Judul: Effectiveness of Direct Message Interactions in Increasing Bens Aqiqah Sales through Meta Business Suite Ads Results
Abstrak: Hasil iklan tidak terlepas dari adanya interaksi. Interaksi mempengaruhi peningkatan penjualan hasil iklan. Bens Aqiqah merupakan bisnis yang menerapkan iklan sebagai upaya peningkatan penjualannya, tetapi interaksi pada platform iklannya yaitu Meta Business Suite belum berjalan optimal. Tujuan penelitian ini untuk mengetahui interaksi, membandingkan efektivitas interaksi dan merekomendasi strategi interaksi dalam mengoptimalkan hasil iklan. Penelitian ini menggunakan metode in-depth interview dan observasi dalam pengumpulan data serta analisis deskriptif, uji t independen dan 3E Social Media Strategy Canvas dalam menganalisis data. Hasil penelitian yang dilakukan menunjukkan bahwa perlakuan interaksi kedua (balasan chatbot dengan follow up dan follow up dengan balasan dilanjutkan) lebih efektif dibandingkan perlakuan interaksi pertama (balasan chatbot tanpa follow up dan follow up tanpa balasan dilanjutkan). Dibuktikan 20 closing pada perlakuan kedua dan tidak ada closing pada perlakuan pertama dari hasil iklan Meta Business Suite Ads melalui direct message. Rekomendasi sebagai upaya peningkatan penjualan interaksi pada Bens Aqiqah diberikan dengan menerapkan pelayanan interaksi yang berkelanjutan dan optimal. Kata kunci: facebook, instagram, interaksi, meta business suite, perlakuan, Advertising results cannot be separated from interaction. Interaction influences increased advertising sales. Bens Aqiqah is a business that uses advertising as an effort to increase its sales, but the interaction on its advertising platform, namely Meta Business Suite, is not running optimally. The aim of this research is to determine interactions, compare the effectiveness of interactions and recommend interaction strategies in optimizing advertising results. This research uses in-depth interviews and observation methods in collecting data as well as descriptive analysis, independent t test and 3E Social Media Strategy Canvas in analyzing data. The results of the research conducted showed that the second interaction treatment (chatbot reply with follow up and follow up with continued reply) was more effective than the first interaction treatment (chatbot reply without follow up and follow up without continued reply). It was proven that there were 20 closings in the second treatment and no closings in the first treatment from the Meta Business Suite Ads advertising results via direct messages. Recommendations as an effort to increase interaction sales at Bens Aqiqah are given by implementing sustainable and optimal interaction services.

Judul: Performance Comparison between Facebook Ads and Instagram Ads to Find Best Marketing Channel: Case Study RasaKoe
Abstrak: Engagement media sosial mempengaruhi penjualan pada bisnis. Pada tahun 2022, salah satu bisnis bernama RasaKoe tidak mencapai target penjualan. Dengan target pasar yang tersebar di Facebook dan Instagram serta sumber daya yang terbatas, RasaKoe perlu mengetahui saluran pemasaran terbaik untuk meningkatkan engagement yang dapat dioptimalkan dengan penggunaan yang lebih sering. Tujuan penelitian ini adalah untuk menganalisis perbandingan performa iklan RasaKoe di platform Facebook dengan Instagram, menentukan saluran pemasaran digital RasaKoe yang paling efektif dan efisien, dan memberikan rekomendasi untuk meningkatkan engagement media sosial RasaKoe. Penelitian ini menggunakan metode in-depth interview dan observasi dalam mengumpulkan data dan menggunakan analisis deskriptif, uji t independen, dan 3E Social Media Strategy Canvas dalam menganalisis data. Hasil penelitian ini menunjukkan bahwa Instagram lebih efektif dalam memperoleh engagement rate daripada Facebook, Social media engagement influences business sales. In the year 2022, one business named RasaKoe did not achieve its sales target. With a target market spread across Facebook and Instagram and limited resources, RasaKoe needs to determine the best marketing channels to enhance engagement, which can be optimized through more frequent use. The objective of this research is to analyze the performance comparison of RasaKoe's advertisements on the Facebook and Instagram platforms, determine the most effective and efficient digital marketing channels for RasaKoe, and provide recommendations to improve RasaKoe's social media engagement. This study utilizes in-depth interviews and observations for data collection and employs descriptive analysis, independent t-test, and the 3E Social Media Strategy Canvas for data analysis. The research findings indicate that Instagram is more effective in achieving an engagement rate compared to Facebook

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.
