This study aimed to isolate and culture bacteria from well water samples as a first step in identifying microorganisms found in domestic water environments. Well water was chosen because it is one of the main water sources for communities, especially in rural areas, but is highly susceptible to contamination due to human activities such as household waste, agricultural waste, and poor sanitation systems. The isolation process was carried out using the pour plate and scratch plate methods using Nutrient Agar (NA) and MacConkey Agar (MAC) media, which function to detect various types of bacteria, both pathogenic and non-pathogenic, including gram-positive and gram-negative bacteria. Samples were incubated at 37°C for 24–48 hours to allow colony growth. After the incubation period, the growing colonies were observed morphologically based on the color, shape, and edge of the colonies. Next, the colonies were cultured to obtain pure cultures for further analysis. Preliminary results showed a diversity of colony shapes indicating the presence of several bacterial species, such as Escherichia coli, Pseudomonas sp., and possibly Enterobacter sp., which are indicators of air quality and the level of fecal contamination. This study provides a preliminary overview of the microbiological status of well water and the importance of regular testing of domestic water sources. Early identification through isolation and culture is crucial for mitigating public health risks and providing a basis for any necessary air treatment or sanitation interventions. Therefore, the results of this study are expected to serve as a reference for the community and government in sustainably maintaining the quality and safety of well water. The recommended next step is to conduct antibiotic resistance testing to determine the potential hazards of the identified pathogenic bacteria.

Significant physical and psychological changes occur throughout pregnancy, especially in the third trimester (weeks 27–40).  Lower back pain, frequently caused by poor posture, changes in the curvature of the spine, and increasing body weight that shifts the center of gravity forward, is a common issue during this time.  Between 30% and 78% of pregnant women report experiencing lower back discomfort.  Maintaining physical health, endurance, and mental preparedness for childbirth are key objectives of prenatal exercise.  This study aimed to examine the effect of pregnancy exercise on lower back discomfort in third-trimester pregnant women at the Likupang Community Health Center.  The study used a one-group pretest-posttest design and was pre-experimental in nature, with the Likupang Community Health Center serving as the research site.  Fifteen pregnant women from the Likupang Community Health Center were chosen as the study sample.  The results indicated that pregnancy exercise had a significant impact on reducing back pain (p-value 0. 000), showing a clear effect between pregnancy exercise and the reduction of lower back pain (p-value 0. 000), as confirmed by the bivariate statistical test.  The findings suggest that pregnancy exercise can effectively alleviate lower back discomfort in third-trimester pregnant women.

The exploitation of natural resources through mining projects in Indonesia often has an impact on the lives of residents, both socially, economically, and environmentally. Although the government has established various regulations to protect the rights of affected communities, the implementation of this legal protection still faces various challenges. In this context, this research aims to analyze legal protection for residents in mining projects in Indonesia and examine the effectiveness of regulations that have been implemented. This research uses a normative juridical method using both a statutory and a conceptual approach. The former involves examining multiple legal provisions that govern mining and community protection, including Law Number 4 of 2009 concerning Mineral and Coal Mining, Law Number 32 of 2009 concerning Environmental Protection and Management, and various derivative regulations. The latter involves investigating legal theories that are pertinent to the defense of residents' rights, including the notion of sustainable development, the right to a healthy environment, and the rights of indigenous peoples to land and natural resources. This research does not involve case studies or interviews, but focuses on a normative study of the applicable legal system. Through an analysis of national and international legal instruments, this research is expected to provide academic contributions in identifying weaknesses in existing regulations and providing recommendations for policy makers in improving legal protection for residents affected by mining projects. Thus, this research can be a basis for strengthening more effective legal protection in maintaining a balance between the exploitation of natural resources and the rights of local communities.

The community is able to answer evaluative questions well and show skills in processing moringa leaves independently. In addition to increasing knowledge, the community also shows a commitment to implementing the results of counseling in daily life, including in efforts to reduce high blood pressure through the consumption of processed moringa leaves. This activity ran smoothly and had a positive impact on improving nutrition literacy and public health. It is hoped that this activity can be a model of sustainable community empowerment based on local potential.

