Judul: Strategy and Livelihood Structure for Farmer Household After Agrotourism Development
Abstrak: Sektor pertanian tidak hanya digunakan untuk memproduksi pangan atau bahan mentah industri tetapi juga dimanfaatkan sebagai sarana wisata dan kegiatan edukasi. Kegiatan wisata yang memanfaatkan lahan pertanian disebut dengan agrowisata. Kehadiran agrowisata ini membawa banyak dampak positif bagi masyarakat di sekitar tempat wisata, seperti peningkatan ekonomi masyarakat sebab adanya penyerapan tenaga kerja untuk bidang wisata. Di sisi lain, adanya aktivitas wisata tersebut tentu akan memengaruhi aktivitas pertanian dan dapat berdampak pada sumber nafkah petani. Penelitian ini menggunakan pendekatan mixed-method untuk melihat hubungan antar variabel. Hubungan antar variabel ini secara statistik diolah menggunakan uji korelasi Rank Spearman dengan jumlah responden sebanyak 35 rumah tangga petani. Hasil penelitian yang diperoleh menunjukan bahwasanya setelah adanya pengembangan agrowisata terjadi perubahan kepemilikan modal nafkah pada modal alam, modal fisik, modal manusia dan modal finansial. Selain itu, perubahan juga terjadi pada strategi nafkah yang mereka lakukan. Hal tersebut menyebabkan perubahan struktur nafkah rumah tangga petani, karena adanya proposi sumber nafkah baru dari sektor pariwisata., The agricultural sector is used not only to produce food or industrial raw materials but also as a means of tourism and educational activities. Tourism activities that utilize agricultural land are called agrotourism. The presence of agro-tourism brings many positive impacts for the community around tourist attractions, such as improving the community's economy because of the absorption of labor for the tourism sector. On the other hand, the existence of tourism activities will certainly affect agricultural activities and can have an impact on farmers' livelihoods. This study uses a mixed-method approach to see the relationship between variables. The relationship between these variables was statistically processed using the Spearman Rank correlation test with the number of respondents as many as 35 farmer households. The results obtained indicate that after the development of agro-tourism there is a change in the ownership of livelihood capital in natural capital, physical capital, human capital and financial capital. In addition, changes also occur in their livelihood strategies. This causes changes in the structure of farmer household livelihoods, due to the proportion of new sources of income from the tourism sector.

Judul: The Relationship between Participation of Commmunity in Ecotourism Development and control of Livelihood Assets
Abstrak: Pariwisata merupakan sektor yang sangat menjanjikan dalam mengembangkan suatu wilayah. Ekowisata menyuguhkan pengembangan pariwisata berkelanjutan dengan tujuan mendukung upaya-upaya pelestarian dan meningkatkan partisipasi masyarakat dalam pengelolaannya. Peran dan partisipasi masyarakat sangat dibutuhkan dalam proses pengembangan kegiatan ekowisata. Partisipasi masyarakat dalam kegiatan ekowisata dapat menentukan penguasaan livelihood assets yang terdiri dari lima aset nafkah yaitu modal alam, modal manusia, modal sosial, modal finansial, dan modal fisik. Tujuan penelitian ini adalah untuk mengkaji hubungan antara tingkat partisipasi dengan penguasaan livelihood assets. Penelitian ini dilaksanakan di Desa Bangsring menggunakan metode penelitian kuantitatif yang didukung dengan data kualitatif. Teknik pengambilan data melalui kuesioner untuk mendapatkan data kuantitatif dengan teknik sampel aksidental dan wawancara mendalam untuk mendapatkan data kualitatif. Jumlah responden dalam penelitian ini adalah 30. Hasil penelitian menunjukkan bahwa terdapat hubungan antara partisipasi masyarakat dengan elemen-elemen dalam livelihood assets yakni modal manusia, modal sosial, dan modal finansial dalam pengembangan ekowisata., Tourism is of a very promising sector in developing a region. Ecotourism presents the development of sustainable tourism with the aim of supporting conservation and increasing the participation of community in its management. The role and participation of community are needed in the development of ecotourism. Participation of community in ecotourism activities may influence the control of livelihood asset which consist of five assets, namely natural capital, human capital, social capital, financial capital, and physical capital. The purpose of this research is to examine the relationship between level participation of community and control of livelihood assets.

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.
