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: Antioxidant, Organoleptic, and Microbiological Activities of Eri Silkworm (Samia cynthia ricini) Pupae Flakes Product
Abstrak: Ulat sutra Eri (Samia cynthia ricini) merupakan ternak yang menghasilkan produk sampingan berupa pupa. Pupa dapat dimanfaatkan sebagai bahan substitusi tepung polenta pada pembuatan produk pupae flakes. Penelitian ini bertujuan untuk menganalisis cemaran mikrobiologi (total plate count, Escherichia coli, dan Staphylococcus aureus), aktivitas dan kapasitas antioksidan, serta organoleptik pada produk flakes ulat sutera eri. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan tepung polenta dengan tepung pupa pada tiga taraf berbeda yaitu 0%, 4%, dan 8%. Hasil analisis mikrobiologi pada pengujian total plate count dan bakteri Escherichia coli memenuhi standar SNI, namun pengujian bakteri Staphylococcus aureus tidak memenuhi standar SNI. Pengujian antioksidan pupae flakes menunjukkan peningkatan aktivitas dan kapasitas antioksidan. Hasil pengujian organoleptik pupae flakes memberikan pengaruh nyata terhadap semua atribut pada uji hedonik dan mutu hedonik., Eri silkworm (Samia cynthia ricini) is a livestock that produces by-product of pupae. Pupae can be used as a substitute for polenta flour to manufacture pupa flakes. This study aims to analyze microbiological contaminants (total plate count, Escherichia coli, and Staphylococcus aureus), antioxidant activity and capacity, and organoleptic in silkworm flakes products. This study used a completely randomized design (CRD) with polenta flour and pupa flour at three levels, namely 0%, 4%, and 8%. The results of microbiological analysis on total plate count testing and Escherichia coli bacteria met the SNI standards, but the Staphylococcus aureus bacteria test did not meet the SNI standards. Antioxidant testing of pupae flakes showed an increase in antioxidant activity and capacity. The organoleptic testing results of pupae flakes significantly affected all attributes in the hedonic test and hedonic quality.

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.
