The implementation of smoking prohibition policies in Islamic boarding schools continues to depend largely on manual monitoring methods, which often face challenges related to consistency and supervision range. This study aims to design an Internet of Things (IoT)-based cigarette smoke detection system as an alternative monitoring approach that is more effective, measurable, and sustainable. The system design combines an MQ-2 gas sensor with a NodeMCU ESP8266 microcontroller programmed through the Arduino IDE platform. When smoke levels detected by the sensor exceed the predetermined limit, the system automatically triggers a buzzer and LED as warning indicators while simultaneously sending monitoring data to cloud-based platforms such as Firebase or ThingSpeak for real-time observation through web interfaces. The research outputs include a comprehensive system design consisting of system architecture, electronic circuit schematics, flowcharts, and pseudocode that are systematically arranged to support future prototype development and implementation. Through this design, the proposed system is expected to provide an initial technological solution that can enhance the effectiveness of monitoring and enforcing smoke-free regulations within Islamic boarding school environments.

The results of the study show that pricing strategy contributes dominantly to increasing sales, but the lack of digital promotion causes limited market reach. Micro, Small, and Medium Enterprises (MSMEs) play a crucial role in driving national economic development and providing employment. However, in facing an increasingly competitive market, MSMEs need to implement efficient marketing strategies to ensure sustainability and sustainable growth. This community service activity aims to provide knowledge and assistance to Indonesian Es Teh MSMEs regarding the implementation of flexible marketing strategies, both through digital and traditional channels. The activity took place at the Es Teh Kampung Solo outlet in Kramatwatu Square. The methods used included counseling, training, and assessment of marketing strategy implementation, with a primary focus on optimizing social media as an interactive and competitive digital promotional tool. The results of this activity demonstrated a significant increase in MSMEs' understanding of strategic marketing planning, promotional innovation, and the use of digital platforms to expand market reach. Thus, it is hoped that digital-based marketing strategies can strengthen the competitiveness and sustainability of MSMEs. This activity is expected to contribute to increasing the competitiveness and sales volume of the Kampung Solo Es Teh MSME in a sustainable manner through the implementation of a modern marketing approach that is responsive to technological changes.

This study aims to analyze the understanding of Micro, Small, and Medium Enterprises (MSMEs) in Harjosari II Village regarding Islamic financial inclusion and its contribution to expanding access to business capital financing. Although the national financial inclusion index continues to increase, the implementation of Islamic financial inclusion still faces challenges at the grassroots level. This research used a descriptive qualitative method with data collection techniques consisting of observation, documentation, and in-depth interviews with MSME owners in Harjosari II Village and staff from KSPPS & BMT Syariah Sejahtera (SS) Medan. The findings show that MSME owners’ understanding of Islamic financial inclusion is influenced by religiosity and the perception of justice through the profit-sharing system. Islamic financial inclusion is implemented through a kinship approach and simplified administrative procedures for the informal sector. However, the main obstacles to expanding financing access include limited Islamic financial literacy, restricted financing ceilings, and entrepreneurs’ lack of confidence in formal banking procedures. Islamic financing contributes to increasing production capacity and providing spiritual peace of mind by offering capital alternatives free from usury (riba). This study recommends strengthening direct technical socialization and implementing more flexible financing ceiling policies to support MSME growth in suburban areas.

