This research aims to analyze the effect of taste and service quality on customer satisfaction at Hilande Koffie Medan. As the café business continues to grow in urban areas, customer satisfaction becomes a key factor in business sustainability. Hilande Koffie, located in Medan, offers a variety of pastries and beverages that attract many customers, yet some inconsistencies in taste and service have raised concerns. This study uses a quantitative method with a sample of 45 respondents, applying multiple linear regression analysis through SPSS version 25. The results show that both taste and service quality have a positive and significant effect on customer satisfaction, either partially or simultaneously. The coefficient of determination (Adjusted R²) shows that 65% of the variation in customer satisfaction can be explained by the two independent variables. The findings suggest that maintaining consistency in taste and improving staff professionalism are crucial in enhancing overall customer experience. Therefore, Hilande Koffie is recommended to continuously evaluate and improve both aspects to increase customer satisfaction and loyalty.  

This study examines the cultural diversity of the Batak people in North Sumatra through a systematic literature review of three core pillars: language, traditions, and social systems. Findings reveal significant inter-sub-ethnic variations (e.g., Toba, Karo, Simalungun), including linguistic diversity (V-S-O structures in Toba vs. complex affixation in Karo), distinct rituals (such as Saur Matua and Manulangi Natuatua), and kinship systems rooted in the Dalihan Na Tolu philosophy. Amid positive dynamics like digitalization of traditional arts (Tortor Martonun) and gender transformations, Batak culture faces critical threats: symbolic desacralization (commodification of ulos textiles), kinship disintegration (atomization of Dalihan Na Tolu due to urbanization), and erosion of transcendental knowledge (extinction of Hata Andung rituals). The study recommends a community-based participatory research (CBPR) preservation model, integrating local content curricula and geographical indication certification. A key limitation is the literature bias toward the Toba sub-group, necessitating urgent comparative studies across sub-ethnicities and analysis of digital media’s impact on cultural transmission.

Situated on 3.6 hectares in Kebayoran Baru, South Jakarta, Langsat Park operates as a vital urban lung, sequestering carbon, stabilizing the microclimate, attenuating noise pollution, and enhancing rainwater infiltration. This study aims to develop strategies to optimize the park’s ecological functions through a descriptive qualitative case study approach, encompassing direct observation, semi-structured interviews with park managers and community members, and document analysis using triangulation techniques. The findings reveal a diverse vegetation structure that supports air quality improvement and wildlife habitat, yet persistent challenges such as facility damage, vandalism, and waste accumulation disrupt the ecosystem. Proposed strategies include ecological and recreational zoning, implementation of nature-based solutions, increased community engagement via educational and conservation programs, and the reinforcement of regulations and routine maintenance. The implementation of these strategies is expected to strengthen stakeholder collaboration, sustain the park’s ecological functions as an essential urban green space, and serve as a benchmark for urban park management in the context of rapid urbanization.

This analysis is expected to encourage society to be more critical in understanding the impact of modern lifestyles on personal and social well-being.

Domestic helpers (DWs) play a vital role in sustaining household life in urban areas, yet their legal position in the Indonesian labour system remains marginal and vulnerable, without adequate legal protection. This research aims to analyse juridically normatively the legal position of domestic workers within the framework of national labour law and identify regulatory gaps and structural barriers that hinder the protection of their basic rights. Using a literature study method and a normative juridical approach, this research examines legislation, legal doctrine, and recent scientific literature. The analysis shows that Law No. 13 Year 2003 does not recognise domestic workers as formal workers, and Permenaker No. 2 Year 2015 is non-binding, creating a legal vacuum that results in vulnerability to exploitation, discrimination, and human rights violations. The absence of special regulations such as the PPRT Bill and the non-ratification of ILO Convention No. 189 exacerbate structural injustice against domestic workers. This research concludes that the legal protection of domestic workers is very weak normatively and practically, so regulative reform is needed through the enactment of special laws and harmonisation of national laws with international human rights standards in order to create a fair, inclusive and social justice-based employment system.

This study aims to analyze the role of the Surabaya Smart City Program in supporting environmental governance in Kampung Sehati, Surabaya City. The Smart City initiative implemented by the Surabaya City Government is part of an urban governance innovation based on integrated information technology and community participation. Kampung Sehati, as one of the pilot areas, serves as a case study to examine how technological approaches, regulations, and citizen engagement shape participatory, adaptive, and sustainable environmental governance. This research uses a qualitative descriptive method through in-depth interviews, field observations, and document studies. The results show that the Surabaya Smart City Program facilitates environmental management through digital platforms such as e-lingkungan, citizen reporting applications, and active community involvement in data-based decision-making. However, challenges remain regarding citizens' digital literacy, unequal participation, and the sustainability of programs after intervention ends. It can be concluded that this program significantly contributes to environmental governance in Kampung Sehati, especially in fostering collaboration between the government, community, and technology, although further efforts are needed to overcome the existing obstacles.