β-lactam antibiotics are a very important group of drugs and are most frequently used in the treatment of bacterial infections, both in healthcare facilities and for self-medication. The advantages of β-lactams lie in their effectiveness and broad spectrum of action. However, the development of pharmaceutical preparations containing β-lactams still faces significant challenges, particularly related to the physicochemical stability of these compounds. The reactive ring structure of β-lactams makes them highly susceptible to degradation, particularly through hydrolysis. This degradation process can be accelerated by various environmental factors such as high temperature, changes in pH, humidity, and the presence of certain excipients and solvents in drug formulations. This article comprehensively reviews the various factors that influence the stability of β-lactams, both in solid and liquid pharmaceutical dosage forms, as well as in microbiological media. Furthermore, it also examines various innovative formulation approaches that have been developed to improve the stability of these compounds. These approaches include film coating technology, encapsulation, and crystal engineering, which have been shown to reduce the rate of degradation and extend product shelf life. Literature studies have shown that solid dosage forms are generally more stable than liquid dosage forms, primarily because exposure to water and solvents can accelerate hydrolysis. Distribution and storage of these preparations are also important aspects to consider in maintaining the quality and effectiveness of β-lactam antibiotic therapy. Therefore, β-lactam product development requires a holistic approach, encompassing not only formulation and production technology but also optimal distribution and storage strategies. The use of appropriate analytical methods is also necessary to monitor degradation products and ensure product safety and effectiveness throughout the shelf life.

The methods used include interactive lectures, group discussions, demonstrations on making oral rehydration solution (ORS), handwashing practice, and distribution of leaflets. The participants consisted of 30 mothers of young children in Bangun Rejo Village, Tanjung Morawa Subdistrict. Evaluation was conducted using pre-test and post-test knowledge assessments. The results of the activity showed a significant increase in mothers' knowledge regarding the prevention and management of diarrhea. Participants were able to identify diarrhea symptoms, practice making ORS, and were more prepared to take their children to healthcare facilities if dehydration signs were present. This activity demonstrated that community-based health education is effective in enhancing mothers' knowledge and preparedness in preventing diarrhea.

Indonesia, as an agricultural country, has a large population working in the agricultural sector. Agricultural activities often involve the use of chemicals that can cause skin disorders, one of which is contact dermatitis. Contact dermatitis is an occupational disease with a high prevalence, both globally and nationally. As a form of concern for the increasing number of dermatitis cases among farmers, a community service activity was conducted in Mlati Village, Grobogan Regency. This activity aimed to increase farmers' awareness and knowledge regarding contact dermatitis prevention. The intervention included educational sessions, interactive discussions, role-plays, pre- and post-tests, and the distribution of skin health information leaflets. The activity was carried out by the Health Promotion Team from the Faculty of Medicine, Semarang State University. The evaluation results showed an increase in participants' understanding of the symptoms of contact dermatitis by 11.86% of the 21 participants who attended. Materials considered important by participants included the importance of maintaining personal hygiene after contact with chemicals, as well as the use of personal protective equipment (PPE) during work. The participants' enthusiasm was also evident in their active participation in the discussion sessions and hands-on practice. However, there was still a lack of in-depth understanding of skin health care. This demonstrates the need for regular follow-up education to reinforce the program's positive impact. Overall, these activities demonstrate the critical importance of community-based health promotion in reducing the risk of occupational skin diseases and encouraging healthier and safer behavior changes in farmers.

Indonesia ranks fourth globally in terms of active Instagram users, with approximately 103 million users, positioning this platform as a strategic medium for hospitals to conduct promotion, health education, and audience engagement. Hospitals, particularly private institutions, have increasingly recognized the potential of social media in fostering strong brand images and maintaining public trust. This study aims to analyze the influence of marketing content on the brand image of Indriati Solo Baru Hospital, a private hospital that is active on Instagram and holds verified status. Employing a quantitative approach with an associative method, the research involved 100 respondents drawn from followers of the hospital’s official Instagram account, selected through incidental sampling. Data were collected via questionnaires and subsequently analyzed using simple linear regression. The results demonstrate that marketing content exerts a positive and significant impact on brand image, as reflected in the regression equation Y = 3.838 + 0.267X. Statistical analysis further revealed a significance value of 0.001 (<0.05) and a t-calculated score of 10.048, exceeding the t-table value of 1.984. The coefficient of determination (R²) was 0.507, indicating that marketing content accounts for 50.7% of the variance in brand image, while the remaining 49.3% is influenced by other factors beyond the scope of this study. Among the tested indicators, Decision Making and Life Factors demonstrated significant contributions, underscoring their role in shaping perceptions of brand image. Meanwhile, Persuasion, Reader Cognition, and Sharing Motivation functioned as supportive elements that reinforce but do not independently drive outcomes. These findings highlight the critical role of strategic content development in strengthening hospital brand image within digital spaces.

