Judul: Analysis of factors influencing consumers’ behavior towards buying decision of frestea (study case of students of bachelor degree of bogor agricultural university)
Abstrak: Tujuan dari penelitian ini adalah untuk mengidentifikasi karakteristik konsumen yang melakukan pembelian Frestea, untuk mengidentifikasi proses pengambilan keputusan pembelian konsumen Frestea, menganalisis faktor-faktor yang mempengaruhi pengambilan keputusan konsumen dalam pembelian Frestea dan menganalisis sikap konsumen terhadap atribut-atribut yang dimiliki oleh Frestea. Metode yang digunakan dalam penelitian ini adalah uji validitas, uji reliabilitas, analisis deskriptif, analisis multiatribut Fishbein dan analisis faktor. Karakteristik konsumen yang digunakan dalam penelitian ini terdiri dari jenis kelamin, usia, daerah asal, tempat tinggal, pengeluaran per bulan dan sumber dana. Berdasarkan analisis multiatribut Fishbein, nilai sikap konsumen terhadap Frestea sangat baik dengan skor sebesar 211.81. Berdasarkan hasil analisis faktor terdapat tiga faktor yang terbentuk seperti faktor pengaruh lingkungan sekitar dan sosial, faktor psikologis, dan faktor perbedaan individu., The purpose of this research were to identify the consumer characteristics that purchase Frestea, to identify consumer buying decision process of Frestea, to analyze the factors that influence consumer decision making in purchasing Frestea and to analyze consumers’ attitude towards Frestea’s attributes. The methods used in this research were validity test, reliability test, descriptive analysis, multiatribute Fishbein analysis and factor analysis. Consumer characteristics used in this study consist of gender, age, region of origin, place of residence, spending per month and source of fund. Based on the multiatribute Fishbein analysis, the value of consumer attitudes toward Frestea is excellent with a score of 211.81. Based on factor analysis, three factors were formed such as factor that influences the surrounding environment and social, psychological factor and factor of individual differences.

Judul: Gene Editing  of Two Cyanide Synthesis-related Genes in Cassava using CRISPR/Cas9
Abstrak: Cassava (Manihot esculenta) contain toxic quantities of cyanogenic glucoside. Reducing the potentially toxic cyanogenic glucoside levels in cassava could be achieved by gene editing through Clustered Regularly Interspaced Short Palindromic Repeats – CRISPR associated protein 9 (CRISPR/Cas9), a high- precision genome editing technique in plants. Two cassava UDP- glucosyltransferase (UGT) paralogs, UGT85K4 and UGT85K5, are the genes catalyzing the synthesis of cyanogenic glucosides in plants. The study aimed to construct the CRISPR/Cas9 recombinant vector carrying single guide RNA (sgRNA) to edit UGT85K4 and UGT85K5 genes, and transform sgRNA CRISPR/Cas9 construct into KU50 cassava calli. Five sgRNAs were designed, considering the on/off target efficiency score and GC content. Those sgRNAs were ligated into pRGEB32 plasmid and introduced to competent Escherichia coli DH5a. The PCR colony and DNA sequencing were performed to verify the sgRNA insert. The amplicons showed the expected band size of recombinant vector (180 bp). Based on sequencing results, only one sgRNA was successfully ligated into the plasmid that will be used to edit the UGT85K5 gene. The sgRNA CRISPR/Cas9 construct in pRGEB32 plasmid was successfully transformed into Agrobacterium tumefaciens and introduced into KU50 cassava calli through co-cultivation. The overgrowth of Agrobacterium occurred after the co-cultivation phase.
