Judul: Respon Stakeholders terhadaap Pengolahan Konservasi Bersama Masyarakat di Wilayah Perluasan Taman Nasional Gunung Gede Pangrango
Abstrak: Perluasan kawasan Taman Nasional Gunung Gede Pangrango merubah paradigma baru pengelolaan kawasan hutan dengan melibatkan masyarakat. Pengelola TNGP membentuk suatu kegiatan pengganti PHBM, yaitu Pengelolaan Konservasi Bersama Masyarakat (PKBM) yang merubah pola tanam sayuran menjadi penanaman pohon untuk merehabilitasi hutan dan memberikan alternatif pekerjaan bagi masyarakat. Dalam pelaksanaannya, kerja sama antara para pihak yang terkait sangat diperlukan agar kegiatan ini berjalan secara optimal. Untuk itu diperlukan suatu upaya pengkajian PKBM yang mewakili aspirasi seluruh stakeholder sebagai landasan untuk mengembalikan fungsi kawasan konservasi dan meningkatkan kesejahteraan masyarakat.

Judul: Kinerja Program Pemberdayaan Kelompok Tani Hutan Terhadap Keberhasilan Tujuan Konservasi di Taman Nasional Gunung Gede Pangrango.
Abstrak: Taman Nasional Gunung Gede Pangrango membentuk Kelompok Tani Hutan untuk mengurangi konflik dengan masyarakat. Tujuan penelitian ini adalah menilai dampak program ekonomi, sosial budaya dan ekologis KTH Hejo Cipruk, menilai keberhasilan program KTH berdasarkan tujuan konservasi dan menilai faktor-faktor yang mempengaruhi keberhasilan KTH Hejo Cipruk secara fungsional dan structural di Desa Gekbrong. Penelitian ini menggunakan metode wawancara, observasi lapang, dan studi literatur. Anggota KTH setuju dengan adanya program KTH berdampak pada meningkatkan pendapatan ekonomi, meningkatkan pengetahuan, partisipasi dan keterampilan anggota KTH dan kepedulian terhadap lingkungan. Manfaat ekonomi yang didapatkan anggota KTH adalah mendapat bantuan berupa green house dari pihak TNGGP untuk budidaya pengolahan berbahan dasar sayuran, dan bertambahnya sumber pendapatan dari jasa penginapan homestay. Berdasarkan aspek konservasi anggota KTH berhasil meninggalkan kawasan dan melakukan rehabilitasi kawasan TNGGP yang semula lahan pertanian dan perkebunan menjadi hutan kembali.

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
