This study examines the emergence of localized English expressions in Indonesian social media discourse, highlighting how English is adapted and reinterpreted in multilingual digital contexts. While previous studies on English in Indonesia have primarily focused on formal domains such as education and language policy, limited attention has been given to informal online communication where linguistic innovation is highly visible. This study aims to analyze how English lexical items are re-semanticized and creatively transformed by Indonesian users on social media platforms. The study employed a qualitative approach using data collected from Instagram posts and comments, focusing on selected examples of English-derived expressions such as boba, gas, voucher, server, and suamiable. The analysis compares the conventional meanings of these terms in Inner Circle English with their localized meanings in Indonesian usage. The findings reveal that English functions as a flexible linguistic resource, undergoing processes of semantic shift, metaphorical extension, and lexical blending. These localized forms reflect users’ creativity as well as their ability to adapt global linguistic resources to local cultural contexts. The study concludes that English in Indonesian social media is not merely borrowed but actively reconstructed, contributing to the dynamic development of English in the Expanding Circle.

Limited land availability is a major constraint in developing school infrastructure in active urban educational facilities. This study evaluates the classroom development plan at SDN 39 Lubuklinggau from the perspective of a planner, focusing on land limitation, functional needs, safety, constructability, and long-term building performance. A descriptive-evaluative approach was applied through technical observation, document review, alternative assessment, weighted scoring, and risk analysis. The results indicate that horizontal expansion is constrained by limited open space and may reduce internal circulation, student activity areas, and emergency space. Three alternatives were compared: horizontal expansion, building rearrangement, and a two-storey classroom scheme. The two-storey alternative obtained the highest score of 84, compared with 61 for rearrangement and 56 for horizontal expansion. However, its feasibility depends on further soil investigation, structural design, staircase and evacuation safety, utility coordination, construction phasing, and strict site safety control. The study recommends that the planner prioritize detailed site measurement, geotechnical investigation, detailed engineering design, construction safety planning, and post-construction functional evaluation. A vertical classroom strategy can be considered a rational solution for land-constrained schools when supported by accountable technical planning and integrated project control.

This study discusses the concept of polygamy from the perspectives of Islamic law and positive law in Indonesia, focusing on the principles of justice and its impact on women and families. Polygamy is one of the issues in fiqh munakahat that continues to generate debate because it is considered closely related to patriarchal culture, gender inequality, and violence against women. This study aims to analyze the legal basis of polygamy in the Qur’an, the views of scholars of tafsir and fiqh regarding polygamy, as well as the regulation of polygamy in Indonesian legislation. This study employs a library research method with a normative-sociological approach. Data sources were obtained from books of tafsir, fiqh, hadith, Islamic legal literature, and laws and regulations related to marriage in Indonesia. The findings indicate that Islam permits polygamy under very strict conditions, particularly regarding the husband’s ability to act justly both materially and emotionally. However, justice in emotional aspects and affection is considered very difficult for ordinary people to achieve, as emphasized in Qur'an Surah An-Nisa verse 129. In Indonesian positive law, the primary principle of marriage is monogamy, while polygamy is only permitted under certain circumstances with administrative requirements and court approval. This study concludes that the practice of polygamy in the modern era should be understood contextually by considering aspects of public welfare (maslahah), the protection of women’s rights, family justice, and the primary objectives of Islamic law in establishing a harmonious family characterized by sakinah, mawaddah, and rahmah.

