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: 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: Implementasi Space Time Composite (STC) Data Model Menggunakan Model Data Relasional
Abstrak: The data model is a concept that describes the data stored in the database and the relationship between the data to the user in logic. Development of data models is very important in the design of the database as the basis of the stage of database design to be made. This study aims to apply the concept of Space Time Composite (STC) on the Model Data storage vector data types that can store enough information and describes the process of drafting objects and objects spatiotemporal evolution over time. From the results of the test queries on the data model that have been created, queries in a system are acquired that can help display the information preparation of objects from time to time and know the history of the object polygon and arc that has undergone changes in topology.
