Eucalyptus pellita F. Muell plantation in Riau Province applying the clear cutting silvicultural system on fast growing tree species allegedly have an impact on the changing of watershed hydrological functions. The aim of this study was to determine the changes in the chara cteristics of after logging stream flow hydrograph of E. pellita forest stand. The research was carried out in E. pellita plantations in Perawang, Riau Province using 4.62 ha of micro catchment as an observation unit. The method used is the analysis of hyd rograph units on chosen data of flood hydrograph. The research concludes that clear cutting system has led to increasing the peak flow discharge from an average of 0.226 m 3 .s 1 to be 0.322 m 3 .s 1 , shortening the time base of hydrograph from an average of 1 43 minutes to be 90 minutes, shortening the time to peak flow from an average of 80 minutes to be 40 minutes, as well as declining the base flow from an average of 0.0056 m 3 .s 1 to be 0.0032 m 3 .s 13.s-1to be 0.0032 m3.s-1.

Improper seed handling of Eucalyptus pellita will reduce seed quality, so as to improve the viability of the seed proper handling techniques are needed. To investigate the seed germination potency as a result of seed handling germination seed tests are needed. The purpose of this study was to examine the effect of germination method and paper substrate on the viability of E. pellita seeds. Seeds used in this study were from seedling seed orchard in South Sumatra, South Kalimantan, and Riau. Seed germination methods used in the laboratory tests were method of top paper and between paper tests, besides that, different papers were used such as: paper substrate namely straw paper, towel paper, filter paper, and newspaper. Factorial experimental design completely randomized was used. The results showed that: (1) the method of germination and paper substrate was significant (2) the best paper substrate and germination method was the method of top paper test with used media of newspaper (germination percentage 204 seedling /0.01 grams).

Shorea assamica Dyer is one of the forest trees with recalcitrant seed type, It can not be stored for long periods. Storage technique of planting material in the form of seedlings is one solution that can be done to overcome the problems of the seeds with a short shelf life. The aim of the research is to determine the growth response of S. assamica seedlings to shading andgrowth inhibitor treatments. Research design was approached by split plot design. The main plot was shade and sub plot was a growth inhibitor. The storage conditions consisted of (1) light (38,600 47,200 lux), (2) medium (19,342 35,300 lux) and (3) heavy shading (62 2,106 lux). The inhibitors used were (1) paclobutrazol 250 ppm , (2) NaCl 0.5% and (3) aquadest (as a control). The results showed that the combined treatment of paclubutrazol 250 ppm with heavy shade was able to suppress the growth of height, dry weight of root and seedling quality index of S. assamica at the age of 6 months optimally in nursery.

Collaborative management is the most appropriate strategy in an effort to accommodate the interests of local communities in the management of protected areas. Success of collaborative management is highly dependent on the extent of identification of key factors for strategy success to compile scenarios into operational recommendations. This study aimed to formulate a collaborative management strategy for Bantimurung Bulusaraung National Park (Babul NP) based on scenarios that may occur in the future. The study was conducted by observation, interviews and questionnaires to a number of expert informants and literature studies. Data was analyzed using a prospective analysis. The results showed that the development of collaboration in the future is an optimistic scenario with the increasing awareness of the interdependence of interests, improving human resource competencies, collaboration, the ability to build networks with other stakeholders, improving the ability to coordinate with relevant stakeholders and the ability to establish cooperation with them and the adequation of goverment policies to give a place to people in the utilization of the Babul NP. Application of collaborative development scenario is expected to improve Babul NP management.

