Judul: Khasiat Antiinflamasi Ekstrak Herba Suruhan (Peperomia pellucida [L]) dan Campurannya dengan Jahe Merah (Zingiber officinale Rosc.) pada Tikus
Abstrak: Suruhan herb has been reported for its anti-inflammatory activity, but its usage are still limited. Besides suruhan herb, the other plant which can be used as anti-inflammatory drugs is red ginger. The objective of this research was to test the effectivity of the formula mixture of suruhan herb and red ginger extracts as anti-inflamation in vivo. A total of 24 male white Wistar strain rats were divided into six groups: the control group (CMC 0.5%), the sodium diclofenac (1.25 mg/kg BB), the suruhan herb (100 mg/kg BW), the suruhan herb (117.5 mg/kg BW), the formula 1 extract, and the formula 2 extract. The volume of the rats carrageenan-induced foot paw was measured using plethysmometer for six hours. The results showed that carragenan-induced increased the foot paw of rats. Eventhough data were not statistically significant, suruhan herb-ginger extract tended to reduce inflammation in vivo. The effect was the same as the commercialized anti-inflammatory drugs natrium diclofenac and was better than the single extract. The percentage of inflammatory inhibition of formula 1 was 33.69% and formula 2 was 28.31%. Moreover, mixture of suruhan herb-ginger extract reduced leukocytes level more than natrium diclofenac.

Judul: Khasiat Losion Antiinflamasi Campuran Nanopartikel Jahe Merah (Zingiber officinale Var Rubra) dan Suruhan (Pepperomia pellucida) pada Edema Kaki Tikus
Abstrak: Jahe merah ( Zingiber officinale Var Rubra) dan Suruhan (Pepperomia pellucida) merupakan tanaman yang telah dilaporkan memiliki khasiat sebagai antiinflamasi. Penelitian ini bertujuan menentukan konsentrasi campuran nanopartikel jahe merah dan suruhan terbaik sebagai antiinflamasi dalam bentuk sediaan losion sehingga dapat menggantikan sediaan antiinflamasi nonsteroid sintetik. Sebanyak 30 ekor tikus jantan galur Sprague Dawley dibagi ke dalam enam kelompok: 1) kontrol karagenan (losion blanko), 2) diklofenak (1%), 3) nanolosion 10 %, 4) nanolosion 17.5 %, 5) nanolosion 35 %, dan 6) losion ekstrak 35 %. Volume edema kaki tikus yang diinduksi oleh karagenan 1% diukur setiap jam selama 6 jam menggunakan pletismometer. Hasil penelitian menunjukkan bahwa nanolosion 17.5% yang mengandung nanopartikel jahe merah dan suruhan (2:1) menghasilkan khasiat antiinflamasi terbaik. Nanolosion tersebut memiliki daya antiinflamasi sebesar 48.41%. Daya antiinflamasi nanolosion 17.5 % tidak berbeda nyata dengan losion ekstrak kasar 35 % maupun sediaan antiinflamasi sintetik yang umumnya dipakai oleh masyarakat (P<0.05).

Judul: Eksplorasi Masalah Logaritma Diskret pada Finite Field G P(2m)
Abstrak: Discrete logarithm problem represents a problem which is defined as modular arithmetic. It is often used to generate a key pair on public key cryptography as security object. Given cyclic group G of order n, αgenerator of G, and β∈􀜩, then, in general, discrete logarithm problem is determined as the integer 􀝔, 0≤􀝔≤􀝊−1, such that α􀯫≡β(mod 􀝊). In Menezes et al. (1997) the algorithm to solve the discrete logarithm problem in common cyclic group G are Exhaustive Search algorithm, Baby-Step Giant-Step, Pollard's rho, Pohlig Hellman and Index Calculus. Furthermore, these algorithms are explored to determine the solution of discrete logarithm problem on 􀜩􀜨(2􀯠). The reconstructed algorithms are implemented using Maple 11 software. These implementation can be used to measure security level of cryptography algorithm, which is based on security aspects of discrete logarithm problem
