On this modern era, many people only concern about how to improve the cognitive and psychomotor as the results of their children's education process. They usually did many ways to increasing that aspect but sometimes they forget the affective (attitudes) of their children. The affective aspect, which also known as character building may be interpreted as a series of planned activities conducted by adults to learners; in a purpose the learners may have knowledge and understanding and be able to apply the life values such as goodness, truth and sincerity as their everyday's habits. As the other tribes, Dayak's people in Central Kalimantan also have ways and tools which are functioned in character building, one of which is through traditional art named "Karungut". Karungut is a kind of oral art sung with particular rhymes and accompanied with traditional instrument named "Kecapi". This research aims to describe and analyze the function of Karungut in character building of Dayak's people in Central Kalimantan. The approach used in this research is one to describe and analyze the utterances or opinions of group of people or community, therefore the approach used by the researcher is qualitative. While the kind of ethnographic approach was used considering the objects being described and analyzed is a culture or system of social groups, including mindset, habits, and ways of Dayak's living in Central Kalimantan. Research data were collected using interview and documentation towards source people including: Karungut artists, community leaders, and Dayak's customary leaders. According to the data, the results concluded are: (1) There were 4 (four) functions of Karungut in character education building of Dayak's people in Central Kalimantan, namely: (a) informative function, (b) affirmative function, (c) persuasive function, and (d) prohibition function.
RESUMENous avons etudie le dosage du sulfocyanure de potassium par titrage I'hypobromite. La standardisation de I'hypobromite, solution stable pendant au moins un mois prepark a partir d'un melange adequat de bromate et de bromure, est effectuee par voie iodometrique.La dktermination de differentes solutions de sulfocyanure par addition d'hypobromite en exces en milieu alcalin et titrage de cet ex& par iodometrie (addition d'iodure, acidification et titrage d'iode fornie par le thiosulfate) donne d'excellents resultats avec une prkision de 0,15%.Cornrne 8 electrons sont &changes dans la rkction de I'oxydation de sulfocyanure, les solutions employks ne doivent Qtre que 0,Ol M. De ce fait, la methode proposee se trouve surtout interessante pour la determination de faibles concentrations de sulfocyanure.
RBSUMBLes conditions optimales pour la dktermination de la thio-acttamide par l'hypobromite de soude ont tt6 determhtes. En travaillant dans un milieu de faible alcalinitk, et en employant la methode de standardisation en milieu identique, le nombre d'electrons echangts (n = 8) correspond a la rtaction stochiometrique.Un contrble a dtmontre que la methode proposee a une prtcision moyenne de 0,25%, et permet ainsi des titrages de solutions de thio-acktamide d'une concentration de 0.01 molaire.
