Judul: Eksplorasi Potensi Limbah Imago Ulat Sutera Liar Attacus atlas (Lepidoptera: Saturniidae)
Abstrak: Wild Silkworm Attacus atlas is an Indonesian native germplasm from Aceh to Papua. Cultivation of wild silkworm Attacus atlas has started in line with the high market demand on the caterpillar cocoon. The purpose of this study was to determine the potential of imago waste produced by cultivation of wild silkworm Attacus atlas as a source of alternative feed ingredients and the potency as antimicrobial. Proximate analysis was done to find out nutrition in imago of Attacus atlas, antimicrobial testing using the disk method. The results of the proximate analysis test imago silkworm Attacus atlas shows that the imago contains 75.57% protein, 5.94% fat, 3.80% ash, and 14.64% crude fiber from dry matter. Attacus atlas imago extract is brown, gel, fat as a potential source of animal fat. Antimicrobial test from 96% ethanol extract of imago Attacus atlas with the disk method showed no antibacterial activity against Escherichia coli, Pseudomonas, Streptococcus, and Staphylococcus.

Judul: Performa reproduksi imago jantan ulat sutera liar Attacus atlas L. (Lepidoptera: Saturniidae)
Abstrak: Attacus atlas L. (Lepidoptera: Saturniidae) is one of Indonesian native insect that has a great potential economy. Fulfillment the demand of material for silk thread still rely that exist in nature, therefore, needs to be done with the use of intensive breeding male imago as effective as possible in mating. The aim of this research was to study the reproduction performance of male imagoes of wild silkworm A. atlas. This research was conducted by allow a male imago mate with three different females. The time of each mating was 6 hours. The parameters observed were the first, second and third ejaculate volume, the number of eggs per imago, egg hatching time and hatchability of eggs. The results showed that the frequency of mating significantly affect the percentage of egg hatchability. The optimum value was achieved at first mating was 53.58 ± 18.26%. The percentage of egg hatchability declined with increasing frequency of mating. The number of eggs per imago and egg hatching time was not influenced by the frequency of mating with the average number of eggs per imago 225.86 ± 34.23 eggs and the average time of hatching eggs was 11.20 ± 3.23 days

Judul: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
