This study aims to describe Sundanese language learning discourse in the eleventh grade at SMA Negeri 8 Bandung city based on the components of learning discourse. The study employed a qualitative approach with a descriptive method. Data were collected through observation using the non-participatory observation method (SBLC) and recording techniques. The data consisted of recorded utterances during Sundanese language learning activities, which were then transcribed into written form. Data analysis was conducted using content analysis and hermeneutic techniques. The results showed that the learning process consisted of opening, core, and closing activities using the Cooperative Learning model. The components of learning discourse identified included opening and closing conversations, participant cooperation, speech acts, and the nature of utterance sequences. The interaction demonstrated the use of quantity and quality maxims, locutionary, illocutionary, and perlocutionary speech acts, as well as chained utterance sequences in the form of question-and-answer interactions between teacher and students. The findings also revealed that the learning process tended to be teacher-centered, as the teacher was more dominant in directing classroom interaction, although the communication remained interactive and supported the achievement of learning objectives.

Cognitive development is an important aspect of early childhood growth because it forms the foundation for children’s abilities to think, remember, understand concepts, solve problems, and make decisions. Early childhood is often referred to as the golden age since development occurs very rapidly during this period, requiring appropriate stimulation from the surrounding environment, particularly the family. In this context, parents play a crucial role through the parenting styles they apply in daily life. This study aims to examine the relationship between parenting styles and early childhood cognitive development based on findings from previous research. The method used is a narrative review by analyzing relevant scholarly articles published between 2020 and 2026. Articles that met the inclusion criteria were then analyzed descriptively to identify the relationship between parenting styles and children’s cognitive development. The results of the review of 15 selected articles indicate that there is a significant relationship between parenting styles and early childhood cognitive development. Authoritative parenting emerged as the most consistently positive style, characterized by effective communication, emotional support, balanced supervision, and opportunities for children to develop independent thinking skills. Other factors, such as parents’ educational level, involvement in children’s learning activities, and a supportive learning environment, also contribute to cognitive development. In conclusion, authoritative parenting is considered the most effective approach in supporting optimal cognitive development in early childhood.

Nutritional problems among adolescents are increasingly associated with unhealthy dietary habits and low physical activity, contributing to the rising prevalence of overweight. According to the 2023 Indonesian Health Survey, overweight prevalence among adolescents ranges from 12% to 16.2%. This study aimed to develop Zea Coffee Tab, a functional beverage made from Robusta coffee and corn silk containing bioactive compounds, including caffeine and flavonoids, which may support metabolism and body fat oxidation. An experimental method with a Completely Randomized Design (CRD) was employed. The evaluated parameters included organoleptic tests (hedonic and hedonic quality) involving 30 semi-trained panelists, proximate analysis, and identification of bioactive compounds. Data were analyzed using the Kruskal–Wallis, Mann–Whitney, One-Way ANOVA, and Duncan’s multiple range tests. Three formulations were tested: F1 (30% Robusta coffee:70% corn silk), F2 (50%:50%), and F3 (70%:30%). The findings showed that F3 was the most preferred formulation, with an acceptance score categorized as “very much liked.” The product contained energy ranging from 319.20–324.26 kcal/100 g, protein 5.12–5.34%, fat 0.48–0.58%, carbohydrates 73.85–74.51%, moisture 9.12–9.66%, ash 2.10–2.32%, caffeine 182.45–205.86 mg/100 g, and flavonoids 4.28–6.03 mg/100 g. Zea Coffee Tab has the potential to serve as a healthy functional beverage for overweight adolescents.

This study aims to identify the pragmatic failures of Large Language Models (LLMs) and the biases of Anglophone-based AI moderation algorithms in detecting Indonesian hate speech expressed through sarcasm, satire, euphemism, and local cultural metaphors. It also examines the extent to which AI systems understand and interpret the pragmatic meanings within the corpus. This study employs a qualitative descriptive approach with a comparative design. Data were collected through the documentation of hate speech expressions on social media containing elements of local cultural hatred. The data were analyzed using qualitative descriptive methods with pragmatic and thematic approaches. The findings show that all corpus data contain political satire and indirect hate expressed through irony, sarcasm, absurd metaphors, and popular culture wordplay. Testing with Claude AI showed that the system was capable of identifying the data as implicit criticism and recognizing the pragmatic functions of emoticons and contextual meanings in the utterances. However, the analysis also demonstrated limitations in understanding local sociocultural contexts, particularly the metaphors “daun nangka” and “daun sawit,” which were interpreted merely as absurd humor. These findings indicate that AI detection accuracy does not necessarily reflect a deep pragmatic and cultural understanding within the Indonesian context.