Uterine myoma is a benign smooth muscle tumor of the uterus commonly found in women of reproductive age and may cause symptoms related to mass effect and hematologic disturbances. We report the case of a 41-year-old woman presenting with progressive vaginal pain for 3 months, accompanied by low back pain and impaired daily activities, without vaginal bleeding, vaginal discharge, fever, or urinary or defecatory symptoms. Laboratory examination revealed severe microcytic hypochromic anemia with a hemoglobin level of 4.7 g/dL, while ultrasonography demonstrated a 9.93 × 10.32 cm mass described as symmetric, well circumscribed, and hyperechoic, leading to a working diagnosis of uterine myoma with anemia. The patient was managed with general condition monitoring, intravenous fluids, analgesics, transfusion of four units of packed red cells, and laparotomy as definitive intervention. Following transfusion and surgery, the hemoglobin level increased to 9.4 g/dL and subsequently to 11.0 g/dL, accompanied by improvement in postoperative symptoms and clinical condition. This case demonstrates that a large uterine myoma may present predominantly with pelvic pain and functional impairment in the absence of vaginal bleeding. A comprehensive approach involving systematic evaluation, preoperative correction of anemia, appropriate surgical intervention, and postoperative monitoring is essential to improve safety and clinical outcomes in patients with symptomatic pelvic masses.

Clean and Healthy Living Behavior (PHBS) is a promotive and preventive effort that aims to improve the degree of public health through behavior change. Nursery reservoir employees have a high risk of exposure to the work environment in the form of dirty water, biological waste, and pathogenic microorganisms. This community service activity was carried out to increase the knowledge and practice of PHBS among employees of the nursery reservoir in Juata Tarakan based on national PHBS indicators. The implementation method includes counseling, demonstration, and evaluation using pre-test and post-test. The results showed a significant increase in employee knowledge, with an average pre-test score of 58.7 increasing to 78.3 in the post-test. The statistical test resulted in a value of p = 0.000 (p < 0.05), which confirms the effectiveness of PHBS educational interventions in improving workers' health knowledge and behavior. These findings provide practical implications that counseling-based education and demonstrations can be an effective strategy in encouraging the implementation of PHBS in risky work environments. Thus, this activity is expected to be able to support the creation of a healthier work environment, increase productivity, and become a model for community-based occupational health interventions.

Dengue Hemorrhagic Fever (DHF) remains a significant public health problem in tropical countries, including Indonesia. The presence of Aedes aegypti larvae is an important indicator of dengue transmission risk and is influenced by environmental factors, particularly temperature and humidity. This study aimed to analyze the relationship between temperature and humidity and the presence of mosquito larvae in Meteseh Village, Tembalang District, Semarang City. This analytical observational study employed a cross-sectional design involving 100 households selected through quota sampling. Data were collected through direct observation and measurement of temperature and humidity using a thermo-hygrometer, then analyzed using the Chi-square test. The results showed a significant association between temperature and the presence of mosquito larvae (p=0.000), while humidity was not significantly associated with larvae presence (p>0.05). Temperature was identified as a more influential environmental factor in supporting mosquito larvae existence than humidity in the study area. These findings highlight the importance of environmental-based vector control strategies, particularly through management of microhabitat temperature conditions, to support dengue prevention.

Tinea favosa is a rare but destructive form of chronic dermatophytosis fungal infection. It is marked by the development of scutules (yellowish, cup-like crusts) and can lead to permanent cicatricial alopecia if not treated appropriately. Although its prevalence is decreasing globally, sporadic cases are still common in areas with poor sanitation. Trichophyton schoenleinii is the primary medical cause of Tinea favosa, but it can also be caused by Trichophyton violaceum or Microsporum gypseum. This report discusses a case involving a 7-year-old boy who exhibited classic clinical signs of favus. Diagnostic procedures included a physical examination, direct microscopic examination with 10-20% KOH solution, and culture on Sabouraud Dextrose Agar (SDA) to identify the fungal species. Microscopic examination revealed branching and fragmented hyphae (arthrospores) and air tunnels within the hair shaft. Culture confirmed Trichophyton schoenleinii as the primary etiologic agent. The patient was treated with oral griseofulvin combined with ketoconazole cream for 8–12 weeks. Follow-up showed resolution of the crusts and cessation of the inflammatory process, although areas of fibrosis showed permanent hair loss.

