Abstract

Penentuan tingkat energi dari potensial osilator anharmonik dapat diperoleh dengan berbagai metode pendekatan. Penelitian ini bertujuan untuk menentukan koreksi tingkat energi osilator anharmonik 1 dimensi menggunakan metode perturbasi hingga orde 2 dimana potensial gangguan dianggap berbentuk kuartik . Metode perhitungan orde 2 dilakukan menggunakan gambaran Heseinberg dengan mendefinisikan operator kreasi dan anihilasi untuk mendapatkan koreksi energi pada tingkat tersebut. Berdasarkan perhitungan yang dilakukan, potensial gangguan harus memiliki nilai pada rentang agar metode yang digunakan valid. Perbandingan hasil koreksi tingkat energi perturbasi orde 2 dengan metode numerik dan WKB menunjukkan bahwa semakin tinggi tingkat energi semakin besar persentase error, sehingga metode perturbasi hanya sesuai jika digunakan pada tingkat energi rendah.

Abstract

The KY-038 sensor module is designed using Arduino UNO and LabView to allow human pulses. The experiment was carried out by making a design consisting of the KY-038 sensor module, Arduino UNO and LabView on a computer. LabView software is used to display pulse wave patterns. Measurement of the pulse will involve human objects with variations 3 namely relax (sit), sit and after running in place. The experimental results show that the different activities affect the voltage released on a chart that has a rating of 3 - 3.5 V. The more activities that are carried out before retrieving the pulse data, the greater the voltage that is read on the LabView results graph. After running in place, the value of the voltage and pulse are 3.5 V and 97 beats per minute, respectively

Abstract

PDAM is a company engaged in the distribution of clean water for the community. Some Indonesian people have become PDAM water customers to meet their water needs for their daily activities. Water quality is an important issue because it is closely related to health. In this paper, the design of the water quality monitoring system in PDAM Banyumas based on IoT is carried out by reviewing the parameters of electrical conductivity (EC) and dissolved solids (TDS). The result of measurement data can be accessed via the Android App on smartphone. The application is designed using HTTP and MQTT protocols. HTTP protocol is used on the user interface to retrieve the last measurement data. Meanwhile, the MQTT protocol is used to update measurement data so that the data transmission process is faster. The system will send notification via telegram if the water quality is below quality standard. The measurement accuracy test is done by comparing the monitoring device with the certified measuring instrument on samples of bottled drinking water and PDAM water. The results show that the performance of the designed monitoring device was 97.31% and the quality of the PDAM Banyumas water is very stable and safe for consumption.

Abstract

One of the alternative ways to reduce the use of fossil fuels is the advancement of energy storage devices and energy conversion devices for renewable energy. The electrode is an essential part of its electrochemical performance in energy storage. The specific surface area of the electrode will affect the energy density, lifetime, charging, and discharging of the energy storage devices. Graphene has been widely used for energy storage, such as batteries and supercapacitors. Generally, graphene is synthesized from graphite as a carbon source which some researchers have reported. However, they are still fighting against simple synthesis methods, low-cost raw materials, eco-friendly co-product, and large-scale production. Therefore, advanced research is required to bring graphene from laboratory-scale projects to industry. One of the best solutions is biomass as a raw material to replace graphite in synthesizing graphene. In this review, some methods for synthesizing graphene from biomass will explain briefly, following with their strength and weakness.

Abstract

Managers of universities have a responsibility to ensure that parking is available for all stakeholders, particularly students. When there is not enough parking space for the quantity of vehicles arriving, issues occur. Consequently, the atmosphere was no longer favorable due to the pandemonium of vehicles that had taken over. This research's objective is to create a working prototype of an vehicles parking system that can control the flow of vehicles into the campus area. This system's controller is a Wemos D1 Mini, which may be used with the ESP 8266 module to connect to the internet, RFID card for students' identities for drivers of motor vehicles, servo motors to control gateways, infrared proximity sensors to count the number of vehicless entering and exiting the parking area, and Google Firebase for student lecture scheduling databases are all examples of technology used in parking area today. The test results reveal that the system can successfully verify the schedule saved in Firebase and read the student's identity contained on the RFID card. Only students with class schedules on that day are permitted access to the parking area.

