Abstract

The increase in food demand is not in line with the increase in the amount of production and quality of agricultural products. The strategy to increase agricultural production so far has been carried out through the provision of chemical synthetic fertilizers, this strategy has a negative impact on the quality of agricultural land, namely a decrease in the essential organic elements of the soil which are needed by plants. Organic farming is a necessary solution to restore land quality and Bacillus laterosporus is a microorganism that has the ability to produce various beneficial metabolites for plant growth and maintain soil fertility. B. laterosporus is a microorganism that requires a high-quality carbon source to produce high-quality metabolites, so it requires natural carbon sources that are cheap, easy to obtain and not widely used by humans, such as old coconut water, nira and molasses. The aim of the study was to determine the difference in the germination rate of soybeans treated with B. laterosporus suspension with different natural carbon sources so that the best natural carbon source for the growth of B. laterosporus could be identified as an essential component of quality organic fertilizer. Soybean germination rate was measured and observed and compared with the control. The results showed that the provision of natural carbon sources had a good effect on the growth of the number of bacterial cells and the germination rate of soybean seeds.

Abstract

Staphylococcus epidermidis is a gram-positive bacterium that can cause skin infections, one of which is acne. Acne (acne vulgaris) is a chronic inflammatory disease of the pilosebaseus unit characterized by the presence of blackheads, papules, pustules, nodules, cysts, and scars. Acne often occurs on the skin of the face, neck, chest and back. Although acne is not fatal, it is quite troubling because it can reduce self-confidence, especially those who care about appearance. The purpose of this study was to identify the antibacterial activity of suruhan leaf extract (Peperomia pellucida (L.) kunth) against Staphyloccocus epidermidis bacteria. The research method with well diffusion is to see the presence of clear zones formed around wells that show the inhibition of the growth of Staphyloccocus epidermidis bacteria by Peperomia pellucida (L.) kunth leaf extract. The object of study was the extract of uruhan leaves and bacteria Staphyloccocus epidermidis. Data were obtained using primary data from observation or direct observation of the area of inhibition zone of uruhan leaf extract against Staphyloccocus epidermidis bacteria. From the results of the study showed that there was an inhibitory power of the leaf extract against Staphyloccocus epidermidis bacteria.

Abstract

Black cincau is a food that is consumed by many people. Black cincau is used as a mixture of drinks and facilitates the digestive system. Black cincau is widely traded in traditional markets, but the processing and presentation of blackcincau often ignores cleanliness or is unhygienic. Some are sold without special packaging and placed in open containers. Such conditions allow black cincau to be contaminated by dust and bacteria. Bacteria that often contaminate food are Coliform bacteria such as Escherichia coli. Some of the diseases caused by E. coli include; diarrhea, urinary tract infection, sepsis, and meningitis. The aim of this study was to describe the E. coli bacteria contaminating black cincau in the Malang city market. This type of research uses a descriptive method, namely identifying Escherichia coli bacteria by means of the MPN test. The results showed that there were two out of a total of five positive samples containing E.coli bacteria. The presence of E.coli bacteria in positive samples was indicated by the presence of metallic green colonies on EMBA media

Abstract

Hepatitis B virus infection is the main cause of acute and chronic hepatitis, cirrhosis and liver cancer, 25% of whom experience jaundice. Blood transfusion is one of the most common routes of HBV transmission. The purpose of this study was to determine the prevalence of reactive and non-reactive HBsAg in the West Lombok Indonesian Red Cross unit. This type of research is descriptive, carried out in June 2022 at the West Lombok Indonesian Red Cross Unit. The results showed that the largest number of donors were men (12,201 people) and the age group of 25-44 years (4,342 people).

Abstract

The hospital is a health service institution that provides complete individual health services by providing inpatient, outpatient and emergency services. Plenary Health Services, namely health services that include promotive, preventive, curative, and rehabilitative. The availability of medical record file storage racks in health care facilities is very important in maintaining security and avoiding damage to patient data. The file rack is a place to store archives or medical record documents which aim to facilitate storage and retrieval of medical record documents in the filing room and maintain the confidentiality of medical record documents. The storage of medical record files can exceed the capacity due to the large number of new patient visits and the disproportionate file shelves. Planning or procuring storage racks based on the number of medical record documents stored, the shape of the racks and the size of the storage racks according to ergonomic standards, namely storage racks can be in the form of roll o'pack racks and taking into account the area of an available room. Calculation of the need for shelves is done by using the smallest quadrant calculation. Calculations are made based on the number of new patient visits in the previous 5 years, namely 2018 to 2022. Based on the calculation results, the results show that the need for shelves for the next 5 years is 3 shelves.
