The agricultural sector plays a strategic role in ensuring national food security, particularly in rural areas where the majority of the population depends on agricultural production. Sememu Village, an agricultural-based community with rice and tobacco as its primary commodities, has faced recurring pest attacks in recent years. Conventional pest control methods in the area have primarily relied on chemical pesticides. However, excessive and prolonged use of these chemicals has resulted in serious problems, including pest resistance, environmental contamination, and potential health risks to farmers and consumers. This study aims to improve farmers’ knowledge and practical skills by introducing an alternative, eco-friendly approach through a training program on the production of botanical pesticides derived from papaya leaves (Carica papaya L.). Papaya leaves are known to contain bioactive compounds such as papain, chymopapain, alkaloids, terpenoids, and flavonoids, which exhibit natural insecticidal properties. The training activities consisted of initial observation, presentation of scientific and practical materials, hands-on practice in the preparation of botanical pesticides, and field testing on rice and tobacco plants. The findings demonstrated that the use of papaya leaf-based pesticides effectively reduced pest feeding activity and increased pest mortality rates, thereby minimizing crop damage. Importantly, this approach did not cause harmful effects on the surrounding ecosystem. The program highlights the potential of botanical pesticides as a sustainable solution for integrated pest management in agricultural villages, contributing both to environmental conservation and farmers’ welfare.

Patients admitted to the Intensive Care Unit (ICU) often experience physiological disturbances caused by both medical conditions and intensive treatment procedures. One of the most common problems encountered is sleep disturbance. Several factors contribute to poor sleep quality in ICU patients, including repeated medical procedures, environmental noise from medical equipment and staff activities, discomfort due to body positioning, frequent interactions with health workers, continuous exposure to lighting, pain, and the underlying disease process. Persistent sleep disturbances can delay the healing process, increase blood pressure, and even elevate the risk of stroke. This study aimed to analyze the relationship between anxiety levels and sleep quality in compos mentis patients in the ICU of Sultan Agung Islamic Hospital Semarang. The research design employed a correlational approach with a cross-sectional method. A total of 30 respondents were selected according to the inclusion criteria. Data were collected using the Pittsburgh Sleep Quality Index (PSQI) to measure sleep quality and the Hamilton Anxiety Rating Scale (HARS) to assess anxiety levels. The Chi-Square test was used for statistical analysis. The results showed an equal distribution of male and female respondents (15 each). Ten respondents had a post-laparotomy medical diagnosis, and the majority belonged to the late elderly age group (10 respondents). Most respondents experienced moderate anxiety (18 respondents), while poor sleep quality was reported by 17 respondents. The Chi-Square test revealed a p-value of 0.001, indicating a significant relationship between anxiety levels and sleep quality. In conclusion, higher anxiety levels were associated with poorer sleep quality among compos mentis patients in the ICU. These findings highlight the importance of nursing interventions that address both the physical and psychological aspects of patients to improve sleep quality and support recovery.

Introduction: The increase in life expectancy among the elderly has directly contributed to the rise in the global elderly population. According to global data, the number of elderly individuals is projected to reach 1.4 billion by 2030. This demographic growth is often accompanied by various health problems associated with aging, such as the decline in vital organ function and the emergence of degenerative diseases. One of the most common degenerative diseases among the elderly is hypertension. Hypertension is widely known as a “silent killer” because it can lead to serious complications, including stroke and heart disease, if not managed properly. A common complaint experienced by individuals with hypertension is headache, particularly in the posterior region, which significantly affects the patient’s quality of life. Management of hypertension can be carried out through pharmacological therapy with antihypertensive drugs as well as non-pharmacological interventions. One of the non-pharmacological approaches increasingly being applied is isometric handgrip exercise, which involves static muscle contractions performed at light to moderate intensity. Method:This study aimed to evaluate the effect of isometric handgrip exercise on pain reduction in patients with hypertension. The research design employed a descriptive case study involving one individual with hypertension who experienced pain complaints. The study was conducted on September 16–18, 2024, at Roujin Home X. The instruments used included observation, interview, and the provision of isometric handgrip exercise therapy. Pain measurement was carried out using a numerical rating scale before and after the intervention. Results:The three-day intervention demonstrated a significant reduction in pain levels. On the first day, the patient reported a pain score of 6, which decreased to 4 on the second day, and further declined to 2 on the third day after the intervention. Conclusion:The findings of this study indicate that isometric handgrip exercise is an effective non-pharmacological method for alleviating acute pain in patients with hypertension. This simple intervention has the potential to be applied as a complementary therapy in elderly care facilities to improve the quality of life of individuals living with hypertension.

