Background: Centella asiatica (CA) or pegagan or horse foot leaves is one of the traditional plants widely used to treat various diseases. This study aims to evaluated the content of total phenolics and total flavonoids, as well as the antioxidant activity of Centella asiatica extracts from different methods and solvents. Methods: The sample was divided into three groups, (70% ethanol maceration, methanol maceration and water infundation). Total phenolic compounds in the extract were determined by the Follin-Ciocalteu method, total flavonoid content was determined by the aluminum chloride colorimetric assay method, and antioxidant activity was assessed by the immersion DPPH free radicals method. Determination data of IC50 was assessed by regression test and differences between the three extract groups were tested by ANOVA or Kruskal Wallis test. Results: The highest total phenolics and total flavonoid were obtained in Centella asiatica extract with water solvent, 251.88 ± 0.96 mg/g GAE and 7.26 ± 0.03 mg/g QE, followed by 70% ethanol and methanol. In addition, the best antioxidant activity was also shown in the extract with water, namely 24.09 ± 0.01. The difference test results between all groups showed significant results (p<0.05) in all parameters. Conclusion: The best content of total phenolic, total flavonoid, and antioxidant activity was obtained by infundation with water solvent. In the maceration method, the best content of the three parameters measured was obtained in the group with ethanol solvent.

Arable land-use conversion into activities of non-agricultural production may encourage the use of wet region for soybean production. In this respect, a research on the adaptability of 25 soybean varieties to saturated soil has been conducted in the field. A randomized complete block design with 3 replicates was used in this experiment. Results of the experiment showed the adaptability differences among the 25 soybean varieties tested. Based on their yield, soybean adaptability to saturated soil condition was not related to plant growth type, but could be influenced by plant age. With an exception for Tidar (a high yielding variety belonging to the intermediate age), the late varieties produced highe yield than that of the intermediate ones. It was concluded that the varieties belonging to high yielding ones were characterized by the existence of positive correlation of pod number with nodule number and relative growth rate and of nodule number with relative growth rate and leaves area index. Key words: Soybean, Adaptation, Saturated soil, Agronomic traits

Intercropping of maize, rice and cassava is commonly practiced by subsistent farmers on rainfed agriculture in Indonesia. In general, grain yield (if maize in intercropping is lower than in monoculture sole crop. This due to the fact that maize varieties planted in intercropping was bred and selected under elite, monoculture crop environment. Field experiments to evaluate grain yield relative stability (if the three selected maize breeding materials planted in association with rice and cassava were carried out In Pekalongan (Lampung), December 1994 - September 1995. All three breeding materials are relatively stable in respect to grain yield. Individual selection in MC-1 population will be practiced in association with rice and cassava.

Intercropping of Maize, Rice and Cassava is commonly practiced by subsistent farmers on upland agriculture in Indonesia. In general, grain yield of maize under intercropping is very much lower than under monoculture crop. This due to the fact that the variety of maize planted under intercrop was bred and selected under elite, monoculture crop condition. Three field experiments to screen maize breeding materials planted in association with rice and cassava were carried out in Pekalongan (Lampung), October 1993 - November 1994. Three out of 29 entry of maize were selected, MC-1 (optimistic), Wiyasa (neutral) and ICS1 Arj15F (pessimistic). Performance test on grain yield relative stability for three selected materials have to be done before practicing any form of improvement by means of selection.