The transformation of payment systems from cash to digital through the Quick Response Code Indonesian Standard (QRIS) is part of financial transaction modernization in Indonesia. This transformation has begun among Micro, Small, and Medium Enterprises (MSMEs) in the Baduy community, particularly in Baduy Luar, which has higher interaction with external communities. However, the adoption of digital payment systems has not been fully supported by adequate financial management capabilities. This community service activity aims to identify the transformation process of payment systems and describe the financial literacy conditions of Baduy MSMEs. The method used is a descriptive qualitative approach through in-depth interviews and field observations. The results show that some MSMEs have adopted QRIS through Bank BRI as an alternative payment method alongside cash and have utilized social media such as TikTok Live and Instagram for product marketing. The main sources of income include handicrafts, traditional clothing, accessories, and food products. However, financial management practices remain simple and lack systematic recording. This indicates improved financial inclusion but not yet accompanied by adequate financial behavior. Therefore, strengthening financial literacy is essential to support sustainable financial modernization in the Baduy community.

Inventory management is a crucial aspect of business sustainability, particularly for Micro, Small, and Medium Enterprises (MSMEs) that often face limitations in data management and technological adoption. Selaras Muba Lestari is Incubation Center, which supports MSMEs in Musi Banyuasin Regency, encounters challenges in managing product inventory due to reliance on manual recording systems. This study aims to design and develop a web-based inventory application using the Laravel framework to improve the efficiency and accuracy of stock management. The research adopts the Software Development Life Cycle (SDLC) Waterfall model, which includes requirements analysis, system design, implementation, and testing. The results indicate that the developed system is capable of improving data accuracy, accelerating the recording process, and providing real-time inventory reports. Furthermore, this study reinforces previous findings that digitalizing inventory systems serves as a strategic solution to enhance the competitiveness of MSMEs.

This study aims to evaluate simple bookkeeping practices in traditional Micro, Small, and Medium Enterprises (MSMEs) through a comparative study between Nasi Padang and Warung Madura MSMEs. The background of this study is based on the still low level of financial literacy of MSMEs, especially in terms of recording and managing business finances, which are often not done systematically. The methods used in this activity include direct observation, simple bookkeeping training, and evaluation of the implementation of financial recording. The results of the observation indicate that Nasi Padang MSMEs have not kept complete financial records and still mix personal finances with business finances. Meanwhile, Warung Madura MSMEs have kept simple bookkeeping and separated business finances from personal finances, but the records are not organized neatly and systematically. The implementation of simple bookkeeping training has a positive impact on improving business actors' understanding in recording cash inflows and outflows and preparing simple profit and loss reports. The evaluation results show an increase in the ability of MSMEs to manage business finances in a more structured manner. Thus, simple bookkeeping plays an important role in increasing financial transparency, assisting business decision-making, and supporting the sustainability of MSMEs. This study recommends ongoing mentoring so that simple bookkeeping practices can be consistently implemented by MSMEs.

Clean water availability is an essential component of hospital hygiene and sanitation operations, including hand hygiene, environmental cleaning, linen management, food sanitation, and infection prevention. RSUD Sumbersari Bantul Metro Selatan still relies on one bore well and has limited water storage without a permanent backup source. This study aimed to analyze the adequacy of clean water quantity and quality in supporting hygiene and sanitation operations at RSUD Sumbersari Bantul Metro Selatan in 2026. This study used a descriptive analytic design. Data were collected through observation, interviews, water discharge and consumption measurement, document review, and laboratory examination of clean water samples. The analysis compared water availability, water demand, unit-based distribution needs, and water quality with the standards of Ministry of Health Regulation Number 2 of 2023. The results showed that during January-March 2026, the hospital served 154 inpatients and 1,028 outpatients and had 151 staff members. The total clean water requirement was 715.44 m3/90 days, while the available water was only 414.00 m3/90 days, fulfilling 57.87% of the required amount. The average daily need was 7.95 m3/day, compared with the availability of 4.60 m3/day. High-risk service units, particularly inpatient care, emergency services, intensive care, CSSD, isolation, maternity care, laundry, and nutrition services, require priority water distribution. Laboratory testing found Escherichia coli and total coliform at 19 CFU/100 ml each, exceeding the required standard of 0 CFU/100 ml. In conclusion, the quantity and microbiological quality of clean water at RSUD Sumbersari Bantul have not adequately supported optimal hygiene and sanitation operations.

