Judul: Analysis of the Glycemic Index of Eri Puppae Flour Flakes (Samia cynthia ricini) and Its Effect on Rat Blood Hematology
Abstrak: Ulat sutera eri (Samia cynthia ricini) merupakan ternak satwa harapan yang memiliki hasil ikutan berupa pupa yang diketahui memiliki kandungan gizi yang baik seperti protein, karbohidrat, lemak, mineral dan vitamin. Oleh karena itu, pupa eri dalam bentuk tepung berpotensi untuk menjadi salah satu bahan makanan yang baik bagi penderita diabetes. Namun, indeks glikemik dari produk baru ini serta efek sampingnya masih belum diketahui sehingga penelitian ini bertujuan untuk mengukur indeks glikemik dari produk dan perubahan pada hematologi darah yang dapat terjadi menggunakan tikus percobaan. Total tikus yang digunakan adalah 13 ekor tikus putih galur Sprague-dawley dengan konsentrasi tepung pupa eri dalam flakes sebanyak 4% dan 8%. Berdasarkan hasil pengujian indeks glikemik, diperoleh hasil sediaan flakes dengan konsentrasi tepung pupa eri 4% dan 8% adalah sebesar 92,6% dan 75,8%. Uji hematologi lengkap menunjukkan semua parameter sel darah merah dan putih berada pada rentang normal., The eri silkworm (Samia cynthia ricini) is a hopeful animal which has byproducts in the form of pupae which are known to have good nutritional content such as protein, carbohydrates, fats, minerals and vitamins. Therefore, eri pupa in the form of flour has the potential to be a good food ingredient for diabetics. However, the glycemic index of this new product and its side effects are still unknown, so this study aims to measure the glycemic index of the product and changes in blood hematology that can occur using rats. The total number of rats used was 13 white rats of the Sprague-Dawley strain with 4% and 8% concentrations of ery powder in flakes. Based on the results of the glycemic index test, the results obtained for flakes preparations with 4% and 8% erythema powder concentrations were 92.6% and 75.8%. A complete hematology test showed all red and white blood cell parameters within the normal range.

Judul: Microbiological Properties and Antioxidant Activity of Eri Silkworm Pupae (Samia cynthia ricini) Flour with Different Particle Size
Abstrak: Pupa ulat sutra Eri (Samia cynthia ricini) memiliki nilai gizi dan sifat antioksidan yang dapat dijadikan sebagai produk pangan berupa tepung. Sebagai produk pangan, diperlukan uji analisis mikrobiologi sehingga diketahui kelayakannya. Sifat Mikrobiologi dianalisis dengan menghitung Angka Lempeng Total, E. coli, S. aureus dan Salmonella sp. Sementara itu, adanya proses pengayakan tepung dengan tujuan menghomogenkan ukuran partikel dapat memengaruhi aktivitas antioksidan. Maka dari itu, nilai aktivitas antioksidan pada tepung sutra Eri dengan ukuran partikel 80 mesh dan 60 mesh diuji melalui aktivitas penghambatan DPPH (2.2-Diphenyl-1-picrylhydrazyl) dan kapasitas antioksidan. Analisis data menggunakan rancangan acak lengkap (RAL) dan uji T-Independen. Hasil menunjukkan bahwa nilai ALT, E. coli dan Salmonella sp. telah memenuhi ketentuan standar SNI 3751:2009. Jumlah sel S. aureus pada tepung ialah <105 koloni/g, sehingga mengindikasikan bahwa jumlah cemaran tidak melebihi ambang batas. Selain itu, analisis aktivitas antioksidan kedua tepung tergolong kuat meskipun ukuran partikel tepung pupa sutra Eri yang berbeda tidak memberikan pengaruh nyata., Eri silkworm pupae (Samia cynthia ricini) have nutritional and antioxidant values that can be used as food products in the form of flour. As a food product, it is necessary to test its microbiological properties so that its feasibility is known. Microbiological properties were analyzed by calculating the Total Plate Count, E. coli, S. aureus and Salmonella sp. Meanwhile, the process of sifting flour with the aim of homogenizing the particle size will affect the antioxidant activity. Therefore, the antioxidant activity in Eri silk flour with particle sizes of 80 mesh and 60 mesh was tested through DPPH inhibition activity and antioxidant capacity. Data analysis used a completely randomized design (CRD) and independent T-test. The results showed that the value of the TPC, E. coli and Salmonella sp. has met the standard provisions of SNI 3751:2009. The number of S. aureus cells was <105 colonies/g which indicated that the amount of contamination did not exceed the thresholdhe analysis of the antioxidant activity was classified as strong although the different particle size did not have a significant effect.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
