Cooling is the best preservation method than others because the food that has been cooled will remain fresh and will not experience a change in taste, color and aroma, besides all the activities that cause decay will stop so that the cooled food will last longer. (Hartanto, 1984). With the proper cooling engine planning, it can help with spatial adjustments, adjustments to loading, estimation of the power to be used, and budget plans. That is what is commonly called the cooling load calculation. Calculation of cooling load needs to be carried out before planning. This is necessary because the magnitude of the pending load is very influential on the selection of the cooling engine so that the freezing point for preserving food can be accurate. Pendiginan burden is influenced by external and internal factors. With the experimental method, it is obtained the results of the external cooling load as the external cooling load is 11.6 kW, the inner cooling load is 138.8 kW and the performance work coefficient (COP) is 2.

The scope of this study relates to the reconstruction of the Sunda ethnic clothing, especially in Bandung marvelous fashion with the intention to reinvest the values of local wisdom Sundanese culture. On Sunda marvelous fashion reconstruction used an experimental method with the following stages: a. Making fashion design Menak Sunda, b. Selection of materials/ material, c. Manufacture of clothing Menak Sunda/ Bandung. Experimental method used to reintroduce a form of fashion Menak Bandung to the public. The results showed that clothing menak Sundanese source can be found in museums Prabu GESAN Ulun is Menak Clothing Bandung. Reconstruction fashion Menak also functions as a medium in instilling the values of local wisdom of Sundanese culture, especially related to the fashion area of Indonesia. Clothing is a cultural phenomenon in a culture, because it is through the visual language/ visualization of clothing, it can be studied, explored and revealed the values contained therein. It also can be a communication medium that has a historical past and the meaning of positive values for the local culture then submitted at the present or future.

The study was conducted over two months, from March to April 2012. This study aims to analyze the influence of type of packaging materials for durability of chilli (Capsicum annum L.) during cold storage. The method used in this study is an experimental method using a completely randomized design (CRD), which consists of four types of packaging materials, namely of chilli are packed in plastic PE, PP, PS, PS + control film with a red pepper that is stored without packaging. The parameters analyzed are severe shrinkage and the organoleptic (texture, color, aroma and overall). From the test results obtained ANAVA Fhitung value of 203,869 is greater than the value Ftabel, both at the level of 5% for 3,480 and 5,990 at 1% level. For the organoleptic value of PS + plastic film gives the highest yield in each test the texture attributes of 6,678. 6,500 color, aroma and overall 6,122 and 6,722. PP plastic gives the lowest result in each test the texture attributes of 3,156, 3,556 color, aroma and overall 3,333 and 3,300, this indicates that there is a very significant effect between the type of packaging materials for durability chili during cold storage.

(1) Background: Tocochromanols are a group of fat-soluble compounds including vitamin E (tocopherols and tocotrienols) and plastochromanol-8, and just one avocado can contain up to 20% of the required vitamin E daily intake. (2) Methods: HPLC and LC-MS/MS analyses were performed in avocados of various varieties and origin for the identification and quantification of tocopherols, tocotrienols and plastochromanol-8. After selection of the variety with the highest vitamin E content, we evaluated to what extent short- (4 h) and long-term (10 d) cold storage influences the accumulation of tocochromanols. (3) Results: Analyses revealed that “Bacon” avocados (Persea americana Mill. cv. Bacon) were the richest in vitamin E compared to other avocado varieties (including the highly commercialized Hass variety), and they not only accumulated tocopherols (with 110 µg of α-tocopherol per g dry matter), but also tocotrienols (mostly in the form of γ-tocotrienol, with 3 µg per g dry matter) and plastochromanol-8 (4.5 µg per g dry matter). While short-term cold shock did not negatively influence α-tocopherol contents, it increased those of γ-tocopherol, γ-tocotrienol, and plastochromanol-8 and decreased those of δ-tocotrienol. Furthermore, storage of Bacon avocados for 10 d led to a 20% decrease in the contents of α-tocopherol, whereas the contents of other tocopherols, tocotrienols and plastochromanol-8 were not affected. (4) Conclusions: It is concluded that Bacon avocados (i) are very rich in α-tocopherol, (ii) not only contain tocopherols, but also tocotrienols and plastochromanol-8, and (iii) their nutritional vitamin E value is negatively influenced by long-term cold storage.

This study selects nine indicators impacting on project management pattern selection of post-disaster reconstruction projects. Questionnaire investigation is carried out based on the nine indicators and the needed data for this study is collected. Using factor analysis method, the nine indicators are classified into three main dimensions, which are internal factors, external factors and project goals. Correlation analysis between three main dimensions and six project management patterns is conducted to find the key dimension affecting each management pattern selection. According to the above analysis process, this study provides a selection flowchart of post-disaster reconstruction project management pattern, which may provide a new way for post-disaster reconstruction project pattern selection.
