Morfometri Kokon Attacus atlas Hasil Pemeliharaan di Laboratorium

Abstract

Attacus atlas is one of the wild silkworms which is originated from Indonesia, which has economic value and high potency to be developed especially at the cocoon stage. These potential aspects for future developed include row material of silk fabrics, cosmetics, medical, and engineering materials. However, this potential has not been matched by productions level. Attacus atlas still live in nature with only 10% of cocoon production rate. In this study, A. atlas was reared in the laboratory to determine the different characteristics of Attacus atlas cocoon between rearing enviromntment as compared to which in nature. The results showed that the characteristics of the cocoon varies and influenced by humidity and temperature environments, place and behavior during making cocoon. Whole cocoon weight average of 6.37±1.07 g/cocoon, weight of floss (0.23±0.09 g/cocoon or 5.82±3.86%), weight of shell cocoon (0.62±0.35 g/cocoon or 11.

Life Cycle of Wild Silkmoth Attacus atlas L. Fed on Mahogany Leaves and Soursop Leaves

“…Ulat sutra A. atlas L. memiliki keunggulan dibandingkan dengan ulat sutra Bombyx mori karena mampu menghasilkan serat yang lebih panjang yang disebabkan oleh ukuran kepompongnya yang lebih besar. Selain itu, serat yang dihasilkan oleh A. atlas L. memiliki variasi warna alami, mulai dari coklat muda, coklat tua, coklat keemasan, hingga abu-abu (Endrawati & Fuah, 2012). Kepompong A. atlas L. juga dapat diolah menjadi biocompatible film untuk aplikasi medis (Nindhia et al, 2017), dan biopolymer yang memiliki banyak keunggulan dibanding Bombyx mori (Reddy et al, 2013).…”

“…Pengembangan potensi A. atlas L. di Indonesia sudah dimulai sejak tahun 2000-an. Salah satu aspek yang harus diperhatikan yaitu teknik pemeliharaan (Endrawati & Fuah, 2012;Wuliandari & Situmorang, 2002). Rintisan pengembangan A. atlas L. di Kabupaten Banyumas dimulai sejak 2000an (Aprikhani, 2010;Praptiningsih, 2006).…”

Atlas moth (Attacus atlas Linnaeus, 1758) silk sericin protein: The effect of extraction methods and storage time on its content

“…This result was also reported by another study, showed that the crude protein of sericin from atlas moth and B. mori results in protein band ranging from 8.24 to 10.25 kDa for atlas moth, and 8.24 to 8.99 kDa for B. mori. In the same study, the middle silk gland (MSG) of both silkworm species was also used, which resulted in a larger range of sericin molecular weight (Endrawati, 2012). Therefore, it is suspected that direct extraction from sericinsecreting glands is able to isolate sericin that are more diverse in weight, but it is not really practical to do for a large scale.…”

Physicochemical properties of Eri pupae flakes and their antibacterial activity against Salmonella sp., Escherichia coli and Staphylococcus aureus

“…Pupae is a transitional phase in the metamorphosis of a silkworm larva to a moth (imago) (Endrawati and Fuah, 2012). Silkworm pupae are a byproduct of silk fiber spinning that is not generally used and creates pupae accumulation, which is common in the silk fiber spinning industry.…”
