Abstract

The research aim was to find out the effect of seed scarification and germination substrate upon seed viability and seedling vigor of aren.  The research applied a randomized block design with factorial pattern consisting of two factors.  The first factor was scarification treatment: without scarification, scarification at 400C, scarification at 400C and soaked in 0.5% KNO3 solution for 36 hours.  The second factor was germination substrate:  sand, rice hull coal, cocopith, mixture of soil taken from natural palm growth area and organic material at a ratio 1:1, and mixture of 1 g NPK fertilizer with 1 kg soil taken from palm tree forest area and organic material media.  The greatest seed germination of 83.33–86.67% with germinating speed of 0.85-1.04 %etmal was found in the scarification at 400C soaking in 0.5% KNO3 solution for 36 hours and soil organic and matter treatment. This treatment also resulted in normal vigorous seed indicated by higher dry content weight and hypothetic vigor index than any other treatments.

Abstract

The objective of this research was to evaluate the potential ability of sonic bloom technology and organic fertilizer application on shallot production. The experiment was arranged in a split-plot design. The organic fertilizer application was the main plot while the sub-plot was the sonic bloom application. The shallot variety Kuning was used at this experiment. The experimental results indicated that the sonic bloom and organic fertilizer application increased the shallot yield.  The highest yield was found in the sonic bloom and organic fertilizer combination, followed by the sonic bloom, and the organic fertilizer treatments. The yield of shallot applied with sonic bloom and organic fertilizer was 26.43 t ha-1. The yield of shallot applied with sonic bloom, organic fertilizer, and the control were 23.39, 21.98, and 19.58 t ha-1, respectively. MBCR of sonic bloom and organic fertilizer combination, sonic bloom, and organic fertilizer applications were 8.05, 6.91, and 5.73, respectively.

Abstract

Soil microstructure as affected by organic matter and calcium was investigated by polarising microscope examination after three months incubation and by scanning electron microscopy (SEM) after one month incubation. Both polarising microscopy and SEM observations revealed an improvement of soil microstructure with the addition of cow dung and wheat straw.  Compared to the addition of dung, the straw amendment resulted in a greater microorganism diversity and lager porosity values.

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 identify the physico-chemical and sensory characteristics of aren instant starch noodle (ISN) substituted with 0, 5, 10, 15, 20, and 25% of tapioca starch.  The physicochemical and sensory characteristics observed were gelatinization level, water content, white degree, cooking rate, cooking loss, tensile strength, elongation, texture, performance, aroma, taste and viscosity.  Corn ISN was used as a comparison. The research results showed that the percentage of the tapioca starch that could substitute the aren starch was in the ranges of 5 – 20%.  Substituting with 20% tapioca starch could yield ISN most similar to the corn ISN in which physicochemical and sensory characteristics were acceptable to consumers.  However, the water content of the ISN resulted from the research still higher than that of standard category, therefore the time length for drying need to be prolonged.

Abstract

The aim of the research was to determine the physiological ripen time of mengkudu seed based on penology study. The study was conducted in the Green House and Experimental Farm of Jurusan Biologi FMIPA Universitas Negeri Makassar (UNM). Penological observation was done since the beginning of flowering until the fruit formation was completed and mature. The experiment conducted used three trees, in each tree three branches with all their blossoming flowers were labeled for observation.  Therefore, there were 3 x 3 = 9 branches including their flowers were observed for the flower transformations and development, fruit formation and fruit maturity stages. There were three stages found for the mengkudu fruit to reach maturity.  Such stages were stage M-1 (perfectly           fruit formation), stage M-2 (morphological mature), and stage M-3 (physiological mature). Based on visual observation, the exocarp changes were followed by mesocarp (fruit meat) and endocarp            (seed skin) transformations.

Abstract

The Objective of the study was to identify microhabitat characteristics in natural nesting ground as a basic form of egg hatching of maleo birds for ex-situ habitat in Lore Lindu National Park. Survey methods and experimental design were applied in this study using Saluki Nesting Ground as a habitat model. In a natural habitat, variables observed were microclimate condition (temperature and humidity, depth and diameter of holes) while in an artificial habitat where four different forms of eggs hatching (in-situ, ex-situ, incubator by means of media rack and sand) were applied temperature, humidity, hatching quality, incubation time, hatching weigh, and mortality were determined. Data analysis applied was descriptive analysis and multivariate test using SPSS computer program. Results of the study showed that in the natural nesting ground the temperature ranged from 30 to 35 oC with an average temperature of 33.03oC, and the humidity from 60.20 to 71.10% with an average humidity of 68.55%. The hole diameter ranged from 28-63 cm with an average hole diameter of 41.64 cm and the hole depth from 51-87cm with an average hole depth of 63.29 cm. The application of hatching method was resulted in the in-situ temperature and humidity of 32.90 oC and 68.41%, respectively, and the ex-situ of 31.68 oC and 67.52%, respectively, rack incubator of 33.99 oC and 70.06%, respectively, and sand incubator of 33.78 oC and 71.02%, respectively. The longest incubation time was found in the ex-situ semi natural hatchery which was 78.40 days, followed by the in-situ habitat 63.48 days, rack incubator 59.40 days, and sand incubator 59.33 days. The best hatching quality was found in the rack incubator, but the mortality rate was highest. The application of incubator for egg hatching of maleo birds could reduce the incubation time length and increase the hatching quality
