Judul: Analisis Keberterimaan Stakeholders terhadap Konsep Adaptive Ecotourism (Studi Kasus: Taman Nasional Bromo Tengger Semeru, Jawa Timur)
Abstrak: Taman Nasional Bromo Tengger Semeru (TNBTS) pada tahun 2020 mengalami penurunan jumlah kunjungan sampai mencapai 524.691 pengunjung akibat ditetapkannya pandemi Covid-19. Tujuan dari penelitian ini untuk mengidentifikasi keberterimaan serta peluang dan kendala dari stakeholders terhadap Konsep Adaptive Ecotourism serta menganalisis strategi pengembangan ekowisata adaptif di TNBTS. Data dikumpulkan melalui Focus Group Discussion dan wawancara secara virtual kepada para pihak. Data dianalisis menggunakan analisis deskriptif kualitatif dan analisis SWOT. Berdasarkan hasil keberterimaaan para pihak, pengembangan Konsep Adaptive Ecotourism di TNBTS diterima dengan baik, namun masih diperlukan persiapan lebih matang untuk memastikan implementasinya. Hasil analisis dapat disimpulkan bahwa keberterimaan para pihak terhadap pengembangan Konsep Adaptive Ecotourism di TNBTS dinyatakan positif serta Konsep Adaptive Ecotourism dapat dikembangkan di TNBTS dengan memanfaatkan kekuatan TNBTS sebagai faktor internal yang dipadukan untuk menangkap peluang yang ada (faktor eksternal).

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: Algorithm Construction of HLI Hash Function
Abstrak: Cryptography is a study of mathematical techniques related to aspects of information security regarding on confidentiality, data integrity, entity authentication, and data origin authentication. Data integrity is a service, which is associated with the conversion of data carried out by unauthorized parties. To maintain data integrity, one can use hash functions. An hash function is a computationally efficient function to map an arbitrary length bitstring to a fixed length bitstring called as hash value. The use of hash function in maintaining the information integrity and authentication is in digital signatures, virus protection, and software distribution. Illustration of the hash function in the integrity and authentication of information that is emailed as follow. The sender sends the information and hash value to the recipient. If the hash value of the information is equal to the hash value that is sent by the sender, then information has not been changed. Otherwise the information has been changed. An hash function has two properties, one way and collision resistance. An hash function is called one way if it is computationally infeasible to find any input such that when given any hash value . Meanwhile an hash function is called collision resistant if it is computationally infeasible to find any two inputs where such that . The purpose of this study is to construct a HLI hash function algorithm, to analyze the speed and security of the hash functions as a results of construction. Furthermore, it is to compare it with SWIFFT. Hash function is constructed based on the result of algebraic operations on modular polynomial ringwith . Modular polynomial ring noted as is a set of all polynomials of degree at most with coefficients in . can be represented as a set of integer vector of modulo in dimension . So, it is simple to implement in a computer. In vector operations, is lattice . Furthermore, alattice that is defined from certain polynomial ring is called ideal lattice. HLI hash function is consists of addition and multiplication algorithm in the ring. Addition algorithm consists of sumation operations of modulo and multiplication consists of multiplication operations of modulo . Generally, algorithm of HLI hash function consists of multiplication operations of modulo and addition operations of modulo . However, if the input is binary number then multiplication algorithm only consists of multiplication operation of modulo , so algorithm of HLI hash function consists of multiplication operations of modulo and addtion operations of modulo . An hash function is secured if it has two properties, i.e., one way and collision resistance. HLI hash function hash is one way, it is following the proof of Micciancio. It is has collision resistant because of polynomial is irreducible over and monic. Moreover, it is proved that for every unit vector , the vector is small vector. If the input of hash function is a binary number then HLI hash function only involves addition operations of modulo . So the time that used almost same with SWIFFT. The excellence of HLI hash function is the key size smaller than SWIFFT. This effect on
