This study aims to examine the mediating role of Organizational Citizenship Behavior (OCB) in the relationship between Perceived Organizational Support (POS), Perceived Organizational Commitment (POC), and employee performance in a state-owned enterprise in Indonesia. In the context of growing public expectations for improved service quality, organizations are challenged to enhance employee performance not only in formal roles but also in discretionary behaviors. Based on Social Exchange Theory (SET), this research proposes that POS and POC can affect performance both directly and indirectly through OCB. Data were collected through a census of 138 permanent employees at PT Jasa Raharja, East Java Branch. The analysis employed Partial Least Squares Structural Equation Modeling (PLS-SEM) to test the hypothesized relationships. The findings show that POS has a significant positive influence on both OCB and employee performance. On the other hand, POC significantly influences OCB but does not have a direct impact on performance. The results also reveal that OCB plays a partial mediating role in the relationship between POS and performance, while it acts as a full mediator in the relationship between POC and performance. These findings emphasize the importance of fostering OCB within the organization to optimize the impact of support and commitment on employee performance. Encouraging voluntary, extra-role behaviors can bridge the gap between how employees perceive organizational treatment and how they perform. The study suggests practical implications for human resource management in public sector institutions. Policies should focus on building a supportive and engaging work climate that enhances affective commitment and acknowledges employee contributions beyond formal duties. Doing so will not only improve individual performance but also contribute to broader organizational effectiveness in a competitive and service-oriented environment.

Completeness, suitability, and accuracy in filling medical record documents are essential for effective management of patient files, as well as for improving the overall quality of healthcare services. Medical records serve as a critical tool for documenting patient histories, treatments, and decisions made during their healthcare journey, thus impacting the quality of care provided. Incomplete or inaccurate documentation can lead to delays in treatment, miscommunication among healthcare providers, and legal issues related to patient care. Studies have shown that comprehensive medical records are linked to improved patient outcomes and enhanced operational efficiency in healthcare settings (Smith et al., 2019; Johnson & Patel, 2021). This study aimed to assess the completeness of patient medical record documents in the Medical Resume and Informed Consent forms for inpatients with surgical cases at Tgk. Chik Ditiro Sigli General Hospital. Using a descriptive quantitative approach, the research analyzed a random sample of 293 medical documents. The findings revealed that the completeness of medical record documentation was 69% for the Medical Resume sheet and 83% for the Informed Consent sheet. The study concluded that certain sections were either incomplete or omitted, primarily due to the assumption that certain fields were not applicable to the particular patient’s case. This highlights the need for further training and awareness for healthcare staff regarding the importance of complete medical documentation. The hospital should implement stricter guidelines for filling out medical records and ensure that healthcare workers fully understand the significance of accurate and complete documentation. Future research could explore strategies for improving the consistency of medical record documentation and evaluate the impact of training programs on filling medical records (Williams et al., 2020).

Adolescent girls commonly experience menstrual disorders, with a 67.2% incidence of dysmenorrhea and 63.1% of premenstrual syndrome (PMS). Menstrual pain, or dysmenorrhea, is one of the most frequent reproductive health issues experienced by women, affecting both adolescents and adults. This condition can significantly hinder daily activities, which calls for appropriate treatment. Dysmenorrhea can be managed through both pharmacological and non-pharmacological methods. While pharmacological treatments offer quick relief, non-pharmacological approaches are considered safer as they do not induce side effects, unlike medications. One effective form of non-pharmacological therapy is acupressure, which has shown promising results in alleviating menstrual pain. According to a study by Latifah and colleagues, acupressure was proven to be effective in reducing menstrual discomfort. In line with this, a community outreach initiative was conducted to educate and train adolescent girls on acupressure techniques as a form of self-care. From May 5 to 9, 2025, acupressure education was provided to 30 female students at a local school. The training focused on teaching students how to apply acupressure to specific pressure points that relieve menstrual pain, without the need for medication or herbal remedies. Pre- and post-training assessments showed a significant increase in students’ knowledge and skills related to the practice of acupressure. The results indicated that students were able to effectively apply acupressure techniques and felt more confident in managing menstrual pain independently. This approach not only offered immediate relief but also empowered the students with a long-term strategy to manage dysmenorrhea in the future. This activity demonstrated positive outcomes, suggesting that acupressure is a valuable, sustainable solution for menstrual pain relief among adolescents.

Therefore, the enhancement of digital monitoring systems and the strengthening of risk awareness across all departments are crucial aspects that need to be addressed moving forward.This research highlights the strategic value of risk management in supporting organizational resilience and financial health, offering practical insights for companies seeking to optimize their risk governance frameworks.

