2025-01-11T06:39:33+00:00

Abstract: Sulawesi's endemic bee Apis dorsata Binghamii is a honey producer that needs to be preserved. The research was carried out in Tawanga Village, Uluiwoi District, East Kolaka Regency from June to November 2024. The aim of the research was to determine the types of food trees and nest trees, whether or not the presence of food plants influences the presence of bee hives, and determine the type of habitat preferred (habitat preference). The research method uses a survey method. Vegetation analysis is expressed in absolute and relative values as formulated by Soerianegara and Indrawan (1988). The effect of the presence of food trees on the presence of nests using a completely randomized design (CRD). Data were analyzed using variance (Anova). If Fhit>Ftab H0 is rejected, H1 is accepted, followed by the BNT test (smallest real difference test). Analysis of habitat types preferred by forest bees using the NEU method (Neu et al. 1974). The results of the research showed that there were 44 types of food plants that produce nectar and pollen, 16 hives and bee trees. The most dominant flower-producing types at tree level are: durian (Durio ziberthinus), pole level; Cocoa (Theobroma cacao), and Cashew (Anacardium occidentale), sapling stage of Cocoa (Theobroma cacao), Coffee (Coffea sp) and seedling stage of Coffee (Coffea sp), Tombira (Vitex glabra), and Puloli (Quercus celebica). There is a very significant influence of the changing climate flower season and the dry climate flower season on the weight of beehive honey. The highest average honey yield is found in the dry season. The most preferred habitat preferences of Apis dorsata Binghamii bees; diameter 24.2 - 58.9 cm. Nest height preference 04.26-13.64 m. Preference Height above sea level 78 – 221.5 m above sea level. Air temperature preference is 30.7-36.80C, and air humidity preference is between 36.5-63.75%.

PENGARUH INTERAKSI ZAT PENGATUR TUMBUH DAN BERBAGAI KOMPOSISI MEDIA TANAM TERHADAP PERKECAMBAHAN BENIH CENDANA (Santalum album LInn)

2025-01-07T10:48:35+00:00

Sandalwood (Santalum album Linn.) is a wood-producing forest plant in the East Nusa Tenggara province (NTT) which has great economic value and is an endemic type of species. The exploitation of the foam plant (Santalum album Linn) which is not offset by its conservation efforts causes the plant to be at risk of extinction. Candana (Santalum album Linn) is also a tree whose seed germination is relatively slow due to the thickness of its skin which inhibits the entrance of water inhibitively so that the germinating process takes a relatively long time Giving ZPT GA3 is believed to help the growth because it contains plant hormones that are available both endogenously and exogeneously and giving the composition of the growing medium can also help to nourish to accelerate plant production. The method used in this study is Complete Random Design (RAL) 2 factors, namely factor A concentration GA3 and factor B composition of soil, sand, chicken stool, cow stool with 9 combinations of each combination of such treatment was repeated 3 times so that 27 experimental units were obtained. Each experimental unit uses 100 mold seeds so the total seed required for 27 experimental units is as much as 2,700 mold seed. The results of the research showed that the concentration of GA3 80% with a cattle stool growing medium of 2 kg, sand 1 kg and soil 1 kg can increase the percentage of spruce, the rate of germination, the wet weight and dry weight of mushroom seed plants (Santalum album Linn).

Pengambilan sampel pohon menggunakan purpossive sampling agar pengambilan sampel pohon lebih representatif (Audina et al., 2020 dalam Anhar dan Sanjaya 2023). Analisis data menggunakan analisis regresi linear, dimana dapat terlihat bagaimana pengaruh diameter batang tanaman pinus dengan produksi getah pinus. Hasil penelitian menunjukkan bahwa diameter batang tidak mempengaruhi produksi getah pinus, hal ini dikarenakan adanya beberapa faktor eksternal dan faktor internal.

KETAHANAN KAYU BAKALA (Alstonia spectabilis) TERHADAP DEGRADASI MARINE BORERS

2024-11-13T05:33:44+00:00

Alstonia spectabilis (Bakala) is a fast-growing tree species native to Southeast Sulawesi, Indonesia, with potential applications in maritime and coastal construction. Despite its promising economic value, Bakala wood is still limited in its use due to a lack of understanding of its physical properties and resistance to marine borers, which can cause significant damage to wood structures in marine environments. This study aims to evaluate the natural resistance of Bakala wood to marine borer attacks. Wood resistance testing was carried out by immersing wood samples in seawater for three months and assessing the damage caused. The results showed significant color changes and hole formation, with damage intensity varying in various parts of the wood. The tip and middle parts showed severe degradation, with damage intensity of 58.8-61.3%, classified as poor according to SNI 01-7207-2006 standards, while the base of the wood showed moderate damage with an average damage intensity of 50.1%. The identified marine borer species responsible for the damage include Teredo navalis (family Teredinidae), Lichenopora (genus bryozoan), and Martesia striata (family Pholadidae). These findings suggest that while Bakala wood has potential for use in coastal and marine applications, its poor resistance to marine borers means that further research into protective treatments or selective use in marine environments is needed.
