Air tanah sangat potensial untuk mengairi tanaman pangan terutama palawija di lahan tadah hujan. Salah satu cara pemanfaatan air tanah tersebut dengan membuat sumur pantek. Hal ini memungkinkan karena kedalaman air tanah relatif dangkal (10-15 m dari permukaan tanah). Pengembangan air tanah tersebut akan berdaya guna apabila manfaat yang diperoleh cukup besar dibandingkan dengan biaya yang dikeluarkan. Frekuensi pemberian air tiap 14 hari tidak berpengaruh nyata terhadap hasil kedelai dan jagung di Sukamandi (Subang), Haurgeulis (Indramayu) dan Adipala (Cilacap) dibandingkan pemberian air tiap 7 maupun 10 hari. Penyaluran air yang berasal dari pompa menggunakan slang plastik untuk mengurangi kehilangan air selama penyaluran sehingga menghemat bahan bakar pompa. Besar biaya untuk pengoperasian pompa rata-rata Rp 240.000,- dan Rp 265.000,- masing-masing untuk kedelai dan jagung sedangkan keuntungan bersih rata-rata budidaya kedelai dan jagung masing-masing Rp 374.000,-/ha dan Rp 321.000,-/ha

Method and instrument for measuring local water content inside food
1996
Thorvaldsson, K. | Skjoldebrand, C.
A new method of measuring local water content inside food during heat processing has been evaluated. The method uses a fibre optic NIR-Instrument. The evaluation was mainly based on investigations of the influence of structure and temperature. The instrument was found to be very sensitive to both the structure and the temperature of the sample. The dependence on the temperature of the sample can be incorporated into the calibration and is thereby not an impediment to the measurements. The structural dependence makes quantitative measurements at different places in the sample difficult for inhomogeneous materials. However, measurements of dynamic changes in the water content in one spot work well for both homogenous and inhomogeneous materials and are probably the best application of the instrument. By using two or more optic fibres, the diffusion of water can also be measured.
