Judul: Karakteristik Fisik dan Kimia serta Uji Toksisitas Tepung Pupa Ulat Sutera (Samia cynthia) Pemakan Pemakan Pemakan Pemakan Daun Jarak (Ricinus communis).
Abstrak: Pupa ulat sutera merupakan salah satu edible insects yang dapat dimanfaatkan sebagai bahan pangan alternatif di masa mendatang. Tujuan dari penelitian ini adalah untuk mempelajari karakteristik fisik dan kimia serta uji toksisitas tepung pupa Samia cynthia. Penelitian ini dilaksanakan pada bulan Februari hingga Juni 2017. Tahapan dalam penelitian ini meliputi tahap pembuatan tepung pupa Samia cynthia, analisis karakteristik kimia tepung pupa Samia cynthia pada tiga suhu pengeringan, analisis karakteristik fisik tepung pupa Samia cynthia terpilih, dan uji toksisitas tepung pupa Samia cynthia terpilih dengan metode BSLT (Brine Shrimp Lethality Test).

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.
