Abstract

ABSTRACT The research aim was to identify the characteristics of cacao farmers and factors influencing cocoa production in Parigi Moutong Regency.The research location was determined based on a Purposive method. The method to select farmers as respondents was a Simple Random Sampling. The sample size for the research was 49 respondents of 493 cocoa farmer populations. Tool analysis used to investigate factors influencing cocoa production in the research was the Cobb-Douglas production function analysis. Based on the data analysis, it can be concluded that land area, use of side grafting seedlings, fertilization, sarungisasi technology, herbicide and the farmers’ experience significantly influenced the cocoa production, whereas extension intensity had no effect on the cacao production.

Abstract

ABSTRACT The experimental study was carried out in Kassi-Kassi Village, Tamalate District, Makassar to study the effect of dekaform fertilizer and defoliation on the growth and production of okra.  The method of the study employed a Randomized Block Design with six treatments :i) Without dekaform and without defoliation; ii) one dekaform tablet and without defoliation; iii) two dekaform tablets and without defoliation; iv) without dekaform and with defoliation; v) one dekaform tablet and defoliation; vi) two dekaform tablets and defoliation.  The results showed that the treatment of two tablets and defoliation produced the largest plant height, number of pods per plant and production of young pods per hectare.

Abstract

ABSTRACT The research aim was to study the growth of Dendrobium applied with various concentrations of super bionik fertilizer. The research conducted used a Randomized Block Design consisting of 6 treatments: without super bionik fertilizer, 1 ml super bionik fertilizer/l water, 2 ml super bionik fertilizer/l water, 3 ml super bionik fertilizer/l water, 4 super bionik fertilizer ml/l water, 4 ml super bionik fertilizer/l water, and super bionik fertilizer 5 ml/l water. Each treatment was replicated 3 times. Data were analyzed using ANOVA and HSD at 5 %. The research results showed that the application of super bionik fertilizer significantly increased plant height and leaf number but no significant effect on the number of buds. The application of super bionic fertilizer at concentration of 4 ml/l water showed greater plant height and number of leaf than the other concentrations.

Abstract

The research was carried out at the Laboratory of Plant Disease, Faculty of Agriculture, Tadulako University.  A various number of Trichoderma spp tablets was diluted into 10 ml of sterilized water in accordance with the treatment dosages, namely 1, 2, 3, 4, 5, 6 and 7 tablets to form suspension. Each Trichoderma spp suspension mixed with P. palmivora suspension (3 ml) were invested into 30 g of soil, then incubated for 0, 3, 6, 9, 12 and 15 days.  As much as 5 g of the soil was inserted into a hole made on cacao and incubated for 3, 6, 9, 12, 15 dan 18 days in a series.  Then the size of spotted area on cacao was observed in accordance with the day of incubation period. The research result indicated that the treatment of 4 tablet Trichoderma spp has the largest inhibiting power (99,99%), but it was not significantly different with the treatments of 5, 6 and 7 tablets.

Abstract

The  experiment on cocoa-pod husk processing by soaking it in KOH solution and fermenting    it with Saccharomyces sereviceae was conducted to study its effects on ruminal concentration of total VFA and ammonia in Kacang goat. The study was carried out with a 2x4 factorials randomized design. The first factor was soaking treatment (soaked in KOH solution or not soaked), while the second factor was 4 levels of Saccharomyces sereviceae concentrations (0, 5, 10, and 15%). Each treatment was repeated three times. Responses of soaking treatment on parameters observed were analyzed with a t test while those of Saccharomyces sereviceae levels were tested with a polynomial orthogonal test. Results indicated that there were no interactions between the soaking treatment and concentrationa of Saccharomyces sereviceae in affecting parameters observed. Concentrations of rumen VFA increased with increasing levels of Saccharomyces sereviceae. Soaking in KOH solution increased rumen fluid VFA concentration, but decreased that of rumen ammonia in Kacang goat
