Liquefied Petroleum Gas (LPG) leakage remains one of the leading causes of fires in both household and industrial environments, highlighting the urgent need for early detection systems that provide fast and accurate warnings. This study aims to design and implement an LPG leakage detection device based on the ESP8266 microcontroller, utilizing the MQ-6 gas sensor and a real-time notification system through Telegram Bot integration. The system operates by reading LPG gas concentration via the MQ-6 sensor, which is then processed by the ESP8266 to automatically activate a buzzer alarm and a DC fan when gas levels exceed the threshold of 200 ppm. Additionally, the system sends instant alert notifications to the user through the Telegram application, allowing remote monitoring of gas conditions. Real-time gas concentration data are also displayed using a 16x2 LCD for direct visualization. System testing was carried out through controlled gas leakage simulations, and the results showed that the device is capable of responding rapidly, with a reaction time of less than 2 seconds after detection, while consistently providing accurate warnings. The integration of Internet of Things (IoT) technology significantly enhances the effectiveness and efficiency of the system, enabling practical and accessible monitoring. Overall, the developed device demonstrates strong potential as an innovative solution to improve safety, minimize fire risks, and raise public awareness regarding the hazards of LPG leakage, making it suitable for practical application in households and small industries.

Dental and oral health is still a significant problem in Indonesia. Riskesdas 2018 data shows that 57.6% of the population has dental and oral problems, while only 2.8% brush their teeth properly. This condition is a serious concern because untreated dental caries can develop into pulp necrosis and subsequently radical gangrene. Both conditions have the potential to cause infections that can interfere with people's quality of life if not treated immediately. This study aims to compare the prevalence of visits to pulp necrosis and radical gangrene based on gender and age at the UPTD Baturiti II Tabanan Health Center during January-March 2025. The research uses a quantitative descriptive method with a purposive sampling technique based on secondary data from the E-Puskesmas system. The results showed that the prevalence of gangrene radicals (7.2%) was higher than that of pulp necrosis (5.9%). Female patient visits were more dominant in both cases, namely 52.7% in pulp necrosis and 56.5% in radical gangrene. The age distribution showed that the age group of 20–44 years dominated in cases of pulp necrosis (42.1%), while gangrene radicals occurred more in the age group of 45–59 years (34.8%). These results indicate a delay in dental care that contributes to the progression of the disease. The high number of these incidents cannot be separated from behavioral factors and the low level of public knowledge in maintaining dental and oral health. Therefore, increasing communication, information, and education efforts at the level of primary health care facilities is essential to encourage public awareness. Early detection and timely treatment are key in preventing serious complications such as pulp necrosis and radical gangrene.

Hypertension, a major risk factor for cardiovascular disease, continues to show increasing prevalence, including in young people. One factor that potentially influences blood pressure is the consumption of monosodium glutamate (MSG), which is often used as a food additive to enhance flavor. Although MSG has long been used in various dishes, recent research suggests that MSG consumption may affect blood pressure through several mechanisms. This study aims to analyze the relationship between MSG consumption patterns and the incidence of hypertension using a narrative review approach. In this study, various scientific journals from 2016 to 2025 that discuss the impact of MSG on blood pressure were analyzed. The analysis results indicate that high and long-term MSG consumption can contribute to increased systolic and diastolic blood pressure. This can occur both directly through increased sodium intake hidden in MSG and indirectly through inflammatory pathways, oxidative stress, metabolic disorders, and changes in the gut microbiota. Several studies have also linked MSG consumption to obesity, which in turn can increase the risk of hypertension. Therefore, uncontrolled MSG consumption may serve as an independent risk factor for hypertension, especially in individuals with cardiovascular susceptibility. In conclusion, it is important to raise public awareness, regulate, and monitor MSG consumption to prevent negative impacts on public health, particularly in clinical practice and public health policy. The increasing prevalence of hypertension, which is increasingly found in young people, is a global health problem that requires serious attention. One factor that is no less important in the development of hypertension is the consumption of food additives, such as monosodium glutamate (MSG).

