Abstract

Pohon palapi, nantu dan bayur merupakan jenis pohon yang terdapat secara alami di Sulawesi Tengah dan merupakan jenis kayu yang banyak digunakan pada industri mebel di kota Palu. Tujuan khusus dalam penelitian ini adalah mempelajari struktur anatomi dan mutu serat tiga jenis kayu asal Sulawesi Tengah. Hasil penelitian menunjukkan bahwa sifat struktur anatomi dari ketiga jenis kayu yang diteliti memiliki karakteristik yang berbeda. Kayu bayur mudah dibedakan dengan nantu dan palapi karena memiliki banyak kristal rhomboid pada sel parenkim aksialnya. Sedangkan palapi mudah dibedakan dari keduanya dengan adanya pori-pori yang hampir seluruhnya soliter dan termasuk kategori langka serta memiliki parenkim aksial yang sangat masif berupa agregat difus. Berdasarkan kualitas seratnya, kayu nantu termasuk kelas I, sedangkan kayu palapi dan bayur termasuk kelas II. Ketiga jenis kayu ini dapat digunakan dalam pembuatan pulp dan kertas.

Abstract

The community has traditionally utilized the swallow’s nest (Collocalia fuciphaga), an edible bird’s net (EBN), as a component in medicines and cosmetics. Within the cave’s walls lies the environment for the swallow’s nest. The nest’s quality and form are taken into account when determining the nest wallet’s selling price. This study intends to ascertain the possible suppression of the bacteria Staphylococcus sp. and Escherichia sp. activity as well as the antioxidant activity of the swallow’s nest from the nest class formed from wood and concrete construction types. The study was conducted directly on dry, hair- and dirt-free, finely powdered, and dissolved in distilled water swallow nests (Collocalia fuciphaga). Testing for antibacterial activity was conducted. Agar well testing for antibacterial activity was carried out using Mueller Hinton Agar (MHA) and chloramphenicol media as positive controls. Ascorbic acid was used as a positive control while 1,1-diphenyl-2-picrylhydrazyl (DPPH) was tested for its ability to scavenge free radicals. The test findings demonstrated that the swallow (Collocalia fuciphaga) had substantial antioxidant activity against DPPH and that the swallow’s nest (Collocalia fuciphaga) had antibacterial activity against Staphylococcus sp. and Escherichia sp. germs. The swallow’s nest’s (Collocalia fuciphaga) antioxidant and antibacterial properties are specific to different nest classes and building kinds, so they may be utilized as a foundation for thought about raising the selling price of bowls, powders, and crumbles in each form of structure.
