Liturgical activities are the center of the Church’s faith life and serve as the primary means of fostering the faith of Catholic communities. However, many parish outstation members still require guidance regarding the order of the Eucharistic Celebration, the roles of liturgical ministers, and the enrichment of liturgical music. This community service activity was carried out at St. Christopher Delawau Outstation, Christ the King Gido Parish, on Sunday, November 9, 2025, by the Dian Mandala Choir group. The purpose of this activity was to introduce the proper order of the Eucharistic Celebration, to socialize Latin Ordinarium songs, and to build a spirit of fraternity in faith. The methods used included the Eucharistic Celebration, liturgical practice, choir training, demonstrations of liturgical duties, and fraternal interaction. The results of the activity indicated improved understanding among the faithful regarding the Eucharistic Celebration, enhanced skills in liturgical ministries (conductor, lector, psalmist, homilist), and the development of emotional closeness as fellow believers. This community service demonstrates that practice-based and dialogical approaches have a positive impact on strengthening the quality of liturgy among outstation communities.

Background: Sectio Caesarea (SC) surgery causes an incision wound in the abdomen, requiring a complex tissue healing process. Nutrition is a primary systemic factor supporting cell regeneration and new tissue formation through the intake of protein, vitamins, and minerals. However, many postpartum mothers still practice dietary restrictions due to misconceptions about the wound healing process. Objective: To determine the relationship between nutritional fulfillment and wound healing duration in post-SC patients at Prof. Dr. R.D. Kandou General Hospital, Manado. Methods:This quantitative research used an observational analytic design with a cross-sectional approach. The sample consisted of 20 postpartum mothers after SC, selected using purposive sampling technique. Research instruments included a questionnaire and an observation sheet. Data were analyzed using Fisher's Exact Test (α=0.05). Results: The majority of respondents (55%) had good nutritional fulfillment, and 60% of respondents experienced rapid wound healing. Statistical test results showed a p-value = 0.005 (p < 0.05), indicating a significant relationship between nutritional fulfillment and wound healing duration. Respondents with good nutrition had a rapid wound healing percentage of 90.9%, while respondents with poor nutrition had a slow wound healing percentage of 77.8%. Conclusion: Adequate nutritional fulfillment plays a crucial role in accelerating the wound healing process after Sectio Caesarea surgery.

Long-acting contraceptive methods (LACMs/MKJP) are effective family planning options for controlling fertility and improving maternal health. However, the utilization of LACMs among women of reproductive age remains relatively low, which may be influenced by their level of knowledge. This study aimed to examine the relationship between women’s knowledge levels and the utilization of long-acting contraceptive methods in the working area of UPT Puskesmas Basarang. A quantitative study with a cross-sectional design was conducted involving 58 women of reproductive age selected using purposive sampling. Data were collected using a structured questionnaire to assess knowledge levels and contraceptive use, and analyzed using the Kendall’s tau-b correlation test. The results showed that more than half of respondents had good knowledge of LACMs, yet only 39.7% reported using these methods. Bivariate analysis revealed a statistically significant relationship between knowledge level and LACM utilization (p = 0.012). The study concludes that knowledge is significantly associated with the use of long-acting contraceptive methods, although other factors may also influence decision-making. Strengthening education and counseling interventions is essential to improve informed contraceptive choices and increase the utilization of long-acting contraceptive methods.

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.

Preterm birth remains a significant public health concern due to its contribution to neonatal morbidity and mortality worldwide. Among the various risk factors, maternal infections—particularly sexually transmitted infections (STIs)—have been identified as preventable yet critical determinants of premature delivery. This study aimed to examine the relationship between STIs and preterm birth among mothers receiving care at Tomalou Primary Health Care Center. A cross-sectional analytical design was employed, involving 30 postpartum mothers whose medical records and antenatal care data were available. Data on STI status and birth outcomes were collected from health center records and laboratory results, while maternal demographic and obstetric characteristics were also documented. Results indicated that 40% of participants were diagnosed with STIs during pregnancy, and 33.3% experienced preterm birth. Chi-square analysis revealed a significant association between maternal STI status and preterm delivery (p = 0.003). Logistic regression demonstrated that mothers with STIs were sixteen times more likely to deliver prematurely compared to uninfected mothers (OR = 16.0; 95% CI: 2.45–104.3; p = 0.002). These findings suggest that STIs represent a substantial risk factor for preterm birth, even among mothers with adequate antenatal care attendance. Early detection, timely treatment, and comprehensive reproductive health education are recommended to reduce infection-related adverse outcomes. Strengthening STI screening and management within primary healthcare settings is essential to improve maternal and neonatal health outcomes. This study provides evidence for the importance of integrating infection prevention strategies into routine antenatal care to mitigate the risk of premature delivery.

