Abstract

Community service is part of the Tri Dharma of Higher Education which must be implemented. As an aspect of their mandatory duties, all campus academics have an obligation to carry out community service. Community service can be carried out using various methods, models, strategies and service topics. One of these topics is strengthening or deepening basic physics material using teaching aids and based on the application of technology that is widely used. This activity was carried out with the aim of providing reinforcement of basic physics material for students at MAN 1 Selong, East Lombok Regency. This service is also aimed at introducing the use of microcontrollers as learning tools. The service is divided into three sub-stages, namely an introduction to material on quantities in physics, providing examples of cases of analysis of physical quantities, and simple training on operational methods for microcontrollers as data processing elements and temperature sensors. This stage is carried out using the Arduino IDE application. This activity provides benefits for students in increasing direct understanding regarding the temperature quantity which is a basic quantity, the unit conversion process, and the application of digital technology in measurement activities. Students are trained to apply Arduino IDE devices, Arduino UNO microcontrollers, and create basic programming with Arduino IDE. Students can also more easily measure temperature and other quantities using tools designed independently and display the results on the screen. Students are able to carry out temperature unit conversions manually and also through programming. The application of a microcontroller can make it easier for students to carry out data analysis. The results of this service can improve students' understanding of basic physics material. Students are able to use microcontrollers and design teaching aids.

Abstract

Pertumbuhan populasi dan aktivitas ekonomi yang pesat di Lombok Timur telah meningkatkan ancaman pencemaran udara yang berdampak buruk pada kesehatan manusia, hewan, dan tumbuhan. Sebagai upaya untuk mengatasi hal ini, program peningkatan kapasitas dan kesadaran lingkungan telah dilaksanakan di SMAN 2 Selong, Lombok Timur. Program ini bertujuan untuk meningkatkan pengetahuan siswa tentang pencemaran udara serta cara-cara untuk meminimalisir dampaknya. Melalui metode Direct Instruction, Focus Group Discussion (FGD), dan demonstrasi alat ukur (PM10), siswa diberikan pemahaman teoritis dan praktis mengenai pencemaran udara. Hasil kegiatan ini menunjukkan peningkatan pengetahuan dan kesadaran siswa terkait pentingnya menjaga kualitas udara dan melakukan tindakan preventif terhadap polusi udara. Diharapkan, melalui kegiatan ini, siswa dapat berperan aktif dalam menjaga kelestarian lingkungan di sekitar mereka

Abstract

QCM or quartz crystal microbalance is a non static crystal that can be used as a mass sensor. As a piezoelectric crystal, a QCM generates an electrical signal with a specific frequency. The frequency change can be utilized as a frequency counter in a mass measurement system. This study aims to develop a coarse particle sensor system using a QCM and an oscillator circuit. In line with this, this study uses an oscillator circuit and a QCM for a sensor development. Thus, the frequency measurement of the QCM contains an oscillator and a signal conditioner connected to a microcontroller. For this purpose, an Arduino Nano was used as the signal processing, while a QCM was used as a coarse particle sensor and compared to a digital dust sensor (Winsen ZH03). The sensor system was evaluated using a fixed-type crystal connected to an oscillator: 2.5 MHz - 7.2 MHz. Arduino Nano processed the frequency signal generated by the developed oscillator. The results show that the sensor system has a stable output signal compared to the comparator. There is a linear correlation between the frequency measured by the system and the oscilloscope (99.73%). It can be concluded that the sensor system can measure coarse particle concentrations from 32-620 ug/cm3 (frequencies from 2 MHz to 7.2 MHz) with a response time of 1 second. The system has an accuracy of 99% and a resolution of 1 Hz.

