The problem in the sea cucumber culture development in Indonesia is the difficulty to find the culture area that could provide optimal production. This study analyzed the habitat type that could provide optimal growth and proximate and energy content to sandfish Holothuria scabra maintained in different habitats. The study was done from March to June 2011 in the Puteangin Island, Lasitae Village, District Tanete Rilau, Barru Regency, South Sulawesi. The cage size used was 2 m in length, 1 m in width, and 1.5 m in height. The net mesh size was 0.5-inch. The cage placed at three different habitats, i.e. the sandy and seagrass habitat, sandy and coral habitat, and sandy habitat. The study consisted of three treatments and three replications. Growth was observed by measuring the daily specific growth rate and absolute weight growth. Proximate and energy content of sandfish was analyzed at the beginning and the end of the study. The study reveals that the sand and seagrass habitat provide the best results with daily specific growth rate is 1.15% ± 0.03%. The absolute weight growth is 28.45 g ± 0.95 g. The proximate content is 0.24 g ± 0.492 g for protein, 0.07 g ± 0.395 g for fat, and 18.026 g ± 0.39 g for carbohydrate. The highest energy content is 176 997 calories.
