Abstract Gurami having economic values of. Have abundance, namely able in waters with its oxygen relatively low. Belong to the species of carnivorous herbs herbivora. Unprofitableness is eat feed derived from herbs with content nutrition relatively low compared to animals, so it impact on its growth slow, easly diseases, easly stress, hard eat and SR low. The purpose of this research isto know the addition of enzyme lignosellulase in artificialfeedincreased growth and increased survival rate seed gourami. Method research used is experimental with delightful random complete (RAL) with five treatment and four deuterenomy. The treatment used were : control (A), enzyme 550ml (B), enzyme 600ml (C), enzyme 650ml (D), and enzyme 750ml(E). The main parameters measured were growth rate, and survival rate. The supporting parameters observedwas water quality. Data analysis used analysis of variance (ANOVA) to know the effect of the treatments.To know the difference among treatments used Duncan’s Multiple Range Test (DMRT). The result showed that the provision of enzymes give a real power (p<0.01) against growth rate daily and growth long absolute gourami (Osphronemus gouramy) To survival rate and feed conversion ratio gourami give impact which is not dissimilar real. Growth best on treatment E (0.0214), then successive followed by treatment D (0.0174), C (0.015), B (0.0142) and A (0.0128). Conversion ratio feed on all treatment e 10,415, that is, e then successive followed by treatment d (12,915), c (14,3975), b (15,6375) and a (17,5325). Survival rate obtained 100%. Water quality media maintenance gourami is temperature 26ºC - 29ºC, pH 7 – 8, oxygen dissolved 3.5 – 5 mg/l and ammonia 0.004 – 0.005 mg/l.

This study aims to determine the rate of growth, survival, and feed conversion ratio in feed of Cyprinus carpio with Hylocereus polyhizus. This study used a Completely Randomized Design (CRD) consisting of 4 treatments and 4 replications. The treatments in this study include 0% (P0), 5% (P1), 10% (P2), and 15% (P3). The method of feeding uses 5% feeding rate with a frequency of three times a day (morning, afternoon, evening). The research parameters observed included survival, specific growth rate, feed conversion ratio and water quality. Quantitative research results showed the best survival at P3 of 92.5%, the best specific growth rate at P3 treatment was 0.04 g / day, the best feed conversion ratio at P3 was 1.06, while the results of qualitative research on water quality showed temperature, pH, Dissolved Oxygen is in optimal condition according to the water quality of koi fish. The conclusion of the 15% treatment study (P3) is the best dose of Hylocereus polyhizus substitution of Cyprinus carpio with increased survival and specific growth rate, and decreases the rate of feed conversion ratio.  Keywords: Cyprinus carpio, Growth, Hylocereus polyhizus, Production, Survival Rate.

The use of Silkworm (Anaphe infracta) pupae as a protein source was investigated for its ability to replace fishmeal in the diet of Clarias gariepinus, African cat fish. Five dried diets formulated at 40% crude protein were fed to fingerlings of an average initial weight of 14.33g at 0 (control diet), 25, 50, 75 and 100% inclusion levels of silk worm meal. The experiment was conducted for 84 days were measured. Mean weight gain (MWG), specific growth rate (SGR), feed conversion ratio (FCR). The five inclusion levels of silk worm pupae supported the growth of Clarias gariepinus fingerlings, the growth and feed utilization were favoured by high inclusion level of silk worm meal. Significant differences (p<0.05) were observed among the treatments, although there were no significant differences (p>0.05) in the growth parameters between 50% and 75% inclusion levels. The 100% silk worm pupae meal inclusion gave the best final mean weight gain of 10.29g specific growth rate of 0.93%, feed conversion ratio of 2.18 and protein efficiency ratio (PER) of 0.012. The carcass protein and lipid contents increased compared to the levels of both at the beginning of the experiment. Even though, there were no significant differences (p>0.05) among proximate composition of the fish groups fed 25, 50 and 75%. The results showed that diet consists of 100% silk worm meal could be used as a complete replacement for fish meal in the diet formulation for Clarias gariepinus fingerlings.

Catfish (Clarias sp.) is a freshwater fish that is widely cultivated because it is a leading commodity. Increased production of catfish resulted in extra area of cultivated land and water use. The technology suitable to be applied is aquaponic system. In addition to saving land and water use, Aquaponic is also improving business efficiency through the utilization of nutrients from food remains and fish metabolism. Water quality is an important factor for the success of cultivation. Maintenance catfish with the addition of probiotics in aquaponic system can be a solution for maintaining water quality, because it contains bacteria that can increase nitrite to nitrate changes that can be utilized for growth of plants and do not poison the fish. The purpose of this study was to determine the effect of different probiotics in the aquaponic system towards growth rate and survival rate of catfish. The method that used in this research is experimental with completely randomized design (four  treat and five repeated) are P0 (control), P1 (probiotic A), P2 (probiotic B) and P3 (probiotic C). Analysis of data processed using Analysis of Variance. If there are significant differences then continued Duncan's Multiple Range Test. The results showed that the giving of probiotics in the aquaponic system is significantly different (p <0.05). The final conclusion is that the addition of probiotics in  aquaponic system affect the growth rate and survival rate of catfish. The highest specific growth rate (0.025%/ day) and the highest survival rate (77.8%) contained in the P2 treatment. The lowest specific growth rate (0.019% /day) and the lowest survival rate (64.4%) contained in P0 treatment (control). Keywords : Aquaponic, Catfish, Probiotic, Growth Rate, Survival Rate, Clarias sp.

Most of the lakes in Indonesia are facing environmental problems such as eutrophication, sedimentation, and depletion of dissolved oxygen. The water quality data for supporting lake management in Indonesia are very limited due to financial constraints. To address this issue, satellite data are often used to retrieve water quality data. Here, we developed an empirical model for estimating the Secchi disk depth (SD) from Landsat TM/ETM+ data by using data collected from nine Indonesian lakes/reservoirs (SD values 0.5–18.6 m). We made two efforts to improve the robustness of the developed model. First, we carried out an image preprocessing series of steps (i.e., removing contaminated water pixels, filtering images, and mitigating atmospheric effects) before the Landsat data were used. Second, we selected two band ratios (blue/green and red/green) as SD predictors; these differ from previous studies’ recommendation. The validation results demonstrated that the developed model can retrieve SD values with an R2 of 0.60 and the root mean square error of 1.01 m in Lake Maninjau, Indonesia (SD values ranged from 0.5 to 5.8 m, n = 74). We then applied the developed model to 230 scenes of preprocessed Landsat TM/ETM+ images to generate a long-term SD database for Lake Maninjau during 1987–2018. The visual comparison of the in situ-measured and satellite estimated SD values, as well as several events (e.g., algal bloom, water gate open, and fish culture), showed that the Landsat-based SD estimations well captured the change tendency of water transparency in Lake Maninjau, and these estimations will thus provide useful data for lake managers and policy-makers.
