Produktivitas Ulat Sutera (Bombyx mori L.) Ras BS-09 di Daerah Tropis

Abstract

Silkworm is a cold-blooded animal (poikiloterm) so that environment conditions greatly affect their growth. In China, silkworms rearing in the highlands with cool conditions. However, Indonesia is a tropical country with diverse topography conditions and some of them are low altitude areas below 250 m above sea level (asl). This study examined the productivity of silkworms in altitude of 250 m asl. The material used silkworm seedlings from the Silkworm Breeding Center (PPUS) Soppeng and Candiroto, and using 2 different types of mulberry leaf feed (Morus multicaulis and Morus cathayana). Both PPUS have different climatic and altitude conditions. Soppeng at an altitude less than 300 meters asl and Candiroto at a higher one. The results showed that silkworm from Soppeng with fed M. multicaulis was significant different (P<0.05) than other treatments in almost all parameters (consumption, weight of larva, quantity and quality of cocoon shell). The result indicated silkworm Soppeng breed with M. multicaulis have good performance either cocoon shell productions and qualities in Tropic (especially rearing at altitudes around 250 m asl).

Lens on Tropical Sericulture Development in Indonesia: Recent Status and Future Directions for Industry and Social Forestry

“…Hybridization in Indonesia is mostly carried out by the Sericulture Laboratory under the Ministry of Environment and Forestry and Perum Perhutani (a state forest enterprise). There are five silkworm hybridization products that are developed and used in Indonesia: Hybrid C-301 [ 52 , 75 , 77 , 85 ], BS 08 [ 86 ], BS 09 [ 86 ], PS 01 [ 87 ] and SINAR [ 88 ]. Information about silkworm hybridization products can be found in Supplementary Table S1 .…”

“…After obtaining high-quality silkworm eggs, nursery development is needed so they can be commercialized. Until 2012, Indonesia had only two producers of silkworm eggs, namely Pusat Produksi Ulat Sutera/PPUS (Center for Silkworm Production) Candiroto and Kesatuan Pengusahaan Sutera Alam/KPSA (the Natural Silk Concession Unit) Soppeng [ 35 , 86 , 89 , 90 ]. Both institutions are under the management of Perum Perhutani Unit I Central Java (PPUS Candiroto) and Perum Pehutani Unit II East Java (KSPA Soppeng).…”

“…Both institutions are under the management of Perum Perhutani Unit I Central Java (PPUS Candiroto) and Perum Pehutani Unit II East Java (KSPA Soppeng). The production of these two nurseries results from the silkworm hybridization that has been carried out, namely C301 [ 52 , 75 , 77 , 85 ] and BS 09 [ 86 ]. The following conveys the productivity of silkworm eggs in Indonesia and the institutions that produce them ( Table 2 ).…”

“…Hybrid C301 is a silkworm strain widely used in various environmental conditions [ 39 ]. Silkworm eggs from two different nurseries reared in the same place sometimes resulted in different productivity [ 35 , 86 ]. Rahmathulla [ 92 ] confirmed that seasonal differences in the environmental components significantly affect the genotypic expression in the form of the phenotypic output of silkworm crops, such as cocoon weight, shell weight, and cocoon shell ratio.…”

Utilization of Cricket (Gryllus bimaculatus), Black Soldier Fly (Hermetia illucens), Mealworm (Tenebrio molitor), and Silkworm (Samia ricini dan Bombyx mori) as Alternative Feed Protein Sources

“…Tepung BSF umumnya digunakan sebagai pakan babi, ayam petelur, ayam pedaging, dan burung puyuh (Wardhana 2016), demikian juga dengan ulat hongkong. Ulat sutera juga telah dikembangkan untuk menghasilkan sutera dengan kokon sebagai produk samping yang digunakan dalam usaha kerajinan (Estetika & Endrawati 2018).…”
