Abstract

The highest decrease in the number of food crop workers occurred in Java, as many as 2,87 million people in 2007-2014. The age of food crop agriculture workers in Java is dominated by workers aged over 45 years (64,95%). If there is no addition of new workers, then the food crop labor will be increasingly dominated by old age groups which will make it difficult for the agricultural sector to carry out its mandate to improve and maintain sustainable food security. The purpose of this study is to describe the condition of the food crop agriculture subsector from the aspect of labor absorption in Java for the period 2007-2014 and analyze the effect of the regional GDP of food crops subsector, real wages, education, and land area to the absorption power of agricultural food crops subsector on labor in Java. Central Java Province is a province with the largest decrease in the number of agricultural food crop subsector workers compared to the other four provinces on Java island. From the results of the estimation, the fixed-effect model with cross-section SUR is chosen as the best model. The results show that the variable of regional GDP, real wage, and size of land area has a significant and positive effect on the labor absorption of agricultural food crops subsector, while education has a significant and negative effect. Overall this model able to explain variations of this phenomenon by 89,32%. Meanwhile, another 10,68% is explained by other variables not included in the model.

Abstract

The need for soybean increasing every year causes soybean imports to be done continually, so an effort to increase the production must be done to reduce dependency on imported soybean. This study aims to determine the characters that can be used as an indicator of selection to increase soybean yields. The study was conducted in the village of Sa'atu, Coastal Poso Subdistrict, Poso Regency, Central Celebes Province, from January to April 2011. Using a randomized block design (RBD) with 30 genotypes (varieties) as the treatments that were repeated 3 times, so it obtained 90 units of experimental plots. The observed variables were plant height at harvesting time, flowering age, harvesting age, number of pods per plant, number of seeds per pod, number of productive branches per plant, total weight of pods per plot, weight of 100 seeds and yield of seeds. The results showed that plant height at harvesting time, harvesting age and number of seeds per pod have genetic variability coefficients that were moderate while the other traits were high. The number of pods per clump and the number of seeds per pod have moderate heritability values while the other traits were high enough. Harvesting age has a significant negative genetic correlation with the yield while the number of productive branches, total weight of pods per plot and weight of 100 seeds have significant positive genetic correlations with soybean yields. Weight of pods per plot is a trait that has high direct effect on and significant positive correlation with the yields so it can be used as an indicator of trait selection to improve soybean yields.

Abstract

One of problems in the Jabon propagation is the availability of seeds both quality and quantity. Tissue culture technology is one of the alternatives that can be used for the supply of Jabonseeds to produce organs of plants (buds, leaves, roots). The success of plant tissue culture techniques is determined by the condition of explants, a supportive environment and the addition of growth regulators are expected to provide a response to the cultured explants. This study aimed to know the effect of Benzyl Amino Purine (BAP) and Indole Acetic Acid (IAA) to in vitro multiplication of Jabon. This research conducted at the Laboratory of Forestry Sciences, Faculty of Forestry, University of Tadulako from March to May 2015. Using a completely randomized design with treatments: 0.1 mg / l IAA + 1 mg / l BAP (JB1), 0.1 mg / l IAA + 1.5 mg / l BAP (JB2), 0.1 mg / l IAA + 2 mg / l BAP ( JB3) and 0.1 mg / l IAA + 2.5 mg / l BAP (JB4). Each treatment was repeated three times to obtain 12 experimental units. The results showed that the difference in response Jabon of treatment tested was the highest number of buds and leaves were in the media added 0.1 mg / l IAA + 1.5 mg / l BAP. Furthermore, the formation of callus obtained in media which added 0.1 mg / l IAA + 1 mg / l BAP.

Abstract

Cassava commodity has strong linkages with other industries. This is indicated by coefficient of its multiplier effect being greater than one. That means that investment of IDR 1 billion for the commodity will affect total economic activity of Central Sulawesi as big as the coefficient. The aim of this study is to estimate potentially competitiveness of cassava commodity of Central Sulawesi in international trade. In particular, the aim of this study is to estimate (i) potentially competitive advantage of cassava commodity; (ii) potentially comparative advantage of cassava commodity; (iii) level of governmental protection to price of tradable input for cassava; (iv) level of governmental protection to cassava outputs; and (v) level of simultaneously protection to cassava output sand tradable inputs for cassava. PAM method was used by using time series data of during 2000 – 2013 from BPS and FAO. The results of analysis shows that cassava commodity from Central Sulawesi has potentially competitiveness in international trade. This is showed by (i) potentially competitive advantage was indicated by PCR is less than one; thus cassava farm can be developed on a large scale; (ii) potentially comparative advantage was indicated by DRC is less than one; This means that in developing for cassava farm can be done by saving the resources; (iii) NPCR is equal to zero to show that government policies to tradable inputs is very protective, but actually that was caused by farmers didn’t apply fertilizers and pesticides; thus developing for cassava farm can be done by organic farm, so cassava farm can be became as entry point in green economy of Central Sulawesi; (iv) NPCO is less than one meaning that government policies for output prices is in-protective, so cassava farmers didn’t enjoy actual prices of cassava output; and (v) EPC is less than one meaning that beside government policies for prices of cassava output is in-protective, government policies for tradable inputs is also in-protective; thus although the farmers didn’t enjoy the surplus prices, however they can pay tradable inputs being lower than actual prices of the tradable inputs.