The Batanghari River is a vital water source in Jambi Province, used by the community for various purposes, including domestic, agricultural, and fisheries needs. However, with increasing human activities, such as the discharge of household waste, industrial waste, and agricultural waste, the river's water quality is at risk of microbiological contamination that can endanger public health and the environment. This study aims to identify the presence of bacteria in the Batanghari River water, in order to assess the potential for biological contamination that can negatively impact public health and the surrounding ecosystem. The method used in this study included taking water samples from several locations along the river. After sampling, bacterial isolation and identification were carried out using Nutrient Agar (NA) media using the pour method. The results of the isolation process showed the growth of bacterial colonies that varied in shape, size, and color, indicating microbiological contamination, especially by heterotrophic bacteria. These findings indicate that the Batanghari River water contains microorganisms that reflect the potential for microbiological contamination. Therefore, this study emphasizes the importance of regular water quality monitoring and the need for sustainable management measures to maintain the health of the ecosystem and surrounding community. With routine monitoring, it is hoped that potential contamination that could be harmful to health can be detected early. Furthermore, the results of this study are expected to form the basis for better policy-making in water resource management and increase public awareness of the importance of maintaining water quality for sustainable life and environmental health. This study provides a preliminary overview of the microbiological condition of the Batanghari River water and emphasizes the need for greater attention in water resource management to prevent negative impacts on health and the environment.

Successful development encompasses various aspects of community life and cannot be separated from progress in the health sector. Health is one of the key indicators in determining the quality of life of a population. Therefore, attention to health—especially for vulnerable groups such as the elderly—is of great importance. Regular health check-ups serve as a preventive measure to help the community detect illnesses early and encourage individuals to take an active role in maintaining their own health. Several types of examinations are commonly provided free of charge during community service activities, including blood pressure checks, random blood glucose tests, uric acid level tests, and cholesterol level screenings. These health checks are especially beneficial for the elderly, as they help monitor overall health conditions and enable early management of diseases to prevent further complications. In this activity, a total of 40 elderly individuals voluntarily participated in the health screening. The methods used included health education sessions and direct examinations of blood pressure, uric acid levels, and random blood glucose levels. The counseling was delivered using simple and clear language, and it included a question-and-answer session to help participants better understand the information provided. The results of the examinations showed that some of the elderly participants had high blood pressure and elevated blood glucose levels, which led to recommendations for follow-up visits to nearby healthcare facilities. Through this health screening initiative, the overall health quality of the elderly participants improved, and their awareness of the importance of early detection increased. This activity is expected to motivate the broader community to pay more attention to their health and to undergo regular health check-ups. By taking a proactive role in managing their well-being, individuals can reduce the risk of serious complications in the future and contribute to the creation of a healthier society overall.

This study investigates the monetary transmission mechanisms influencing inflation and exchange rates across seven Southeast Asian countries (Myanmar, the Philippines, Indonesia, Malaysia, Singapore, Thailand, and Vietnam) over the period 2010–2023, with special focus on the impact of the COVID-19 pandemic. The research addresses the problem of macroeconomic instability, particularly the volatility in inflation and currency values during crisis periods, and aims to identify the dominant monetary factors affecting these indicators. The study employs a mixed quantitative approach using Structural Vector Autoregression (SVAR), Panel Autoregressive Distributed Lag (ARDL), and Paired Sample t-Test to analyze the short-term and long-term relationships among key variables: Gross Domestic Product (GDP), investment, money supply (M2), interest rates, inflation, and exchange rates. Findings reveal that GDP is the most influential factor impacting both inflation and exchange rates, followed by money supply and interest rates. The variance decomposition analysis confirms that these monetary variables significantly explain macroeconomic fluctuations in both pre- and post-pandemic contexts. The t-Test further indicates statistically significant changes in inflation and exchange rates before and after the pandemic, highlighting the disruptive effect of COVID-19 on economic stability. The results demonstrate that inflation declined significantly in most countries during the pandemic, while exchange rate behavior varied depending on economic resilience and policy responsiveness. The study concludes that maintaining macroeconomic stability requires not only monetary policy coordination but also effective public health crisis management. This research contributes to the regional policy discourse by offering empirical insights and evidence-based recommendations to strengthen economic resilience in Southeast Asia.

Antenatal Care (ANC) is an essential component of maternal health services that plays a vital role in maintaining the health of the mother and fetus during pregnancy and delivery. In Indonesia, coverage of ANC services K1 has reached 100%, but coverage of K4 has only reached 78% and has not met the national target. A case study in Sidenreng Rappang Regency showed better results with K1 coverage of 98% and K4 reaching 97%, although there is still room for improvement. This quantitative study with a cross-sectional design aims to analyze the relationship between maternal knowledge, attitudes, and husband's support factors on the utilization of ANC services at the Compong Village Health Post. The study population included 190 mothers with toddlers registered at the Compong Village Health Post. Sampling was carried out using the Slovin formula with a 95% confidence level and a 5% margin of error, resulting in 127 respondents as the research sample. The data collection method was carried out through a structured questionnaire containing questions about respondent characteristics, level of knowledge, attitudes towards ANC, and level of husband's support. Data analysis used the Chi-Square statistical test with a significance level of p<0.05 to determine the relationship between the independent and dependent variables. The results revealed several important findings. First, there was a significant relationship (p=0.002) between maternal knowledge and utilization of ANC services. Second, maternal attitudes also showed a significant relationship (p=0.001) with the frequency of ANC visits. Third, husband's support was shown to have a significant influence (p=0.003) on maternal participation in ANC programs. These findings confirm the multifactorial role in determining ANC service utilization. Practical implications of this study include recommendations for improving health education programs that not only target pregnant women but also actively involve husbands.

