Abstrak: Budidaya ikan patin (Pangasius sp.) memiliki kendala pertumbuhan lambat untuk mencapai ukuran konsumsi. Salah satu bahan yang dapat digunakan untuk mempercepat pertumbuhan ikan adalah thymol. Tujuan penelitian ini mengevaluasi suplementasi thymol dosis berbeda (0%, 0,1%, 0,2% dan 0,3%) pada pakan dengan masing-masing empat ulangan, selama 60 hari terhadap kinerja pertumbuhan ikan patin. Benih ikan patin yang digunakan memiliki bobot 2,12 ± 0,03 g dan panjang 6,61 ± 0,03 cm. Ikan dipelihara di waring berukuran 2 x 1 x 1 m3 dan ketinggian air 50 cm dengan kepadatan 30 ekor m-3. Hasil penelitian menunjukkan nilai biomassa akhir ikan patin yang diberi pakan dengan suplementasi thymol 0,3% lebih tinggi dibandingkan perlakuan kontrol (p<0,05), namun nilai laju pertumbuhan spesifik, tingkat kelangsungan hidup dan hepatosomatic index tidak berbeda nyata. Pemberian thymol dosis 0,3% dapat menurunkan nilai rasio konversi pakan, retensi lemak, retensi protein dan protein efficiency ratio lebih tinggi dibandingkan dengan perlakukan kontrol (p<0,05). emberian thymol dengan dosis 0,3% pada pakan dapat meningkatkan kinerja pertumbuhan ikan patin., Catfish (Pangasius sp.) cultivation has a slow growth constraint to reach consumption size. One of the ingredients that can be used to accelerate fish growth is thymol. The aim of this study was to evaluate different doses of thymol supplementation (0%, 0.1%, 0.2% and 0.3%) in feed with four replications for 60 days on growth performance of catfish. The catfish seeds used have a weight of 2.12 ± 0.03 g and a length of 6.61 ± 0.03 cm. Fish are reared in the waring measuring 2 x 1 x 1 m3 and the water level is 50 cm with a density of 30 m-3. The results showed that the final biomass value at a dose of 0.3% was higher than the control treatment, the specific growth rate, survival rate and hepatosomatic index were not significantly different from the control treatment (p>0.05), the administration of thymol dose was 0.3%. can reduce the value of the feed conversion ratio and significantly different fromother treatments. Fat retention at a dose of 0.3% showed a higher value compared to other treatments besides that the protein retention value and protein efficiency ratio at a dose of 0.3% were higher than that of the control treatment (p <0.05). Giving thymol at a dose of 0.3% in feed can increase the growth performance of catfish

Judul: Growth Performance Of Striped Catfish (Pangasius sp.) Fed With The Addition Of Astaxanthin
Abstrak: Penggunaan astaxantin pada pakan mempengaruhi kinerja produksi pertumbuhan ikan patin (Pangasius sp.). Penelitian ini bertujuan mengevaluasi penggunaan astaxantin pada pakan terhadap pertumbuhan ikan patin. Perlakuan dalam penelitian ini, menggunakan empat perlakuan (K, LP50, LP100, dan LP150) dan tiga ulangan dengan masing-masing dosis (0, 50, 100, dan 150 mg kg-1) yang diberikan pada ikan patin dengan rata rata bobot awal 7,16 ± 0,01 g sebanyak 15 ekor per akuarium dengan ukuran 90x45x45 cm dan ketinggian air 30 cm. Setelah masa pemeliharaan selama 60 hari, bobot biomassa akhir tertinggi diperoleh perlakuan LP100 sebesar 359,50±2,52 g sedangkan bobot biomassa terendah pada perlakuan kontrol sebesar 305,70±4,92 g. Hasil penelitian menunjukkan bahwa parameter kinerja pertumbuhan (biomassa akhir dan bobot individu akhir) pada ikan patin yang diberi astaxantin menunjukkan hasil yang berbeda nyata (p<0,05) terhadap ikan patin dengan perlakuan kontrol. Berdasarkan hasil dari penelitian ini penggunaan dosis terbaik terhadap penambahan astaxantin pada pakan yaitu 100 mg kg-1 pakan., The use of astaxanthin in feed affects the growth production performance of striped catfish (Pangasius sp.). This research aims to evaluate the use of astaxanthin in feed on the growth of catfish. The treatments in this study used four treatments (K, LP50, LP100, and LP150) and three replications with each dose (0, 50, 100, and 150 mg kg-1) given to catfish with an average initial weight 7,16 ± 0.01 g for 15 fish per aquarium with dimensions of 90x45x45 cm and a water level of 30 cm. After a maintenance period of 60 days, the highest final biomass weight was obtained by the LP100 treatment, amounting to 359.50 ± 2.52 g, while the lowest biomass weight in the control treatment was 305.70 ± 4.92 g. The results showed that the growth performance parameters (final biomass and final individual weight) in striped catfish treated with a dose of pink lucantin showed significantly different results (p<0.05) compared to striped catfish treated with the control treatment. Based on the results of this research, the best dose to use for adding pink lucantin to feed is 100 mg kg-1 feed.

Abstrak: Land slide or soil movement is one of geological disaster caused by natural or unnatural factors. The impact of this disaster is very damaging for environmental or social economics aspect. Hence, this disaster is needed to monitor because it's event can be suddenly. From January until August 2008, Indonesia has been experiencing 300 times of natural disasters, at least of 263 lives have lost because of this. Natural disaster consists of landslides, floods, earthquakes, etc. There were 1.927 people heavily wounded, 66.988 minor injuries (Depkes, 2008). There were 192.221 people should be evacuated in West Java because the province was one of the most affected. LIP1 researcher (2008) reported that "land movement" in 71% of FFTest Java mostly caused by 58% landslide and 16% landslide which followed with faults. One of landslide mitigation activity is mapping of landslide vulnerability on a national and regional scale.
