Judul: Histopathological Features and Tissue  Regeneration Ability of Third Degree Burns in White Rats (Rattus norvegicus)
Abstrak: Luka bakar merupakan suatu jenis trauma akibat adanya kontak dengan api, air panas, bahan kimia, listrik, dan radiasi. Luka bakar terdiri dari derajat I (superfisial), IIa (ketebalan parsial), IIb (ketebalan parsial dalam), III (ketebalan penuh), dan IV (hangus). Penelitian ini bertujuan mengetahui proses terjadinya dan persembuhan luka bakar derajat III secara makro dan mikroskopik (patologi anatomi dan histopatologi). Penelitian ini menggunakan empat tikus, tiga tikus sebagai kontrol positif dan satu tikus sebagai kontrol negatif. Parameter yang diamati adalah luas area luka bakar dan jumlah sel radang selama 14 hari. Hasil data diolah menggunakan software Fiji ImageJ windows 64, Microsoft Excel, SPSS dengan metode One-Way ANOVA, dan Uji Duncan. Hasil penelitian luka bakar derajat III menunjukkan kerusakan seluruh epidermis, dermis, dan hipodermis, tidak dijumpai lepuh, kulit berwarna putih dan pucat, dan mengalami proses regenerasi lebih dari 14 hari. Proses regenerasi luka berjalan seiring dengan perubahan luas luka yang mengecil dan perubahan jumlah sel radang yang lebih sedikit., Burns are traumas caused by fire, hot water, chemicals, electricity and radiation. Burns consist of degrees I (superficial), IIa (partial thickness), IIb (deep partial thickness), III (full thickness), and IV (charred). This study aims to inform the process of occurrence and healing of third degree burns from a macro and microscopic perspective (anatomical pathology and histopathology). This study used four rats, three rats as positive controls, and one rat as negative control. The parameters observed the area of the burn wound and the number of inflammatory cells for 14 days. The data results processed using Fiji ImageJ Windows 64 software, Microsoft Excel, SPSS with One-Way ANOVA method, and the Duncan test. The results of research on third degree burns showed damage to the entire epidermis, dermis, and hypodermis, no bullae were found, the skin was white and pale, and the regeneration took more than 14 days. The process of wound regeneration goes conjointly with changes in the area of the wound which becomes smaller and the number of inflammatory cells decreases.

Judul: Effectiveness of Pangasius sp. Skin Collagen Extract in Accelerating Burn Healing in Mice (Mus musculus) In Vivo
Abstrak: Penyembuhan luka bakar menggunakan ekstrak kolagen dari kulit ikan sedang mengalami trend. Pada penelitian ini yang digunakan adalah ekstrak kolagen kulit ikan patin (Pangasius sp). Uji in vitro menunjukkan ekstrak kolagen kulit ikan patin memiliki sifat anti-inflamasi yang menjanjikan dalam pengobatan, namun belum ada yang fokus pada uji in vivo. Oleh karena itu, pada penelitian ini menggunakan metode in vivo untuk menentukan efektivitas ekstrak kolagen kulit ikan patin dalam mempercepat penyembuhan luka bakar derajat II pada mencit. Ekstrak gel kolagen kulit ikan patin dibagi menjadi dua konsentrasi, yaitu 10% dan 15% dengan menggunakan Bioplacenton® sebagai kontrol positif dan kontrol tanpa perlakuan apapun. Data penelitian diukur menggunakan software Image J dan dianalisis menggunakan Rstudio. Hasil penelitian menunjukkan bahwa ekstrak gel kolagen kulit ikan patin konsentrasi 15% memiliki efektivitas yang sama dengan Bioplacenton® dalam mempercepat penyembuhan luka bakar derajat II yang ditandai dengan berkurangnya luas area luka bakar yang berbeda secara signifikan dari kelompok kontrol (p=6.10-1). Hasil histopatologi pada hari ke 14 pasca luka, untuk semua kelompok perlakuan telah mencapai tahap maturasi yang ditandai dengan terbentuknya epitel kulit yang hampir sempurna, sel-sel radang yang mulai berkurang, dan adanya pelengkap kulit. Berbeda dengan pembentukan jaringan epitel pada kelompok kontrol yang masih terlihat terbuka dan belum ditemukannya pelengkap kulit. Namun, secara statistik tidak menunjukkan adanya perbedaan signifikan antar kelompok pada setiap hari pengamatan (p>0.05). Sedangkan pengamatan histokimia menunjukkan adanya perbedaan yang signifikan terhadap pertumbuhan luasan kolagen antara kelompok kontrol dengan kelompok kontrol positif (p=0.04) dan yang diberikan kolagen 15% (p=0.03) pada hari ke-14. Sehingga dapat disimpulkan bahwa pengunaan ekstrak gel kolagen kulit ikan patin mampu mencegah terjadinya hemoragi, mengurangi peradangan, mempercepat reepitelisasi, dan memproduksi matriks ekstraseluler (ECM)., Healing burns using collagen extract from fish skin is becoming a trend. This research used the skin collagen extract of Pangasius sp. In vitro tests show Pangasius sp. skin collagen extract has promising anti-inflammatory properties in medicine, but people have yet to focus on in vivo tests. Therefore, this study used in vivo methods to determine the effectiveness of Pangasius sp. skin collagen extract in accelerating the healing of second-degree burns in mice. Pangasius sp. skin collagen gel extract was divided into two concentrations, such as 10% and 15%, using Bioplacenton® as a positive control and a control without any treatment. Research data was measured using Image J software and analyzed using Rstudio. The results showed that Pangasius sp. skin collagen gel extract with a concentration of 15% had the same effectiveness as Bioplacenton® in accelerating the healing of second-degree burns, which was characterized by a reduction in the area of the burn, which was significantly different from the control group (p=6.10-1). The histopathology results on day 14 after injury, for all treatment groups, had reached the maturation stage, characterized by the formation of almost perfect skin epithelium, inflammatory cells starting to decrease, and the presence of skin appendages. This differs from the epithelial tissue formation in the control group, which still looks open, and no skin appendages have been found. However, statistically, there were no significant differences between groups on each day of observation (p>0.05). Meanwhile, histochemical observations

Judul: Implementasi Algoritme Enkripsi Advanced Encryption Standard secara Paralel dengan GPU NVIDIA CUDA
Abstrak: Processor streaming architecture in GPU has provide general purpose computation which have its own potential to help CPU with its parallel computation capability. One example of supported processor streaming architecture is Fermi which is developed by NVIDIA. Furthermore, NVIDIA has developed its own software development kit namely CUDA, which can integrate many popular existing programming languanges such as C++ for GPU-based parallel computation. This research focus on the implementation of parallel AES algorithm with GPU and analyze the performance result of the implementation in two different NVIDIA devices, namely NVIDIA GeForce GT220 and NVIDIA Quadro 600. In general, the performance of parallel GPU computation is better than sequential computation for large data input. It is obtained that the maximum speedup of NVIDIA GeForce GT220 in 8 MB input is 89.3 with 180% efficiency. Higher speedup of 101.6 can be obtained by NVIDIA Quadro 600 with the same input size with around 100% efficiency.