Hypertension, commonly known as high blood pressure, is a condition where blood pressure in the blood vessels consistently exceeds the normal range of 140/90 mmHg. Central Java Province has the highest prevalence of hypertension in Indonesia, at 13.4%. In 2020, Purbalingga Regency reported 268,936 cases of hypertension. According to data from the Bojongsari Health Center, there were 11,596 hypertension patients in 2023. Among the 13 villages in Bojongsari District, there are villages that have experienced an increase in hypertension cases of over 20% annually, one of which is Karangbanjar Village, with 542 cases of hypertension in 2022 and an increase to 858 cases (26%) in 2023. Hypertension treatment can be done through complementary therapy such as progressive muscle relaxation therapy and hydrotherapy. This Community Service Program (PkM) was attended by 20 participants. The results from the pre-test to the post-test showed an increase in the average score, from 59 to 81.5. The evaluation of participants' skills indicated an improvement, with 90% in the “good” category and 10% in the “adequate” category. In addition, there was a significant change in participants' blood pressure after receiving therapy. This activity was carried out using lectures and discussions, with PowerPoint presentations, leaflets, and videos demonstrating how to perform progressive muscle relaxation therapy and hydrotherapy. This educational activity showed an increase in knowledge among the elderly in performing progressive muscle relaxation therapy and hydrotherapy to reduce hypertension.

Hypertension is a condition characterized by elevated blood pressure, where the systolic pressure exceeds 140 mmHg and the diastolic pressure exceeds 90 mmHg. If not properly treated, hypertension can lead to severe complications, increased morbidity, and even mortality. This condition occurs when the heart works harder than usual to pump blood (systolic) and the blood flow returning to the heart (diastolic) also experiences increased pressure. One of the efforts to prevent the progression of hypertension from a primary to a secondary stage is through non-pharmacological treatments. One such treatment includes the use of natural remedies like celery leaves. Celery leaves contain active compounds such as flavonoids and potassium that are believed to help lower blood pressure by relaxing blood vessels and increasing the excretion of sodium through urine.This community service activity was carried out in Purwodadi Village and aimed to increase public awareness, especially among families, regarding hypertension and its non-pharmacological management using natural ingredients that are easy to find and affordable. The method used involved health education through counseling and direct demonstrations of how to prepare and consume celery leaf boiled water. Participants were actively involved in learning how to select, clean, boil, and properly consume the celery leaf water as a herbal drink.The results of the activity showed a significant improvement in community knowledge and understanding related to hypertension and the benefits of using celery leaves as a traditional remedy. It is hoped that after this activity, the local community will be able to independently apply this knowledge and routinely use boiled celery water as a preventive measure to maintain normal blood pressure and reduce the risk of complications. This effort is part of promotive and preventive health services to improve the quality of life and promote a healthy lifestyle at the village level.

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

Football is a sport that requires mastery of basic techniques, one of which is dribbling. Dribbling techniques are very important because they serve to control the ball, pass opponents, and create opportunities in the game. Based on initial observations at SSB Selection FC Pabuaran, Cirebon Regency, it is known that the mastery of dribbling techniques in U-14 athletes is still relatively low. This is shown through unfocused gaze when dribbling, improper touching, and lack of balance when dribble, which has an impact on the effectiveness of the game and the team's overall performance. One of the factors that causes the weakness of dribbling ability is the lack of variety of exercises, especially those that emphasize the aspects of speed and agility. Exercises with the zig-zag trajectory method are an effective form of exercise to improve speed, agility, and ball control. This method helps hone motor response, maneuver accuracy, and dribbling skills in dynamic game conditions. This study aims to find out the extent of the influence of dribbling practice using the zig-zag trajectory method on increasing dribbling speed in U-14 football athletes at SSB Selection FC Pabuaran. The research uses a quantitative approach with experimental methods. Data collection techniques were carried out through observation and dribbling tests before and after treatment. The results of this study are expected to provide an empirical picture of the effectiveness of zig-zag training on the technical aspects of the game of football at an early age. In addition, this research is also expected to be a reference for coaches in designing a more structured training program that is in accordance with the development needs of young athletes. Thus, the development of basic techniques from an early age will be more optimal and contribute to the improvement of national football achievements in the future.

