Abstrak: Penelitian ini bertujuan untuk melihat proses pembentukan kelompok Tani Pelestari Hutan di Taman Hutan Raya Nipa—Nipa (Tahura Nipa-Nipa) dan tingkat partisipasi anggota KPTH tahura Nipa-Nipa dalam pengelolaan Hutan.. Penelitian dini dilakukan di Tahura Nipa-Nipa pada kelurahan Watu- watu dan Tipulu dengan sampel sebanyak 70 KK. Variabel yang diamati adalah proses pembentukan KPTH berupa latar belakang dan tujuan pembentukan KPTH, serta tingkat partisipasi kelompok dalam pengelolaan Hutan di Tahura Nipa-Nipa. Data hasil penelitian ditabulasi dan diberi skoring berdasarkan skala Likert. Hasil penelitian adalah KPTH dibentuk pada awalnya karena adanya keinginan masyarakat untuk mengelola kawasan Tahura dengan lestari sekaligus dapat mensejahterakan anggotanya. Tingkat partispasi masyarakat pada tahap perencanaan pembentukan kelompok tergolong rendah, sedangkan tingkat partispasi anggota KPTH pada pengorganisasian dan pelaksanaan program tergolong tingkat partisipasi tinggi, hal ini disebabkan karena adanya kemauan masyarakat untuk mnegelola hutan secara lestari.

This study used a simple random sampling method. The observed variables were the process of forming a KPTH in the form of the background and purpose of establishing a KPTH, as well as the level of group participation in forest management in Tahura Nipa-Nipa. The research data were tabulated and scored based on a Likert scale. The results of research on the background of the KPTH were formed is the desire of the community to manage the Tahura area sustainably while at the same time be able to prosper its members. The level of community participation at the planning stage of group formation is relatively low, while the level of participation of KPTH members in organizing and implementing programs is classified as a high level of participation, this is due to the willingness of the community to manage forests sustainably.

