Abstract

Cocoa pod borer (CPB, Conopomorpha cramerella  nell.) is a dangerous pest of cocoa which seriously reduce cocoa production mainly in Southeast Asia and Pasific. Prevention of CPB attack can be done by pod sleeving to prevent CPBs lay eggs on pod, or reduction of source of CPB infestation by using pheromone or kairomone as attractant in an insect trap. A preliminary research using sex pheromone has been conducted at endemic cocoa area infested by CPB in East Java. The objective of this study was to evaluate the effectiveness of sex pheromonesin controlling CPB. Trial was arranged by randomized completely block design in four treatments and four blocks as replication. Four densities trap/ha (0, 4, 8, and 12 traps/ha) were used as a treatments. Sex pheromone trap consisted of synthetic pheromone (lure) and sticky liner was hanged on 0.5 m above the cocoa canopy. The results showed that the number of CPB captured during four months was significantly decreased. The number of CPB captured per trap during the first two months in the treatment of 0, 4, 8 and 12 traps/ha were 0, 6.5, 4.72, and 5.58 CPBs, respectively. Four months after treatment, the number of CPB captured in the respective treatments was reduced to 0, 0.25, 0.6, and 0.96 CPBs. Estimate calculation on yield loss due to CPB attack showed that before treatment the yield loss ranged 37.4—45.6%, however six months after treatment, the yield loss in treatment plots decreased to 9.4—21%, whereas on control 38.47%. Use of sex pheromones to attract CPB at a density of 4 traps/ha reduced yield losses due to CPB damage by 67.7%. The significant correlation betweenthe number of CPB captured with the damage intensity followed regression equation of Y = - 0,00044X + 0,32059. Use of sex pheromone for monitoring or masstrapping of CPB, as a component in IPM of CPB is promising, due to its nature for specific target, environmentally friendly, effectiveness, and economic values.Key words: cocoa, cocoa pod borer, Conopomorpha cramerella, integrated pest management, biological control, sex pheromone

Abstract

Effectiveness and effiency of CPB control were influenced by the right time of control. To decided this methods, information about CPB infestation was needed. An experiment had been conducted to get a simple and accurate technique for CPB monitoring. The experiment was located in Tirawuta, a smallholder cocoa plantation in Kolaka district, South-East Sulawesi. The evaluated monitoring pods techniques using observing all ripe cocoa pod as standard method, i.e. pod colour changes as an indicator of CPB attack, observation on 100 pods during harvesting, moth trapping and observation on the presence of the holes caused by CPB. The collected data expressed as the percentage of CPB attack and compared with each other. Based on the Chi 2 value and time consumed for monitoring, it could be concluded that the observation of 100 attacked pods during harvesting was the most accurate technique closest to the standard method, with a lowest 2 value and not significantly different to standard method. On the contrary the visual observation on the pod colour showed the less accurate technique with  2 value of 242,25–335,33 followed by the bservation on the present of holes on the pod with  2 value of 243,45–282,87. Furthermore, monitoring technique by moth trapping could not be compared with the other techniques since their unit was unequal. However, no insect could be trapped during a night trapping using either chemical trapping or sticky trap. Development of sticky trap by variation in trap colour could be trapped of CPB moth during more than one week. Red trap was the most interesting (preferred) for the CPB followed by the yellow, white and blue ones. There was significant correlation between number of tree sample and the time needed for observation. Larger size of tree sample consumed a longer time for the observation, but in visual symptom and entry/exit hole observation methods, larger sample size did not significantly influence its accuracy. It’s concluded that both of monitoring technique were not a converge estimation. Key words : Cocoa, cocoa pod borer, Conopomorpha cramerella, Integrated Pest Management, monitoring technique.

