Student dropout in higher education remains a persistent socioeconomic challenge, yet many predictive models reported in the literature are methodologically compromised by randomized cross-validation schemes that introduce temporal data leakage and artificially inflate predictive performance. This study proposes a longitudinal prescriptive learning analytics framework integrating three complementary methodological components: a Leave-One-Cohort-Out (LOCO) temporal validation protocol, a hybrid SMOTE-ENN class balancing strategy, and temporal velocity feature engineering derived from Learning Management System (LMS) behavioral trajectories. The framework was evaluated on a longitudinal dataset comprising 464,739 enrollment records and 77 features. Five predictive algorithms—XGBoost, LightGBM, CatBoost, Random Forest, and Logistic Regression—were comparatively assessed on a strictly isolated blind holdout cohort (2022), with CatBoost emerging as the champion estimator, achieving a PR-AUC of 0.8859, a Macro F1-Score of 0.9143, and the lowest Brier Score (0.0221), thereby demonstrating superior calibration and discriminative capability under severe class imbalance (93:7 ratio). Comprehensive ablation analysis revealed that temporal velocity features function not merely as additive predictors, but as a structural prerequisite enabling Synthetic Minority Oversampling Technique with Edited Nearest Neighbors (SMOTE-ENN) to generate high-quality synthetic boundary instances; removing these features reduced minority-class precision from 0.8302 to 0.6721. To operationalize predictive outputs into actionable intervention pathways, Diverse Counterfactual Explanations (DiCE) were implemented under a three-tier causal constraint architecture on 96 borderline high-risk students, generating 384 feasible intervention scenarios exclusively targeting forward-looking behavioral velocity metrics without constraint violations. Collectively, these findings advance the paradigm of prescriptive learning analytics by providing educational institutions with interpretable risk diagnostics and operationally feasible intervention guidance grounded in empirically validated behavioral and temporal dynamics.

People with visual impairment face barriers in cash transactions, particularly in identifying banknote denominations and verifying authenticity, which can reduce independence and increase vulnerability to fraud. This issue is also closely linked to the financial inclusion agenda, as access to reliable information on the value and authenticity of cash is a prerequisite for safe transactions among vulnerable groups. This community service program aimed to improve users’ competence through individualized, home-visit–based education and mentoring on an optical–UV sensor–based banknote denomination and authenticity detector with audio feedback. The program was implemented in collaboration with the Kebumen branches of PERTUNI and ITMI from October to December 2025. The intervention stages included an initial needs assessment, structured training using a concise module, hands-on practice through transaction scenarios, and follow-up mentoring. Evaluation employed a pre–post knowledge test, a practical performance checklist, and a usability questionnaire. Results indicated that the mean knowledge score increased from 55.1 to 80.7, and the success rate of denomination identification improved from 60.7% to 90.0%. This approach is relevant as an individualized mentoring model for blind communities when group-based training is difficult to implement.

Children with special needs require specialized educational services that accommodate their diverse learning characteristics, and digital-based media offers flexible and adaptive learning opportunities tailored to individual abilities. The digital learning media “Voca Poly” was developed to provide education and practical skills training for blind and physically disabled children, particularly in strengthening knowledge and cooking skills to support independent living. This community service program was implemented through three main stages: preparation, implementation, and evaluation. The preparation stage involved needs assessment, media design, and coordination with partner institutions. The implementation stage included interactive learning sessions using the Voca Poly educational game, focusing on food security concepts through English vocabulary from planting to food processing. The evaluation stage assessed participants’ understanding, engagement, and skill improvement. The results showed increased knowledge of cooking concepts and improved practical skills among participants. Moreover, the game-based approach successfully fostered enthusiasm, motivation, and active participation among visually impaired and physically disabled children.

