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%.

Abstract

Field trial was conducted in the farming area in Parigi Moutong regency. Vigor test was performed in the SeedTechnology Laboratory, Agronomy Department Faculty of Agriculture Tadulako University. This trial lasted from 5 Februaryto 16 July 2006. The aim of this trial was to evaluate the effect of non-tillage and the application of low dosage Phosphorusfertilizer in the rice-field following rice sowing on the initial vigor of mung bean seeds produced. This trial used BlockRandomized Design in factorial pattern with three replications. Two factors tested, namely non-tillage practices with fourlevels, namely non-tillage, non-tillage + mulching, non-tillage + glyphosate, and non-tillage + mulching + glyphosate. Thesecond factor was Phosphorus fertilizer with four levels, namely without Phosphorus fertilizer, 1/3 of recommendedPhosporous fertilizer dosage (30 kg P2O5/ha); 2/3 of recommended Phosphorus fertilizer dosage (60 kg P2O5/ha); and as ofrecommended Phosphorus fertilizer dosage (90 kg P2O5/ha). Differences between treatment were determined by using LeastSignificant Difference test at 5% and 1%. Results of this tial showed that Phosporous fertilizer and non-tillage system did nothave interaction. Application of Phosphorus ar recommended dosage had the highest dried-seed yield per hectare, germination(97,50 %) and germination rate (29,457 %)Keywords : Seed vigor, non-tillage, and Phosphorus

Abstract

Respondent samples of 20 people were determined through a census technique.  Data was analyzed using a multi linier regression of Cobb –Douglas and income analysis.  The results showed that the independent variables (Xi) simultaneously affect the dependent variable of taro production (Y) significantly.  The value of Fcounted was 234.743>Ftable (8.66) with coefficient of determination (R2) was 0.988 indicating that 98.8% of the fluctuation of taro production can be explained by such variables as land area (X1), seed number (X2), labor (X3), education level (X4) and farming experience (X5) while the remaining 1.2% can be explained by other variable not included in the model.  Those variables mentioned above are simultaneously affecting the taro production significantly.  The regression coefficients at the 5% α level of those variables are 0.360, 0.240, 0.248, 0.136, and 0.064, respectively.  The average production of the taro farming system was 4.370 kg/0.43 ha of wet taro equal to 10,162.79 kg/2.35 ha.  The average income of the farming system was IDR 13,124,575/0.43 ha equal to IDR 30,558,290.79/2.35 ha per growing season.  The R/C value was >1 suggesting that the taro farming system is feasible to be developed. Keywords: Japanese taro, Income, and Production Factor

Abstract

The objective of this research were to identify the groups of secondary metabolites which act as bioactive in E. tirucalli plants, to isolate and determine those compounds, and to determine the bioactivity and toxicity of each purified compound. The research results showed that the extraction using ethanol solvent produced more extract yield of 6.6% (23.11 g)  compared  with acetone solvent (1.74% or equal to 6.08 g), while hexane solvent resulted in extract yield of 0.05% (1.74 g).  Isolation and purification of E. tirucalli leaf extract by ethanol solvent produced 5 metabolites compounds including alkaloid, flavonoid, triterpenoid, and hydroquinone.  While the acetone solvent produced 6 metabolites compounds including alkaloid, flavonoid, steroid, triterpenoid and hydroquinone. E. tirucalli leaf extracted by acetone solvent has highest toxicity, in which concentration of 2% was able to cause 50% mortality of P xylostella insects tested, compared with the ethanol solvent at a concentration of 3%.

Abstract

This research was conducted at Dungingis and Kapas Villages, Dako Pemean Sub District, Tolitoli Regency. The objective of the research is to determine the influence of production input uses and their efficiency in clove farming.  The inputs included number of productive trees, urea fertilizer, ZA fertilizer, phonska fertilizer, and labor. This research use Slovin equation in determining the number of respondents. The number of respondents was 75 clove farmers. Data was analyzed using multi linier function analysis of Cobb Douglas. The results of the research showed that the independent variables (Xi) such as the number of productive trees (X1), urea fertilizer (X2), ZA fertilizer (X3), phonska fertilizer (X4), and labour (X5) simultaneously had significant effect on the production as the dependent variable (Y). The coefficient of determination was 0.975 indicating that the fluctuation in the clove production can be explained by its independent variables by 97.5% while the other variables not including in the model was by 2.5%.  The efficiency analysis showed that the k value of the variable of the productive tree number (X1)was < 1 suggesting that this variable is not efficient from the point of price view. By contrast the other variable such as urea fertilizer (X2), ZA fertilizer (X3), phonska fertilizer (X4) and labor (X5) had k values> 1 indicating that the use of these inputs is not efficient yet from the point of price view, as well. Keywords :Clove production, efficiency, and production input.

Abstract

The research aim was to develop a mass rearing technique of D. thoracicus by means of creating an artificial nest and to apply such technique as means to control cocoa pod borer (CPB) in small holder plantations. The research was carried out using experimental design and survey methods. The research consisted of different stages of experiments: (i) application of the artificial nest in the cocoa plantation, (ii) data record of cocoa pod borer attack level, (iii) analysis of dispersal pattern, and (iv) analysis of the cocoa production. Results of the research showed that the population density of D. thoracicus in the artificial nest sited on the primary branch was 8-9 times (12 % - 15%) higher than that on the jetty stem and main stem. The application of D. thoracicus by the artificial nest for controlling CPB could suppress the percentage of pod borer attack by 5%, bean damage by 42.95% and bean weight reduction by 21.03%. The analysis of dispersal pattern, based on the distribution pattern by Southwood (1997) in which Z<-1.96 or x mean < S2, showed that during three periods of observations, D. thoracicus tended to cluster.