Abstract

ABSTRACTThis research was designed to evaluate nutrient digestibility, mentioned as Total Digestible Nutrient of diet containing PUFA (polyunsaturated fatty acid) - concentrate supplemented with yeast and Curcuma xanthorrhiza Roxb for dairy goat. Twenty Ettawah crossbred goat in late lactation were allocated into 6 treatments in randomized block design. The treatments were PD0: PUFA-diet with no supplement, PDA: with Asifit, PDY: with 0.5% yeast, PDC: with 1.5% curcuma, and PDM: with 0.5% yeast + 1.5% curcuma. The PUFA-diet contained of 80% PUFA- concentrate as basic diet and 20% Pennisetum purpureum. While the PUFA sources were roasted ground corn and roasted soybean meal, and corn oil. Results showed that intakes of DM, OM, CP, CF, NFE, ADF, and GE were not affected significantly by dietary treatments. However, EE and NDF among treatments were different significantly (P<0.05), whereas Ca and P were different very significantly (P<0.01). High nutrient contents (DM, OM, CP, EE, CF, NDF, and GE) were found in feces of the goat with curcuma diet (PDC), consequently showed the opposite effects by giving the lowest digestibility (P<0.05 or P<0.01) of these nutrients. Total digestible nutrient (TDN) of PDY and PDM were markedly higher (79.89% and 79.37%, respectively) than that in other diets, such as being the lowest was in PDC (69.94%). This suggested that the yeast concentration of 1.8 108cfu/d, given singly or in combination with 1.5% Curcuma could be considered as the right level for improving nutrient digestibility in the late lactation goat in our study.Keywords: curcuma, dairy goat, PUFA-diet, TDN, yeast

Abstract

The weakness of the Nafion membrane as electrolyte of PEMFC associated with physical properties that is easy to shrink at temperatures above 80°C due to dehydration. Shrinkage will decrease the conductivity and membrane damage. Nafion-SiO2 composite membranes can improve membrane stability. The role of SiO2 in the Nafion clusters is as water absorbent cause the membrane remains wet at high temperatures and low humidity and conductivity remains high. The results showed the content of 2.8 wt% of SiO2 in the Nafion membrane, the conductivity of composite membrane is higher than the pure Nafion membrane that are 0.127 S cm-1 in dry conditions and 0.778 S cm-1 in wet conditions at room temperature. Compared with the pure Nafion membrane conductivity are 0.0661 S cm-1 and 0.448 S cm-1 respectively in dry and wet conditions.

Abstract

This article analyzes the main program for Early Childhood Education (ECE) in the government program in 2009 stated in the President Regulation Number 38 Year 2008. The analysis employs the public policy model by Joko Wiyono, which is an applied analysis descriptive in nature, focusing on the content analysis. The targets are to analyze (1) the main determinant factors, (2) policy contents, and (3) expected and unexpected effects of the policy. The results of the analysis show that the determinant factors have not taken into account of the gap in the ECE implementation, concerns about the discontinuity among types of ECE services, and the development of the kindergarten education discourse. The contents of the program have not made ECE a priority, not all types of ECE services have been developed, and the coordinator of ECE programs has not been explicitly appointed. The objectives of the ECE programs have not set targets quantitatively.   Keywords: public policy analysis, Early Childhood Education

Abstract

 In 2013, the results of UAN for mathematics in primary schools / MI in DIY average value is lower than other subjects, namely Indonesian and IPA. The success of the sixth grade students work on problems UAN is inseparable from the ability of students to understand math at grade material underneath. Based on the experience of researchers, many teachers who have less correct geometry concepts. Of course this is an impact on students understanding of geometrical concepts. So in this study will be examined whether the errors are mostly done by students in grade V on the geometry of the material, especially material area and perimeter of a flat wake. This research is qualitative descriptive field. Subjects were 43 fifth grade students who come from 4 SD / MI in the city of Yogyakarta. Data retrieval by providing written test questions, the essay form. The results showed that the most frequent errors are errors of type-1, which is a misconception. Another error is the fault of type-3, namely: writing mathematical notation and use of the unit.