People with disabilities, especially the blind, still face various structural and cultural barriers that impact their psychological well-being and ability to participate in social life. Resilience is an important aspect that enables blind individuals to recover from pressure, stigma, and environmental limitations. This study aims to understand the role of the Sahabat Mata Community in shaping the resilience of its members. This study is a qualitative study using a phenomenological approach involving three subjects, namely members and administrators of the Sahabat Mata Community (KSM). Data collection methods were carried out through semi-structured interviews, participant observation, and document studies. The results of the study indicate that the Sahabat Mata Community (KSM) has contributed to the resilience of its members based on seven aspects of resilience according to Reivich & Shatte including emotional regulation, impulse control, optimism, problem-analyzing ability, self-efficacy, empathy, and achievement. The formation of resilience is strengthened through social processes, emotional support and opportunities to achieve self-potential formed in the Sahabat Mata Community. The findings of this study reveal that the Sahabat Mata Community as an inclusive community plays a role as a safe space for the formation of resilience of people with disabilities.

The toilet training program for blind students at the State Special School (SKhN) 01 Pandegelang is an important aspect in the development of basic life skills. Blind students need to be trained systematically and continuously. This study used a qualitative approach. Data collection techniques were carried out through observation, in-depth interviews with teachers, students and parents, and documentation of the learning program implemented at the school. The results of the study indicate that the toilet training program at SKh Negeri 01 Pandegelang has been designed based on the individual needs of students, by implementing routine-based learning strategies, positive reinforcement, and the use of learning media that can be accessed tactilely and auditorily. Obstacles faced in the implementation of the program include limited special educators, lack of supporting facilities. Nevertheless, this program has a positive impact on increasing the independence of blind students in terms of personal hygiene, discipline, and self-confidence. The conclusion of this study shows that the success of the toilet training program is greatly influenced by teacher involvement, collaboration with parents, and adaptation of learning methods that are appropriate to the characteristics and needs of blind students. Researchers recommend strengthening teacher training, providing disability-friendly facilities, and regular program evaluations to improve optimal results

This research examines the paradox of Christian leader integrity in facing political polarization and group identity in Toraja society. The background of the problem is a contradictive phenomenon where Christian communities strongly emphasize ethical character of leaders, yet strong group identification can blind them to ethical inconsistencies of supported leaders, especially in the dynamics of regional and presidential elections that divide churches. This research aims to analyze the paradox of Christian leader integrity, identify psychological, theological, and sociological factors causing ethical blindness, and formulate leadership principles that can maintain integrity amid political pressure. Using qualitative descriptive methods based on literature study, this research collects data from leadership theology literature, group identity psychology, and empirical studies on political practices in Toraja Christian communities. Research findings show that the integrity paradox manifests in local political dynamics where ethical standards become loose when leaders come from the same identity group. Factors causing ethical blindness include in-group bias and cognitive dissonance (psychological), sacred-secular dualism and permissive interpretation (theological), as well as clan structure and conformity pressure (sociological). The formulated leadership principles include commitment to biblical standards, theology-based political education, transformative prophetic role, accountability systems, contextual leadership, and building mature faith communities. The implication is that this research provides theoretical contributions to the development of contextual leadership theology and practical recommendations for church leaders in navigating the complexity of identity politics. Research recommendations include developing theology-based political education programs in churches, building leadership accountability systems, and further empirical research to validate the conceptual framework that has been built.

This study investigates the influence of coffee brewing device branding on the sensory perception of coffee flavor at TEFA Javanica, Politeknik Negeri Banyuwangi. Focusing on three V60 dripper brands—Hario (Japanese brand), Indotara (local generic brand), and One Two Cup (local brand with English naming)—the research employs an experimental quantitative approach combining blind and branded taste tests. The blind test eliminates brand influence, allowing assessment of the inherent coffee taste, while the branded test examines how brand expectations affect flavor experience and consumer perception. Sensory evaluation follows the Specialty Coffee Association's standardized cupping protocol, assessing aroma, taste, aftertaste, balance, and overall impression. Data from 45 purposively selected experienced coffee tasters were analyzed using the McNemar test to statistically compare preferences between blind and branded conditions. Results show significant brand effects on consumer perception for two of the three brands tested, highlighting branding’s role in shaping sensory experience. These findings offer valuable insights for coffee producers and marketers to optimize brewing device selection and branding strategies, enhancing customer satisfaction and competitive positioning. Academically, the study enriches literature on sensory branding in coffee, emphasizing the importance of equipment branding in specialty coffee markets. This research also lays groundwork for future studies exploring marketing and consumer psychology aspects within the specialty coffee industry.

