Abstract

Liquefied Petroleum Gas (LPG) is a flammable gas. Leaks in LPG gas cylinders that are not known to the user can have a fatal impact if there is no system that detects and stop the leak. Therefore, this study designed a system to detect and solve LPG gas leaks based on the Internet of Things automatically. The way this system works is that the MQ-6 sensor detects the concentration of LPG gas around the cylinder with an analog value limit when the safe condition is <400 and the danger condition is 400. The sensor will continue to detect as long as the tool is on and send data to the microcontroller in the form of NodeMCU ESP8266 which then transmits the data to Firebase. From Firebase, users will get information about LPG gas levels in safe/dangerous conditions, gas position control, as well as fan and buzzer conditions through a smartphone application in real time. If the conditions are safe, the green LED will light up and the condition is dangerous, the microcontroller will physically respond to the servo motor to turn the regulator valve open, the fan, the red LED and the buzzer while virtually the user will get information through the application and notifications via the WhatsApp application in the form of a short message as a warning that gas was detected. The test results show that the LPG gas detection system can work well.

Abstract

Sleeps disorders are a common disease overlooked by many people. Sleep disorder have many types and kinds and often associated with other severe illness such as diabetes, stroke, obesity and many others. Sleep monitors are one of many ways to read all parameters related to sleep and detect sleep disorders the subject has, however access to sleep monitor still expensive and tough to come by. Because of that accessibility, countless development of home sleep monitor occured around the world. However, most of that device still hard to operate and some of them gives error readings of parameters. Based on this, a portable low-cost home sleep monitor was developed using Wemos D1 mini as a microcontroller, MAX30102 as an oxygen level sensor, MPU6050 as an accelerometer, DS18B20 as a breathing flow sensor, and MAX9814 as a microphone. Each of the sensors read and give value to microcontroller and store the data to cloud and display the result in user’s gadget. The aim of this development is to detect sleep disorders associated with each reading of sensors used and determine sleep quality as an early detection of symptoms before referring to professional relaled to sleep disorders or doctors.

Abstract

Pemantauan volume urin  merupakan parameter penting dalam penanganan pasien di Intensive Care Unit (ICU). Namun, proses pengukuran yang masih dilakukan secara manual berisiko menimbulkan kesalahan pencatatan dan meningkatkan beban kerja tenaga medis. Penelitian ini mengembangkan sistem timbangan kantong urin portabel berbasis Internet of Things (IoT) menggunakan sensor load cell HX711 dan mikrokontroler Wemos D1 Mini untuk pemantauan volume urin secara otomatis dan real-time. Data pengukuran dikirim melalui WiFi ke server lokal dan divisualisasikan pada nurse station berbasis web. Hasil pengujian menggunakan analisa regresi linear sebanyak 600 sampel menunjukkan akurasi sistem sebesar 99,7% dengan galat maksimum ±3 mL serta konsistensi pembacaan di atas 99%. Analisis statistik juga menunjukkan variasi pengukuran maksimum sebesar ±1,55 mL pada interval kepercayaan 97,5%. Sistem yang dikembangkan mampu melakukan pemantauan volume urin secara presisi dan andal sehingga berpotensi meningkatkan efisiensi pemantauan pasien di lingkungan ICU.

Abstract

As a tourism village, Ponggang faces problems related to waste management that are currently not being handled properly. If not followed up, this will pose a threat to both public health and the potential for damage to the village's natural and environmental attractions. Therefore, this community service aims to empower community groups through the utilization of plastic waste into products with higher economic value (eco-conblock). The methods used in this service include outreach activities aimed at increasing awareness and understanding of partners about the concept of village tourism and training/mentoring activities that involve the active role of community members aimed at increasing technical skills and waste management governance. From the evaluation results, it can be seen that the aspect of community awareness and understanding of good waste management has significantly increased from 3.85 points (good) to 4.47 points (very good). Meanwhile, the aspect of skills and governance has increased significantly on average from 3.39 points (moderate) to 3.68 points (good). In addition, the community service program has also succeeded in building an integrated waste management facility that can later be used sustainably towards Ponggang becoming an independent tourism village.
