Judul: The Influence of Hedonic Shopping Motivation and Discount Toward Impulse Buying in JABODETABEK Area.
Abstrak: Perkembangan internet menyebabkan masyarakat memilih berbelanja secara online karena kemudahan-kemudahan yang diberikan. Perilaku pembelian masyarakat juga mulai berubah dari pembelian terencana menjadi pembelian yang tidak terencana atau dikenal sebagai pembelian impulsif. Pebisnis online perlu bersaing untuk meningkatkan penjualan yang salah satunya melalui perilaku pembelian impulsif. Tujuan dari penelitian ini adalah untuk mengidentifikasi karakteristik konsumen, mengidentifikasi perilaku belanja online, menganalisis tanggapan konsumen terhadap hedonic shopping motivation dan potongan harga, dan menganalisis pengaruh hedonic shopping motivation dan potongan harga terhadap pembelian impulsif pada belanja online. Metode analisis yang digunakan adalah analisis deskriptif dan analisis regresi linier berganda. Variabel bebas dalam penelitian ini adalah hedonic shopping motivation dan potongan harga. Hasil uji F menunjukkan bahwa hedonic shopping motivation dan potongan harga berpengaruh secara simultan terhadap pembelian impulsif. Hasil uji t menunjukkan bahwa hedonic shopping motivation (sig. 0.000) dan potongan harga (sig. 0.011) memiliki pengaruh yang positif dan signifikan terhadap pembelian impulsif pada belanja online.

Judul: Analysis of the Effect of Utilitarian and  Hedonic Attributes on Impulse Buying with Cognitive and Affective Attitude
Abstrak: Pengguna internet di Indonesia tahun demi tahun mengalami peningkatan dari tahun ke tahun. Perkembangan tersebut membuat masyarakat menggunakan paylater menjadi salah satu jenis fintech technology yang sering digunakan oleh masyarakat. Saat konsumen berbelanja online, terdapat tiga jenis atribut, diantaranya, atribut utilitas, dan atribut hedonis. Atribut utilitas ini dapat memengaruhi perilaku konsumen yang merujuk pada cognitive attitude dan atribut hedonis ini berhubungan dengan persepsi konsumen mengenai utilitas dan fungsi dari sebuah objek yang merujuk pada sikap afektif. Cognitive dan affective attitude ini memiliki hubungan timbal balik yang dapat memungkinkan perilaku pembelian impulsif. Oleh karena itu, peneliti ingin menganalisis pengaruh utilitarian dan hedonic attributes terhadap perilaku impulse buying pada pengguna paylater di jabodetabek dengan pendekatan cognitive dan affective attitude. Penelitian ini menggunakan sampel sebanyak 235 responden pengguna paylater di Jabodetabek. Sampel penelitian ditentukan menggunakan metode non-probability sampling. Selanjutnya, hasil penelitian dianalisis menggunakan analisis deskriptif dan Structural Equation Modeling-Partial Least Squares (SEM-PLS)., Internet users in Indonesia are increasing year by year. This development makes people use paylater as one type of fintech technology that is often used by the public. When consumers shop online, there are three types of attributes, including utility attributes and hedonic attributes. These utility attributes can influence consumer behaviour which refers to cognitive attitude and these hedonic attributes relate to consumer perceptions of the utility and function of an object which refers to affective attitude. This cognitive and affective attitude has a reciprocal relationship that can enable impulsive buying behaviour. Therefore, researchers want to analyse the effect of utilitarian and hedonic attributes on impulse buying behaviour in paylater users in Jabodetabek with a cognitive and affective attitude approach. This study used a sample of 235 paylater user respondents in Jabodetabek. The research sample was determined using non probability sampling method. Furthermore, the research results were analysed using descriptive analysis and Structural Equation Modeling-Partial Least Squares (SEM-PLS).

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
