Abstract

Unsaturated fatty acid in food has an effect to improve human health, while saturated fatty acid has the opposite impact. Ratio between both types of fatty acids is important to evaluate the biological material for nutraceutical product development. This paper aimed to evaluate the nutraceutical potency of sea cucumber from Kendari Bay Waters, South East Sulawesi, based on their fatty acids composition. The analysis was conducted by the 1H-NMR (Hidrogen-Nuclear Magnetic Resonance) method. Several species within 4 genera (Holothuria, Bohadschia, Actinopyga, and Stichopus) were selected as the subject of the study. Comparison of fatty acid composition has been done in genera level, the preliminary study found that variation between species among the same genera was insignificant (p >0.05). Results of the study detected that Holothuria contained with an even ratio of Poly Unsaturated Fatty Acids (PUFA) and Saturated Fatty Acids (SFA), but Actinopyga was detected with low PUFA/SFA ratio. It may suggest that Holothuria from this region is the most potential raw material for nutraceutical product development. Meanwhile, precaution is needed for genera that contained with low PUFA/SFA ratio. Furthermore, comparison with other studies detected that fatty acids composition is not morphological specific, but vary, according to food viability, environmental and geographic location. Therefore, preliminary screening is important in evaluation of sea cucumber material for nutraceutical product development.

Abstract

 Study on chemical content of swamp fishes from Merauke has been conducted to obtain nutritional status  of these fishes. Sampling was conducted  twice (August and November 2015) in Merauke. There were six dominant fish species, namely striped snakehead (Channa striata), nile tilapia (Oreochromis niloticus), tade gray mullet (Liza tade), philippine catfish (Clarias batrachus), barramundi (Lates calcarifer), and climbing perch (Anabas testudineus). Result on proximate analysis showed that the fishes had moisture content of 75.73±0.25%-81.45±0.04%, ash 0.94±0.01%-1.26±0.21%, protein 17.11±0.09%-18.92±0.05%, and lipid 0.59±0.19%-3.80±0.63%. The dominant essential amino acid of 6 swamp fishes from Merauke was lysine followed by leucine. Meanwhile the dominant non-essential amino acid was glutamic acid (32.26+0.61 mg/g), followed by aspartic acid. Calcium (Ca) was the dominant macro mineral for all fishes studied, being the highest was in nile tilapia (328.76±8.14 mg/100 g). Micro mineral was dominated by the presence of Selenium (Se) which the highest was in nile tilapia (0.084±0.005 mg/100g). These fishes were also rich in albumin, being the highest was stripe snakehead (138.59±1.68 mg/g). The average of total fatty acid showed that the fishes had saturated fatty acid (SFA) content of 46.30±0.27%, monosaturated fatty acid (MUFA) 9.20±1.6%  and polyunsaturate fatty acid (PUFA) 34.49±0.44% of total fatty acid. From the result, it can be concluded that fish harvested from swamp of Merauke and surrounding area had a good nutritional value.

Abstract

This type of research  is a class action research. The purpose of this research enhances students ' critical thinking ability by application of Problem Based Learning with  Audio Visual Media. Data were collected by using a sheet of observation and evaluation tests. The average percentage of critical thinking ability of students overall observation sheet on precyae 13.8% increase in cycle cycle I 69% and increased again in cycle II 96.5%. And the overall percentage on the test results the evaluation cycle I 44.8% increase in cycle II 96.6%. Thus the results showed that the application of problem based learning with audio visual media is able to enhance the critical thinking ability of students.

Abstract

Listening considered as difficult skill and some problems often experienced by the students  which are understanding difficult and new words used by native speakers and connect the meaning into certain message, following the fast speed of speaking of native speakers, understanding different accents and pronunciation of native speakers. Referring to the problems which also experienced by the third semester students of English Education Department at Muhammadiyah Kotabumi university, the researchers conducted a research by applying Research and Development method. The researchers designed listening log-based book as learning source for the students. Forty students became the research subject and the researchers used test and interview to collect the data. The book completed with theories related to material in listening comprehension, some effective strategies to be applied in different listening material and some exercises. The book has been validated, revised and tried out to the students. Based on the result of book try out it was found that the book was effective to reduce learning barrier during listening comprehension course in the class.
