Private vehicles are a frequently used mode of transportation because they are considered more practical. However, using private vehicles carries several risks, such as traffic accidents due to drivers losing focus on the road due to other activities, such as making calls on smartphones, drinking, or operating the radio. Approximately 90% of accidents are caused by human error. Convolutional Neural Network (CNN) is a type of neural network commonly used on image data. CNN is often used for image classification due to its high performance and accuracy. Therefore, this study aims to analyze the performance of CNN for the classification of distracted driving activities. The results show that the CNN model is able to effectively classify images of distracted driving activities, with an accuracy of approximately 99% across all datasets and across all input image size variations. Furthermore, the results of this study also show that differences in right-hand and left-hand drive datasets do not significantly affect model accuracy. Variations in input image size also do not significantly affect model accuracy, but do affect the training duration.

BPJS Health has incurred losses exceeding 200 billion rupiah over a two-year period due to the payment of contributions that were discontinued by participants who had utilized maternity services. Data show that 64.7% of mothers registered as BPJS Health participants only one month prior to childbirth, after which 43% either withdrew their membership or failed to continue paying contributions following delivery. The highest proportion of this behavior was observed among independent participants or non-wage recipients (PBPU). In Jambi Province, the highest level of contribution non-compliance occurs in Jambi City. In 2023, there were 77,489 participants with contribution arrears, resulting in financial losses amounting to 60.1 billion rupiah. Contribution non-compliance is influenced by various factors. This study aims to analyze the factors contributing to non-compliance among independent participants in paying BPJS Health contributions after utilizing childbirth services in Jambi City. The findings revealed that 33.3% of independent participants were non-compliant in paying BPJS Health contributions after using maternity services. Significant associations were found between contribution non-compliance and the number of family members (p = 0.001), level of knowledge (p = 0.000), illness perception (p = 0.001), clinical assessment (p = 0.000), and willingness to pay (WTP). Based on these findings, it is recommended that BPJS Health consider implementing a waiting period policy for participants intending to utilize maternity services. In addition, the Jambi City Government should strengthen promotive efforts to educate the public and raise awareness of the importance of health insurance in safeguarding household financial security.

Discomfort during pregnancy is a common experience resulting from physical, physiological, and psychological changes, yet it is often not well understood by pregnant women. Limited knowledge about normal bodily changes and pregnancy-related discomfort can reduce maternal comfort and increase anxiety. Counseling serves as an important educational strategy to improve pregnant women’s understanding, particularly within antenatal care services at primary health care facilities. This study aimed to examine the effect of counseling on pregnancy discomfort in improving mothers’ knowledge about changes during pregnancy. A quasi-experimental design with a one-group pretest–posttest approach was employed. The sample consisted of 50 pregnant women selected using a total sampling technique. Mothers’ knowledge levels were assessed before and after the counseling intervention using a structured questionnaire. Data analysis included univariate analysis to describe the distribution of knowledge levels and bivariate analysis using the Wilcoxon Signed Rank Test to evaluate differences before and after the intervention. The findings demonstrated a notable increase in knowledge following counseling, indicated by a shift from predominantly poor and moderate knowledge levels in the pretest to good knowledge in the posttest. Statistical analysis revealed a significant difference between pretest and posttest results (p < 0.05). In conclusion, counseling significantly improves pregnant women’s knowledge regarding pregnancy-related changes and discomfort.

An employment relationship is a relationship between a worker and an employer or entrepreneur involving work, wages, and orders. One outcome of this employment relationship is termination of employment. To create a just and prosperous society based on Pancasila and the 1945 Constitution, the government has enacted laws concerning termination of employment, such as Law No. 13 of 2003 concerning Manpower, Law No. 11 of 2020 concerning Job Creation, and Government Regulation No. 35 of 2021 concerning Fixed-Term Employment Agreements, Outsourcing, Working and Rest Hours, and Termination of Employment. This research uses a normative legal method, namely examining the law as it exists or should exist, or the law in books. The research was conducted by analyzing applicable laws and regulations, using library materials or secondary data covering primary, secondary, and tertiary law. Termination of employment is the right of both parties, namely workers and employers. Both parties can terminate the employment relationship according to their respective situations or conditions. This issue often generates debate because each party has different perspectives and arguments regarding termination of employment. As a result, the amount of compensation workers receive in practice also varies. Comparing Law No. 13 of 2003, Law No. 11 of 2020, and Government Regulation No. 35 of 2021 concerning termination of employment, it is clear that the Employee Rights Act No. 13 of 2003 provides more compensation than the Job Creation Law. Therefore, in practice, many companies, including PT Kuoni Indonesia, seek ways to reduce their compensation obligations under the pretext of negotiating with employees.

The active phase of labor is a crucial stage that determines the progress and success of the delivery process. Prolonged labor during this phase can increase the risk of maternal complications and reduce the comfort of the laboring mother. Various non-pharmacological interventions have been developed to support the physiological progress of labor, including acupressure at the SP6 point and oxytocin massage. This study aims to analyze the differences in the effects of SP6 acupressure and oxytocin massage on the duration of the active phase of labor at the Galala Health Center in the Tidore Islands. This study used a quasi-experimental design with a comparative approach in two intervention groups. The sample consisted of 40 mothers in the first stage of active labor who met the inclusion criteria, with 20 respondents in the SP6 acupressure group and 20 respondents in the oxytocin massage group. The duration of the first stage of labor was calculated from 4 cm cervical dilation to complete 10 cm dilation and recorded using a partograph. Data were analyzed univariately to describe the distribution of labor duration and bivariately using the Mann–Whitney U test to assess the difference between the two groups. The results showed that the median duration of the first stage of labor in the SP6 acupressure group was shorter than in the oxytocin massage group. The Mann–Whitney test showed a statistically significant difference between the two intervention groups (p < 0.05). The conclusion of this study indicates that SP6 acupressure is more effective than oxytocin massage in shortening the duration of the first stage of active labor. These findings support the use of SP6 acupressure as a safe and effective nonpharmacological intervention in intrapartum midwifery care in primary health care facilities.

