Abstract

Peroxidase activity of the hybrid poplar Populus x canescens (Ait.) Sm. (= P. tremula L. x P. alba L.) inoculated with compatible and incompetent isolates of Paxillus involutus (Batsch) Fr. was investigated. Screening of the ectomycorrhizal fungal isolates was initiated with exploration of mycelial growth characteristics and mycorrhizal ability in vitro with poplar. Both traits varied within the fungus although they did not seem to be genetically correlated. While isolates SCO1, NAU, and 031 grew faster than others, only isolates MAJ, SCO1, and 031 were able to form ectomycorrhiza with poplar. Isolates MAJ (compatible) and NAU (incompetent) were subsequently selected for further experiments. Activity of peroxidase, one of the defense-related enzymes, was examined in pure culture and short root components of compatible and incompetent interactions between poplar and P. involutus. Peroxidase activities increased significantly in poplar inoculated with incompetent isolate of the fungus compared to control, while induction of the same enzyme was not detected in compatible associations. Key words: ectomycorrhiza, Paxillus involutus, peroxidase, plant defense, poplar

Abstract

Populations of Aedes aegypti in South Kalimantan, which have been discriminated by their cuticular components, were further studied in search for differences in their wing morphometry. Female mosquitoes were collected from five towns in the province of South Kalimantan, and Cartesian coordinates of terminal and branching points of individual wing were determined. Relative interpoint Euclidean distances were used as variables (characters) in statistical analyses. One-way ANOVA found significantly several different characters (P < 0.01). Stepwise discriminant analysis using these characters selected five discriminators which, by cross validation, could identify female A. aegypti from Barabai and Marabahan with 75 and 77.8% of success rate, respectively. On average, 57.7% of wing specimens were successfully allocated to their original populations. The study revealed differences in wing measurements among populations of A. aegypti in South Kalimantan and confirmed genetic divergence of the species in the province. Key words: Aedes aegypti, wing morphometry, discriminant analysis, identification, discrimination

Abstract

This paper focuses on what religion is, cultural traditions and civilization and their relationship and obstacles in civilization. Religion as a teaching revealed by God as a guide for humans for the continuation of their life. Religion is also a regulatory norm for its adherents which in daily life is indispensable for sustainability in the future. Because without religion, their life will be chaotic, especially if social activities or social traditions are very complex, this is very much needed. Tradition is a habit that has been carried out from the past, this is done so that the tradition is maintained from one successor to another, while civilization is an end result that is done by humans themselves, both materially and immaterially. This study is a literature review with qualitative descriptive data using content analysis, which produces data that there is a very close relationship between religion, cultural traditions and civilization. Religion is very closely related to traditional culture itself because in culture there are elements, one of which is religion. Likewise, civilization is also closely related to religion because one aspect of human life will not be separated from the rules (religion) itself. Because civilization is the result of the creation of cultured humans themselves.

Abstract

In designing, developing, and delivering instructional materials, both for face to face apd written or mediated instruction there are some important principles that should be considered. Among the principles are the contextual teaching and learning (CTL) and the instructional message design principles. The contextual teaching and learning principles consists of relating, experiencing, aplying, cooperating, and transferring. The instructional message design principles consists ofreadiness and motivation, attention directing devices, repetition, student's active participation, and feedback. To get effective instruction, those principles should be imple­ mented and integrated to the instructional strategy components whichconsists ofpre instructional activities, presenting information, eliciting performance, providing feedback, testing, and follow up activities (transferring, remedial, and enrichment). Key words: Contextual teaching and learning, instructional message design, instructional strategy components.

Abstract

This article is based on an evaluative research intended todetermine the quality profileof the educational radio programsproduced by PUSTEKKOM DIKBUD, a center for communicationtechnology for education, from the pointof view of instructionalaspects, the popularityof the media, and the listeners' level ofunderstanding.Thirty-two pre-recorded educational programsin the format ofaudiocassettes were selected for field evaluation/testing. For thepurposeof the field evaluation, sixty elementary school teachersfrom three provinces (Central Java, Central Kalimantan,and EastNusa Tenggara), with twentyfrom each province, were selected assubjects for the field evaluation. For three days, each group oftwenty teachers were assigned to listen to 10- I2 of the radioprograms. After listeningto each program, they were asked to fill outa questionnaire and interviewedin order that information of theiropinions, impressions, and understandingof the programs could beobtained.The findings show that in general the qualityof the radioprograms from the pointof view of their instructional aspects wasgood enough (that is, the instructional objectives were clearly stated,the contentsofthe lessons were relevant with the achievement oftheobjectives, etc.). From the pointof view of the instructional media, the programs were interesting (the musical background wasinteresting and the presentations were helpful enough for theunderstandingof the contents of the lessons). Only some of theprograms were considered low in quality and in needofrevision.On the basisof the results of the evaluation, it is suggested thatbefore being broadcast nationally, eachof the radio programs shouldbe field testedto get information about its strengths and weaknessesso that the program developer and producer can revise and improvethem
