Judul: Quantifying of Ecosystem Services in the Aspect of Climate Regulation in Komodo National Park
Abstrak: Taman Nasional Komodo merupakan taman nasional tertua sekaligus cagar biosfer dunia karena keunikannya terdapat hewan langka komodo (Varanus komodoensis) serta keindahan alam maupun keanekaragam hayati perairannya membuat tempat ini sebagai tujuan ekowisata dunia. Pengembangan ekowisata merupakan salah satu upaya Pemerintah dalam meningkatkan minat pariwisata. Namun, perkembangan ekowisata akan mempengaruhi kebijakan penggunaan lahan yang berimplikasi pada jasa lingkungan. Penelitian ini bertujuan mengkuantifikasi jasa lingkungan yang terdapat di Taman Nasional Komodo dalam aspek pengaturan, khususnya pengaturan iklim seperti penyerapan karbon. Metode yang digunakan adalah metode maximum likelihood dalam mengklasifikasi tutupan lahan dan pendekatan efisiensi penggunaan radiasi untuk perhitungan karbon. Hasil penelitian menunjukkan bahwa terjadi perubahan tutupan lahan seluas -3575,2 ha (-22,03%) hutan kering sekunder, -1142,3 ha (-5,27%) savana, dan peningkatan lahan terbuka sebesar 4777,6 ha (35,64%). Suhu permukaan tertinggi di daerah penelitian terjadi pada tahun 2019 baik pada bulan Maret-April dan Agustus-September masing-masing sebesar 24,46oC dan 27,66oC yang juga dipengaruhi oleh fenomena ENSO yaitu El-Nino. Potensi penyerapan karbon di Taman Nasional Komodo lebih tinggi pada periode Maret-April dibandingkan periode Agustus-September. Pasalnya, pertumbuhan savana yang didominasi kawasan ini tumbuh subur dengan cepat. Jumlah penyerapan karbon tertinggi terjadi pada tahun 2018 sebesar 2.368,8 Megaton/tahun., Komodo National Park is the oldest national park as well as the world's biosphere reserve because of its uniqueness there are rare Komodo dragons (Varanus komodoensis) and the natural beauty and biodiversity of its waters make this place a world ecotourism destination. The development of ecotourism is one of the Government's efforts to increase tourism interest. However, the development of ecotourism will affect land use policies which have implications for environmental services. This study aims to quantify the environmental services in Komodo National Park in terms of regulation, particularly climate regulation such as carbon sequestration. The method used is the maximum likelihood method in classifying land cover and the radiation use efficiency approach for carbon calculations. The results showed that there was a change in land cover of -3575.2 ha (-22.03%) secondary dry forest, - 1142.3 ha (-5.27%) savanna, and an increase in open land of 4777.6 ha (35 ,64%). The highest surface temperature in the study area occurred in 2019 in March-April and AugustSeptember respectively at 24.46oC and 27.66oC which was also influenced by the ENSO phenomenon, namely El-Nino. The potential for carbon sequestration in Komodo National Park is higher in the March-April period than the August-September period. The reason is, the growth of the savanna which is dominated by this area is growing rapidly. The highest amount of carbon sequestration occurred in 2018 at 2,368.8 Megatons/year.

Judul: Analysis of Stakeholder Acceptance of Development Adaptive Ecotourism (Case Study: Komodo National Park)
Abstrak: Perkembangannya pariwisata menghadapi masalah yang juga dihadapi sektor-sektor lain, yaitu pandemi Covid-19 salah satu stategi yang dapat diterapkan dalam mengahdapi masalah ini adalah adaptive ecotourism. Penelitian ini bertujuan mengidentifikasi keberterimaan serta peluang dan kendala dari Stakeholder terhadap pengembangan adaptive ecotourism serta merumuskan strategi pengembangan di Taman Nasional Komodo. Metode pengambikan data yang digunakan dalam penelitian ini adakah Focus Grup Discussion dan wawancara. Taman Nasional Komodo adalah kawasan yang sudah banyak dikenal oleh wisatawan domestik maupun mancanegara karena memiliki ciri khas yang khusus yaitu dan juga merupakan kawasan yang ditetapkan sebagai warisan dunia. Pengembangan pariwisata dengan konsep adaptive ecotourism memerlukan pembangunan yang dapat mendukung berjalannya kegiatan bekerja dan belajar di kawasan. Peraturan perundangan yang mengatur pembangunan dalam kawasan sudah diatur oleh kementerian sehingga kegiatan pemanfaatan kawasan dapat dilakukan secara optimal. kegiatan belajar diakawasan yang dapat dilakukan oleh sekolah yang berada disekitar kawasan sebelumnya belum banyak dilakukan hal ini perlu dikembangkan lagi agar kegaitan belajar dikawasan dapat dilaksanakan dengan. Dari analisis Swot yang telah dilakuakn strategi pengembangan yang perlu diperhatikan adalah strategi WT atau damage control dengan meminimalkan kelemahan dan menghindari ancaman., Tourism development faces problems that are also faced by other sectors, namely the Covid-19 pandemic, One of the strategies that can be applied in dealing with this problem is adaptive ecotourism.. This study aims to identify acceptability, opportunities, and constraints from stakeholders on the development of adaptive ecotourism and formulate development strategies in Komodo National Park. The data collection method used in this research is Focus Group Discussion and interviews. Komodo National Park is an area that is already widely known by domestic and foreign touristsuse havec the special characteristics of having rare endemic animals and is also an area designated as a world heritage. Tourism development with the concept of adaptive ecotourism requires development that can support work and study activities in the region. The ministry has regulated the laws and regulations governing development in the area so that area utilization activities can be carried out optimally. Learning activities in the area that can be carried out by schools around the area have not previously been done much, this needs to be developed again so that learningactivities in the area can be carried out. From the SWOT analysis, the development strategy that needs to be considered is the WT strategy or damage control by minimizing weaknesses and avoiding threats.

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
