The Research and Development Center for The Soil and Agricultural Land Resources Office estimates that Indonesia's peatland area is around 14.9 million H. In the dry season, peatlands experience dryness, so they burn easily. More than 99% of the causes of forest and peatland fires are human-made, either deliberately burning or neglecting to use fire. IoT (Internet of Things) technology is used to connect all devices to the internet and enable communication of each other, one reason for which is that digital data stored on cloud storage, then display the data on a website. The website was designed to monitor the peat's condition by considering the peat's air temperature, peat soil temperature, peat soil moisture, and humidity around the peatlands. IoT retrieves and sends data to the cloud, then websites retrieve and display data from the cloud in diagram and table format for easy reading of monitors. Website monitoring systems utilize several components, including domains as addresses, web hosting as web data storage, and the CMS framework CodeIgniter is used as the basis of the application. Sending data from IoT to web hosting requires cloud storage. Without this, it is necessary to transfer data from the IoT to the website manually. The monitor system can read temperature and humidity sensor data, store it in the cloud, then display it on a website so that the data monitoring process runs well.

− Sunlight data intensity is critical for Indonesia, which is positioned on the equator's line. This project develops a real-time sunshine intensity observation system using the Internet of Things (IoT), allowing data to be easily accessed from any location. This utility was created using a microcontroller NodeMCU and an LDR module calibrated with a Luxmeter Lx-103. Data is transmitted via the Message Queuing Telemetry Transport protocol, which provides a protocol Quality of Service 1. The trial lasted 12 hours outside. Obtaining research data that linear regression LDR: y = (-128.14*VADC)+18,621.42 and R2= 0.9693 with maximum sunlight intensity counted at 21,451.9 Lux at 9 AM and an average range of light intensity between 13659.26 and 20964.86 Lux in the middle of the day. NodeMCU processed the LDR data and then displayed it on the LCD with a one-second delay. Data was provided to the mqtt server at a 60second frequency, and the most recent steps were recorded in the SQLite database.

ABSTRACT− Forest and land fires are a very serious issue in Indonesia, especially in KSP Rawa Batang Banyu which has the potential to experience sustainable development. Hotspots created by NASA-FIRMS (National Aeronautics and Space Administration - Fire Information for Resource Management System) can indicate forest and land fires. The purpose of this study is to analyze the number and density of hotspots with the correlation between hotspots and rainfall with ONI and rainfall in the last 10 years (2009-2018). This study uses Spatial analysis, Time Series Analysis, Pearson Correlation analysis, with hotspot, rainfall, and ONI data that have been released. As a result, the hotspot density conditions in each region were concentrated in Cintapuri Darussalam, Banjar Regency and Binuang, Tapin Regency. Real-Time Analysis shows the highest number of hotspots in the 2009-2018 period reached its highest point in September. Pearson correlation analysis between hotspot and rainfall data shows a value of -0.224 which indicates that the relationship is very weak and inversely proportional. The correlation between ONI data and rainfall shows a value of -0.066 which indicates that the relationship is weaker than the previous correlation and also inversely proportional.

−Vanadium Redox Flow Battery (VRFB) is a relative new type of secondary battery that has ability as Energy Storage System (ESS) for renewable energy power plants such as solar cell. 2D VRFB single cell was modeled using COMSOL Multiphysics software and simulated numerically by using Nernst-Planck, secondary current distribution, tertiary current distribution and Buttler-Volmer principle. Simulation was conducted at 293,15 K, with electrode thickness variations of 1 mm (L1), 2 mm (L2), 3 mm (L3), 4 mm (L4) and 5 mm (L5). According to the simulation results, it is known that electrolyte potential in negative electrode is higher than positive electrode and the distribution is tend to decrease for all variations. Surface concentration near collector is dominant during charging compare inlet position and the reverse phenomenon occur during discharging process. VRFB L1 show weak performance and VRFB L2 show the best performance in term of electrolyte potential and species molarity in the electrode surface.

A wireless data logger system measuring indoor acoustic quality was developed using a NodeMCU ESP8266 and microphone sensor KY-037. The acoustic quality is based on parameters of sound pressure level and reverberation time. The system consists of a transmitter unit and a receiver unit. The transmitter unit is equipped with a Microphone KY-037 sensor as a sound detector and NodeMCU ESP8266 as a microcontroller and serial communication with the database. The transmitter unit of this measuring instrument is set at predetermined position points in a room. The results of testing the sound pressure level have an error percentage of 2.09% compared to the Digital Sound Level Meter GM1356 tool. Comprehensive testing of the tool has sent and processed sensor measurement data wirelessly into the database. The processed data is displayed through a GUI web server in the form of a background noise average, an average of the reverberation time value, and a graph of the sound pressure level in the room.

The plasterboard ceiling is one of the applications of fiber-based composite materials. Asbestos fibers, usually used to make plasterboard ceilings, are unfortunately harmful to humans. We propose using banana midrib fibers that are environment-friendly to replace asbestos fibers. This research investigates the influence of the percentage of banana midrib fibers on the fill weight, water absorption, and density of plasterboard ceilings. The fibers extracted from banana midrib were immersed in 40 mL of 1 M NaOH and then used to prepare plasterboard ceiling samples with different fiber percentages, namely 0.0%; 1.0%; 1.5%; 2% 2.5%. The fill weight, water absorption, and density of plasterboard samples were measured and then compared to Indonesian National Standard. The highest fill weight of 1.52 g/cm3 was obtained with a 1.0% percentage of banana midrib fibers for the plasterboard sample. In contrast, the highest water absorption of 11.84% was obtained at 2.5% banana midrib fibers. The more fibers added, the better the seepage of the plasterboard ceilings.Â
