The Frankfurt School represents one of the most influential traditions of critical thought in the development of twentieth-century social theory and philosophy. This article aims to examine the impact of Frankfurt School thought particularly the ideas of key figures such as Max Horkheimer, Theodor W. Adorno, Herbert Marcuse, and Jürgen Habermas and to analyze the relevance of their ideas within contemporary social contexts. Using a qualitative approach through an extensive literature review, this study examines key concepts such as critical theory, instrumental rationality, and the culture industry, as well as their implications for power relations, advanced capitalism, mass media, and modern democracy. The findings demonstrate that the Frankfurt School’s critique of instrumental rationality and cultural commodification remains highly relevant for understanding contemporary social problems, including digital media dominance, consumerism, and the crisis of the public sphere. This article argues that Frankfurt School thought continues to provide an essential analytical framework for critically engaging with the contradictions of modern and postmodern societies in the era of globalization and digital technology.

This research has a crucial objective to facilitate primary school (SD) teachers so they are able to effectively and efficiently integrate and present Social Studies (IPS) material enriched with the content of local wisdom. Local wisdom is defined as a treasure inherited through generations, encompassing in-depth knowledge, real practices, and fundamental values that have developed and been firmly held within the local community. This foundation makes the learning process not only informative but also highly relevant and meaningful for students’ lives. This article specifically highlights that the integration of values, culture, and knowledge sourced from the local area can produce significant positive impacts. These impacts include improving students' conceptual understanding of Social Studies material, fostering their active participation in the classroom, and honing essential critical thinking skills. Teachers are encouraged to use a contextual approach or a real-life-based approach, so the material taught feels close to the students' experiences and is easier to grasp. The values embedded in local wisdom will function as a strong bridge in understanding every material concept. Thus, the knowledge acquired by students does not only stop at the cognitive level (merely theoretical knowledge), but can also be implemented concretely in the form of real actions and behavior outside the school environment. This local wisdom-based learning approach will ultimately become an important connection that guides students to act appropriately, ethically, and solution-oriented in responding to various problems they face in their daily lives.

Adolescent mental health is an essential component of optimal growth and development, yet it often receives less attention compared to academic achievement. Adolescents are in a vulnerable developmental stage characterized by emotional changes, social pressure, and environmental demands, which increase the risk of mental health problems. This activity aimed to improve knowledge and promote positive attitudes among junior high school students regarding adolescent mental health, including its definition, signs and symptoms, risk factors, and prevention strategies. The method used was a health education intervention employing a pre-test and post-test design. The activity was conducted at Al Amanah Junior High School, South Tangerang City, involving 25 students. The evaluation instrument consisted of a 10-item multiple-choice questionnaire with a maximum score of 100. The results showed that the average pre-test score was 98.40%, while the post-test score increased to 99.60%, indicating a 1.20% improvement. Although the increase was relatively small due to the high baseline knowledge (ceiling effect), the findings demonstrate that the educational intervention effectively reinforced students’ understanding of adolescent mental health. In addition, interactive discussions during the session contributed to increased awareness and reduced stigma related to mental health issues. This mental health education program has the potential to support early prevention efforts and foster a more supportive school environment for adolescents’ psychological well-being.

Learning is the process of children getting to know knowledge that aims to increase knowledge as a basis for forming behavior. The learning process is carried out so that children experience behavioral changes and gain an overall improvement in knowledge, skills, and attitudes. Learning is very closely related to daily life, therefore it is important for children to learn continuously, one of which is through learning mathematics. Mathematics learning has a very important role in the sustainability of children's education because mathematics is one of the fundamental non-physical tools in the world of education and daily life. Through mathematics learning, children are trained to think logically, systematically, critically, and creatively in solving various problems. In addition, mathematics helps children solve calculation problems that are often encountered in daily activities, such as counting money, measuring length, time, and distance, and interpreting simple data. Mathematics learning also plays a role in developing the ability to reason and make appropriate decisions. Therefore, mathematics learning is a subject that must be followed because it has a great influence on thinking skills, learning independence, and children's readiness to face life challenges and scientific development in the future.