This study analyzes the conditions of extreme overcapacity in an installed exhaust ventilation system (Qinstalled = 18.00 /minute) that serves four acid cabinet units, specifically for the storage of volatile Hazardous and Toxic Materials (B3) such as toluene and methanol in tightly sealed containers. Although high capacity ensures safety, this practice causes significant energy inefficiency and unnecessary negative pressure problems in the room. Based on engineering analysis using a conservative Air Change Rate (ACR) standard of   for liquid storage of 1.38 /minute. By applying the industry standard safety factor (FoS) of 1.5, the ideal flow rate (Qideal) that must be allocated is 2.07 . The optimization analysis concludes that the currently installed system is theoretically capable of safely and efficiently serving 8 units of volatile storage acid cabinets, with the addition of 4 new cabinets to maximize efficiency and reduce energy waste. This utilizes 92% of the total capacity while maintaining a safety factor above 1.5.

Increased production in the lubricant industry has become a significant issue because it generates production waste in the form of packaging, plastic, and paper waste as a direct consequence of manufacturing activities. Proper and systematic waste management is essential to reduce environmental impacts, comply with regulations, and support responsible and sustainable business practices. Lubricant production waste can damage the ecosystem and surrounding environment if not managed properly, so continuous innovation is needed to minimize environmental risks and reduce potential economic losses for the company. This study aims to analyze and implement effective waste management strategies using a combination of qualitative and quantitative approaches, including in-depth interviews with relevant stakeholders and analysis of secondary data obtained from company records. The waste management process begins with several waste reduction programs applied during the production stage to limit waste generation. Furthermore, the waste storage facility (TPS) available on the company’s premises, covering an area of 59 m², is capable of accommodating approximately 60% of the total waste that must be processed internally before further treatment or disposal.

The plastic recycling industry generates wastewater that poses a potential threat to aquatic environments if not managed optimally. Performance evaluation of Wastewater Treatment Plants (WWTP) is typically conducted partially by comparing outlet parameters against effluent standards, often failing to depict water quality conditions holistically. Therefore, this study employs the Water Quality Index (WQI) approach using the Canadian Council of Ministers of the Environment (CCME) method to evaluate the performance of PT X's WWTP in East Java. This research utilized secondary data from inlet and outlet wastewater quality tests over 23 months (January 2024–November 2025), covering 10 parameters. Analysis was conducted by calculating removal efficiency and determining factors F1 (scope), F2 (frequency), and F3 (amplitude) as the basis for the WQI-CCME calculation. The results indicate that the WWTP achieved high efficiency (>80%) in reducing dominant parameters such as TSS, TDS, BOD, and COD. However, violations of effluent standards were still observed in certain parameters. The obtained WQI-CCME value was 69,30, categorized as "Fair" with a moderate level of violation. These findings demonstrate that although the WWTP meets regulatory standards, the WQI-CCME approach provides a more comprehensive assessment of performance. Optimization of advanced treatment units is recommended to improve effluent quality and sustainable WWTP performance.                                                                   

The KRI Nagapasa Class is a submarine of the Indonesian Navy that has the capability to deploy sea mines, launch anti-surface missiles, and release countermeasure torpedoes. However, to face the increasingly complex dynamics of the regional strategic environment, it is necessary to increase combat power through the installation of a Sub Launch Missile weapon system. Until now, the Indonesian Navy does not have a submarine equipped with this underwater missile, especially in the Chang Bogo class. This study aims to analyze and determine the most appropriate choice of Sub Launch Missile missiles to support submarine training and operations. The method used is the Analytic Hierarchy Process (AHP) with a quantitative approach. The results of the ranking of five respondents showed that the SM-39 Exocet missile was in first place with a value of 0.46424 followed by the CM708UNB with a value of 0.41461 and the UGM-84 Harpoon with a value of 0.12115. The SM-39 Exocet missile was chosen as a priority because it has technical specifications that best meet the operational needs of the Indonesian Navy (TNI AL), as well as significantly contributing to enhancing the deterrence effect and combat capability of the Nagapasa-class submarines.

Public health is a crucial aspect of improving well-being, particularly at the village level. However, in Srigading Village, Lawang District, Malang Regency, access to information related to health services remains a significant challenge, resulting in suboptimal utilization of Posyandu and Puskesmas services. To address this issue, a web application called “Srigading Sehat” has been developed as a digital platform providing health service information through interactive maps and service schedules. This community service activity employs the IDEA approach (Identify Objective, Design Action Steps, Engage Our Plan, Assess and Follow Up) as a systematic framework. The Identify Objective stage identified limitations in health information access; Design Action Steps designed a participatory learning-based application development model; Engage Our Plan implemented application development, socialization, and training for 25 participants comprising village officials, posyandu cadres, and the general community; and Assess and Follow Up evaluated achievements through Firebase Analytics monitoring. Results showed increased health information access marked by 500 health information page visits within the first 30 days of launch, with total Firebase reads reaching 631 (+1,026.8%). Four village health facilities are actively registered and using the application to independently update their service information. This application is anticipated to serve as an appropriate technological innovation contributing to the enhancement of health services at the village level.

