Ineffective management of household waste in rural areas, such as Aek Korsik Village, Aek Ledong District, Asahan Regency, causes air pollution due to traditional waste burning practices. This research aims to design and implement an environmentally friendly low-smoke waste incinerator as an alternative solution based on simple technology and local resources. The research methods used are technological engineering approaches and field studies, including tool design, trials, and environmental and social impact evaluation. The furnace is designed using heat-resistant local materials and mild steel, features a dual ventilation system and a smoke exhaust system with a simple filter, and has a combustion capacity of 5 kilograms per cycle. Preliminary studies show that the composition of waste is dominated by organic matter (60%), plastic and paper (30%), as well as the rest are inorganic. Testing over several weeks showed that an average burn time of 1.5 hours was able to reduce smoke emissions by up to 60% compared to conventional methods. The air quality around the test site has improved significantly, and the community has responded positively to the ease of use and environmental benefits of the furnace. This study concludes that low-smoke combustion furnaces are effective as environmentally friendly waste management solutions in villages, with recommendations for increasing combustion capacity and integrating other waste management methods to support sustainability and environmental preservation.

Bronchial asthma is a chronic inflammatory disease of the airways that is often triggered by exposure to cigarette smoke, both active and passive. This exposure contains harmful substances such as nicotine, tar, and carbon monoxide that can irritate the airways, increase inflammation, and worsen asthma symptoms. This study aims to determine the relationship between cigarette smoke exposure and the incidence of bronchial asthma in patients at the Pulmonary Polyclinic of Dr. H. Moch. Ansari Saleh Regional General Hospital, Banjarmasin. The research method used a quantitative approach with a cross-sectional design. A sample of 47 patients was selected through purposive sampling according to the inclusion criteria. Data were collected through questionnaires and medical records, then analyzed using the Chi-Square test (α = 0.05). The results showed that the majority of respondents were passive smokers (61.70%), had family members who smoked (57.45%), and were exposed to cigarette smoke daily (55.32%). All respondents had been diagnosed with asthma by medical personnel, and 91.49% reported worsening symptoms after exposure to cigarette smoke. The chi-square test results showed a significant association between cigarette smoke exposure and the incidence of bronchial asthma (p = 0.026). This finding confirms that cigarette smoke exposure is an important risk factor that must be avoided to prevent relapse and worsening of asthma. Therefore, patient and family education regarding the dangers of cigarette smoke, the implementation of smoke-free areas, environmental support, and smoking cessation programs need to be continuously improved as strategies for controlling bronchial asthma.

Well water is still one of the main sources of daily water supply for the residents of the Candi Muaro Jambi area. The dependence on well water makes it vital for consumption, cooking, and other domestic activities. However, with the increasing human activity, the development of tourist areas, and environmental changes in the surrounding area, the quality of the well water is at risk of being affected. This study aims to evaluate the feasibility of well water from an environmental and health perspective based on physical, chemical, and biological parameters, referring to the clean water quality standards set by the Ministry of Health of the Republic of Indonesia. The research employs a descriptive quantitative method, with well water samples taken from several points around the residential areas in the Candi Muaro Jambi region. The analyzed parameters include temperature, color, odor, turbidity, pH, nitrate content, metal content (Fe and Mn), and the presence of coliform bacteria. Laboratory test results show that most of the well water samples still meet the established physical and chemical standards, but some wells were found to have coliform levels exceeding the recommended threshold. This condition indicates contamination, most likely from domestic waste, particularly from household sanitation systems that are not ideally located relative to the wells. While the well water in the study area is generally still suitable for daily use, it is recommended that the community performs simple water treatment, such as boiling or filtration, before direct consumption. These measures are crucial to reduce contamination risks and ensure the water's quality for safe consumption and health.

This study explores the metaphor of life in Colleen Hoover’s novel Reminders of Him, aiming to identify the types of linguistic metaphors and analyze the conceptual metaphors that underlie them. Based on Lakoff and Johnson’s conceptual metaphor theory, which classifies metaphors into structural, ontological, and orientational categories, this study highlights the role of metaphor as a cognitive tool, not merely a stylistic device. A qualitative method was employed, with data collected using AntConc software by focusing on parts of the novel containing the word “life.” The Metaphor Identification Procedure was applied to identify linguistic metaphors, which were then categorized based on the word class of the lexical units that were used metaphorically. The results of this study show four types of linguistic metaphors involving the noun “life”: nominal, verbal, adjectival, and prepositional. These forms portray life as a physical object, a process, a possessed attribute, or a container. These linguistic metaphors reflect eight conceptual metaphors, including five ontological metaphors (life is ownership, life is a container, life is an entity, life is air, life is a place) and three structural metaphors (life is a machine, life is a journey, life is a challenge). The diversity of these conceptual metaphors illustrates the rich representation of life in the novel.  

