“Hallyu” (the Korean Wave) refers to the popularity of everything originating from Korea. Aims to examine the description of students’ K-Pop celebrity worship behavior before and after receiving group counseling with the Cognitive Restructuring technique, analyze the differences in students’ behavior, and test the effect of the counseling on reducing celebrity worship tendencies. The findings are expected to provide theoretical contributions to the field of guidance and counseling, particularly regarding the application of Cognitive Restructuring to mitigate obsessive behaviors, as well as practical benefits for school counselors and institutions in helping students reduce celebrity worship tendencies so they can remain focused on academic and social development. The research employed an experimental method with a One-Group Pretest–Posttest design. The subjects consisted of eight tenth-grade students at SMK Negeri 1 Kuantan Mudik who were identified as having a high level of K-Pop celebrity worship. The instrument used was a 19-item K-Pop celebrity worship scale that had been tested for validity and reliability. Data were analyzed using the Wilcoxon test and N-Gain calculations to determine treatment effectiveness. The results showed that prior to receiving group counseling with Cognitive Restructuring techniques, most students were categorized as having high or moderate levels of celebrity worship. After the intervention, all students experienced a decrease in celebrity worship behavior, falling into the low category. This demonstrates that group counseling using Cognitive Restructuring is effective in helping students shift irrational thinking patterns toward more rational ones, enabling them to control excessive celebrity worship behavior.  

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.                                                                   

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.

Adolescent girls often complain of dysmenorrhea, or discomfort during menstruation, which can range from mild to severe and interfere with daily activities, especially learning. To prevent this disease from lowering the quality of life of adolescents, it must be treated. Education about dysmenorrhea and its treatment is one of the actions that can be taken. The study used a pre-experimental design approach, a quantitative research design, and a single-group pre-test-post-test research plan without a control group design. Using a proportional stratified random sampling approach, 57 female students of class X formed a research sample. The use of films on dysmenorrhea for health education serves as an independent variable of the study. Adolescent girls' knowledge and attitudes about dysmenorrhea function as a study-dependent variable. The validity and reliability of these instruments are checked. Univariate and bivariate analysis were used as data analysis methods in this study. The Wilcoxon Signed Rank Test is used for hypothesis testing. It was determined that health education using dysmenorrhea film had an impact on the knowledge and attitudes of adolescent girls about the treatment of dysmenorrhea based on the findings of the Wilcoxon Signed Rank Test (Asymp.) with a value of 2-tailed 0.000 (p<0.05). The findings of the study showed that among grade 10 students at SMA Negeri 13 Selatan Halamahera, health education through dysmenorrhea films had an impact on the knowledge and attitudes of adolescent girls about the treatment of dysmenorrhea.

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.

This study aims to evaluate the effectiveness of various doses of 6.25% Poly Aluminium Chloride (PAC) and 0.1% polymer flocculant in reducing Total Suspended Solids (TSS) and assessing pH changes in coal stockpile wastewater at PT PLN Nusantara Power UP Paiton Unit 9. Stockpile wastewater typically contains high levels of suspended solids originating from water spray activities that carry fine coal particles. The coagulation–flocculation process was performed using the jar test method with PAC dosages of 35 ppm, 50 ppm, and 65 ppm, along with flocculant dosages of 6 ppm and 7 ppm. pH and TSS were analyzed before and after treatment to assess process effectiveness. The results indicate that a PAC dosage of 35 ppm combined with a 6 ppm flocculant achieved the highest TSS removal efficiency of 98.15%. Increasing PAC dosage resulted in reduced performance due to overdosing effects, leading to charge destabilization and impaired floc formation. These findings highlight the importance of optimizing coagulant dosage to improve stockpile wastewater quality for safe reuse in operational activities.

