Tingkat keberhasilan siswa dalam mempelajari kimia selain dipengaruhi oleh kemampuan penguasaan konsep dan kemampuan pemecahan masalah, ada faktor lain yang dapat mempengaruhi yaitu faktor psikologis siswa seperti afiksasi diri. Tujuan penelitian ini adalah untuk mengkaji afiksasi diri siswa pada penerapan model pembelajaran pemecahan masalah berbasis representasi multipel dengan model pembelajaran pemecahan masalah pada materi kesetimbangan kimia. Penelitian ini merupakan penelitian kuasi eksperimen dengan Posttest Only Design. Sampel dalam penelitian ini adalah dua kelas siswa kelas XI MIPA pada salah satu SMA yang diambil menggunakan teknik Purposive sampling. Kelas eksperimen (26 siswa) diajarkan dengan model pembelajaran pemecahan masalah berbasis representasi multipel sedangkan kelas kontrol (24 siswa) diajarkan dengan model pembelajaran pemecahan masalah. Instrumen yang digunakan untuk memperoleh data dalam penelitian ini adalah instrumen angket. Data yang diperoleh, kemudian dianalisis dengan menggunakan uji statistik parametric. Berdasarkan hasil uji Independent t-test diperoleh nilai signifikansi sebesar 0,002 < 0,05. Sehingga dapat disimpulkan bahwa terdapat perbedaan afiksasi diri siswa antara penerapan model pembelajaran pemecahan masalah berbasis representasi multipel dengan model pembelajaran pemecahan masalah.ABSTRACTThe level of success of students in studying chemistry is not only influenced by the ability to master concepts and problem-solving abilities, there are other factors that can influence, namely students' psychological factors such as self-efficacy. The aims of this study were to examine students' self-efficacy in the application of multiple representation-based problem-solving learning models with problem-solving learning models on chemical equilibrium material. This research is a quasi-experimental study with Posttest Only Design. The sample in this study were two classes of students of class XI MIPA at a high school who were taken using purposive sampling technique. The experimental class (26 students) was taught with a problem-solving learning model based on multiple representations while the control class (24 students) was taught with a problem-solving learning model. The instrument used to obtain data in this study was a questionnaire instrument. The data obtained were then analyzed using parametric statistical tests. Based on the results of the Independent t-test, it was obtained a significance value of 0.002 < 0.05. So, it can be concluded that there are differences in student self-efficacy between the application of multiple representation-based problem-solving learning models with problem solving learning models.

Publisher : Bogor Agricultural University, Indonesia

A study on moth fauna with focus on macro-moths was conducted at Gunung Halimun-Salak National Park from January to December 2007. The aims of the study were to acquire information of macro-moth diversity and to access the composition of the species at this area. Another objective of the research was to explore undescribed species of moths that inhabit this park. The result showed that a year collecting time with four sampling sites recorded only about 86% of estimated value in this park (846 of 983 species). Index diversity based on Fisheries ? is high. In addition, the number of families recorded from this park is also high, 29 families, or about half of the moth families that occur in Indo-Malayan region. Citiis site was the highest among other sites in term of the diversity index, while Gunung Botol is the lowest. These two sites have a few species in common. In general, Geometridae, Noctuidae, and Pyralidae dominate across all sites. The other significant finding of the research is that Dudgeonidae that has never been recorded from Indonesia was found at Citiis site. Key words: diversity, macro-moths, similarity

Molecular Phylogeny of Agrioglypta Meyrick and Talanga Moore (Lepidoptera: Crambidae; Spilomelinae) Inferred from Nuclear EF-1a Gene HARI SUTRISNO
HAYATI Journal of Biosciences Vol. 12 No. 2 (2005): June 2005
Publisher : Bogor Agricultural University, Indonesia

The phylogeny of the two closely- related genera, Agrioglypta Meyrick and Talanga Moore, was inferred from nucleotide sequence variation across a 973-bp region in the nuclear elongation factor-1 (EF-1) gene. Seven species representing the two genera and two outgroup species (Feltia jaculifera Guene and Metallarcha aureodiscalis Meyrick) were analyzed. The results showed the averages of the p-distances in the comparisons between species within genus and between species belonging to other different genera were 3.5% and 4.9%, respectively. EF-1 gene had almost reached saturation at the level of the divergence of these two genera. The phylogenetic analysis using MP and NJ methods showed that each genus was found to be a monophyletic group and the species relationships within each genus were almost consistent as well. A. eurytusalis is the basal species in the genus Agrioglypta. In the genus Talanga, T. sabacusalis lied in the basal node and T. tolumnialis was found to be sister group of T. sexpunctalis.

