Abstract

ABSTRACT The aim of this study was to determine the employment dynamics of agricultural sector in North Sulawesi Province. The research was conducted in Manado (July to August 2010, by using the collecting data as a secondary data research. The data was analyzed using labor share and labor force growth rate.  The result showed that labor share of agriculture sector on the basis of education level was dominated by the level of primary education during the period 2007-2009 but its labor force growth rate had decreased each year in both rural and urban areas. On the age group was dominated by the age of 55 years and above. The  employment growth rate of agriculture sector was decreased by 5.78 percent each year in  the period of 2000-2009. While the fenomena employment in non-agricultural sector was increased by 1.78 percent each year. This result indicated that there was tendency of structural transformation of agriculture sector to non-agricultural sector. The low tendency of trade will be able to influence farmers to reduce or to stop the agribusiness activities that will affect the size of the agiculture labor force share. Keywords: Employment Dynamics of Agricultural Sector

Abstract

ABSTRACT Indonesian indigenous bacterial isolates of B. thuringiensis pathogenic to cabbage pest (C. binotalis) were molecularly characterized and identified using DNA fingerprinting method of ARDRA (Amplified Ribosomal DNA Restriction Analysis). Chromosomal DNA of 10 selected isolates (SLK2.3, SRNG4.2, TKO1, TK9, YPPA1, UG1A, BLPPN8.2, YWKA1, BAU3.2, LPST1) and 2 reference strains (B. thuringiensis serovar kurstaki HD1 & B. thuringiensis serovar israelensis H14) were isolated and purified by standard method. 16S rRNA genes were amplified by PCR method using universal primers of 27f and 1529r. PCR products were digested by 4 restriction endonucleases (EcoR1, HindIII, Pst1 dan HaeIII), and separated by agarose electrophoresis method to generate ARDRA profiles. Results of study showed that only ARDRA profiles generated by Hae III digestion were found to be meaningful and therefore used to identify the isolates. The ARDRA profile analysis indicated that the reference strain of B. thuringiensis serovar kurstaki HD1 could be clearly separated with B. thuringiensis serovar israelensis H14. In fact, those two strains have been widely recognized to be different in terms of their pathogenic specifity against insects. B. thuringiensis serovar kurstaki HD1 has been known to be specifically pathogenic to Lepidopteran whereas B. thuringiensis serovar israelensis H14 has been known to be specifically pathogenic to Dipteran.

Abstract

ABSTRACT The purpose of the research was to studied the application of gliricidia MOL on the growth and yield of lowland rice in the salibu method, and to get the best concentration of gliricidia liquid organic fertilizer  (POC) on the growth and production of lowland rice. Field research has been conducted in Tababo Village, Subdistrict of Belang, district of Southeast Minahasa. The treatment in the experiment consists of one treatment factor, that were concentrations of gliricidia POC, ie  : 0, 50 , 100, 150, and 200 ml/litre. The results showed that gliricidia POC  have an effect on plant height, the number of  grain/panicle, and the dry grain yield (GKP) / plot, but not affect the number of productive tillers and weight of 1,000 grain. The best results were achieved in gliricidia POC concentration 200 ml/litre  with the highest values were: plant height was 98.93 cm; 116.420 grain/panicle; and 8.300 kg dry grain yield or equivalent to 6.92 ton/ha.Keywords : gliricidia POC, production, lowland rice,  salibu method