The problem of plastic waste in Gandan Hamlet, Pogalan Village, is becoming an increasingly urgent environmental issue that requires sustainable management. Unmanaged waste can pollute the soil, air, and water, and threaten public health. In response to this situation, Tidar University Community Service (KKN) students implemented an innovative community-based waste management program. The main focus of this program is to utilize plastic waste into products with utility and sales value, namely plastic-filled pillows and Eco-Paving Blocks. This activity was carried out through a participatory approach by actively involving the community at every stage, from outreach and education to technical training on the collection, sorting, and processing of plastic waste. The education provided concerns the dangers of plastic waste to the environment and the importance of recycling as an alternative solution. Making pillows from plastic filling was chosen because the process is simple, inexpensive, and can be done by housewives. Meanwhile, Eco-Paving Blocks are the result of utilizing mixed plastic waste as an environmentally friendly and durable building material. This program has succeeded in reducing the volume of plastic waste in the surrounding environment, while raising public awareness of the importance of environmental conservation. Furthermore, this activity opens up new economic opportunities for the community by creating creative products from waste. Evaluation results show that the community-based waste management model is effective in fostering community independence in waste processing, creating a cleaner environment, and encouraging a culture of sustainable living at the village level. The success of this program is expected to serve as an example for replication in other areas with similar challenges. Continued support from the village government and cross-sector collaboration are key to this initiative's continued growth and long-term impact.

Dysmenorrhea is pain that occurs before, after, or during menstruation. The occurrence of dysmenorrhea in adolescents, especially college students, often hinders the activities that these students must perform and can lead to diseases of the reproductive system. However, dysmenorrhea is often considered a common disease, and its effects are not well understood. This study aims to analyze the effect of education using flashcards related to high calcium and magnesium diets, as well as exercise, on the severity of dysmenorrhea and knowledge levels among health and non-health students at Airlangga University. The method used in this study is experimental with a Quasi-Experimental design and a pretest-posttest control group design among health and non-health students at Airlangga University. The instruments used in this study include questionnaires, flashcards, and a recipe book. The results of this study indicate significant changes in knowledge before and after education, and significant differences in knowledge between the treatment group and the control group. The conclusion of this study is that education using flash cards can be used to improve knowledge and behavior in both groups, both health and non-health students. Therefore, it is recommended that universities conduct regular education programs related to diseases that are still underestimated by the general public

Waste management remains a significant challenge in Dusun Balinappang, Desa Bontoramba, Kecamatan Pallangga, Kabupaten Gowa, Makassar City. Low community awareness regarding waste sorting and proper management has led to a decline in environmental health quality. Improper waste management can result in various environmental problems, such as water, soil, and air pollution. To address this issue, a community service activity was conducted with the aim of improving public knowledge and awareness on proper waste management through the 3R approach (Reduce, Reuse, Recycle). The method used for this activity involved education through the use of posters. The posters were designed to be visually engaging and simple, making them easy for the community to understand. This visual medium effectively conveyed information about the importance of waste sorting and applying the 3R principles. Additionally, pre-tests and post-tests were used as evaluations to measure the change in participants’ knowledge before and after receiving the education. The pre-test was conducted to assess participants' initial understanding, while the post-test helped determine the extent of their knowledge improvement regarding 3R concepts and waste management practices. The results of the activity showed a significant increase in the community’s understanding of 3R principles and proper waste management techniques. The community began to demonstrate positive behavior changes, such as sorting household waste more carefully and reusing materials that could be recycled. This shift contributed positively to raising environmental awareness and improving the health of the local community. With this simple yet effective education, it is hoped that the program can continue and be expanded to other areas. This initiative will contribute to creating a cleaner, healthier, and more sustainable environment, which will have a long-term positive impact on the quality of life for the community.

