Judul: Dinamika pengetahuan lokal dalam mengelola sumber daya hutan dan lahan rawa pada masyarakat di sekitar areal kebakaran
Abstrak: Meski dalam skala yang berbeda-beda, hampir setiap tahun terjadi kebakaran hutan di Indonesia baik di lahan kering maupun di lahan basah (rawa). Salah satu penyebab kebakaran tersebut adalah manusia, baik kebakaran yang disengaja untuk pembukaan lahan atau karena adanya konflik, maupun kebakaran yang tak disengaja karena kelalaian. Pembukaan lahan dengan cara membakar yang dilakukan oleh masyarakat pribumi sering kali dituding sebagai penyebab utama dari kebakaran hutan. Namun perlu diingat bahwa masyarakat memiliki norma-norma yang mengatur pemanfaatan sumber daya alam yang menjaga kelestariannya. Untuk itu penelitian ini mencoba mengkaji bentuk-bentuk pengelolaan sumber daya hutan dan lahan rawa oleh masyarakat, dinamika pengetahuan lokal masyarakat dari waktu ke waktu dan meninjau kaitan antara pola pengelolaan sumber daya hutan dan lahan rawa dengan kebakaran yang terjadi. Penelitian dilakukan di Desa Talang Batu, Kecamatan Mesuji, Kabupaten Tulang Bawang, Propinsi Lampung, yang terdiri dari empat dusun yaitu: Dusun Talang Batu, Dusun Tebing Tinggi, Dusun Talang Gunung, dan Dusun Stajim. Pendekatan yang dilakukan adalah pengkajian masyarakat secara partisipatif (participatory rural appraisal).

Judul: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
