Covid-19 has an impact on adolescents, both directly in the form of exposure to the virus and in the form of secondary effects caused by efforts to stop transmission. Adolescence is a transitional period where critical thinking begins, but is sometimes controlled by an unstable emotional state. Changes in conditions caused by the Covid-19 pandemic can affect the psychosocial and consumption patterns of adolescents. This study aims to determine adolescents' perceptions of Covid-19 and their consumption patterns during the pandemic. This is a cross-sectional study with a sample of 95 adolescents who were sent randomly linked questionnaires during the first week of September 2020. Data analysis was carried out using descriptive statistics and graphs. Teens who were not sure and doubted the covid-19 virus were 14.7% and considered it a conspiracy, because there was no clear evidence and information. Changes in consumption patterns were felt by 37.9% of adolescents during a pandemic. Adaptation to new habits that was most difficult for adolescents was to avoid crowding and only 38.7% could do it. A small proportion of teenagers are unsure or doubt the existence of the Covid-19 virus, due to lack of clear information. The pandemic causes stress for teenagers and has an impact on changing consumption patterns. The adoption of new habitual adaptations has not been fully carried out, even though most teenagers are convinced of the Covid-19 virus. The need for clear information about the covid-19 virus and strengthening the application of health protocols in adolescents.

This study aims to isolate endophytic bacteria of sweet sorghum plants and characterize their ability as plant growth promoting. The characters tested in this study were the ability of endophytic bacteria in N fixation, phosphate dissolving, and IAA production to be developed as biological fertilizer agents. Twenty-four isolates were isolated from the roots, stems and shoots of sweet sorghum. The results of bacterial DNA fingerprint screening showed that 11 groups of endophytic bacteria had different fingerprints. Isolates capable of N fixation were grown on LGI media and showed a change in the color of the medium. The nifH gene detection is also carried out to determine endophytic diazotrophic bacteria. Isolate bacteria that can dissolve inorganic phosphate were tested using Pikovskaya media. Testing the ability of isolates to produce IAA was carried out by adding Salkowski's reagent to the bacterial culture and measured quantitatively with a λ 530 nm spectrophotometer. The results showed that two endophytic bacterial isolates proved to be diazotrophic and three isolates were able to dissolve phosphate, while one isolate was able to produce IAA. PA2 isolate showed ability in all the characters tested, namely N fixation, phosphate solvent and IAA producer.

Campylobacterosis is an infection disease caused by bacteria from Campylobacter genus, especially Campylobacter jejuni (C. jejuni) species. This Gram-negative bacteria has very mall size, rod-shaped, thin and some are spiral shaped. C. jejuni does not have spore, catalase positive, nitrat reductor, and highly motile with flagella located at one or two ends of its body. It’s growth is microaerophilic, grow optimally with low oxygen levels. In the growth media, all Campylobacter sp grew well at pH 5.5-8.0. Colonies appear round, smooth and convex. Campylobacteriosis is zoonotic, which mean it can be transmitted from animals to humans. Bacteria that enter the human body produce a toxin, Cytolethal Distending Toxin (CDT), which is one of the pathogenic factors. Clinical manifestations caused diarrhea, sometimes to bloody, abdominal pain, fever, nausea and vomiting. In humans and animals, most cases are asymptomatic. Laboratory tests to support a definite diagnosis of infection by Campylobacteriosis are necessary. Based on this, the purpose of writing this article is to link the diagnosis and pathogenesis of Campylobacteriosis with microbiological examination. Microbiological examinations that can be done are microscopic, culture and non-culture. Currently, non-culture techniques being developed include Polymerase Chain Reaction (PCR), Epidemiological typing system and serology.

Bromelain is proteolytic enzyme extracted from pinepple (Ananas commosus L.) and potents as anticancer. The aimed of this study was to determined the toxicity effect of bromelain extract from pineapple fruit (Ananas commosus L) with brine shrimp lethality test (BSLT) methods. Crude extract of bromelain was obtained by addition of natrium acetat buffer pH 6.5 to pineapple fruit and was setrifugated with 3500 rpm of speed. Bromelain toxiciy was determined by incubated 15 artemia salina Leach (48 aged old) in various concentration of bromelain extract; 3.000 ppm, 2.000 ppm, 1.500 ppm, 1.000 ppm, 500 ppm and 0 ppm for 24 hours. At the end of incubation period, mortality percentages and LC50 were calculated. The result shown that there were increased in mortality percentage as bromelain concentration increased. LC50 value of bromelain exctract was 9.000 ppm. This value indicated that bromelain extract from pineapple fruit had low toxicity effect since its LC50 value were under 1000 ppm. Inconclusion, crude bromelain extract from pineapple fruit did not show anticancer potential based on this study.