HAYATI Journal of Biosciences Vol. 12 No. 3 (2005): September 2005
Publisher : Bogor Agricultural University, Indonesia

A study on the diversity of moths was conducted from July to Augustus 2004 at the peat swamp forest Setya Alam research station, Sebangau, Central Kalimantan. The result showed that diversity of moths at this area was lower (100 species of 12 families; H = 6.643, E = 0.794) than that in secondary rain forest Busang River (278 species of 19 families; H = 8.139, E = 0.831). The result also showed that the similarity index (Cj) of the two areas was very low (0.05). Geometridae, Noctuidae, and Pyralidae were dominant in both areas. There might be more species that have not been found during eight night sampling as indicated by the species numbers in both areas has not reach a plateau.

Evolution of a Wingless Gene and its Utility for Inferring the Relationships within Glyphodes Moths HARI SUTRISNO
HAYATI Journal of Biosciences Vol. 13 No. 4 (2006): December 2006
Publisher : Bogor Agricultural University, Indonesia

The evolution of a nuclear Wingless gene was investigated and its utility for inferring the phylogenetic relationship within Glyphodes moths was assessed by comparing with other three genes namely, COI, COII, and EF-1?. The results show that the bias of base compositions in Wingless (C: 0.19) is the lowest among those in COI, COII, and EF-1?. The averages of nucleotide sequence divergences for comparison between groups based on the Wingless were the highest. While substitutions in Wingless and EF-1? genes were not saturated at the divergence of the species groups, COI and COII genes attained saturation at those levels. The phylogenetic analysis based on Wingless solely show that this gene was very useful to resolve the relationships between groups but gave a poor resolution at the specific level, i.e. the relationships within group 1 was not resolved. Combination of all data supports the phylogenetic hypothesis based on morphological data. Glyphodes falls into three species groups: group 2 branched off first then followed by groups 1 and 3. Key words: COI, COII, EF-1?, genes, Glyphodes, mitochondria, moth, phylogeny, relationships, Wingless

Huge areas of diverse tropical forest are lost or degraded every year with dramatic consequences for biodiversity. Human activities such as deforestation, fragmentation, over-exploitation, and monoculture practices are the main drivers of tropical forest biodiversity loss. Investigating of these threats with focusses on changes in species richness or species diversity will be able to minimize any impact of human activities at the early stage in a certain region. Therefore, to know the impact of human activities to dynamic of insect communities in Gunung Salak, West Java, we measured moth diversity and their structure within communities by comparing the index diversity, species richness and species composition across five different habitat types. The results showed that the habitat changes due to human activities had changed not only to the moth diversity but also to their structure within communities. The number of moth species decreased significantly as well as the number of lower taxa (family) in the disturbed forest (secondary forest, Agathis forest, and transition area) within ranges: 20-50 and 10-20%. The composition of the two main families, Geometridae and Noctuidae also showed a major change, family Geometridae decreased within ranges 10-50% in the disturbed area but Noctuidae increased up to 50% in those areas. Indeed, habitat lost due to human activities such as illegal logging, change of land use and land clearing is the main threats to decrease on macro-moth diversity and change their structures within communities.

Notes on Some Biological Aspects of Arctornis riguata Snellen (Lepidoptera: Lymantriidae) HARI SUTRISNO; . SUPUTA; HARI PURNOMO; SISWO POLANDONO; CIPTO WALUYO; ROSICHON UBAIDILLAH; . DARMAWAN; . ISMAIL; IMAN HIDAYAT; NUNUK WIDYASTUTI

Arctornis riguata Snellen is one of lymantriids which attacked a vast range of mango trees in Probolinggo at the beginning of 2011. About 1.2% mango trees from nine sub-districts have been defoliated by the larvae of this species. The larvae of this genus have been reported to forage at Anacardiacea as well; however, they have never been reported to forage at cultivated mango trees in Indonesia. Since there is no biological information of this species, thus, a study on some biological aspects of this species is needed. This study was conducted in the field as well as in the laboratory during 4 months (March-July 2011). The diagnostic characters of this species are black scale at dorsal antenna on both male and female and slightly setae particularly at the costal angle of valve on the male genitalia. Life span of this species is in the range of 30-37 days. This study also found four natural enemies of A. riguata i.e.: Bleparipa sp. (Diptera: Tachinidae), Euagathis sp. (Hymenoptera: Brachonidae), Theronia sp. (Hymenoptera: Ichneumonidae), and Brachymeria lasus (Hymenoptera: Chalcididae). Moreover, a single fungal pathogen of this species also was identified, i.e. Isaria fumosorosea Wize. Having these results, we considered that to control A. riguata, one need to conserve the native natural enemies by manipulating their environment.