This study aims to analyze in depth the influence of business legality on the growth and increased competitiveness of Micro, Small, and Medium Enterprises (MSMEs). Business legality is seen as a crucial foundation in strengthening the position of MSMEs in the market, as it not only provides legal certainty but also fosters consumer trust in the quality of the products offered. This study uses a qualitative approach with data collection techniques such as field observations, in-depth interviews with business actors, and relevant documentation studies. The results show an increase in public awareness of the importance of having business legality, as evidenced by the increasing number of MSMEs officially registering their business permits. Furthermore, legality has been proven to increase the credibility of MSMEs, expand market access, facilitate collaboration with the private sector and government agencies, and open up opportunities for obtaining capital support. A significant increase in consumer trust is also evident, as MSME products with legality are more easily accepted and marketed through various distribution channels. Thus, this study confirms that business legality is not merely an administrative requirement, but rather a strategy that can encourage sustainable business growth and increase competitiveness at the local and national levels. In conclusion, the synergy between MSMEs and the government is the main key in encouraging the creation of a healthy, transparent, and highly competitive business ecosystem.

The growing demand for organic fertilizers as an alternative to chemical fertilizers is in line with increasing public awareness of environmentally friendly agriculture. Meanwhile, livestock waste, particularly rabbit urine, remains underutilized and is often discarded, despite its high nitrogen, phosphorus, and potassium content and potential as a raw material for liquid organic fertilizer (LOF). This study aims to design and develop a simple technological innovation for processing rabbit urine into economically valuable LOF, offering new business opportunities for local communities. Another objective is to advance bioactivator-based processing technology to produce an effective, marketable, and eco-friendly organic fertilizer that enhances plant growth. The research employed an applied research method with an experimental approach, including collection and processing of rabbit urine, simple production of LOF, effectiveness testing on horticultural crops with local farmers, and analysis of business feasibility and local marketing strategies. The study resulted in a simple bioactivator-based technology for converting rabbit urine into LOF through a fermentation process of more than 14 days, producing fertilizer rich in nitrogen, phosphorus, and potassium. The LOF improved horticultural crop growth by 25–30% compared to control plants. The group business model provides livestock farmers with new business opportunities, achieving profit margins between 40% and 50%. This research produced a replicable technology guide and usable LOF product, contributing to waste reduction and supporting sustainable agriculture through community-based entrepreneurship.

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.

Environmental issues are complex and increasingly important. This is also true in the industrial sector, particularly in the culinary industry. Currently, public awareness of environmental issues is increasing, leading consumers to consider eco-friendly factors in their daily lives. The concept of eco-friendliness in the coffee shop industry has become an increasingly popular trend. Especially in the food and beverage (F&B) industry, which plays a significant role in waste production, particularly plastic and food waste. Therefore, the concept of eco-friendly practices has emerged in the F&B industry. This can take the form of using environmentally friendly food ingredients, eco-friendly packaging, and the café concept itself, which conveys an eco-friendly image that can increase consumer purchasing interest. This is implemented by Fore Cafe and Coffee Galaxy Bekasi. This study aims to investigate how the eco-friendly concept is implemented and its impact on consumer purchasing interest at Fore Cafe & Coffee Galaxy Bekasi. The study employs a quantitative approach with a sample and population of 99 consumers of Fore Cafe & Coffee Galaxy Bekasi, selected randomly. The analysis uses validity tests, reliability tests, normality tests, and T-statistical test.

The rapid growth of e-commerce in Indonesia has led to significant changes in the way food products are sold, particularly imported foods. While the convenience of online shopping offers great benefits to both consumers and businesses, it has also uncovered several regulatory challenges, especially concerning the labeling of imported food products. A critical issue is the non-compliance with the Indonesian language labeling requirements for these products, which puts consumers at a disadvantage. Such practices not only violate existing consumer protection laws but also pose risks to public health, as consumers may not fully understand the contents or risks associated with foreign food products due to language barriers. This study highlights the need for a more robust framework to enforce labeling laws, focusing on the responsibility of e-commerce platforms. Platforms play a crucial role in bridging the gap between sellers, manufacturers, and consumers. By implementing stricter oversight and monitoring mechanisms, e-commerce platforms could ensure that sellers comply with legal labeling requirements. Furthermore, platforms can act as intermediaries to facilitate consumer complaints and provide dispute resolution services in cases of non-compliance. In addition, the study emphasizes the importance of consumer education. Many consumers are unaware of their rights and the standards they should expect from food products sold online. Thus, there is a need for awareness campaigns and easy access to information on consumer rights, particularly in the context of e-commerce. Strengthening the enforcement of these regulations, providing training for business actors, and improving public awareness will help ensure that imported food products are sold in a transparent, legally compliant manner.

