In the tropics, when the fruit is going to be cropped, the fruit temperature is same as the ambient temperature. It could reach more than 40 degree Celcius. One of the methods to make the fruit not easily damaged at the post-harvest is by applying the pre-cooling method. It aims to retard the respiration, minimize the vulnerability from the attack of micro-organisms, reduce the loss of water, and reduce the cooling load on the carrier and also the storage system. The fruit thermal conductivity and diffusivity values become the first important data to be recognized in order to determine the precooling time pro-cess to the desired temperature.The research is aimed to recognize the watermelon thermal conductivity and diffusivity values. Modeled as a ball shaped object, the water-melon is chilled in the cooler by natural convection. In the cooling process, the changing temperature in its fruit was recorded in the computer by using IC LM 35 sensors, every 5 minutes. The sensor was set in the ambient, on the fruit surface and in itâ€™s inside with five different radius. There were three of watermelon by weight as 2,590 kg, 3,925 kg and 5,195 kg had been observed.In this research, the calculation of the watermelon thermal conductivity and diffusivity was based on the thermal resistance and capacity formulation. By numerical method, the average value of watermelon thermal conductivity was calcu-lated as 0,438 W/moC. Meanwhile the average value of thermal diffusivity was calculated as 1,137x10-7 m2/s.

Cable channel that serves the electrical energy is the most vulnerable equipment in the installation of security. The occurrence of short circuit in the installation of household is usually caused by bad cable connection or because of damage to cable insulation. To anticipate the damage to cable insulation, required the knowledge of the factors that cause the damage is and how great the influence of these factors on insulation resistance. The effect of temperature can cause the wiring insulation degradation process because it can result in changes in the chemical structure of the material. Degaradasi this process is marked by a decrease insulation resistance, which is characterized by the rapid occurrence of breakdown voltage if the temperature continues to increase. The longer and higher temperature insulation material given the level of damage suffered by the material will also be greater. From the results of testing insulation resistance reduction characteristics can vary from insulating materials d test, depending on the percentage of additive materials are mixed with an insulating material, the degradation process continues over time due to a rise in temperature can cause the wiring insulation becomes stiff and the consequent breakdown voltage to the material will be faster.

Company X is a printing company such as making leaflets, banners, billboards and others. There is a competitors in the region makes the company must continue to increase its productivity in accordance with the development of existing technology in order to have a high level of competitiveness. The existence of competitors in the region makes the company must continue to increase its productivity in accordance with the development of existing technology in order to have a high level of competitiveness.The purpose of this study is to determine the strengths, weaknesses, opportunities, threats (SWOT) and determine performasi companies through content technology assessment (Technoware, Humanware, Infoware, and Orgaware) or THIO.The results showed that the SWOT method internal factors force score the highest points are the location of manufacturing sites is strategically located on the roadsite, the weakness factors is on the highest score of machinery because most existing engines are still using old technology, and opportunity analysis on external factors highest score is the level of technological progress, as well as a threat the highest score is the emergence of new competitors. While THIO obtained from the technological content of each component as follows: Technoware = 0633, Humanware = 0699, Infoware = 0439, Orgaware = 0498. In comparison has been measured also in similar companies in the company Y (as benchmarking) has a value of each component Technoware = 0.801; Humanware = 0.79; Infoware = 0.64; Orgaware = 0.78,.

Currently Open Source software development takes place rapidly with a variety of variations. Support of many people towards Open Source software that is easy to come by, the main attraction that support poppularitas software. One of the Operating System that is popular among programmers in making Web-GIS is MapServer. Web-GIS a system that uses a computer device, to store, process, recall and manipulate geographic data. Using Geographic Information System (GIS) is expected for the users would be easier to know the mapping, GIS mapping for the location of the actual location can be described according to the conditions. MapServer is an example of a fairly successful operating system because it is supported by a community of loyal. By utilizing the Internet Geographic Information Systems Mapping Digital Loop Carrier can be applied using MapServer. Designing Web-GIS created using ArcView application assistance is very supportive in Web-GIS and mapping. Display Web-GIS on the Internet using MapServer and pemetaanya using ArcView, because ArcView is very supportive in the process of digitizing the map.