This study aims to improve the learning outcomes of underhand passing skills through the application of play-based methods to fifth and sixth grade students at SDN 1 Bumijawa. This study used a quantitative approach with a One Group Pretest and Posttest experimental design. The sample in this study was 15 students. Data were collected through underhand passing skills tests conducted before and after treatment. The results showed a significant increase in underhand passing skills after students participated in learning using the play-based method. This method has been proven to be able to increase students' interest, active participation, and understanding of basic volleyball techniques. In addition, the application of the play-based method also creates a more enjoyable learning atmosphere and reduces student boredom. This method directly involves students in practical activities, so that students not only understand the theory but also can apply it in real games. Play activities carried out in small groups allow students to learn from each other and increase self-confidence. Improvement in underhand passing skills also shows that the play-based method is effective in developing fine motor skills needed in volleyball. Therefore, the play-based method can be used as an alternative strategy in learning Physical Education, especially volleyball material in elementary schools. This study suggests that Physical Education teachers implement play-based methods more widely to maximize student learning and learning outcomes, as well as increase their motivation and enthusiasm for sports. Furthermore, implementing play-based methods can also improve teamwork among students, a crucial aspect of volleyball. With a more fun and interactive approach, students are more motivated to practice and master the skills taught.

Chronic Energy Deficiency (CED) in pregnant women remains a major nutritional problem in Indonesia and contributes to various maternal and neonatal complications. CED reflects a long-term energy and macronutrient deficit, often influenced by inadequate nutritional intake and socioeconomic limitations. This study aims to analyze nutritional intake and economic status as risk factors for Chronic Energy Deficiency (CED) in pregnant women in the Patilanggio Community Health Center (Puskesmas) working area. This study used a quantitative observational design with a cross-sectional approach. The study sample consisted of 30 pregnant women selected using a total sampling technique. Data were collected through interviews using a respondent characteristics questionnaire and food recall to assess energy and protein intake, as well as Mid-Upper Arm Circumference (MUAC) measurements to determine CED status. Data analysis was conducted descriptively and cross-descriptively. The results showed that all respondents had energy and protein intakes below 90% of the Recommended Dietary Allowance (RDA) and all were categorized as CED based on the MUAC measurement. All respondents were also categorized as low economic status, reflecting a homogeneous socioeconomic condition. These findings indicate that CED in pregnant women at the study site is associated with inadequate nutritional intake and limited economic status. In conclusion, CED in pregnant women is a chronic nutritional problem influenced by nutritional and socioeconomic factors, necessitating comprehensive prevention and treatment efforts based on primary health care services.

In perceiving the quality of service, satisfaction, or image, a person would base the perception on the values felt by the patients. The research aimed at analyzing the influence of service quality on the reuse of inpatient services at Hospital X. This was an analitic survey research with the cross sectional study design. Responden taken as samples were as many as 120 people. Data collected through an interview, questionnaire, and documentation. Data were analyzed using the descriptive statistics analysis namely calculating the average, percentage, frequency tables and inferential statistics through the Chi-square test, multivariate analysis through the multiple logistic regression analysis. The research result indicates that the influence of service quality with the inpatient reutilization in general hospital X was significant, that is service quality of administration (p = 0,032), service quality of doctors (p = 0,001), service quality of nurses (p = 0,000), service quality of pharmacist (p = 0,000), service quality of instruments (p = 0,020), and quality service of treatment rooms (p = 0,009). The variable of the nurses service quality and pharmacist’s quality are the most influential variables on quality service with the inpatient reutilization.

This study was conducted with the aim of determining the extent to which leg power training through the box jump method influences the increase in volleyball smash jump height in extracurricular participants at SMK Negeri 1 Kuningan. Volleyball requires good physical abilities, especially explosive leg muscle power, because this skill plays a very important role in performing the smash movement as the main form of attack. One form of training that is believed to be able to increase explosive power is box jump training, which is a type of plyometric training that emphasizes repeated jumping movements with high intensity. The research method used was an experiment with a one group pretest-posttest design. The study involved a sample group consisting of 15 students, taken using a total sampling technique from all volleyball extracurricular members. The data collection instrument used the vertical jump smash test according to Ali Maksum. The test was conducted in two stages, namely before treatment (pretest) and after treatment (posttest). The results of data analysis showed a significant increase after being given treatment in the form of box jump training. This is evidenced by a significance value (p) of 0.000 which is smaller than 0.05, so it can be concluded that there is a real difference between the pretest and posttest results. In other words, box jump training has been shown to be effective in increasing smash height. These findings indicate that training programs designed to incorporate plyometric elements, particularly box jumps, can optimally develop leg muscle explosive power. Therefore, this study recommends that coaches and sports teachers incorporate box jumps as a primary training component in volleyball skills development programs, significantly improving players' offensive performance.

