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.

Between 1992-2005 there were 8 tsunamis occurred in Indonesia. At 17 July 2006 tsunami reached the southern coast of West Java, Cilacap and Yogyakarta. Tsunamis had caused heavy destruction and death.  The aim of the study is to find out spatially the potential of inundation area by tsunami wave based on the distribution of inundation extent of different run up. The run up of 7.5 m flooded 4% from whole study area.  36% of the area was flooded by 15 m run up. When the run up was 7,5 m, some areas were flooded reaching 200 m from the coast and there were also some points going further to 1 km.  The run up of 15 m moved further to 4,5 km. The information on the distance and extent of inundation from some possible run up of tsunami become an input on potential areas flooded by water and having destruction.

High blood cholesterol in human might cause atheroskelerosis, a disease that eventually leads to the occurrence of coronary heart attack. This research was aimed to investigate level of sago waste or shrimp waste on plasma cholesterol and growth in rats. The experiment was conducted on 28 males Spraque dowley rat of one month old and was set up in a completely randomized design with seven treatments and four replications. The treatments were R0 (0 % sago waste and srimp meal) as a control, ASA 10 (10% of sago waste), ASA 20% (20% of sago waste), ASAF 10% (10% fermentation of sago waste), ASAF 20% (20% fermentation of sago waste), LU 10% (10% of srimp waste), LU 20% (20% of srimp waste). Variables measured included feed intake, body weight gain, plasma cholesterol, high density lipoprotein, low density lipoprotein, and triglyceride. The results showed that there was non-significant decrease in feed intake, whereas on body weight gain showed significant effect (P<0.05) between ASA 20%, ASAF 20% and LU 20%. Feed eficiency showed significant effect (P < 0, 01) between R0, ASA 20%, LU 10% with LU 20%. There was significant differences (P < 0.05) in plasma cholesterol between ASA 20% and R0, ASA 10%, LU 10% and 10% of ASAF, while HDL, LDL and plasma triglyceride did not indicate a significant effect between treatment. It  is concluded that percentages of sago waste, fermentation of sago waste and shrimp waste in the ration as an effort to reduce cholesterol do not give a positive effect on feed intake, HDL, LDL and plasma triglyceride of rats; giving 20% of sago waste, 10% of fermentation of sago waste and 10% of shrimp waste showed significant effect on body weight gain, and the highest was obtained at a given ration ASA 20%, i.e. 3.55 g; giving  ASA 20% has the highest feed eficiency  that is  0.31;  giving  20% of sago waste, fermentated sago waste and shrimp waste reduce cholesterol level significantly. The lowest plasma cholesterol was obtained at 20% ASA treatment that is 59.75 mg/dl.

In order to achieve planning consensus, involvement of stakeholders in coastal zone management, have to be concerned.   The participatory prospective analysis (PPA) is a comprehensive and quickly operational framework designed to fulfill the demand for a well-structured effort of anticipation and exploration, that also focuses on interactions and consensus building among stakeholders. PPA was carried out through an expert meeting for coastal zone management planning, as a part of developing system of coastal zone spatial planning, in Lampung Bay. The PPA was aimed to involve stakeholders to generate identification and definition of key variables, definition of the states of variables in the future, building scenarios, and formulation of strategic implications and anticipated actions for coastal zone management. A number of 27 participants from various representative backgrounds, i.e.: local government, fisherman and aqua culturist, local people and entrepreneurs, and local university, was involved in experts meeting. As a result was obtained 6 variables that have the largest influence in coastal zone management of Lampung Bay, they are: quality of human resource, law enforcement, population growth, regional infrastructure, local economic activities, and regional zoning. Consensually, participants was  invented strategic implications and anticipated actions, that have to be accommodated in  coastal zone  management, they are: (1) accomplish requirement of infrastructure and facilities of health and education; (2) develop of micro, small, and medium business (MSMB)  centers  that associated with marine and fisheries; (3) accomplish requirement of housing that comprise proper infrastructure and sanitation facilities; (4) assembly synergy on spatial arrangement among cities  and regencies; (5) assembly spatial arrangement which able to drive development of MSMB in coastal zone; (6) assembly spatial arrangement which able to drive proportional distribution of population in coastal zone, and also proportionally secure the management of conservation and production areas.  Finally, it is concluded that: (1) the PPA could accomplish  direct interactions among  stakeholders intensively and generate consensus opinions; (2) the PPA could be a platform for stakeholders involvement in order to  establish keys variable of planning, define  future states of variables, scenarios building, and strategic implications and anticipated actions for integrated planning of coastal zone of Lampung Bay; (3) stakeholders involvement is the key of  simplification  of policies formulation for  integrated planning of coastal zone of Lampung Bay, in which various of interest could be accommodated.
