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: 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: Peramalan enso dan pemodelan hubungan enso dengan curah hujan monsoon
Abstrak: Curah hujan merupakan salah satu paramclcr iklim yang sangal bcrpcngaruh dalam bidang pcrlmlim1. Scdangkan ENSO atau El-Nino SouLl1rc11 Oscillation mcrupakan salah satu faktor global yang dapat mcmpengaruhi kcjadian dan pola curah hujan di Indonesia, khususnya wilayah dcngan tipc curah hujan monsoon. Peramalan pola dan nilai ENSO di masa yang akan datang pcrlu untuk dikctahui, schingga variabilitas kejadim1 curah hujan dapat ditindaklanjuti. Dalam pcnclitim1 ini dipclajari pcngaruh ENSO tcrhadap dacrah ·yang mcmiliki tipc cu rah hujan monsoon dcngan dua ta ha pan analisis. (I) Pcramalan ENSO dan (2) Pcmodclan ENSO dcngan Curah Hujan Monsoon. Pcrmnalan ENSO dcngan mcnggunakan mctodc Gcostatistika dcngan pcndckatan intcrpolasi dan ckstrapolasi analisis kcccndcrugan pcrmukaan, mcnghasilkan nilai pcramalan yang cukup baik bila dibandingkan dcngan pcndckatan mctodc Winters dcngan nilai R2 antara 14.57%1, 79.81%, dan ragam pcrmnalan 1.772146 - 5.295013. Karaktcristik model yang dihasilkan mcnunjukkan pola nilai tckanan dan suhu yang ccndcrung mcningkat dari tahun kc tahun bcrikutnya, kccuali tckanan Tahiti yang ccndcrung turun. Hubungan ENSO dcngm1 cuntl1 hujan monsoon untuk kc-crnun stasiun cukup baik bila didckati dengan rcgresi metode !mad.rat terkccil (OLS dan WLS) dibandingkan regrcsi komponcn utama (Principal Component Regression) . Model yang dihasilkan mcmiliki kcmampuan dcm validasi yang cukup b::iik. Nilai-nilai ramalan kc-cnam model yang ada mampu mcngikuli pola dala aktual untuk tmum I 998. Schingga model ini dapat digm1akan scbagai aJtcrnatif lain dalam pcramaJan curah hujan w1tuk kc-cnam stasiun di masa yang berikut..nya.
