Abstract

The field observation of this research was conducted from June 2005 – May 2007 in tropical rainforest at Lore Lindu National Park Central Sulawesi. The main objectives of this research  were to study  (i) the relationships between interception loss and rainfall properties and vegetation characters and to determine the dominant factors affected (ii) the effect of  rainfall interception on energy flux and mass transfer and  (iii) the dynamics of vertical energy flux under the forest and grass land. Rainfall interception was  36.34 % of gross rainfall in 200 events, Depth rainfall and LAI factors had strong effects on rainfall interception. The relationships could be expressed  as  Ic = 0.980+0.239P+0.035LAI  (R2 = 0.78).  The output of this equation was compared with Gash model and the observation value showed that deviation of the equation was  1 % and less than Gash model, so that equation gave as good result as Gash model gave. By considering the data requirements and calculation procedures it was concluded that this equation is applicable for interception prediction. Land use type had effects on  radiative and energy balance. Net radiation (Rn) in the forest was 10.66 MJ/m2/day and higher than  in the  grass land where incident global radiation was similar. Vertical latent heat flux in the forest was 9.53 MJ/m2/day or 89.40% Rn in rainy day and  8.41 MJ/m2/day or 74.56 % Rn in   dry day, on the other hand,  in the grass land, sensible heat flux was higher  than latent heat flux of all weather condition.  Direct effect of rainfall interception on energy flux  and mass transfer might be described that is needed latent heat 9.0 MJ/m2/rainy day to evaporate the rain intercepted of 3.69 mm/rainy day. Effect of rainfall interception had positive correlation with  latent heat flux and the negative correlation  with sensible heat flux.

Abstract

The research aimed to formulate a custom forest management compliance with forest land functions in the Toro custom forest area according to forest land functions.  The analysis method implemented for formulating the custom forest management is a comparative analysis, with which the land categorization concept according to Toro custom norms was compared with the forest management concept according to the Government Regulation Number 6, 2007.  The research results showed that the Toro custom community has already got hold of the knowledge system about land use management based on land biophysical characteristics.  In terms of area management aspect, there was indistinct forest management yet in the field among various kinds of custom land categorization implemented.  Meanwhile in forest management aspect, particularly in custom forest area utilization, there was a difference in term of the interests between the custom land categorization and the government regulation number 6, 2007.

Abstract

In Indonesia, meat supply is much less than the demand.  The national meat production in 2006 was 2.070.234 t year-1 (DJP 2006) whereas the demand for meat was 2,957,477 t year -1.  In Central Sulawesi forest, anoa has been utilized by the people around the forest as an alternative animal meat to meet their demand for meat.  A mountainous anoa has an average body weight of 40 kg and fresh feed intake of 7-10 kg day-1 animal-1. The biological characteristics of anoa allow the anoa to be domesticated easily as a source of meat animal in the areas around the forest.  There is a lack of study in the aspect of anoa meat nutrition; as a consequence information on such aspect is limited.  Thus, information about anoas response on feed manipulation is necessary.  The present experiment was conducted to study the responses of anoas on feed manipulation.  The experiment was conducted in Palu, Province of Central Sulawesi.  Feeding trials were designed to study the effect of combination of pokae fruits and spinach levels in feed on feed intake, weight gain (WG) and feed efficiency. The treatments were allocated in a 6 x 6 Latin Square design. Analysis of variance and Duncan’s test were applied to analyze the data obtained. Feeding of 5 kg pokae and 1.5 kangkung (R4(5.0/1.5)) diet resulted in the highest intake dry matter, crude protein, Ca, P ,crude fiber, and weight gain of 1.29 kg, 0.60 kg TDN, 0.17 kg, 0.0124 kg and 0.0103 kg, 0.46 kg and 0.516 kg day-1 animal-1, and feed efficiency of 4.3%.
