Judul: Factor That Influence Impulse Buying in Generation Z (Shopee E-commerce Users)
Abstrak: Teknologi internet semakin berkembang pesat di seluruh dunia termasuk Indonesia. Dengan bertambahnya jumlah penduduk maka jumlah pengguna internet juga ikut meningkat. Saat ini masyarakat memiliki tren untuk melakukan belanja online akibat dari pesatnya perkembangan e-commerce di Indonesia. Konsumen yang melakukan pembelian produk yang dilakukan secara online sebagian besar mengalami impulse buying atau pembelian yang tidak direncanakan. Tujuan penelitian ini yaitu untuk menganalisis karakteristik konsumen dan faktor apa saja yang memengaruhi terjadinya impulse buying pada generasi Z pengguna e-commerce Shopee. Penelitian ini menggunakan data primer dan data sekunder. Data primer berasal dari kuisioner yang diisi oleh responden yang merupakan generasi Z pengguna e-commerce Shopee. Metode yang digunakan yaitu metode analisis deskriptif dan analisis model persamaan struktural dengan pendekatan partial least square (SEM-PLS). Hasil penelitian menunjukkan faktor emotion, hedonic shopping, dan time available memiliki pengaruh positif dan signifikan terhadap perilaku impulse buying generasi Z dengan faktor dominan yaitu faktor hedonic shopping yang memiliki nilai t statistik sebesar 3,629., Internet technology is overgrowing throughout the world, including in Indonesia. The number of internet users has also increased with the increase in population. Currently, people have a trend to do online shopping due to the rapid development of e-commerce in Indonesia. Consumers who make product purchases made online mainly experience impulse buying or unplanned purchases. The purpose of this study is to analyze the characteristics of consumers and what factors influence the occurrence of impulse buying in Generation Z of Shopee e-commerce users. This study uses primary data and secondary data. Primary data comes from questionnaires filled out by respondents who are Generation Z users of Shopee e-commerce. The method used is the descriptive analysis method and structural equation model analysis with a partial least squares approach (SEM-PLS). The results showed that emotion, hedonic shopping, and time available factors had a positive and significant influence on the impulse buying behaviour of Generation Z. The dominant factor was the hedonic shopping factor, which had a t-statistical value of 3,629.

Judul: Mitochondrial DNA Gene Organization and Phylogenetic Relationship of Naja siamensis
Abstrak: Naja siamensis is one of Asiatic cobra in the Family of Elapidae, known as a cryptic snake. It has many morphological variations that lead to misidentification. Misidentification can cause the wrong concept in developing antivenom types due to high snakebite cases occur in Thailand. Thus, an accurate species identification using a molecular approach is crucially required. Mitochondrial DNA has been used widely in snake molecular studies. These studies were aimed to determine the arrangement of the N. siamensis partial mitochondrial genes using reptile-oriented primers and to reveal the phylogenetic relationship among other species of Asian cobra. DNA extraction was carried out based on the standard DNA salting-out protocol and was conducted by bioinformatics analysis using BLASTn and MEGA 6 software. Gene annotation was performed against N. kaouthia complete genome. A total of 3121 bp of N. siamensis mtDNA genes were sequenced consisting of partial of six regions: 16S rRNA, ND1, tRNA-Ile, CRII region, tRNA-Leu, tRNA-Gln, and COI genes. The mtDNA gene organization of N. siamensis was predicted to has a similar pattern with the common Elapidae mtDNA gene organization. This study showed that there is a monophyletic form in Naja genus and N. kaouthia is the closest species with N. siamensis based on partial 16S rRNA and ND1 gene.