Anxiety is a common psychological response experienced by contraceptive users, particularly among implant acceptors. Feelings of anxiety may arise due to hormonal changes, fear of side effects, and unpleasant experiences during contraceptive insertion. Aromatherapy using lavender essential oil has been shown to produce a calming effect through the activation of the limbic system and regulation of neurotransmitters, making it a potential method for reducing anxiety. This study aimed to determine the effect of lavender essential oil therapy on reducing anxiety among contraceptive implant acceptors at Tiley Health Center. A quasi-experimental design with a pretest-posttest control group approach was employed. A total of 30 respondents were randomly divided into treatment and control groups. The treatment group received inhalation of lavender essential oil for 10 minutes daily over three consecutive days, while the control group received no intervention. Anxiety levels were measured using the Hamilton Anxiety Rating Scale (HARS). The results indicated a significant reduction in anxiety scores in the treatment group before and after the intervention (p < 0.001), while the control group showed no meaningful difference (p > 0.05). These findings demonstrate that lavender essential oil aromatherapy is effective in reducing anxiety among implant contraceptive acceptors. This non-pharmacological therapy can be recommended as an easy, affordable, and safe complementary intervention in midwifery care services.

Malang Regency is known as a strategic location with considerable potential as a tourism destination in Indonesia. According to data released by the Central Bureau of Statistics, Malang Regency has recorded 267 tourist destinations spread across 33 districts. This study uses data from one water tourism destination, referred to as Tourism Site X, which focuses on the management and development of recreational areas, including swimming pools, bathing facilities, water attractions, artificial lakes, as well as the management of recreational parks and family facilities such as playgrounds, seating areas, and recreational and educational facilities. Tourism Site X is located in Pakis District, Malang Regency. The reuse of treated wastewater as a non-potable water source for irrigating green open spaces represents a crucial strategic approach to conserving water resources, particularly in water tourism areas such as Tourism Site X, which require substantial water supplies. In practice, the wastewater generated in Tourism Site X mainly originates from domestic sources, including activities such as cleaning swimming pool areas and animal enclosures, toilet usage, and food court operations. This study aims to assess whether the quality of treated wastewater from the wastewater treatment process at Tourism Site X complies with the required standards for green open space irrigation, in accordance with the Regulation of the Minister of Environment/Environmental Control Agency of the Republic of Indonesia Number 11 of 2025 concerning Wastewater Quality Standards and Wastewater Treatment Technologies for Domestic Wastewater, as well as to identify parameters that need to be reduced or eliminated.

The danger of cadmium contamination in water sources remains a crucial environmental issue due to its persistent nature and high toxicity level, which poses serious risks to human health and ecosystems. Cadmium is a non-biodegradable heavy metal that can accumulate in living organisms over time. The presence of these toxic Cd²⁺ ions is known to trigger damage to vital organs such as the liver and kidneys; therefore, reducing their concentration in aquatic environments is of paramount importance for environmental protection and public health safety. Among various treatment methods, adsorption is considered one of the most effective and economical techniques for removing heavy metal ions from contaminated water. In this study, the capability of mesoporous silica MCM-48-NH₂ as an adsorbent for Cd²⁺ ions was systematically evaluated. The adsorption performance was examined by investigating several important parameters, including contact time, solution acidity level (pH), and initial Cd²⁺ concentration. Furthermore, the adsorption mechanism and interaction between Cd²⁺ ions and the adsorbent surface were analyzed using Langmuir and Freundlich isotherm models. The results demonstrate that the adsorption process of Cd²⁺ ions onto MCM-48-NH₂ tends to follow the Langmuir isotherm model, indicating monolayer adsorption behavior, with a maximum adsorption capacity of 0.66 mmol g⁻¹.