Abstract

Water is one of the most important elements in household life. Most households use PDAM services to meet their daily water needs. The use of water used for households is monitored by officers manually. This method causes various problems, namely errors in the recording by officers, errors in the process of input results, and ineffectiveness. One solution to overcome these problems is to design a monitoring system for PDAM water usage in real time. The design is made using NodeMCU as a microcontroller, Water Flow Sensor, RTC DS3231, 20X4 LCD, MIT App Inventor, and Firebase which will be displayed via LCD and Android application. The results showed that the designed tool can display data in the form of time, the volume of water, and cost with sensor accuracy of 98, 40%. In addition to these data, this study also produces QoS values, namely 0% packet loss, and 0,09 s delay.

Abstract

Its use as a water storage location means that it is not uncommon for the water tank to overflow if the water level exceeds the maximum limit. One of the airtight ultrasonic sensors is the JSN-SR04T ultrasonic sensor for measuring water levels. However, this sensor has a weakness in the measurement reading that is less accurate. One way to improve the accuracy of this sensor's reading is to use the Linear Regression method. The purpose of this research is to test the accuracy of sensor measurement and the effect of linear regression implementation. The platform used in this research is Antares which is used for storing measurement data results. The results of the sensor measurement test show that the sensor is less accurate in measurement, after being implemented with the linear regression method the measurement results are approaching accurate but there is still a slight difference. The linear regression method is able to improve the accuracy of measurement data results better than before using linear regression.

Abstract

The research objective is to design an IoT-based rice field irrigation turbidity monitoring system, where later farmers can monitor water turbidity and control the Internet of Things (IoT) through Turbidity sensor processing and the ESP8266 module produced by Relay and cloud Blynk processing. The research flow starts from a literature search, the software design process compiles program scripts for each component that has been programmed through the Arduino IDE application, then creates Blynk which is used to monitor or monitoring the turbidity of irrigation water in real time. After designing the hardware and software, the next stage is system testing, if there are constraints and the results are not appropriate, then the hardware and software design is carried out again until the test is successful and the data results are appropriate, then proceed to the next stage of making the test data results. The research results of the Water Turbidity Monitoring System and Rice Irrigation Ditch Control Using Blynk have been successfully designed and functioning properly. The turbidity sensor works well with sensor readings that pass the range of 10 to 70. If the sensor value is less than 10, the water is detected as clean, but the value is more than 70, then the water is detected as cloudy or dirty. Findings Quality of service (QoS) research shows unsatisfactory or poor results in the delay, packet loss, and throughput components, which are caused by poor internet connectivity.

Abstract

Sistem irigasi di Indonesia masih menerapkan metode tradisional, yaitu metode buka tutup untuk saluran irigasi ke sawah masih dilakukan secara manual dengan tenaga manusia. Metode tersebut dinilai peneliti kurang efektif dan efisien, sehingga diperlukan sistem monitoring dalam saluran irigasi tersebut. Monitoring ketinggian air diperlukan untuk menjaga debit air agar tidak merusak sawah ataupun tanaman lain disekitarnya. Sistem monitoring dirancang menggunakan sensor ultrasonic dan NodeMCU sebagai media komunikasi data yang terhubung dengan jaringan WiFi. Sistem ini berbasis Internet of Things sehingga proses monitoring dapat dilakukan melalui aplikasi Blynk pada smartphone. Penerapan sistem ini diharapkan dapat membuat pekerjaan para petani menjadi lebih efektif dan efisien. Dari hasil perancangan dan pengujian prototipe, dapat ditarik kesimpulan bahwa sensor ultrasonic memiliki pengukuran jarak ke permukaan air yang presisi dengan alat pembanding yaitu penggaris. Fungsi aktuator dan Blynk membuktikan bahwa kontrol jarak jauh berjalan dengan baik dan responsif dalam membuka atau menutup pintu irigasi dan mematikan atau menyalakan pompa DC. Hasil pengujian QoS masing-masing parameter memperoleh rata-rata, untuk delay sebesar 1491 ms, untuk throughput sebesar 6,131 kbps, untuk packet loss sebesar 11,36%. Berdasarkan standarisasi TIPHON, hasil pengujian parameter delay dan throughput masuk dalam kategori Buruk. Sedangkan hasil pengujian parameter packet loss masuk dalam kategori Baik. Hal ini dikarenakan Blynk server butuh waktu untuk menanggapi paket yang dikirim maupun paket yang diterima.
