Background: well water provide water that comes from a layer of soil that is relatively close to the ground surface, therefore it is easily exposed to contamination through seepage. In general, seepage comes from human excreta, latrines or latrines and animals, as well as from well waste itself, either because the floor or the sewerage are not impermeable to water. The condition of construction and the way the well water is drawn can also be a source of contamination, for example wells with open construction and drawing water with a bucket. One of the fecal contamination bacteria found in well water is Escherichia coli. Alum (Aluminum sulfate) is one of anti-microbial.Objective: To determine the effect of alum with concentrations of 5%, 10% and 15% on the amount of Escherichia coli in well waterMethod: explanatory research (explanatory research) which is to explain the relationship between variables through comparison and hypothesis testing, using a quasi experimental design method with the experimental design used in this study is Completely Randomized Design with 3 repetitions.Results: The results of the ANOVA test on the content of E. coli with various concentrations obtained a P value of 0.000 an alpha value of 0.05, indicating that there was a significant difference in the observed concentrations.Conclusion: Alum with concentrations of 5%, 10% and 15% affected the number of Escherichia coli in well water. The higher the concentration of alum, the better in inhibiting the growth of E.coli bacteria in well water.Conclusion: Alum with concentrations of 5%, 10% and 15% affected the number of Escherichia coli in well water. The higher the concentration of alum, the better in inhibiting the growth of E.coli bacteria in well water.

To evaluate the Q/H strength ratio, before and after the isotonic exercises. The Quasi experimental design was selected in this study. 50 female patients with knee osteoarthritis and disturbed Quadriceps – Hamstring (Q/H) ratio were assessed through Visual Analog Scale (VAS), Range Of Motion, Kellgren-Lawrence Scale and Repetition Maximum (RM). All of the patients were assessed at 1st visit, and then 15 sessions of isotonic exercises were given. They were examined again at 15th day to assess the effects of isotonic exercises on Q/H ratio. There was a significant difference in Q/H ratio before and after isotonic exercises. The average Q/H ratio before an exercise was less (0.8712 ± 0.1174) as compared to the ratio taken after exercises (0.9832 ± 0.1127). The P-value was less than 0.05 that was significant. The strength of quadriceps and hamstring muscles were increased, hence reduced the intensity of pain. The isotonic exercises were found to be effective for strengthening of quadriceps and hamstring muscles. There was a significant increase in Q/H ratio after isotonic exercises, with improvement in pain and ROM. This may improve their daily functional activities.

X bakery has 51 workers and produces approximately 60.000 pieces of bread in a day for nine working hours. Most of the production activities are manually handled and only. The low-level musculoskeletal pain reported by 92% of packaging workers. This study aims to analyze the effectiveness and ideal duration of stretching exercise in reducing musculoskeletal disorders (MSDs) among workers. Using quasi-experimental design, 51 workers involved as respondents who were asked to do a simple stretching exercise in specific duration, five days a week in at least 4 weeks. The MSDs score were measured using the nordic body map (NBM) questionnaire. Intervention divided into 4 categories based on the duration. There is lower level of musculoskeletal pain among all exercise group in average, but comparison test doesn’t show a significant difference compared to control group (p-value=0.232). The group with 15 minutes exercise is the only group that significantly difference compared with the control group (p-value=0.020). The workers with 15 minutes stretching exercise, five days a week tend to have 5.16 % lower level of musculoskeletal pain compared to the control group. Another type of exercise and various durations might be needed as comparison to obtain more representative result.

Memorizing Al-Qur'an is an effort to maintain the purity of the Al-Qur'an. The Qur'an tahfidz program is one of the activities intended to prevent the Qur'an from changing and falsifying either partially or completely. As the name implies, this program is applied to tahfidz Qur'an student to memorize Al-Qur'an under the guidance of their teacher. Memorization ability is determined by memory capacity which indicates brain health, one of which is influenced by the supply of oxygen to the brain. One way to maintain brain oxygenation is the management of deep breathing exercises combined with archery. The purpose of this study was to determine the effect of deep breathing exercises management in archery to achievement of memorizing the Qur'an. This research was held at SMP Ad-Dhuha Jember with a quasi-experimental one group pretest-posttest design method and was conducted in April-June 2019. The type of sample used was a total sampling of 34 respondents. Data analysis used the Wilcoxon Signed-Rank Test. The results showed an increase in the achievement of memorizing Al-Qur'an among students of the tahfidz Qur'an after managing deep breathing exercises with archery. Data analysis with alpha (α) <0.05 indicates a p value of 0.000 so that Ho is rejected. Thus there is an effect of deep breathing exercises management in archery on the achievement of memorizing the Al-Qur'an. A strong memory is needed to keep memorizing Al-Qur'an. To help increase the memory capacity of the brain, it requires an adequate supply of oxygen. Deep breathing exercises management combined with archery can be a way to maintain brain oxygenation. This exercise focuses on fullfiling oxygen needs, which in the process of memorizing the brain's memory functions are widely used.

The aim of this study was to investigate whether there was significant difference on the students’ reading comprehension of narrative text between those who were taught through Cooperative Integrated Reading and Composition (CIRC) method and those who were not. Forty-nine students were selected as the sample and quasi-experimental, non-randomized pre-test and post-test design were employed. The analysis of covariance showed that the students who were taught by using CIRC method statistically outperformed those who were not on their reading comprehension of narrative text, (F (1, 48) = 13.56, p < .05). This result implies that CIRC is an effective method to teach reading comprehension, particularly on narrative text. Since this study only focused on narrative text, future researchers might be interested to seek the effect of CIRC on other text genres. Similar study though may be conducted with a randomized design of larger population.

Diarrhea is defecation with a frequency more often than usual (three times or more) a day (10 mL/kg/day) with a soft or liquid consistency, even in the form of water alone. Pathogenic bacteria, such as Escherichia coli, Salmonella typhimurium, and Shigella sp., play a role in many cases, to which antibiotics are prescribed as the first-line therapy. However, since antibiotic resistance cases are often found, preventive therapies are needed, such as consuming yogurt, which is produced through a fermentation process by lactic acid bacteria (LAB). This research aimed to determine the activity of lactic acid bacteria (Liactobacillus bulgaricus and Streptococcus thermophilus) in yogurt in inhibiting the growth of the pathogenic bacteria E. coli, S. typhimurium, and Shigella sp. The research applied in vitro with the liquid dilution test method and the true experimental design research method with post-test-only and control group design. The design was used to see the inhibitory effect of yogurt LAB on the growth of E. coli, S. typhimurium, and Shigell sp. to compare the effect of several different yogurt concentrations, namely 20%, 40%, 60%, and 80%. The results of the Least Significance Different analysis showed that there was a significant difference between yogurt with a concentration of 0% and that with various concentrations in inhibiting the growth of E. coli, S. typhimurium, and Shigella sp. with a p-value of &lt;0.05.
