Judul: Evaluasi Penerapan Indeks Kinerja Lingkungan dan Konsep Kota Hijau di Kota Bogor.
Abstrak: Urbanisasi di Kota Bogor yang berkembang pesat berdampak pada penurunan kualitas lingkungan. Oleh karena itu diperlukan suatu konsep perencanaan kota yang berkelanjutan. Tujuan penelitian ini adalah membandingkan indeks kinerja lingkungan tentang konsep Kota Hijau di dunia dan mengevaluasi kinerja lingkungan Kota Bogor. Evaluasi kinerja lingkungan dilakukan dengan menggunakan 8 kategori dari Asian Green City Index yaitu Energi dan CO2, Penggunaan Lahan dan Bangunan, Transportasi, Sampah, Air, Sanitasi, Kualitas Udara dan Tata Kelola Lingkungan. Penelitian ini menggunakan metode kuantitatif dengan analisis deskriptif. Hasil yang didapatkan adalah rata-rata keseluruhan kinerja Kota Bogor dalam mewujudkan konsep Kota Hijau termasuk dalam nilai diatas rata-rata atau kategori baik (63.06%). Kinerja terendah adalah kategori energi dan CO2 (48.75%), penggunaan lahan dan bangunan (51.75%), kualitas udara (53.5%), sampah (58.5%) dan kinerja terbaik adalah kategori tata kelola lingkungan (88.11%).

Judul: Evaluasi Penerapan Konsep Kota Hijau di Kota Bogor
Abstrak: Development of urban areas in Indonesia is very rapid. City is a reflection of local environment condition, citizen behavior and local culture. Activity and development of the city will cause of various environmental problems like the imbalance between urban growth and the improvement of environmental quality. It bring about the city become not liveable. Because of that is very important to create a comfortable city with safety guarantee and be the one with nature by applying the concept of green city. Green city is a concept of a healthy city, considering ecological aspects. This research use Gap Analysis to find out the actual condition of Bogor City and compare it with the ideal condition of green city concept and evalauate the implementation with scoring method. The results of this research showed that Bogor has had a city development plan towards sustainable city, but the implementations still have not been maximized. The implementations not been spread through the region and have not been solve the urban problems of Bogor City.

Judul: The Exploration of Discrete Logarithm over Finite Field GF(3m)
Abstrak: The security of many public~key algorithms is based on the problem of finding discrete logarithms. The generalized discrete logarithm problem is the following: given a finite cyclic group G of order n, a generator a of G, and an element fl E G, find the integer x, 0 ~ x ~ n - 1, such that 0: = fl. Algorithm for discrete logarithm problem focused on Menezes et al. (1997) that consist of exhaustive search algorithm, the baby-step giant-step algorithm, Pollard's rho algorithm, Pohlig-Hellman algorithm, and index-calculus algorithm. These algorithms are explorated to be used in discrete logarithm problem over finite field GF(3m ). The exploration also produces some algorithms, i.e. naif negative algorithm, baby-step mother-step algorithm, baby-step mother free-step algorithm, and baby-step free-step algorithm. All algorithms implemented using Maple 11. The Pohlig-Hellman and baby-step giant-step algorithms are efficient enough to be used in discrete logarithm problem over finite field GF(3m ) for m < 20.
