Abstract

Abstrak. Kabupaten Aceh Selatan memiliki rerata curah hujan bulanan yang sangat tinggi sebesar 281,4 mm/bulan, sehingga memiliki potensi aliran permukaan yang tinggi. Ketersediaan curah hujan yang melimpah pada musim hujan belum dimanfaatkan secara optimal pada musim kemarau. Air hujan sebagian akan menjadi aliran permukaan sehingga tidak bisa dimanfaatkan tanaman secara efektif. Dampak dari terjadinya aliran permukaan yang tinggi akan menyebabkan hilang humus tanah sehingga terjadinya penurunan kesuburan lahan. Desain teknis sistem pemanenan air hujan yang efektif untuk konservasi air tanah dan memenuhi kebutuhan air tanaman pala telah dapat dibuat dengan rincian sebagai berikut: Sistem pemanenan air hujan pada penelitian ini menggunakan rorak yang dilengkapi saluran peresapan. Tata letak rorak dan saluran peresapan menyesuaikan dengan kontur lahan. Dimensi rorak ditentukan sesuai dengan debit aliran permukaan, yaitu kedalaman maksimal 30 cm dengan lebar 40 cm danpanjang 100 cm. Setiap rorak disertai saluran peresapan dari sisi kiri dan kanan dengan panjang 100 cm, dalam 10 cm dan lebar 20 cm.Abstract. South Aceh district has a very high average monthly rainfall of 281.4 mm/month, so it has a high potential of runoff. The availability of abundant rainfall during the rainy season has not been used optimally in dry season. A part of rainfall would become surface flow so that the plant cannot use it effectively. The impact of high surface flow will cause in loss of soil humus which leads to the decline of soil fertility. Technical design of rainwater harvesting systems which is effective for soil and groundwater conservation and for fulfil water needs from nutmeg crops could be constructed as : rainwater harvesting systems by using rorak equipped with infiltration channels. Rorak layout and channel infiltration should be adjusted to the contour of the land. Rorak dimensions are determined by the discharge of surface flow, which has the maximum depth of 30 cm, width of 40 cm and length of 100 cm. Each rorak is built with infiltration channels on the left and right side with lengt hand depth of 10 cm and width of 20 cm.

AbstractOn non-irrigated farming land, soil water content was difficult to be maintained in field capacity condition. Zero runoff system (ZROS) attempted to utilize runoff and to convert it to backup soil water content using permeation structures. The objectives of this research was to analyze the changing of soil water content before and after ZROS had been applied and to calculate ZROS effectivity towards infiltrating rainfall. In this research, permeation structures in the research field was usingsilt pit and collector canal. The changing of soil water content before and after ZROS application was calculated by water balance model in therooting zone. The simulation result showed that after ZROS had been applied, the decreasing of soil water content in research field were ranging from -0.001 to -0.009 m3/m3, while before ZROS had been appliedit were ranging from -0.01 to -0.024 m3/m3. Besides that, ZROS also capable to increase soil water content in research field for 25.57%. The increasing of this soil water content was caused by ZROS ability that canhold and infiltrate 51.04% from total rainfall occurredeffectively.Keywords: permeation structure, runoff, soil water content, water balance model, zero runoff systemAbstrakPada lahan non irigasi, kadar air tanah sulit dipertahankan pada kondisi kapasitas lapang dan sangat tergantung pada curah hujan.
