Judul: Social Economic and Environmental Impacts Ecotourism of Wana Wisata Alam Puncak Angin Development in KPH Sukabumi West Java
Abstrak: Ekowisata merupakan kegiatan pariwisata yang sedang berkembang pesat di Provinsi Jawa Barat akibat perubahan minat masyarakat dari pariwisata yang melibatkan banyak orang menuju wisata minat khusus yaitu wana wisata. Tujuan dari penelitian ini adalah mengetahui pengaruh dampak sosial, ekonomi, dan lingkungan terhadap masyarakat sebelum dan sesudah adanya pengembangan Wana Wisata Alam Puncak Angin. Metode yang digunakan dalam penelitian ini adalah metode analisis deskriptif kuantitatif dan kualitatif. Berdasarkan hasil penelitian dampak sosial dalam indikator tingkat kerja sama menunjukkan adanya peningkatan, namun menaikan tingkat konflik masyarakat dan menurunkan nilai sosial masyarakat karena perubahan gaya hidup anak muda. Pada aspek ekonomi menunjukan bahwa kehadiran ekowisata dapat menyerap tenaga kerja dan merubah mata pencaharian sehingga meningkatkan pendapatan dan tidak meningkatkan pengeluaran biaya eksternal masyarakat yang terkena dampak langsung. Pada aspek lingkungan menunjukkan bahwa masyarakat yang terkena dampak langsung dari wana wisata mengalami peningkatan perubahan sikap pengelolaan hutan dan sampah. Masyarakat yang tidak terkena dampak langsung tidak merasakan adanya perubahan dari aspek ekonomi dan lingkungan., Ecotourism is a tourism activity that is currently growing rapidly in West Java due to the interest shifting of people from mass tourism towards niche tourism, namely Wana Wisata. The purpose of this study was to determine of social, economic, and environmental impacts on the community before and after the development of Puncak Angin ecotourism. This study applied descriptive quantitative and qualitative methods. The results of social impact study indicate that the indicators of community cooperation level are increase, however it increases the level of community conflict and decreases the social value of the community due to lifestyle shifting of young people. On the economic aspect, it shows that the presence of ecotourism can absorb labor and change livelihoods which could increase income and not increase external expenses of the directly affected communities. On the environmental aspect, it shows that people who are directly affected by ecotourism have changed their attitude become aware towards forest and waste management. However, communities who are not directly affected by ecotourism do not perceive any changes from economic and environmental aspects

Judul: Social, Economic, Environmental Impacts  of Sentul Rain Forest Tourism Development, KPH Bogor
Abstrak: Wana Wisata Hutan Hujan Sentul merupakan salah satu objek wisata alam yang dikembangkan di dalam kawasan hutan yang dikelola oleh Perum Perhutani bekerja sama dengan sebuah perusahaan swasta. Penelitian ini bertujuan untuk mengkaji dampak sosial, ekonomi dan lingkungan pengembangan wana wisata tersebut terhadap masyarakat sekitar yang terjadi sebelum dan sesudah adanya wana wisata. Penelitian dilakukan dengan metode analisis kuantitatif dengan wawancara menggunakan bantuan kuesioner. Responden dibagi menjadi dua yaitu masyarakat yang terkena dampak langsung dan tidak langsung. Hasil penelitian menunjukkan bahwa Wana Wisata Hutan Hujan Sentul memberikan dampak positif dari segi sosial yaitu meningkatkan akses jalan sehingga memudahkan mobilitas masyarakat. Pada aspek ekonomi, membuka lowongan pekerjaan dan meningkatkan pendapatan masyarakat. Pada aspek lingkungan, meningkatkan jumlah tutupan pohon dan menyebabkan perubahan sikap masyarakat dalam pengelolaan hutan. Pengembangan Wana Wisata Hutan Hujan Sentul juga memberikan dampak negatif yaitu meningkatkan konflik dan meningkatkan biaya eksternal pada masyarakat yang terkena dampak langsung., Sentul Rain Forest Tourism (SRFT) is one of the ecotourism objects developed in a forest area managed by Perum Perhutani in collaboration with a private company. This study aims to examine the social, economic, and environmental impacts on the surrounding community before and after SRFT development. The research was conducted using quantitative analysis methods with interviews using questionnaires. Respondents were divided into two groups, namely community groups that received direct and indirect impacts. The results show that SRFT has a positive social impact, namely increasing social accessibility which can increase people's mobility. On the economic aspect, SRFT is able to create jobs and increase people's income. On the environmental aspect, it can increase the amount of tree cover and change people's attitudes towards forest management in a positive way. However, the development of SRFT also has a negative impact which are increasing conflict between tourists and the community and increasing the externality costs to community groups that receive direct impacts.

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.
