Judul: Resilience of Tourism Destination Management in Ex-Situ Conservation Institutions during the Covid-19 Pandemic
Abstrak: Taman Margasatwa Ragunan (TMR) merupakan salah satu destinasi wisata lembaga konservasi ex-situ yang terletak di Pasar Minggu, Jakarta Selatan. Munculnya pandemi Covid-19 memengaruhi resiliensi pengelola dan masyarakat selaku pelaku wisata. Penurunan jumlah pengunjung akan berdampak langsung pada penurunan pendapatan retribusi objek wisata dan pendapatan masyarakat. Penelitian ini bertujuan menganalisis strategi resiliensi yang dilakukan oleh pelaku wisata akibat pandemi Covid 19. Metode pengumpulan data berupa wawancara, studi pustaka, dan observasi lapang. Pemilihan responden menggunakan teknik purposive accidental sampling. Penelitian ini menggunakan analisis data kuantitatif dan deskrisptif kualitatif. Hasil penelitian menunjukkan bahwa perspesi pengelola cukup baik sedangkan untuk pelaku wisata sangat baik. Hal ini dikarenakan pelaku wisata sangat merasakan dampak dari akibat penutupan TMR yang berpengaruh terhadap pendapatan utama. Strategi mitigasi yang dilakukan adalah melakukan pola pergiliran bagi pelaku pendukung wisata. Adapun strategi adaptasi yang dilakukan oleh pengelola dan pelaku wisata yaitu melalui pengetahuan dan pengalaman yang dimiliki, pembelajaran inovatif yang dilakukan, dan akses informasi. Tingkat persepsi yang baik menyebabkan pengelola dan pelaku wisata dapat memahami upaya mitigasi terhadap resiko selama masa pandemi Covid-19., Ragunan Wildlife Park or Zoo (TMR) is one of the tourism destinations for ex-situ conservation institutions located in Pasar Minggu, South Jakarta. The emergence of the Covid-19 pandemi affects the resilience of managers and the community as tourism actors. The decrease in the number of visitors have directly affected on the decline in retribution revenue for tourist objects. The research aimed at the analysis of resilience strategy conducted by all parties during pandemic Covid 19. Data collection methods in the form of interviews, literature study, and field observations. The selection of respondents using purposive accidental sampling technique. This study used quantitative and descriptive qualitative data analysis. The results showed that the manager's perception was quite good, while for tourism actors it was very good. This is because tourism actors really feel the impact of the closure of the TMR which affects the main income. The mitigation strategy carried out is to conduct a rotation pattern for tourism supporting actors. While adaptations made by tourism managers and actors are through their knowledge and experience, innovative learning that is carried out, and connectivity. A good level of perception causes tourism managers and actors to understand mitigation efforts against risks during the Covid-19 pandemi.

Judul: The Economic Impact of the Covid-19 Pandemic on the  Kinantan Wildlife and Cultural Park Bukittinggi and its Recovery Strategy
Abstrak: Taman Margasatwa dan Budaya Kinantan (TMSBK) merupakan salah satu objek wisata unggulan di Kota Bukittinggi yang aktivitas ekonominya terdampak akibat pandemi Covid-19. Penelitian ini bertujuan untuk menganalisis perubahan jumlah kunjungan wisatawan pada setiap periode pembatasan mobilitas akibat pandemi Covid-19 di TMSBK, memperkirakan nilai kerugian finansial akibat pandemi Covid-19 terhadap pelaku usaha di sekitar objek wisata TMSBK, dan menganalisis strategi pemulihan ekonomi pasca pandemi Covid-19 terhadap pelaku usaha di sekitar objek wisata TMSBK. Penelitian ini menggunakan data primer dan data sekunder dengan mengkombinasikan tiga metode yaitu content analysis, analisis pendapatan, dan analisis Strength, Weakness, Opportunities, Threats (SWOT). Hasil penelitian menunjukkan bahwa perubahan jumlah kunjungan setiap periode pembatasan mobilitas di TMSBK mengalami penurunan sebesar 47% dari satu tahun sebelum dan saat adanya pandemi Covid-19. Kerugian finansial objek wisata TMSBK sebesar 55% per tahun, sedangkan hotel 59% per tahun. Strategi utama yaitu memperluas promosi melalui sosial media, rebranding, dan renovasi., Kinantan Wildlife and Cultural Park (TMSBK) is one of the prime tourist destinations in Bukittinggi city whose economic activity has been affected by the Covid-19 pandemic. This study aims to analyze the changes in the number of TMSBK tourists’ visits in each period of mobility restrictions due to the Covid-19 pandemic, to estimate the value of financial losses caused by the Covid-19 pandemic to business located around TMSBK, and to analyze the economic recovery strategies after the Covid-19 pandemic for business located around TMSBK. This study used primary data and secondary data by combining three methods, namely content analysis, income analysis, and Strenghts, Weaknesses, Opportunities, Threats (SWOT) analysis. The results show that changes in the number of visits for each period of mobility restrictions in TMSBK decreased by 47% from one year before and during the Covid-19 pandemic. The financial loss of TMSBK is 55% per year, while hotels are 59% per year. The main recovery strategies are expanding promotions through social media, rebranding, and renovation.

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.
