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.

Low student achievement in mathematics, particularly in arithmetic sequences and series, has led to decreased learning motivation and participation. Therefore, innovative and engaging instructional strategies are required, one of which is the implementation of ice-breaking activities to reduce boredom and enhance students’ learning engagement. This study aimed to examine the effect of implementing ice breaking on the mathematics learning outcomes of tenth-grade students at SMK Kesehatan Samarinda in the topic of arithmetic sequences and series. This research employed an experimental method using a quasi-experimental design, involving two groups: an experimental group that received instruction incorporating ice breaking and a control group that did not receive such treatment. The total sample consisted of 60 students selected through purposive sampling. The research instrument was a learning achievement test administered as a pretest and posttest. Data were analyzed using a paired sample t-test to determine differences in learning outcomes between the two groups. The results revealed a significance value of 0.000 (< 0.05), indicating a significant difference in learning outcomes between the experimental and control groups. Therefore, it can be concluded that the implementation of ice breaking has a significant effect on improving students’ mathematics learning outcomes. This strategy creates a more active, interactive, and enjoyable learning environment, thereby facilitating students’ understanding of mathematical concepts, particularly arithmetic sequences and series.

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.

“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 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.  

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.

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.                                                                   

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.

ABSTRACT Background: Imminent Premature Delivery (PPI) is a situation where there is a threat to pregnancy caused by regular uterine contractions accompanied by cervical changes at a gestational age of less than 37 weeks. In Indonesia, based on the 2018 Basic Health Research, the prevalence of premature birth reached 29.5% of 1000 live births. At Ngoerah Hospital, Denpasar, the incidence of PPI from 2020 - 2024 based on data reached 642 out of 4,196 (15.30%) total deliveries. Objective: The aim of this study was to determine the incidence of Imminent Premature Parturition at Ngoerah Hospital, Denpasar, from 2020 to 2024.

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.

Hypertension is a major public health problem with an increasing prevalence and is often undetected due to its asymptomatic nature, leading to serious complications if not properly controlled. Low levels of public knowledge and poor adherence to preventive behaviors, routine health checks, and treatment remain significant challenges in hypertension management at the community level. This community service program aimed to improve public knowledge and awareness of hypertension through the implementation of the CERDIK and PATUH approaches. The program employed a community-based promotive and preventive method, including health education, blood pressure screening, and interactive discussion and counseling. The activity was conducted in RW 013, Kapuk Subdistrict, Cengkareng District, involving 60 adult and elderly participants. Knowledge levels were assessed using pre-test and post-test questionnaires and analyzed descriptively. The results demonstrated a substantial improvement in participants’ knowledge after the health education intervention, with the mean knowledge score increasing from 35 before the intervention to 80 after the intervention. In addition, the variation in knowledge levels among participants became more homogeneous following the educational activities. High community enthusiasm and active participation during the program reflected positive acceptance and engagement with the hypertension education initiative. This community service activity confirms that community-based health education using the CERDIK and PATUH approaches is effective as a promotive and preventive strategy to enhance public knowledge of hypertension. Improved knowledge is expected to encourage healthier lifestyle behaviors and greater adherence to hypertension control practices, thereby supporting sustainable and independent blood pressure management within the community.

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.

Tuberculosis (TB) remains one of the leading infectious diseases causing morbidity and mortality in Indonesia. Limited public health literacy regarding TB symptoms, prevention, and treatment adherence contributes to delayed diagnosis and poor treatment outcomes. This community service program aimed to improve public understanding and awareness of TB through interactive educational activities conducted at the Outpatient Unit and TB Clinic of UPT Puskesmas DTP Saketi, Pandeglang Regency. The activities involved 30 participants, including TB patients and their families. Interactive counseling sessions, audiovisual media presentations, and group discussions were used to engage participants actively. Evaluation results showed a 35% increase in participants’ knowledge scores, greater awareness of the importance of completing treatment, and improved communication between patients and healthcare workers. The implementation of interactive education proved effective in enhancing TB health literacy and supporting national TB elimination efforts at the primary healthcare level.