This study analyzes the minimum age of marriage in Islamic jurisprudence and compares it with the positive law regulations in Indonesia and Malaysia. Using a normative legal method with comparative and conceptual approaches, the study draws on primary sources, including the Qur'an, hadith, Law Number 16 of 2019 on Marriage in Indonesia, and the Islamic Family Law (Federal Territories) Act 1984 in Malaysia. The analysis focuses on how Islamic legal principles concerning marriage eligibility are interpreted and incorporated into contemporary legal frameworks in both countries. The findings reveal that Islamic jurisprudence (fiqh) associates marital readiness with the concept of baligh (puberty) without prescribing a specific numerical age, whereas state law establishes fixed minimum age requirements to safeguard the rights and welfare of women and children. Indonesia sets the minimum marriage age at 19 years for both males and females, while Malaysia prescribes 18 years for males and 16 years for females, with judicial dispensation available in both jurisdictions under certain circumstances. These legal arrangements demonstrate each country's effort to harmonize classical Islamic jurisprudence with contemporary social protection objectives through institutional ijtihad, reflecting a balance between religious principles, legal certainty, and public welfare in regulating marriage.

Stunting is a multifactorial public health problem influenced by various risk factors that may emerge during the prenatal period. Early identification of stunting risk during pregnancy is important to support preventive interventions. This study aimed to develop a stunting risk prediction model based on maternal prenatal factors using the Random Forest algorithm. Secondary data from 172 pregnant women, consisting of 83 stunting cases and 89 non-stunting cases, were analyzed. The predictor variables included maternal age during pregnancy, height, hemoglobin level, mid-upper arm circumference (MUAC), smoking history, hypertension, asthma, and diabetes mellitus. The research stages consisted of data preprocessing, model training using Stratified 5-Fold Cross Validation, performance evaluation, external testing, and feature importance analysis. Internal evaluation results showed an accuracy of 60%, precision of 60.6%, recall of 57.3%, F1-score of 58.9%, and AUC of 0.6688. External testing yielded an accuracy of 70% and an AUC of 0.6167. Feature importance analysis identified maternal age during pregnancy as the most influential variable in the prediction process. The findings indicate that maternal prenatal factors have potential for early stunting risk identification, although the predictive performance remains moderate. This approach may serve as a foundation for developing early screening tools to support targeted interventions among high-risk pregnancies.

Background: Stroke is a neurological dysfunction caused by impaired blood circulation to the brain. Stroke can cause disability for survivors, one of which is impaired physical mobility due to weakness in the extremities and decreased muscle strength that can hinder the fulfillment of daily life activities. Range of Motion (ROM) and rubber ball grasping are one of the non-pharmacological ways in providing nursing care to ischemic stroke patients according to evidence-based practice (EBP). Purpose: This study aims to explain the process of providing nursing care with Range of Motion (ROM) interventions and rubber ball grasping for the problem of impaired physical mobility in stroke patients in Mina 1 room of RSUDZA. Method: case study with one patient as the subject with impaired physical mobility. Results: what was obtained during 6 days of intervention was an increase in the patient's muscle strength before and after the intervention, which was initially 1, increased to 4. Conclusion: Physical mobility impairment was resolved because the patient's muscle strength increased much better. Suggestion: It is hoped that Dr. Zainoel Abidin Banda Aceh can continue to improve nursing care for stroke patients so that the care provided is more effective and can apply Range of Motion (ROM) and rubber ball grasping as non-pharmacological methods.

This study aims to identify the management system for Taman Imbi by the Department of Public Works and Public Housing (Dinas PUPR) and to analyze its comfort level based on the perceptions of park visitors and street vendors (PKL). Taman Imbi, managed by the PUPR Service (Section for Environmental Management and Parks), is one of the main urban parks in the city center of North Jayapura District. The research uses a descriptive, qualitative approach combined with Likert-scale analysis. Primary data were obtained from questionnaires distributed to 100 park visitors and 10 business actors (PKL) operating around the park. Eight comfort indicators were assessed, based on Hakim (2003): aesthetics, cleanliness, safety, noise, circulation, aroma, physical form, and climate/natural forces. Results indicate that, based on visitor perceptions, the overall comfort level was 56.0% (fairly good), while PKL perceptions were 64.4% (good). Among all indicators, circulation scored the lowest for visitors (46.2%), particularly ease of access. Aroma/odor scored the highest for PKL (80.0%). The study recommends rehabilitating park facilities, reactivating security posts, improving pedestrian and parking access, and clarifying spatial zoning for economic and community activities in the park.