The discharge of surfactant-laden wastewater from the rapidly expanding laundry industry poses significant environmental risks, especially in densely populated urban areas. While constructed wetlands (CWs) and Eco-Enzyme technology have shown promise for surfactant remediation, their standalone application requires long hydraulic retention times (HRTs), limiting practical implementation. This study evaluated the efficacy of a novel integrated system combining a subsurface constructed wetland (SSFCW) with fruit peel-derived Eco-Enzyme to treat synthetic laundry wastewater. Over a 6-day treatment period, the combined system achieved a remarkable surfactant removal efficiency of 99.63%, reducing the concentration from 225 mg/L to 0.835 mg/L—well below the regulatory threshold of 3 mg/L. The synergistic degradation mechanism involves enzymatic hydrolysis via Eco-Enzyme lipase and protease activity, complemented by microbial mineralization in the wetland rhizosphere. This system maintains optimal environmental conditions, with a stable pH of 6.85-7.32 and a temperature of 30.9-35.2°C, supporting robust biological activity. These findings demonstrate that the integrated Eco-Enzyme/SSFCW system overcomes the limitations of conventional HRT approaches, offering a highly efficient, sustainable, and practical decentralized wastewater treatment solution for the laundry industry.  

Pain is a prevalent issue frequently seen by pregnant women in their third trimester, attributable to physiological, biomechanical, and psychological alterations during gestation. Non-pharmacological pain management is essential as a secure alternative to enhance the comfort of pregnant women. Perinatal Yoga and Relaxation Techniques are two commonly endorsed non-pharmacological therapies; yet, comparative analyses of their efficacy remain scarce, particularly within primary health care settings. This study is to evaluate the efficacy of Perinatal Yoga against Relaxation Techniques in alleviating pain among pregnant women in their third trimester at the Bongo II Community Health Centre. The research employed a quasi-experimental design with a two-group pretest-posttest methodology. The sample comprised 38 pregnant women in their third trimester, categorized into two groups: 19 participants in the Perinatal Yoga group and 19 participants in the Relaxation Techniques group. The Numeric Rating Scale (NRS) was utilized to assess pain severity prior to and following the intervention. A paired t-test was utilized for intra-group differences, whereas an independent t-test was employed to assess inter-group efficacy.The findings indicated that both Perinatal Yoga and Relaxation Techniques markedly diminished pain intensity in pregnant women throughout their third trimester (p<0.001). The decrease in pain in the Perinatal Yoga group was statistically significant compared to the Relaxation Technique group (p<0.05). This study concludes that Perinatal Yoga is superior than Relaxation Techniques in alleviating pain in pregnant women during their third trimester. Perinatal Yoga is indicated as an effective and practical non-pharmacological technique in antenatal treatment inside primary health facilities.

Dysmenorrhea, which is common in adolescent girls, is a painful menstrual cycle that frequently interferes with daily activities, both in the classroom and in social situations. Dysmenorrhea is a common condition that needs particular care as a reproductive health concern, notably among young people. Both pharmacological and non-pharmacological approaches can be used to treat dysmenorrhea. The use of warm water compresses is a simple, inexpensive, and effective non-pharmacological approach. By increasing blood vessel dilatation, enhancing blood circulation, lowering muscular tension, and lowering pain perceptions, warm water compresses aid in alleviating dysmenorrhea symptoms. The objective of this study is to assess the impact of warm compresses on the severity of dysmenorrhea pain scales in teenage girls at the Buntalo Community Health Center. The design of this trial was pre-experimental, using a one-group pretest-posttest technique. Using a purposive sampling method, a sample of 20 respondents was chosen. The Wilcoxon test was used to conduct the data analysis. According to the data, there was a statistically significant reduction in pain intensity, with a Z value of -4.065 and a p-value of 0.000 (p < 0.05). The average pain scale decreased from 2.95 to 1.80. Based on these findings, it is reasonable to conclude that warm water compresses are helpful in alleviating dysmenorrhea pain in young women. One of the suggestions for non-pharmacological treatments to help alleviate dysmenorrhea symptoms in adolescents is anticipated to be the outcome of this research.

