AbstrakUsaha budidaya ikan kerapu mempunyai prospek yang cukup baik untuk dikembangkan. Perkembangan produksi ikan kerapu cantang (Epinephelus sp.) menunjukkan kinerja yang cukup baik dengan peningkatan produksi rata-rata dari tahun 2010-2014 sebesar 9,61%. Kendala yang sering dihadapi pada kegiatan budidaya ikan kerapu adalah terjadinya serangan bakteri, salah satunya bakteri patogen. Serangan bakteri patogen menimbulkan penurunan kualitas dan tingkat produksi pada usaha pembenihan maupun pendederan ikan kerapu, bahkan kematian serta kegagalan panen dapat terjadi. Penelitian ini dilaksanakan pada bulan Mei-Juni 2016. Penelitian dilakukan di laboratorium Kesehatan dan Lingkungan BPBAP Situbondo dan di Laboratorium Bakteri Balai Karantina Ikan Kelas I Juanda, Surabaya. Tujuan dari penelitian ini adalah untuk mengetahui jenis bakteri pada benih ikan kerapu cantang di kolam pendederan BPBAP Situbondo. Metode yang digunakan dalam penelitian ini adalah metode observasi. Observasi yaitu melakukan pengamatan secara langsung ke objek penelitian untuk melihat dari dekat kegiatan yang dilakukan. Data yang diperoleh dari penelitian isolasi dan identifikasi bakteri pada benih ikan kerapu cantang dianalisis secara deskriptif dan disajikan dalam bentuk gambar dan tabel. Hasil dari penelitian ini menunjukkan adanya bakteri pada benih ikan kerapu cantang dari kolam pendederan Balai Perikanan Budidaya Air Payau (BPBAP) Situbondo, Jawa Timur yaitu bakteri Vibrio alginolitycus, Vibrio harveyi dan Streptococcus iniae. Faktor terbesar yang mempengaruhi tertularnya bakteri pada benih ikan kerapu cantang antara lain adanya agen patogen dari pakan ikan rucah yang kualitasnya kurang bagus serta sifat kanibalisme ikan yang menyebabkan luka di permukaan tubuh ikan sehingga bakteri mudah masuk ke tubuh ikan dan menimbulkan infeksi.Kata Kunci: Isolasi, Identifikasi, Bakteri, Benih, Epinephelus sp. AbstractThe cultivation of grouper have good prospects for development. Production development cantang grouper (Epinephelus sp.) showed a good performance with an increase in average production from 2010-2014 amounted to 9.61%. often mistake encountered on grouper aquaculture is the attack bacteria, one of which pathogenic bacteria. The attack pathogenic bacteria cause a decrease in the quality and level of production at the hatchery and nursery businesses grouper, as well as crop failure and even death can occur. This study was conducted in May-June 2016. The study was conducted in the laboratory of Health and Environment BPBAP Situbondo and in laboratory bacteria Fish Quarantine Class I Juanda, Surabaya. The purpose of this study was to know kind bacteria on the seeds cantang grouper from nursery pond at fisheries center brackish water aquaculture, Situbondo. The method used in this research is an observation method. Observation is a research direct to the object for a close look at the activities undertaken. The data obtained from the study of isolation and identification of bacteria on the seed grouper cantang analyzed descriptively and present...

Deaths from COVID-19 are increasing in patients with comorbidities. One of the most common comorbidities is diabetes mellitus. The researchers wanted to see how having diabetes affected the mortality rate of COVID-19 participants. This investigation is a case control observational analytical study. Different types of people, called “cases,” and “controls,” complete the research sample. Each group had 68 responders, for a grand total of 136. Medical records from COVID-19 patients treated at Airlangga University Hospital, Surabaya, between March 2020 and September 2021 serve as the study’s secondary data source. The purpose of this study’s data analysis is to calculate an odds ratio. Patients with COVID-19 with concomitant diabetes mellitus had an increased risk of death, and this risk increased with age, gender, and COVID-19 symptoms. In contrast, education, occupation, and laboratory results were not significantly related to mortality among COVID-19 individuals with concomitant diabetes mellitus (GDA status). The results of this study show that COVID-19 patients with concomitant diabetes mellitus are at a higher risk of death if they are over the age of 65, if they are male, and if they have severe symptoms.
