The results showed that macroscopically the studied wood fossils had brick red, gray, yellow, brown, and black in the first sample (FKA), and the second sample (FKB) had white, gray, and light brown colors, which this color difference was probably due to the cells being mixed with other inorganic elements even though they were found in adjacent locations. Another observation of the macroscopic features of the two samples indicated that cells were still obviously visible as on normal wood, such as pores, rays, and axial intercellular canal. Based on the characteristics of AIC, it was found to have general features that were often found in several types of wood in the Dipterocarpaceae family. The results of measuring the hardness value, the two fossil samples have the same hardness value, namely 4 Mohs scale. For the meantime, the specific gravity of the FKA and FKB samples were 2.54 and 2.35, respectively.

Fossil Wood is wood that has petrified as a result of wood or plant stems being buried by sediment, does not experience decay and the cells in the wood are replaced by minerals over a long period of time but the outer structure of the wood is still maintained. One way to find out the characteristics of fossil wood is by observing or characterizing it both macroscopically and microscopically. This study aims to determine the macroscopic characteristics, hardness values and density of wood fossils found in Loa Tebu Village, Kutai Ketanegara. Observations of macroscopic characteristics included the color of wood fossils which were observed by naked eye and with a loupe magnification of 10x, and observations of other macroscopic characteristics were carried out on three areas of wood namely transverse, tangential and radial planes using a Nikon SMZ 645 Stereo Microscope with a magnification of 30x. The hardness value uses a rock hardness test tool, namely "Diamond Selector II", while the density uses the general calculation standard for specific gravity, namely the ratio of mass to volume. The results showed that the characteristics of the fossil wood from Loa Tebu were light brown, dark brown, white and gray in color. The color found in the wood fossils is probably caused by cells that have been mixed with inorganic elements and mineral constituents around the location of the wood fossils. Another macroscopic structural observation was the discovery of wood cells such as those of broad leaf wood in general, namely the presence of vessel cells (pores), radius cells and clusters of fiber cells. Axial intercellular channels (SIA) were also found in the samples and arranged tangentially. The AIA characteristics found here are common characteristics that are often found in several species of wood from the Dipterocarpaceae family. The results of the measurement of the sample hardness value were 4 on the Mohs scale and the density was 3.26

The community has traditionally utilized the swallowâ€™s nest (Collocalia fuciphaga), an edible birdâ€™s net (EBN), as a component in medicines and cosmetics. Within the caveâ€™s walls lies the environment for the swallowâ€™s nest. The nestâ€™s quality and form are taken into account when determining the nest walletâ€™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 swallowâ€™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 swallowâ€™s nest (Collocalia fuciphaga) had antibacterial activity against Staphylococcus sp. and Escherichia sp. germs. The swallowâ€™s nestâ€™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.

This activity intends to educate residents of Purwajaya Village with information, education, and awareness about the value of finding wood fossils in their area, and also provide input on the uses that can be made by the local residents who live near wood fossil finds. The discovery of the world's longest fossil wood log in Purwajaya Village, as well as in several other villages, attracts precious stone hunters and dealers who wish to dig up these historical natural resources assets to trade. If this trend continues, Borneo's botanical diversity would eventually decline. Most of the people are unaware of the hidden assets found in their village, namely fossil wood, and they are uninformed of the rewards they will receive if these assets are properly handled. The program took place in residential areas close to where the wood fossils were discovered, and it was entirely interactive. The activity stages include the presentation of wood fossils and continued discussions with residents. The results of the activity showed that the community's curiosity is very high, especially the people of Purwajaya Village towards the wood fossils found in their village, their history and its use. The activity went well, especially for the villagers as the participants from the Marga Mulya hamlet farmer group, Purwajaya Village. This can be seen from the discussion and the desire for similar activities to be carried out in the form of the practice of how to utilize fossil wood in the future.