This study aims to analyze the process of processing fruit peel waste from juice traders into eco-enzymes as an effort to reduce environmental pollution. The research uses qualitative descriptive methods through direct observation, documentation, and literature studies. Fruit peel waste is fermented at a ratio of 1:3:10 (molasses : fruit waste : water) for three months under anaerobic conditions. The fermentation results show good eco-enzyme characteristics, characterized by a pH of 3, a fresh sour aroma, and a brownish color as an indicator of fermentation success. These findings show that the process of processing eco-enzymes from fruit peel waste can be done simply, cheaply, and environmentally friendly. In addition, the use of eco-enzymes has the potential to reduce the volume of organic waste disposed of in landfills and reduce water and soil pollution. The resulting eco-enzyme also has potential applications as natural cleaners, liquid fertilizers, and odor controllers. Thus, the treatment of fruit peel waste not only supports sustainable environmental management practices, but also encourages the implementation of the circular economy as well as community empowerment ecologically and economically.

Nausea and vomiting are common symptoms experienced during early pregnancy, especially in the first trimester, and can adversely affect maternal comfort, nutritional intake, and overall well-being. In primary health care settings, these symptoms are often managed with pharmacological treatments; however, such approaches may raise concerns regarding safety, potential side effects, and accessibility for pregnant women. Therefore, there is increasing interest in non-pharmacological interventions that are safer and more practical. One alternative method is lemon aromatherapy (Citrus limon), which is believed to reduce nausea and vomiting by stimulating the olfactory system and promoting a relaxing effect. This study aimed to assess the effectiveness of lemon aromatherapy in decreasing the frequency of nausea and vomiting among first-trimester pregnant women diagnosed with emesis gravidarum at the Rum Balibunga Community Health Center. The research applied a pre-experimental design using a one-group pretest–posttest approach. A total of 30 pregnant women in their first trimester were selected through purposive sampling. The intervention involved inhalation of lemon aromatherapy over a specified duration. Data on the frequency of nausea and vomiting were collected before and after the intervention using a structured observation instrument. The data were analyzed using both descriptive and inferential statistics, with the Wilcoxon signed-rank test employed to determine differences between pre- and post-intervention results. The findings revealed a significant reduction in nausea and vomiting frequency after the intervention. Overall, lemon aromatherapy proved to be an effective, safe, and practical non-pharmacological option to support antenatal care services.

Depression is one of the mental health problems that often arise in patients with chronic diseases, such as diabetes mellitus, hypertension, and chronic kidney failure. This condition not only impacts the patient's quality of life, but also affects the treatment process and the burden on the family. However, mental health literacy in the community is still low, so targeted preventive and curative efforts are needed. The Community Service Program (PKM) aims to improve people's mental health through educational interventions with scientific booklet media that are easy to understand and apply. The activity method is carried out in a participatory manner, including the preparation stage, socialization, educational implementation, and evaluation. Education is provided to the community with a focus on preventing depression through a healthy lifestyle, stress management skills, and early intervention efforts by seeking professional support. Evaluation is carried out through pre-post tests, observations, and group discussions. The results of the activity showed an increase in public knowledge about depression, a change in attitudes to be more open in expressing feelings, as well as practical skills in relaxation, maintaining sleep patterns, and building social support. Participants also better understand the importance of seeking professional help when depressive symptoms are getting worse. The conclusion of this PKM is that the scientific booklet has proven to be effective as a preventive and curative educational intervention medium, and can be an innovative strategy in improving the mental health of people affected by chronic diseases.

