Abstract

Monitoring the availability of parking lots in the campus area is very important. This is related to the solution of the problem of limited parking spaces for four-wheeled vehicles. Existing parking spaces can be optimized by adding a vehicle detection device. This vehicle detection device uses ultrasonic sensors and its programming is based on the ESP32 Microcontroller. Sensitivity parameters measured are object detection distance, influence of other frequencies, influence of passing objects and range areas horizontally and vertically. In the research, the measurement results obtained are object detection distance up to 350 cm, the influence of other frequencies does not exist, passing objects can be detected by vehicle detection devices, range areas vertically up to 250 cm and horizontally up to 150 cm. Based on the test results, the distance reading by the ultrasonic sensor on the vehicle detection device is accurate. This measurement is in accordance with the specifications of the GH-311 type ultrasonic sensor used in the device.

Abstract

Geometri merupakan salah satu pelajaran pada matematika yang melibatkan benda baik berupa bangun datar maupun bangun ruang. Hal ini membutuhkan kemampuan visualisasi yang baik oleh siswa. Kemampuan visualisasi ini dapat dirangsang dengan menggunakan alat-alat peraga baik yang konvensional maupun menggunakan teknologi. Tanpa adanya alat peraga yang memadai maka siswa akan mengalami kesulitan dalam memahami pelajaran Geometri. SDS Muhammadiyah 6 sebagai mitra dalam pengabdian ini memerlukan penggunaan alat peraga maupun teknologi dalam proses pembelajaran Geometri. Dengan demikian fokus dalam pengabdian ini adalah memberikan alat peraga dan pelatihan salah satu teknologi berupa software Geogebra. Geogebra dapat digunakan untuk menampilkan bangun datar maupun bangun ruang yang lebih interaktif sehingga mengembangkan visualisasi siswa. Penggunaan software ini juga sejalan dengan kurikulum merdeka belajar yang menekankan akan penggunaan teknologi dalam proses pembelajaran. Pengabdian ini dimulai dengan memberikan pembelajaran dengan menggunakan alat peraga dan dilanjutkan dengan pengenalan software Geogebra untuk siswa tingkat SD. Hasil dari pengabdian ini memberikan pengalaman yang baru dan meningkatkan minat siswa terhadap matematika khususnya pembelajaran Geometri dan penggunaan IPTEK

Abstract

The issue of environmental damage due to the expansion of palm oil plantations in Indonesia has become a global issue. It has often hampered the development of the downstream palm oil industries in Indonesia. The European market was once closed to palm oil and derivative products from Indonesia. In fact, this industry has become a source of income and employment for millions of Indonesians. Therefore, palm oil industry must be supported with sustainable efforts. One of them is developing SADS (Soil and Air Detector System) model. Which is a tool for detecting soil and air environmental conditions around palm oil plantations. The parameters are soil PH, CO2 levels, temperature and humidity, and sunlight. The measurement results from this tool can be accessed and displayed in real-time via the internet. This is research aims to build a smart system as a solution to environmental problems around palm oil plantations. This is useful for knowing and observing the condition of palm oil plantations and as a basis for taking mitigation actions if the condition is in a critical state

Abstract

Control and monitoring systems in poultry farm cages are very necessary, especially for broiler farmers because the harvest process from growth to ready to harvest takes 30 to 35 days with a weight per tail between 1.5-2.0 kg. Important variables that are prioritized in broiler cages, namely temperature, humidity and lighting as well as the availability of feed and drinks on time, determine the quality and quantity of the broiler harvest. The solution to these problems requires a system that can work automatically with real-time monitoring features so that important variables in the chicken coop can be really well maintained. This research uses a combination of DHT11 temperature and humidity sensors, proximity sensors as sensors to check the availability of water and feed in containers, LDR light sensors and GY-302 Lux sensors, Real Time Clock timer modules to organize scheduling the availability of drinking water and chicken feed. These sensors will provide data to the ESP32 controller to control outputs such as heating and cooling and valves for opening and closing the stock of drinking water and feed. This system has also been integrated with the Internet of Things so that the condition of the chicken coop can be flexibly monitored remotely using a Smartphone or laptop utilizing the internet network. Based on the tests that have been carried out, it proves that the system has worked well in maintaining important variables in the chicken coop and has been well integrated based on the Internet of Things.

Abstract

The researcher wants to make a KWH meter monitoring tool with estimated usage costs so that the tools he makes can help the community to minimize costs in the electricity consumption area, especially in the workshop room located on the 1st floor of building C at Medan State Polytechnic. The long-term goal of this research is to develop an Internet of Things (IoT)--based KWH meter monitoring tool that can read current, voltage, frequency, power factor, and power consumption. This utilization shows the use of costs that have been incurred in real-time by displaying the results on the LCD and can also be from the user's mobile phone. In this study, the strategy used in the energy management framework was determined using SWOT analysis. From the results of the measurement and monitoring of electrical energy consumption obtained the results that, energy management is carried out by applying Standard Operating Procedures for the use of electrical energy in the electrical engineering workshop room in order to save more minimal energy consumption with a large error (Error) PZEM in measuring Voltage is 0.0198% in measuring Current is 0.612%. in measuring Cosphi is 0.01%. in measuring Frequency is 0.003%. in measuring Power is 0.183%. And the average measurement error rate is below 0.5%, namely 0.23%.

Abstract

In order for the designed tool to simulate solar panel measurements based on real-world conditions, the solar panel placement holder was arranged in a specific way during the design process. A monitor display that is mounted on the design will show the effectiveness of the solar panels and provide general solar panel information. Limitations in the positioning of solar panels will not provide a reference to conditions for measurement depending on the angle of incidence of the sun so further design needs to be done regarding the position of solar panels when measurements are taken. The development carried out in the design of this tool is in the form of adjusting the solar panel holder in the form of a solar panel holder tilt of 0°, 90°, 180°, and a distance of 30 cm halogen lamp as an energy source that is measured. Measurement results based on design, temperature 46°C, and 100% light.

Abstract

Researchers want to make a kWh meter monitoring tool with estimated usage costs so that the tools made can help people to minimize costs in electricity usage. The purpose of this research is the creation of an IoT-based kWh meter monitoring tool that has the ability to read current, voltage, frequency, power factor and power usage that flows and shows the use of costs that have been used in real time with the display results on the LCD and also on the user's smartphone. In the reading results of usage costs (Rp) on the tool and PLN there is also a difference of Rp. 12,000, where the reading results on the tool are also lower than the results of the payment slip provided by PLN. The cost reading error rate on the tool is 4.4% with a reading accuracy rate of 95.6%.