This study aims to develop a Strategic Learning Enabler model by reconfiguring the role of Information and Communication Technology (ICT) units to enhance Generation Z student productivity in digital higher education. The research is motivated by the gap between digital transformation demands and the predominantly technical-operational role of ICT units. Using a quantitative explanatory design, this study examines the causal relationships among ICT role reconfiguration, adaptive learning systems, and student productivity. Data were collected through questionnaires distributed to Generation Z students engaged in digital learning environments and analyzed using Structural Equation Modeling (SEM). The findings indicate that Generation Z students exhibit high responsiveness to structured tasks but lack continuity in learning activities due to weak self-regulated learning. The study also reveals that adaptive learning systems significantly mediate the relationship between ICT transformation and student productivity. The proposed model emphasizes digital governance, learning analytics, and micro-tasking structures as key components in building sustainable academic productivity. This research contributes both theoretically and practically by offering an institutional framework for digital learning transformation in higher education.

Digital transformation has intensified scholarly interest in leadership; however, existing research predominantly emphasises leadership styles and strategic orientations, leaving the role of micro-level leadership behaviours underexplored. This qualitative systematic literature review synthesises prior studies to examine how everyday leadership behaviours function as behavioural antecedents of organisational performance in digital transformation contexts. Drawing on a structured review of interdisciplinary literature, the study identifies cognitive, relational, and adaptive leadership behaviours as central mechanisms through which digital initiatives are translated into performance outcomes. The findings reveal that micro-level behaviours—such as sensemaking, empowering communication, psychological safety cultivation, and behavioural flexibility—indirectly shape organisational performance by fostering digital capabilities, innovative work behaviour, and employee resilience. By shifting the analytical focus from abstract leadership constructs to observable behavioural micro-foundations, this review contributes to digital leadership and organisational performance literature and offers integrative insights for future empirical research and managerial practice

The rapid evolution of digital technologies has fundamentally reshaped tax administration systems, particularly for Micro, Small, and Medium Enterprises (MSMEs), which constitute a critical driver of economic development yet continue to demonstrate suboptimal levels of tax compliance. This study aims to critically examine the role of Application Programming Interface (API)-based tax automation in enhancing MSME tax compliance through a systematic narrative literature review approach. Employing a qualitative design, this study synthesizes recent scholarly works published within the last five years to identify patterns, relationships, and emerging trends in digital taxation practices. The findings indicate that API-based automation significantly improves administrative efficiency, minimizes human error, and facilitates real-time data integration between taxpayer systems and tax authorities. Moreover, such integration enhances transparency and reduces compliance costs, thereby fostering voluntary compliance behavior among MSMEs. Nevertheless, the effectiveness of this technological intervention is contingent upon several structural and behavioral factors, including digital literacy, technological readiness, and the availability of reliable digital infrastructure. Persistent disparities in these areas may constrain the scalability and inclusiveness of API implementation. This study underscores that API-based tax automation represents a transformative policy instrument in modernizing tax administration systems, provided it is supported by coherent regulatory frameworks, capacity-building initiatives, and equitable infrastructure development. The findings contribute to the broader discourse on digital taxation by offering a conceptual foundation for developing adaptive and sustainable compliance strategies in the era of economic digitalization

