Judul: Identifikasi Batas Lapang Tana „Ulen Lalut Birai dan Inventarisasi Aturan Pengelolaannya di Taman Nasional Kayan Mentarang
Abstrak: Kayan Mentarang National Park has an area 1.3 million Ha (Wulffraat et al. 2005). The park is the largest conservation area in Kalimantan. The area situated in eleven regions of traditional community. The society has a strong interaction with the region, that rose concept of Tana „Ulen. Tana „Ulen have a function as a mechanism of resources management. The society said the Tana „Ulen is located within the River Enggeng. Mapping and identification boundary of actual Tana „Ulen is urgently needed. Inventory regarding management have been carried out by the region managers such as BPTU and BTNKM. The activities aims to collect kinds management of Tana „Ulen Lalut Birai. The information is expected to help the managers of the region such as BTNKM, BPTU and others. This research was held in October to December 2011 in Kayan Mentarang National Park. Boundary of Tana „Ulen Lalut Birai was done based on discussion and ground checking methods. Boundary line of Tana „Ulen was done with connecting the coordinates and discussion with the community. Rules of management was collected by discussions, interviews and another references documents in the community and BTNKM. The information was analyzed using conservation area management rules that apply at this time. Boundary of Tana „Ulen Lalut Birai was a mountains, hills, mountain ridge, ridge, valley and gorge. Tana „Ulen area located on the River Enggeng and part of the Sub Watershed Kayan River. The area was located within three zoning of Kayan Mentarang National Park, namely; special zone (zona khusus), forest utilization zone (zona pemanfaatan) and the jungle zone (zona rimba). The area cover of about 11.037 Ha and it‟s perimeter was about 56 km. The society decided to limit the area using the last spring that flows into the River Enggeng. The rules of management Tana „Ulen in the society such as document custom rules, village rules and the rules that have not been written. Management of applied by Kayan Mentarang National Park was contained in the Work Plan Budget Ministry Institutions 2012. The management conducted by BPTU and BTNKM has supported conservation areas, but needs to be adjusted again between the management system and zoning of the area.

Judul: Analisis Efektivitas Pengelolaan Stasiun Penelitian Hutan Tropis Lalut Birai di Taman Nasional Kayan Mentarang.
Abstrak: Stasiun Penelitian Hutan Tropis Lalut Birai (SPHTLB) terdapat di Kawasan Taman Nasional Kayan Mentarang (TNKM), Kabupaten Malinau, Kalimantan Utara, berfungsi sebagai tempat penelitian terpadu dengan objek penelitian berupa ekosistem dan keanekaragaman hayati hutan tropis di Tana ‘Ulen (Hutan adat suku Dayak Kenyah) masyarakat desa Long Alango. Sejak tahun 2011, pengelolaan SPHTLB diserahkan kepada Badan Pengelola Tana ‘Ulen (BPTU) sebagai implementasi pengelolaan kolaboratif TNKM. Tujuan penelitian ini adalah menganalisis efektivitas pengelolaan SPHTLB oleh BPTU berdasarkan empat (4) kriteria, yaitu: (1) kapasitas pengelolaan, (2) sarana dan prasarana, (3) penggunaan oleh peneliti, dan (4) daya tarik penelitian. Pengumpulan data lapang dilakukan melalui wawancara mendalam, observasi lapangan, dan pelacakan dokumen. Hasil penilaian menunjukkan kapasitas pengelolaan, sarana dan prasarana dinilai lemah, sedangkan penggunaan oleh peneliti dan daya tarik penelitian dinilai rendah, sehingga dapat disimpulkan bahwa pengelolaan SPHTLB masih jauh dari efektif. Diperlukan dukungan konsorsium para pihak untuk menyusun Rencana Induk Penelitian (Research Master Plan), menguatkan basis legal dan tata kelola BPTU, serta melakukan promosi spesifik tentang pendidikan dan penelitian untuk meningkatkan efektivitas pengelolaan SPHLTB.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
