Judul: Studi keanekaragaman hayati dan sosial budaya masyarakat agraris di desa Pulau Muda, Kuala Kampar, Propinsi Riau
Abstrak: Kepentingan ekonomi dan pemenuhan kebutuhan hidup yang terus berkembang mendorong usaha pertanian yang akan terus meningkat. Sementara itu, deforestasi dan degradasi lahan mangrove untuk aktivitas lain seperti pertanian akan mengaki- batkan dampak negatif terhadap ekosistem baik karakteristik fisika-kimia, biologi maupun keseimbangan ekologis (Aksornkoae, 1993). Pembangunan kehutanan sebagai bagian dari pembangunan nasional yang berkelanjutan mutlak untuk mampu menjembatani kepentingan ekonomi dan ekologi tersebut karena juga menentukan keberlanjutan sosial budaya masyarakat. Desa Pulau Muda terletak di daerah peralihan antara air tawar dan air asin muara Sungai Kampar yang berimplikasi pada keanekaragaman ekosistemnya. Desa ini memiliki jarak ± 35 km dari mulut muara dan secara berkala dipengaruhi oleh pertemuan arus bono. Dengan luas 898 km², desa ini memiliki tipe eko- sistem hutan rawa gambut di dua daratan Sumatera yang dipisahkan oleh Sungai Kampar dan ekosistem mangrove peralihan di 4 pulau endapan yang tersebar di perairan muara, yaitu Pulau Muda, Pulau Ketam, Pulau Baru dan Pulau Timur. Usaha pertanian sawah diintroduksikan oleh masyarakat agraris setempat pada bagian dalam Pulau Muda, sementara bagian tepian pulau ditempati oleh komunitas vegetasi mangrove. Penelitian keanekaragaman flora mengambil komunitas mangrove di tepian Pulau Muda sebagai obyek mengingat letaknya yang berbatasan dengan lahan pertanian di bagian dalam Pulau Muda sehingga dapat dipelajari pengaruh umur endapan dan aktivitas masyarakat setempat terhadap komunitas vegetasi mangrove pulau. ...

Judul: Pengelolaan Kolaboratif Ekosistem Hutan Gambut Semenanjung Kampar, Provinsi RiauSupriatin
Abstrak: Various utilization to the natural resources at Kampar Peninsula has indicated resources degradation that could threaten its’ status. The aims of this research were to indentify natural resources’ characteristic, usage, and related issues; to analyze stakeholders’ of Kampar Peninsula management, its’ social capital, and related issues; to analyze policy and institutional arrangement; to analyze determinant variables of Kampar Peninsula management; and to formulate institution of Kampar Peninsula collaborative management. The study was conducted from February to May 2010 at Kampar Peninsula, using qualitative method. The data was collected through a collection of documents, field observation, in-depth interviews, focus groups discussion, and participate in meetings were related to the research topic. Data were analyzed qualitatively using stakeholders analysis, social capital analysis, and content analysis (policy analysis). The result showed that resources potency of Kampar Peninsula have degraded gradually by uncontrolled water management. More than 70 stakeholders were identified while regulation and policy that directly regulate peatland management least possible. The objective of Kampar Peninsula collaborative management is to realize sustainability Kampar Peninsula peat swamp forest ecosystem management on the landscape scale. Kampar Peninsula collaborative management can be realized through zoning that includes 5 main zones. Collaborative institution act as a "co-manager" for KPHP Tasik Besar Serkap and play the role as a "center of excellence". Meanwhile strengthening and institutionalization of social capital, mastering the technology of water management, strengthening the financial ability of the main actors, and the readiness of human resources are a precondition for realizing collaborative management.

Judul: Pengaruh Pairing pada Isotop Sn dengan Menggunakan Pemodelan Sembilan Tingkat Energi
Abstrak: Formation of the neutron-rich tin isotopes (Sn isotopes) is the one of the interesting topics in the field of nuclear reaction, especially regarding the stability of the heavy nuclei. Calculations of total energy using the BCS approach using five energy levels can only calculate the total energy up to Sn50132. On the other hand, the experiment continues and has exceeded the formation of isotopes. Therefore, there is need for a new model to accomadate more neutrons. In this research, Sn isotopes is modelled using nine energy levels and constant interaction potential to explain the pairing phenomenon up to Sn50154. However, to obtain more accurate results, other methods to minimize the differences with the experimental results are clearly needed here.
