The development of lightweight flat sheet prototype from para rubber leaves and para para rubber wood fly ash for field work application can offer an alternative method of adding value to agricultural wastes and help to conserve the environment with green products. The natural fiber especially agricultural waste fiber is an encouraging prospect. Natural fiber composites have been used for building applications. The aim of this research was to investigate the potential use of para wood ash to producing a cement composite as an environmentally material. Material. The cement paste with 5-2 % weight of para wood ash. The specimens were cured at 25± 2 oc for 24 hours. The properties of cement composites mixed with different proportions of para wood ash were compared with Ordinary Portland Cement (OPC). In addition the morphology of para wood ash was examined by using scanning electron microscope. The density increased with the increase in the percentage of para rubber leaves from 1% 2% 4% and 6%. The finding is attributable to the enhanced packing density by the fine para wood ash particles size was found 5-10 um.Moreover para wood ash particles could arrange to fill the inter-particle voids in cement pastes which resulting to increase the compressive strength of cement paste. Consequently para wood ashes could incorporate in the construction materials to enhance the mechanical properties and durability performance of the cement composites

Springback behavior is a major problem of sheet metal forming process. Especially aluminum alloy which often encounter such problems often. At present aluminum alloy is increasingly of used in the automotive industry for replace of the steels due to its lightweight and good finished surface. This work aims study to springback behavior of cold rolled aluminum alloy (AA6016) during air-bending process by ISO7438/2010 test standard. To analyze the influence of bending process parameter are included: sheet thickness punch radius bending angle die open and the ratio of bending radius and material thickness (r/t) effecting to springback behavior. The results are clearly that the springback angle is likely to increase with increase of the punch radius size of die open and the ratio of punch radius and sheet thickness and the springback tenor to decrease when the sheets thickness and bending angle increased. The increased bending angle will resulted to bending surface region is roughness increase and crack occurred to follow. As a result the bending force and the springback angle decreased.

This research project has developed and produced natural fiber-reinforced cement tiles by incorporating natural fibers from para rubber leaves and torpedo grass and mixing them with cement and then compressed into a mold with dimensions of cube was 5 cm x 5 cm x 5 cm. The ratio of fiber and cement were 1:9 2:8 and 3:7 respectively. This study used both types of natural fibers including para rubber leaves and torpedo grass. This research found that torpedo grass mixed with cement in a ratio of 1:9 provided high quality of reinforced cement. The density of this sample was found 2.07 g/cm3. Moreover the dry shrinkage value and water absorption were 0.02% 0.10% respectively. The compressive strength was 64.25 kN or 0.23 MPa. In comparison with the standards of non-load bearing concrete blocks according to TIS 58-2530 the result shown that some experimental data are lower than criteria standard. Furthermore the adhesives (i.e. silica) are very important for the quality of natural fiber-reinforced cement

The study on baked crispy okra sheets (Hit 9701 species) by using a hot air dryer. The objective of this study was to investigate the okra sheets formula and manufacturing procees by hot air dryers with 3 methods; pouring finely blended okra onto the inside tray pouring finely blended okra onto the outside tray and pouring finely blended okra into an aluminum block. It was found that pouring finely blended okra into an aluminum block resulted in the least crack in the dried sheet with the rectangular shape remaining intact. After the forming method is decided on a study was conducted on the temperature to bake okra at 3 levels namely 70 80 and 90 C.It was found that baking okra at 80 C for 4.5 hours was suitable the baking and crispy okra sheets ended up with the lightness(L*) of 49.75 the green (a*) was-2.53 and yellowness (b*) of 23.71. The moisture content was at 5.07 % water activity content was 0.27 The hardness was 5.01 N and the crispness was 4.67. The results of chemical analysis showed that the carbohydrate content was 76.34% crude fibers was 10.72% ash content was 8.24% moisture content was 4.24% and fat content was 0.46%. From the study on the bacteriological quality it was found that the crispy okra sheet products can be stored at room temperature for 28 days.

The aims of this research is to study the suitable ratio of substituted okra with star gooseberry by standard recipe of Production of Crispy Okra Sheet by Hot Air Oven Dryer (Nipaporn and Arrada 2015) was applied in this product. The ratio between okra and star gooseberry are 50 : 50 40 : 60 and 30 : 70 of total weight then selection and nutritional analysis. Furthermore to study using drum dry and belt drier as a prototype for small and medium enterprise (SME). The result showed that the ratio between okra and star gooseberry at 40:60 (w/w) was the highest score of appearance color flavor taste texture and overall liking. The seasoned star gooseberry baked sheet product had total Energy 3 7 2 .0 9 and Energy from fat 47.61 kilocalories/100 gram. Protein Fat Carbohydrate Ash and Moisture content were 14.70 % 5.29 % 66.42 % 7.83 % and 5.76 % respectively. The using belt drier for being dried at 170 oC for 42 minutes was the optimize condition for as a prototype for SME in the future.