Attendance is an essential activity in both educational institutions and companies, serving as an indicator of discipline, presence, and individual responsibility. Conventional attendance systems that still rely on manual journals often face several problems, such as vulnerability to manipulation, data loss, and physical damage. Meanwhile, modern methods such as fingerprint, QR code, RFID, and GPS are not entirely ideal since each has its own limitations in terms of cost, accuracy, user convenience, and potential misuse. For instance, fingerprint systems raise hygiene concerns due to shared use, while QR code and GPS methods are prone to fraud and location spoofing. To address these challenges, this study proposes a face-based attendance simulation system by integrating the YOLOv8 algorithm for face detection and Local Binary Pattern Histogram (LBPH) for face recognition. YOLOv8 was chosen for its ability to detect faces in real time with high speed and accuracy, while LBPH is employed for face recognition due to its robustness in handling variations in facial features and its relatively low computational requirements. This makes the system efficient even when implemented on medium-specification devices. The system was tested on 25 participants with a total of 250 attendance attempts. Based on the confusion matrix analysis, the system achieved outstanding performance with 98.4% accuracy, 98.4% precision, 100% recall, and a 99.2% F1-score. Furthermore, the system automatically recorded attendance dates and times with an average latency of 69.185 ms, proving its capability to operate quickly and reliably in real-world scenarios. Nevertheless, several limitations were observed, such as decreased accuracy when the face moved too quickly during image capture, as well as potential performance degradation under extreme lighting conditions. Despite these challenges, the proposed system demonstrates excellent performance and offers a promising solution for efficient, hygienic, and fraud-resistant attendance management applicable to both educational and professional environments.

Malnutrition is a condition in which the body does not receive enough essential nutrients, such as protein, vitamins, calories, and minerals, which causes various health problems, especially wasting and stunting, making it a serious concern in children. According to the Basic Health Research, the prevalence of malnourished children in Indonesia remained stable at 17.8% between 2016 and 2017 but decreased to 13.8% in 2018. This case study focuses on a 23-month-old girl from Kuala Keureuto Village, who was observed for three weeks through home visits in 2025. The diagnosis of malnutrition was made in accordance with national guidelines outlined in the Indonesian Minister of Health Regulation No. 2 of 2020, regarding child anthropometric standards. Anthropometric measurements showed that the child's height was 78.3 cm and her weight was 8.8 kg. Based on these measurements, her nutritional status was assessed as follows: A height/age Z-score between -2 and -3 SD indicates stunting, a weight/age Z-score between -2 and -3 SD indicates underweight, while a weight/age Z-score below -2 SD and a BMI/age Z-score below -2 SD are considered well-nourished. After confirming the diagnosis, the patient received nutrition education, supplemental feeding, appetite-stimulating supplements, and growth monitoring. In addition, analyses were conducted to identify factors influencing her condition, concluding that the malnutrition observed in this 23-month-old patient was influenced by parenting behavior, parental knowledge, medical history, incomplete immunizations, and environmental factors.

Anomalous positioning is an abnormal position of the fetal vertex (with the small fontanelle as a marker) relative to the maternal pelvis. Oblique malposition is a cause of maternal mortality rate (MMR) of 3-10%. Obesity in pregnancy is a condition characterized by an imbalance between body weight and height. According to WHO data, the prevalence of obesity in 2021 was 340 million, with data in Central Java province reaching 6.62%. In Brebes Regency, the figure was 20.51% (2019). In the Bumiayu Community Health Center, data on obesity in pregnant women reached 63 in 2022. This study aims to provide comprehensive midwifery care for pregnant women, childbirth, postpartum, newborns, and family planning for Mrs. N, 23, with malposition and obesity. This study used a qualitative descriptive method with a comprehensive case study approach. Based on the comprehensive midwifery care provided to Mrs. N, 23, with malposition and obesity, the pregnancy outcome was found to be grade I. Her gestational age was not commensurate with her gestational age. Delivery was performed by vaginal delivery. No problems were found during newborn care up to 28 days. No problems were found during the postpartum period. Mrs. N chose intrauterine contraception (IUD) during pregnancy, but her husband did not allow it due to religious reasons. Appropriate midwifery care during pregnancy, childbirth, newborn care, postpartum care, and family planning is crucial for the health of both mother and baby. This allows early detection of risk factors, preventing potential complications, and reducing maternal and infant mortality.

