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: Physicochemical Characteristics of Eri  Silkworm Pupae Flour (Samia cynthia ricini) with Different Particle Sizes.
Abstrak: Pupa adalah hasil samping di pengolahan serat sutra. Penggunaan pupa yang kurang optimal dapat menyebabkan pencemaran lingkungan. Sebagai produk pangan, diperlukan uji analisis sifat fisikokimia sehingga diketahui nilai gizinya. Sifat fisikokimia dianalisis dengan uji pH, uji aw, warna, dan analisis proksimat. Adanya pengayakan tepung pupa dilakukan dengan tujuan menghomogenkan ukuran partikel. Analisis data yang digunakan adalah Uji T-Independen. Hasil menunjukkan bahwa pH, aw, kadar air, kadar lemak, protein ukuran partikel 80 mesh tepung pupa lebih baik dari ukuran partikel 60 mesh. Akan tetapi, kadar abu, serat kasar, dan karbohidrat pada tepung 60 mesh lebih baik dari ukuran partikel 80 mesh. Ukuran partikel tidak memengaruhi karakteristik fisikokimia tepung pupa., Pupa is a byproduct in the processing of silk fiber. Suboptimal use of pupa can lead to environmental pollution. As a food product, it is necessary to conduct a physical-chemical analysis to determine its nutritional value. Physical-chemical properties are analyzed through pH testing, water activity (aw) testing, color analysis, and proximate analysis. Sieving of pupa flour is carried out with the aim of homogenizing particle size. The data analysis used is the Independent T-Test. The results show that pH, aw, moisture content, fat content, and protein content of 80 mesh pupa flour are better than that of 60 mesh particle size. However, ash content, crude fiber, and carbohydrates in 60 mesh flour are better than that of 80 mesh particle size. Particle size does not affect the physical-chemical characteristics of pupa flour.

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.