Labor pain is a significant challenge faced by in-partum mothers, with a prevalence of 70% in Indonesia, and 40% of women reporting severe pain (Central Statistics Agency, 2022). Conventional pharmacological methods often do not provide optimal results and can cause side effects. As a non-pharmacological alternative, oxytocin massage has shown promise in reducing labor pain intensity by stimulating the endogenous production of oxytocin, a natural analgesic hormone. This study aimed to assess the effect of oxytocin massage on labor pain intensity in in-partum mothers at Manado Medical Center Hospital. A pre-experimental design with a one-group pre-test post-test approach was used. The sample consisted of 30 in-partum mothers who met the inclusion criteria. Pain intensity was measured using the Numeric Rating Scale (NRS) before and after a 30-minute oxytocin massage administered by trained health workers. Data were analyzed using a paired t-test. The results showed a significant reduction in pain intensity from an average of 7.23 (SD=1.08) before the massage to 4.63 (SD=1.11) afterward, with a decrease of 2.6 points. The proportion of mothers experiencing severe pain decreased from 50% to 20%, while mild pain increased from 16.7% to 46.7%. The paired t-test revealed a highly significant difference with t=10.274 (df=29), p=0.000 (p<0.05). In conclusion, oxytocin massage is an effective non-pharmacological intervention that can significantly reduce labor pain and improve the birth experience. It can be incorporated into standard maternity nursing protocols to enhance maternal care.

Breastfeeding failures frequently result in issues. Lack of information about proper breastfeeding technique is one of the issues that frequently arises in nursing women, leading to uncomfortable nipples when the infant does not suck the nipple down to the areola. According to the 2022 Indonesian Demographic Health Survey, 79.3 individuals had painful nipples. The purpose of this study is to ascertain how well breastfeeding practices work in relation to the prevalence of painful nipples among nursing moms at the South Bulango Community Health Center in 2025. This kind of study employs a cross-sectional, quantitative research approach. 47 nursing women who were chosen by accidental sampling served as the study's population and sample. There is a correlation between breastfeeding practices and the incidence of sore nipples at the South Bulango Health Center in 2025, according to the results of statistical testing using the chi-square test. The p value (0.000) is not greater than α (0.05), so H0 is rejected and Ha is accepted. It is intended that the community, especially postpartum moms, would gain more understanding of the connection between breastfeeding methods and the prevalence of painful nipples in nursing moms.

Sleep disturbances are a common problem during pregnancy, often resulting from physiological changes, hormonal fluctuations, and psychological stressors. Poor sleep quality in pregnant women can lead to fatigue, mood disorders, and adverse maternal and fetal outcomes. Mindfulness-based interventions, which emphasize present-moment awareness and non-judgmental acceptance, have been suggested as an effective strategy to improve sleep quality and reduce stress. This study aimed to analyze the effect of mindfulness on sleep quality among pregnant women in the Puskesmas Tosa catchment area. A quasi-experimental design with a pretest-posttest control group was employed. A total of 30 pregnant women in their second and third trimesters participated and were divided equally into intervention and control groups. The intervention group received weekly mindfulness sessions for four weeks, including guided breathing, body scan, and focused attention meditation, while the control group received routine antenatal care. Sleep quality was assessed before and after the intervention using the Pittsburgh Sleep Quality Index (PSQI). Data were analyzed using descriptive statistics and paired and independent t-tests, with a significance level set at p<0.05. Results indicated that the intervention group experienced a significant improvement in sleep quality, with mean PSQI scores decreasing from 9.80 ± 2.10 to 5.60 ± 1.90 (p<0.001). In contrast, the control group showed no significant change (pretest 9.53 ± 2.30; posttest 9.27 ± 2.25; p=0.395). These findings demonstrate that mindfulness effectively reduces sleep disturbances among pregnant women by addressing both psychological and physiological contributors to insomnia. In conclusion, integrating mindfulness practices into routine antenatal care is a practical, low-risk, and non-pharmacological approach to enhancing maternal sleep quality, reducing stress, and promoting overall well-being during pregnancy. This study provides evidence to support the inclusion of complementary mind-body interventions in primary health care services.