Child marriage remains a serious problem in Indonesia despite the revision of the Marriage Law, which raised the minimum age for marriage to 19 for both men and women through Law No. 16 of 2019. This practice remains widespread, especially in rural areas with a high prevalence due to economic and cultural factors, the existence of marriage dispensation mechanisms, and low legal literacy. The phenomenon of child marriage has multidimensional impacts, including reproductive health risks, high school dropout rates, low quality human resources, economic vulnerability, and psychological problems that can ultimately lead to high divorce rates and intergenerational structural poverty. Through Community Service Activities (PKM), prevention efforts are carried out by providing legal education and outreach regarding the risks of early marriage. Methods used include lectures, presentations, modeling, role plays, and small group discussions involving teenagers, parents, traditional leaders, and religious leaders. The results of the activities showed a significant increase in legal understanding, where 85% of participants were aware of the minimum age for marriage according to the latest regulations. Furthermore, there was increased awareness of the negative impacts of child marriage and a growing commitment from community leaders to continue ongoing outreach. The conclusion of this activity confirmed that marriage law education is an effective strategy in raising public awareness. However, preventing child marriage cannot rely solely on legal outreach; it needs to be strengthened through cross-sector collaboration, integration of materials into the school curriculum, family economic empowerment, and strengthening the role of religious and traditional leaders in shaping social opinion. Therefore, efforts to prevent early marriage require a more holistic, participatory, and sustainable strategy to protect children's rights and realize the development of a quality future generation.

This study examines disaster mitigation efforts in minimizing disaster risk in Manado City and identifies the key challenges as well as the strategies implemented by the Regional Disaster Management Agency (BPBD: Badan Penanggulangan Bencana Daerah). Employing a qualitative descriptive approach, data were collected through interviews, direct observations, and document analysis, with the Head of BPBD serving as the primary informant. The analysis was conducted using Miles et al.’s (2014) interactive model, which consists of data condensation, data display, and conclusion drawing, thereby ensuring systematic interpretation of findings.The results indicate that disaster mitigation efforts in Manado consist of both passive and active strategies. Passive measures include strengthening institutional frameworks, enhancing governance capacity, integrating disaster management planning into regional development programs, and advancing education and research to support long-term disaster risk reduction. In contrast, active mitigation emphasizes community-based actions, such as the installation of disaster warning signs, the provision of basic disaster training for officials and volunteers, the establishment of temporary evacuation shelters, and the implementation of both structural interventions (e.g., drainage construction, flood control) and non-structural measures (e.g., socialization, counseling, and public campaigns). Despite these initiatives, several challenges persist. Limited public awareness, inadequate infrastructure and facilities, a shortage of skilled human resources, weak planning and socialization, complex disaster causes, and environmental vulnerabilities all reduce the overall effectiveness of disaster risk reduction efforts. To address these obstacles, BPBD Manado fosters collaboration with various stakeholders, including government institutions, academia, non-governmental organizations, and local community groups. Moreover, the agency emphasizes the use of disaster risk assessments and hazard mapping as evidence-based foundations for policy formulation and implementation.

Manado City is highly vulnerable to hydrometeorological disasters due to its geographical conditions, rapid and uncontrolled urbanization, and the intensifying impacts of climate change. These risks underline the importance of effective disaster mitigation strategies that go beyond government intervention and involve active participation from communities and non-governmental organizations. In this context, collaboration among various actors becomes a crucial foundation for developing an adaptive and participatory disaster governance system. This study aims to analyze the dynamics of actor collaboration in disaster mitigation efforts in Manado City, with particular emphasis on patterns of interaction, role distribution, and structural as well as cultural barriers that influence the effectiveness of multi-stakeholder synergy. Employing a qualitative case study approach, this research relies on secondary data gathered from official documents, government policy reports, and relevant academic publications. Data were analyzed using thematic analysis to identify key themes and relational dynamics among stakeholders. The findings reveal that although strong driving factors exist—such as a high level of disaster risk, increasing public awareness, and the availability of institutional frameworks—collaboration remains largely procedural and government-dominated, with limited engagement from non-government actors. Challenges such as weak trust among stakeholders, insufficient substantive dialogue, and the absence of an integrated disaster information system continue to hinder the realization of effective collaborative practices. The study concludes by highlighting the urgency of adopting a collaborative governance model that emphasizes equality, mutual trust, and meaningful participation. Theoretically, this research contributes to the discourse on disaster governance by providing insights into actor relations in a disaster-prone urban context. Practically, it proposes an adaptive collaboration framework that can be replicated in other cities facing similar disaster vulnerabilities, thereby strengthening resilience and community preparedness.

