[Computation and modeling] The current solar cell technology is a technology developed by a process that is cheaper and easier in manufacturing. The solar cells sensitized by a dye below abbreviated writing that the DSSC is often also called Grätzel cells or whether the writing in Indonesian to be Sel Surya Berbasis Pewarna Tersensitisasi (SSPT). DSSC is a potential candidate in as a third generation of solar cells (coming soon) because it does not require a material with a high degree of purity so that a low-cost production process. Dye used as a sensitizer can be either synthetic or natural. Metal-based organic dye complex ruthenium using synthetic (it is expensive), but it contains heavy metals that harm the environment. To reduce the cost of DSSC develops organic based on material sensitizer. DSSC using the same principles for the process of photosynthesis that behave as a chlorophyll dye that absorbs light and produces carrier.The effectiveness of DSSC is no doubt that reaching more than 10% but with using this expensive type which is ruthenium complex metal-based organic. It is necessary to study massive research, a material awareness survey that has good performance, environmental costs.

Abstract

Post-harvest apples are still doing the metabolism process such as respiration and transpiration that lead to decreased fruit quality so that required post-harvest handling, one of them with the waxing process. Wax detection on fruit is difficult to do directly, so further testing is required. One method that can be done is to use optical technology is a speckle imaging system with the LSI (Laser Speckle Imaging) method that is without touching (non-invasive) and without damage (non destructive). The apple contrast value before lamination has a contrast value in the range 0.34637 a.u until 0.38449 a.u. After waxing the apple contrast value decreases. Apples with 4% wax concentration had a contrast value 0.319 a.u, with 6% wax concentration had a contrast value 0.3109 a.u and with 8% wax concentration had a contrast value 0,29895 a.u.