This research is a library study aimed at analyzing the various reasons for curriculum changes in Indonesia. Curriculum evaluation plays a crucial role in ensuring the quality and relevance of education by adapting to the dynamic changes in society. It helps identify the strengths and weaknesses of the curriculum and provides recommendations for improvement. However, several problems arise during implementation, particularly when teachers feel the time allocated to adapt to the new curriculum is insufficient, coupled with gaps in school facilities that make the implementation appear forced. The evaluation focuses on several key aspects: content, learning strategies, media, student learning outcomes, and teacher readiness, as teachers are the main drivers of knowledge transfer in the classroom. The qualitative descriptive approach, in the form of library research, collects data through systematic reviews, analysis stages, and information extraction from various sources. Over the course of the education system in Indonesia, from 1947 to 2024, the curriculum has undergone numerous changes. While these changes aim to improve the learning process and achieve optimal educational quality, they have had both positive and negative impacts. The influence of political agendas and the priorities of the ruling government have significantly shaped these curriculum changes. Despite these challenges, the rationale behind the changes lies in the effort to improve the learning experience and keep educational content up to date, reflecting the needs of the times. In conclusion, curriculum changes are essential to maintaining educational relevance, but proper preparation, sufficient time for adaptation, and adequate facilities are critical to the successful implementation of these changes. The research highlights the ongoing struggle to balance educational reforms with practical considerations for educators and students alike.

This study aims to analyze the responsibilities of the Witness and Victim Protection Agency (LPSK) and the state in implementing restitution for victims of sexual violence, particularly when the perpetrators are unable to pay or are sentenced to death. The background of this research lies in the weak implementation of restitution, which should be a fundamental right of victims, as illustrated by the case of Herry Wirawan based on the Bandung High Court Decision Number 86/Pid.Sus/2022/PT Bdg. The research addresses two main problems: (1) how the state and LPSK ensure the victims’ rights to restitution under such circumstances, and (2) what obstacles hinder the implementation of restitution based on the decision. The study employs a normative juridical method with a statutory and case study approach. The findings show that the implementation of restitution still faces serious obstacles, such as the absence of technical mechanisms, the lack of designated executing institutions, and the lack of coordination among law enforcement agencies. LPSK plays a role in proposing and calculating restitution amounts but lacks execution authority. Moreover, the state has not yet fulfilled its role as the ultimate guarantor for victims when the perpetrator is unable to comply. In conclusion, Indonesia’s legal system needs to strengthen technical regulations, ensure inter-agency coordination, and affirm the state's role as a guarantor of restitution to achieve meaningful restorative justice for victims of sexual violence

The increase in traffic volume in urban areas often triggers various problems, especially at Road intersection points that have a high level of interaction between vehicles. One of the locations that experience these problems is the intersection with the island of traffic without signal on Jl. Tebu-Jl. Tabrani Ahmad, City Of Pontianak. This study aims to analyze the performance of the intersection in the existing condition and project its performance in the next five years (2030), as well as formulate alternative treatment that can improve the smoothness of traffic. The analysis method refers to Indonesian road capacity guidelines (PKJI) 2023 and modeling using software PTV VISSIM. The data collected include intersection geometry, traffic volume, and vehicle speed. Traffic volumes were obtained through CCTV recordings for three consecutive days, then processed and presented in the form of tables and graphs for easy interpretation. The results of the existing condition analysis showed that the degree of saturation (DS) reached 0.407 with an average delay of 9.539 seconds (Level of Service/LOS B) based on PKJI, while VISSIM simulation resulted in a delay of 12.54 seconds (LOS B). The five-year projection (2030) shows an increase in DS to 0.878 with a delay of 15.177 seconds (LOS C) from PKJI, and 23.35 seconds (LOS C) from VISSIM, which indicates a decrease in Junction performance as traffic grows. Two handling alternatives were analyzed, namely the construction of roundabouts and the implementation of traffic flow management. VISSIM simulation shows that the roundabout can reduce the delay to 14.31 seconds with a queue length of 20.34 m (LOS B), while the flow management produces a delay of 11.81 seconds with a queue of 13.14 m (LOS B). This result confirms that both alternatives are able to improve the performance of the intersection compared to the projected condition without handling, so that it can be a technical recommendation for urban traffic planning in Pontianak.

