The Covid-19 pandemic that occurred in Indonesia led to the implementation of online or online learning in educational institutions so that the teaching and learning process can be carried out. In practice, online learning in universities has positive and negative impacts, especially in the health sector. The purpose of the study was to determine the effect of online learning on stress and zoom fatigue as well as the characteristics that affect D III nursing students at Sari Mutiara University, Indonesia. This research is a correlation analytic study with a cross sectional design. The sampling technique used purposive sampling with the number of respondents as many as 44 people. Data collection was carried out by distributing questionnaires through Google Forms which were sent to students by researchers via whatsapp. The bivariate test used to determine the relationship between online learning and the characteristics that affect stress and zoom fatigue is the Spearman correlation test. The results showed that there was a relationship between online learning and stress levels (p value = 0.009 ; r = 0.389). There is no relationship between age (p value = 0.327 ; r = -0.151); gender (p value = 0.851, r = 0.029); internet connection (p value = 0.276 ; r = -0.098); duration of online learning (p value = 0.369; r = -0.139) with the stress level of nursing students. There is a relationship between online learning (p value = 0.049; r = 0.299, age (p value = 0.018; r = 0.355), duration of online learning (p value = 0.037; r = 0.316) with zoom fatigue in nursing students. There is no relationship between gender (p value = 0.527, r = 0.098), internet connection (p value = 0.929; r = 0.014) and zoom fatigue in nursing students. Lecturers need to innovate/modify learning media with various applications that do not require high concentration, so that fatigue and stress on students do not occur.   Abstrak Pandemi Covid-19 yang terjadi di Indonesia menyebabkan diterapkannya pembelajaran daring atau online diinstitusi pendidikan supaya proses belajar mengajar dapat dilaksanakan. Dalam pelaksanaannya pembelajaran daring di perguruan tinggi memiliki dampak positif dan negatif terutama dibidang kesehatan. Tujuan penelitian adalah untuk mengetahui pengaruh pembelajaran online terhadap stres dan zoom fatigue serta karakteristik yang mempengaruhi pada mahasiswa D-III keperawatan Universitas Sari Mutiara Indonesia. Penelitian ini merupakan penelitian analitik korelasi dengan rancangan cross sectional. Teknik pengambilan sampel menggunakan purposive sampling dengan jumlah responden sebanyak 44 orang. Pengumpulan data dilakukan dengan penyebaran angket melalui Google Form yang dikirim kepada mahasiswa oleh peneliti melalui whatsapp. Uji bivariat yang digunakan untuk mengetahui hubungan pembelajaran online dan karakteristik yang mempengaruhi stres dan zoom fatigue adalah uji korelasi Spearman. Hasil penelitian menunjukkan ada hubungan antara pembelajaran daring dengan tingkat stres (p value = 0,009 ; r = 0,389). Tidak ada hubungan antara usia (p value = 0,327 ; r = -0,151); jenis kelamin (p value = 0,851, r = 0,029); koneksi internet (p value = 0,276 ; r = -0,098); durasi belajar daring (p value = 0,369; r = -0,139) dengan tingkat stres mahasiswa keperawatan. Ada hubungan antara pembelajaran daring (p value = 0,049 ; r = 0,299,  usia (p value = 0,018 ; r = 0,355),  durasi belajar daring (p value = 0,037; r = 0,316) dengan zoom fatigue pada mahasiswa keperawatan. Tidak ada hubungan antara jenis kelamin (p value = 0,527, r = 0,098), koneksi internet (p value = 0,929 ; r = 0,014) dengan zoom fatigue pada mahasiswa keperawatan. Dosen perlu melakukan inovasi/modifikasi media pembelajaran dengan berbagai aplikasi yang tidak memerlukan konsentrasi yang tinggi, sehingga kelelahan dan stress pada mahasiswa tidak terjadi.

Escherichia coli bacteria found in refilled drinking water shows that the quality of the drinking water does not meet the requirements of drinking water refill depots (DAMIU) set by the government, both in terms of bacteriological examination and human resources. It is probably caused by poor equipment maintenance as well as irregular sanitation and hygiene measure by the owner. According to Permenkes No 492/Menkes/PER/IV/2010, one of the requirements of drinking water is said to be consumable if the total content of Escherichia coli bacteria is 0 per 100 ml. The purpose of this study was to analyze the relationship between equipment maintenance and monitoring of drinking water refill depots with Escherichia Coli contamination in drinking water refill depots in Dolok Masihul District, Serdang Bedagai Regency. This study was an analytical type of research with a cross-sectional design. The population in this study was all DAMIU in Dolok Masihul District, Serdang Bedagai Regency, amounted to 15 DAMIU. By employing a total sampling technique, a total number of 15 DAMIU served as research samples. Based on the results of the Fisher Exact test, it was found that there was a relationship between equipment maintenance and Escherichia coli contamination (p-value = 0.007), and there was a relationship between processing supervision and Escherichia coli contamination in drinking water refill depots in Dolok Masihul District, Serdang Bedagai Regency (p-value = 0.017). It is recommended to the DAMIU manager to complete sanitation facilities and equipment such as closed trash cans, SPAL with a fluent and closed flow, replace gallon brush bristles every 3 months, and carry out regular drinking water quality checks and report to the local Health Office.

Covid-19 merupakan penyakit sistemik yang klinisnya sangat bervariasi mulai dari gejala ringan hingga penyakit berat kritis dengan risiko mortalitas tinggi. Perubahan kadar trombosit, limfosit, neutrofil, ferritin, D-dimer dan fibrinogen dapat memprediksi risiko perburukan pasien Covid-19. Tujuan penelitian untuk mengetahui pengaruh parameter biomarker terhadap outcome pasien Covid-19. Penelitian ini menggunakan data sekunder dari rekam medis yang dirawat inap di RSUP H. Adam Malik Medan periode Januari 2020 hingga Desember 2020. Pengambilan sampel menggunakan teknik Non Probability Sampling yaitu Purposive Sampling sebanyak 129 orang. Instrumen penelitian yang digunakan adalah lembar observasi trombosit, limfosit, neutrofil, D-dimer, ferritin dan fibrinogen. Uji yang digunakan untuk mengetahui hubungan parameter biomarker laboratorium terhadap outcome pasien Covid-19 adalah uji korelasi Spearman. Hasil penelitian menunjukkan tidak ada hubungan antara trombosit (p value = 0,607 ; r = -0,046) dan ferritin (p value = 0,093 ; r = 0,149) dengan outcome pasien. Ada hubungan antara limfosit ( p value = 0,029; r = 0,192), neutrofil (p value = 0,001; r = 0,292), D-dimer (p value = 0,008 ; r  = 0,264) dengan outcome pasien Covid 19.