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.

Sweet corn is a horticultural commodity that is widely consumed in Indonesia. This study evaluated the effectiveness of NPK 18-18-18 fertilizer on the vegetative growth, yield components, and relative agronomic effectiveness (RAE) of sweet corn (Zea mays saccharata). Field experiments were conducted using fertilizer dosages of 0,50, 0,75, 1,00, and 1,50 NPK, with a control treatment for comparison. The application of NPK 18-18-18 significantly increased plant height, stem diameter, leaf number, ear length, ear diameter, biomass weight, ear weight with husk, ear weight without husk, plot yield, and overall productivity compared with the control. Mean values across treatments ranged from 68,94–205,72 cm for plant height, 7,41–20,47 mm for stem diameter, 6,01–13,00 leaves per plant, 15,41–20,89 cm for ear length, and 36,05–49,65 mm for ear diameter. Biomass weight ranged from 0,12–0,34 kg, ear weight with husk from 0,13–0,34 kg, and ear weight without husk from 0,12–0,28 kg. Plot yield varied between 7,91–25,46 kg, corresponding to productivity levels of 5,02–16,16 t/ha. RAE analysis indicated that fertilizer application was effective at dosages of 0,75, 1,00, and 1,50 NPK, with the highest effectiveness observed at 1,50 NPK (118%). Notably, the 0,75 NPK dosage achieved an RAE value of 101%, demonstrating that lower fertilizer input can enhance yield while reducing production costs and mitigating fertilizer scarcity. These findings suggest that NPK 18-18-18 fertilizer, when applied at an optimal dosage, can be effectively utilized in sweet corn cultivation to improve growth and productivity while ensuring efficient nutrient management.

Diabetic nephropathy is a chronic complication resulting from hyperglycemia, which triggers oxidative stress and inflammation, leading to progressive structural and functional kidney damage. Orange peel and Aloe vera contain bioactive compounds with antioxidant and antifibrotic properties that may protect the kidneys from diabetes induced injury. Nanoemulsion delivery systems can enhance the bioavailability of these extracts in the body. This experimental study aimed to analyze the nephroprotective effects of orange peel and Aloe vera nanoemulsion in a diabetic nephropathy rat model, including glomerular morphology and kidney function. A post-test only control group design was used on Wistar rats divided into five groups: positive control, negative control, and three treatment groups receiving varying nanoemulsion doses. Glomerular structure was evaluated by assessing the number of glomeruli exhibiting synechiae and analyzed using the Kruskal–Wallis test due to non-normal data distribution, yielding p=0.2387 (p>0.05), indicating no significant differences among groups. Urea levels were elevated above normal, whereas creatinine levels remained within normal limits. Although not statistically significant, the treatment groups demonstrated nephroprotective tendencies, shown by improvements in glomerular synechiae in the diabetic nephropathy model.

As a high-value crop, potatoes necessitate balanced nutrient management for optimal growth and yield. This research aimed to assess how varying applications of NPK 20-20-10 fertilizer influenced potato growth, yield, tuber quality, agronomic efficiency, and economic viability within tropical climates. The experimental setup involved a randomized complete block design, incorporating four replications across seven distinct treatments: a control, a standard inorganic fertilization regimen, and NPK 20-20-10 applied at 0.50, 0.75, 1.00, 1.25, and 1.50 times the suggested dosage. The findings indicated that applying NPK 20-20-10 significantly enhanced several parameters, including plant height, branch count, tuber count, tuber weight, and overall yield components, when contrasted with the control group. Notably, the 1.25 times recommended dose demonstrated superior performance, leading to a 34.9% increase in tuber number and a 68.6% rise in tuber weight compared to the control. Agronomic effectiveness scores surpassed 100 for dosages ranging from 0.75 to 1.50, with the 1.25 dose registering the peak value. Economic evaluations confirmed the profitability of all NPK treatments, and the 1.25 dose yielded the most favorable R/C ratio and a net profit of IDR 29,053,400. Consequently, the recommended application for potato cultivation is 675 kg/ha of NPK 20-20-10, distributed in three equal parts at planting, four weeks post-planting, and six weeks post-planting. Thus, these results underscore that NPK 20-20-10, when applied at 1.25 times the recommended rate, presents an agronomically effective and economically sound strategy for sustainable potato farming in tropical settings.

