Judul: Morphometry and Genetics Diversity of Wild Silk Moth Cricula trifenestrata Helfer (Lepidoptera: Saturniidae).
Abstrak: The study was conducted to describe morfometry, life cycle, fibroin and cytohcrome C oxidase subunit I (COI) gene characteristics of Cricula trifenestrata. Morphometry data were obtained from 3 locations at Campus IPB Darmaga area, namely in the parking area Graha Widya Graduation (GWW), Bara Tomb Complex, and Animal House C Fapet. Observations were done on the duration and timing of life cycle, viability, morphology, anatomy, and nine morphological traits, namely cocoon weight (CW), shell cocoon weight (SCW), cocoon lenght (CL) cocoon width (CWD), pupae weight (PW), pupae length (PL), pupae width (PWD), thorax length (TL), and wingspan (WS). Data were analyzed descriptively, and discriminant analysis were also performed. Molecular data obtained from genomic DNA extracted from silk glands of larvae. Genomic DNA was amplified and sequenced, and then characterized in order to describe the number and type of nucleotide, the number and types of amino acids on proteins fibroin and COI. Characterization results was compared with fibroin and COI genes sequences of other silk moth available in GenBank and using it to constructed phylogenetic tree. The results showed that C. trifenestrata spend 51.0 ± 7.3 days for one life cycle. All morphological traits significantly affected the grouping by location in each stage of development. The prediction accuracy for the parameter grouping cocoon, pupae and imago were 93.6%, 83.3%, and 92.7% respectively, with the biggest differentiator: CV, PW, and WS respectively. The partial fibroin gene consists of first exon coding region with 42 nucleotides (14 amino acids), an introns (113 nucleotides) and partial coding region of second exon with 831 nucleotides (277 amino acids) long. The comparison with other silk moth showed that fibroin gene were conserved on C. trifenestrata, but very diverse with other species. Nucleotides 25th (C), 35th (T) of the first exon, and 12th amino acids (valine) were diagnostic for the species C. trifenestrata. Nucleotide of second exon encoding 277 amino acids that were dominated by the amino acid alanine (27.8%) and glycine (21.66%). Nucleotide introns were very diverse, more than 70% nucleotide of A and T. The partial COI gene of C. trifenestrata size of 595 nucleotides, encoded 198 amino acids. There was no difference nucleotide sequence of intra species C. trifenestrata, but showed 23.7% diversity with other silk moth. Nucleotide dominated by thymine and adenine bases (± 70%). There are 25 nucleotide diagnostic for C. trifenestrata. Sequenced of 198 amino acids, showed only 10% variation between species of silk moth. Amino acid 107th (valine) and 138th (treinonin) are amino acid diagnostic for C. trifenestrata.

Abstrak: The wild silk moth A. atlas L. is being tried for sericulture in Indonesia. The objectives of this research to find out the feeding consumption, the larvae growth, life-cycle, cocoon and filament quality in A. atlas which is raised inside a room. This research was conducted from March 2007 to May 2008. The research comprises two steps: First, analytical proximate castor (R. communis L.) and purging nut (J. curcas L.) leaves; second, silk moth treatment which is done in the laboratory of Molecular Biology PPSHB IPB. The elements used in this research were: cocoon A. atlas and three types of leaves, which are, sirsak (A. muricata L.), castor and purging nut. The research uses Completely Randomize Design. The data resulted is analyzed by Analyze of Variance proceeded by Duncan Tes. The analyzed parameter is feeding consumption, life-cycle, larvae growth, cocoon and filament quality. The total largest food consumption on the larvae feeding on purging nut leaves is 155.09±0.68 g. The increase of larvae’s length and weight is not really present. The shortest life-cycle happen in larvae feeding on castor (60.80±8.37 days). The highest floss and weight decreasing along the cocoon process happens on larvae feeding on castor (66.22±5.85 %) and purging nut (64.53±4.18 %) leaves. The highest cocoon (9.46±1.70 g) and cocoon skin (1.74±0.79 g) weight are on larvae feeding on sirsak leaves. The percentage of cocoon silk does not differ much. The highest cocoon filament length is on the larvae feeding on sirsak leaves (146.84±138.83 m). The cocoon filament weight does not significantly different much. The lowest cocoon distangling capacity is on larvae feeding on castor leaves (12.20±6.65 %). Sirsak leaves feeding on the larvae is superior in filament and cocoon quality, castor leaves feeding on larvae is superior in the fastest life-cycle, and purging nut feeding on the larvae is superior in the largest feeding consumption.

Abstrak: Perkembangan kota Jakarta dari waktu ke waktu sangatlah cepat, sehingga menyebabkan kota-kota tua banyak yang tergusur untuk dijadikan daerah baru yang lebih modern. Apabila hal tersebut tidak ditanggulangi secara dini maka keberadaan Kota Lama Jakarta akan hilang. Hal inilah yang melatar belakang untuk dilakukan tindakan perlindungan dan revitalisasi kawasan bersejarah Sunda Kalapa.
