Abstract

Microalgae are photosynthetic microorganisms that have potential to produce some useful chemical substances such as carbohydrates, proteins, and lipids. Microalgae are also known exhibited ability as a bioremediation agent. This report is emphasized on analyzing the growth rate and nutritional content of microalgae including carbohydrate, protein and lipid from selected isolates LIPI11-2-AL002 that treated with sago waste. Microalgae were cultivated into hydrolysed sago “ampas” at the concentration of 0,50, 500,5000 ppm, and medium AF-6 (as control culture) respectively.Therefore selected microalgae isolate was cultivated in series of cultivation volume start from 100 mL until 5 Liter media gradually. Observed parameters were covered cell viability (growth) and proximate content of biomass including carbohydrate,lipid and protein content. The results showed that the carbohydrate and protein content in the algal biomass was increase along the addition of series sago “-ampas” concentration.The highest concentration of addition the sago ampas is 5000 ppm which is limit for the algal survival. In the highest treatment of sago waste the alga l proximate contents were 261.09 ppm of carbohydrate, 5.12 ppm of protein and 3.61% per of lipid dry weight respectively. In addition, the toxicity effect of fermentation product was not appeared in a toxicity test using gold fish komet(Carassius auratus).

Abstract

Handling Children Difficulties Learning Dyslexia through Bowling Game Courage aims to find out what is the difficulty of learning dyslexia, its causal factors, its type and characteristics, even to the way to overcome them. The method used in this research using qualitative methods. Children with special needs that vary such as Autism, mental illness, paralyzed, until the children who have trouble learning difficulties are also included in learners who have privileges. A special child is a child who has a weakness in physical function and cognitive to develop well. The cause varies from the disturbance during pregnancy, interruption at the time of childbirth, to the violence in children, it can cause disruption to the learning of children. This weakness is a weakness that can’t be seen with the eyes like wrong at the time of counting, reading and writing. Therefore there is one way to make learners who get problems with learning, especially reading can be helped with the game of letters and numbers, so that children do not feel bored and quickly memorized with interesting games such as bowling games with courage in addition to children can know the letters and numbers, children can also move by following the motion attached to the bowling pin, the child can also count the number of bowling pins that fall, mention the color of the falling pin, then the results of research that has been done from 3 learners who have problems in reading show good results with already able to mention 3 letters. Keywords: Learning Difficulties, Dyslexia, Courage game of courage.
