The purpose of this research was to investigate the population density of Alona sp. on yeast media with different concentrations. The study was conducted using a completely randomized design (CRD) consisting of 5 treatments and 3 replications for 21 days. The treatments given were A: 10 ppm yeast, B: 5 ppm yeast, C: 1 ppm yeast, D: horse manure, and E: well water. The initial stocking density of Alona sp. for each treatment was 15 individuals/300 mL of well water. The water quality parameter measured during the study was temperature. The results of the one-way ANOVA test showed that there were significant differences between treatments on the density level of Alona sp. (p <0.05). Tukey's further test showed that treatment B was the best with a density of Alona sp. as many as 8059 individuals/300 mL of well water. The temperature during the study, in the morning was 26 ± 0.52°C and in the afternoon was 26 ± 0.46°C.

Density Rate

The goal of this research was to observe the effects of yeast on the density rate of Alona sp. with various concentrations compared to the density rate in horse manure media. The treatments are as follows, treatment A yeast 30 mg yeast/0.5 L water, treatment B yeast 10 mg yeast/0.5 L water, treatment C yeast 5 mg yeast/0.5 L water, treatment D yeast 1 mg yeast/0.5 L water, treatment E 0.5 L well water, treatment F horse manure media (horse manure 10 gr, soil 50 g in 0.5 L water). The research was carried out for two weeks, and the density calculation was done once a week. The results obtained based on Anova One Way analysis are that yeast with different concentrations does not have a significant effect on the density of Alona sp. Nevertheless, it was concluded that the giving of yeast to Alona sp. is much more efficient and effective compared to horse manure media, because it is more hygienic, easy to obtain and not expensive, also from nutritional value, yeast has a higher value compared to horse manure media. The measuring of water quality parameter during the research was temperature around 26-30°C.

A 16-week trial evaluated the effects of ethanolic extract of Aspiliaafricana leaf (EeAaL) on the growth performance, carcass and egg characteristics of growing and laying quails. One hundred and eighty (180), one-week old Japanese quail chicks were assigned to six experimental diets (0, 2.5, 5, 7.5, 10% EeAaL or 0.02% oxytetracycline). Each treatment had 30 birdswhich were further subdivided into three replicates of 10 birds. Each replicate was housed in a pen under the deep litter system; feed and water were provided ad libitum.Growth performance and egg characteristics(egg quantity and quality) indices were subjected to the one-way ANOVA in a completely randomized design (CRD). No significant (P>0.05) effect of EeAaL was observed between treatments on the final body weight and daily weight gains of quails. Feed conversion ratio (4.95 – 5.28) was significantly (P<0.05) improved in quails fed 2.5 – 7.5% EeAaL diets. Zero mortality was observed in quails fed 5 – 10% EeAaL diets compared to other treatments. EeAaL supplementation reduced (P<0.05) the amount of fat deposition in quail carcass, thus improving the carcass quality. The efficacy ofEeAaL was more pronounced in laying than growing quails where significant (P<0.05) differences were observed on some external and internal egg characteristics, whereas egg composition did not differ (P>0.05) between treatments. Egg number, hen day production, albumen weight,yolk weight, shell thickness and yolk colour were significantly improved following dietary EeAaL  upplementation, indicative of strong growth promoting and stimulatory effects.Therefore, for improved carcass and egg performances up to 7.5% EeAaL shoud be supplemented intoquail diets.Keywords: Leaf extract, growth rate, egg characteristics, bush marigold, quails

Abstrak: Budidaya ikan badut Amphiprion ocellaris terus dikembangkan hingga saat ini guna menghasilkan ikan badut yang memiliki pertumbuhan, kelangsungan hidup dan kecerahan warna yang baik. Salah satu permasalahan dalam budidaya ikan badut adalah harga pakan yang cukup tinggi. Tujuan penelitian ini yaitu untuk mengetahui pengaruh laju pemuasaan secara periodik terhadap pertumbuhan, kelangsungan hidup dan kecerahan warna ikan badut Amphiprion ocellaris. Metode yang digunakan dalam penelitian ini adalah metode eksperimental dengan menggunakan Rancangan Acak Lengkap yang terdiri dari empat perlakuan dan tiga ulangan, yaitu P1 (tanpa pemuasaan), P2 (1 hari dipuasakan 1 hari diberi pakan), P3 (1 hari dipuasakan 2 hari diberi pakan), P4 (1 hari dipuasakan dan 3 hari diberi pakan) sehingga terdapat 12 unit total percobaan. Data yang diperoleh dianalisis menggunakan uji sidik ragam (One way Anova). Hasil penelitian yang diperoleh adalah pertumbuhan, kelangsungan hidup dan kecerahan warna ikan badut yang mengalami laju pemuasaan secara periodik tidak berbeda nyata (p>0.05) dengan ikan badut yang tidak dipuasakan. Hal ini menunjukkan bahwa ikan badut Amphiprion ocellaris dapat dipuasakan hingga periode 1 hari dipuasakan dan 1 hari diberi pakan yang mengalami total pemuasaan sebanyak 20 hari tanpa menurunkan pertumbuhannya. Pembudidaya ikan badut Amphiprion ocellaris direkomendasikan dapat menggunakan semua periode pemuasaan seperti yang diterapkan pada penelitian ini, namun untuk waktu pemuasaan yang lebih lama diperlukan penelitian lebih lanjut oleh para peneliti.   Kata kunci: Pemuasaan, ikan badut, pertumbuhan, kelangsungan hidup, kecerahan warnaAbstract: Amphiprion ocellaris clown fish cultivation continues to be developed today to produce clown fish that have good survival growth and colour brightness.  This study aims to determine the effect of periodic fasting rates on growth, survival and colour brightness of the Amphiprion ocellaris clown fish. The method used in this study is an experimental method using a Completely Randomized Design consisting of four treatments and three replications, namely P1 (without fasting), P2 (1 day fasted 1 day fed), P3 (1 day fasted 2 days fed), P4 (1 day fasted and 3 days fed) so that there are 12 total experimental units. The data obtained were analyzed using the one way Anova variance test. The results obtained were growth, survival and color brightness of clown fish that experienced periodic mastery rates were not significantly different (p> 0.05) from clown fish that were not fasted.This shows that the clown fish Amphiprion ocellaris can be fasted until a period of 1 day fasted and 1 day fed with a total mastery of 20 days without reducing growth. Amphiprion ocellaris clown fish farmers are recommended to be able to use all periods of mastery as applied in this study but for a longer mastery time further research is needed by esearchers.Keywords: Mastery, clown fish, growth, survival, colour brightness
