Abstract

Several studies have revealed a wide range of beneficial effects of seaweed products applications on plants growth and development. Seaweeds may cause different effect in plant responses because there are a range possible factors acting in concert. These factors may include to the amount of plant growth regulator (PGR) and nutrients present in the products. PGR activity in two seaweed products (Maxicrop® and Seasol®) was investigated using Radish (Raphanus sativus). Treatments included a control, standard concentrations of the seaweed Products (SS1 and MC1), 2 and 4 times the recommended rates (SS2, SS4, MC2 and MC4) ashed seaweed products (SS-ash and MC-ash), and equivalent amounts of N, P and K to that found in seaweed products (SS-NPK and MC-NPK). The results obtained show that both Maxicrop® and Seasol® can significantly increase crop performance. Maxicrop® increased chlorophyll content and root and shoot growth, while Seasol® only increased the chlorophyll content.

Abstract

This study is aimed to determine: 1) The income level of rice farming using SRI method in Ngombol, Purworejo, 2) The allocation of optimal resources of rice farming SRI method in Ngombol, Purworejo, and 3) the effect of changing in input and output prices to optimal resource allocation. The method used is descriptive analysis method with 20 farmers as samples/respondents and implementing interview method using questionnaires. The study was conducted in the village names Ringgit, Ngombol, Purworejo. Study sites was selected by purposive sampling considering that Ngombol is the district with the highest rice production in Purworejo and Ringgit has been long time using SRI method, since 2003. This study were applying: 1) Analysis of the actual farm income, 2) QRP (Risk Quadratic Programming) Model Analysis, and 3) Sensitivity Analysis. The analysis showed that the average production of paddy SRI system A is greater than system B, but for the average cost of system B is higher but for the income system B is smaller than A. This illustrates that SRI paddy farming systems A more advantageous compared to systems B; Optimization analysis results indicate that from the average of the actual land area of 1.81 ha of activity that appears on the optimal cropping pattern farming area system A 1.27 ha and system B at 0.54 ha. Meanwhile, the system A selected as optimal farming pattern with the highest optimal cropping patterns, The results of the optimization analysis also showed that the land and labor resources are still abundant or excessive, where as capital resources are limited. The results of the sensitivity analysis shows that increase and decrease in input prices and output prices both partially and simultaneously for 5-15% do not affect the optimal allocation of resources, but only affects the risk of SRI paddy farming. The increase of input prices is the higher risk faced by rice farmers SRI and other wise higher selling price of output become smaller risk faced by farmers.

Abstract

Central Sulawesi is the first rank of cocoa beans supplier in Indonesia. Unfortunately, climate change resulted on emerging of cacao pests and diseases that causes continuously decreasing productivity of cacao farm. Consequently, farmers have been converted their cocoa farm to others farm. This has been impacted on macro-economy of Central Sulawesi. Generally, the aim of this study is to analyze impact of climate change on macro-economy of Central Sulawesi for case cocoa beans commodity. Particularly, the aim of this study is (i) to analyze impact of climate change on productivity of cacao farm; (ii) to estimate effect of the productivity on GDRP of cocoa beans; (iii) to estimate effect of the GDRP of cocoa beans on macro-economy of Central Sulawesi; and (iv) to estimate trends of macro-economy of Central Sulawesi. Analyze method was econometric simultaneous equation of double logarithm model. Data used was secondary data, 2000 – 2014, namely GDRP of Central Sulawesi, areal size of cacao, production volume of cocoa beans, prices of cocoa beans at farm level. The result of analyze showed that climate change has been impacted on productivity of cacao farm. It was indicated by coefficient of year as a proxy insignificant affect to variety of productivity of cacao farm, so it could be interpreted that the productivity to be constant. Consequently, the productivity couldn’t push up GDRP of cocoa beans. However, GDRP of cocoa beans could still push up the macro-economy of Central Sulawesi. The macro-economy of Central Sulawesi was increasing. Thus, although climate change impacted on the productivity, but GDRP of cocoa beans could still push up the macro-economy of Central Sulawesi. It means that management of pest and disease of cacao farm in a prototype to be important performed.
