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

Abstract. Indonesia has a high diversity of marine life, including gastropods. The distribution of gastropods varies in various locations at sea such as at the location of seaweed cultivation in Suppa Regency. These types of gastropods have not been identified even though the public knows the benefits of this organism. Therefore, efforts are needed to inventory these types of gastropods. The purpose of this study was to determine Gastropods living together in seaweed aquaculture locations (Eucheuma sp) in Suppa District. This research uses free roaming techniques along the seaweed cultivation location. The population is all types of gastropods that live together in seaweed farming locations. Samples are types of gastropods found at seaweed farming locations. Samples of abiotic and biotic factors along seaweed farming locations are also recorded as supporting inventory data. Gastropods were found there were 9 (nine) types that came from 8 (eight) genera, 5 (five) families. There are 3 species found in all sampling points, namely Cerithidea cingulata, Terebralia sulcata, and Terebralia palustris. Species found in certain locations and not found in other locations are Telecospium telecospium, Faunus ater, Rhinoclavis vertagus, Strombus microurceus, Nerita insculpta, and Monodonta labio. The suggestion of this research is to periodically observe the diversity of gastropod species in seaweed cultivation locations to determine patterns of interaction between organisms and the environment that occur seaweed cultivation locations.Keywords: gastropods, seaweed, pinrang district
