Web conference feature embedded in Learning Management System (LMS) has been implemented in Sampoerna University (SU) to support mandatory Teaching-and-Learning from home activities during early stage of Covid-19 spreading period in Jakarta. The use of technologies and Internet connection to support these academic activities became very essential. The objec-tive of this research is to analyze internet speed and quota con-sumptions to meet the web conference requirements. Lecturers and students need sufficient Internet quota, stable Internet connection with proper speed, either using wired or wireless connection, in prepaid or postpaid subscriptions for smooth online learning. This research was an exploratory and quantitative research with surveys using non-probability with identified voluntary response sampling. The results showed that web conferences using BigBlueButton for audio-call, text-based chat, and rarely updated presenter shared-screen consumed only 3.11% of average students’ Internet connection speed, while the quota consumptions for 3 Credit Points Course session were 129.15 MB (Megabyte) per session, and for 4 Credit Points Course session were 140.2 MB per session. It was concluded that students are supposed to experience no or less delay during web conferences, and still have plenty of Internet bandwidth that can be utilized to support Study-from-Home activities.

Populasi Indonesia yang besar menjadi pasar pengguna Telepon Seluler yang besar pula, di mana sebagian besarnya terkoneksi dengan Internet.

Ragam aplikasi untuk dapat berkomunikasi, bersosialisasi, dan berinteraksi semakin membentuk masyarakat pengguna yang semakin bergantung dengan teknologi ini. Diperlukan cukup edukasi kepada masyarakat untuk menggunakan teknologi ini dengan bijaksana, khususnya pada area beretika di Internet, mengingat konten yang tersebar dan terserap melalui Internet juga semakin cepat.Kata Kunci: Netiket, Internet, Media Sosial, Pesan Instan, Pengabdian kepada Masyarakat

Sport is primarily a mental and physical activity focused on competition with oneself, others, or the elements of nature—the contribution of sport to the modern world's social development, the nation, and the state. As history has shown, technical advancements have never diminished sports and linked to civilization's advancement in human life. Walking and bicycling are increasingly promoted as active modes of transportation and boosting physical activity levels. The elevated breathing rates in traffic microenvironments have generated worries about increased exposure to ultrafine particles. Amateur half marathoners did detrimental significantly when the temperature, heat index, and ozone levels rise. The athlete or recreational sportsperson can earn environmental information through several channels and devices. There are applications and widgets now embedded or separated from the device operating systems. This research aimed to find appropriate environmental information from recreational sportspeople's understanding and awareness of the environment's effect on sports performance. Walking (77) and running (48) were the most sports activities picked by the respondents. Then 99 (73%) respondents used environmental data before exercising. Weather (118) was the respondents' choice, followed by the temperature (47) and the air quality (30) picked by the respondents. Most respondents (72%) get environmental information from their smartphones, and 27 (18%) get it from the website. Environmental factors may impact sports activity performance, and the respondents used environmental information before the sports activities began. This research will later support the sports information system web application.

Mobile phones and tablets installed with a soundmeter application can be used as an alternative for recording noise pollution to support Occupational Health and Safety (OHS). Mobile and tablet applications that have been calibrated with a soundmeter has the ability to record sound pressure which could be a solution for data recording. An external microphone can be attached to mobile phones and tablets to improve the quality of recorded data from sound sources. This research aims to analyze and determine the differences between the sound captured by internal and external microphones, and then compared them with results from a soundmeter device. This research was conducted using quantitative methods with primary data being analyzed descriptively. It was concluded from this research that there were significant increments in sound pressure using external microphones compared to internal microphones, with increment average using external microphone of 6.11 dBA on mobile phone, and 8.09 dbA on tablet.

Aplikasi pengukur tingkat suara kini tersedia pada perangkat seluler di sistem operasi iOS dan Android. Aplikasi seluler ini dapat mengukur tingkat suara dalam desible (db). Saat dibandingkan dengan perangkat pengukur tingkat suara digital, hasil dari aplikasi tingkat suara ditemukan berbeda setelah beberapa kali pengujian. Aplikasi seluler yang sama pada perangkat seluler berbeda juga ditemukan hasil yang berbeda pula. Perlu dilakukan kalibrasi antara aplikasi dengan perangkat pengukur suara digital guna menghasilkan nilai yang mendekati atau sama. Metode ini nanti akan digunakan untuk memiliki data tingkat suara yang standar yang berasal dari perangkat IoT untuk disimpan pada sebuah platform data. Kata kunci: Perangkat Pengukur Tingkat Suara Digital, Aplikasi Pengukur Tingkat Suara, Kalibrasi.
