Abstract

The objective of this qualitative research is to find out the description of the critical thinking profile of SMP students in solving mathematic problems in terms of cognitive style. To achieve the objective of this research used Group Embedded Figures Test (GEFT) by dividing students into field dependent and field independent cognitive style, mathematic problem, interview and observation. The result of this research shows that: (1) understanding the problem, SAi and SMd are able to identify, collect and analyse the given facts and information clearly and logicaly, (2) make a plan, SAi dan SMd are able to devine the alternative solution in order to solve the problem (3) carrying out the problem, SAi is able to use the alternative problem solution based on his plan systematically; meanwhile, SMd still finds it difficult to use the alternative problem solution based on his implementation plan not systematically. and (4) in the last step, SAi is able to evaluate the obtained result relevantly. Furthermore, he also can give clear argument in testing the obtained result. Whereas, SMd is not able to evaluate the obtained result relevantly, so he can not the given in testing the obtained result.

Abstract

The purpose of this study is to determine the patogenechity (ability to cause death) of the Edwarsiella tarda in fish eel (Anguilla marmorata) which have frozen and stored at a temperature of -25°C for 15, 25 and 35 days. Patogenecity was tested with methode by isolating E. tarda from the meat of frosen Eel that what stored for 15, 25 and 35 days ago carried infected to eels the size of 120-122 grams with injecting isolate bacteria Edwarsiella tarda is intraperitoneally as much as 0,1 ml/ind at a dose of 108 CFU/ml (standard 1 Mac Farland), then maintened and observed for 15 days. Pathogenicity test results based on mortality / death of the fish indicates that the bacteria Edwarsiella tarda taken from frozen eel fish stored for 15, 25 and 35 days at temperatures-25oC were still survive and still are pathogenic to fish eel with a tendency the longer the storage time, it will decrease the mortality rate / patogenitasnya. Results of analysis of variance showed mortality observed eel (Anguilla marmorata) with a storage time of 15 days and 25 days resulted in a significantly different effect than the storage time of 35 days with a storage temperature -25oC.

Abstract

The purpose of this study was to identify and describe the types of arthropods in Gumbasalu cave Bambalamotu District of North Mamuju regency. The result of this study then developed into biology teaching media in the form of a paperback book and audio-visual media. This study was held in form of descriptive research and development using 4D design. Sampling for Arthropods used direct collection techniques and pitffal trap then identified using a key book determination. Results of the study found 16 species of arthropods, which consists of 2 class of crustasea, 6 class of insect, 3 class of arachnid and 5 class of Myriapoda as for the type found is Parathelphusa sp, Macrobrachium lar. F, Rhaphidophora sp, Apis sp, sp Lophobaris, Formica rufa. L, Lepisma sp, sp Antomeris, Heteropoda sp, sp Charon, Heteropoda beroni, Scutigera sp, Scolopendra sp, sp Julus, Nerceus sp, Julus sp. Results were then used as a paperback book and audio-visual media. These two media then validated by the validation results for the paper back book content expert (83.3%), media experts (86.15%), design experts (82.8% ), and audio-visual media experts (93.3%), and then tested on the test results of students with small group for a paperback book (85.2%), testing a large group (86.4%). For audio visual media the percentage result was in a small group (83.51%), in a large group (87.4%). The result of this study shows that learning media in the form of a paperback book and audio-visual is proper for use.

Abstract

Jelly has a supple and elastic texture. Jelly is one kind of product that attracted many people because the texture is different compared to other sweets. One of the factors that affect the quality of jelly is the gel-forming material. This study aims to determine the ratio of seaweed to cow’s gelatin that can produce jelly which has a good chemical and organoleptic quality. The experimental design used in this research is completely randomized design (CRD) with a combination of patterns is a difference ratio of seaweed and cow’s gelatin repeated 3 times so that there are 18 units of the experiment. Chemical parameters were observed consisting of ash and total sugar. Organoleptic parameters were observed consisting of taste and firmness. Jelly that produced in this research had 0.43 to 0.68% ash content and total sugar content 33, -53.67% and it has the organoleptic quality preferred by the panelists. Jelly that produced in this research is still meet the quality standard ISO 3574.2-2008.

Abstract

This studywas conducted Januari to Mei 2015 to evaluate effect of mating method on the pregnancy success oflocal cows in Sigi Regency. The study involved 50 local cows as acceptors. The data were analyzed byusing chi-square method. The observed variables werenon-returnrate (NRR), the conception rate (CR) on thefirst mating, and that average of mating rate requiredto getpregnant.The research result showed that mating method did not influence(P>0.05) on both NRR and NR. The NRR rate were 68% and 64% for artificial insemination and natural mating, respectively. The CR were 64% and 52% for artificial insemination and natural mating, respectively. While service per conception (S/C) for artificial insemination was 1.6 and natural mating was 1.9. It is concluded that the mating method did not have asignificant effect (P>0.5)on the pregnancy success oflocal cows in Sigi Regency

Abstract

This study aims: purple sweet potato tortilla has a crunchy texture. Tortilla purple sweet potato is one of a light meal that is loved by the community compared to other snacks. One of the factors that affect the quality of the tortilla is the ratio of purple sweet potato and cassava. the ratio of purple sweet potato, cassava produce purple sweet potato tortilla with good organoleptic quality. The research is designed using completely randomized design pattern combination and a randomized block design. RAL pattern combination is applied to influence the ratio of purple sweet potato and cassava (F1 = 1: 0), (F2 = 2: 1), (F3 = 2: 2), (F4 = 3: 1), (F5 = 3: 2), (F6 = 1: 1), while RAK applied in organoleptic purple sweet potato tortilla, which was tested by 30 panelists. Organoleptic quality research results purple sweet potato tortilla with panelists color value (5.33), aroma (5.03), flavor (5.97), texture (crispness) with the value (5.33) and the best level of preference is (5.27).
