Abstract

Environmental Management effort in conservation will be required to diverse natural resources value, and as a form of favouring the sustainability of biological natural resources and its ecosystem utilization in City Forest of Telagasari (HKTs). HKTs have been designated as a green open space and it is developed as a protected area and education center of biodiversity in Balikpapan City. Data collection was done by direct observation method on terrestrial fauna and flora. There are 133 kind of flora in HKTs (11 flora are protected by IUCN and 14 flora are  protected by PP RI in SK/54/Pertanian/1972) with a Shannon-Wiener Index (H’) 3.04 for ‘semai’ category, 3.02 for ‘pancang’, 3.02 for ‘tiang’, and 1.86 for ‘pohon’ category. The numbers of avifauna that had been recorded in city forest of Telagasari are 35 species (7 has important protection status), with a Shannon-Wiener Index (H’) of 2.762. The numbers of mammals that had been recorded in city forest of Telagasari are 7 species and 21 individuals, with H’ mammals of 1.5. This inventory data and information can be used to support the conservation, as an environmental management effort. The baseline of biodiversity and conservation status in HKTs Balikpapan will be measured as a key parameter for the implementation of biodiversity protection program. The strategic planning and program that are proposed for next fifth year for HKTs may give a positif impact for biodiversity and conservation in HKTs.

Abstract

The aim of this research was to examine in vitro and in vivo anti fungal activity of citronella leaves extract against Colletotrichum sp caused antrachnose disease on chilli. The in vitro and in vivo research used randomized completely design (RCD) with one factor and five level. The factor was citronella leaves extract and the level were 0,1 % (v/v), 0,2 % (v/v), 0,3 % (v/v), 0,4 % (v/v), 0,5 % (v/v). Negative control treatment was conducted by growing Colletotrichum sp on PDA (in vitro) and chili (in vivo) without citronella leaves extract while positive control was conducted by growing Colletotrichum sp on PDA (in vitro) and chili (in vivo) containing synthetic fungicide. The in vitro study showed that the higher concentration of citronella leaves extract caused higher growth inhibition of Colletotrichum sp. Whereas the in vivo study resulted that higher concentration of citronella leaves extract caused lower incubation period of Colletotrichum sp, intensity of disease and weight loss of chillies. The highest concentration of citronella leaves extract (0,5%) has higher antifungal activity compared to other treatments and negative control while lower than positive control.