Tropical forests play an important role as carbon sinks and biomass stores, including through the litter produced by vegetation. Litter contributes to nutrient cycling, maintains soil fertility, and is an important component of ecosystem carbon reserves. This study aims to estimate the biomass and carbon content of litter in the Jaboi Hot Spring Flow Area, Sukajaya District, Sabang City. The study was conducted in June 2025 using a 100 m long line transect method with four transects, each consisting of 18 1 x 1 m plots. Leaf litter samples were collected, their wet weight was measured, dried in an oven for 48 hours, and their carbon content was calculated based on the percentage of organic carbon of 0.47. The results showed a total litter biomass of 8,106 kg/m² with an average of 2,027 kg/m², and a total litter carbon of 3,809 kg/m² with an average of 0,952 kg/m². The highest values were found at Station 3 (2,354 kg/m² and 1,106 kg/m²) and the lowest at Station 1 (1,691 kg/m² and 0,795 kg/m²). Variations in values are influenced by soil physical-chemical factors, vegetation density, and climatic conditions, which influence production and decomposition rates. These results emphasize the importance of monitoring biomass and litter carbon to support forest management and conservation.

Hypertension is a global health problem whose prevalence continues to increase every year. This condition is not only a major cause of cardiovascular disease but also contributes to high morbidity and mortality rates in various countries, including Indonesia. One risk factor mitigating this problem is low public awareness of the importance of routine blood pressure monitoring. Therefore, promotive and preventive efforts are needed through health education that is easy to understand and can be applied in everyday life. This community service activity aims to increase public knowledge, especially among the elderly, about hypertension and the application of simple non-pharmacological therapies. One method introduced is soaking feet in warm water with added salt. This method is considered safe, practical, and cost-effective, making it suitable for elderly people in rural communities. The activity was carried out in Mauleng Hamlet, Paccing Village, Awangpone District, Bone Regency, with 15 elderly participants. The activity method included a pre-test to determine the participants' initial level of knowledge, counseling on hypertension, direct compression using warm water and salt foot soaks, and a post-test to measure knowledge improvement. The results showed a significant increase in participants' level of knowledge. Prior to the outreach program, only 7% of respondents had sufficient knowledge about hypertension and non-pharmacological therapy. After the outreach and reinforcement program, this figure increased to 87%. These results indicate that health education combined with practical demonstrations is highly effective in increasing public knowledge. Therefore, it can be concluded that educational activities and warm salt foot soak therapy have proven effective in increasing public understanding of non-pharmacological hypertension management and have the potential for widespread implementation as a health promotion measure.

Shrub vegetation is an important component in the structure of vegetation communities that have a significant ecological role, especially in maintaining soil stability and supporting biodiversity. One area that has the potential for shrub vegetation diversity but has not been scientifically documented is the Jaboi hot spring area, Weh Island, Sukajaya District, Sabang City. The purpose of this study was to investigate various types of shrub vegetation found in the study area and to calculate the diversity index. Data collection was carried out using a one-hundred-meter line transect method divided into four paths, with one pair of transects directed towards residential areas and plantation areas, while the remaining two transects were directed towards areas that were still forested. At each transect there were six observation points with a distance between points of 20 meters, each point consisting of three quadrat plots measuring 2 × 2 meters. Analysis of the diversity index used the Shannon-Wiener formula (H’). The results showed that there were 9 shrub species from 7 families with a total of 169 individuals from four observation stations. The Melastomataceae family dominates the shrub community with two main species, Melastoma malabathricum and Memecylon caeruleum. The diversity index value is 2.17, which is included in the moderate category (H = 2–3). This diversity is influenced by the physical-chemical conditions of the environment, such as acidic soil pH (4.4–5.5) and relatively stable temperatures, although temperatures exceeding the optimum limit were found in some locations. This study provides initial data on the potential of shrub vegetation as a basis for ecosystem management and conservation in the area.

