Abstract:Level design is one of the key components in determining the gameplay experience in 2D platformer games. However, manual level design is time-consuming and difficult to scale. Graph theory can be used to represent the abstract…
stract structure of a level, with nodes as spatial units and edges as paths connecting those spaces. The problem is that this graph structure cannot always be directly translated into a valid and playable physical layout due to platformer constraints, such as jump height, safe distance, and gravity. This research proposes a chunk-based transformation approach, in which each graph node is represented as a fixed-size level chunk containing a platform layout, obstacles, and entry and exit points. The transformation of the graph into a physical level is carried out through the selection, arrangement, and alignment of chunks based on the graph’s topology. This study aims to design a framework for transforming an abstract graph G=(V,E) into a chunk-based 2D platformer level layout. The method used is qualitative-descriptive, involving the formulation of a graph model, rules for mapping and arranging chunks, and playability criteria. The results of the study reveal three main stages: mapping vertices to corresponding chunks, arranging chunks according to the graph’s structure, and validating reachability using an automatic path-finding agent.
Abstract:Visual perceptual ability is one of the important aspects of cognitive development in early childhood. This ability is related to children’s capacity to recognize, differentiate, interpret, and understand information received…
eceived through vision. It includes the recognition of shapes, colors, sizes, patterns, and visual relationships, which are essential for children’s learning readiness. This study aims to improve the visual perceptual abilities of children aged 5–6 years at TK Sarantau Sasurambi through smartboard-based learning. The research employed a Classroom Action Research (CAR) method conducted in several cycles, namely planning, action, observation, and reflection. The research subjects were children aged 5–6 years. The research instruments included observation sheets of visual perceptual abilities (visual discrimination, visual memory, matching, sequencing, spatial relations, and eye–hand coordination), observation sheets on the use of the smartboard, and field notes. The results showed an improvement in visual perceptual abilities from the pre-cycle to Cycle I and Cycle II. Children’s mastery in the pre-cycle reached only 45%, increased to 65% in Cycle I, and reached 88% in Cycle II. The use of smartboards proved effective as it offers interactive and engaging visual learning experiences and facilitates children’s direct manipulation of objects. Therefore, smartboard-based learning is highly effective in improving the visual perceptual abilities of children aged 5–6 years.
Abstract:This study explores how influencer marketing shapes digital identity and spatial relations in Makassar, Indonesia, through a spatially grounded urban ethnography approach. This framework enables a deep reading of how urban…
an residents engage with digital practices to navigate symbolic and spatial exclusion generated by influencer content. Through social media observation, narrative interviews, and the tracing of urban locations featured in visual representation, the study finds that influencer marketing does not merely sell products—it also reproduces social hierarchies through aesthetic spatiality and the logic of visibility.
Yet, amid such exclusions, marginalized communities deploy diverse tactics of resistance, including visual reengineering, the use of alternative locations, and digital irony that disrupt dominant narratives. These findings suggest that digital identity is not passively consumed but actively negotiated through concrete and often unexpected spatial relations. Drawing on Lefebvre’s theory of the production of space, Urry’s concept of digital mobilities, and Gandy’s politics of infrastructure, the study shows how cities and digital spaces co-constitute a contested symbolic terrain.
The article’s main contribution lies in advancing a Global South perspective, where digital technologies and aesthetics are practiced contextually and do not always conform to the logics of global capitalism. This research underscores that urban—and digital—space is not solely produced from above, but also from below, through the everyday agency of ordinary citizens.
Abstract:Makassar is currently facing a mobility crisis that is not merely technical, but deeply embedded in the social, political, and spatial dimensions of urban life. Mobility spaces in the city—roads, transport nodes, and travel…
ravel rhythms—have become contested arenas where technocratic planning collides with residents’ everyday realities. This study aims to examine how mobility spaces in Makassar are produced, negotiated, and lived by urban dwellers amid infrastructural dysfunction and unequal access.
Using a qualitative, city-based ethnographic approach, the research was conducted across key mobility corridors and densely populated neighborhoods. Conceptually, this study draws on the frameworks of spatial anarchy (Castells & Smith), temporal disorientation (Zerubavel), and the politics of infrastructure (Larkin) to analyze how disorganized space and time shape citizens’ mobility experiences.
