Judul: Study of Hunting and Utilization of Asiatic Softshell Turtle (Amyda cartilaginea) by Anak Dalam Tribe in Bukit Duabelas National Park
Abstrak: Labi-labi (Amyda cartilaginea) merupakan salah satu jenis reptil yang tergolong ke dalam famili Tryonichidae yang dimanfaatkan oleh Suku Anak Dalam (SAD) di Taman Nasional Bukit Duabelas. Studi terkait pemanfaatan labi-labi oleh SAD telah dilakukan, namun belum dijelaskan secara rinci mengenai teknik dalam perburuan satwa terkhusus labi-labi. Oleh karena itu, dibutuhkan kajian tentang teknik perburuan serta bentuk pemanfaatan labi-labi oleh SAD di Taman Nasional Bukit Duabelas. Metode yang digunakan yaitu observasi partisipatif, studi pustaka, dan wawancara kepada 40 orang responden. Hasil penelitian menunjukkan bahwa masyarakat SAD berburu labi-labi di siang hari (63%) dengan teknik tradisional menggunakan tero (69%). Perburuan dilakukan satu kali seminggu (42%) dan sebanyak 55% dari total responden selalu berhasil mendapatkan labi-labi. Dalam satu kali berburu biasanya masyarakat mendapatkan 2 ekor labi-labi (50%). Daging labi-labi dimanfaatkan sebagai konsumsi (63%) dan paling banyak diolah dengan cara direbus (60%). Hasil analisis uji chi-square menunjukkan adanya hubungan yang signifikan antara jenis kelamin responden dengan alat (0,044) dan waktu perburuan. Terdapat juga hubungan yang signifikan antara tingkat pendidikan dengan bentuk (0,000), bagian (0,023), dan cara pemanfaatan (0,000)., Asiatic Softshell Turtle (Amyda cartilaginea) is a type of reptile belongs to the Tryonichidae family which is utilized by the Anak Dalam Tribe (SAD) in Bukit Duabelas National Park. Studies related to the use of turtles by SAD have been carried out, but the techniques for hunting animals, especially turtles, have not been explained in detail. Therefore, a study is needed on hunting techniques and forms of use of turtles by SAD in Bukit Duabelas National Park. The method used is participatory observation, literature study, and interviews with 40 respondents. The results showed that the SAD people hunted turtles during the day (63%) with traditional techniques using tero (69%). The hunt was carried out once a week (42%) and as many as 55% of the total respondents always managed to catch a turtle. In one hunt, people usually get 2 turtles (50%). Turtle meat is used for consumption (63%) and most of it is processed by boiling (60%). The results of the chi-square test analysis showed a significant relationship between the sex of the respondents and tools (0,044) and hunting time (0,012). There is also a significant relationship between education level and form (0,000), portion (0,023), and method of utilization (0,000).

Judul: Study of Hunting and Utilization of Water Monitor (Varanus salvator) by Anak Dalam Tribe in Bukit Duabelas National Park
Abstrak: Biawak air merupakan reptil famili Varanidae yang dimanfaatkan oleh Suku Anak Dalam. Data terkait perburuan dan pemanfaatan tersebut saat ini masih terbatas. Penelitian ini bertujuan mengidentifikasi teknik perburuan serta bentuk dan jenis pemanfaatan biawak air oleh Suku Anak Dalam. Metode yang digunakan adalah observasi partisipatif, wawancara, dan studi pustaka. Jumlah responden yang diwawancarai yaitu sebanyak 40 responden. Perburuan biawak air dilakukan dengan teknik tradisional menggunakan alat jerat (32,5%) pada siang hari (60%). Perburuan biawak air didominasi selalu berhasil (65%) dengan intensitas 1x/minggu (40%) dan keberhasilan 2 ekor (57,5%). Biawak air dimanfaatkan untuk kebutuhan konsumsi (67,5%) pada bagian daging (67,5%) dengan cara direbus, digoreng, dibakar, serta disalai. Terdapat hubungan signifikan antara pendidikan dan pekerjaan dengan alat perburuan, jenis kelamin dan pendapatan dengan intensitas perburuan, pendidikan dan pekerjaan dengan bentuk pemanfaatan, pendidikan dan pekerjaan dengan bagian yang dimanfaatkan, serta antara pendidikan dengan cara pemanfaatan., Water monitor is a reptile of the Varanidae family that is utilized by the Anak Dalam Tribe. Data related to hunting and utilization are currently limited. This study aims to identify hunting technique also forms and type of water monitor utilization by the Anak Dalam Tribe. The methods used are participatory observation, interviews, and literature study. The number of respondents interviewed was 40 respondents. Water monitor hunting is carried out with traditional techniques using snares (32,5%) during the day (60%). Water monitor hunting was predominantly successful (65%) with an intensity of 1x/week (40%) and a success rate of 2 tails (57,5%). Water monitor lizards are utilized for consumption (67,5%) on the meat part (67,5%) by boiling, frying, grilling, and salting. There is a significant relationship between education and occupation with hunting tools, gender and income with hunting intensity, education and occupation with form of utilization, education and occupation with parts of utilization, also between education with method of utilization.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
