Judul: Keanekaragaman simplisia nabati dan produk obat tradisional di Kota Pematangsiantar dan Kabupaten Simalungun, Sumatera Utara
Abstrak: The utilization of medical plants as traditional medicine is a great inherintance which has been used until present. Medicinal plants used in the form of vegetable simplisia and traditional medicine products. This study aims to identified the form an diversity of vegetable simplisia and traditional medicine product, traditional medicine products traded, the selling price and origin of the traded vegetable simplisia supply and the potential for sustainable management of medicinal plants as vegetable simplisia. Data and information are collected in Pematangsiantar and Simalungun, North Sumatera using direct observation and interviews with purposive sampling. The results show that 113 species of medicinal plants come from 46 families that dominated by Zingiberaceae. Vegetable simplisia dominated by herb life form and simplisia leaf (folium) are organ of the most used medicinal plants as medicine by local communities and the traders medicinal plants. The majority of medicinal plants traded and local communities utilized are cultivated plants which selling price around Rp 16 000-Rp 700 000 each kilogram. There were included 22 spesies medicinal plants of threatened category according to IUCN, CITES LIPI, and Permen LHK No. P.106 Year 2018.

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.
