Judul: Analisis Viral Marketing dan Reference Group Terhadap Purchase Intention (Green Concept Kopi Nako Daur Baur)
Abstrak: Indonesia menjadi negara penghasil sampah plastik di laut terbesar kelima di dunia, sehingga pemerintah mengeluarkan aturan tentang peta jalan pengurangan sampah. Di sisi lain, indeks lingkungan hidup di Indonesia meningkat, sehingga Kopi Nako melakukan viral marketing dengan bertanggung jawab terhadap sampah plastik mereka menjadi desain arsitektur dalam bangunan usahanya. Penelitian ini bertujuan untuk menganalisis viral marketing dan reference group terhadap purchase intention (green concept Kopi Nako Daur Baur). Penelitian ini menggunakan metode SEM-PLS kepada 275 responden yang merupakan orang yang mengetahui tentang Kopi Nako Daur Baur. Hasil penelitian menunjukkan bahwa viral marketing dan reference group berpengaruh signifikan terhadap brand awareness dan purchase inetntion, selain itu brand awareness juga memiliki pengaruh yang signifikan terhadap purchase intention. Penelitian ini memberikan implikasi bagi pemilik usaha Kopi Nako Daur Baur agar terus berinovasi sehingga bisa menjangkau pasar yang lebih luas, memberikan reward potongan harga kepada konsumen, membuat kartu anggota, dan mengadakan event dengan lebih baik lagi.

Judul: Analysis of Perceptions Analysis and Factors Affecting the Implementation of Green Consumption Behavior in Little Talk Coffee Shop Consumers
Abstrak: Meningkatnya model bisnis indsutri pangan di Indonesia yang perlu didisrupsi dengan menghadirkan inovasi yang lebih ramah lingkungan seperti substitusi bahan kemasan yang tidak ramah lingkungan. Konsumen bijak sebelum melakukan pembelian suatu produk akan memikirkan terlebih dahulu dampak dari produk yang dikonsumsinya. Penelitian ini bertujuan untuk mengdentifikasi persepsi konsumen (generasi Z) terhadap produk hijau yang disajikan di kedai kopi Little Talk dan menganalisis pengaruh pengetahuan lingkungan, sikap lingkungan dan produk hijau terhadap penerapan perilaku konsumsi hijau ketika mengunjungi kedai kopi Little Talk. Metode analisis data yang digunakan dalam penelitian ini adalah analisis deskriptif kuantitatif dengan skala likert dan Structural Equation Modeling - Partial Least Square (SEM-PLS) dengan bantuan software SmartPLS4. Hasil penelitian menunjukkan konsumen (generasi Z) setuju dengan produk hijau yang disajikan oleh kedai kopi Little Talk. Berdasarkan hasil pengujian hipotesis sikap lingkungan berpengaruh signifikan terhadap produk hijau dan perilaku konsumsi hijau, sedangkan pengetahuan lingkungan tidak berpengaruh signifikan terhadap sikap lingkungan, produk hijau, dan perilaku konsumsi hijau. Dengan demikian perlu peningkatan pengetahuan konsumen (generasi Z) terhadap lingkungan untuk mendorong peningkatan perilaku konsumsi hijau., The increasing business model of the food industry in Indonesia needs to be disrupted by presenting more environmentally friendly innovations such as substituting packaging materials that are not environmentally friendly. Wise consumers before purchasing a product will first think about the impact of the products they consume. This study aims to identify consumer perceptions (generation Z) of green products served at Little Talk coffee shops and analyze the influence of environmental knowledge, environmental attitudes and green products on the application of green consumption behavior when visiting Little Talk coffee shops. The data analysis method used in this research is quantitative descriptive analysis with a Likert scale and Structural Equation Modeling - Partial Least Square (SEM-PLS) with the help of SmartPLS4 software. The results showed that consumers (generation Z) agree with the green products served by Little Talk coffee shops. Based on the results of hypothesis testing, environmental attitudes have a significant effect on green products and green consumption behavior, while environmental knowledge has no significant effect on environmental attitudes, green products, and green consumption behavior. Thus, it is necessary to increase consumer (generation Z) knowledge of the environment to encourage increased green consumption behavior.

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