Non-communicable diseases (NCDs) are a major challenge in today's health development. One category of these diseases is hypertension, which is classified as a chronic disease with a relatively high mortality rate. Hypertension serves as a major predictor for various chronic diseases and is a common disease found in the community (Putri et al., 2025). If not managed properly, hypertension can lead to more serious complications such as stroke, coronary heart disease, diabetes, kidney failure, and blindness. Stroke (51%) and coronary heart disease (45%) are the leading causes of death related to hypertension (Pokhrel, 2024). The increasing prevalence of hypertension along with changes in lifestyle and unhealthy eating patterns adds to the global health burden. Therefore, effective management of hypertension is essential to prevent further complications. Appropriate hypertension management and regular monitoring can reduce the risk of related diseases, improve quality of life, and reduce mortality caused by complications of heart disease and stroke. Preventive and promotive efforts through health education are key to reducing the prevalence of hypertension in the community.

Tidaran 1 Hamlet, Candiretno Village, Magelang Regency, is a rural area with quite heavy traffic in several areas. One location of particular concern is the bends and T-junctions in RT 11, which are frequently used by both two-wheeled and four-wheeled vehicles. This area is known to be an accident-prone area due to blind spots that obstruct the view of drivers from both directions. Unfortunately, to date, there are no safety facilities such as traffic signs or convex mirrors to aid visibility. Seeing this problem, students participating in the Community Service Program (KKN) from Tidar University conducted an intervention based on community needs. One effort was the installation of convex mirrors to minimize the risk of accidents. This activity was carried out using an action research method (action research), which included field observation, risk analysis, solution design, implementation, and impact evaluation. Throughout the process, students actively involved the community, the RT head, and village officials to ensure the proposed solution was participatory and sustainable. Convex mirrors with a diameter of 80 cm and a 2.5-meter-high support pole were installed at strategic points on the bends. Following the installation, follow-up observations and interviews with local residents were conducted. The results showed a significant improvement in visibility for drivers, especially at night and in similar weather. Residents reported feeling safer, less hesitant when crossing, and more alert to oncoming traffic. This program not only improved safety but also raised public awareness of the importance of traffic management. Therefore, similar interventions can be replicated in other vulnerable areas, with collaborative support from the community, universities, and village government.

Rhegmatogenous retinal detachment is a condition in which the sensory retina separates from the retinal pigment epithelium due to a retinal tear that allows vitreous fluid to accumulate in the subretinal space. It is an ophthalmologic emergency that may result in permanent blindness if not managed promptly and appropriately. This case report aims to describe the clinical course, diagnosis, and management of a 62-year-old male patient who presented with sudden blurred vision in the right eye, accompanied by floaters, photopsia, and discomfort. The patient had a history of bilateral cataracts and underwent vitrectomy. Data were collected from medical records and supporting examinations, confirming the diagnosis of rhegmatogenous retinal detachment. Management included topical therapy, systemic medication, bed rest, and surgical intervention. Clinical improvement was observed postoperatively. This report highlights the importance of early detection and timely treatment to preserve visual function.  

This study aims to obtain data on the music learning process using the Learning By Doing method with the melodica as a musical instrument for visually impaired sixth-grade students at SLB-A Pembina Tingkat Nasional (Special School for the Blind). Learning By Doing emphasizes the active involvement of students in the learning process. This is particularly relevant for visually impaired students, as they rely more heavily on their sense of hearing and touch to receive information. To gain a clear understanding of the stages of music learning using this method, the researcher employed a descriptive approach. Several data collection techniques were used, including interviews, observation of learning activities, document analysis, and field notes. The study was conducted over the course of one semester. The results of the research show that the implementation of the Learning By Doing method in music education involves three main stages: the planning stage (lesson plans and syllabus), the implementation stage (interactive learning and hands-on practice), and the evaluation stage. The application of Learning By Doing increased student engagement and understanding of basic musical tone concepts, and also supported their musical skills, auditory abilities, and experience in recognizing expression through sound. Thus, the Learning By Doing method is effective in teaching music to visually impaired students because it provides a concrete and meaningful learning experience.

