Abstract

Reptile skin is covered with scales that form a protective barrier, making it waterproof and enabling life on land. The present study investigated the histological structure of the skin of the Python reticulatus and Varanus salvator. The samples used were Python reticulatus and Varanus salvator skin taken from the dorsal region. Preparations were made using the hematoxylin eosin (HE) staining method which was carried out at the Microbiology of the leather processing technology, Politeknik ATK Yogyakarta. The results showed that the histological structure of Python reticulatus skin consisted of two layers, epidermis and dermis. The epidermis was composed of stratum corneum, stratum granulosum, and stratum basale. The dermis consists of an outer layer called the stratum laxum (stratum spongiosum) and an inner layer called the stratum compactum. Meanwhile, the histological skin structure of Varanus salvator skin consists of epidermis which included oberhautchen, α-keratin layer, β-keratin layer, supra basale layer, and basale layer. The dermis consists of superficial dermis and deep dermis. There are differences between Python reticulatus skin that is distinguished by its ability to ecydis (skin shedding) the epidermis and Varanus salvator skin have osteoderm (OD) within their dermis layer

Abstract

This study aimed to help reduce the lime fleshing solid waste problem by implementing utilization as feed for Black Soldier Fly (BSF) larvae. The BSF larvae were analyzed as a sample to determine whether it is safe to be eaten by other living species, especially catfish. The raw material used is lime fleshing cowhide waste from a leather tannery. The process included fermentation of lime fleshing waste with a formulation of waste: bran: water (8:1:2) for three days, hatching BSF larvae eggs for six days, and feeding fermented waste to BSF larvae (1000:1) for nine days, then baby BSF larvae dried, and BSF larvae were applied to catfish in a ratio (BSF larvae weight = 9: 5) for 12 days. Then, they analyzed the protein, calcium, and sulfur contents on the sample BSF larvae and catfish. We used the fermentation of lime fleshing waste with bran and water variables, which are well water, catfish pond water, and rice washing water, for three days. Then, hatching BSF larvae eggs for six days, BSF larvae cultivation for nine days, and application of the BSF larvae on catfish for 12 days. Data were analyzed by one-way ANOVA, then continued using the Duncan Multiple Range Test (DMRT). The result of fermented lime fleshing waste was used on the BSF larvae, and the cultivation contents were analyzed for protein, calcium, and sulfur. The analysis result of the three variables has an average value of protein at around 6.06%, calcium at 0.041%, and sulfur at around 0.016%. The study concludes that BSF larvae, when combined with commercial feed and suitable formulation, could be an effective and efficient alternative feed for catfish while addressing the lime fleshing waste problem.
