Abstract

Anggrek alam merupakan salah satu hasil hutan non kayu yang termasuk dalam golongan tanaman hias yang sangat digemari. Tingginya permintaan anggrek menyebabkan anggrek memiliki nilai jual yang sangat tinggi. Hal ini menjadi salah satu penyebab tingginya eksploitasi anggrek alam dalam hutan. kegiatan eksploitasi secara terus menerus menjadikan anggrek alam terancam punah. Tujuan pengabdian ini adalah untuk melestarikan tanaman anggrek khususnya anggrek alam yang terancam punah melalui kegiatan budidaya anggrek alam secara vegetatif melalui pemisahan rumpun dan stek. Metode yang digunakan dalam program ini adalah metode penyuluhan dan pelatihan tentang perbanyakan anggrek alam secara vegetative melalui stek dan pemisahan rumpun. Hasil yang diperoleh dalam kegiatan ini yaitu indukan anggrek alam yang tergolong sympodial (Cymbidium sp., Bulbophyllum sp. Grammatophyllum sp.) diperbanyak melalui pemisahan rumpun. Satu indukan dapat dipisahkan menjadi 4-5 rumpun. Sedangkan untuk anggrek alam yang tergolong monopodial (Dendrobium sp. dan Vanda sp.) diperbanyak dengan cara stek karena model pertumbuhannya secara vertikal. Satu indukan dewasa juga dapat menghasilkan 4 – 5 stek. Pola kerja sama yang dijalankan dalam kegiatan ini yaitu melalui kerja sama dengan kelompok-kelompok tani anggrek alam yang ada di Desa Karunia Kecamatan Palolo Kabupaten Sigi sebagai penyedia indukan anggrek yang selanjutnya diperbanyak secara vegetative melalui stek dan pemisahan rumpun

Abstract

Indonesia is a country with a tropical climate. Rainfall in Indonesia is quite high and greatly affects the growth of mushrooms (fungi). The use of wood cannot be separated from the manufacture of traditional houses. These traditional houses made of wood are very susceptible to fungal attacks. Wood or wood rot fungi are fungi that live attached to decaying trees, but some types of wood fungi grow on living tree trunks and on dead trees. Wood rot fungi are heterotrophic, or do not produce their own food, This study aims to determine the resistance of white teak wood (Gmelina arborea Roxb) against wood-decay fungi. The research method used was a completely randomized factorial design consisting of two factors: factor I (wood) and factor II (fungi). The test samples used for the combination of the two factors measured 5x 2.50x1.50 cm, with a total of 9 test samples placed in culture jars separately. All samples from the base, middle, and tip tests were placed into a jar containing PSA media, and the inoculated mushroom culture was added to the jar. The observed parameters used an analysis of variance to determine whether the treatment had a significant effect on the decrease in teak wood weight. The Least Significant Difference (LSD) test was carried out to determine whether there were significant differences between treatments or not.

Abstract

The basic properties of this wood are also greatly influenced by factors within the wood and external factors such as where the wood grows. This research was conducted from June to September 2024 at the Soil Science Laboratory, Faculty of Agriculture, and the Mechanical Engineering Laboratory, Faculty of Engineering, Tadulako University to determine the physical and mechanical properties of white teak wood from Ampana, Poso, Central Sulawesi. The design method used in this study is RAL Factorial with two factors, namely: Factor A variation of the axial direction (base, middle, tip) and, Factor B variation of the radial direction (near the heart, middle, near the skin), so that there are 9 treatments and each treatment is repeated 5 times. The results of the study showed that both physical and mechanical properties were influenced by the position of the wood in the trunk where the position of the wood in the trunk affects the physical and mechanical properties of the wood studied. Based on the MOE value, the white teak wood studied is included in the strength class V. Based on the MOR value and compressive strength parallel to the grain, the wood studied is included in the strength class III which can be used as raw material for furniture and light construction.
