SUMMARYMAK. Overview of water management system of agricultural land in the port village of swamp of Lebak in the Pemulutan subdistrict of South Sumatra. (Tutored by Prof. Dr. IR. Hasbi, M.Si).Practice this field aims to study and understand the systems of water management conducted by padi farmers at rawa lebak in increasing agricultural production in the village Port in the Sub-District of Pemulutan Regency Ogan Ilir. The practice field is funded on 1 may until July 12, 2015, by observing the plantings to irrigate farm land directly in the rice field farmer groups Source works.Agricultural land resource group of farmers work the land is a swamp of lebak shallow puddle with a height of less than 50 cm. High standing water on rice field other than land sourced from rain water is also affected by the overflow of the water stream ogan. Water management system in rice field farmer groups land Resource Work in rainy season rely solely on rain water as a source of water for the rice plant.During the dry season farmers incorporated in farmers Group Source Works already apply the irrigation pump. Pompanisasi irrigation i.e. utilize diesel-powered water pumps as a source of energy to channel water to the rice field mapped through pipelines paralon preinstalled at the side of the map in rice fields complete with tap water. There are two types of pump irrigation i.e. large scale irrigation pumps to irrigate rice fields on a large scale of approximately 25 Ha and small-scale irrigation pumps to irrigate some map rice only.Sarana irigasi pompa yang dibutuhkan untuk mengairi lahan sawah terdiri dari : 1 unit mesin pompa air bertenaga diesel dengan tegangan 12 Volt dan mampu menghasilkan energi sebesar 3,2 kW menggunakan bahan bakar solar. Bak penampungan air berukuran 5 x 5 m. Instalasi pipa dengan dua jenis tipe pipa yaitu pipa UV atau paralon ukuran 6 inchi dan pipa besi ukuran 6 inchi.Permasalahan yang ditemukan dalam praktik lapangan ini meliputi belum adanya jaringan drainase di lahan persawahan sehingga sangat sulit untuk mengendalikan tinggi muka air lahan. Bangunan irigasi yang tidak lengkap sehingga petani mengalami kesulitan dalam melakukan pengelolaan air lahan di musim hujan. Pintu air yang menghubungkan sungai ogan dengan saluran air irigasi tidak ada yang aktif atau tidak dapat digunakan dengan optimal. Pintu air tidak dapat menahan laju kehilangan air di lahan persawahan saat sungai surut. Pada jaringan irigasi pompa terdapat masalah pada pipa penghisap air yang digunakan yaitu pipa sering mengalami keanginan sehingga dapat menghambat proses pengairan pada lahan sawah.