Distribution is an important aspect that affects the operational efficiency of a company, especially in terms of goods delivery. This study aims to develop an optimization model for LPG gas distribution routes using Excel Solver based on geographic coordinate conversion. In this study, the method used includes converting geographic coordinates from decimal to Degree-Minute-Second (DMS) format, followed by conversion to kilometers to form a more accurate distance matrix. The optimization model was built using the Capacitated Vehicle Routing Problem (CVRP) approach, which takes into account vehicle capacity constraints (a maximum of 560 cylinders per truck) and the limited number of available fleets, which is only one truck. The results show that coordinate conversion produces high accuracy in calculating distances between distribution locations. By using Excel Solver, the optimization solution successfully minimizes the total distance traveled compared to the conventional route, where distribution is carried out more evenly to 57 scattered LPG base locations. The addition of Solver Parameters Evolutionary and All Different constraints proved effective in avoiding duplication of visits and producing optimal distribution routes. This solution not only improves distribution time and cost efficiency, but also improves service to customers by reducing delivery delays. The success of this optimization model is expected to be implemented by other distribution companies to improve their operational performance. This study also highlights the importance of selecting the right software to aid the distribution optimization process. Excel Solver, despite its simplicity, proved highly effective in solving complex distribution routing problems, especially when combined with coordinate conversion techniques that yield more accurate distances. Furthermore, the application of the CVRP method enabled more efficient decision-making in determining distribution routes, taking into account vehicle capacity and fleet limitations.

UMKM Tahu XYZ, a small-scale tofu producer, is currently facing significant challenges in maintaining consistent product quality, primarily due to a high defect rate. Common issues identified include crumbled tofu shapes, overly soft textures, and inconsistent taste, which negatively impact customer satisfaction and business sustainability. This study aims to investigate the root causes of these quality issues and propose practical solutions using the Lean Six Sigma methodology. The research employs a descriptive quantitative approach through the DMAIC framework—Define, Measure, Analyze, Improve, and Control—to ensure systematic problem-solving. Data were collected over a six-month period through direct observation, structured interviews, and review of production records. The analysis identified four dominant types of waste within the production process: unnecessary transportation, product defects, excessive movement, and over-processing. The root causes of these inefficiencies are linked to poor handling of raw materials, variability in soybean quality, and an ineffective production layout that hampers workflow and consistency. To address these problems, the study proposes several targeted interventions, including the redesign of the production layout to optimize flow, the implementation of the 5S (Sort, Set in order, Shine, Standardize, Sustain) workplace organization method, the development of standardized operating procedures (SOPs), and the adoption of improved soybean boiling technology. The implementation of these improvements is projected to significantly reduce product defects, enhance process efficiency, and ultimately increase customer satisfaction. Furthermore, these actions are expected to improve the overall competitiveness of UMKM Tahu XYZ within the highly demanding food industry sector. This research provides actionable insights for other micro, small, and medium enterprises (MSMEs) seeking to apply structured quality control methods to strengthen operational performance and long-term business resilience.

Hypertension is a non-communicable disease (NCD) with a high prevalence in Indonesia and is a major cause of serious complications, such as stroke, kidney failure, and heart disease. The high incidence of hypertension makes this disease a primary focus of NCD control efforts at the primary healthcare level. The Ulee Kareng Community Health Center has implemented a sustainable hypertension control program for the past three years with the aim of reducing the incidence of complications and improving patients' quality of life. This study aims to evaluate the implementation of the hypertension control program using a logic model framework that encompasses five aspects: input, process, output, outcome, and impact. The research method used is descriptive analytic with a mixed methods approach, combining quantitative and qualitative data to obtain a comprehensive overview of program implementation. The results indicate that the hypertension control program at the Ulee Kareng Community Health Center has had a positive impact. In terms of output and outcome, there has been an increase in patient compliance with therapy prescribed by healthcare professionals, a decrease in blood pressure in the majority of patients, and a decrease in the number of hypertension-related complications. This indicates that the program is quite effective in achieving its intended goals. However, several challenges remain. The main problems lie in the suboptimal data recording system and the suboptimal delivery of health education. To improve the program's effectiveness in the future, recommendations include strengthening the monitoring and evaluation system, increasing the capacity of health workers and cadres through training, and developing innovative media and educational strategies to make information more easily understood and applied by the public.