Continuous chemical control of rat pests (Rattus spp.) can sometimes lead to resistance and resurgence problems, and even some cases of inaccurate targeting ultimately killing livestock. The idea of ​​​​repelling rats in rice fields using vibrations of crickets and other natural animals transmitted via radio has been done and the results are quite optimal for rat control, but it has not been done in corn cultivation. The purpose of this study was to determine the effect of cat sound audio on the intensity of rat pest attacks (Rattus spp.) in corn (Zea mays L.) plantations. The research location was in a farmer's land owned by a farmer in Dagan Village, Solokuro District, Lamongan Regency. Determination of sampling points using the diagonal method, each into 5 sub-observation plots. In each sub-plot, markers were placed as sampling points. Audio with cat and bird sounds was played continuously from 05.00 pm - 07.00 am. Observations were conducted at 7:00 a.m. at all sampling points at 30 and 60 days after planting. Observations were conducted for three days using audio and three days without audio. Damage symptoms were observed directly at each sampling point. Corn plants showing symptoms were then recorded and analyzed using the Damage Intensity formula. Observations showed that the use of cat sound audio was able to reduce the level of rat infestation. At 30 days after planting, the damage percentage was reduced by 8.33%. Meanwhile, at 60 days after planting, the damage percentage was reduced by 18.33%.

This research focuses on the design and evaluation of a novel parallel graph optimization algorithm incorporating dynamic load balancing (DLB) to address inefficiencies in heterogeneous computing environments. Large-scale graph optimization problems, such as those in social networks, bioinformatics, and transportation systems, often suffer from computational imbalances when using traditional static load balancing approaches, leading to underutilized resources and prolonged execution times. The primary objective of this research is to develop an algorithm that can dynamically adjust workload distribution across processors, enhancing computational efficiency and scalability. The proposed method combines heuristic techniques, including region expansion and multilevel partitioning, with diffusive load balancing strategies to minimize inter-processor communication overhead. Experimental results demonstrate that the proposed algorithm reduces execution time by up to 40% compared to static methods, with optimized resource utilization and more balanced workload distribution. The scalability of the algorithm is also evident, as it adapts effectively to increasing problem sizes and processor counts. These findings suggest that dynamic load balancing is crucial for improving parallel graph optimization in real-world applications. Future work will focus on further enhancing the algorithm’s responsiveness to rapidly changing workloads and expanding its applicability to additional domains.

Overall, this outreach program effectively fostered entrepreneurial spirit, motivation, and readiness among students at SMK Ganesha Tama Boyolali to pursue independent business opportunities after graduation.

Production planning and inventory control are critical aspects of operations management, as they directly influence cost efficiency, resource utilization, and the continuity of the production process. Ineffective planning and inventory decisions may lead to excessive costs, production delays, or imbalances between supply and demand. The complexity of these problems, which often involve multi-period horizons and multi-stage decision-making processes, has encouraged the application of quantitative optimization methods, one of which is dynamic programming. This study aims to analyze and synthesize the application of dynamic programming in production planning and inventory control through a Systematic Literature Review (SLR) approach. The SLR process was conducted by systematically identifying, selecting, and analyzing 15 relevant national journal articles published between 2015 and 2024 and obtained from various recognized scientific databases. The reviewed literature indicates that dynamic programming is effective in supporting optimal decision-making by determining appropriate production quantities and inventory levels, minimizing total production and holding costs, and managing fluctuating demand conditions. In addition, this method helps reduce the risks associated with overstock and stockouts by considering sequential decision structures. However, the findings also reveal several limitations of dynamic programming, including high computational complexity, strong dependence on deterministic data assumptions, and limited flexibility in handling high levels of uncertainty. These constraints suggest the need for further methodological development or integration with other approaches to enhance practical applicability.

Malnutrition in children remains a serious public health challenge in Indonesia because it directly impacts growth, cognitive development, and the child's future quality of life. Parents play a crucial role in maintaining children's health, particularly in providing balanced nutrition and preventing nutritional problems such as stunting and malnutrition. This study aims to analyze the role of parents in maintaining children's health due to malnutrition based on a literature review. The method used is a qualitative literature study, through a search of various written sources in the form of scientific journals, articles, and relevant books obtained from Google Scholar. The results of the study indicate that the level of knowledge, education, parenting patterns, socioeconomic conditions, and active involvement of parents in monitoring children's growth significantly influence children's nutritional status and health. Parents play a role as providers of nutritious food, nutrition educators, role models of healthy lifestyles, and regular monitors of children's growth and development. Parents' lack of understanding of balanced nutrition, the habit of consuming instant foods, and minimal participation in health programs are risk factors for malnutrition in children. Therefore, increasing parental education and involvement through a family-based approach is an important strategy in efforts to prevent and address child nutrition problems sustainably.

