A wind direction sensor has been implemented for many applications, such as navigation, weather, and air pollution monitoring. In an odor tracking system, the wind plays the important role to carry gas from its source. Therefore, the precise, low-cost, and effective wind direction sensor is required to trace the gas source. In this study, a new design of wind direction sensor has been developed using thermal anemometer principle with the main component of the positive temperature coefficient thermistor. Three anemometers each of which has different directions are used as inputs for the neural network to determine the direction of the wind automatically.The experimental results show that the wind sensor system is able to detect twelve wind directions. A mobile robot equipped with this sensor system can navigate to a wind source in the open air with a success rate of 80%.This system is expected to increase the success rate of the mobile robot in searching for dangerous leaking gas in the open air.
Penggunaan sistem informasi dan teknologi yang cepat dirasa cukup penting dalam membantu proses belajar mengajar. Oleh sebab itu, diusulkan penggunaan platform E-Learning untuk membantu guru. Fitur yang diajarkan diarahkan untuk dapat melakukan pemberian materi, tugas, ujian, kuisioner, dan organisasi kegiatan. Para pengajar dilatih mengimplementasikan aplikasi online, seperti google drive, google form, untuk mendukung kegiatan bahan ajar, dengan sasaran guru guru SMA Tuban, Jawa Timur, Indonesia. Peserta merasa terbantu dengan sistem ini dan berencana mengaplikasikan kedalam proses pengajaran. Dari hasil training, para peserta merasa antusias terhadap pelatihan ini, dimana mereka mampu membuat, dan mempraktekkan fitur fitur yang ada di Google untuk membantu pekerjaan mereka. Dari hasil kuisioner tingkat kepuasan, sebanyak 15 dari 17 orang peserta pelatihan merasa terbantu dengan adanya pelatihan ini. Kemudian sebanyak 14 orang peserta juga merasa hasil pelatihan Information and Communication Technology yang diikuti relevan dengan permasalahan dan dapat dijadikan alternatif solusi yang membantu guru dalam proses kegiatan belajar. Peningkatan pemahaman juga dialami oleh peserta workshop sebelum dan setelah bergabung dengan kegiatan sosialisasi. dalam proses pembelajaran, merujuk pada data tingkat pemahaman yang diambil sebelum dan setelah pelatihan.
This study and analysis was carried out to examine the effect of emotional marketing on purchase intention. This study also analyzes the mediating role of brand awareness and brand trust in the relationship between emotional marketing and purchase intention. This study uses a questionnaire as an instrument of study and has collected valid and reliable data from 130 respondents who are users of MSME products who are actively promoting on Instagram social media. This study adopted the Structural Equation Model (SEM) with the Partial Least Square (PLS) technique to test the hypothesis in this study. This study proves that brand awareness and brand trust have a mediating role in the relationship between emotional marketing and purchase intention. This means that emotional marketing has an indirect effect on purchase intention through brand trust and brand awareness. This study also proves that emotional marketing does not have a significant impact on purchase intention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
