Prototype of CO, CO2 , UV Light, Temperature and Humidity Detection Device Based on IoT and Solar Cells
Get PDFExposure to air pollution, excessive ultraviolet (UV) light, and changes in environmental temperature and humidity can have serious impacts on human health. Therefore, a tool design was created that combines Solar Cell-based technology and the Internet of Things (IoT) to detect potential dangers from air pollution, exposure to UV rays, and changes in environmental temperature and humidity. This tool uses an ESP32 microcontroller as its brain, which allows data to be collected from the sensors used. The sensors used include the MQ2 Sensor for toxic gas detection, the MQ135 Sensor for CO2 pollutant gas detection, the UV Sensor for monitoring harmful UV radiation, and the DHT11 Sensor for measuring environmental temperature and humidity. The information collected by these sensors is displayed in real-time via an OLED display, giving users an instant understanding of the level of danger that may exist in their surroundings. Apart from that, this tool uses Solar Cells as a power source, so it can operate independently and is environmentally friendly. This tool has great potential for use in a variety of environments, including residential areas, work spaces and open areas. It helps society as a whole to maintain their health and safety by providing accurate and real-time information about the dangers that may be around them. KEYWORDS: DHT-11, ESP-32, GUVA S12SD, Internet of Things (IoT), MQ-2, MQ-135 Solar Cell
PREDIKSI DEBIT ANDALAN DAS CILOSEH MENGGUNAKAN FJ MOCK DAN BANGKITAN DATA DEBIT THOMAS FIERING UNTUK ANALISA KETERSEDIAAN AIR DEARAH IRIGASI CIMULU
Get PDFKetersediaan air menjadi isu krusial di Indonesia, terutama di wilayah dua musim. Residu dari aktivitas manusia mengancam ketersediaan air sungai, serta diperparah oleh perubahan iklim global yang berdampak pada suhu, curah hujan, dan debit sungai. Fokus penelitian adalah DAS Ciloseh, sumber air utama untuk DI Cimulu. Metode FJ Mock digunakan untuk memodelkan debit andalan (80%) DAS, melibatkan metode Penman Modifikasi, Polygon Thiessen, dan Thomas Fiering. Hasil analisis menunjukkan bahwa tutupan lahan, khususnya sawah, memengaruhi debit andalan. Luas DAS, jenis tanah, dan tutupan lahan menjadi parameter penting. Debit andalan DAS Ciloseh berkisar 5,30 m3/s hingga 14,70 m3/s untuk 100 tahun ke depan. Pembangkitan data menggunakan metode Weibull menunjukkan fluktuasi debit mengikuti pola historis. Penelitian ini memberikan kontribusi penting untuk memahami ketersediaan air di DAS Ciloseh, yang memiliki implikasi besar untuk pengelolaan sumber daya air di masa depan

Scrutinising the Contribution of Textual and Visual Resources in Campaign Posters: An SF-MDA
Get PDFThis qualitative research aims to analyse the textual and visual resources used in four campaign posters to promote parents’ awareness of children’s language development and reveal the contributions of each semiotic resource in representing the messages in the selected posters. The research data were four campaign posters promoting parents’ awareness of children’s language development published by Worcestershire Speech & Language Therapy NHS Trust for the “We Need to Talk” Month campaign. The data was obtained from Worcestershire Speech & Language Therapy’s official Twitter account, @SLT_Worcs. The research design used in this research was Multimodal Content Analysis (Serafini & Reid, 2019). This research employed document analysis and purposive sampling techniques to collect the data. Then, the data were analysed using SF-MDA analytical tools: Halliday and Matthiessen’s ideational meaning of Systemic Functional Linguistics (2004) and Kress and van Leeuwen’s representational meaning of Visual Grammar (2006). The findings showed that the textual resources mostly have material processes, indicating that the NHS Trust is trying to invite the viewers to take action and work together to overcome the issue and raise the viewers’ awareness. Meanwhile, all of the visual resources have transactional reaction processes, which indicate that the NHS Trust is addressing the viewers directly (using a gaze) to respond and react to the represented participants’ (depicted in the posters) gaze to work together to overcome the issue being raised in the four selected campaign posters.
