Abstrak: Soybean is one of the vegetable protein sources that important and economical. In addition to a high protein, soy is also rich in vitamin and mineral. One of the soy product is fermented with Rhizopus sp. is tempe. The fermentation process make soybean components simpler and increase nutrient content in tempe. High nutrient content in tempe and soybean make these commodities consumed by societies. This study aims to evaluate blood hematology (hemoglobin, erythrocyte, leukocyte, platelet and hematocrit), serum profiles (blood glucose, cholesterol, triglycerides, high density lipoprotein, low density lipoprotein, ureum, uric acid, SGOT, SGPT, protein total and albumin), superoxide dismutase (SOD) and malonaldehide (MDA) of liver and kidney after consuming tempe flour and boiled soybean flour during treatment. This study using three group of rats that casein 10 %, tempe flour 10 % and boiled soybean flour 10 %. Analysis of serum profile, hematology, SOD and MDA proving consumption of boiled soy and tempe are good to be consumed in the long time.

Abstrak: Tempe is a derived product from soybean fermentation, which relatively had a short shelf life. An effort to extend the shelf life of tempe has been done by making tempe flour. Difference of raw materials which were GMO and non-GMO was pressured to cause different impact on human health. Thus, this study was conducted to evaluate the effect of tempe flour that were made from GMO and non-GMO soybean upon malonaldehida levels, intracellular antioxidant superoxide dismutase activity in the liver and kidneys of experimental rats, as well as hematological profile. The results showed that rats fed with 10% protein drived from non-GMO soybean flour had lower levels of MDA in the liver and kidney compared to GMO tempe flour group consisting rations of 10% and 20% protein but, not significantly different from the group protein of 20% non-GMO soybean flour and 10% protein of casein. While the value of liver and kidney SOD activity were not significantly different (p>0,05) between the groups of rats. In hematology, the results showed that the values obtained were within normal limits. However, the amount of rat’s thrombocyte measured in each treatment had a value that exceeds normal limits. It was caused by several factors, which were the activity of rat, rat’s metabolism, and amount of feed intake by rats. Results of MDA, SOD, and hematology examination showed that consuming non-GMO and GMO tempe flour were safe for consumption.

Judul: Closed Knight’s Tour pada Papan Catur Berbentuk Persegi Panjang dengan Ukuran Maksimal 8 × 8
Abstrak: Closed Knight’s Tour merupakan langkah kuda yang mengunjungi setiap kotak pada papan catur tepat satu kali dengan langkah kuda berawal dan berakhir pada kotak yang sama. Graf yang terbentuk dari closed knight’s tour dinotasikan sebagai graf G(m,n), dengan m adalah banyaknya baris dan n adalah banyaknya kolom. Graf tersebut memuat Hamiltonian cycle. Sebuah graf terhubung G adalah graf bipartite jika dan hanya jika graf tersebut tidak memiliki cycle dengan panjang ganjil. Papan catur yang memenuhi syarat cukup untuk memiliki closed knight’s tour adalah papan catur berukuran 5 × 6, 5 × 8, 6 × 6, 6 × 7, 6 × 8, 7 × 8, dan 8 × 8.
