PLTM GIRIMUKTI 1 (2x4,2MW) dan GIRIMUKTI 2 (2x1.5MW) LAPORAN HIDROLOGI

BAB 1PENDAHULUAN1.1. LATAR BELAKANGAnalisis hidrologi merupakan hal yang sangat penting diperlukan dalam perencanaan suatu PLTM (Pembangkit Listrik Tenaga Mini Hidro) yang merupakan salah satu pendukung dalam menilai kehandalan suatu PLTM. Analisis hidrologi untuk PLTM biasanya berupa analisis ketersediaan air yang ada pada suatu sungai yang akan disadap sebagai parameter penting dalam unsur pembangkitan. Adapun lingkup kajian adalah analisis ketersediaan air dan analisis debit banjir.

1.2. MAKSUD DAN TUJUANMaksud dari penulisan laporan ini ialah untuk mengkaji kondisi hidrologi DAS Cibuni dalam menunjang kegiatan Perencanaan PLTM Girimukti I dan Girimukti II.Tujuan dari studi ini adalah untuk menginformasikan tentang ketersediaan air dan kondisi debit banjir yang ada pada DAS Cibuni bagi keperluan Perencanaan PLTM Girimukti 1 dan Girimukti 2.BAB 2KONDISI HIDROMETEOROLOGISejalan dengan meningginya elevasi, umumnya curah hujan bertambah, diikuti dengan menurunnya lama penyinaran matahari dan temperatur udara. Berhubung Stasiun Klimatologi yang berdekatan dengan daerah lokasi tidak ada, maka data dimabil dari Badan Meteorologi dan Geofisika Bandung yang berada pada koordinat 0605500 Lintang selatan, 10703600 Bujur Timur dan berada pada elevasi 791 meter. Ketersediaan data meteorologi yang digunakan adalah dari tahun 1996 samapi dengan tahun 2005.2.1 TEMPERATURTemperatur udara bulanan rata-rata yang terjadi, umumnya berkisar antara 22.8 C 23.7 C. Temperatur bulanan minimum terjadi di bulan Juli sedangkan temperatur bulanan maksimum terjadi di bulan Mei. Temperatur udara pada musim hujan dan kemarau tidak menunjukkan variasi yang menonjol. Variasi temperatur udara musiman menunjukkan kaitan yang erat dengan variasi curah hujan bulanan.

2.3 LAMA PENYINARAN MATAHARI Penyinaran matahari bulanan rata-rata yang terjadi, umumnya berkisar antara 47.4 % hingga 77.2 %. Penyinaran matahari bulanan terbesar terjadi di bulan Agustus sedangkan yang terendah terjadi di bulan Januari.

2.4 KELEMBABAN RELATIFKelembaban relatif bulanan rata-rata yang terjadi, berkisar antara 70.6 % hingga 81.2 %. Kelembaban bulanan rata-rata yang rendah terjadi pada bulan Agustus sedangkan tertinggi pada bulan April.

2.5 CURAH HUJANData curah hujan, dari hasil pengumpulan data diperoleh 5 (lima) stasiun terdekat dengan lokasi studi. Kelima stasiun curah hujan tersebut adalah Stasiun Rancabali, Stasiun Rancasuni, Stasiun Cibuni, Stasiun Citambur dan Stasiun Sinumbra.

Pengaruh monson terlihat dengan adanya pola curah hujan musiman, dimana musim kemarau yang terjadi pada DAS Cibuni berlangsung pada bulan Juni sampai dengan Oktober dan musim penghujan pada periode November hingga Mei. Peta lokasi stasiun curah hujan yang digunakan dalam analisa hidrologi ditampilkan pada Gambar 5. Tabel 1 Stasiun curah hujan yang digunakan dalam analisis

2.6 DAEAH ALIRAN SUNGAIPLTM Girimukti I dan II berada pada Daerah Aliran Sungai Cibuni dengan sungai utama (main river) adalah Sungai Cibuni. Adapun anak-anak sungai (tributary) yang masuk pada sungai utama pada masing masing lokasi ditabulasikan pada Tabel 2. Tabel 2 Sungai utama dan anak sungai pada lokasi kajian

BAB 3ANALISIS KETERSEDIAAN AIR3.1 ANALISIS EVAPOTRANSPIRASIEvapotranspirasi merupakan faktor penting dalam memprediksi debit dari data curah hujan dan klimatologi. Alasannya adalah karena evapotranspirasi ini memberikan nilai yang besar untuk terjadinya debit dari suatu daerah pengaliran sungai. Evapotranspirasi diartikan sebagai kehilangan air dari lahan dan permukaan air dari suatu daerah pengaliran sungai akibat kombinasi proses evaporasi dan transpirasi.

