Abstract
Waduk Tugu merupakan waduk yang terletak di desa
Nglinggis Kecamatan Tugu Kabupaten Trenggalek. Secara
geografis terletak pada koordinat 08 02 27 LS dan 111 35 07
BT. Pembangunan waduk Tugu diharapkan mampu menyediakan
air irigasi untuk sawah penduduk seluas 1200 Ha dan bertujuan
untuk mengembangkan areal irigasi serta meningkatkan intensitas
tanam dari areal irigasi yang telah ada. Selain sektor pertanian,
waduk Tugu diharapkan sebagai penyedia air baku di bagian hilir
sungai Keser, mengembangkan bidang perikanan serta
meningkatkan sekor pariwisata.
Seiring dengan pembangunan waduk, maka diperlukan suatu
pedoman pengoperasian air di waduk agar dapat memenuhi
berbagai kebutuhan yang direncanakan. Maka dari itu, perlu
dilakukan studi optimasi waduk Tugu.
Dalam studi ini, optimasi dilakukan untuk kebutuhan air baku,
kebutuhan air irigasi dan potensi PLTA. Untuk mengatasi
keterbatasan air, kebutuhan air baku dianggap konstan. Kebutuhan
air irgasi dihitung dengan beberapa alternatif jadwal tanam yang
berbeda. Tiap-tiap alternatif dihitung water balance air waduk.
Output dari water balance ini yaitu mengetahui kondisi air
tampungan waduk dan mengatahui jadwal tanam yang paling
efektif dan efisien. Sehingga waduk Tugu dapat digunakan secara
optimal.ii
Dari hasil analisa yang telah dilakukan, didapatkan
kesimpulan yaitu besar kebutuhan air baku sebesar 11,88
liter/detik, waduk Tugu dapat mengairi sawah seluas 1000 Ha
dengan pola tanam padi-palawija-palawija dan jadwal tanam
dimulai pada Desember II atau Desember III, dan potensi PLTA
sebesar 127,34 kW

Tugu reservoir that located in the Nglinggis village ,
Trenggalek. Geographically located at coordinates 08 02 27
LS and 111 35 07 BT. Tugu reservoir serves to irrigate an
area of 1200 hectares and developing irrigation areas and
increase the intensity of farming in the existing area. Besides
agriculture,Tugu reservoirs as a provider for water demand in
downstream Keser river, defeloping fisheries sector and improve
the tourism sector
Along with the construction of reservoirs, it would require a
manual operation of water in the reservoir in order to meet the
various needs planned. Therefore, it is necessary to study the
optimization of Tugu reservoir.
In this study, the optimization is done on the water demand
requirements, irrigation and hydropower potential. To overcome
the limitations of water, water demand was constant. Irrigation
water requirement is calculated with several different alternatives
planting schedule. Each alternative is calculated water balance
reservoir water. The output for the water balance is to determine
the condition of the water catchment reservoir and planting
schedules for the most effective and efficient. So the reservoir can
be used optimally.
Based on the analysis that has been done, it was concluded that
large raw water needs of 11.88 liters / sec, Tugu reservoir caniv
irrigate an area of 1000 hectares with cropping pattern of padipalawija-palawija and most effective planting schedule began in
December II, and the potential for hydropower amounted to 127.34
kW
