Judul: Welfare Management of Asian Giant Tortoise (Manouria emys) and Its Utilization as Display Animals at TMII
Abstrak: Pembebasan lahan di kawasan hutan Kalimantan yang berlebihan mengakibatkan dampak buruk bagi keberlangsungan hidup kura-kura kaki gajah. Salah satu upaya untuk pelestarian kura-kura kaki gajah dilakukan melalui upaya pelestariannnya di luar habitat alaminya (eksitu) seperti yang dilakukan di Taman Reptil Taman Mini Indonesia Indah (TMII). Penelitian ini bertujuan untuk mengidentifikasi pengelolaan dan menilai kesejahteraan kura-kura kaki gajah di Taman Reptil TMII, menganalisis persepsi pengunjung terkait pemanfaatan kura kura kaki gajah sebagai satwa peraga, dan merumuskan rekomendasi pengembangan pemanfaatan kura-kura kaki gajah sebagai satwa peraga. Metode yang digunakan yaitu observasi lapang, wawancara, dan studi literatur. Hasil penelitian menunjukan pengelolaan kura-kura kaki gajah di Taman Reptil TMII termasuk baik dan nilai kesejahteraan satwa termasuk dalam kategori sangat baik dengan nilai rata-rata 80.68. Persepsi pengunjung mengenai pemanfaatan kura-kura kaki gajah sebagai satwa peraga adalah setuju. Rekomendasi pengembangan pemanfaatan kura-kura kaki gajah sebagai satwa peraga yaitu atraksi antara pengunjung dengan satwa melalui kegiatan foto bersama dan memberi pakan dengan didampingi keeper., Excessive land acquisition in Kalimantan Forest areas harms the survival of the asian giant tortoise. One of the efforts to preserve the asian giant tortoise is through conservation efforts outside its natural habitat (ex-situ) finished at the Taman Mini Indonesia Indah (TMII) Reptile Park. This study aims to identify the management and assess the welfare of the asian giant tortoise in the TMII Reptile Park, analyze visitor perceptions regarding the use of the asian giant tortoise as a display animal, and formulate recommendations for the development of the use of the asian giant tortoise as a display animal. The methods used are field observations, interviews, and literature studies. The results showed that the management of the asian giant tortoise in the TMII Reptile Park was good cum the value of animal welfare was in the marvelous category with an average value of 80.68. The visitor's perception regarding the use of the asian giant tortoise as a display animal agrees. Recommendations for the development utilization of asian giant tortoise as display animals are attractions between visitors and animals through group photos and feeding activities accompanied by a keeper.

Data didapatkan dari observasi lapang, studi literatur, wawancara dengan animal keeper dan pengunjung. Penilaian implementasi kesejahteraan Gajah Sumatra dalam kategori sangat baik dengan nilai rata-rata 89,96. Bentuk pemanfaatan Gajah Sumatra di TRM Serulingmas meliputi kegiatan pemberian pakan, berfoto, menyentuh gajah dan display gajah. Secara keseluruhan pengunjung memiliki persepsi yang baik, dengan nilai rata-rata TCR 82,94% untuk pengelolaan kesejahteraan Gajah Sumatra dan TCR untuk pemanfaatan gajah sebagai objek wisata sebesar 79,22%. Mayoritas pengunjung tertarik dengan keberadaan Gajah Sumatra di TRM Serulingmas. Strategi pengembangan pemanfaatan Gajah Sumatra dapat dilakukan dengan penetapan harga biaya tambahan, pengembangan program wisata dan peningkatan sarana dan prasarana wisata., Sumatran elephants are critically endangered. This condition calls for the role of exsitu conservation institutions, one of which is Taman Rekreasi Margasatwa Serulingmas. The study aimed to analyze the management and welfare level of sumatran elephants, identify the form of utilization of sumatran elephants, analyze visitor perceptions and preferences for the use of sumatran elephants, and formulate a development strategy for the use of sumatran elephants.

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.
