NESTING BEHAVIORAL ADAPTATIONS OF ORANGUTAN (PONGO PYGMAEUS MORIO) IN COAL MINING AREA IN EAST KALIMANTAN

Coal mining changed forest structure and composition, it caused large negative impacts on the orangutan. In order to mitigate those negative effects, it is crucial to understand their nesting behavior adaptation in mining area. We investigated 74 times nested event in coal mining rehabilition area (CMRA) in East Kutai and 123 times in the Kutai National Park (Prevab) from October 2013 to September 2014 and include only night nests. We compared both habitats. Orangutans in CMRA built the nest later than in Prevab and used 15 species of trees as nests sites intensively on Senna siamea and Gmelina arborea. In Prevab, 35 species with the higher frequencies on Eusideroxylon zwageri and Dracontomelon dao. The average diameter of nest trees in CMRA smaller than Prevab. The height of nest trees in CMRA with the highest frequency was in 10.1-15 m, while in Prevab was as in 20.1-25 m. Orangutans in CMRA nested at the height of <15 m, lower than in Prevab was >20 m. Reused nest in CMRA was higher than in Prevab. Orangutans in CMRA more often built nests at the peak and limb, while in Prevab at the limb and peak. Orangutans in CMRA had learned to utilize various species and dimensions of trees as the place to build nests.

ANALISIS SPASIAL SEBARAN LAHAN KRITIS DI KPHP UNIT XII BATANGHARI PROVINSI JAMBI

Critical land occured as a result of land cover changes from vegetated into non vegetated land or the composition of the vegetation has changed. This study aimed to analyze the distribution of land critical at KPHP Unit XII Batanghari. Critical land analysis was based on the Perdirjen PDASHL Number P.3/PDASHL/SET/KUM.1/7/2018. Land is classified into 5 levels of criticality, namely: non-critical, critical potential, somewhat critical, critical and very critical. The parameters used in determining the level of criticality of the land are: land cover, erosion-prone class, slope class and the presence of land inside or outside the forest function. Spatial analysis used by Geographic Information System (GIS) and remote sensing technology. GIS is able to analyze and represent geographic phenomenon. Landsat 8 imagery was analyzed to obtain land cover clasification. The results of the analysis showed that critical land level of KPHP Unit XI Batanghari consisted of 3,609 ha (4.45%) that classified as very critical and 3,599 ha (4,43%) as critical land. Then, land with a somewhat critical level had the largest area, namely 26,024 ha or 32.07% of the total area of KPHP Unit XII Batanghari. The landcover was the main parameter to determine the level of criticality of the land. The openland cover type had the maximum score 60.

ANALISIS TEMUAN PATROLI POLISI HUTAN TERHADAP PERBURUAN SATWA LIAR DI RESORT WAY KANAN, TAMAN NASIONAL WAY KAMBAS

Hunting for wildlife in Way Kambas National Park (WKNP) is one of the leading causes of humans and animal conflict. So far, patrol activities are still considered less than optimal because of the decline in animal populations due to frequent hunting. This study aimed to analyze the findings of forest ranger patrols in protecting wild animals from hunting in WKNP. Data collection was carried out by observation, interviews and literature study. The data collected from the literature were then analyzed descriptively qualitatively. The results showed that during patrol activities, the finding of snares was still very much used by hunters and also found elephants that died due to hunting, although the range of forest rangers every year had increased but the number of personnel who did not match the size of the forest area made some areas not can be protected.

PENDUGAAN STOK KARBON PADA POLA TANAM AGROFORESTRI SEDERHANA DAN AGROFORESTRI KOMPLEKS DI KPH BATUTEGI, KABUPATEN TANGGAMUS

Global warming is a natural phenomenon that is currently taking place. Natural phenomena occur as a result of changing ecosystem balance. This can be minimized by adding vegetation which acts as an absorber of CO2 to convert CO2 into glucose and oxygen through the process of photosynthesis. Each type of vegetation has the potential to absorb different carbon, so this can be circumvented by using the right cropping pattern. Therefore, information about the potential for carbon stored in complex and simple agroforestry cropping patterns in KPH Batutegi is important. The purpose of this study was to analyze carbon stocks in agroforestry cropping patterns and to compare carbon stocks in simple and complex agroforestry cropping patterns in KPH Batutegi. Source of living tree biomass, dead tree biomass, understorey biomass, and litter biomass. The results showed that the carbon stored in complex agroforestry cropping patterns fell into the good category according to the Intergovermental Panel on Climate Change (IPCC). However, the stored carbon in complex agroforestry cropping patterns is greater than the stored carbon in simple agroforestry cropping patterns, namely 765.61 tonC/ha and 356.21 tonC/ha.
