German cockroach (Blattella germanica L.), is a residential insect pest and vector of various diseases. To control its population, alternative chemical control models with Fipronil 0.03% are now being developed. Fipronil has been proven to be effective and has no resistance. To increase the effectiveness of the bait in controlling German cockroaches, a fipronil 0.03% combination needs to be developed with a phagostimulant bait of bananas, durian, erythisol sugar, and sugar formulation, so this study needs to be done. This study used an experimental method with a randomized block design (RBD), five treatments such as A: bait with a combination of banana phagostimulant and 0.03% fipronil, B: bait with a combination of durian phagostimulant and 0.03% fipronil, C: bait with a combination erythisol phagostimulant and 0.03% fipronil, D: bait with a combination of sugar phagostimulant and 0.03% fipronil, K: bait with a combination of matrix and fipronil 0.03% (control positive) was used for the interest test, and bait with a matrix without fipronil 0.03% (control negative) was used for mortality testing. The observations the average results for durian, banana, sugar formulated, erytrisol sugar and controls, respectively 20%, 20%, 21.6%, 12.4%, and 22.8%, while the results bait consumed with durian stimulation are 0.29g, banana 0.31g, sugar formulation 0.28g, erytrisol sugar 0.26g and control 0.24g. However, based on statistical tests, the results of the interest test with the feed consumption test between treatments showed no significant difference (p>0.05). The test results in mortality of cockroaches Germany's feed with phagostimulan durian, banana, formulations sugar, sugar erytrisol and control consecutively 98% 100 %, 98%, 98%, and 20%, based on the statistical test there is a significant difference (p<0.05), where the difference based on the Duncan test is their treatment compared to control.

Ikan sidat (Anguilla bicolor McClelland) merupakan ikan katadromous yang sulit matang gonad dalam kondisi budidaya, sehingga perlu dilakukan penelitian untuk mengkaji nilai IKG, IHS, hubungan antara IKG dan panjang gonad relatif ikan sidat hasil budidaya. Tujuan dari penelitian ini untuk mengetahui nilai IKG, IHS, hubungan antara IKG dan panjang gonad relatif ikan sidat hasil budidaya pada ukuran berbeda dan mengetahui korelasi antara IKG dengan Panjang Gonad Relatif ikan sidat hasil budidaya. Penelitian dilakukan dengan metode survei secara purposive random sampling. Sampel ikan sidat sebanyak 29 ekor diperoleh dari pembudidaya ikan sidat di wilayah Cilacap dikelompokkan berdasarkan fase reproduksinya yaitu yellow eel dan silver eel. Variabel yang diamati ialah panjang gonad relatif sebagai variabel bebas dan IKG sebagai variabel terikat. Parameter yang diukur, yaitu panjang tubuh ikan, bobot tubuh ikan, bobot gonad, panjang gonad, dan bobot hati. Hasil yang didapat pada penelitian ini, rata-rata panjang gonad fase yellow eel 16,93 ± 2,09 cm, sementara fase silver eel 19,93 ± 3,46 cm. Rata-rata IKG yellow eel 1,356±0,992 %, sementara silver eel 2,408±1,053 %. Hasil rata-rata IHS fase yellow eel 1,163±0,201 % dan silver eel sebesar 1,339±0,264 %. Analisis korelasi Spearman’s Rank antara panjang gonad relatif dengan IKG didapatkan nilai signifikansi sebesar 0,167 (P > 0,05). Berdasarkan hasil yang diperoleh dapat disimpulkan bahwa Nilai IKG dan IHS Anguilla bicolor McClelland hasil budidaya pada ukuran berbeda memiliki nilai yang berbeda. Tidak terdapat hubungan yang signifikan antara panjang gonad relatif dengan IKG.
