Deep sea water (DSW) that was applied to 3 trusses of cultivated tomato for 2 weeks affected fruits properties. However, advantageous effects on the soluble solids content, acidity, and dry matter content of the fruit tend to decline from 1st truss to the successive trusses. Thus it is necessary to study the effect of DSW application when it is applied for longer than 2 weeks in cultivated multi-trusses. In this study, DSW treatment was applied for different durations to obtain effect on fruits development and fruit properties of the 1st to 3rd truss in a 3 truss tomato cultivation system using a nutrient film technique. The results of the study show that DSW treatment has strong effect on fruit enlargement during the stage of rapid fruit growth, which lasts until the fruit almost reaches the final size. Treated plants produced tomatoes with better organoleptic with higher soluble solids content and higher acidity, higher dry matter content, a thicker and more resistant cuticle and also gave higher yields (weight and no of fruits) than in single truss tomato cultivation. Key words: tomato (Lycopersicon esculentum), deep sea water, fruit development, fruit properties, multi-trusses cultivation, nutrient film technique

Environmental biophysics of peatland has high fluctuating by time and its affected on soil CO2 emission. Therefore it is necessary to develop a system for monitoring the biophysical environment and CO2 emissions that can measure continuously to obtain accumulation annual carbon emissions more accurately. The objective of this research was to develop a monitoring system of the environmental biophysics of peatland and CO2 emissions from bare peatlands open. The system of measurement and monitoring of environmental biophysics that have been developed have been able to function properly which includes weather parameters and soil biophysical environment (temperature, soil moisture, and groundwater levels). Carbon emission was measured on an open peat land without vegetation amounting to 62.25 tonnes of CO2/ha/year. Carbon emissions have a positive relationship with soil temperature but has a negative relationship with soil moisture and rainfall.

Economic growth in Bangka Belitung Province is likely to increase. Such improvements have implications on the growing need for fossil fuels from various sectors that cause changes in air quality. Ministry of the Environment recommends doing an inventory of emissions. The load of emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), carbon monoxide (CO), and particulate matter (PM10) is the primary air pollutants dangerous to be inventoried. The average load of SO2 emission Bangka Belitung province of 6,045.89 tons/year and the largest contributor came from the industrial sector (41.43%). Load of NOx emissions by 16,324.84 tons/year, CO amounted to 75,639.01 tons/year, and PM10 amounted to 2,750.66 tons/year. The transportation sector is the largest contributor of load NOx emissions (62.11%), CO (96.58%), and PM10 (79.93%). The largest contributor of load of emissions SO2, NOx, CO, and PM10 in Bangka Belitung is Bangka. Bangka Belitung Provincial Government planned several strategies to reduce the load of emissions include smart driving, energy audit, centralized power plants, and the conversion of kerosene to LPG in the domestic sector. With the implementation of this strategy is expected to reduce load of emissions by 30%.

AbstractCultivation of tomato plant under hydroponics system in the greenhouse is suitable way to improve fruit quality since it is easier to control environmental parameters. In this system, water and nutrition are two important things for plant to growth. In the tropical area such as Indonesia, air temperature is main constraint in the plant production system. Increasing air temperature inside the greenhouse has positive correlation to the raising temperature of nutrient solution which affected to the ability of the plant to absord the nutrition. The effective way to anticipate increasing of its temperature is by using the cooling system of nutrient solution before circulated to the plant. This paper presented the application of Articificial Neural Network (ANN) to estimate the temperature of nutrient solution which was cooled on day-night time and circulated to the plant. ANN models, called time delay neural network, consist of 3 layers with 4 input nodes and 1 output node. As input model were t (time), Tg(i) (air temperature inside the greenhouse on time i), Tt(i) (temperature of nutrient solution in the tank on time i), Tb(i-1) (temperature of nutrient solution in the plant plots on time i-1) and as output model was Tb(i) (temperature of nutrient solution in the plant plots on time i). The model was developed well with validation result better than heat transfer model previously indicated by coefficient determination (R2) of 0.9498.Keywords: cooling, nutrient solution, hydroponic, tomato, artificial neural networkDiterima: 15 Juni 2010;Disetujui: 30 juli 2010

ABSTRACT A heat transfer model has been developed for a naturally ventilated greenhouse under the tropical climatic conditions. In the tropical region, greenhouses are characterized by high exposure in solar radiation and air exchange through natural ventilation. Therefore in this research, incident angle of solar radiation on the greenhouse roof surface has been considered as an important factor to improve the accuracy in calculating the radiation received by the greenhouse. The heat transfer model consists of four layers represent the cover, inside air, floor surface and soil layers of the greenhouse. The model was applied to a naturally ventilated standard-peak greenhouse. A computer program was developed to predict the temperature of the inside air. Incident angle of direct solar radiation on roof surface and outside microclimate parameters data were used as the input values. Heat transfer equations were solved by using the Runge-Kutta Method while the angle of direct solar radiation with the roof surface was calculated by using the principles of geometry. Results show that the model performed well in predicting the temperature of the inside air as compared to that of the measure value.Diterima: 4 Januari 2007; Disetujui: 26 Pebruari 2007