Abstract

AbstrakSaat ini, promosi media untuk meningkatkan kesadaran masyarakat akan pola hidup sehat menjadi tantangan tersendiri di pemerintah daerah, seperti Dinas Kesehatan (Dinkes) di Provinsi Susa Tenggara Barat. Organisasi ini masih menerapkan ukuran konvensional dalam melakukan program promosi, seperti Radio, Surat Kabar, Flyer, dan lain-lain. Hal ini belum bisa menjangkau seluruh responden, terutama generasi muda yang seharusnya mengakses media sosial. Tujuan dilakukannya konten podcast adalah untuk memperluas jangkauan responden remaja melalui penerbitan video edukasi kesehatan di YouTube. Adapun metode yang digunakan dalam pelaksanaan pengabdian yaitu pendekatan participatory rural appraisal, serta pendekatan persuasive dan edukatif. Kegiatan dibagi dalam 3 tahapan penting yaitu persiapan, pembuatan konten, dan evaluasi. Hasil kegiatan pengabdian menunjukkan bahwa pembuatan konten youtube edukasi Kesehatan melalui podcast telah berhasil dilakukan dan dapat diakses pada https://www.youtube.com/@dinaskesehatanprovinsintb3184/videos. Berdasarkan hasil diskusi, program diberi nama SENIN SEHAT sesuai arahan pemerintah provinsi NTB kepada seluruh Organisasi Perangkat Daerah (OPD) terkait. Program telah menghasilkan Sembilan episode diantaranya hubungan komunikasi dan kesehtan, pemberian makanan pendamping air susu ibu, waspada kasus demam berdarah, dll. Oleh karena itu, podcast ini menjadi salah satu inovasi untuk melakukan edukasi secara efektif dan interaktif kepada masyarakat. Kata kunci: media informasi; senin sehat; teknologi informasi; teknologi komunikasi Abstract Recently, the media promotion to enhance citizens' awareness of healthy lifestyles has become a challenge in the local government, such as the West Susa Tenggara Province health department. The organization still applies conventional measurements to promote programs such as radio, newspapers, and flyers. The previous approach could only reach some respondents, especially young people who are supposed to access social media. The aim of establishing podcast content is to expand the reach of teenage respondents through publishing health education videos on YouTube. The methods used in implementing the service are the participatory rural appraisal approach and the persuasive and educational approach. Activities are divided into three critical stages: preparation, content creation, and evaluation. The results showed that creating health education YouTube content through podcasts was successfully carried out and can be accessed at https://www.youtube.com/@dinaskesehatanprovinsintb3184/videos. Based on the discussion, the program was named SENIN SEHAT according to the direction of the NTB provincial government. The program has produced nine episodes, including communication and health relations, providing complementary foods with breast milk, alerting for dengue fever cases, etc. Therefore, this podcast is an innovation that offers effective and interactive education to the public. Keywords: information media; healthy monday; information technology; communication technology.

Abstract

A QCM (Quartz Crystal Microbalance) can be developed as a humidity sensor with a selective coating material. TiO2 (titanium dioxide) is a metal oxide with several crystal phases: anatase and rutile phases. However, there are few studies on the crystal phase investigation of a TiO2-based humidity sensor. Thus, this study aimed to develop a humidity sensor by functionalizing TiO2 particles with different crystal phases. The coating materials were prepared by ultrasonication. The synthesis was conducted by mixing 7 mL of TTIP (Titanium (IV) Isopropoxide) precursor in ethanol. This solution was stirred for 30 minutes, ultrasonicated, and heated for 16 hours to make a gel. The next step was a calcination process with two different temperatures to produce different crystal phases: 500oC (anatase) and 700oC (rutile). The synthesized powders were analyzed using XRD-SEM and coated onto the surfaces of the QCMs used as the developed sensors. These sensors were tested inside a chamber using a humidity control kit and a frequency counter (humidity levels: 57% to 92%). The results show that the rutile phase has a smaller particle diameter (252.672 nm) than the anatase phase (384.589 nm). The humidity sensing examinations indicate that the anatase-phase sensor has faster response-recovery times (19 seconds and 8 seconds) than the rutile-phase sensor (28 seconds and 50 seconds). It can be concluded that TiO2 particles in the anatase and rutile phases can be functionalized as a high-sensitivity coating material for a QCM humidity sensor.
