The study about “Evaluation of semi organic system on rice production at fifth plant season” whose purpose to evaluate the quality and rice yield at semi organic system at fifth plant season, its impact on soil chemistry properties and its properness to farmers. This field experiment has been conducted from May to September 2008 at Palur, Sukoharjo, with two factors. The first factor is anorganic fertilizer at recommendation dose (Urea 300 kg ha-1, ZA 100 kg ha-1, SP-36 150 kg ha-1, KCl 100 kg ha-1). The second factor is 30% of dose recommendation anorganic fertilizer (Urea 100 kg ha-1, ZA 30 kg ha-1, SP-36 50 kg ha-1, KCl 30 kg ha-1) and five tons organic fertilizer. The data was analyzed with T test to evaluate the differences of semi organic system and anorganic system. The experiment’s result shows that the semi organik system gives weight of dry straw which is higher than anorganic system. The yield of dry unhulled rice in semi organic system(9,2 ton/ha) isn’t significantly different from the weight which is compared with anorganic system (8,576 ton/ha). From the economic analysis, semi organic system gives higher profit than anorganic system. The rice quality (dust and fiber contain) in semi organic system is higher but protein contain isn’t different. Semi organik system gives organik matter contain (1,618%), KPK (14,454 cmol/kg), N total (0,368%), available P (0,368 ppm) and available K (164,96 me%) which is signiificantly higher but givew lower pH (5,5) than anorganic system.

The study site is administratively located at Ngadipiro village, Nguntoronadi subdistrict, Wonogiri regency with the total area of 663.61 ha. The coordinate of the study site lies at latitude of 7o52â€™00â€ â€“ 7o54â€™15â€ S and longtude of 110o57â€™45â€ â€“ 111o60â€™45â€ E and altitude of 196-427 m a.s.l. According to geomorphologic, the study site is a denudation hilly area, which severely scraped, with the type of primary land use is rainfed, which occupied by annual crops and seasonal crops. This reaserch were aimed at: 1) identify the physical problems and soil cultivation that have caused the land degradation; 2) obtain the alternative solutions for land degradation, which is suitable with the land physical condition. The type of this research is phenomenology description, with the method of surveying. Land mapping technique used the overlay of three maps, i.e: slope map, soil depth map and land use map, which is obtained from the interpretation of topographic map with the scale of 1:25.000. The obtained land unit was used for analysis unit. The land evaluation was carried out based on: 1) observations of land degradation indicators (land cover, outcrop, soil erosion, soil slide, bench erosion and soil depth); 2) soil erosion analysis with USLE formula, which described by soil hazard class. The alternative solution were based on the land degradation types, the threat levels of land degradation and the land management by farmers. Conclusions: physical problems found are: 1) the climate conditions promoted physical and chemical rocks weathering; 2) the volume of eroded soil corresponded to slope, which shaped â€œSâ€; soil management problem found are: 1) land management by farmers also could drive the land degradation, 2) the low level of farmers economical condition resisted the adoption of technology innovation by farmers. The alternative solution offered are minimum soil tillage (TOT) at 9, 10, 11 and 12 land units. On the other hand, the land units of 2, 3, 6, 7, 9, 10 and 12 required the roraks construction and the planting of cover crops and annual crops periodically.

Ginger (Zingiber officinale rosc.) is one of high-production commodities in Indonesia, particulary in Central Java Province. Nevertheless, in general ginger is usually traded in fresh ginger form or simple processing result, such as dry ginger or ginger powder. Ginger oleoresin is combination of resin and atsiri (volatile) oil derives from ginger powder extraction by using organic solvent. Oleoresin is used as food and beverage flavouring substance having taste and aroma characteristic similar to the original spices. In addition to give ginger hot taste, oleoresin is also hygienic as well as contains natural antioxidant. The research aims to find out whether or not the ginger powder size and submerging duration in ethanol as well as the interaction of them affect the oleoresin characterization produced. The experimental design employed was factorial design with two factors: ginger powder size variations (20 mesh, 30 mesh, 50 mesh) and ginger powder submerging duration variations in ethanol (extraction) (24 hours, 48 hours, 72 hours). The data was obtained from the submerging analysis, density, and solvalibility in alcohol, acid and ester values, as well as phenol content affects the oleoresin characterization produced; the smaller the ginger powder size and the longer the submerging duration of ginger powder in ethanol, the higher are the values of submerging, density, acid value, ester as well as phenol content. The interaction of them only affects the oleoresin density. The range of submerging value obtained is 8-14.5%; density 1.2252-1.2809; solvability in alcohol 1:6-1:10; acid value 0.560-2.248; ester value 5.416-14. 978 as well as phenol content 3-7%.

Club root caused by P. brassicae is the most important disease of Brassicaceae. In the fields, the pathogen can totally fail to harvest. The disease is difficult to control, because the pathogen can persist in soil far years although there is no host. Elimination of the pathogen in the infested soil is become an important tactic in control of soil born disease such the disease. The use of natural agents which save on environment is one of the interesting methods to develop. One of them is rock salt (NaCl). An evaluation of the effectiveness of NaCl for elimination of club root pathogen and its impact on growth of Chinese cabbage as indicator plant has been conducted. A mount of 13 factorial treatments consisted of 5 levels of concentration and 5 levels of frequency of dreanching application have been evaluated. The result showed that the soil drenching of NaCl dilution with some concentration and time application were effective to control club root on Chinese cabbage. A concentration of 0,5-1% NaCl could be considerable for control of club root on Chinese cabbage. Soil drenching of NaCl solution on two or one weeks before planting could be considerable in control of club root.
