Abstract

This study aimed to find out the relationship between the maturity level of female abalone gonads with fecundity and egg diameter size of abalone. The results obtained showed that abalone having gonadal maturity level 1 was in the range of 3-4.5cm; gonadal maturity level 2 in the range size of 4.6-6 cm; and gonadal maturity level 3 in the size range> 6 cm. The results of the abalone gonad histology test showed that abalone with gonadal maturity level 1 had more ootid distribution than the primary oocyte. gonadal maturity level 2 has more ootid distribution, primary oocytes than secondary oocytes. Whereas in gonadal maturity level 3 it appears that secondary oocytes dominate which means the gonads are mature and ready to be spawned. The oocyte diameter is getting bigger and more similar simultaneously with an increasing level of gonad maturity. Abalone with gonadal maturity level 1 has an average oocyte diameter of 187 ?m gonadal maturity level 2 of 190 ?m, and gonadal maturity level 3 of 217 ?m.Abalone fecundity for gonadal maturity level 1 ranged from 60,480-86,190 oocytes; TKG 2 ranges from 196,560-214,520 oocyte grains; and TKG 3 ranges from 483,600-518,880 oocyte grains. Based on the results obtained, it can be concluded that the higher the level of maturity of the abalone gonad, the greater the fecundity with the distribution of more secondary oocytes seen in the results of the gonad abalone histology test.

Abstract

The purpose of this study was to determine the level of water quality in the Pelus River, Purbalingga Regency, Central Java. Water sampling is carried out in the upstream, middle and downstream sections, from June 2019 to July 2019. The water sample was then analyzed for the content of water quality parameters including COD and BOT measured using permanganate-based Titrimetry method, DO is measured using the Winkler method, TSS is measured using the Gravimetric method, then the TDS is measured using a TDS meter, Turbidity is measured using a Turbidity meter, then Nitrate and Phosphate are measured using the Spectrophotometry meth od, and water pH is measured using a pH meter. The results showed an increase in the value of water quality temporally and spatially ie (COD 28-43 mg/L, BOT 8.4-11.3 mg/L, DO 7.3-5.7 mg/L, TSS 32-65 mg/L, TDS 98-168 mg/L, Turbidity 7.2-12.7 NTU, Nitrate 0.8-1.4 mg/L, Phosphate 0.3-0.5 mg/L and pH 6.8-6.6). Temporal and spatial increase in the value of water quality, allegedly due to rainfall and high atropogenic activity in the Pelus River. Keywords: Pelus River; water quality; pollution; Purbalingga

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan tepung udang rebon (krill meal) untuk peningkatan pertumbuhan Ikan Maskoki (Carassius auratus). Penelitian yang dilakukan bersifat eksperimental menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 3 kali ulangan. Perlakuan S0 (kontrol) dilakukan dengan tanpa penambahan tepung udang rebon, sedangkan perlakuan S1, S2, S3, dan S4 masing-masing dilakukan dengan penambahan 5%, 10%, 15%, dan 20% tepung udang rebon (krill meal). Perlakuan dilakukan dengan menambahkan tepung udang rebon (krill meal) pada pembuatan pakan sesuai dengan dosis tiap perlakuan. Pemberian pakan dilakukan 3 kali sehari selama 42 hari pengamatan di Balai Riset Budidaya Ikan Hias Depok. Pengamatan parameter pertumbuhan dilakukan pada awal dan akhir penelitian berupa parameter berat (W mutlak), laju pertumbuhan spesifik, panjang standar (L mutlak), dan efisiensi pemanfaatan. Hasil uji statistik (one way ANOVA) menunjukkan bahwa penggunaan tepung udang rebon (krill meal) berpengaruh nyata terhadap peningkatan pertumbuhan (p<0,05) Ikan Maskoki. Pertumbuhan optimum terdapat pada perlakuan 15% penambahan tepung udang rebon (krill meal) dengan perubahan parameter berat (W mutlak) sebesar 0,58 g, laju pertumbuhan spesifik sebesar 0,44%/hari, panjang standar (L mutlak) sebesar 0,45 cm, dan efisiensi pemanfaatan pakan sebesar 18,37%. Hal ini mengindikasikan bahwa penambahan tepung udang rebon (krill meal) mampu meningkatkan pertumbuhan Ikan Maskoki (Carassius auratus).