There are two possibilities on open pollination: cross pollination and self pollination. This research was aimed to identify cross pollination potential within and among provenance, and to determine the flowering behavior of each provenance in seedling seed orchard of cajuputi at Paliyan, Gunungkidul. The research was conducted based on flowering phenology (start of flowering, end of flowering and duration of flowering in one period) for all flowering trees during two flowering periods. The result showed that there was high crossing potential in seedling seed orchard of cajuputi based on flowering synchrony. Land race of Gundih has highest crossing potential due to longevity and intensity of flowering, while the provenance from Northern Australia has the lowest crossing potential. Other provenances (Masarete, Rat Gelombeng, Waipirit, Pelita Jaya, Cotonea, Suli and Western Australia) also have high crossing potential at the time when the number of individual was greatest and flowering intensity highest. This research demonstrated that high crossing potential was found within provenance and among provenances except Northern Australia. The implication of this research deployment of improved seed produced from open pollination in seedling seed orchard was recommended for high crossing potential expressed from flowering synchrony.

Indonesia is one of the mega-biodiversity countries that have a great responsibility in maintaining the balance of the global climate and forest ecosystems. Drought causes shifting of ecosystems causing disturbances on animal life leading to death of species. Alongside fires in the savanna, drought is a recurrent problem in the park, which occurs every year. This study aims to detect the abundance of water by using satellite imagery in Baluran National Park (BNP). The research analyzed using Landsat satellite imagery ETM7 + in 1999 and 2010 and three (3) main factors that have great potential abundance of water, are: (1) plant density (GI = Greenness Index), (2) soil moisture (WI = Wetness Index), and (3) soil conditions (SBI = Soil Brightness Index). Three factors are summed and divided by three to get 5 levels of water abundance: 1) Very abundant, 2) Abundant, 3) Medium, 4) Few, and 5) Very little. The results showed that the abundance of water decreased between 1999 and 2010 for moderate conditions from 85% to 38%, if the abundance of low water (slightly) increased from 15% to 60%. The level of accuracy of the abundance of water in the field of more than 80% is exactly 91%. The extreme drought conditions will be very dangerous for the survival of flora and fauna in Baluran National Park that are in desperate need of water and potentially in danger of a fire. Construction of water reservoirs and water supply continuously using a water tank in the dry season is very necessary in the Baluran National Park.

Information on the relationship of rainfall with discharge and sediment are required in watershed management.This relationship is known to be highly nonlinear and complex. Although discharge and sediment has been monitored continuously, but sometimes the information is not or less complete. In this condition, modeling is indispensable. The research objective is to create a model to predict the monthly direct runoff and sediment using Artificial Neural Network (ANN).The model was tested using rainfall data at t-3 and t-4 as input, and discharge and sediment at t+3 and t+4 as output. The data used is the data from 2001 to 2014. The results showed that of some models tested there are two models for the prediction of discharge and two models for sediment.The model was chosen because it has the smallest MSE, the largest R2and satisfying K (0.5 to 0.65).Thus,these models can be used to predict discharge andsediment for a period of t+3 and t+4.Prediction of discharge of t+3 and t+4 may use Q t+3= 0,64 Q t-3+ 0,05 and Q t+4= 0,65 Q t-4+ 0,074 res pectively, while for predicting sediment of t+3 and t+4 may use equations QS t+3= 0,45 QS t-3+ 0,052 and QS t+4= 0,45 QS t-4+ 0,052. This ANN modeling can be applied to predict the flow and sediment in other locations with an architecture adapted to the conditions of available data.

The Red and blue lory is an endemic parrot species from Talaud Islands, North Sulawesi. The use of existing resources is suspected that occurs of selection including the roosting trees. The research aims to identifying the characteristics of Red and Blue Lory roost tree and determining variables in its selection. We measured 14 variables to identify the characteristics and selection of roost tree. Mann-Whitney test, T-test, Chi-sqare test and Binary Logistic Regression were employed to analyze data. We detected 11 roost trees in study field, there are Gehe (Pometia coriacea Radkl) nine individual, Binsar (Ficus variegata) and Lawean (Sterculia sp) one individual. The Chi-square test identified five variables which related to roost tree selection, i.e; branch-free bole length, canopy diameter, canopy density and the number of trees around the roost tree on diameter 20 - 40 cm and > 41 cm. The Logistic regression analysis detected three variables that gave the most influence on roost tree selection, but branch-free bole length gave the most influence on roost tree selection.
