Abstrak: Jatropa curcas seed meal (JCSM) is by product of biofuels that contains high crude protein (24.6%). However, the utilization of JCSM as feed ingredient is limited by the presence of antinutrients factor, such as curcin and phorbolester. This antinutrients could interferes body protein synthesis. Detoxification is needed to optimize the meal utilization. The purpose of this study was to evaluate the effects of feeding fermented JCSM using Rhizopus oligosporus on follicle and giblets of quails. The research used 150 of 9 weeks of age quails and were reared during 7 weeks. The treatment diets were BJ0 (diet without JCSM), BJ3 (diet containing 3% fermented JCSM), BJ6 (diet containing 6% fermented JCSM), BJ9 (diet containing 9% fermented JCSM), and BJ12 (diet containing 12% fermented JCSM). The parameters observed were follicle (quantity and weight), the weight percentage of giblets (liver, heart, gizzard, spleen, proventriculus, small intestine, colon, and ceca), and length percentage of intestine. This experiment used Completely Randomize Design with 5 treatments and 3 replications. The data were analysed using Analyses of Variance (ANOVA). The results showed that feeding fermented JCSM up to 12% significantly (P < 0.05) decreased the quantity of the follicle.

Abstrak: The major problem in broilers industry is feed availability and continuity. Jatropha curcas L meal is one alternative feed of poultry because it contains high crude protein, but it can not be used properly because of curcin and phorbolester contained in the meal that interfence the protein synthesis in the body. The present study was conducted to study the effect of feeding fermented Jatropha curcas L meal in the diet on feed consumption, body weight, body weight gain, feed conversion ratio and mortality. The research used 96 Day Old Chicks (DOC) Ross strain which were reared for five weeks. The treatment diets were: R0 (0% fermented Jatropha curcas L meal), R1 (3% fermented Jatropha curcas L meal), R2 (6% fermented Jatropha curcas L meal) and R3 (9% fermented Jatropha curcas L meal). This research used Completely Randomize Design with 4 treatments and 4 replications, each replication contained 6 broilers The data were analysed using Analyses of Variance (ANOVA). The significant results were further tested using Duncan's Multiple Range Test. The research result indicated that feeding fermented Jatropha curcas L in starter and grower-finisher period at the level of 3% (R1), 6% (R2) and 9% (R3) highly significantly reduced (p<0.01) feed consumption, body weight and body weight gain compared to that of control diet (R0). Feed conversion ratio in starter period at the level of 6% (R2) and 9% (R3) highly significantly increased (p<0.01) compared to that of control diet (R0). The mortality of broilers at starter period indicated that feeding Jatropha curcas L at the level 9% (R3) highly significantly increased (p<0.01) mortality compared to that of control (R0). At grower-finisher period indicated that feeding Jatropha curcas at the level 6% (R2) and 9% (R3) highly significantly increased (p<0.01) mortality compared to that of control (R0). Detoxification Jatropha curcas L with fermented using Rhizopus oligosporus has not effective yet to improve the broiler performances.

Abstrak: An automatic detector of water level with sensor UGN3505 as detector of changes water level has been successfully be made for this research. Sensor UGN3505 is a hall effect sensor which works based on the large magnetic fields on the surface. The output voltage generated by the sensor without the influence of a magnetic field is 2,525 volts, the output voltage is different than it should be 0.025 volts is 2.50. This shows that the sensor is not completely free from magnetic field sources, there is still the effect of the Earth's magnetic field to the sensor. Sensor output voltage will increase, with increasing magnetic field on the surface of the sensor. As the central data processing equipment, used microcontroller ATmega16. The input of microcontroller is the changes output voltage of sensor than has been converted into digital data (internal ADC ATmega16) caused the changes of magnetic field. The digital data are readable by microcontroller be processed and displayed in the 16x2 LCD, LED indicator and buzzer. Programs created using software tools CVAVR with C + + language.
