Abstract

The cereal production especially rice has increased sharply in Indonesia. The irrigation development program implemented by the government has become an important rote in the production process. However, expansion of irrigated paddy lands significantly influence the hydrological regime in its basin. A set of basic indicator for assessing the hydrological implication of the development in a river basin was proposed.

Abstract

Study of time allocation in rotational irrigation system was carried out in Cikesik Irrigation Scheme, Cirebon, West Java during the dry season of 1989/1990. The study aims to estimate lime loss factor in water allocation and distribution, and to demonstrate the use of time loss factor for improvement of water allocation and distribution by rotational method. Results of the study show that during the water flowing in the canal systems, there is time toss beside hydraulics and volumetric losses. All these types of losses will significantly influence on opportunity of offtake time by each tertiary blocks, and therefore, its should be used together as considerations for allocating and distributing irrigation water. By using the improved method, equity in water distribution as the main objective of the rotational water distribution will be improved.

Abstract

In this study some characteristics of iron-protein complex in soybean tempe were investigated. Tempe was prepared by fermenting dehulled cooked soybeans at 30°C for 0; 24; 48; 72 and 96 hours, respectively. Tempe protein was extracted using Tris-maleate butfer at pH 6.5 and the extract was dialyzed in cellulose tube MM. 12,000. The residue was fractionated using Sepharose 6B/CI-6B gel filtration. The protein and iron distribution in those fractions and their molecular weight were determined. Results showed that fermentation increasing the number of protein fractions. The molecular weight of protein fractions was in the range of 5.000 - 70,000 daltons. Iron was distributed in all fraction measured. The percentage of protein and iron in fractions with molecular weight > 70,000 daltons decreased with longer fermentation time. Some of the small molecular weight of protein fractions failed to pass the cellulose membrane

Abstract

Tahu dibuat dengan peragaman penggumpal yait u kalsium klorida asam sitrat dan laru dengan konsentrasi masing-rnasing antara 1,5 - 3 persen, 1 - 2 persen dan untuk laru dengan jumlah 750 ml - 2250 ml pada perbandingan air dengan kedele 8:1; 10;1;12:1 dan 14:1 untuk mengetahui pengaruh konsentrasi penggumpal dan air terhadap tekstur tahunya. Hasil penelitian menunjukkan bahwa konsentrasi penggumpal kalsium klorida dan laru bersama dengan peragaman proporsi air tidak memberikan pengaruh terhadap tekstur tahu ditunjukkan dengan determinasi masing-masing 0,29 dan 0,23. Kombinasi penggumpal asam sitrat dan air ternyata mempengaruhi tekstur tahu dengan determinasi sebesar 0,82 dengan persamaan regresi T (tekstur) = - 1,64 + 0.39 A (air) + 0.66 P (penggumpal). Persamaan tersebut dapat dijadikan pegangan dalam pembuatan tahu uniuk mendapatkan hasil dengan tekstur yang diinginkan tanpa rnerubah kondisi pengolahan lainnya.
