Abstract

Mulberry (Morus sp.) is the primary feed for silkworms (Bombyx mori L.) and determines cocoon quality. However, limited land availability and seasonal changes pose challenges for a consistent mulberry leaf supply, prompting research into alternative feeds. This study aimed to evaluate the effects of alternative feeds on the growth of B. mori, including the length and width of silkworms, the number of live and dead silkworms, and the feed consumption of silkworms. A total of 500 silkworms were divided into six treatments with three replicates each. The treatments were mulberry leaves (K), castor leaves (P1), cassava leaves (P2), broiler chicken feed (P3), castor and mulberry leaves combination (P4), cassava and mulberry leaves combination (P5), broiler chicken feed and mulberry leaves combination (P6). Combined feeds were given at a 1:1 ratio. The results confirmed that B. mori exclusively feeds on mulberry leaves, as no silkworms survived  on P1, P2, or P3 treatments. All combination feed treatments (P4, P5, P6) showed that silkworm growth results were not significantly different from the control treatment (K). Therefore, we recommend using all combination feeds as an alternative feed in B. mori cultivation. However, the best combination feed treatment was shown by P6 with the highest silkworm length and width (3.69 cm; 0.57 cm) and the highest feed consumption (44.16 grams), and P5 with the highest percentage of survival rate (75%) and the lowest percentage of death rate (25%).

Abstract

This study elucidates the diversity of birds at the campus of Universitas Sulawesi Barat, a region that is part of the Wallacea ecosystem, which is renowned for its high biodiversity. The research involved an inventory of 22 bird species belonging to 17 families, with a total of 180 individuals recorded. Among the observed species, seven were distributed across various habitat types, while 13 others were found in habitats less influenced by human activities, such as grasslands, shrubs, and trees. Interestingly, two species, Perkutut Jawa and Kacamata Sulawesi, were exclusively found in habitats frequently affected by human activities, such as settlements and plantations. The study also revealed that approximately 27.27% of the 22 recorded bird species are Sulawesi endemic species, while 72.73% are non-endemic species. These findings provide important insights into the composition and distribution of birds in the study area and have significant implications for conservation efforts. Protecting natural habitats, especially those supporting endemic species, should be a priority. In addition, a better understanding of how birds interact with human-modified habitats is necessary to develop effective conservation strategies. Further studies on specific species may also be required in environments that are increasingly fragmented by human activities. Advancing knowledge in ornithology is essential for preserving bird diversity in the Wallacea region.