Promiscuity is a common issue among adolescents, as a transitional phase that is highly susceptible to environmental influences, directly impacting physical, mental, and social health.

Data was collected through the WHOQol-Bref survey instrument. The data analysis in this study applied the kendal test and the Chi-Square  test to test the relationship between the variables studied. After the research was carried out, a result was obtained that showed demographic factors, namely the age factor to the quality of life had a relationship and as seen from the kendal test with a value of Sig. 0.003 which was below 0.05), other demographic factors there were gender factors that had a relationship with quality of life which was shown through the chi-square test where  the Continuity Correction value sig = 0.022 < 0.05), In addition to demographic factors of age and gender, there are also demographic factors that have a relationship with quality of life, namely the work factor shown in the Chi-square  Test with a value of Continuity Correction sig = 0.008 < 0.05), and there are demographic factors, namely education factors and marital status factors that are not related to the quality of life of people with sugar level disease or diabetes mellitus. For the education factor shown in the kendal test where the sig value = 0.871 > 0.05), and marital status is shown in the Chi-square test based on the Pearson Chi-Square Sig value = 0.594 > 0.05), there are also demographic factors that have a relationship with quality of life, namely the long-suffering factor shown by the Chisquare test with the Pearson Chi-Square Sig value = 0.014 < 0.05). To break the chain of diabetes mellitus, actions are carried out for health workers to be able to anticipate, including periodic socialization to the community about the dangers of diabetes mellitus so that it can help people improve their quality of life by maintaining a healthy diet.

This study explores the meaning and role of the Nahunan tradition in maternal and infant care among the Dayak Ngaju community. A descriptive qualitative method was employed, utilizing literature review and field interviews. The findings reveal that Nahunan is not merely a naming ritual, but also symbolizes spiritual protection and social acceptance of the child. The practice involves traditional leaders, herbal remedies, and natural symbols. However, modern influences have diminished the younger generation’s understanding of its values. Preserving local culture within healthcare services is essential to maintaining community identity.

This study aims to examine diabetes mellitus from an Islamic spiritual perspective, as well as how the concept of a harmonious family and the teachings of the Qur'an can be implemented as part of healing and prevention efforts. This study uses a qualitative method based on libraries by examining primary and secondary sources in the form of the Qur'an, hadith, health literature, and the thoughts of scholars. The results of the study indicate that diabetes mellitus is a metabolic disorder characterized by increased blood glucose levels due to insulin disorders. From an Islamic perspective, one of the causes of this disease is excessive stress, an unbalanced diet, and a lack of self-control, all of which are forms of the physical and spiritual world. The Qur'an provides a solution through a spiritual approach such as dhikr, fasting, and honey consumption. In the context of Islamic law, maintaining health is part of maqāṣid al-syarī‘ah, especially in maintaining the soul (ḥifẓ al-nafs) and maintaining religion (ḥifẓ al-dīn), because a healthy body is needed to carry out worship perfectly. Therefore, efforts to cure and prevent diabetes through a spiritual approach are not only medical and psychological, but also a sharia obligation that has worship value. This study confirms that a holistic approach between medical, spiritual, and Islamic law can provide a positive contribution in dealing with chronic diseases such as diabetes mellitus.

Slum areas in Pekanbaru City are being addressed by the local government, including the Meranti Pandak Sub-district. This study aims to assess the effectiveness of the Meranti Pandak Sub-district government in maintaining environmental cleanliness in slum areas and to identify the inhibiting factors affecting its effectiveness (Case Study: Slum Area in Meranti Pandak Sub-district, Pekanbaru City). Environmental issues in this area are of major concern due to their impact on public health and quality of life. The study applies Duncan’s theory (as cited in Nurmalasari & Supriyadi, 2021), which highlights three indicators: goal achievement, integration, and adaptation. Data collection methods include observation, interviews, and documentation. The findings reveal that the sub-district government's efforts have not been fully effective. This is evident from poorly targeted programs, unequal service distribution among residents, low community participation, and weak monitoring and evaluation by the local authorities. Additional obstacles include unresolved waste management issues, limited budget, and non-permanent building structures. To improve effectiveness, the study recommends more focused program planning, sustainable community empowerment, and enhanced cross-sectoral coordination.
