An Analysis of Functional Groups and Potential Values of Herbaceous Species of Grasslands in West Timor, Indonesia

This study was to determine the composition of plant functional groups and the potential value of herbaceous species present in grassland communities of West Timor. Ten stations in grassland of Kupang West Timor (Penfui, Alak, Bakunase, Tode, Mulafa, Oesapa, Tanah Merah, Tilong, Bukit Cinta, and Naketuka) were selected and at each stations, 15 plots 1 m x 1 m (∑150) were randomly place. In each plot, all herbaceous presents were recorded. Each plant was further classified into four functional groups, whether grasses, sedges, legumes, or forbs. Plants were also grouped based on their potential whether they were food plants, medicinal plants, ornamental plants, forage plants, or poisonous plants. For each species present, the number of individuals, dominance, frequency, and Importance Value Index (IVI) were calculated. From 150 plots, there were 134 herb species from 32 families. Of these species, grass (Poaceae) was 26 (19.40%) species (IVI 25.24%) while non-grass was 108 (80.60%) species (IVI 74.76%). Grasslands were dominated by non-grass species. Based on the IVI, plants were dominated by Euphorbia hirta L. (IVI 13.93%), Eleusine indica (L.) Gaertn. (IVI 12.46&), Cyperus rotundus L. (IVI 11.72%), Digitaria ciliaris (Retz.) Koeler (IVI 11.12%), Senna tora (L.) Roxb. (IVI 9.54%), Stenotaphrum secundatum (Walt.) Kuntze (IVI 9.35%), and Tridax procumbens L. (IVI 9.17%). Of the 134 species, the forbs was 77 (57.46%) species (IVI 54.75%), grass 26 (19.40%) species (IVI 26.25%), legumes 20 (14.93%) species ( IVI 12.41%), and sedges 10 (7.461%) species (IVI 6.09%). Grasslands were dominated by forbs based on the number of species and IVI. Of the existing species, 43 (31.34%) were food plants (IVI 34.62%); 77 (67.46%) were medicinal plants (IVI 61.97%); 14 (10.45%) were ornamental plants (IVI 11.45%), 23 (17.16%) were forage plants (IVI 25.14%), and 5 (3.73%) were poisonous plants (IVI 2.31%). The grassland was dominated by food plants and medicinal plants. Although the herbaceous in the grasslands of West Timor were generally seen as weeds, the potential of grassland to provide medicinal, food, ornamental plants, and fodder was quite large. Nearly 70% of the species were potential for medicinal, almost 50% were potential for food, and more than 10% were potential for ornamental plants. It is necessary to further explore the economic potential of these grasslands. The high dominance of forbs compared to grasses and legumes may be an indication that this grassland has been severely invaded by weeds and has experienced disturbances. The composition of grassland vegetation, in general was less than ideal as a grazing area. Efforts were needed to improve the legume, suppressing weed invasion and poisonous plants, and human interference in the area must also be reduced.

The role of oral mifepristone in pre-induction cervical ripening at term

Background: Planned induction of labor is an established part of modern obstetrics and is used as a definite form of treatment where continuation of pregnancy would be detrimental to the health of mother or fetus. The objective of this study was to evaluate the effect of mifepristone in pre-induction cervical ripening and labor induction.Methods: A total of 200 pregnant women at term with Bishop Score 4 or less were selected for this prospective randomized placebo-controlled study. The sample was equally divided into study group to receive 200 mg of mifepristone and control group to receive placebo orally for 2 days. Bishop score was assessed at every 24 hours interval till patient entered in spontaneous labor or 72 hours after 1st dose. Women who did not enter labor spontaneously, labor induction was planned with per vaginal insertion of prostaglandin (PG) E2 analogue, Dinoprostone gel 2.5 mg or PGE1 analogue Tab. Misoprostol 25 µg.Results: Ninety-six subjects in the study group and eighty-one in the control achieved successful ripening of cervix and the difference was statistically significant. Sixty-eight of study group and thirty-nine of placebo group entered in spontaneous active labor within 72 hours. Requirement of oxytocin as adjuvant treatment was significantly lower in the study group. Nineteen women of study group and fifteen of control group delivered within 24 hours, and eighty-one of study group and sixty-two of placebo delivered in 48 hours. The mean induction delivery interval was 35.53±13.67 hours in the study group, whereas it was significantly prolonged in the placebo group 50.49±20.92 hours. Eighty-two subjects of study group and seventy-eight of the control group delivered vaginally, the differences were statistically not significant.Conclusions: Mifepristone was found to be an effective agent for cervical priming prior to labor induction in women at term and significantly reduces the induction delivery interval compared with placebo