Youtube social media is still one of the forms of communication media that is widely used in society, which of course there are many speech acts that follow it. This research is motivated by the relationship between communication in society which is accompanied by the many illocutionary speech acts used by people in videos uploaded on Youtube social media. In addition, this study aims to describe the illocutionary speech acts in the video "Becoming Blind in a Day" from the Froyonion Youtube channel and its suitability as teaching materials for learning response texts. This study is a type of qualitative descriptive research. The source of this research is the video "Becoming Blind in a Day" from the Froyonion Youtube channel which was uploaded on January 31, 2020. The data in this study are transcripts of speech in the form of sentences that indicate the presence of illocutionary speech acts in the video "Becoming Blind in a Day" from the Froyonion Youtube channel. The data collection techniques used by the author are listening techniques and note-taking techniques. The analysis technique used is to transcribe the audio on the video into written form, identify and analyze the form of speech, and make a conclusion regarding the illocutionary speech act, as well as a conclusion on its suitability as a teaching material for learning response texts in the video "Becoming Blind in a Day" from the Froyonion Youtube channel. The results of this study indicate the presence of five types of illocutionary speech acts in the video with the percentage of the amount of data obtained (a) 24.4% representative, (b) 37.9% directive, (c) 3.4% commissive, (d) 34.6% expressive, and (e) 1.7% declarative. The results of the analysis of speech acts in the video "Becoming Blind in a Day" from the Froyonion Youtube channel are suitable for use as teaching materials for learning response texts in line with the CP (Learning Achievements) in the reading and viewing elements in the Merdeka Curriculum. From this study, it is hoped that it can be used as teaching materials for learning response texts and also as a reference for various language activities. 

High blood pressure is a problem that is widely suffered by the community, especially in Indonesia. Hypertension that is not detected early and treated properly can trigger coronary heart disease, heart failure, stroke, chronic kidney failure, blindness due to hypertensive retinopathy and peripheral arterial disease. The purpose of community service is to lower blood pressure in people with hypertension. It is hoped that through this activity it will be a source of information to increase the knowledge of people with hypertension about finger grip gymnastics techniques to lower blood pressure. The implementation method in this community service is to carry out finger grip gymnastics activities and before the activity, blood pressure measurements are carried out. This community service activity was carried out on people with hypertension aged >40 years as many as 36 elderly people at the Posyandu, Bogoarum Village, Plaosan District, Magetan Regency, East Java Province. The results of the blood pressure of people with hypertension who participated in finger grip gymnastics obtained pretest blood pressure with a mean blood pressure value of 157.78 / 92.22 mmhg. While the posttest blood pressure with a mean blood pressure value of 145 / 83.3 mmhg. It was concluded that there was a decrease between the pretest and posttest blood pressure values. This service is expected to be a preventive recommendation that can be given to hypertension sufferers, namely so that the community remains active in participating in finger grip gymnastics activities that can be done routinely at the integrated health post so that it can reduce the number of hypertension complications.

