Abstract

Optimalisasi pemanfaatan sumber daya air pada jaringan irigasi memiliki manfaat dapat memenuhi kebutuhan air irigasi secara lebih efektif. Jaringan irigasi Semirejo memiliki luas sekitar 402,3 ha memilik 2 intake di Bendung Semirejo, terletak di Kabupaten Pati Jawa Tengah. Penelitian ini bertujuan untuk memberikan alternatif pola tanam, ketersediaan air, dan menghitung Benefit hasil tanam sehingga dapat merencanakan pola tanam yang memiliki keuntungan yang tinggi. Penelitian ini menggunakan data sekunder dan diolah menggunakan Solver Excel. Hasil dari analisis kebutuhan air eksisting mendapatkan nilai kebutuhan tertinggi pada masa awal tanam. Terdapat kekurangan air dengan faktor K 26% pada bulan oktober I sebesar 212,75 l/s Semirejo Kanan. Pada Semirejo Kiri mengalami kekurangan air 190,8 l/s periode oktober I dengan faktor K 28%. Alternatif terpilih dimulai pada bulan desember, untuk Semirejo Kiri dengan jumlah keuntungan bersih sebesar Rp15,093,774,785 dengan pola tanam per Masa Tanam I & II padi (19,78 ha), ubi kayu (100 ha), tebu (79,5 ha), MT III padi (100 ha), jagung (29,6 ha), tebu (79,5 ha) dan Semirejo Kanan sebesar Rp15,239,061,980 dengan pola tanam per MT I & II padi (19,78 ha), ubi kayu (100 ha), tebu (73,42 ha), MT III padi (50 ha), jagung (69,78 ha), tebu (73,42 ha). Benefit setelah dilakukan optimasi didapatkan Semirejo kanan meningkat 46,9 % dan 60,5% untuk alternatif kiri.

The Semirejo dam has significant water availability potential from the Gembong reservoir and Tamansari pond, which can enhance farmers' profits if the crop yield in the highland areas is optimal. This research aims to provide alternative planting patterns, assess water availability, and calculate the Benefit Cost Ratio (BCR) of crop yields to plan for high-profit planting strategies. This study utilizes secondary data, processed using Excel Solver and Cropwat 8.0. The analysis results indicate that the alternative planting pattern for Semirejo Kiri yields Rp10,948,937,330, while Semirejo Kanan yields Rp12,475,761,063. There is a water deficit of 67.28 l/s in October I and 142.86 l/s in October II for Semirejo Kanan. For Semirejo Kiri, the water deficit is 45.56 l/s in October I and 123.4 l/s in October II. However, after changing the planting patterns and area adjustments, water needs can be met with a factor of K > 1. The water balance projection for 2035 shows a surplus for Semirejo Kanan of 1,047.4 l/s in MT I, 4,137.7 l/s in MT II, and 2,724.8 l/s in MT III, while Semirejo Kiri has a surplus of 854.8 l/s in MT I, 4,354.1 l/s in MT II, and 3,235.1 l/s in MT III. The existing Benefit Cost Ratio for Kanan is 4.7 and for Kiri is 2.8; after optimization, the value for Semirejo Kanan increases to 5.7, a rise of 21.4%, and for Kiri, it increases to 3.2, an increase of 15.3%.
