ASSESSMENT OF SILKWORM, Bombyx mori (LINNAEUS, 1758) EGG AND COCOON QUALITY AT THE SULAWESI SOCIAL FORESTRY AND ENVIRONMENTAL PARTNERSHIP CENTER, INDONESIA

Abstract

The silkworm broodstock at the production center, strongly influences the quality of silk thread. Therefore, this research aims to determine the productivity and quality of cocoons in five silkworm races ( Bombyx mori L.) at the Sulawesi Social Forestry and Environmental Partnership Center. Five treatments, based on silkworm type, were arranged using a Randomized Block Design (RBD) with three replications per treatment. Data were analysed using Analysis of Variance (ANOVA) and Principal Component Analysis (PCA). The results showed that the best productivity was found in the BN6 type of silkworm for egg hatchability with a percentage of 90.91±2.53%, AJ12 for young silkworm resistance with a rate of 97.98±0.44%, and BN16 for mature silkworm resistance with percentage 38.86±7.12%. Meanwhile, the best cocoon quality is found in the BC117 silkworm type, with the lowest defective cocoon at 3.12±2.21% and the highest cocoon shell at 18.87±0.83%, which is included in the class C cocoon quality range based on SNI 7635:2011 cocoon quality requirements. This research can serve as a basis for management to select the best types of broodstock as superior seeds, which can be developed to enhance the production and quality of silk thread in Indonesia.