Background: Oral health is an important indicator of overall health, well-being, and quality of life. According to the WHO, oral health is a state of freedom from various diseases and conditions, including dental and oral diseases that limit an individual's ability to bite, chew, smile, speak, and psychosocial well-being. Therefore, it is necessary to maintain oral hygiene as an effort to improve oral health. Case report: A 45-year-old man came to Soelastri General Hospital complaining of a large cavity in his upper left tooth. The tooth had been painful for about a year and had not undergone any treatment.Extraoral examination revealed a symmetrical face. Clinical examination of the maxillary left first premolar revealed a large cavity on the distoocclusal surface with pulpal depth.  Discussion: Perforations can be treated through cavity access; the prognosis depends on the elimination and prevention of infection in the perforation area and the choice of material. The success of perforation closure management is influenced by several factors, including the timing of perforation closure, the choice of material used, the location of the perforation, and adequate perforation closure. Conclusion: Case of maxillary left premolar with diagnosis of pulp necrosis which experienced lateral perforation and the area was closed using MTA, then root canal treatment.  

The rapid advancement of digital technology has fundamentally transformed civil legal interactions, making electronic documents such as instant messages, online transactions, and digital contracts primary forms of evidence in many civil disputes. However, their admissibility in judicial proceedings remains fraught with challenges concerning formal and material validity. This study aims to identify juridical and technical obstacles in digital evidence and to formulate an ideal model for civil procedural law that ensures reliable electronic proof. A normative-juridical approach with qualitative analysis was employed, combining doctrinal research through legislative review, jurisprudence, and scholarly literature with case studies of court decisions involving electronic evidence, particularly in divorce disputes. The findings reveal that inconsistent judicial treatment stems from the absence of specific procedural rules in Indonesia’s civil procedure framework still rooted in colonial-era HIR and RBg alongside limited digital infrastructure and low technological literacy among judicial actors. In response, the study proposes an integrated legal construction model featuring explicit provisions in the upcoming Civil Procedure Code, adoption of the functional equivalence principle, institutionalization of digital forensic experts in litigation, and procedural safeguards for vulnerable parties. The research concludes that only through holistic reform of the evidentiary paradigm can Indonesia’s civil justice system guarantee fairness, legal certainty, and relevance in the digital era.

The prevalence of cancer in West Sumatra Province is around 2.4 per 1000 population, higher than the national prevalence of around 1.7 per 1000 population and really requires the development of appropriate prevention and control programs for cancer, especially in West Sumatra. One of the solutions provided by the Cancer Foundation in Padang City to help overcome the pain of children suffering from cancer is the COMPACT (Communication on Palliative Care Treatment) application. This activity is carried out between June and June. September 2024 in around 20 children with cancer. The activity began with creating the COMPACT application, providing socialization on the application regarding self-management of cancer patients in the form of communication in the form of audio-visual hypnocommunication therapy, guided imagery and murrotal Al-Quran to evaluating the self-management of cancer patients. The evaluation results show that there is a decrease in pain intensity before and after being given pain management intervention through the COMPACT application, namely that there is a decrease in the average pain before and after with an average difference of 2.50-2.00 and there is an increase in self-management so it can be concluded that the use of the application COMPACT can be an option for self-management for cancer patients both at home and in hospitalization. It is hoped that this application will be useful for increasing public knowledge in self-management due to cancer at home.