This study aims to analyze the level of community participation in the “Roti 7 Lapis” program (Response Time 7 Minutes of Free Fire Service) initiated by the Surabaya Fire and Rescue Department. Using a descriptive qualitative approach and Arnstein’s ladder of participation theory, the research explores citizen involvement in reporting, prevention, and early fire response. Data were collected through interviews and observations in two densely populated areas: Sidotopo Jaya and Kedung Rukem. The findings indicate that community participation has reached the "citizen control" level within the partnership stage, although it is not evenly distributed across regions. The main challenges include low public awareness, hoax reports to the 112 call center, and limited access for fire trucks due to environmental conditions. This study demonstrates that the success of the program relies not only on rapid response but also on efforts to foster meaningful community engagement. These findings contribute to the literature on participatory public policy within the context of urban emergency services.

Waste management in urban areas such as South Jakarta remains a major challenge, particularly at the household level. This study aims to examine the role of Bank Sampah Mekar Sari in implementing circular economy principles through community-based waste management. The research employed a descriptive qualitative approach, with data collected through in-depth interviews, observation, and documentation. The findings show that Bank Sampah Mekar Sari functions not only as a collection point for inorganic waste but also as a center for educating and empowering residents to sort and manage waste sustainably. The practices observed, such as household-level sorting, partnerships with recycling partners, and material reuse, reflect the core principles of the circular economy. In addition, collaboration among community members, local government, and the private sector contributes to the development of a participatory waste management ecosystem. This study recommends replicating similar models in other regions and highlights the importance of regulatory and institutional support in strengthening local waste management systems.

Urban street art has become a significant visual medium reflecting identity, resistance, and cultural memory within Southeast Asian cities. This study explores how street art in urban environments such as Jakarta, Bangkok, and Manila serves as a visual narrative, embedding local symbolism and identity expression into public space. The objective is to analyze how visual elements in street art communicate social, cultural, and political messages. A qualitative method is employed, utilizing visual semiotics and ethnographic observation to examine selected murals and graffiti. The findings reveal that recurring motifs, such as traditional symbols, mythological figures, and vernacular language, function as tools of cultural assertion and urban storytelling. These visual narratives not only document community histories but also challenge dominant urban narratives, reclaiming marginalized voices. The study highlights the role of street artists as agents of social commentary and urban transformation. Implications suggest that recognizing street art as a form of visual narrative contributes to a broader understanding of cultural identity construction in urban Southeast Asia.

This study aims to compare the level of carbon monoxide (CO) air quality in Green Open Space (GOS) and Non-Green Open Space (NGOS) along the Abepura–Sentani main road in Jayapura City. The research was conducted in two locations: the Taman Makam Pahlawan Denzipur Waena (GOS) and the front area of Mega Waena (NGOS). CO levels were measured using a CO smart sensor over a period of one week, with measurements taken in the morning, noon, and afternoon at six sampling points. The findings indicate that CO concentrations are significantly lower in GOS areas compared to NGOS areas. The presence of vegetation in GOS helps reduce CO pollution by acting as a natural filter. These results highlight the importance of maintaining and developing green open spaces in urban areas as part of efforts to reduce air pollution and improve public health.

Crypto asset transactions in Indonesia have rapidly developed alongside financial technology advancements, yet they pose legal challenges concerning investor protection. Under Indonesian civil law, civil liability for investor losses may be based on Article 1243 and Article 1365 of the Civil Code, depending on whether the loss arises from a breach of contract or an unlawful act. Additionally, the Consumer Protection Act may serve as a legal basis in cases involving violations of consumer rights. However, the application of such liability encounters juridical obstacles, including the absence of specific regulations defining the legal status of crypto assets as legal objects, regulatory gaps regarding business actors’ obligations, and evidentiary difficulties due to the anonymous nature of digital transactions. In this context, regulatory reform is essential to establish legal certainty and effective investor protection. The regulation should include digital security standards, transparent risk disclosures, and dispute resolution mechanisms. Active roles of Bappebti and the Financial Services Authority (OJK) in oversight, as well as legal literacy for the public, are critical to creating a responsible and secure crypto asset trading ecosystem.

The increasing number of elderly people in Yogyakarta City demands the provision of an inclusive environment that supports the welfare of the elderly. This study aims to assess the suitability of Yogyakarta City for the concept of an elderly-friendly city based on seven main variables: green open space, public transportation, pedestrian facilities, health services, social support, elderly-friendly intergenerational interactions, and advocacy for the basic rights of the elderly. The research used a quantitative approach with observation and questionnaire methods to elderly people in all sub-districts in Yogyakarta City. The data were analyzed using a Guttman scale to determine the level of suitability of each variable. The results showed that overall Yogyakarta City is classified as “suitable” for the concept of an elderly-friendly city, with a total score of 5.32 out of a maximum scale of 6.80. Four variables meet the suitability criteria, namely public transportation, health services, social support, and intergenerational interaction. Meanwhile, the other three variables are still not fully suitable and require improvement. This study recommends improvements in these three aspects so that the implementation of the concept of an elderly-friendly city in Yogyakarta City can be more optimal and sustainable.

Emergency complaint services are a critical component of public service delivery, requiring speed, coordination, and integration across multiple agencies.
