Abstract

Food Additives are ingredients that are usually not used, not the main ingredient of food, these ingredients are intentionally added to food. One food that is often added with food additive is jam. Jam is a food made simply from sour-tasting fruits such as strawberries, grapes, blueberries and pineapple. Jam making is strongly influenced by the type of fruit used, the temperature and the jam making process (Javanmard and Endan, 2010). The types of jam bread from various brands and unbranded ones can be found in traditional markets as well as in modern markets. Synthetic dyes are generally cheaper, easier to use, stable, better coloring power, and have a wider color range (Nollet, 2004). Some synthetic dyes are so harmful to health that their use is not permitted. One example, the red color given to food is Rhodamin B (Djalil et al., 2005). The type of research used is qualitative research conducted to determine the type of coloring substances contained in branded jam bread and unbranded jam bread using the paper chromatography method. Qualitative examination with paper chromatography method and this examination to see the type of coloring substances contained in the sample. Based on the results of the qualitative analysis, it is known that of the 4 samples, 2 branded jam samples and 2 unbranded jam samples use permitted coloring agents, namely Sample A1 does not contain synthetic dyes and Sample B does not contain synthetic dyes. After qualitative examination, it was found that there was no use of coloring agents that were not permitted in the branded jam samples. In the unbranded jam after qualitative examination was not found the use of coloring substances that are not permitted. Rhodamine B is a textile dye that can trigger diarrhea, allergies, cancer or kidney damage. After the research was conducted, it was found that from the branded and unbranded jam samples, no synthetic dyes were found. Based on the results of the examination on the types and synthetic dyes of branded jam and unbranded jam circulating in Keru Narmada Market, it can be concluded as follows: The results of the examination of branded and unbranded jam found no synthetic dyes.

Abstract

Emergency patient services are services that require immediate, precise and careful help to prevent death and other possibilities. In emergency services, time is very important as time saves lives (time saving is life saving). The purpose of this study was to determine the relationship between patients’ wait-time and the level of anxiety in the Emergency Room (ER) X Hospital. The research design used in this study was analytic research with a cross sectional approach. The samples of the study were the patients in emergency department as many as 101 respondents selected through purposive sampling technique. In order to collect the data, the researcher spread out questionnaire to the samples, and then analyzed them by using rank sperm. The results showed that out of 101 respondents, 75 (74.3%) waited for a short time. Henceforth, they were categorized into the short wait-time category. 26 respondents (25.7%) waited for a long time and categorized into long wait-time 26 respondents. The patients's anxiety level was mostly in the moderate level experienced by 62 respondents (61.4%), and the lowest is in the mild anxiety category, experienced by 18 respondents (17.8%). This could also be seen from the analysis test value of p value that was lower with a significant level of 0.05 then p value <α so that Ha was accepted and H0 was rejected or vice versa. This study could suggest that there was a relationship between patients’ wait-time and the level of anxiety in the Emergency Room at the X Hospital. Therefore, the patients should not stay too long in the ER.

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

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

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.
