Escherichia coli is a bacterium that typically resides as a normal flora in the gastrointestinal tract of humans and animals. However, certain strains of E. coli can cause infections in humans. Therefore, antibiotics are needed to inhibit the growth of these infection-causing bacteria. The increasing cases of antibiotic resistance in E. coli necessitate alternative therapies, including the use of natural substances. In West Kalimantan, one potential source is the Pontianak Orange (Citrus nobilis var. microcarpa). This plant contains secondary metabolites that can be used for medicinal purposes, such as the juice extract. The compounds within these secondary metabolites possess antimicrobial properties that could be used as antibacterials. To determine the antibacterial potential of Pontianak Orange juice (Citrus nobilis var. microcarpa) against Escherichia coli. This study utilized an experimental design featuring a post-test only group design. Phytochemical analysis indicated that Pontianak Orange juice (Citrus nobilis var. microcarpa) contains phenolics (+), alkaloids (+), and terpenoids (++). Antibacterial activity testing at all concentrations (25%, 50%, 75%, and 100%) showed no inhibition zones. The juice of Pontianak Orange (Citrus nobilis var. microcarpa) did not show antibacterial effects against the growth of Escherichia coli bacteria.

This study analyzes variation skills as a strategy to improve the effectiveness of learning in early childhood. Early childhood has unique characteristics, such as short attention span and high curiosity, so variation in learning is essential to maintain their interest and engagement. Variation includes the use of various methods, media, teaching styles, and activities, which are adjusted to the developmental needs of children. Through a qualitative approach based on literature studies, this study found that variation in learning can improve children's learning motivation, concentration, and social and emotional skills. Variation also supports multisensory-based learning that strengthens conceptual understanding. The conclusion of this study emphasizes the importance of training for teachers to master variation skills in learning, in order to create meaningful and enjoyable learning experiences for early childhood.

Fasting, as one of the main acts of worship in Islam, has a deeper meaning other than just enduring hunger and thirst. It is hoped that this practice can shape individual character, increase spiritual awareness, and have a positive impact on physical and mental health. However, although the spiritual benefits of fasting have been widely discussed, scientific research regarding the impact of fasting on health is still limited. Therefore, this study aims to explore the impact of fasting on physical and psychological health and its influence on self-development. This research uses quantitative methods with an experimental design. A total of 100 participants consisting of individuals who fasted and non-fasted during Ramadan were randomly selected. Data was collected through questionnaires regarding physical and psychological health as well as direct observation of lifestyle before and after fasting. Body mass index (BMI), blood pressure, and stress levels were also measured at two time points: before and after the 30-day fasting period. Data analysis was carried out using the t test to see significant differences between the fasting and non-fasting groups. The results of the study showed that fasting had a significant effect on weight loss, reduced cholesterol levels, and a more stable increase in blood pressure. Psychologically, participants who fasted experienced reduced levels of anxiety and increased concentration and peace of mind. However, this effect is temporary and is more visible in individuals who had a healthy lifestyle before fasting. In addition, most respondents reported increased spiritual closeness and increased feelings of empathy towards others after fasting.

The study investigated how Cola nitida affects the sweat concentrations of sodium (Na), potassium (K), and chloride (Cl) in male and female subjects. Sixty healthy participants (30 males, 30 females) aged 18–28 years, with varying body weights (underweight, normal weight, overweight), were selected. Subjects were exposed to three conditions: normal chamber temperature (27°C, 70% RH), raised temperature (37°C, 90% RH), and exercise at normal temperature (27°C, 70% RH) while riding a bicycle ergometer at 750J/min for 20 minutes. Prior to the experiment, 0.5g/kg body weight of Cola nitida was consumed, followed by a 90-minute rest. Sweat samples were collected to measure ion concentrations. Results showed no significant changes in sodium (Na) concentrations between males and females under normal and raised temperature conditions. However, under exercise conditions, there was a significant increase in sweat Na in female underweight subjects compared to males. Regarding chloride (Cl), there was no significant difference between males and females under all conditions. For potassium (K), significant increases were observed in the sweat of female underweight subjects compared to males in normal, raised temperature, and exercise conditions. Conversely, decreases in sweat potassium were noted in female normal weight subjects under normal conditions and overweight subjects under raised temperature and exercise conditions compared to males.

How Cola nitida could affect the urine calcium and magnesium concentrations of the male human subjects in comparison to the female counterpart were focused on. Sixty subjects (males=30 and females=30) and unaccustomed to Cola nut eating were involved. Their age range was between 18 and 28years. Three (3) sub-categories were involved: underweight=10, normal weight=10 and overweight=10. Hypertensive, renal and any subject with cardio-pulmonary-related conditions were exempted from the study. The normal chamber temperature, (RT=270C and RH=70%), the raised chamber temperature (RT =370C and RH=90%) were studied. Sequel to the foregoing, the subjects sat quietly in the sweat chamber for 20 minutes. The third experimental condition was the normal chamber temperature with exercise (RT=270C and RH=70%) and the subjects rode a bicycle ergometer at 750J/minute for 20 minutes. All of these happened prior to the consumption Cola nitida. Ahead of the experimentation in the sweat chamber, the subject urinated in a container in order for the timed urine volume to be measured and urine was again taken at the end of the experimentation that was also measured in order to obtain the actual urine volume within the given period. Thereafter, the urinary flow rate was calculated. The urine calcium and magnesium concentrations were likewise estimated. 0.5g/kg body weight of Cola nitida was given to each subject and chewed as a bolus. After swallowing, 50ml of deionized water was given to each subject to drink and the subject was allowed to rest for 90 minutes before being brought into the sweat chamber. The results showed that in respect to urine Ca ions concentration, no significant change was observed in a comparison between the males and females after the ingestion of Cola nitida under normal, raised temperature and exercise experimental conditions. As regards urine Mg ions concentration, no significant change was observed in a comparison between the males and females after the ingestion of Cola nitida under normal and exercise experimental conditions. However, there was a significant increase in Mg ions concentration in the female UW and NW subjects compared to the males after the consumption of Cola nitida under raised temperature condition.

The reason readiness matters are that children who are prepared for school will advance in their development. The term "school readiness" describes a child's ability to transition to school smoothly and successfully. Even among children of the same age, there are differences in a child's school readiness. The problem in today's society is that many parents think that the only aspect needed for children to enter primary school is the cognitive aspect, which includes the ability to write, read and count. The impact of this view is that many parents demand their children to be able to read, write and calculate after graduating from kindergarten because of the intense competition among favorite schools. In this study, a qualitative descriptive technique was used. The research was conducted at Ummul Habibah Pre-School, Klambir V Kebun village, Deli Serdang Regency. In this study, data collection methods used interview and observation. The three-pronged approach were used as data analysis—data reduction, data presentation, and conclusion drawing or verification. Based on the data result, the 5 children who were given the CPM and NST tests, had readiness to join the next school level. These children have adequate absorption and intelligence in solving problems and have adequate concentration. One of the intelligence factors in children's readiness to enter primary school can be explained that children who have high intelligence tend to have intelligent behavior in making decisions and solving problems. The results in the study illustrate that students who have high problem-solving test scores also have high scores in completing the readiness test (NST) and vice versa for students whose low problem solving test scores are also followed by low scores.

This research investigates the effect of adding active ingredients such as butterfly pea flower extract and eggshell powder on the physical and chemical properties of smart biodegradable film packaging.