This community service program aims to improve the quality of services at Puskesmas (community health centers) through intensive assistance in content creation and digital communication media. The main issue addressed is the low digital literacy among healthcare workers at Puskesmas in managing effective communication media to reach the public. This has led to low community participation in health programs run by Puskesmas. Therefore, this program is designed to enhance healthcare workers' skills in utilizing digital technology for health promotion and improving communication effectiveness with the public. The program implementation involves several stages: (1) an initial survey to assess the condition of existing communication media, (2) training on creating engaging and informative health education content, (3) workshops on graphic design and health promotion video creation, (4) guidance on using social media platforms to disseminate health information, and (5) continuous evaluation and monitoring to ensure the sustainability of the program. This activity involves 25 healthcare workers from 5 selected Puskesmas, with a mentoring duration of 6 months. The results show significant improvements, including: an increase in healthcare workers' ability to create digital content from 30% to 85%, a 200% increase in public engagement with health information, and a 150% increase in the coverage of health promotion services. Additionally, the program has produced 120 pieces of health education content, 15 health promotion videos, and 8 successful digital campaigns that have successfully enhanced public participation in health programs. The long-term impact of this program is the increased public awareness of preventive health and improved access to Puskesmas services. This program can also be replicated in other regions as a model for improving the quality of primary healthcare services through optimal use of digital technology, which can accelerate the achievement of national health development goals.

The development of information and communication technology (ICT), particularly the use of Artificial Intelligence (AI), the Internet of Things (IoT), and big data, has transformed Indonesia's national security threat landscape. Threats that previously focused on traditional military aspects have now shifted to non-traditional cyber threats, such as cyberattacks, digital espionage, and infrastructure sabotage. According to PROXSIS IT GRC data, in 2024, more than 19 million cyberattacks were recorded against websites in Indonesia. While this figure is a decrease compared to the previous year, this trend is thought to reflect a shift towards more structured and organized tactics by threat actors. In response, the Indonesian government established the National Cybersecurity Action Plan 2024–2028 as a strategic guideline. Furthermore, cyber diplomacy is being promoted through bilateral and multilateral cooperation, for example through the signing of memorandums of understanding (MoUs) with the UK and Kaspersky. This cooperation includes the exchange of intelligence information, strengthening human resource capacity, raising public awareness regarding cybersecurity, and protecting critical information infrastructure. This study uses non-traditional security theory and defense diplomacy to analyze the strategies, challenges, and prospects of Indonesia's cyber policy. The analysis demonstrates that cyber defense diplomacy plays a crucial role as an instrument for integrating technology, regulation, and international collaboration in safeguarding digital sovereignty. In addition to strengthening threat detection and mitigation capabilities, this diplomacy also builds networks of trust with partner nations, which is essential amidst the increasing complexity of global threats. Therefore, in the era of digital globalization, full of interconnections, cyber defense diplomacy serves not only as a national protection tool but also as Indonesia's contribution to global cybersecurity stability. This effort prioritizes synergy between technological innovation, law enforcement, and sustainable international cooperation.

Waste management remains a serious problem, particularly in rural areas, which generally have relatively low levels of environmental awareness. Inorganic waste such as plastic, glass, and aluminum is a major concern because it takes hundreds of years to decompose naturally. This situation poses potential long-term environmental hazards, including soil and water pollution, and ecosystem disruption. Therefore, effective educational efforts are needed to raise public awareness of waste issues. This community service activity was carried out in Sarah Perlak Village, Sungai Mas District, West Aceh Regency. The focus of the activity was the installation of educational signs containing information about the decomposition time of various types of waste. Implementation methods included direct observation to identify specific problems at the site, informal outreach to local residents, demonstrations related to waste sorting, and the creation and installation of educational signs. The signs were made from wooden planks and decorated with real waste such as plastic bottles, aluminum cans, and used paper, thus providing a tangible visualization to the community. The results of the activity showed that the visual approach through educational signs was able to attract the attention of residents, both children and adults. The information was presented clearly and accompanied by real-life examples, making the message easier to understand and remember. In addition, direct interaction through outreach and demonstrations provided an opportunity for residents to ask questions and share experiences related to waste management. Overall, this educational medium has proven effective in conveying environmental messages, raising awareness, and motivating the community to start sorting and reducing waste at the source. Going forward, this program is planned to be expanded through training in processing waste into useful products, thereby not only reducing pollution but also providing economic benefits to 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.