This study aims to describe the level of understanding of grade IV students of SD HKBP Perdamean regarding environmental pollution. The research method used is descriptive with a focus on depicting student understanding based on the indicators that have been set. The research data shows that students' understanding is in the category quite well, although it is not even in every indicator. Students better understand aspects of direct action such as keeping the environment clean, planting trees, and saving on the use of plastic. However, understanding of the causes and impacts of environmental pollution, such as littering, river pollution, waste incineration, and air pollution, is still relatively low. In general, the results of the study show that students' understanding is still dominant in simple practical knowledge, so it does not fully cover the concept of environmental pollution and causes. These findings underscore the need for more contextual, student-centered, and hands-on learning that integrates real-world experiences with scientific concepts. Thus, a more interactive and environment-based learning strategy is expected to improve students' overall understanding of environmental pollution and its impact on life.

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.

Project scheduling is a critical aspect of ensuring the successful implementation of construction projects, particularly bridge projects that involve a high degree of complexity. Poor schedule quality may result in project delays, inaccurate critical path identification, and inadequate project control. This study aims to evaluate the schedule quality of a pile slab bridge project using the Defense Contract Management Agency (DCMA) 14-Point Schedule Assessment method, supported by Oracle Primavera P6 software. The study employed a quantitative descriptive method with a case study approach applied to an existing baseline schedule. The assessment results indicate that several parameters have satisfied the DCMA standards, including relationship type, hard constraints, soft constraints, negative float, large duration, and invalid progress. Conversely, several parameters remain non-compliant with the established standards, namely network logic, positive lag, large float, resources/cost, and the Baseline Execution Index (BEI). This study concludes that the project schedule has not fully adhered to the principles of a network-driven schedule and continues to function primarily as an administrative time schedule. The findings of this study offer practical contributions to construction project management by providing recommendations that encompass the refinement of network logic relationships, reduction of excessive lag usage, implementation of resource and cost loading, and progress updates based on the established baseline, thereby enabling the schedule to serve as a more effective, reliable, and integrated project control tool

ASTM A36 steel has relatively low hardness and corrosion resistance, making surface treatment necessary to improve its material properties. This study aims to determine the effect of temperature and holding time variations in the pack carburizing process on the hardness, corrosion rate, and microstructure of ASTM A36 steel. The pack carburizing process was carried out using coconut shell charcoal as the carburizing medium with temperature variations of 850°C, 900°C, and 950°C and holding times of 20, 40, and 60 minutes, followed by quenching in distilled water. Hardness testing was conducted using the Rockwell B scale (HRB) method, corrosion rate testing was performed according to the ASTM G31 method, and microstructural observations were carried out using Scanning Electron Microscopy (SEM). The results showed that increasing the temperature and holding time improved the hardness and corrosion resistance of ASTM A36 steel. The highest hardness value was obtained at a temperature of 950°C with a holding time of 60 minutes, reaching 114.1 HRB. Microstructural analysis revealed the formation of a martensitic phase on the specimen surface after the carburizing process.

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that may persist into adulthood and affect academic, social, and occupational functioning. In adult patients, ADHD is frequently associated with an increased risk of Substance Use Disorder (SUD), raising concerns regarding the potential for misuse and dependence related to stimulant medications used in ADHD therapy. This study aimed to evaluate the effectiveness of pharmacotherapy for adult ADHD and to review the risk of stimulant misuse and dependence based on current scientific evidence. The method employed in this study was a literature review using data obtained from national and international journals indexed in Scopus, PubMed, and Google Scholar published between 2017 and 2026. The findings indicated that stimulant medications, such as methylphenidate and amphetamine, were effective in reducing the core symptoms of ADHD by increasing dopamine and norepinephrine activity in the central nervous system. Most studies reported that the use of stimulant medications at therapeutic doses and under medical supervision was not significantly associated with an increased risk of substance misuse or dependence. The risk of misuse was more commonly observed in cases involving non-medical use and inadequate clinical monitoring. In addition to pharmacological therapy, non-pharmacological approaches such as cognitive behavioral therapy (CBT) also contributed to improving treatment outcomes and patients’ quality of life. Therefore, the use of stimulant medications in adult ADHD patients may be considered relatively safe and effective when administered rationally, individually, and under appropriate medical supervision.

