Pengaruh Parameter Proses Freis Terhadap Kekasaran Permukaan Baja Karbon Fasa Ganda

Dual phase is a new structure at low or medium carbon steel. The structure is obtained from the heating of low or medium carbon steel in the region α + γ (temperatures between A1-A3), then follow by holding process within a certain time and cooled quickly (quench) in water,brine or oil. The result has a microstructure of martensite and ferrite as well as a few otherstructures. The steel usually has high tensile strength, good elongation and there is no discontinuity yield. The problem is how the influence of parameters milling process on surface roughness the dual phase carbon steel The purpose of this study was to determine the outcome Freis CNC cutting conditions due to the formation process of double and tempering phase that begins with the process of forging (forging) on carbon steel .This study used AISI1045 steel Ø16mm x 150mm diameter, which was forged at a temperature of 950oC-900oC to form a rectangular cross section with a size of 10mm x 16mm x 180mm. Dual-phase heating was continued at a temperature of 770ºC, arrested at 90 'and cooled rapidly in oil , followed by atempering process 600⁰C/30 '. The process of cutting was done by cutting finishing with feeding 0.12; 0.14; 0.16 mm / put and depth of cut 0.4; 0.6; 0.8 mm while roughing cuts by feeding 0.2;0.4; 0.6 mm / put and depth of cut 1.2, 1.4;a1.6amm .The result Depth of cut can affect the deflection. The deflection could be increased by increasing the depth of cut. The results obtained increase the level of surface roughness. On the depth of cut 0.4 mm with feeding 0:16mm / put the value obtained average roughness Ra 0.64 μm, including group N6 roughness when compared with 0.8 mm depth of cut with the same feeding value of average roughness Ra 1.08 μm including N7. Surface roughness increased by feeding could affect the feeding of 0.12 mm / put and 0.16 mm / put, 0.2 mm / put and 0.6 mm /put because the distance from the cutting peak roughness increases, so the roughness of the rough and the process of finishing cuts on carbon steel dual phase is more subtle than on the untreated carbon steel with the same cutting parameters

Performa Reproduksi Udang Pisang Domestikasi Non-Ablasi Fenneropenaeus indicus

The aims of the study were to evaluate the reproductive performance of pond reared broodstock of Fenneropenaeus indicus without prior ablation for shrimp maturity. These technique being reported impair physiological process and finally offspring quality Pre-maturation was with (BFT) and without biofloc technology (non-BFT) system assessed during the trials. First trial, amount of 10 months old broodstock were acclimatized during four days before mating, while the second trial a total of 190 pairs shrimp at 11 months olds  were culture separately (females and males) during four weeks and reared into biofloc system prior maturation performed.  Molasse was used as carbon sources to maintain C/N ratio of 15:1. All maturation processed conducted using rectangular cement tanks at 10L and 14D condition. Shrimp fed on fresh diets consists of squid, oyster and live Nereis sp ca. 25% body weight (1:1:1). Daily water exchange rate of 100% in the morning and afternoon, respectively. It was found that the latency period from the trials (6-7 days) within the ranged of common intervals for F. indicus. However, daily spawners, nauplii production and postlarvae survival  shows any significant differences (p<0,05) were 8.0% vs 11.4%;  33.850 vs 51.246 N spawner- and 30.7% vs 23.26%, respectively. Results finding shown that domesticated F. indicus can successfully produced healthy post larvae without prior broodstocks ablation. Study on BFT during pre-maturation of these species firstly report and there is the need for further research in terms of pre-maturation period, nutritional status of the broodstock, and compensatory growth in ponds
