Melt Loss Dan Porositas Pada Aluminium Hasil Daur Ulang

Aluminum is a lightweight metal, resistant to corrosion, strong, and easy to get, so its use increasing as a basic material. The accumulation of aluminum scrap that not treated properly can pollute the environment, so need effort to recycle aluminum scrap that can be recovered into new products. Recycling aluminum is profitable in terms of economical, because if these metals are extracted from ore of aluminum is very expensive, pollute the environment, consume large amounts of energy and recycled aluminum becomes the cycle that can occur repeatedly without loss of its properties. Utilization recycling is done through the casting process. Aluminum casting process must be carried out carefully to avoid defective products, one of the most commond efect is porosity. Therefore, it needs to do testing to calculate the porosity in order to improve the quality of casting products. The analysis is using materials from recycled aluminum from beverage cans, household appliances, wheels, and the engine block that cast using sand casting method. Comparisons is 1 kg for each casting. Tests were carried out with density test and then perform calculations to determine the porosity and melt loss. The results of the study showed the highest porosity is specimen from beverage cans with 11,94 % of porosity and density value at 2.58 g/cm3, followed scrap from wheels with 2.61 g/cm3 density which 10.92% porosity. For porosity scrap from household appliances and engine block, is 7.16% and 5.64%. As for the lowest percentage melt loss is scrap from wheel with percentage 14%. And the highest melt loss is scrap from beverage cans with percentage 18%

Karakteristik Buah Dan Mutu Morfo-fisiologis Benih Lonkida (Nauclea Orientalis L.) Dari Habitat Alami Di Sulawesi Tenggara

Lonkida (Nauclea orientalis L.) is a native multipurpose tropical tree species in Indonesia, which a few information regarding its biology and ecology. An experimental research was carried out to examine characters of fruit, seed and seed quality of lonkida growing at different habitat in South East Sulawesi. Fruit and seed was collected from four habitat types, such as dry land, permanent swamp, temporary swamp and temporary swamp savanna. The parameters to be observed were fruit size, seed size and morpho-physiology seed quality. The results showed that fruit size and number of seed per fruit are significantly different among habitats. The mean of fruit\u27s length and width and number of seed per fruit originated from permanent swamp and temporary swamp is greater than that of fruit\u27s from lonkida stand growing in the remain habitat\u27s. Those parameters ranging from 4.99±0.17 to 6.66±0.19 cm for fruit length and 3812±519 to 13.984±1912 seed for number of seed per fruit. Beside, the habitat condition also significantly affected to the characters of seed dimension and seed quality. Permanent swamp was a habitat with seed size and seed weight lower compare to another habitats. However, seeds produced by the lonkida stand growing on permanent swamp habitat and temporary swamp savanna has the higher percent of germination, germination capacity and mean day germination (MDG) than that of the seeds from lonkida stand growing on other habitats. Seed length is positively correlated with seed width and negative correlation with means germination time
