Catfish farming is one of the businesses that is very much in demand by the community, because it can improve the community's economy. However, not all catfish farming businesses can produce maximum results. This can be caused by several factors, both from feed, management and water quality. Decrease in water quality can be caused by feces and fish feed residue. Poor water quality can cause the growth process, physiology and level of fish behavior to be disturbed. Efforts that can be done is to use aquatic plants as phytoremediation. The plants used in this study were Azolla sp, Eichhornia crassipes, Lemna sp, Ipomoea aquatic. The design used in this study was a completely randomized design with 4 treatments and 3 replications. The parameters observed in this study were ammonia levels, pH, and plant population. The results showed that Eichhornia crassipes and Lemna sp were able to reduce ammonia levels in catfish cultured water by 0.01 mg/l at the end of the study.Keywords:AmmoniaWater plantsCatfish

This study aims to determine the effect of fermented feed in the form of Indegofera Sp and Eurycoma Longifolia (El) leaves on the quality of Arabian chicken semen. This study used a completely randomized design (CRD) with 4 treatments and 3 replications. The treatments consisted of P.1 : Commercial Feed, P.2 : 80% Indegofera sp + 20% Eurycoma longifolia (El) leaves, P.3: 70% Indegofera sp leaves + 30% Eurycoma longifolia (El) leaves, P.4 : 60% Indegofera sp + 40% Eurycoma longifolia (El) leaves. Semen collection was carried out on day 30 after feeding. The semen quality were observed and analyzed using one-way analysis of variance (ANOVA) followed by Duncan's test. The results showed that the combination of two fermented feed (Indegofera Sp and Eurycoma Longifolia) leaves had a significant effect (P<0.05) on the quality of arab chicken spermatozoa. The fermented feed is able to improve the quality of Arabic chicken semen.

This study aimed to determine the use of fermented cocoa pods to see the growth rate of feed conversion and survival of carp (Cyiprinus carpio). This research was carried out at the Laboratory of the Faculty of Agricultural and Animal Sciences, Universitas Islam Kebangsaan Indonesia using a completely randomized design or (CRD) 4 treatments with 3 replications consisting of A: control, B: 35% fermented cocoa husk + 65% commercial pellet feed, C: 40% fermented cocoa husk + 60% commercial pellet feed, D: 45% fermented cocoa husk + 55% commercial pellet feed. The results showed that the addition of fermented cocoa skin into pellet feed had a significant effect on growth in length, weight, and feed conversion of carp (Cyiprinus carpio) and significantly affected survival where F count > F table.

This study aims to determine the effect of forest bee honey on changes in male sex of sword platy fish (Xiphophorus helleri). The benefits of this study were to determine the appropriate dose of honey for changes in male sex and how the survival rate of sword platy fish larvae was. This study was conducted using a completely randomized design (CRD) with five treatments and three replications, namely Treatment A: Control (Ordinary Feed), Treatment B: Dosage of 3 ml of honey mixed into 100 g of feed, Treatment C: Dosage of 4 ml of honey which is mixed into 100 g of feed, Treatment D : Dosage of 5 ml of honey mixed into 100 g of feed, Treatment E : Dose of 6 ml of honey mixed into 100 g of feed. The results showed that mixing honey into feed gave a significantly different effect on the percentage of male sex ratio where Fcount > Ftable (5.15 > 3.48). Where the best dose is found in treatment E: 6 ml of honey mixed into 100 g of feed with a percentage of 66.05%. While the lowest percentage value is in treatment A (Control) with a total percentage of 40.79%. For the survival rate, mixing honey into the feed had no effect between all treatments. The percentage of survival rates is still in the range above 50%. The range of water quality values ​​is the temperature ranges from 26.55-27.52 0C, pH ranges from 7.02-7.06 and dissolved oxygen ranges from 5.13-5.31 ppm.

This study aims to find out the effect of combination of fermented Indegofera leaf and corn on the growth of Arabic chicken. This study used a completely randomized design (CRD) with 4 treatments and 3 replications. The treatment consisted of P.1: Commercial Feed; P.2: 80% Indegofera sp leaves + 20% Corn; P.3: 70% Indegofera leaves + 30% Corn; P.4: 60% Indegofera leaves + 40% Corn. Measurement of Arab chickens weight was carried out once a week for one month. The weight data were analyzed using one-way analysis of variance (ANOVA) followed by Duncan's test. The results showed that the combination of fermented feed consisting  Indegofera sp leaves and corn had a significant effect (P<0.05) on the growth of Arab chickens. The conclusion shows that fermented feed of Indegofera leaves sp and corn as chicken diet could improve the growth of Arabian chickens.
