Judul: Visitor Perception about the Potential Development of Eco-edutourism in Pusat Suaka Satwa Elang Jawa
Abstrak: Pusat Suaka Satwa Elang Jawa (PSSEJ) terkenal sebagai suatu kawasan yang digunakan untuk wisata alam, salah satunya wisata alam berbasis pendidikan (eco-edutourism) yang dapat dikembangkan untuk menarik minat masyarakat luas, dan tempat rehabilitasi burung elang hasil penyitaan atau serahan dari masyarakat. Penelitian ini bertujuan untuk mengidentifikasi potensi pengembangan, persepsi pengunjung, dan rencana pengembangan program eco-edutourism. Metode yang digunakan yaitu studi literatur, wawancara dengan panduan wawancara dan kuesioner, serta observasi lapang. Data dianalisis dengan analisis deskriptif untuk mengidentifikasi karakteristik dan persepsi responden, serta uji Chi-Square untuk melihat hubungan antara karakteristik pengunjung dengan persepsi. Penelitian ini mendapatkan 35 individu burung elang, 15 jenis tumbuhan, dan 15 jenis satwa. Potensi fasilitas kawasan adalah akses, papan interpretasi, dan sarana prasarana. Persepsi pengunjung mengenai keempat komponen pernyataan memberikan persentase setuju rata-rata di atas 50%. Hal tersebut menandakan cenderung tergolong baik. Rencana pengembangan program eco-edutourism dipilih melalui pendekatan supply. Keseluruhan konsep terkait program maupun kawasan disediakan oleh pihak pengelola PSSEJ., Pusat Suaka Satwa Elang Jawa (PSSEJ) is known as an area used for natural tourism, educational nature-based tourism (eco-edutourism) that can be developed to attract public interest. This institution also serves as a place to rehabilitate eagles confiscated from or surrendered by the community. This study aimed to identify the potential development of eco-edutourism, visitor perception, and to design eco-edutourism programs. Methods used were literature studies, field observations, questionnaires, and interviews. The data was analyzed using descriptive analysis to identify the characteristics and perception of respondents, and Chi-Square test to determine the relationship between respondents’ characteristics and their perception. The study found 35 individuals of eagle, 15 plant species, and 15 animal species. The potential facilities included access, interpretation board, and supporting infrastructure. The result of the study showed that the visitor perception of four components of the statements had the average percentage of approval above 50%, which indicated a positive perception. The development plan of eco-edutourism program was selected through the supply approach. The whole concept related to the program and the area was provided by the management PSSEJ.

Judul: Ecotourism Landscape Planning for Loji Eagle Sanctuary in the Mount Halimun Salak National Park
Abstrak: Suaka Elang Loji (SEL) merupakan komplek wisata alam yang berada di zona pemanfaatan Taman Nasional Gunung Halimun Salak. Dikenal dengan kekayaan ekosistem dan ragam daya tarik wisata, khususnya Pusat Suaka Satwa Elang Jawa, SEL memiliki potensi pengembangan ekowisata yang bernilai tinggi dan unik. Namun, belum adanya penataan zona khusus rehabilitasi elang, potensi bencana lanskap, serta kurangnya fasilitas dan program wisata dinilai menghambat pengembangan ekowisata yang optimal. Oleh karena itu, penelitian ini bertujuan merencanakan lanskap untuk pengembangan ekowisata SEL yang berkelanjutan. Metode perencanaan lanskap menerapkan analisis spasial dan deksriptif pada aspek fisik-biofisik, sosial-ekonomi, wisata, dan legal dengan menggunakan pendekatan Regional Ecotourism Development Planning. Rencana lanskap menghasilkan konsep ekowisata yang memiliki nilai edukatif dan rekreatif bagi pengunjung. Untuk memenuhi fungsi rehabilitasi, konservasi, dan wisata, lanskap dikembangkan menjadi lima ruang utama yaitu ruang suaka, ruang konservasi, ruang penyangga dan rekreasi terbatas, ruang rekreasi, serta ruang penunjang wisata. Perencanaan ini meliputi rencana ruang, aksesibilitas dan sirkulasi, aktivitas dan fasilitas, vegetasi, serta daya dukung tapak., Loji Eagle Sanctuary is an ecotourism sites within the utilization zone of Mount Halimun Salak National Park. Renowned for its rich ecosystem and various tourist attractions, especially Javan Hawk Eagle Sanctuary Center, Loji Eagle Sanctuary holds high-value and distinctive ecotourism potential. However, the absence of limited zones for eagle rehabilitation, potential of landscape disasters, and the lack of facilities and tourism programs encounter the optimum landscape development. Therefore, this research aims to formulate a landscape plan for sustainable ecotourism development in Loji Eagle Sanctuary. Landscape planning methods apply spatial and descriptive analysis to physical-biophysical, socio-economic, tourism, and legal aspects using Regional Ecotourism Development Planning approach. The landscape plan produces an ecotourism concept with educational and recreational value for visitors. To fulfill the functions of rehabilitation, conservation, and tourism, the landscape is developed into five main zones, specifically the sanctuary zone, conservation zone, buffer and limited recreation zone, recreation zone, and tourism development zone. This plan includes a spatial plan, accessibility and circulation plan, activities and facilities plan, vegetation plan, also site carrying capacity plan.

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
