Abstract

Acne is a dysbiotic condition caused by Cutibacterium acnes and Staphylococcus epidermidis bacteria. Gribong (Archidendron clypearia (Jack) I.C. Nielson) has been empirically used as a treatment for facial problems by the people of Bangka Belitung. This study aims to test the potential of ethanol extract and fractions of gribong leaves against two bacteria that cause acne. This study is an experimental research conducted in four stages, namely phytochemical testing, antibacterial activity testing, minimum inhibitory concentration testing, and minimum bactericidal concentration testing and equivalence tests against clindamycin antibiotics as positive controls. The results of this study showed (1) Secondary metabolites contained in 96% ethanol extract, ethyl acetate fraction and n-butanol fraction are phenolics, flavonoids, tannins and saponins. Terpenoids were only found in the ethanol extract. The ethyl acetate fraction found no alkaloids and the n-hexane fraction contained only steroids. (2) The 96% ethanol extract, ethyl acetate fraction and n-butanol fraction had antibacterial activity. (3) The highest antibacterial activity was shown by the ethyl acetate fraction with KHM on C. acnes at 0.375% and on S. epidermidis at 1% and KBM for both bacteria at 2.5%. (4) The equivalence value of antibacterial activity of fractions to antibacterial antibiotic clindamycin is still relatively low but still has good antibacterial activity. In conclusion, the ethanol extract and its fractions have potential as anti-acne against C. acnes and S. epidermidis bacteria.

Abstract

This study aims to identify the factors influencing nurse compliance in implementing nursing care procedures at RSUD Praya Lombok Tengah, focusing on the surgical, internal medicine, and pediatric wards. This observational analytic study uses a cross-sectional design involving 36 nurses as respondents. The variables analyzed include education, salary, rewards, work interaction, and safety. The research instruments used include questionnaires, interviews, and checklists. The questionnaire was used to measure respondents' demographics, salary, rewards, work interaction, and safety, while compliance was measured using a checklist. Data analysis using chi-square and regression tests showed that none of the independent variables had a significant influence on nurse compliance. The logistic regression test results showed significance values for income (Sig. = 0,487), work interaction (Sig. = 0,721), rewards (Sig. = 0,516), and safety (Sig. = 0,571), all of which were greater than 0.05, indicating no significant influence. However, it can be concluded that a holistic approach still plays an important role in improving nurse compliance.

Abstract

Most Producing Production Ability (MPPA), also known as Expected Production Ability (EPA) in dairy cattle, indicates the ability to produce milk that can be passed down to offspring. The objective of this study is to obtain the repeatability values of morning and evening milk production in the second and fourth lactations of Friesian Holstein (FH) dairy cows as a basis for estimating MPPA values, ranking, and the relationship of milk production in livestock. This case study uses a sample determined by purposive sampling technique, focusing on cows with recorded second and fourth lactations. The research was conducted at a local dairy farm in the Pujon area of Malang Regency. The sample consisted of 12 cows with the same day, month, and lactation period. Data were analyzed using variance analysis, correlation, and regression. The results showed that the repeatability value of morning milk production ranged from 0,63 to 0,99, categorized as high, while the repeatability of evening milk production ranged from 0,39 to 0,99, categorized as moderate to high. The MPPA values from the study ranged from 3.602 liters per cow to 10,811 liters per cow (morning milk production) and from 1,237 liters/cow to 5,024 liters/cow (evening milk production). The ranking of cattle based on MPPA morning milk production ranged from 1 to 7. The relationship between morning and evening milk production is represented by the equation Y = 0,6213, X = 1,7587 with a determination coefficient of 88,68%.

Abstract

This study aims to investigates the correlation between parenting styles and adolescent sexual behavior at SMA Negeri 3 Mataram using an observational analytic design with a cross-sectional approach. Data were collected from 69 11th-grade social science students via a questionnaire assessing parenting styles and sexual behavior. Results indicated that (1) 59.4% of respondents experienced permissive parenting, while 40.6% encountered democratic parenting; (2) respondents who have permissive parenting, 5.8% demonstrated negative sexual behavior, in contrast to the uniformly positive behavior observed in adolescents with democratic parenting; (3) the results of Fisher's exact test are a significance value of 0.141, indicating no statistically significant relationship between parenting styles and adolescent sexual behavior; (4) trend suggests that democratic parenting, which balances freedom and control, is associated with positive adolescent sexual behavior. Thus, these findings highlight the importance of promoting democratic parenting and comprehensive sexual education to reduce risky behaviors. Recognizing cultural nuances and enhancing parental involvement are essential for effective adolescent sexual health prevention strategies.

Abstract

This study aims to investigates the link between early marriage and parenting styles among parents of children aged 3-5 years in Awang Village, Central Lombok, Indonesia. This study employs an observational analytic design with a cross-sectional approach. Data were gathered from 42 mothers who married before the age of 20. The research instrument is a questionnaire to collect information about socio-demographic and parenting style information, categorized as democratic, authoritarian, and permissive. Data analysis was conducted in two stages: univariate and bivariate analysis. The results of this study are that (1) a significant association between early marriage and authoritarian parenting styles, with 55% of mothers who married at or below 15 years old displaying authoritarian behavior, and 80% exhibiting permissive tendencies, (2) democratic parenting was exclusive to mothers who married at 16 years or older. Higher education levels were linked to democratic parenting, (3) a significant relationship between early marriage and authoritarian parenting, proven by statistical analysis using Fisher’s Exact Test (p = 0.001). The results suggest that early marriage leads to less supportive and more controlling parenting practices, negatively impacting child development. Thus, addressing socio-economic factors and improving educational opportunities are vital to mitigating the adverse effects of early marriage on parenting styles and child development.