The presence of scattered waste in the environment has a significant impact on both environmental sustainability and human health. In Indonesia, the accumulation of waste has reached alarming levels, amounting to approximately 175,000 tons per day, or the equivalent of 64 million tons annually. Household activities are one of the main contributors, producing a wide variety of waste, including organic and non-organic materials. Poto Village is among the areas receiving particular attention regarding this issue due to the challenges it faces in waste management. Improper management of waste not only leads to air, water, and soil pollution but also increases the risk of various health problems within the community. One of the programs designed to address this problem is the 3R program, which emphasizes three main principles: reduce, recycle, and reuse. The purpose of this community service initiative is to improve public knowledge and awareness of effective waste management through the application of 3R practices. The activities were carried out in three main stages, namely preparation, education, and discussion through a question-and-answer session. The process began with a socialization activity that introduced the objectives, purposes, and sustainability aspects of waste management efforts in the village. The educational session was attended by 30 participants, consisting of housewives, farmers, and entrepreneurs, who represented key groups within the community. Furthermore, interviews with local cadres revealed that waste is collected weekly by garbage trucks, indicating the village’s commitment to environmental management. Participants responded enthusiastically throughout the educational sessions, showing a strong interest and positive reception toward the information provided. As a follow-up step, future activities could include hands-on training in waste management using available media and tools, which would allow participants to apply the concepts learned in a practical and sustainable manner.

Tawangsari Hamlet, Tejosari Village, Ngablak District, Magelang Regency, faces serious waste management challenges, reflected in the high daily waste production and the inactivity of waste banks post-COVID-19. To address this issue, the Tidar University Community Service Program (KKN) was implemented, aiming to improve environmental cleanliness through active community participation. This program also supports the achievement of the "Climate Action" goal in the Sustainable Development Goals (SDGs), which focuses on combating climate change caused by air pollution and reducing environmental pollution. The method used in this program is Participatory Action Research (PAR), which is oriented towards community empowerment by involving all stakeholders in every stage of implementation. The activity began with a series of observations to understand the condition of waste management in the community. Then, a waste management tool was created in the form of a smoke-free waste incinerator, which aims to manage inorganic waste in an environmentally friendly manner. In addition, trash bins to facilitate waste sorting at the household level were also provided. Socialization and mentoring for the community, especially youth organizations, were carried out to introduce and educate them on the correct use of incinerators and waste sorting. A demonstration of incinerator use was also conducted with the community, which proved to increase understanding and active participation. The implementation of the incinerator and waste sorting facility demonstrated that these measures were effective in addressing the waste problem in Tawangsari Hamlet and contributed to a cleaner and healthier environment. Furthermore, the program successfully raised environmental awareness among the Tawangsari Hamlet community. Through direct involvement in the waste management process, residents not only gained new knowledge about the importance of waste sorting but also experienced the direct benefits of implementing smoke-free incinerator technology.Keywords: waste management, low-smoke incinerator, Climate Action, SDGs, community empowerment, environmental pollution, Magelang Regency

In general, attacks on hospitals are prohibited under international humanitarian law (IHL), which aims to protect the life and health of civilians during armed conflicts. However, in certain circumstances, hospitals may lose their protection and thus become legitimate targets in warfare if they are considered to be involved in military activities or supporting the parties to the conflict. This brings into question the application of the principle of proportionality, which is an essential element of IHL. The principle of proportionality seeks to balance military necessity with the protection of civilians, requiring that the harm caused by military operations should not be disproportionate to the military advantage sought. This principle demands that military operations be conducted carefully to minimize harm to civilians and civilian objects, including hospitals. However, its application raises significant ethical questions regarding the moral justification of such actions, especially when hospitals are targeted in attacks. One prominent example that raises ethical concerns about this justification is the destruction of Al-Shifa Hospital in Northern Gaza. The hospital was destroyed in an airstrike during the conflict, causing severe harm to the civilian population that relied on this facility. While the principle of proportionality is designed to limit damage, attacks on hospitals such as Al-Shifa raise questions about whether the actions taken were truly consistent with this principle, particularly when the military gain achieved does not seem to outweigh the damage caused to human life and vital infrastructure. This article aims to explore the conventional moral justification of the principle of proportionality in international humanitarian law and evaluate its application in the case of Al-Shifa Hospital, challenging the boundaries of the principle in practice.

