Judul: Analisis pengaruh persepsi promosi dan persepsi harga terhadap keputusan pembelian dan brand switching FreshCare Aromatherapy
Abstrak: Sejak lama masyarakat Indonesia mengenal produk minyak angin. Aroma dan kehangatannya dipercaya dapat meredakan berbagai penyakit ringan seperti flu, sakit kepala, mual, untuk penghangat tubuh, meredakan perut kembung, mabuk perjalanan, dan sebagai pelemas otot. Industri farmasi merupakan pasar global yang dinamis sehingga perlu respon yang cepat dan inovasi yang kreatif untuk perkembangan pasar. Penelitian ini bertujuan untuk menganalisis pengaruh persepsi promosi dan persepsi harga terhadap keputusan pembelian dan brand switching FreshCare Aromatherapy. Alat analisis yang digunakan dalam penelitian ini adalah tabulasi silang dan analisis regresi dengan jumlah sampel sebanyak 100 responden. Hasil tabulasi silang antara kepuasan dan loyalitas konsumen adalah adanya korelasi antara keduanya. Dengan menggunakan analisis regresi, dapat diketahui bahwa persepsi promosi tidak berpengaruh positif terhadap keputusan pembelian pada konsumen, sedangkan persepsi harga berpengaruh positif terhadap keputusan pembelian. Dari hasil kuesioner telah diketahui pula bahwa sebagian besar konsumen puas dan tidak akan berpindah merek.

Judul: Analisis Pengaruh Persepsi Promosi dan Persepsi Harga Terhadap Keputusan Pembelian dan Brand Switching FreshCare Aromatherapy
Abstrak: Indonesian society has long known the wind oil products. Fragrance and warmth believed to relieve a variety of ailments such as colds, headaches, nausea, to body warmers, relieve flatulence, motion sickness, and as muscle relaxants. The pharmaceutical industry is a dynamic global market that need a quick response and creative innovations to market developments. This study aimed to analyze the influence of perception and perception promotional price on purchasing decisions and brand switching FreshCare Aromatherapy. Analysis tools used in this study is cross-tabulations and regression analysis with a sample size of 100 respondents. Results of cross-tabulation between satisfaction and customer loyalty is a correlation between the two. By using regression analysis, it can be seen that the perception of promotion is not a positive influence on consumer purchasing decisions, while a positive influence price perception on purchase decisions. From the results of the questionnaire have also known that the majority of consumers are satisfied and will not switch brands.

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.
