Abstract

Talas belitung merupakan umbi yang berpotensi sebagai salah satu sumber alternatif pangan lokal. Pengolahan umbi talas menjadi tepung dapat memperluas pemanfaatannya menjadi berbagai jenis produk olahan pangan. Tujuan penelitian ini yaitu mengetahui karakteristik sifat fisiko-kimia dan fungsional tepung talas. Penelitian menggunakan desain eksperimen sederhana dengan tiga perlakuan berbeda yaitu kontrol (P0), pengukusan 30 menit (P1), dan fermentasi spontan 72 jam (P2). Setiap perlakuan dilakukan pengujian sebanyak 2 kali ulangan untuk melihat perubahan karakteristik fisiko-kimia dan fungsional tepung yang dihasilkan. Hasil penelitian menunjukkan bahwa sifat fisik tepung dengan warna paling cerah (L=78,10) pada perlakuan fermentasi, sedangkan rendemen tertinggi pada kontrol (22,82%) dan densitas tertinggi pada pengukusan (0,48 g/ml). Sifat kimia pada perlakuan fermentasi memiliki beberapa nilai tertinggi dibandingkan perlakuan lain yaitu kadar protein (5,73%), lemak (1,42%), serat pangan total (4,14%), pati resisten (16,10%) dan abu (1,63%). Sedangkan kadar karbohidrat tertinggi pada kontrol (81,80%) dan kadar air terendah pada pengukusan (9,38%). Sifat fungsional pada perlakuan pengukusan memiliki nilai tertinggi dibandingkan perlakuan lain yaitu pada swelling power (360,64%) dan water holding capacity (213,75%), sedangkan nilai water holding capacity tertinggi pada perlakuan fermentasi (105,45%).  Perbedaan metode penepungan akan mempengaruhi karakteristik fisiko-kimia dan fungsional tepung yang dihasilkan. Perlakuan fermentasi spontan memiliki lebih banyak keunggulan dibandingkan perlakuan lain terutama pada sifat fisik dan kimia.

Abstract

Sustainable agriculture system is also based on the approach that through methods focusing on environmental conservation and resource efficiency — food and agricultural resources could suffice for the present generation and continue to be able to meet this need of future generations. The study investigates the water footprint of orange cultivation and photovoltaic solar-driven irrigation as one of the approaches to assuring energy-water security in a water-scarce region such as Latakia Governorate, Syria. Since water has become so difficult to access, and the cost of energy is still high, one of the challenges for most agricultural operators who would like to produce oranges continues to be the lack of an adequate water supply. The output implies that the orange trees in Latakia need to eat 15,000-18,000 m3/yr of water during the growing season. Compared to surface irrigation with 60% and drip irrigation which runs between 70–85% efficiency if the energy is reliable, solar irrigation systems can use as much as 90% of the water input. The annual water consumption rates are minimized to 12,000 m3/acre and equivalent surface irrigation cut back of solar irrigation systems because the common floor area in western Iran is said to be about30–40% of the hour riverine groundwater extraction sectors [4]. As there is no fuel or power drawn to the electronic grid, solar systems require low maintenance and operation costs making them an affordable solution providing a payback period of three to five years. The results of the research leads to an understanding of the citrus water requirements in Latakia, and show that solar irrigation represents an appropriate sustainable method for using these available water resources with low cost saving non-renewal sources and providing a non-dependent cultivation.
