Abstract

Spirulina is a marine phytoplankton that is a microalgae that has great potential in life, one of which is food, because the nutritional coverage contained in this marine phytoplankton includes proteins, carbohydrates, vitamins, minerals, essential fatty acids DHA and EPA so that it can be used as an alternative nutritious food. . The purpose of this activity is to training on inovative snack “Poto Poto Sinjai”, how to make Spirulina in Bongki Village, Sinjai Regency. The method used in this activity consisted of a location survey and the production of snack from Spirulina . The implementation phase of the activity using counseling methods and training on the benefits of Spirulina as nutritious food and making snack Spirulina. The results of the implementation of this activity were the increase in participants' knowledge about snack Spirulina, as a highly nutritious snack. The results of the knowledge improvement test show that there is a fairly good increase in knowledge of the snack Spirulina innovation products and the results of the organoleptic test show that preference for taste, aroma, texture and color shows good results.

Abstract

The stretch of the Tallo River which stretches across the Makassar city area, and not far from the Makassar Industrial Area, causes contamination of various heavy metals. Some bacteria grow in the presence of toxic properties on heavy metals. The purpose of this study was to obtain bacterial isolates that were able to grow at several concentrations of lead (Pb).Bacteria were isolated by using Nutrient Agar has been added Pb (NO)3 10 ppm. Resistance test was conducted by turbidimetry using a spectrophotometer. Based on research that has been done, the result of isolation of resistant bacteria lead from Tallo River showed that 5 isolates from samples of sediment with code isolates SM3, SM5, SM6, SM9 and SM10, while for the water samples obtained 3 isolates by code isolates AR1, AR2 and AR3. Ability to resist bacteria ie until the concentration of 50 ppm, while the highest growth ability of each different isolates, the highest growth capability isolates SM3, SM6 SM10 and AR3 at a concentration of 10 ppm. SM5 isolates had the highest growth capability at a concentration of 15 ppm. AR2 isolates had the highest growth capability at a concentration of 20 ppm. Isolates SM9 and AR1 has the highest growth capability at a concentration of 25 ppm.