Osteoporosis is a metabolic bone disorder characterized by decreased bone density, resulting in brittle, porous, and easily broken bones. This condition is more common in the elderly, especially women over 60 years of age, due to hormonal changes, the aging process, and lifestyle factors. Common clinical manifestations experienced by sufferers include back pain that can interfere with daily activities and reduce quality of life. Osteoporosis treatment does not only rely on pharmacological therapy, but can also be done through non-pharmacological therapies such as progressive muscle relaxation techniques that aim to reduce muscle tension and pain perception. This study aims to determine the effect of progressive muscle relaxation techniques on pain reduction in elderly osteoporosis sufferers in Bangun Rejo Village, Tanjung Morawa District, North Sumatra Province. The research method used a quasi-experimental design with a pre-test post-test control group design. The study involved 28 elderly respondents who met the inclusion criteria, divided into two groups: an experimental group that received progressive muscle relaxation intervention and a control group that did not receive intervention. The intervention was carried out in a structured manner according to standard procedures throughout the study period. Pain levels were measured using a numeric pain scale before and after treatment. Data analysis showed a significant reduction in pain levels in the experimental group compared to the control group, with a p-value of 0.040. These results indicate that progressive muscle relaxation techniques are effective as a non-pharmacological method for reducing pain in elderly people with osteoporosis. The findings of this study are expected to provide input for healthcare professionals, particularly nurses, in developing simple, safe, and affordable interventions to improve the quality of life of elderly people with osteoporosis, as well as encourage the routine implementation of this therapy in primary and community healthcare settings.

The purpose of this study was to understand the effect of using Canva-based learning media on the creativity of eleventh-grade students in economics. The background of this study stems from the low level of student learning creativity caused by the minimal use of innovative and engaging media in the learning process. Creativity is an important aspect in economics learning because it encourages students to think critically, create solutions, and understand abstract concepts more contextually. Static and monotonous learning media such as blackboards and textbooks often do not sufficiently stimulate student interest and participation. Therefore, a more interactive and visual approach is needed, one of which is using Canva. Canva is an online graphic design platform that allows teachers and students to easily create presentations, infographics, and other visual materials. Using Canva in learning can provide a more enjoyable learning experience and motivate students to be actively involved. This study used a quantitative method with a one-group pretest-posttest pre-experimental design. Data analysis was carried out by comparing creativity scores before and after treatment. Student creativity was measured using a test instrument that included aspects of fluency, flexibility, originality, and elaboration. The study subjects were 34 11th-grade students at SMAN 1 Tulungagung. The results showed a significant difference in scores between the pretest and posttest results, indicating that the use of Canva-based learning media had a positive impact on increasing student creativity. Students became more active in expressing ideas, more daring to experiment with concepts, and better able to present learning outcomes visually and attractively. These findings support constructivism theory, which states that effective learning occurs when students actively construct knowledge through meaningful experiences.

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

Diarrhea remains a major health problem, contributing significantly to morbidity and mortality rates in children, especially in developing countries like Indonesia. This disease is often linked to poor sanitation, lack of access to clean water, and a lack of public understanding of proper hygiene practices. Toddlers are the most vulnerable group to diarrhea because their immune systems are not yet fully developed. Current diarrhea management efforts rely heavily on providing oral rehydration salts (ORS) and, in some cases, the use of antibiotics. However, pharmacological approaches are not always available or appropriate in all situations. Therefore, alternative treatments are needed that are safe, readily available, and scientifically proven to be effective. One natural ingredient with significant potential for treating diarrhea is honey. Honey is known to contain various active substances such as enzymes, antioxidants, and antimicrobial compounds that can fight various pathogens that cause diarrhea. Furthermore, honey is also known to help repair the integrity of the intestinal mucosa, stimulate the growth of beneficial bacteria in the digestive tract, and accelerate the healing process. Although the health benefits of honey are well-known, public knowledge—especially among mothers—about its use as an adjunct therapy for diarrhea remains limited. Recognizing the importance of mothers' role in caring for sick children, especially during diarrhea, educational interventions are needed to improve their understanding. This educational activity aims to equip mothers with accurate, easy-to-understand information that can be applied in their daily lives. In this case, the counseling was conducted at PMB Andina Palembang using communicative media such as leaflets and accompanied by live demonstrations to increase information absorption. To measure the effectiveness of this activity, evaluations were conducted through pretests and posttests using structured questionnaires. The results obtained showed a significant increase in mothers' knowledge scores after participating in the counseling.

