Banjir memiliki dampak negatif yang cukup banyak salah satunya adalah rusaknya sarana dan prasarana masyarakat. Kesiagaan masyarakat cukup penting diperlukan untuk mengurangi dampak negatif dari banjir tersebut. Salah satu solusi yang dapat dilakukan adalah dengan merancang suatu sistem simulasi peringatan dini banjir sebagai alat dalam mendetaksi ketinggian air sebelum terjadi datangnya bahaya banjir. Penelitian ini bertujuan untuk membuat prototipe sistem peringatan dini bencana banjir yang mudah dioperasikan dan efektif untuk mendeteksi datangnya banjir. Pada protipe terdapat sensor level switch yang mampu mendeteksi pergerakan tinggi permukaan air pada daerah aliran sungai. Data hasil pengukuran tersebut akan diolah menggunakan PLC Omron sebagai pusat pengolahan data. Hasil olah data selanjutnya dikirim ke Arduino Uno untuk mengirim pesan kepada pengguna menggunakan modul GSM SIM800L V.2. Jika permukaan air mencapai ketinggian yang telah ditentukan, maka alarm buzzer berbunyi dan lampu LED menyala. Hasil pengujian menunjukkan bahwa respon sensor banjir dengan alarm peringatan sangat cepat yaitu kurang dari 3 detik. Waktu pesan SMS hingga sampai pada ponsel penerima relatif cepat yaitu dibawah 15 detik. Kata Kunci: Arduino uno, banjir, GSM SIM 800L, PLC Omron, sensor level switch, sistem peringatan diniAbstract Flooding is a problem that occurs as a result of excess water volume in the river which is influenced by human activities that are not friendly to the environment. Floods have quite a number of negative impacts, one of which is the destruction of community facilities and infrastructure. Community preparedness is important enough to reduce the negative impact of the flood. One solution that can be done is to design a flood early warning simulation system as a tool in detecting water levels before flood danger occurs. This study aims to make a prototype of a flood early warning system that is easy to operate and effective for detecting floods. In the prototype there is a level switch sensor that is able to detect movement of water level in the watershed. The measurement data will be processed using Omron PLC as a data processing center. The results of data processing are then sent to Arduino Uno to send messages to users using the GSM SIM800L V.2 module. If the water level reaches a predetermined height, the buzzer alarm sounds and the LED lights up. The test results show that the response of flood sensors with a very fast warning alarm is less than 3 seconds. The time of the SMS message to arrive at the recipient's cellphone is relatively fast, namely under 15 seconds.
In the current era, people will compete to share their travel experiences to get feedback from their friends or colleagues. This story is an Electronic word of mouth (E-WOM) that can have a positive or negative impact on the company. E-WOM is any statement both positive and negative made by potential, actual, or past consumers about a product or company made to a large number of people or institutions via the internet (Hennig-Thurau, 2004 in Prasad, et al, 2017) . This is also used by The Great Asia Africa Lembang, one of the tourist destinations in West Bandung Regency that uses social media as a medium to promote the uniqueness of existing attractions. This study examines the effect of Electronic Word Of Mouth (E-WOM) on the decision to visit The Great Asia Africa Lembang, West Bandung Regency. The method used in the research in this journal uses quantitative methods that are analyzed by alternative partial least squares (PLS) with a sample of 270 respondents. The findings in this study indicate the influence of Electronic Word Of mouth (E-Wom) on the decision to visit tourists. The limitation in this study is only using a sample of Instagram followers from The Great Asia Africa, so it is necessary to expand the reach of the population to get more diverse responses. From the results of the research obtained, it shows that Ewom's assessment is still in the good category so that it can be improved to be very good by increasing the productivity of the content created and conducting periodic research to find out the effectiveness of the influence of Electronic Word of Mouth.
Purpose: In the growth of family companies, corporate entrepreneurship is very important for the sustainability of family companies that are managed across generations. Sustainability of family companies is more successful in implementing corporate entrepreneurship than other companies. Therefore, researchers study the influence of families on corporate entrepreneurship. This study examines why some families are better at encouraging corporate entrepreneurship in their companies than others. Design/methodology/approach: The method used in this study uses a qualitative method using a study library. A search was conducted on the Scopus database of 33 articles in publications 2005-2021 published in scientific journals included in the inclusion criteria. Findings: The results of this Systematic Mapping study can provide an overview of opportunities to explore new topics on mapping corporate entrepreneurship in family businesses. The most discussed topics are HR, strategy and organizational culture in the general industry and manufacturing sectors. Research limitations/implications: This research is limited to using only one Scopus database. Practical implications: The implications of the research from a practical point of view are how this research data can be better managed in the future by researchers and professionals engaged in entrepreneurship and family businesses. Originality/value: This paper provides a clear description of the role of corporate entrepreneurship in family businesses. This brings together and maps for the first time in an integrated manner several topics related to corporate entrepreneurship in family businesses. This leads to the conclusion that topics related to corporate entrepreneurship in successful family businesses refer to the relationship between human resource management and organizational culture Paper type: Literature review
Purpose: The megashifting industry encourages tourism to be able to survive in the face of crises and create a new balance with new management systems and activities. One of the new changes, namely Accelerated Digitalization or the acceleration of digitization and the pandemic, has encouraged consumers to switch to the digital/online realm. This is also used by The Great Asia Africa Lembang, one of the tourist destinations in West Bandung Regency that uses social media marketing as a medium to promote the uniqueness of existing attractions. This study examines the influence of Social Media Marketing (SMM) on the decision to visit The Great Asia Africa Lembang, West Bandung Regency. Design/methodology/approach: The method used in the research in this journal uses quantitative methods that are analyzed by alternative partial least squares (PLS) with a sample of 270 respondents. Findings: The findings in this study indicate that the performance of social media marketing in The Great Asia Africa Lembang, West Bandung Regency is categorized as strong with each QMS dimension that forms the construct significantly. Based on the four dimensions that make up, content creation is the dominant dimension, this shows that the content created by The Great Asia Africa can be accepted by the public as a source of tourism information. Research limitations/implications: The limitation in this study is that it only uses a sample of Instagram followers from The Great Asia Africa, so it is necessary to expand the reach of the population to get a more diverse response.