Acne (Acne vulgaris) is one of the most common skin problems, affecting 80–85% of adolescents aged 15–18 years, with some cases persisting into adulthood. One of the associated bacteria is Staphylococcus epidermidis, a normal skin flora that can become an opportunistic pathogen. Bay leaves (Syzygium polyanthum) are known to contain secondary metabolites such as alkaloids, flavonoids, tannins, saponins, and essential oils with antibacterial activity. This study aimed to formulate ethanol extract of bay leaves into ointments with concentrations of 10%, 20%, and 30%, test their antibacterial activity against Staphylococcus epidermidis using the disc diffusion method, and evaluate their physical quality (organoleptic properties, homogeneity, pH, adhesion, and spreadability). Results showed that the ethanol extract of bay leaves contained alkaloids, flavonoids, saponins, and tannins. The ointments met topical quality standards with pH 5.8–6.9, adhesion time 36–41 seconds, and spreadability 6.9–8.1 cm. Antibacterial activity increased with higher concentrations: 7.8 mm (10%), 12 mm (20%), and 15 mm (30%), although still lower than the positive control (clindamycin, 34 mm). In conclusion, ethanol extract of bay leaves has potential as an active ingredient in topical anti-acne ointments, but further studies with higher concentrations, in vivo testing, and optimized formulations are needed to achieve efficacy comparable to synthetic antibiotics.  

This community service programme was implemented in the coastal community of Padelegan Village, Pademawu Subdistrict, Pamekasan Regency, with a focus on strengthening health literacy and behaviour-based disease prevention at the household level. The background of the activity is based on the vulnerability of coastal communities to health problems related to hygiene, household drinking water management, and environmental cleanliness, as well as the need for an approach that not only increases knowledge but also encourages consistent preventive practices. The programme aims to improve residents' ability to understand and use health information in an applicable manner, while strengthening key disease prevention behaviours through education and mentoring. The activity will be carried out from February to April 2025 with a behaviour-based education design combined with practice demonstrations and community mentoring, involving 48 participants (40 residents/households and 8 posyandu/PKK cadres). The stages included initial assessment, development of KIE media (brief modules and leaflets/posters), two education-demonstration sessions, two home mentoring sessions, and final evaluation. The evaluation was conducted using pre-post knowledge, attitude, and practice (KAP) assessments and practice observation through a checklist. The results showed an increase in health literacy and improved consistency in preventive behaviour; knowledge increased from 5.4 to 7.8, and compliance with hand washing at critical times increased from 41.7% to 72.9%. Programme outputs included an information, education and communication (IEC) package, a household monitoring checklist, and capacity building for cadres as local facilitators. It was concluded that the integration of participatory education, practical demonstrations and cadre mentoring has the potential to be effective in encouraging preventive behavioural change in coastal communities, with recommendations for integrating monitoring into the routine agenda of integrated health service posts (posyandu) and community empowerment groups (PKK) and for follow-up monitoring for 3–6 months to maintain the sustainability of practices.

Adolescents are an age group that is vulnerable to reproductive health problems, including the risk of Sexually Transmitted Infections (STIs) and risky sexual behaviors, due to limited knowledge and psychosocial maturity. Schools have a strategic role in providing reproductive health education as a promotive and preventive effort. This counseling activity aimed to determine adolescents’ knowledge regarding the prevention of Sexually Transmitted Infections (STIs) among students at Parulian 3 School, Medan.This study employed a one-group pretest–posttest approach. The participants were all seventh-grade students who met the inclusion criteria. The intervention consisted of reproductive health education delivered through lectures, discussions, and visual media. Data were collected using questionnaires measuring knowledge and attitudes before and after the counseling session, and then analyzed descriptively by comparing pretest and posttest results. The results showed an increase in students’ knowledge and attitudes after receiving reproductive health education. The differences in scores before and after the intervention indicate that the counseling provided was effective in improving students’ understanding and fostering positive attitudes toward the prevention of STIs and risky sexual behaviors. Reproductive health education in the school setting is an effective effort to enhance adolescents’ knowledge and attitudes regarding reproductive health. Therefore, reproductive health education activities should be implemented continuously and integrated into school programs.
