Indonesia has a high diversity of potential medicinal plants, which are the second-largest number of indigenous medicinal plants in the world. Syzygium polyanthum, known as Indonesian Bay Leaf or Salam, easily found, widely used in Indonesia as a spice in cooking and traditional medicine. Salam contains secondary metabolites such as flavonoids, alkaloids, tannins, essential oils, sesquiterpenes, triterpenes, phenols, steroids, and saponins. Staphylococcus aureus and Staphylococcus epidermidis are the main bacteria that cause commensal infection and the most common nosocomial infections. This study aims to know the antibacterial activity of the Salam ethanolic extract against Staphylococcus aureusand Staphylococcus epidermidis bacteria. Salam leaves were extracted by 70% ethanol in the maceration method. Antibacterial activity was conducted by the disk diffusion method. The extract exhibits moderate activity (10.51±0.3 mm) at 75% of concentration and low activity (3.69±0.4 mm) at 100% of concentration against Staphylococcus aureus and Staphylococcus epidermidis respectively. The test showed that salam leaves extract had antibacterial activity against Staphylococcus aureus and Staphylococcus epidermidis.

Pandan leaves have been researched and have effectiveness in the treatment of burns. The process of healing burns takes a long time and cause a hard tissue because it loses its elasticity, making it difficult to penetrate. In this study, pandanus leaves were formulated into the nanovesicle carrier system, namely trasfersom. Transfersomes have the ability to deform, namely the ability to reduce the particle size 5-10 times from the original size when passing through the gaps between cells so that transfersom can increase the penetration of active substances. The three formulas used are based on the ratio of concentrations of trasfersome vesicles, namely phospholipids and span 80. Formula 1 is (90:10), Formula 2 (85:15) and Formula 3 (80:20). The best formula is determined based on transfersom characterization, including particle size and PDI (solidispersity index), zeta potential, entrapment efficiency, deformability, and TEM particle morphology. The results showed that Formula 3 (80:20) is the most stable formula with an average particle size of 730.1 ± 4.9 nm, PDI value <0.7, zeta potential - 9.94 ± 1.02 mV, efficiency absorption 80.23%, and the deformability value 6.225.

Masons are regularly exposed to air pollution in the workplace The pollution exposure received by them is a risk factor for respiratory problems. Most of the masons had insufficient knowledge that is very important for the management of a person's illness. The purpose of this study was to determine relationship of knowledge on respiratory disorders with lung function in masons in east surabaya. This research was an observational study with a cross-sectional design with a purposive method.The research was conducted from April to July 2019 in the East Surabaya area. The variables that will be observed in this study are the level of knowledge of risk factors, symptoms, and treatment and therapy regarding respiratory disorders. In this study, there were 158 respondents consisting of 79 groups with impaired lung function and 79 groups without lung function disorders. Most of the level of knowledge of both groups was good in risk factors and treatment of respiratory disease, but instead on the symptoms regarding respiratory disease. The research showed that there was a relationship between the level of knowledge about risk factors for respiratory disease (p(0.223)<0.05) and lung function, but there was no difference in knowledge about symptoms (p(0.745)<0.05) and treatment (p(0.741)<0.05) respiratory disease with pulmonary function. Therefore, it was necessary to plan further educational programs in increasing masons' knowledge of respiratory symptoms so that they could catch respiratory diseases earlier.

The recent public health crisis is threatening the world with the emergence of the spread of the new coronavirus 2019 (2019-nCoV) or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This virus originates from bats and is transmitted to humans through unknown intermediate animals in Wuhan, China in December 2019. Advances in technology have opened opportunities to find candidates for natural compounds capable of preventing and controlling COVID-19 infection through inhibition of spike proteins of SARS-CoV-2. This research aims to identify, evaluate, and explore the structure of spike protein macromolecules from three coronaviruses (SARS-CoV, MERS-CoV, and SARS-CoV-2) and their effects on Angiotensin-Converting Enzyme 2 (ACE-2) using computational studies. Based on the identification of the three spike protein macromolecules, it was found that there was a similarity between the active binding sites of ACE-2. These observations were then confirmed using a protein-docking simulation to observe the interaction of the protein spike to the active site of ACE-2. SARS-COV-2 spike protein has the strongest bond to ACE-2, with an ACE score of −1341.85 kJ/mol. Therefore, some of this information from the results of this research can be used as a reference in the development of competitive inhibitor candidates for SARS-CoV-2 spike proteins for the treatment of COVID-19 infectious diseases.

Sedangkan untuk ketiga jenis minuman lainnya, jumlah kafein yang didapat lebih rendah dari yang diharapkan, dan masih di bawah batas maksimal yang diperbolehkan.

The herbs Carissa spinarum, Physalis minima and Toddalia asiatica have traditionally been used in healing diabetes, malaria and pneumonia by the communities around the Kisii region, Kenya. However in the available literature, there is scanty information on effectiveness of different plant parts of the herbs in healing the ailments. The objective of this study was to investigate the potential antimicrobial and antifungal activity of methanolic extract of whole plant Physalis minima, leaf and root of Carissa spinarum and Toddalia asiatica against gram positive bacteria Staphylococcus aureus (ATCC 25923), gram negative bacteria Escherichia coli (ATCC 25922) and fungus Candida albicans (ATCC14053). Antibiotic disc methicillin, cotrimoxazole, chloramphenicol, gentamicin, ampicillin, nalidixic and nitrofurantoin were used in the study. In each herb, plant part was extracted by soaking in methanol/dichloromethane in ratio 1:1 for a week, filtered, concentrated by rotary vapor and cooled. The same process was repeated three times for all samples. The study was conducted by agar well diffusion method. Methanolic root extract of Toddalia asiatica showed highest antibacterial activity against Staphylococcus aureus (ATCC 25923), root extract of Carissa spinarum had highest antibacterial activity against Escherichia coli (ATCC 25922) while root extract of Toddalia asiatica showed highest antifungal activity. It was concluded that root extract of Toddalia asiatica showed highest antibacterial activity 16.7mm against Staphylococcus aureus(ATCC 25923), root extract of Carissa spinarum had highest antibacterial activity 10 mm against Escherichia coli (ATCC 25922) while root extract of Toddalia asiatica had highest antifungal activity 18 mm against Candida albicans.
