Judul: Potensi Penggunaan Ketamin sebagai Alternatif Anastetikum pada Transportasi Ikan Patin
Abstrak: The main objective of this study is determining the ketamine potent use as alternative anaestheticum on transportation of catfish. Catfishes were anaesthetized in this study was done by dipping. This study used design randomized complete consist of 6 groups treatment such as P0 negative control without dipping, while P1, P2, P3, P4, and P5 were dipped groups with a dose of ketamine respectively 10 ppm, 20 ppm, 30 ppm, 40 ppm, and 50 ppm. Every treatment was repeated 5 times. The result of this study showed that the fastest onset was P4 group, 26 minutes and the longest duration was P2, 139.12 minutes. The lowest level death was caused ketamine namely P2 groups, 0%. But, the onset of 5 groups treatment wasn’t real diffrence, so could be cloncluded that dose didn’t too influence onset and effective dose for transportation was 20 ppm

Judul: The Potency of Xylzine Utilization as an Alternative Anaesthesia in Transportation of Catfish
Abstrak: This research was conducted to determine xylazine potency as an alternative anaesthesia in transportation of catfish. This research used xylazine as anaestethicum in catfish by dipping method. The research used 650 catfish with body weight about 6 grams and body length about 5 cm. This research used six treatments and five replications. The catfish were divided into 6 dosage groups of xylazine i.e., 0 (as a control), 10, 20, 30, 40, and 50 ppm. The anaesthesia effects were observed as imbalance and less muscle tone, lost of some reflex functions, and also reduced in pain perseption. Dipping with 40 ppm dosage had the onset of 96,2 minutes, the duration of 229,2 minutes, and 0% mortality. Onset and duration of anaesthesia could reflect the effectiveness of xylazine utilization as an alternative anaesthesia in transportation of catfish. The result showed that 40 ppm xylazine was the effective dosage for anaesthesia in transportation of catfish.

Judul: Thermal-Solarimeter Calibration Various Measurements
Abstrak: Sun radiation is a primary energy source for physical atmospheric processes that determine weather and climate conditions. Those sun radiation energy is in the form of electromagnetic wave which if it reaches earth surface, it can change into thermal/heat energy. Thermal/heat energy was measured by “black body” absorbance media , with LM35 as its sensor, and Printed Circuit Board (PCB) as the material. Metal was painted by black coloured pain so that it can be ale to catch the thermal energy well. This research’s aim is to see the efectivity of “black body” absorbance media area size with various diameter sizes, namely, 10 cm, 9 cm, 8 cm, 7 cm, 6 cm, and 5 cm and the relation between “black body” absorbance media area with accumulated thermal. Solarimeter sensor is used as calibrator with its sensitivity15 μV/watt/m, so that 1 mV/watt/m2 equal to 66,7 watt/m2 . The result of this research indicates that that “black-body” temperature sensor with its diameter size 5 cm has the highest effectivity, compared with other sensors. Black-body sensor area is not directly proportionally/liniearly followed by the accumulated thermal. Bigger area size of “black body” absorbance media, bigger accumulated thermal, but it wouldn’be linear.