This study aims to analyze the factors that affect passenger satisfaction at the airport through three main perspectives, namely: service, technology, and operations. The approach used is a literature study of ten scientific journals that discuss airport service quality from various aspects. The results of the study show that service quality, especially those covering SERVQUAL dimensions such as reliability, responsiveness, empathy, assurance, and physical evidence, plays a major role in shaping service user perceptions. The technology perspective, through the implementation of self-service such as self check-in, Flight Information Display Sistem (FIDS), and digital service applications, is proven to increase efficiency and convenience, even contributing up to 96.8% to user satisfaction according to one study. Meanwhile, from an operational perspective, aspects such as queue time at check-in counters, public facilities, and accessibility to the terminal also have a significant impact on the overall passenger experience. The conclusion of this study emphasizes the importance of integration between the three perspectives in designing strategies to improve airport service quality. Suggestions are given to airport managers to continue to improve services, expand technology adoption, and reorganize operations to create a safe, comfortable, and satisfying travel experience for all service users

Home industries are small- to medium-scale production units operated within or near households, typically relying on family members or a limited local workforce, with modest capital and without large-scale industrial technology. In furniture production, the main outputs are household items such as chairs, tables, wardrobes, beds, and shelves, while by-products include sawdust and unused wood pieces. Airborne pollutants— particularly wood dust (PM₁₀ and PM₂.₅) from sanding and cutting, along with fumes from paints, solvents, and adhesives—pose significant short- and long-term health risks to workers. This community service project, in collaboration with higher education institutions, aimed to establish long-term control measures. Initial steps involved measuring PM₁₀ and PM₂.₅ concentrations and assessing workers’ blood oxygen levels. Using a descriptive approach, workplace conditions were compared before and after work. Findings revealed a correlation between dust levels and blood oxygen saturation, supporting recommendations for long-term occupational health interventions.

Traffic congestion in Jakarta has become a serious problem, affecting various aspects of life, such as time efficiency, environmental quality, and economic productivity. As one solution to overcome this problem, the Jakarta government is developing a mass public transportation system, including the Light Rail Transit (LRT). The LRT is expected to reduce congestion by providing a more efficient and environmentally friendly transportation alternative. In the process of planning and optimizing the LRT system, discrete mathematics, particularly graph theory, plays a very important role. Graph theory is used to model the LRT station network and track, with vertices representing stations and edges representing connecting lines between stations. With this model, various analyses can be performed to optimize the LRT line, such as finding the shortest path between two stations or evaluating the connectivity between existing stations. The use of graph theory allows the identification of more efficient routes, resulting in faster travel and reduced passenger waiting times. In addition, graph theory also plays a role in optimizing the LRT route by minimizing the number of transfers between stations or avoiding passenger congestion at certain stations. With proper route and network optimization, the LRT can make a significant contribution to reducing traffic congestion in Jakarta. Furthermore, the development of an efficient public transportation system also supports improved air quality and reduces reliance on private vehicles. Overall, the application of graph theory in LRT system planning is a strategic step towards creating more efficient and sustainable transportation in large cities like Jakarta. Beyond route optimization, graph theory is also very useful in analyzing route capacity and passenger distribution along the LRT system.

The “Jak After School” program become an effective medium that strengthens audience loyalty and maintains Jak 101 FM's existence amid digital media industry competition.

Batang Bungo River faces severe pollution from domestic waste and illegal gold mining, which has led to an increase in skin diseases and diarrhea among residents of Tanjung Gedang, exacerbated by poor physical-chemical water quality, including low pH and high levels of Total Suspended Solids (TSS) and Chemical Oxygen Demand (COD), all of which foster the growth of pathogenic microorganisme. This study aimed to identify bacteria and fungi present in Batang Bungo River water, characterizing their colony morphology and microscopic structures to understand the impact of pollution on microbial communities. The methodology involved serial dilution of water samples, followed by inoculation onto Nutrient Agar (NA) media using the pour plate technique, and incubation at 37°C for 24-48 hours. Macroscopic observations of colonies (color, shape, texture) were performed, and representative colonies were stained with crystal violet for microscopic observation at 1000x magnification to identify cellular and hyphal structures. The results indicated the presence of various microorganisms, including Gram-positive bacteria, filamentous fungi, and possibly protozoa, with colonies exhibiting characteristics such as off-white color, rough surfaces, and irregular edges. Microscopic examination after crystal violet staining revealed rod-shaped (bacilli), spherical (cocci) structures, and branched filamentous structures resembling hyphae, consistent with a mixture of bacteria and filamentous fungi. The identification of pathogens like Clostridium, Dermatophilus, and Escherichia coli in previous studies, coupled with the poor water quality, confirms significant microbiological and chemical contamination. Crystal violet proved effective as a stain for microscopic identification of microorganism structures. In conclusion, the water quality of Batang Bungo River is highly concerning and requires serious attention for monitoring and management to safeguard public health and the river ecosystem.