This study aims to determine the cost of coffee production as a basis for setting the selling price in the Sarah Jaya coffee business. Accurate calculation of production costs is essential because it directly affects pricing decisions and the level of profit generated by the business. The full costing method is used to determine the cost of production, as this method provides a more comprehensive and detailed calculation by including all cost components required in the production process, such as raw material costs, direct labor costs, and both fixed and variable manufacturing Overhead costs. Determining the cost of production using an appropriate method can significantly influence the determination of the selling price and ensure that the business achieves sustainable profitability. The application of the full costing method is expected to provide practical benefits for Small and Medium Enterprises (MSMEs), particularly in improving financial management and decision-making accuracy. The results of this study indicate that the calculation of the cost of production for the Sarah Jaya coffee business conducted by the business owner using the full costing method aligns well with the determination of the selling price and the profit generated. This is because the full costing method takes into account more detailed and comprehensive cost elements, resulting in a more realistic and reliable calculation of production costs.

Local Revenue (PAD) refers to the income obtained by regional governments from sources within their own jurisdiction, such as taxes and local levies. One of the important components of PAD is market levies, which are collected from traders as a fee for the use of market facilities. This study aims to analyze the contribution of market levies to PAD in North Toraja Regency. The method used in this study is descriptive quantitative, utilizing secondary data from the Bapenda of North Toraja for the period of 2020–2024. The results of the study show that the contribution of market levies to PAD fluctuates with a downward trend. In 2020, the contribution was recorded at 1.17%, but by 2024, it decreased to 0.71%. This decline is attributed to several factors, including increased competition from modern markets that are more attractive to consumers, a decrease in the number of buyers visiting traditional markets, and arrears from traders, which has led to suboptimal revenue collection from levies. These findings highlight the importance of efforts by local governments to enhance the appeal of traditional markets and manage levies more effectively in order to increase their contribution to PAD in the future.

This study aims to determine the cost of production for Sa'dan woven fabric using two cost calculation methods, namely full costing and variable costing. These methods are applied to analyze the cost differences involved in the production process. Data were collected through observation and direct interviews with the weavers. Based on the research findings, the cost of production per sheet of woven fabric using the full costing method is Rp 316,800, which includes the costs of raw materials, labor, and production overheads. In contrast, the calculation using the variable costing method results in a lower production cost, amounting to Rp 314,690. Additionally, the uncertainty in the production quantity also affects the cost incurred. The higher the production quantity, the greater the cost incurred, which impacts the setting of selling prices and the desired profit by the weaver. Therefore, it is important for the weavers to consider efficiency in production planning in order to optimize costs and maximize profits. By understanding the differences between these two methods, the weavers are expected to make more accurate pricing decisions based on the current production conditions, ensuring better business sustainability.  

This study aims to describe the innovative application of the Problem Based Learning (PBL) model in improving the understanding of speech texts in grade VIII students of SMP Negeri 1 Banjarmasin. The study uses a descriptive qualitative approach supported by quantitative data in the form of student learning outcomes. Data sources include lesson planning documents (RPP), the "Understanding Speech" teaching module compiled by Istiqomah HM, and student learning outcomes. The learning process is carried out through PBL stages which include problem orientation, organizing students in group work, investigation, compiling and presenting results, and learning reflection. The results show that the application of the PBL model is able to improve students' understanding of the structure, content, and linguistic rules of speech texts. The average individual score reached 96.84 with most students obtaining a score ≥ 80. In addition to improving academic achievement, the PBL model also has a positive impact on students' critical thinking skills, collaboration, and communication skills. Although technical obstacles and differences in literacy levels were still found, this model is considered effective and worthy of further development in Indonesian language learning at the junior high school level.

This study aims to analyze the issue of online gambling in Indonesia and examine the urgency of extradition agreements as a legal instrument to prosecute online gambling operators who conduct their activities from abroad. Although gambling has been declared a criminal act under the Indonesian Criminal Code (KUHP) and the Electronic Information and Transactions Law (ITE Law), its enforcement has not been effective due to the transnational nature of this crime, in which gambling operators run their platforms from other countries, placing them beyond the direct reach of Indonesian jurisdiction. The research employs a normative legal methodology, examining statutory regulations, principles of criminal law, and relevant legal literature. The objects of study include the 1945 Constitution, the Criminal Code, and the ITE Law as the legal foundations for combating online gambling, as well as provisions concerning extradition within the framework of international cooperation. The findings indicate that although Indonesia normatively possesses legal grounds to prosecute perpetrators abroad through the principles of personality and protection, implementation remains hindered by state sovereignty and jurisdictional limits. Government efforts to block gambling websites have proven ineffective, as new sites continually emerge. Therefore, extradition agreements are essential and urgent as a solution to overcome jurisdictional barriers, enabling the transfer of offenders to Indonesia for prosecution and ensuring state protection for citizens from the harmful impacts of online gambling.