ABSTRACT Background: Pregnancy complications are one of the causes of morbidity and mortality in women. Data from the 2017 Indonesian Demographic and Health Survey (SDKI) showed that 28% of pregnant women in Indonesia are at risk of experiencing complications during pregnancy. Preeclampsia is a condition characterized by the onset of hypertension followed by organ dysfunction either with or without proteinuria at a gestational age above 20 weeks. Objective: The purpose of this study was to determine the characteristics and outcomes of neonates born to mothers with preeclampsia. Method: This type of research is a quantitative descriptive study using secondary data and using a total sampling of 261 medical records. Results: The results of the study were as follows: preeclampsia occurs mostly in young adults 73.95%, Primigravida 60.15%, Islam 50.50%, working mothers 62.45%, secondary education 80.07%, and first marital status 76.62%. The description of neonatal outcomes in mothers giving birth with preeclampsia was obtained with neonatal outcomes in good condition, namely 47.14% born at term gestational age with 43.67% non-LBW conditions, experiencing asphyxia 37.94% and being treated without respiratory support 65.52%. Conclusion: the outcomes of neonates born to mothers with preeclampsia quite often experience asphyxia. Early detection, prevention and treatment of complications, especially in cases of preeclampsia, are necessary so that neonatal outcomes can be maintained without complications and produce a good level of health for both mothers giving birth and newborns.

Global data shows that more than 60% of adolescents report experiencing moderate to severe stress due to academic and social demands. Physical activity plays an important role in maintaining adolescent mental health. Regular physical activity can stimulate the release of endorphins, improve cognitive function, reduce muscle tension, and reduce levels of cortisol, the main hormone associated with stress. One of the easiest, cheapest, safest, and most accessible forms of physical activity is walking. Walking is a moderate-intensity aerobic activity that has been proven to improve mood, improve sleep patterns, and reduce anxiety. The purpose of this study was to determine the effectiveness of walking as a physical activity on stress disorders in adolescents. The research method used a quasi-experimental design with a pretest-posttest control group approach, involving 44 participants, comprising 22 intervention and 22 control subjects. The walking activity was conducted for three consecutive days, with a duration of 60 minutes, from 16:00 to 17:00 WIB, on 16-18 December 2024. The sample criteria were first-year nursing students in their first semester who performed walking activities continuously for three days. The results showed a significant difference in stress levels before and after the intervention, with a significance level of (Z=-3.557, p=0.000). This means that there was a significant difference in stress levels between before and after the physical activity intervention. The difference in stress levels before and after the intervention in the control group was significant (Z=-1.000, p=0.317). This means that there was no difference in stress levels in the control group. The difference in stress levels between the intervention group and the control group after treatment was significant (Z=-3.445, p=0.001). This indicates that there is a significant difference in stress levels between the intervention group and the control group after the physical activity intervention. Walking is an effective, affordable, and feasible intervention for the adolescent population as a promotive and preventive strategy in stress management.

Soil contamination by hydrocarbons, pesticides, heavy metals, and complex pollutants is rapidly increasing and degrading essential ecosystem functions. Physical or chemical treatments offer faster results, yet they are often costly, energy-intensive, and risk disrupting soil biological integrity without fully eliminating pollution sources. Microorganism-based bioremediation provides a more sustainable alternative by utilizing microbial metabolism to degrade or immobilize pollutants into less toxic and less mobile forms. This article presents a structured literature review on the roles and applications of microorganisms for bioremediation of contaminated soils, covering comparisons between single isolates and microbial consortia, dominant biological mechanisms, and ecological challenges in field application. A Systematic Literature Review approach was applied, using narrative synthesis and thematic clustering of national and international journals published between 2020 and 2025. The review indicates that single microbial isolates are commonly selected for specific pollutant targets, whereas microbial consortia are preferred for mixed or persistent contaminants due to metabolic synergy that enhances microbial adaptability and stepwise pollutant breakdown in highly polluted soils. Adaptive mechanisms such as EPS production and biofilm formation contribute to microbial resilience under stress and help retain contaminants within the soil matrix. Key challenges identified include inoculum stability under extreme conditions and limited microbial access to pollutants trapped in micro-soil pores. The findings highlight that microbial selection strategies must be tailored to pollutant characteristics and soil environmental conditions, while also emphasizing the potential of biofilm-based systems and organic carriers to support broader field implementation of microbial bioremediation.