In the past, toys were identified solely as instruments of entertainment for children. Adults were generally considered inappropriate to own or play with toys. Over time, toys have evolved into collectibles that have artistic, historical, and investment value for people of all ages. This study aims to analyze Pop Mart's marketing strategy in shaping impulsive buying behavior. The study was conducted using descriptive qualitative methods. The research data was obtained from digital searches and observations from various official sources and related official websites. The results of the study show that Pop Mart, as a leader in this industry, has successfully implemented marketing strategies that utilize collaborations with artists, the blind box concept, and the principle of scarcity to create a unique and attractive shopping experience for its consumers. Collaborations with artists play an important role in building brand identity and increasing product appeal. By offering limited editions of popular characters such as Molly, Labubu, and SkullPanda, Pop Mart has been able to attract collectors and art enthusiasts who have an emotional connection to these works. This has led to increased brand loyalty and purchase frequency. The blind box concept creates an element of surprise that triggers excitement when opening the packaging, thereby encouraging repeat purchases. Additionally, the scarcity marketing strategy, combined with the application of FOMO behavior, successfully creates a sense of urgency among consumers. Products with limited editions and purchase quantity restrictions create exclusivity, making consumers feel they must act quickly to obtain the product before it sells out.

Diabetic retinopathy is a microvascular complication that often occurs in people with type 2 diabetes mellitus and is a major cause of blindness in older adults and the elderly. This study aims to describe the characteristics of diabetic retinopathy in people with type 2 diabetes mellitus through a literature review of 10 journals published between 2022 and 2025. The results of the analysis show that the prevalence of diabetic retinopathy globally reaches 35%, with the main risk factors including long duration of diabetes (>5 years), high HbA1c levels (>7%), and poor glycemic control. The majority of cases of diabetic retinopathy are found in the non-proliferative stage (65%), which is characterized by microaneurysms and retinal hemorrhages, while the proliferative stage is less common but has a high risk of causing blindness. The study also revealed that patients with comorbidities such as hypertension and dyslipidemia tend to experience more severe diabetic retinopathy. Further stages of diabetic retinopathy if not managed properly can cause vision-threatening conditions. However, low patient compliance in metabolic control and eye examination is a major challenge. Management of diabetic retinopathy requires a holistic approach that includes patient education, regular screening, and comprehensive risk factor control to prevent progression of diabetic retinopathy and maintain the quality of life of patients with type 2 diabetes mellitus.

This paper examines the life struggles of Javed Khan, a second-generation Pakistani immigrant in the United Kingdom in Blinded by Light film. Culturally, as a Pakistani-British, Javed lives in two worlds, i.e., the old world belonging to his parents and his current world, the world he is living in, i.e., the British society and culture. To analyze this topic, the textual content analysis is employed. As for the theoretical framework, Hall’s concept of identity and some works of literature on discrimination are of importance. The result of the analysis shows that Javed’s journey reveals the challenges and pressures of adaptation and acculturation faced by second-generation immigrants in general, illustrating how the tension between intergenerational expectations often creates tension and fosters growth and understanding in a multicultural context. Javed is torn between the values of the home country his father holds and the values of the new country. In addition, the discrimination experienced by Malik Khan’s family reflects the experience of immigrant families in a broader context. The film encourages viewers to reflect on the societal expectations of immigrants to conform to the host society and culture, while also showcasing the importance of individual aspirations and self-expression.  

This research aims to find out what parenting models for parents with children with visual disabilities can be applied. This research uses a qualitative approach with a literature study approach through journals, books, and previous research. The result of the research is that children with visual disabilities have different parenting patterns from parents with other disabilities or non-disabilities. Children with visual disabilities must be given the best during their golden age and after that period give confidence and independence to children, after adolescence children have friends and parents must recognize and control children's friendships so as not to fall into something wrong, when children with visual disabilities grow up parents help children to be able to make the best decisions for themselves until children can make rational decisions and with mature thinking.

This study examined the effect of using Blind Map media on student learning outcomes in Social Science subjects at State 46 Pekanbaru Junior High School. Due to the low level of achievement and understanding of the material, this study used a quantitative experimental approach. Approximately 80 seventh grade students were purposively identified, with grades E and D as the experimental and control groups respectively. The results showed that there was a significant effect of the Blind Map media on learning outcomes, with t observation = 24.670 > t table = 0.304 and t observation = 24.670 > t table = 0.304, indicating the rejection of H₀. The effect size of 2.859 indicates a slow rate of change, suggesting that increased use of the Blind Map media can improve student learning outcomes.