Breast milk production during the postpartum period is a crucial factor in successful breastfeeding and achieving exclusive breastfeeding. However, during the early postpartum period, many postpartum mothers experience difficulties in breast milk production, influenced by physical and psychological conditions. One non-pharmacological intervention that can be used to help facilitate breast milk production is oxytocin massage, which aims to stimulate the release of the hormone oxytocin and increase the let-down reflex. This study aims to analyze the effect of oxytocin massage on breast milk production in postpartum mothers at the Marisa Community Health Center. This study used a quantitative pre-experimental design with a one-group pretest–posttest approach. The study sample consisted of 30 postpartum mothers selected using purposive sampling according to the inclusion criteria. Breast milk production was measured before and after the oxytocin massage intervention using a structured observation sheet with units of milliliters (ml). Data analysis was performed using univariate and bivariate methods. Normality was tested using the Shapiro–Wilk test, while differences were tested using the Wilcoxon signed-rank test. The results showed that the average milk output before oxytocin massage was 18.00 ± 5.95 ml, and increased to 51.83 ± 10.94 ml after the intervention. The Wilcoxon test showed a p-value of 0.000 (p < 0.05), indicating a significant effect of oxytocin massage on increasing breast milk output. It was concluded that oxytocin massage is effective as a non-pharmacological intervention to increase breast milk production in postpartum mothers and can be integrated into postpartum care in primary health care services.

The maternal mortality rate in Indonesia remains high, reaching 305 per 100,000 live births in 2021, with one contributing factor being the lack of maternal knowledge regarding pregnancy danger signs. Prenatal classes are considered a strategic intervention to improve pregnant women’s understanding of critical warning signs such as bleeding, severe abdominal pain, and infection symptoms. This study aims to analyze the influence of pregnancy classes on pregnant women’s knowledge of danger signs. The research employed a quantitative design with a cross-sectional approach involving 30 pregnant women selected through purposive sampling at several community health centers. Data were collected using validated and reliable questionnaires, with measurements conducted before (pre-test) and after (post-test) participants attended at least three prenatal classes. Data analysis used descriptive statistics and the Wilcoxon Signed Rank Test with SPSS. The results showed that most respondents were aged 20–35 years (63.3%), had a high school education (36.7%), were housewives (60.0%), and multigravida (56.7%). Before the intervention, 50% had poor knowledge and only 20% had good knowledge. After attending prenatal classes, 63.3% achieved good knowledge, while only 10% remained in the poor category. The Wilcoxon test showed a significant difference (p = 0.000). Thus, prenatal classes effectively improve knowledge and support early detection of complications, potentially reducing maternal and infant mortality rates.

This study applies the Mean Variance model, which aims to form an optimal portfolio composition in the health, property, and cyclical consumer sectors and combine the three sectors into one portfolio, then visualize its efficient frontier. This study analyzes the return profiles and compares the risks of each portfolio using alternative risk measures such as the Coefficient of Variation (CV), Value at Risk (VaR), and Conditional Value at Risk (CVaR). Daily closing price data for the three sectors listed on the Indonesia Stock Exchange (IDX) from March 2, 2020, to March 3, 2025, were used in this study. Stock selection was conducted using purposive sampling, followed by selecting seven stocks for optimization based on the lowest Coefficient of Variation (CV) value. Portfolio optimization analysis was conducted using the Python programming language with Visual Studio Code software. The findings of this study indicate that the combined portfolio incorporating the three sectors is the most efficient, with an expected return of 0.104%, standard deviation of 0.007, and alternative risk measures such as Coefficient of Variation (CV) 6.9328, Value at Risk (VaR) of -0.99%, and Conditional Value at Risk (CVaR) of -1.44%, which are lower than those of single-sector portfolios. Visualization of the efficient frontier curve confirms that the combined portfolio offers better results in terms of risk and return. The results of this study indicate that cross-sector diversification can significantly reduce risk and prevent significant losses.

This study analyzes the forms of risk and risk management strategies in melon farming in Brebes as an impact of climate change. A descriptive qualitative approach was applied using a case study through in-depth interviews with a farmer who has more than ten years of experience, supported by secondary data from BPS, BAPPENAS, and related literature. The findings reveal four categories of major risks: market, financial, operational, and socio-environmental. High-level risks include climate variability, yield decline, and pest attacks. Medium-level risks involve production costs, water management, and price fluctuations, while low-level risks consist of limited weather information and agricultural extension services. Current strategies are still basic, including fertilization, pesticide application, and water channel arrangement. Strengthening adaptation is needed through irrigation technology, climate-resilient varieties, marketing diversification, and improved access to information and institutional support.

The Information System registration module for the Regional Taxpayer Identification Number (NPWPD) was developed using the Laravel framework and implemented by the Taxpayer Identification Agency (BPPKAD) at Kediri City. The system was designed to digitize the NPWPD registration process, which was previously done manually. This traditional approach often led to long queues, extended processing times, and, at times, errors in data entry. The new system offers several key advantages, including an online registration form that allows taxpayers to upload required documents such as photos of ID cards, business locations, and other necessary paperwork. Data validation is performed by officers to ensure accuracy, and automatic notifications are sent to taxpayers, informing them of the status of their applications. The implementation of this system has had several positive impacts, such as significantly improving the efficiency of administrative processes, reducing the manual workload for officers, and increasing transparency and accountability in public services. Moreover, it has improved customer satisfaction by providing faster, more accurate, and more responsive services.
