRACT: Floods are natural
disasters that regularly occur in DAS Lusi during the rainy season. Reduced
water catchment areas in the upstream area of the river is one of the causes of
increased flood discharge in river Lusi. Attempts to reduce it is to plan long
storage system, a building that utilizes water as a resevoir riverwith weir
building in the downstream.Long storage will be built on the upstream of the
Lusi, located at Jetis, Kecamatan Blora, Kabupaten Blora. The purpose of the
construction of long storage Jetis is a flood control system and as a resevoir
for the surrounding areas. From the result of rainfall data in Blora, Jiken,
Jepon, Bogorejo and Tempuran station, return period of 25 years Q25 = 242.059
m3 / sec are used to analyze the capacity of the river and weir stability.
While the discharge is used in analyzing the resevoir using a debit andalan
based formula FJ Mock with large long storage bin is 42 liters / sec.Plan
development time required was 12 weeks with a total budget of Rp.
12,852,198,000.00. (Twelve billion eight hundred and fifty-two million one
hundred ninety eight thousand rupiah).