Circulating tumor DNA (ctDNA) has emerged as a promising liquid biopsy biomarker for real-time monitoring of tumor dynamics. In urothelial carcinoma (UC), effective monitoring of treatment response remains a clinical challenge due to the limitations of conventional imaging and invasive procedures. This systematic review aims to synthesize the existing evidence on the association between ctDNA dynamics and treatment response monitoring across various stages and therapeutic settings. A comprehensive systematic review was conducted. We included cohort studies, randomized controlled trials, and meta-analyses that evaluated ctDNA in UC patients undergoing treatment. Data were extracted on patient population, methodology, treatment, sampling strategy, clinical outcomes, and statistical associations. The review encompassed 80 studies. Baseline ctDNA positivity was strongly prognostic, associated with a 4- to 6-fold increased risk of recurrence or death (HR 4.23-6.56). Dynamic ctDNA clearances or significants reduction during treatment, were strongly associated with improved outcomes. Showing hazard ratios for adverse events as low as 0.10-0.31. ctDNA demonstrated time advantages of 53-90 days over radiographic detection. ctDNA is a potent tool for monitoring treatment response in urothelial carcinoma. It provides superior prognostic and offers a significant lead time for detecting treatment failure. Future research must focus on standardizing methodologies and validating ctDNA-guided therapeutic.

This study designs and implements an up-down counter system based on an AT89C2051 microcontroller programmed in assembly using the MC-51 application. The system modifies an existing digital clock board by mapping the display selector pins, seven-segment segment pins, pushbuttons, and buzzer to the microcontroller ports. The research method consists of literature review, hardware identification, algorithm design, assembly programming, program downloading, and functional testing using a 5 V DC supply. The implementation uses a four-digit common-cathode seven-segment display and a multiplexing routine to show the counter value in real time. The functional test shows that the system can display the initial value, increase the value through the up button, and decrease the value through the down button. The display is readable during operation, and the program can run on the target circuit after being downloaded to the AT89C2051. This study confirms that assembly programming on MC-51 can be applied to implement a simple counter system on a reused digital clock circuit. The main limitations are the absence of explicit button debouncing, overflow and underflow protection, quantitative response-time measurement, and non-volatile data retention.

Dredger operations in water-based mining areas have a high occupational risk because they involve a combination of wet environments, mechanical equipment, and electrical systems. The presence of electrical panels, power cables, terminal connections, electric motors, inverters/drives, and protection components on the Dredger requires a sound understanding of Occupational Health and Safety, particularly electrical safety. Water splashes, wet walking surfaces, high humidity, and improper procedures during inspection or cleaning may increase the risk of short circuits, protection trips, and electric shock. Therefore, structured basic safety training is required so that operators are able to identify electrical hazards and implement safe working procedures. This activity aimed to improve operators’ understanding of hazardous electrical components, initial safety briefing procedures, measurement practice and safe handling during trips or short-circuit indications, and the correct and safe use of water pumps for unit cleaning. The activity was carried out through field observation, technical briefing, direct demonstration on the electrical panel and work area, simple measurement practice, and safe cleaning practice. The results indicate that field documentation can serve as an effective learning medium to strengthen operators’ understanding of electrical hazard sources on the Dredger, the application of simple lock out-tag out procedures, the control of wet areas, and the limitation of water spray direction during cleaning activities. Overall, the activity shows that improved compliance with safety procedures may reduce the risk of short circuits and electric shock during operation and maintenance.