This study aims to overhaul the conventional understanding of tourism through a missiological lens, by positioning social interactions at the Parbubu Tarutung Soda Water Tourism Object as the locus of Missio Dei (God's Mission) manifestation. Amidst the tendency of modern humans to be trapped in egocentrism, alienation, and minimal openness due to secular routines, God is present with a mission to transform human relations. Using a qualitative descriptive-theological method, this study analyzes three axes of social interaction (inter-tourists, tourists-managers, and tourists-local communities). The results of field research indicate that although the pattern of interaction between visitors is still minimalist and egocentric-group due to a purely physical recreation orientation, there is a strong spiritual modality in the service aspect (hospitality) of the managers that reflects the restoration of the image of God (Imago Dei). The absence of social conflict and the presence of sincere hospitality are identified not merely as business strategies, but as real implications of the work of the Holy Spirit who precedes the church (prevenient grace) in destroying human egoism. This study concludes that tourism can be an eschatological means by which social interactions are transformed into encounters that bring about God's Shalom, meaning that tourism can be a way to bring about God's peace through authentic encounters between tourists, rather than simply ordinary tourist transactions. The author recommends the reconstruction of public spaces in this destination as inclusive communal spaces that facilitate reconciliation and social transformation.

Type 2 diabetes mellitus is a chronic metabolic disease characterized by hyperglycemia due to impaired insulin secretion, insulin resistance, or a combination of both. HbA1c levels are used as an indicator of long-term glycemic control in patients with type 2 diabetes mellitus. Insulin therapy is one of the treatment options given to help achieve glycemic control targets. The purpose of this study was to determine the difference in HbA1c levels of type 2 diabetes mellitus patients with insulin and non-insulin therapy at PKU Muhammadiyah Gamping Hospital. This research method used a descriptive study with a cross-sectional approach. The subjects in this study were 80 type 2 diabetes mellitus patients who had used insulin and non-insulin therapy for less than 1 year, using Purposive Sampling techniques and data analysis using SPSS with Chi-Square and Mann-Whitney tests. This study has obtained ethical approval from PKU Muhammadiyah Gamping Hospital. This study shows that the characteristics of gender and age of type 2 DM patients with insulin and non-insulin therapy are dominated by women at 60.0% and 43.3%, while elderly patients at 60.0% and 53.3%. Of the 50 patients using insulin, 45 patients (90.0%) had controlled HbA1c and 5 patients (10.0%) were uncontrolled. Meanwhile, all non-insulin patients, 30 patients (100%), had uncontrolled HbA1c. Based on this study, there is a significant difference in HbA1c levels between type 2 diabetes mellitus patients with insulin and non-insulin therapy with a p-value <0.001. Patients using insulin therapy tend to have better glycemic control than patients not using insulin therapy.

The area and distance between buildings at POLINELA Campus make the presence of adequate connector roads an important necessity to support the mobility of the academic community. This study aims to optimize the scheduling of flexible pavement construction for the POLINELA Connector Road using the Critical Path Method (CPM) based on Microsoft Project 2021. The research method used is descriptive quantitative by processing the Budget Plan (RAB) data into a project schedule consisting of 11 main activities. CPM analysis is used to determine the sequence of work, dependencies between activities, the critical path, and project completion time. The results show that the total project duration is 23 calendar days (May 11–June 6, 2026). CPM analysis identified 10 activities on the critical path with zero float, while embankment work is a non-critical activity with time flexibility. Applying a Start-to-Start (SS) relationship with a 3-day lag between excavation and embankment work allows parallel implementation, reducing the project duration by 4 days (14.8%) compared to the conventional Finish-to-Start (FS) scenario. These results indicate that implementing CPM through Microsoft Project 2021 can increase execution time efficiency, simplify schedule control, and support decision-making in road construction project management.

Diesel engines are widely used in the transportation and industrial sectors due to their high thermal efficiency and good operational durability. However, increased fuel consumption due to inefficiency of the injection system remains a common problem. Injector characteristics, particularly nozzle diameter and injection pressure, are important factors that affect the quality of fuel atomization, air-fuel mixing, and combustion efficiency. An inappropriate combination of parameters can cause suboptimal combustion and increase fuel consumption. This study aims to analyze the effect of variations in nozzle diameter and injection pressure on fuel consumption efficiency in diesel engines. The method used is an experiment with variations in nozzle diameter of 0.150 mm, 0.152 mm, and 0.154 mm and injection pressures of 400 bar, 420 bar, and 440 bar. Tests were conducted at engine speeds of 500 rpm, 1000 rpm, and 1500 rpm with a fuel consumption measurement time of one minute for each parameter combination. Fuel consumption was measured using the volumetric method and analyzed through the fuel volumetric flow rate, fuel mass flow rate, Brake Power (BP), and Brake Specific Fuel Consumption (BSFC). The results showed that the combination of a nozzle diameter of 0.150 mm and an injection pressure of 400 bar produced the lowest BSFC value, thus providing the best fuel consumption efficiency. Meanwhile, the combination of a nozzle diameter of 0.152 mm and an injection pressure of 420 bar showed the closest condition to optimal because it was able to provide a balance between atomization quality and the amount of fuel injected, resulting in efficient and stable combustion. Thus, the efficiency of a diesel engine is influenced by the balance of nozzle size and injection pressure, not solely by the lowest fuel consumption.