Supercritical carbon dioxide method has starting to be used as environmental friendly method in preserving wood. It is expected to maintain physical and mechanical properties of bamboo. The purpose of this study was to determine the effect of the duration times of supercritical conditions and permethrin preservative concentrations on optimization of shear strength of laminated bamboo impregnated by using supercritical carbon dioxide in the initial process (blades) and final process (laminated bamboo). The RSM-CCD experimental design was used to determine the effect of duration times of supercritical carbon dioxide for 20, 25, 30, 35, 40 minutes and the effect of permethrin concentrations 0.1, 0.3, and 0.5% against the shear strength of laminated bamboos. Response surface analysis, using 10 version of design expert software, has been done to get the optimum condition which would produce maximum of shear strength. The results showed that permethrin concentrations have stronger influenced (based on RSM analysis) on the shear strength and durability of laminated bamboo than the times of supercritical carbon dioxide conditions. Optimization of the two combinations of increasing shear strength and endurance were supercritical conditions = 22.71 minutes, and preservative permethrin concentration = 0.24%. Shear strength of shear strength and decrease in combination weight is 85 kg / cm2 and 0.38%.
Abstrak: Penelitian ini bertujuan (1) Untuk mengetahui jenis dan keanekaragaman bambu yang terdapat di Kelurahan Tobimeita Kecamatan Nambo Kota Kendari (2) Untuk mengetahui bentuk pemanfaatan bambu oleh masyarakat di Kelurahan Tobimeita Kecamatan Nambo Kota Kendari. Penelitian ini dilakukan di Kelurahan Tobimeita Kecamatan Nambo Kota Kendari pada Bulan Juli-November 2018 menggunakan metode observasi lapangan dengan anilisis vegetasi untuk mengetahui jenis dan keanekaragaman bambu dan wawancara untuk mengetahui pemanfaatan bambu oleh masyarakat. Hasil penelitian menujukan bahwa, terdapat 5 jenis bambu yaitu bambu wuluh (Schizotachyum blumei) berjumlah 288 rumpun dengan keanekaragaman 0,262, bambu kuning (Bambusa vulgaris var. Striata ex Wendl) terdapat 3 rumpun dengan keanekaragaman 0,042, bambu ampel (Bambusa vulgaris Scharder ex Wendland) berjumlah 22 rumpun dengan keanekaragaman 0,179, bambu wulung (Gigantochloa atroviolacea) terdapat 56 rumpun keanekaragaman 0,299 dan bambu betung (Dendrocalamus asper) terdapat 26 rumpun dengan keanekaragaman yaitu 0,198. Jenis bambu yang dimanfaatkan oleh masyarakat Kelurahan Tobimeita yaitu bambu betung yang digunakan untuk pagar, kandang ayam, lantai rumah atau lantai gazebo dan bambu wuluh yang digunakan untuk tiang tempat menjalar sayuran kacang panjang, peyangga atap tradisional seperti atap rumbia dan dinding anyaman bambu. Kata Kunci: Bambu, jenis Bambu, Keanekaragaman dan Pemanfaatan Types, Diversity and Use of Bamboo by Tobimeita Village, Nambo Sub-District, Kendari CityAbstract: This study aims (1) to determine the type and diversity of bamboo found in Tobimeita Village, Nambo Sub-District, Kendari City (2) to find out the form of bamboo use by the community in Tobimeita Sub-District, Nambo Sub-District, Kendari City. This research was conducted in Tobimeita Sub-District, Nambo Subdistrict, Kendari City in July-November 2018 using a field observation method with vegetation analysis to determine the type and diversity of bamboo and interviews to find out the use of bamboo by the community. The results showed that there were 5 types of bamboo, namely wuluh bamboo (Schizotachyum blumei) with 288 clumps with diversity 0,262, yellow bamboo (Bambusa vulgaris var. Striata ex Wendl) there were 3 clumps with a diversity of 0,042, bamboo ampel (Bambusa vulgaris Scharder ex Wendland) there were 22 clumps with diversity of 0.179, wulung bamboo (Gigantochloa atroviolacea) there were 56 clumps of diversity 0,299 and betung bamboo (Dendrocalamus asper) there were 26 clumps with diversity which was 0,198. The type of bamboo used by the community of Tobimeita Village is betung bamboo which is used for fencing, chicken coop, house floor or gazebo floor and wuluh bamboo which is used for pillars spreading long bean vegetables, traditional roof supports such as thatched roofs and woven bamboo walls.

This study was conducted to determine the presence of the insecticide permethrin and its retention gradients within the structure of laminated bamboo after treatment using supercritical carbon dioxide (SC-CO2) as the carrier solvent. the presence of permetrin was based on functional group differences indicated by FT-IR analyses before and after the preservative treatment. Permethrin retentions in the treated bamboo materials ranged from 0.0020 to 0.0022%. This result indicated that the preservative treatment of laminated bamboo using SC-CO2 as a carrier solvent produced evenly distributed chemical an effective level. There was no signicant distribution gradient of the preservative observed over the layers of the treated laminated bamboo arranged with outer-inner surface laminations. The current treatment condition is potential to produce laminated bamboo products completely resistant to biodegradation.
Abstrak: This study aims to determine the distribution and characteristics of stingless bee nests (Trigona sp) found in the Haluoleo University Campus Forest Area. The outer nest's characteristics are the shape of the entrance to the nest, the nest's distance from the water source, and the nest's height from the ground. The nests' internal characteristics were observed, namely the pollen and honey pots' shape and the pollen and honey pots size. The results showed that around the Haluoleo University campus forest, 11 nests of Trigona sp were located in an open area with high light intensity and not humid. There are two forms of nest entrance, namely oval and circular shapes. The honey and pollen pots are ovoid with an average diameter of 1.01 cm, the average nest distance from the water source is 186.4 m, and the average nest distance from the ground is 3.4 m. Key words: stingless bee, nest characteristic, Halu Oleo University forest, nest distribution
