Judul: Analisis persepsi dan preferensi pengunjung serta dampak ekonomi kegiatan wisata gunung salak endah
Abstrak: Kawasan GSE adalah kawasan yang mempunyai banyak sumberdaya yang dapat dikembangkan menjadi obyek wisata yang menarik. Daya tarik GSE berupa keindahan alam, dan keanekaragaman hayati merupakan modal dasar dalam pengelolaan wisata dan mendukung keberhasilan pengembangan bidang wisata alam. Peresmian kawasan GSE sebagai kawasan wisata mendatangkan dampak tersendiri bagi masyarakat sekitar. Masyarakat mengalami peningkatan perekonomian, seperti peningkatan pendapatan, peningkatan kesempatan kerja dan peluang usaha. Contohnya, mereka dapat menciptakan lapangan kerja baru dengan membuka kios makanan dan minuman, pedagang asongan dan menjadi pemandu parkir.

Judul: Dampak Kegiatan Wisata Alam Kawasan Gunung Salak Endah terhadap Kondisi Sosial Ekonomi Masyarakat
Abstrak: Gunung Salak Endah (GSE) was a production and protection forest areas managed by Perum Perhutani prior to its establishment as Gunung Halimun Salak National Park in 2003. Its function change had brought some consequences on the social and economic conditions of the local communities. Analysis on these impacts was necesary to observe the benefits on the communities. The main objective of this research was to analyze the impacts of the area function change on the social and economic conditions of the local communities. The research was conducted at Gunung Bunder 2 Village and Gunung Sari Village. Interviews, questioners, and observation were used in the research methodology. As many as 100 households that were involved in tourism activities and 30 households that were not involved in tourism activities. Were interviewied result of the analysis showed that types of community trade and service were dominated by tourism service (84%) and 16% by tourism infrastructure. They involve at tourism trade and service which 70% by individual efforts; with intensity that always involve. 20% involved by tourism organized and involved by family. The function change into a protected area has increased the community awareness on the sustainability, totality and beauty of area. Effect of area function change to tourism exertion which been operated by communities include new restriction and construction of infrastructure. The service exertion of community and infrastructure still can operate in the areas. These tourism activities at GSE give some effect to social economic condition. There were positive impacts towards openness to stranger and funding, but negative impacts to the community social condition with demonstration effect to the teenage as the most appeal, social conflict, change of time work allocation, social activities and norm of decency reduction. The economic impacts that occurred in both villages were: the availability of job and trade opportunites, economic mobility and increasing of community income. Tourism activities has contributed an average of 62% to the household total income.

Judul: Klasifikasi Protein Family Menggunakan Metode Rantai Markov
Abstrak: Proteins are large biological molecules that consist of one or more chains of 20 amino acids sequences. Proteins have various functions such as catalyzing metabolic reactions, replicating DNA, and transporting molecules. Many new protein sequences have been found. Therefore, a new method is required to classify proteins which have similar amino acids sequence, structure and function into the same class. The aim of this research is to apply Markov chain concept for protein family classification based on amino acid sequences. Protein data samples are obtained from Pfam protein family database website. Samples are taken from three different protein family classes, namely: 1-cysPrx_C, 4HBT and ABC_Tran, 100 data samples each. This research utilizes two different extraction methods: first order and second order Markov chain. First order indicates that the data sequence stored in the transition matrix is every two adjacent sequences, while the second order indicates that the data sequence stored in the transition matrix is every two sequences that are intermittent twice. The results show that the first order method gives 96% as its best accuracy, whereas the second order method gives 89.33% as its best accuracy
