Judul: Pengetahuan masyarakat tentang konservasi sumberdaya hutan: studi kasus pada masyarakat Desa Cipeuteuy, Kecamatan Kabandungan, Kawasan Taman Nasional Gunung Halimun Salak, Sukabumi Jawa Barat
Abstrak: Halimun Salak Mountain National Park in accordance with the Decree of Ministry of Forestry No. 282/Kpts-II/1992 covering area of 40.000 ha. TNGH area was enlarged on 2003 become Halimun Salak Mountain National Park (TNGHS) according to the Decree of Ministry of Forestry No. 175/Kpts-II/2003. The extension of TNGHS area changed the status of production forest become one entity of Halimun Salak Mountain National Park area with total area as 113.357 ha. The focus of this research is community knowledge of conservation that realized in prohibition contained in the community and the influence to the utilization activities of community such as agricultural cultivation, tree felling, firewood collecting, and grass taking. Those community activities are conducted in order to meet the economic needs of community. In the other hand, the area status as a national park restricts the community access in conducting those activities because it’s considered can damage the forest. Therefore, it needs to review more deeply the community knowledge about forest resources conservation. This research was conducted by using case study method. Respondent consist of community leader and community members living in five hamlets of Cipeuteuy village that directly or indirectly involve in managing the National Park. It was conducted in five hamlets on one village. The data from field observation and deep interview with communities was classified and analyzed. The result is shown as narrative text and figure, and explained descriptively. This research result shown that Cipeuteuy communities have rules on interacting with forest including prohibitions. The rules arose as a result of learning process on community and socialization of regulation by National Park thus the regulation was gradually adopted in the rules of Cipeuteuy communities. In addition, Cipeuteuy communities’ still conduct utilization activity in National Park area such as agricultural cultivation, logging, collecting fuel wood and collecting the grass for animals feed. Generally, the communities try to avoid utilization that has been prohibited by National Park according to existing regulation or statue, but because of they do not have substitute, the community still continue the activities while trying to minimize the forest damage.

Judul: Dampak Penetapan Taman Nasional Gunung Halimun Salak: Perubahan Strategi Penghidupan Masyarakat Tepian Kawasan Konservasi (Kasus: Desa Cihamerang, Kecamatan Kabandungan, Kabupaten Sukabumi, Jawa Barat).
Abstrak: Bertambahnya jumlah rumah tangga yang bertempat tinggal di kawasan sekitar hutan diiringi dengan pernyusutan kawasan hutan di Indonesia. Bahkan dari tahun ke tahun luas hutan terus berkurang baik di pulau jawa maupun luar pulau jawa. Salah satu upaya perlindungan yang dilakukan atas penyusutan luas tersebut adalah dilakukannya pembagian status dan fungsi kawasan konservasi oleh pemerintah. Perubahan luasan kawasan konservasi terjadi pada tahun 2003 di Taman Nasional Gunung Halimun Salak (TNGHS). Perubahan tersebut mengubah property right regime hutan menjadi state property sehingga akses masyarakat tepian konservasi seperti masyarakat di Desa Cihamerang dalam memanfaatkan/mengolah hutan menurun. Tujuan penelitian ini adalah untuk menganalisis tingkat akses masyarakat terhadap sumber daya hutan, mekanisme akses, perubahan strategi penghidupan, dan hubungan tingkat akses dengan strategi penghidupan di Taman Nasional. Penelitian ini menggunakan pendekatan penelitian kuantitatif dengan teknik purposive sample yang dikuatkan data kualitatif. Hasil penelitian menunjukkan bahwa terjadi perubahan pada masyarakat dalam merekayasa sumber penghidupan sebagai bentuk respon penetapan TNGHS namun tidak terjadi perubahan signifikan pada usaha penghidupan ganda yang artinya masyarakat masih mengandalkan usaha tani di lahan garapan TNGHS.

Judul: Invers Drazin dari Matriks Toeplitz Singular
Abstrak: Matriks Toeplitz adalah matriks yang setiap unsur pada diagonal utama bernilai sama dan setiap unsur pada subdiagonal yang bersesuaian dengan diagonal utama juga bernilai sama. Matriks singular adalah matriks yang tidak bisa ditentukan inversnya. Akan tetapi, dapat diupayakan untuk ditentukan inversnya menggunakan invers matriks yang diperumum. Invers Drazin merupakan salah satu jenis invers matriks yang diperumum. Pada karya ilmiah ini ditentukan invers Drazin dari matriks Toeplitz singular dengan menggunakan metode Leverrier Faddeev. Kemudian, ditentukan invers Drazin dari matriks Toeplitz singular yang direpresentasikan sebagai penjumlahan segitiga bawah dan segitiga atas matriks Toeplitz berdasar pada teorema Gohberg dan Semencul., Toeplitz matrix is a matrix in with element on the main diagonal has the same value and on the subdiagonal corresponding to the main diagonal also has the same value. Singular matrix is a matrix that has no inverse. However, it can be attempted to determine the inverse using a generalized inverse matrix. Inverse Drazin is a type of generalized matrix inverse. This paper discussed the inverse Drazin for a singular Toeplitz matrix using the Leverrier Faddeev method. Then, the Drazin inverse of the singular Toeplitz matrix which is represented as a sum of products of lower and upper triangular Toeplitz matrix based on Gohberg and Semencul theorem.