This study aims to examine the gastronomy of the traditional culinary dish Ayam Napinadar as part of Batak cultural identity, covering aspects of history, ingredients, processing techniques, cultural values, and preservation challenges. The background of this research is based on the importance of maintaining the sustainability of traditional cuisine amid modernization and changes in consumption patterns. The method used is a qualitative approach through in-depth interviews with three informants, namely an MSME (Micro, Small, and Medium Eterprises) practitioner, a traditional leader, and a consumer. The results show that Ayam Napinadar has a unique characteristic in the use of andaliman and blood (gota) as its distinctive flavor. Traditionally, the cooking process involves grilling over firewood to produce a characteristic smoky aroma, although it has now shifted to more practical methods without altering the original recipe. From a cultural perspective, Ayam Napinadar holds symbolic meaning as an expression of prayers, blessings, and joy in various Batak traditional ceremonies. However, there are challenges in its preservation, such as the declining participation of younger generations in traditional activities and the increasing influence of modern foods. In conclusion, Ayam Napinadar functions not only as food but also as a medium for preserving cultural values and ethnic identity. This study provides benefits as a basis for developing gastronomic tourism and strategies for preserving traditional cuisine through education, collaboration, and the use of modern promotional media.

Micro, Small, and Medium Enterprises (MSMEs) in Kemasantani Village have considerable potential in developing cassava-based products using MOCAF flour, particularly Antari chips. However, limited brand identity, unattractive packaging, and the underutilization of digital marketing have constrained product competitiveness and revenue growth. This community service program aimed to strengthen branding and optimize digital marketing strategies to support MSME revenue growth. A qualitative participatory approach was employed through surveys, interviews, observations, documentation, and direct assistance in brand identity development, packaging redesign, and social media management. The results indicate improvements in product image, packaging attractiveness, and market reach through digital platforms. The integrated application of branding and digital marketing successfully increased consumer engagement and led to an approximate 35% increase in MSME revenue within a three-month period. These findings suggest that strategic branding and digital marketing are effective approaches for enhancing competitiveness and ensuring the sustainability of locally based MSMEs in rural areas.

The high dependence of national food on imported commodities, especially wheat, creates vulnerabilities in the aspect of National Food Security. This study examines the position and role of Modified Cassava Flour (Mocaf) Micro, Small, and Medium Enterprises (MSMEs) in Padi Village as a pillar of local food diversification and its implications from the perspective of Constitutional Law (HTN) on the internal sector (community, MSMEs, and Village Government). Mocaf, as a gluten-free cassava derivative product, has the potential to be a substitute for wheat flour. The research method used is Empirical Normative Law with a conceptual and legislative approach, reinforced by primary data regarding the operational model of MSMEs in Padi Village. The results of the study indicate that Mocaf MSMEs at the village level act as strategic legal subjects in realizing Article 33 paragraph (3) of the 1945 Constitution (UUD 1945) and Law Number 18 of 2012 concerning Food. The implications of HTN are seen in the need for regulatory harmonization and strengthening village autonomy through budget policies and assistance that ensure the sustainability of production and marketing. The position of MSMEs demands stronger recognition of the internal role of villages in the national food governance structure.

Facies analysis and thin-section petrography are complementary and essential approaches for determining the lithological characteristics of deep-water deposits. Deep-water sediments are formed by diverse depositional processes such as turbidity currents, debris flows, slumps, and pelagic suspension settling, producing a wide range of lithofacies with distinctive textural, compositional, and sedimentary structural attributes. This literature review synthesizes studies that apply facies analysis and thin-section petrography to characterize deep-water deposits across various basins and geological ages worldwide. Field-based facies analysis emphasizes lithology, sedimentary structures, bed geometry, and vertical–lateral facies relationships to reconstruct depositional environments. In contrast, thin-section petrography provides microscopic insights into mineral composition, grain texture, cement types, porosity, and diagenetic features that are not observable in the field. The integration of these methods, often combined with advanced techniques such as XRD, SEM, and geochemical analyses, has proven effective in distinguishing lithofacies, understanding sedimentary processes, and evaluating reservoir quality. The review highlights that grain size, sorting, cement type, pore-throat size, and diagenetic processes are key controls on lithological characteristics and reservoir potential in deep-water systems. Therefore, the combined application of facies analysis and thin-section petrography provides a comprehensive framework for interpreting deep-water sedimentary systems.
