The large amount of acid sulphate soil area may be potential for agricultural development. Low soil pH, low to very low P availability and high Fe concentration are the dominant characteristics of acid sulphate soils. Low availability of P in acid sulphate soil may due to fixation process by iron and aluminum. Low N, low available K, and potential toxicityof Fe and Al are other characteristics of acid sulphate soil. Optimum agricultural management practices are required to leach the excess of Fe2+ and to maximize the P availability in order to obtain favourable conditions for rice growth. Rice straw application is part of technology for acid sulphate soil productivity improvement, a simple tecnology that sustainable and environmental friendly. Organic matter being a source of nutrients has also an important role in relation to P sorption capacity of soils through Fe chelation processes.

TEKNOLOGI PENURUNAN KADAR Fe AIR SAWAH PASANG SURUT MELALUI PENGGUNAAN BIOFILTER PURUN TIKUS (Eleocharis dulcis) [Fe Levels Decline Technology of Water Tidal Rice Field by Using Purun Tikus (Eleocharis Dulcis) Biofilter ] Indrayati, Linda; Susilawati, Ani

Water management in acid sulfate soil can increase the productivity of land and crops, but the element of poison leaching into drainage channels gives negative impact on the environment. One approach to improve water quality is to filter or absorb the poison element. Purun tikus (Eleocharis dulcis) can act as a biofilter to improve water quality. The purpose of this study is to get biofilter technology (purun tikus) to reduce the levels of Fe, SO4 and increase the pH of the water. The experiment was conducted in greenhouse of Indonesian Swampland Agriculture Research Institute, Banjarbaru, South Kalimantan. Treatment was arranged in a factorial randomized block design with three replications.The first factor was the density of the biofilter ,consisted of: 1) 25%, 2) 50%, and 3) 100%, The second factor was the length of contact of water with biofilter that consisted of: 1). 12 hours, 2) 24 hours, and 3) 36 hours. The results showed that the density of purun tikus 50% in greenhouse experiments can decreased the concentration of Fe at 76.5%.

Tidal land large enough sour sulfate and the potential for agricultural expansion. Obstacles encountered primarily stress iron poisoning. It has the potential to cause a decline in rice yield research aims to study the effect of the influence of seed treatment and fertilizer P and K to control iron toxicity in acidic sulfate potential land. This research was carried out in KP Belandean on MK 2007. Randomized block design with 3 replications. Rice varieties used were Batanghari, planted on plot measuring 4 mx 9 m with a spacing of 20 cm x 20 cm. Package combined treatment of seeds and fertilizer P and K: 1. (25-90-75), 2. (50-90-75), 3. (75-90-75), 4. (100-90-75), 5. (125-90-75), 6. (75-30-75), 7. (75-60-75), 8. (75-120-75), 9. (75-150-75), 10. (75-90-25), 11. (75-90-50), 12. (75-90-100), 13. (75-90-125), 14. (0-90-75), 15. (0-0-0) kg / ha% CaO-kg / ha P2O5-K2O. The result showed that by giving a dose of phosphate fertilizer 90 kg/ha P2O5 and potassium at a dose of 100-125 kg/ha K2O CaO combined with the provision of 75 % of the weight of the seed, is the combination to control iron poisoning.

Technology of microbial utilization to accelerate the oxidation of pyrite followed by leaching (bioleaching) has the potential to resolve problems in land management of actual acid sulphate soil. The research aims to obtain a bioleaching technology package that can improve the productivity of the actual acid sulfate soil. The experiment was conducted on tidal swamp land that has soil type of actual acid sulfate at Wana Raya sub-district, district Batola, South Kalimantan, in July - November, 2014. The study was designed by using strip plot with three replications. The treatment consisted of two factors, namely application of an oxidizing microbial pyrite and leaching amount (intensity). The main plot consisted of (P0) without leacing (naturally), (P1) six times leaching , (P2) eight times leaching, and (P3) 12 times leaching. Subplot consisted of (M0) without oxidizing microbial pyrite, (M1) with oxidizing microbial plant used in this study is Inpara 3 of rice variety. Observations were made on soil pH, oxidizing bacteria pyrite, growth of rice plants (plant height and number of tillers) and rice yield. The results showed that the main problem of actual acid sulfate land studied is a high soil acidity (pH of 3.44). Influ-ence of leaching was greater than microbial application on crop yields. Application of the pyrite oxidizing bacterial and leaching eight times gave the best influence on the growth and yield of rice plants.

The أرني الله anthology is the work of Taufik El-Hakim with the theme of philosophy. In the short story anthology, there are three short stories had been researched, namely, الشهيد , وكانت الدنيا, and المرأة غلبت الشيطان. The three short stories have similarities, such as the emergence of personage devil with with different characters, and the use of words and sentences have the shape of signs. Based on the uniqueness and the problem, the researcher reveals that the three short stories using Charles Sanders Pierc's Semiotic analysis knife. The method is descriptive qualitative method, the primary data source is the anthology of the short stories أرني الله by Taufik El-Hakim, and secondary data comes from books and other supporting articles. The research results are icons, indexes, and symbols which is found in the three short stories, such as the word "in the Roma’s body" in the short story الشهيد which is an iconic sign from the word region or city. The sentence “They knelt except the devil. He looked at the miracle for a while, then turned his neck and shuddered and continued to heaven with a light walk" in the short story وكانت الدنيا which is an index sign of arrogance, and the word "Spring" in the short story المرأة غلبت الشيطان which is a symbol of prosperity. There are parallels The nature of the devil in the three short stories is the character of the protagonist and the character of the antagonist.
