ABSTRAK Latar Belakang: Kebiasaan masyarakat Indonesia menggunakan obat-obatan yang mudah didapat seperti parasetamol, dimana parasetamol dijual secara bebas akan menyebabkan penyalahgunaannya menjadi lebih besar.Penyalahgunaan ini berakibat timbulnya efek samping  seperti efek hepatotoksik yang menimbulkan kerusakan pada sel-sel hati. Pengendalian efek hepatotoksi didalam tubuh dapat dibantu dengan mengkonsumsi makanan yang mengandung antioksidan. .Ekstrak daun kluwih (Artocarpus camansi) memiliki kandungan antioksidan seperti flavanoid yang diyakini dapat menurunkan aktivitas SGPT dan mengurangi efek toksisitas hepar oleh parasetmol. Tujuan: Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian ekstrak daun kluwih (Artocarpus camansi) terhadap penurunan aktivitas SGPT  tikus putih (Rattus norvegicus) jantan galur Wistar yang diinduksi parasetamol. Metode: Merupakan post-test only control group mengunakan hewan coba tikus putih jantan galur Wistar yang dikelompokkan menjadi 3 kelompok yaitu kelompok kontrol (-), kelompok kontrol (+), kelompok perlakuan yang mendapat terapi ekstrak daun kluwih (Artocarpus camansi) 500 mg/Kg BB Hasil: Hasil penelitian menunjukkan pemberian ekstrak daun kluwih (Artocarpus camansi) dosis 500 mg/kg/BB/hari pada tikus tidak menurunkan secara bermakna aktivitas SGPT pada kelompok tikus yang diberi parasetamol dosis tinggi ( p=0,401 α=0,05) Kesimpulan: Parasetamol dosis tinggi meningkatkan secara bermakna aktivitas SGPT tikus putih (Rattus norveicus) galur Wistar. Pemberian ekstrak daun kluwih (Artocarpus camansi) pada aktivitas SGPT tikus putih (Rattus norveicus) galur Wistar menurunkan  secara tidak bermakna.

Heavy Training

Overtraining syndrome is a decrease in physical capacity, emotions and immunity due to training that is too often without adequate periods of rest. Overtraining is often experienced by athletes who daily undergo heavy training with short break periods. This research aims to look at the effect of overtraining aerobic physical exercise on memory in mice. The research method was experimental in vivo with the subject of adult male rat (Rattus Norvegicus) Winstar strain aged 8-10 weeks, body weight 200-250 gr. Divided into three groups, namely the control group, aerobic group and overtraining group. The results of memory tests with water E Maze showed an increase in the duration of travel time and the number of animal errors made by the overtraining group (p = 0.003). This study concludes that overtraining aerobic physical exercise can reduce memory in rat hippocampus.

Abstract The tire technology related with the computational mechanics is reviewed from the standpoint of yesterday, today, and tomorrow. Yesterday: A finite element method was developed in the 1950s as a tool of computational mechanics. In the tire manufacturers, finite element analysis (FEA) was started applying to a tire analysis in the beginning of 1970s and this was much earlier than the vehicle industry, electric industry, and others. The main reason was that construction and configurations of a tire were so complicated that analytical approach could not solve many problems related with tire mechanics. Since commercial software was not so popular in 1970s, in-house axisymmetric codes were developed for three kinds of application such as stress/strain, heat conduction, and modal analysis. Since FEA could make the stress/strain visible in a tire, the application area was mainly tire durability. Today: combining FEA with optimization techniques, the tire design procedure is drastically changed in side wall shape, tire crown shape, pitch variation, tire pattern, etc. So the computational mechanics becomes an indispensable tool for tire industry. Furthermore, an insight to improve tire performance is obtained from the optimized solution and the new technologies were created from the insight. Then, FEA is applied to various areas such as hydroplaning and snow traction based on the formulation of fluid–tire interaction. Since the computational mechanics enables us to see what we could not see, new tire patterns were developed by seeing the streamline in tire contact area and shear stress in snow in traction.Tomorrow: The computational mechanics will be applied in multidisciplinary areas and nano-scale areas to create new technologies. The environmental subjects will be more important such as rolling resistance, noise and wear.

Daun Kelor (Moringa oleifera L.) secara empiris digunakan oleh masyarakat sebagai antidiabetes. Penelitian ini  bertujuan untuk menentukan pengaruh pemberian ekstrak etanol daun kelor terhadap penurunan kadar glukosa darah tikus putih. Penelitian ini menggunakan 15 ekor tikus jantan yang dibagi menjadi 5 kelompok. Kelompok I merupakan kontrol negatif yang diberikan larutan Na.CMC 1%. Kelompok II, III dan IV adalah kelompok perlakuan yang diberikan ekstrak etanol daun kelor, berurutan, 50, 100, dan 150 mg/Kg BB. Kelompok V merupakan kontrol positif diberikan suspensi glibenklamid®. Sebelum perlakuan tikus dipuasakan selama 18 jam kemudian diinduksi dengan aloksan 150 mg/KgBB. Pengukuran kadar glukosa dilakukan pada hari ke 1, ke 3, ke 5, ke 7 dan ke 9. Hasil penelitian yang dilakukan menunjukkan ekstrak etanol daun kelor dapat menurunkan kadar glukosa darah. Dosis 100 mg/Kg BB memberikan efek penurunan kadar glukosa yang optimal dibandingkan dengan dosis ekstrak lainnya.
