Whey waste contains organic materials, particularly high complex proteins and amino acids in the form of suspended and dissolved solids, however the utilization of whey as a organic liquid fertilizer still has a less attention. Thus the Utilization of the whey waste through anaerobic process to be used as a organic liquid fertilizer is the purpose of the research. This research was conducted using factorial design with completely randomized design (CRD) which consists of two factors: the yeast concentration (without yeast; 0.25 and 0.50 g/500 ml of whey waste) and the fermentation time (0, 3, and 5 days). The variables measured were the content of organic C, C/N Ratio, and Total N, P2O5 and K2O contents. The results showed that the fermented whey waste on the different fermentation time and yeast concentration had increased the organic C and C/N ratio, but decreased P2O5 and K2O contents. The utilization of whey combined with solid or other liquid wastes gave a chance to produce a quality organic liquid fertilizer

<div class="WordSection1"><p><em>Catfish farming is strongly influenced by the high price of feed, while azolla is a water fern that has a high nutritional value, can develop quickly and preferably by catfish as feed. The research aims to obtain the most appropriate combination treatment of Azolla inoculum dose and catfish seed size in dual system Azolla - catfish, which is able to provide the highest catfish yield. The experiments were performed in catfish ponds in completely randomized design (CRD) two factors, i,e azolla inoculum doses (250, 500 and 750 gm<sup>-1</sup>) and head circumference size of catfish seed (3, 4 and 5 cm). Dose of catfish seed is 2,000 head / m<sup>2</sup>. Variables observed were azolla fresh weight and catfish fresh weight at harvest. Azolla inoculum and catfish seed deployed together in catfish ponds and feeding with concentrate feed for one month. Azolla and catfish harvesting is done on the same day using a sieve. Once drained, Azolla and catfish were weighed separately to determine the severity. Data were analyzed by F test at the level of 95%, followed by Duncan's multiple range test (DMRT) if any significance influence. The results showed that the higher the  azolla inoculum number,  the higher azolla yield. The larger the size of catfish seed the higher catfish consumption to Azolla. Catfish seed size more than 4 cm will cause an imbalance between the speed of consumption of Azolla by the catfish and the azolla growth rate, so that Azolla be devoured by catfish.</em></p></div>
