EFFECTIVENESS OF BOTANICAL BIOPESTICIDES WITH DIFFERENT CONCENTRATIONS OF TERMITE MORTALITY
Full text linkThe aim of this study was to determine the effect of botanical biopesticide extracts and concentrations on soil termite mortality of Coptotermes curvignathus, Holmgren. This research was an experimental study using a fully randomized design (CRD) consisting of 2 3-level treatments that were repeated three times. Treatment was a type of botanical biopesticide consisting of three levels, namely are A1 (papaya leaf), A2 (soursop leaf), A3 (lemongrass leaf). In comparison, the concentration of botanical biopesticide consists of three levels: B0 (without or as a control biopesticide), B1 (500 grams), B2 (1,000 grams) and B3 (1,500 grams) which have been repeated three times. The data that had been tabulated was then analyzed using Variant Analysis, and if there was any influence, the difference test was continued at 5 % and %. The results showed that the treatment of papaya leaf biopesticides (A1) had a faster reaction to the death rate of termite (95.6 % ) and the lowest was the death rate of soursop leaf (A2) termite (90.7 % ). In comparison, lemongrass (A3) caused soil termite mortality (94.1 %). In addition , treatment of biopesticide concentrations of B3 (1,500 grams) resulted in higher termite mortality of 96.67 %. compared to B2 (1,000 grams) with mortality of 94.07 % and B1 (500 grams) with mortality of 89.62 %.Whereas, for the interaction between the two treatments, the highest level of termite mortality was papaya leaf biopesticide with a concentration of 1,500 grams (A1B3) and termite mortality was 100 %
SIMPANAN KARBON SEBAGAI SALAH SATU INDIKATOR KESEHATAN HUTAN PADA HUTAN RAKYAT (Studi Kasus di Hutan Rakyat Kelurahan Pinang Jaya, Kecamatan Kemiling, Kota Bandar Lampung, Provinsi Lampung)
Full text linkGlobal climate change and forest health are currently two things that need to be studied more deeply. Forests store carbon, including in the community forests. A healthy forest can perform its function properly including as a carbon sinker as well as a carbon repository. This study aims to analyze carbon storage as an indicator of forest health in community forests in Pinang Jaya Village. The data were collected by using cluster plots based on the method of Forest Health Monitoring (FHM), totaling 15 units. The measurement method used is destructive and non-destructive. The result showed that the average carbon storage in community forests in Pinang Jaya Village is 54.59 tC/ha. The largest contribution to carbon storage was AGB with a percentage of 95.71%, followed by necromass at 4.23%, and 0.05% litter and understorey. Based on the results of the analysis, carbon storage can perform as an indicator of forest health in the community forests of Pinang Jaya Village with the bad, medium, and good categories. The plot clusters are in the Good category (70.61 tC/ha - 83.66 tC/ha), namely cluster plots 13, Moderate categories (57.55 tC/ha - 70.60 tC/ha), namely cluster plots 4 and 14, and the Bad category (44.49 tC/ha - 57.54 tC/ha), namely cluster plots 1-3, 5-12.15, with the percentage of each category of 7%, 13%, and 80%
PARTISIPASI PEMUDA DALAM PENGELOLAAN HUTAN KEMASYARAKATAN DI DESA KAHAYYA KABUPATEN BULUKUMBA
Full text linkThis study aims to analyze the level of youth participation in community forest (HKm) management, analyze the driving forces and restraining forces of youth participation in community forest management and formulate strategies for increasing youth participation in community forest management. The data obtained were identified and reviewed in the form of a frequency table of Arnstein's degree of involvement, then analyzed descriptively by the Forces Field Analysis and Focus Group Discussion methods. The results showed the level of youth participation was at the degree of non-participation, with a percentage of 71.43%. The factors that encourage youth participation consist of the group facilitator, group meetings, work plan documents, assistance from various parties, the formation of the Social Forestry Business Group (KUPS), and the desire of youth to participate. The factors that inhibit youth participation consist of: lack of youth knowledge in managing community forest, not yet implementing work boundary arrangement activities, youth are not involved in the process of making work plans, and community forest implementation is still carried out individually, the farming experience is still lacking, lack of group capital makes the price of raw materials unstable. An appropriate strategy for increasing youth participation in the management of community forest consists of Conducting meetings involving facilitator, farmer groups and youth to discuss the implementation of management activities (planning, implementation & evaluation) of the community forest-conduct socialization and meetings regarding the contents of the community forest documents that have been made. Make internal group rules regarding product sales prices. Enhance the role of KUPS and conduct training for KUPS administrators to increase their capacity. Youth participate in various types of training conducted by government and non-government organizations (NGOs)
PROBLEMATIKA HUKUM KESATUAN PENGELOLAAN HUTAN DI INDONESIA
Full text linkThe purpose of this research is to analyze the legal issues that cause FMUs to not work optimally in managing forests sustainably. Some of the legal issues analyzed are related to the institution, permit authority, funding, and RPHJP development. This research uses a statute approach and retrospective (ex-post) analysis by examining various laws and regulations in the forestry sector related to FMUs and its implementation. The results of this study indicate that the FMU has serious legal issues in terms of institution, permit authority, funding, and Long-Term Forest Management Plan/RPHJP development. From an institutional perspective, FMUs are at the crossroads of the authorities of the four directorates generals in the Ministry of Environment and Forestry. In terms of authority, FMUs are the spearhead of forest management at the site level, but FMUs do not have adequate authority in managing forests in their areas. Then from the funding side, FMUs are faced with a minimum budget as well as no guarantee of funding for their RPHJP. And finally, in terms of the RPHJP development, FMU faces serious challenges after the enactment of Law No. 23/2014, and laws and regulations overlapping, particularly those related to the implementation of DG Forest Planology Regulation No. P.5/2012.
ANALISIS SPASIAL SEBARAN LAHAN KRITIS DI KPHP UNIT XII BATANGHARI PROVINSI JAMBI
Full text linkCritical 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

STRUKTUR POPULASI BEKANTAN (NASALIS LARVATUS) DI RAWA GELAM
Full text linkNumber of proboscis monkey population in Cajuputi Swamp Forest is 258 individual. This population is strongly influenced by condition of its habitat which is to degradation to 3.417 hektar. The object of research is to analyzed structure of proboscis monkey population. Method of research are river survey (Sha et al, 2008) and concentration count (Anonymous, 1981; Alikodra, 2002). The avarage density of proboscis monkey in their homerange is 3 individuals/hectares, with 30,2% males and 48,5 % females. This population is slow growth because there is only one baby/year, this is also indicated by number of 14 individuals babies (5,4%) and 41 infant (15,9%) lower when compared to number of adult indiviuals, so it is very worryng for continued growth of the population
NESTING BEHAVIORAL ADAPTATIONS OF ORANGUTAN (PONGO PYGMAEUS MORIO) IN COAL MINING AREA IN EAST KALIMANTAN
Full text linkCoal 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