Evapotranspirasi potensial adalah evapotranspirasi yang mungkin terjadi pada kondisi air yang tersedia berlebihan. Faktor penting yang mempengaruhi evapotranspirasi potensial adalah tersedianya air yang cukup banyak. Jika jumlah air selalu tersedia secara berlebihan dari yang diperlukan oleh tanaman selama proses transpirasi, maka jumlah air yang ditranspirasikan akan relatif lebih besar dibandingkan apabila tersedianya air di bawah keperluan. Adapun hasil perhitungan evapotranspirasi potensial ditabulasikan pada Tabel 3 dan Gambar 6. Tabel 3 Hasil Perhitungan Evaporasi Potential PLTM Girimukti

3.2 ANALISIS KETERSEIDAAN AIRAnalisis perilaku hidroklimatologi dilakukan berdasarkan statistik data historis, antara lain rata-rata, simpangan baku, minimum, maksimum, dan koefisien variasi. Angka koefisien variasi menyatakan seberapa besar variabilitas debit. Semakin besar variabilitas debit aliran sungai berarti sungai tersebut memerlukan perhatian khusus, yaitu misalnya pembangunan tampungan air (waduk).

Analisis ketersediaan air, atau analisis potensi air dilakukan dengan menggunakan berbagai alternatif data dasar sebagai berikut:

a Berdasarkan data runtut-waktu (time-series) dari data yang ada (historis), bilamana data tersebut tersedia.

b Jika tidak tersedia data debit, atau jika ternyata data debit yang ada hanya mencakup kurang dari lima tahun, maka perkiraan potensi sumber daya air dilakukan berdasarkan data curah hujan, iklim dan kondisi DPS dengan menggunakan model hujan-aliran (rainfall-runoff model).

Dari kedua cara tersebut diatas, maka akan diperoleh data debit aliran bulanan yang cukup panjang sehingga dapat dilakukan analisis dengan tahapan sebagai berikut :

Konversi satuan debit aliran sungai dari satuan meter-kubik/detik menjadi satuan milimeter/hari, sehingga dapat diterapkan pada sembarang titik di DPS, misalnya di muara sungai, batas kabupaten, dan lokasi bendung atau pengambilan air.

Analisis statistik dari data debit tersebut, juga analisis durasi dan analisis frekuensi sehingga akan diperoleh debit aliran dengan :

tingkat keandalan Q80%, atau boleh gagal sekali dalam lima tahun, untuk memasok irigasi; dan

tingkat keandalan Q90%, atau boleh gagal sekali dalam 10 tahun, untuk memasok air bersih rumah-tangga, perkotaan dan industri.

Analisis Ketersediaan Air

Ketersediaan air dalam pengertian sumberdaya air pada dasarnya terdiri atas tiga jenis, yaitu air hujan, air permukaan, dan air tanah. Air hujan pada umumnya hanya berkontribusi untuk mengurangi kebutuhan air irigasi yaitu dalam bentuk hujan efektif, meskipun pada beberapa daerah air hujan yang ditampung dengan baik juga menjadi sumber air yang cukup berarti untuk keperluan rumah tangga.

Sumber air yang berpotensi besar untuk dimanfaatkan adalah sumber air permukaan dalam bentuk air di sungai, saluran, danau, dan tampungan lainnya. Penggunaan air tanah yang kenyataannya sangat membantu pemenuhan kebutuhan air baku maupun air irigasi pada daerah yang sulit mendapatkan air permukaan harus dijaga agar pengambilannya tetap berada di bawah debit aman (safe yield).

Ketersediaan air dapat didefinisikan dalam berbagai cara. Dalam hal lokasi ketersediaan air dapat berlaku pada suatu titik, misalnya pada suatu lokasi pos duga air, bendung tempat pengambilan air irigasi, dan sebagainya dimana satuan yang kerap digunakan adalah berupa nilai debit aliran dalam meter kubik atau liter perdetik. Banyaknya air yang tersedia dapat juga dinyatakan berlaku dalam suatu areal tertentu, misalnya pada suatu wilayah sungai, daerah pengaliran sungai, daerah irigasi, dan sebagainya, dimana satuan yang kerap digunakan adalah berupa banyaknya air yang tersedia pada satu satuan waktu misalnya juta meter kubik per tahun atau milimeter per hari.

Analisis ketersediaan air menghasilkan perkiraan ketersediaan air di suatu wilayah sungai atau suatu sistem tata air, secara spasial maupun dalam waktu. Analisis ini pada dasarnya terdiri atas langkah-langkah sebagai berikut:

1)analisis data debit aliran;

2)analisis data hujan dan iklim;

3)pengisian data debit yang kosong serta memperpanjang data debit runtut waktu; dan

4)analisis frekuensi mengenai debit aliran rendah.

Metode yang digunakan pada analisis ketersediaan air adalah Metode Mock. Adapun rekapitulasi hasil analisis ditabulasikan pada Tabel 4 dan Tabel 5.Tabel 4Rekapitulasi hasil perhitungan ketersediaan air PLTM Girimukti I (A = 161.75 km2)