Diarrhea remains the leading cause of morbidity and mortality among infants in Indonesia, especially in areas with limited access to clean water and sanitation. This community service activity aims to improve mothers' understanding of the signs and symptoms of diarrhea in children, raise mothers' awareness of maintaining their children's hygiene and health to prevent diarrhea, and provide practical training on the initial treatment of diarrhea. The methods used include interactive lectures, group discussions, demonstrations on making oral rehydration solution (ORS), handwashing practice, and distribution of leaflets. The participants consisted of 30 mothers of young children in Bangun Rejo Village, Tanjung Morawa Subdistrict. Evaluation was conducted using pre-test and post-test knowledge assessments. The results of the activity showed a significant increase in mothers' knowledge regarding the prevention and management of diarrhea. Participants were able to identify diarrhea symptoms, practice making ORS, and were more prepared to take their children to healthcare facilities if dehydration signs were present. This activity demonstrated that community-based health education is effective in enhancing mothers' knowledge and preparedness in preventing diarrhea.

The experimental class was given the treatment of the application of the SSCS learning model, while the control class was given learning without the SSCS model. The results of the data hypothesis test analysis technique used the right-hand t-test. Based on the analysis of research data, it was obtained that the tcount of 2.07 was greater than the ttable of 1.67 (dk = 67, α = 0.05) with the category of increasing students' understanding of concepts of 0.74 in the high category. The results of the study show that the Search, Solve, Create, and Share (SSCS) learning model can improve students' understanding of the concept of buffer solutions in class XI MIPA SMAN 7 Pekanbaru.

Preeclampsia is a severe pregnancy complication characterized by hypertension and signs of organ damage, with a multifactorial etiology involving maternal, genetic, and environmental interactions. This study aims to analyze determinants contributing to the occurrence of preeclampsia through a comprehensive literature review. The research method involved an in-depth analysis of 15 scientific journals, consisting of 8 national publications from Google Scholar and 7 international publications from PubMed, selected based on relevance, credibility, and publication date. Data from these sources were synthesized to identify common risk factors, biological mechanisms, and preventive measures. The findings indicate that the primary risk factors for preeclampsia include a history of chronic hypertension, obesity, gestational diabetes, nulliparity (first pregnancy), and a family history of preeclampsia. Nutritional deficiencies, particularly low calcium and vitamin D intake, are also significantly associated with increased risk. Furthermore, immunological factors such as abnormal maternal immune tolerance, as well as placental dysfunction leading to poor perfusion, play a crucial role in the pathogenesis of preeclampsia. The interplay between these factors suggests that preeclampsia is not caused by a single mechanism, but rather by a complex network of physiological, metabolic, and genetic influences. This complexity underscores the importance of early risk factor identification and intervention strategies during antenatal care. Preventive efforts may include nutritional supplementation, weight management, blood pressure monitoring, and targeted medical interventions for high-risk individuals. In conclusion, preeclampsia remains a significant contributor to maternal and perinatal morbidity and mortality worldwide. Understanding its determinants enables healthcare providers to implement timely preventive measures and reduce its negative impacts on both mother and fetus. Further research is warranted to elucidate the precise mechanisms underlying these determinants, potentially paving the way for more effective prevention and treatment strategies.

Welding is one of the most essential metal joining processes in manufacturing, construction, and industrial applications, where Shielded Metal Arc Welding (SMAW) remains widely used due to its flexibility, cost-effectiveness, and ability to be applied in various welding positions. This study aims to analyze the effect of welding position variations on the mechanical properties of SS400 steel, particularly in terms of tensile strength, bending strength, and microstructural characteristics. The experimental method was conducted using 6 mm thick SS400 steel with E6013 electrodes of 2.6 mm diameter in three welding positions: 1G, 2G, and 3G. The welded specimens were then tested through tensile testing (ASTM E8) and bending testing (ASTM E190-14), followed by microstructural analysis in the weld metal area. The results revealed that welding position significantly affects the mechanical properties of welded joints, where the 3G position produced the highest tensile strength of 188.48 kgf/mm², while the 2G position produced the lowest tensile strength of 113.70 kgf/mm². Conversely, the bending test showed that the 2G position provided the maximum bending strength of 1394 kgf/mm², followed by 3G and 1G positions. Microstructural observations demonstrated variations in the distribution of ferrite, pearlite, martensite, and cementite phases across different welding positions, with the dominance of ferrite and pearlite in the 3G specimen contributing to higher tensile strength, while the dominance of martensite and cementite in the 2G specimen enhanced hardness and bending resistance. Overall, this study confirms that welding position plays a crucial role in determining the quality of SS400 welded joints, and the findings are expected to serve as practical guidance for industry in selecting appropriate welding positions for construction needs, while encouraging further research with additional variables such as electrode type, welding current, and post-weld heat treatment to achieve a more comprehensive understanding.
