Fusarium wilt in bananas is caused by Fusarium oxysporum f.sp. cubense (Foc). Foc is one of the soil-borne pathogens. The intensity of disease attacks in different conditions with very severe is conducive soil. Suppressive soil can suppress and control the rate of development of soil-borne pathogens. The aims of this study are to determine the physical and chemical properties of soil and environment against fusarium wilt and find out the effects and levels of nutrients from the addition of manure and silica to fusarium banana wilt. Supressive soil samples from Sarampad, Cianjur and conducive soil from Salaman, Magelang. Ambon Kuning banana cultivar derived from tissue culture were planted to find out effects of manure and silica against fusarium wilt. Suppressive soil has higher soil chemist including neutral pH, sandy loam of texture class, total N, total P, organic C, organic matter, available Si than conducive soil. Manure and silica addition have significantly suppressed fusarium wilt on suppressive soil. The final experiment suppressive soil has higher total N, total K, organic C and organic matter than conducive soil.

The purpose of the study to know characterization of humic and fulvic acids after three months decomposition by fresh organic waste and canning pineapples treatment at Ultisol Lampung. The research was designed with a completely randomized factorial design with three factors in the plot pots 165 cm x 165 cm x 55 cm. The first is fresh organic waste (200 ton.ha-1 chopper pineapple crops, 40 ton.ha-1 cattle manure, 40 ton.ha-1 cassava waste, 40 ton.ha-1 waste pump pineapple, 2 ton.ha-1 mill juice pineapple), and the second is depth on the soil (i.e. 0 - 15 cm, 0 - 30 cm and 0 - 45 cm), the each repeated three replication so total treatments are 24 plot pots. The results showed ameliorant treatment fresh organic waste and canning pineapples can increase the levels of C-organic from <1% to >1.5%. On the control (K0) in two months decomposition did not significantly different at 5%, but the decomposition of humic acid for three months showed significant differences in the treatment of K0, K1 and K2. Utilization of combinations of fresh organic waste and canning pineapples treatment at the depths (0 - 15, 0 - 30 and 0 – 45 cm) can increase the humic acid content about >1.5% in three months decomposition waste. The combination treatment of fresh organic waste and canning pineapples on Ultisol for three months decomposition, able to provide sufficient nutrients especially the availability of C-organic, humic acid and fulvic acid for growth pineapples.

Aren plant (Arenga pinnata) can produce industrial raw materials. Almost all parts of palm trees can be utilized, namely young and old leaves, young endosperms, stems, stem bunches of flowers, roots, and fibers. Sugar leaves used for the roof of the house or hut. Young endosperms are used for fleas as a mixture of food or drink. Stem aren tree can be taken flour for the manufacture of palm flour. The main problem is the unclear growth of aren trees caused by soil characteristics in various places. The objectives of the study were to: 1) understanding the effect of land characteristic on the growth of aren trees; 2) look for various growth characters of aren plants at different altitudes. The study was conducted by survey and observation. Location was selected by purposive sampling, i.e. areas with altitude (<600 m ASL, 600 to 700 m ASL, and> 700 m ASL). The results showed differences results. Aren plant cultivation techniques that include the way of nursery, maintenance and post harvest management not implemented in Kulonprogo region, especially Ngargosari village, Pagerharjo, and Nglinggo. There is influence of altitude factors of place, soil type, morphology, physiology, and biochemistry to growth and aren products.
