Moth Diversity at Sebangau Peat Swamp and Busang River Secondary Rain Forest, Central Kalimantan HARI SUTRISNO
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

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.

This research aimed to develop a valid and reliable integrated ability assessment instrument (IAAI) to measure the multiple representations and chemical literacy of senior high school students related to the reaction rates. The framework developed in this research was implemented based on a 4-D model (defining, designing, developing, and disseminating). The integrated assessment consisted of five items of essay questions. The preliminary version of the IAAI was initially piloted on reviews by experts, and the paper-pencil test was given to a group of students. The obtained data were analyzed using Item Response Theory (IRT). In addition, Generalized Partial Credit Model (GPCM) model was conducted to examine the parameter quality, which estimated the test items. The content validity, construct validity, and quality of the items suggest that the integrated assessment ability instrument has a high score in validity and reliability. The analysis results of the instrument trial data indicate that the integrated abilities of students are in the medium category.

This study aims to design implementation strategies of DCT in the Basic Inorganic Chemistry course, develop an appropriate course to increase students’ active participation, and develop an evaluation system capable of providing an integrated assessment (both the learning process and outcomes) in the course. This study was conducted in two cycles for one semester during the academic year of 2008/2009. The implementation applied the principles of classroom action research consisting of four stages, i.e. planning, action implementation, observation, and reflection. The data were analyzed by grouping them into categories. The findings were as follows. Qualitatively, the classroom observations showed an increasing active participation of students, both in making the DCT and in conducting discussions in English. Quantitatively, the results of the observations on the learning activities showed an average value of 4 (scale 1-5) for several aspects of DCT.

The objectives of the research are to study of the structure type of titanium dioxide (TiO2) obtained form the ex-situ condensation of hydrated hydrogen titanates with the structure type of lepidocrocite. Hydrated hydrogen titanates were obtained by ion exchabge of H+ for Cs+ in cesium titanates by 1 M HCl solution by Chimie Douce method. The results show that TiO2 (B), anatase, and anatase-rutile mixture were obtained heat treatment of hydrated hydrogen titanate at 100, 200, 300, 500, and 600oc respectively. The powders were characterized by X-rays diffractometer (XRD), High Resolution Scanning Electron Microscopy (HRSEM) and High Resolution Transmission Electron Microscopy (HRTEM). The research indicated that the protonic titanate, H0.54 Ti1.865 0.135O4 0.5H2O ( =vacancy), lost the interlayer water by being heated up to 200oC to produce a dehydrated phase, H0.54 Ti1.865 0.135O4. Above 300oC, the dehydrated phase completely transformed to TiO2(B) and anatase was obtained as pure phase at 600oC. The phase transformed as the following process: H0.54Ti1.865 0.135O4 0.5H2O à H0.54Ti1.865 0.135O4 0.25H2Oà H0.54Ti1.865 0.135O4 à TiO2(B) à TiO2-anatase.
