Abstract

Rambutan is a tropical fruit that grow well in Indonesia and the peel is considered as waste. Many researchers’ showed that rambutan peel contains polyphenol that could be expected to avoid obesity.  The objective of this study was to explore the increasing production of local rambutan and to identify the promising phytochemical compounds on its peel as phytopharmaca candidate against obesity. Survey was conducted on the production of rambutan, potential plantation area, and marketing. Sample of rambutan peel collected from the sub-district Kanigoro, Blitar. Phytochemical compounds were analyzed using TLC, HPLC and FT-IR. Bioassay analysis used obesity rat models. The survey result showed a mean of rambutan production increased 2,6% in 2007-2012. Average production of rambutan 70-120 kg/tree. Vegetative multiplication usually done to maintenance of rambutan quality. The main compound of  Rambutan peel  extract (RPE) is flavonoids, tannins, ellagic acid and the major functional group of CH3, aliphatic CH3, and C=O. These compounds have a potential activity against obesity.  RPE 30 mg/kgBW dose was significantly inhibit the weight gain of obese rats and reducing the adipocyte size (p<0.05).Key words: potency, production, local rambutan, blitar, obesity

Abstract

The use of combination of specific endophytic in tidal swamps to control stem root disease as biological control agents has not been done. It is expected that this combination is able to continuously protect plants from pathogen interference. The research was carried out in type C tidal swamp in Banjar regency of South Kalimantan, from March to November 2011, temperature 29-32oC, and pH 4.0-5.5.  The method used was Split Plot design. Biocontrol preparation for both types of endophytic was applied in seeds in 7 days after planting (DAP). Observation on high intensity and plant diseases of planting stage on tidal swamps (taradak, ampak and lacak) was conducted. The results showed that there was a reduction of disease ranging from 58.70 to 87.29%. The application of combination of two biocontrol agents (T. viride PS-2.1 + P. fluorescent PS-4.8), (Fusarium non-pathogenic PS-1.5 + P. fluorescent PS-4.8) and (T. viride PS-2.1+ FNP PS-1.5) isolate gave the best inhibition result, reduced disease intensity, and increased plant height. The result of soil analysis before and after application of endophytic showed that there was an increase in soil fertility with the element addition of N, P, K and pH. Keywords:  stem rot, endophytic combination, paddy, tidal swamp

Abstract

This paper is about a critical study on corn (Zea mays) plant with a non linear approach, as it is slowly growth rate at the initial stage of the cycle, followed by a rapid growth stage to a critical point then the height growth rate began to decline, reaching to a stability phase. The purpose of this research is to develope such a model to fit the height growth of corn (Zea mays) plant given microbe combination of Ochrobactrum sp.and Bacillus megatirium treatment; besides, to compare  the plant absolute growth rate  model between plant with microbe and non microbe treatment . A simple sigmoid model is preffered as it is easier to interpret the parameters biologically.  The  result shows that Logistic model is better fit in describing the height  growth compare to Gompertz model, as it yields coefficient of determination is more than 99%.  This  model shows that the maximum  height growth rate happens in about  40 day after planting.  Based on the model, it showed that the absolute growth rate tend to be bell-shaped and right-skewed for Logistic and Gompertz respectively.Keywords : corn, Gompertz, height, Logistic, microbe

Abstract

Two-spotted spider mite (TSM) Tetranychus sp. is one of prey mites for phyotoseiid mite mass rearing.  Based on previous research that TSM population developed well on Mung bean (Vigna radiata) and Adzuki bean (V. angularis) as host plants, confirmed growth and development of TSM on both beans. Research was aimed to observe biology of TSM on three phases of Mung bean and Adzuki bean leaf such as at primary leaf unrolled completely (V1), at the 1st trifoliate unrolled completely (V2), and at the 2nd trifoliate unrolled completely (V3). Pre adult stadia, life cycle, male and female longevity, female fecundity of TSM, and trichome density were observed on petri dishes contained each leaf phase of beans.  Result showed that three leaf phases of beans did not influence significantly in all biological variables, except fecundity. TSM fecundity was the highest on V3 phase of Mung bean (86.90). Trichome density on Mung bean leaf surface per mm² was lower than Adzuki bean. Trichome density of upper leaf surface of V3 phase of Mung bean (10.53) and Adzuki bean  (3.07) were lower than V1 (13.20; 12.40) and V2 phase (6.20; 5.27). V3 phase of Mung bean was most suitable for TSM mass rearing.Key words:  fecundity, leaf phase, mass rearing, trichome density, two-spotted spider mite

Abstract

This research aims to evaluate the diversity of climbing trees for rattan in agroforestry system. The result of this research is expected to be applied as the standard to improve the management in rattan agroforestry. The research was conducted from June to December 2011 in three different villages: Kalemei, Hiran and Liting in Katingan regency, Central Kalimantan. The data were collected via purposive sampling in two different types of land cover i.e rubber agroforestry (RA) and secondary forest (SF), each of system  had 6 plots and 18 sub-plots of experiment. The evaluation of species diversity was performed by measuring species richness, Importance Value Index, and Diversity Index. Statistic model was constructed by employing the approach in multivariate analysis and cluster analysis. The results indicated that SF had higher species diversity (3.02 – 3.45). The diversity level of RA was higher in Hiran village (3.96), than in the other two villages (<3.0).  Habitat similarity was characterised by the similar composition and structure of vegetation of both SF and RA in Hiran and Kalemei, but not in Liting. The potential of supporting trees for rattan in RA is rather high as shown by high species density and the presence of trees with high wood density (0.75-0.9g cm-3) to extremely high (>0.9g cm-3) as it found in SF.Keywords: Rattan, rubber agroforestry, climbing trees for rattan, secondary forest
