Abstract

Cacao plant is one of the major commodity of plantation in South East Sulawesi, especially in Konawe regency.  Practices of land management implemented by the local cacao farmers in many cases are not in accordance to soil and water conservation principles until caused of soil degradation.  The research was aimed to investigate the alteration of soil physics properties on the local farmers cacao cropping land at different slope as related to canopy cover.  The research was conducted in Amosilu Village, Besulutu District, Konawe Regency, the Province of South East Sulawesi, from December 2006 to September 2007.  The experimental method with field study was applied in split plot design consisting of three factors, namely (i) slope consisting of two levels (10-15% and 40-45%) and (ii) age of the cacao plant consisting of two levels (5 to 7 months and 25 to 27 months) were used as main plots (P1 = 5 to 7 months and 10-15%; P2 = 25 to 27 months and 10-15%; P3 = 5 to 7 months and 40-45%; and P4 = 25 to 27 months and 40-45%), while (iii) vegetatif conservation treatment was used as sub plots consisting of three levels, i.e T1 = cacao with disc clearing, T2 = dry field rice and soybean rotation within cacao plant, T3 = T2 + Arachis pintoi as strip plant.  There was not interaction between both cacao plant and slope treatment with vegetative conservation treatment to soil physics properties, exception on aggregate stability index.  The result showed that vegetative conservation treatment (T1) that is cacao with disc clearing was best alternative because they implied the higher rate of total porosity (61,8%) and the lower rate of bulk density (1,013 g cm-3) as soon as the raising of aggregate stability index as well.   Key words: cacao, canopy cover, conservation, soil physics properties

Abstract

The mangrove area of Togean Islands have been used for marine ecotourism activities.  The increasing of anthropogenic activities affected to decreasing of mangrove area and mangrove tourism attractive.  This research aim to assess characteristic and suitability of mangrove forest area for mangrove ecotourism uses.  The data were analyzed using principal component analysis (PCA) and spatial analysis with geographic information system (GIS) approach.  The result showed that the correlation value of those four parameters was relatively higher in November than in July.  Those parameters were the component that forms the main axis in both month. The increasing of turbidity and decreasing of salinity in November rather than in July were correlated with rainy season.  Generally, mangrove area in Togean Islands was suitable with conditional categories to mangrove ecotourism uses.  Ecotourism has the most potential to meet these goals and it will be able to tackle most of the problems when GIS technology would be used as a tool to minimize the impact.   Keywords: area suitability, mangrove, ecotourism, Togean Islands

Abstract

Re-circulating rice dryers suitable for large amount of loading capacity.  It generally comprises of two parts, the tempering section and a drying section, and the grains are dried in an intermittent way until the final moisture content of the grains can be achieved.  Wet grains are initially dried for about 11 minutes within the drying section of the dryer.  The grains then are conveyed to the tempering section where it will be stored for about 40 to 50 minutes.  At every passes, about less than 2%(wb) of the moisture content can be removed from the grains. The number of passes required to accomplish a drying process in a recirculation dryer depends on the initial moisture content and the amount of rough rice to be dried.  The drying and tempering duration can be adjusted by means of a mechanical valve.  The purpose of this study was to examine the performance of re-circulating dryers equipped with pneumatic conveyor instead of bucket elevator to reduce electricity cost and heated using a proper blend between kerosene and jatropha oil.  Several experimental runs had been conducted under a constant drying temperature of 60oC and was controlled by adjusting the rate of fuel consumption.  The experimental results showed that the drying efficiency was in the range of 22.2% to 31.1%, the specific energy consumption was between 3.475-4.785 MJ/kg H2O evaporated, fuel consumption at 0.95 to 1.15 (liters/hr) and the drying rate was 0.9%/hr.  The entire drying operation using 465 kg of rough rice required 10 hours of drying time with 74.3% of head yield.  Mathematical model used in this study also had indicated close agreement with experimental data.   Key words: re-circulating dryer, pneumatic conveyor, drying performance, tempering period, bio-kerosene blend

Abstract

Rice consumption contributes the largest spending among Indonesian. Meanwhile, the changing price of rice is influenced by national inflation. Increased in rice consumption is caused by the increase of population.  It is, therefore, clear that the problem of the rice price increament relates to rice demand and supply.  This research was aimed to analize (1) factors influenced the demand and supply of rice in Indonesia; (2) effectivity of government floor price purchasing policy (GFPPP) vis-à-vis brown rice price policy in frame of increasing rice production; (3) impact of GFPPP on rice demand and supply in Indonesia. The research used time series data ranging from the year of 1981 to 2005. Two stages least square (2SLS) method was used to analyze the data by means of SAS/ETS Version 6.12. It is concluded that the GFPPP increased rice supply in Indonesia. The GFPPP also increased rice price at farmer level and rice production, but decreased demand of the brown rice.     Keywords: rice, supply demand, policy of base price purchasing of government