In Islam, prayer (salat) is a fundamental obligation that must be performed under all circumstances, including during illness. Muslim patients have high spiritual needs, in which religious practices serve as a source of strength in coping with disease. Although Islam provides concessions (rukhsah) in performing prayer for the sick, limitations in patients’ understanding of how to perform prayer according to their health conditions are still found. This lack of knowledge may affect the proper practice of prayer during hospitalization. Therefore, this study aims to identify patient characteristics related to the practice of prayer, to examine the level of knowledge of the five daily prayers in relation to their practice among patients, and to analyze patients’ overall level of knowledge regarding prayer. This study employed a quantitative method with a cross-sectional design. The results show that patient characteristics, particularly productive age and higher educational level, contribute to their ability to perform prayer during hospitalization. A significant relationship was found between the level of knowledge of prayer and its practice, where better understanding was associated with more optimal religious practice. Overall, most patients had a high level of knowledge of prayer, although a small proportion still had low knowledge, indicating the need for spiritual education. It can be concluded that the level of knowledge of prayer is associated with the quality of prayer practice among Muslim patients at RSUD Haji Makassar. Strengthening spiritual education is needed to support the fulfillment of patients’ religious needs during hospitalization.

Hydrocephalus is defined as active distension of the brain’s ventricular system, resulting from inadequate flow of cerebrospinal fluid from its site of production to its site of absorption into the systemic circulation. Hydrocephalus can affect anyone at any age; pediatric hydrocephalus affects 1 in 1,000 live births and is the most common cause of brain surgery in young patients. Hydrocephalus is a pathological condition characterized by abnormal accumulation of cerebrospinal fluid (CSF) due to increased production, impaired flow, or reduced absorption. Ventricular enlargement occurs in response to increased CSF volume and can lead to structural damage to the brain parenchyma. This condition can be congenital or acquired. One key point in prenatal diagnosis is the differentiation between fetal hydrocephalus and non-hypertensive ventriculomegaly. The former qualifies for intrauterine treatment with good outcomes. However, the latter can result in either favorable or catastrophic outcomes due to a damaging etiology, as seen in viral infections such as Zika virus. For an accurate diagnosis, fetal MRI is performed to detect brain anomalies, in addition to fetal ultrasound (to detect common complications), karyotype testing, and TORCH testing (toxoplasma, rubella, cytomegalovirus, herpes simplex). Obstetric management of fetal hydrocephalus depends on the gestational age at diagnosis and the presence of other anomalies. Treatment options include termination of pregnancy before the fetus is viable, placement of a ventriculoamniotic shunt, cephalocentesis before delivery, and/or cesarean section.

The high volume of fishery waste often poses an environmental burden if not managed appropriately. Conversely, the circular economy concept offers sustainable solutions aligned with Maqasid Shariah principles in environmental preservation (Hifz al-Alam). This study aims to educate and implement the processing of fish waste into high-quality animal feed that meets halal standards (halalan thayyiban). This research employs a qualitative approach using the Asset-Based Community Development (ABCD) method. The stages include socializing the concept of Sharia circular economy, technical training on waste processing, and nutritional content testing of the feed. The findings indicate an 80% increase in community understanding regarding the economic value of waste. Technically, the fish waste processing successfully produced an alternative animal feed with high protein content, free from najis (impurity) through a purification process according to Islamic jurisprudence (fiqh). This education proves that the integration of circular economy and Sharia principles not only reduces environmental impact but also creates sustainable economic added value for local communities.

This study aims to analyze public sentiment toward the hashtag #KaburAjaDulu, which has circulated widely on the social media platform X (formerly Twitter). The hashtag reflects the growing anxiety among the public, especially younger generations, regarding socio-political issues in Indonesia. The data were collected using web scraping techniques, focusing on user-generated tweets that contain the hashtag. A comprehensive text preprocessing phase was conducted to clean the raw data by removing irrelevant elements such as URLs, emojis, numbers, and punctuation. The research applies a hybrid classification approach using a combination of Support Vector Machine (SVM) and Random Forest algorithms to categorize sentiment into three classes: positive, negative, and neutral. The performance of the model was evaluated using metrics such as accuracy, precision, recall, and F1-score to determine the effectiveness of the classification. The study aims to demonstrate that combining algorithms can improve classification performance compared to using a single algorithm. This research contributes to the field of sentiment analysis and provides valuable insights for researchers, policymakers, and social observers in understanding public opinion trends in digital media.