Findings reveal that Makassar’s mobility space is marked by spatial fragmentation, erratic urban rhythms, and various forms of micro-resistance—such as the use of informal routes, modifications to pete-pete (minibus) trajectories, and the occupation of street space by informal economic activities.
This research contributes theoretically to urban anthropology and the discourse on mobility justice by foregrounding the need to understand cities from below—through the lived experiences of residents who continuously adapt within unruly and unstable urban environments
Abstract:This study explores how marginalized communities in Makassar construct and sustain their life rhythms amidst the temporal pressures shaped by infrastructure systems, mobility regimes, and urban development logics. Employing…
ing a space- and time-based urban ethnographic approach, the research traces residents’ daily tactics, rhythmic narratives, and spatial practices in navigating mobility exclusion and the accelerating, non-inclusive urban pace.
Field findings reveal that residents engage in various forms of micro-resistance—such as adjusting selling hours, utilizing interstitial moments in urban space, and cultivating social rhythms that diverge from technocratic logics. Within temporalities not governed by state or capital, urban spaces are collectively reproduced from below, positioning spatial production as a bottom-up process rather than a top-down imposition.
The study contributes theoretically by advancing Lefebvre’s rhythmanalysis, Urry’s notion of differential mobility, and Gandy’s political ecology of infrastructure within the context of Global South cities. By foregrounding time as a critical analytical lens, the research expands our understanding of how power operates temporally in urban life, and how residents negotiate this power through their everyday rhythms.
Ultimately, this research offers a new perspective for interpreting urban dynamics—not only through spatiality but also through socially produced temporalities.
Abstract:The conflict surrounding the Rempang Eco-City National Strategic Project (PSN) on Rempang Island, Batam City, Riau Islands Province, is one of the most complex development policy crises of the past decade. This study analyzes…
lyzes the neglected environmental disaster mitigation dimensions in the acceleration of the Rempang Eco-City PSN from nine environmental perspectives, while evaluating whether the cancellation of this strategic development policy is a normatively and empirically justifiable choice. Using a qualitative research approach with a case study design, the study combines regulatory analysis based on legal documents including Laws, Government Regulations, Presidential Regulations, Ministerial Regulations, Environmental Impact Assessment (AMDAL) documents, and the Batam City Spatial Plan (RTRW) with field data from secondary sources compiled between 2023–2025. The findings reveal four main conclusions: (1) regulatory incoherence exists between Permenko Ekuin No. 7/2023 and Law No. 32/2009 on Environmental Protection and Management (PPLH) as well as Law No. 27/2007 on Coastal Zone Management; (2) the AMDAL process was carried out procedurally without participatory substance and was only initiated after the conflict erupted; (3) environmental impacts including threats of deforestation of protected forests, mangrove ecosystem degradation, and sea sand exploitation have not been adequately mitigated; and (4) resistance from approximately 80% of affected residents indicates a failure of the Free, Prior, and Informed Consent (FPIC) principle. The most recent development shows that through Presidential Regulation (Perpres) No. 12 of 2025, signed by President Prabowo Subianto on February 10, 2025, Rempang Eco-City is no longer listed among the 77 national strategic projects. This study recommends a comprehensive policy evaluation for Rempang Island development based on an independent AMDAL review, fulfillment of the rights of the Malay indigenous community, and a moratorium on all construction activities until legal certainty is established.
Abstract:Karstification is the dominant geological process controlling groundwater circulation and permeability in carbonate aquifers. Through the dissolution of carbonate rocks, karst processes create highly heterogeneous systems…
s characterized by fractures, conduits, and interconnected channel networks that significantly influence groundwater flow dynamics. This literature review aims to synthesize current knowledge regarding the effects of karst on water circulation and permeability in carbonate aquifers based on hydrogeological, hydrochemical, geophysical, and numerical modeling studies from various regions worldwide. The review shows that karstification substantially enhances hydraulic conductivity and produces complex flow regimes ranging from diffuse fracture flow to turbulent conduit flow. The epikarst zone plays an important role in regulating infiltration and recharge distribution, while tectonic structures such as faults and fractures strongly control groundwater pathways and aquifer compartmentalization. Karst aquifers also exhibit strong spatial variability in permeability, making groundwater flow and contaminant transport difficult to predict using conventional hydrogeological approaches. In addition, the integration of equivalent porous medium (EPM), discrete fracture network (DFN), and conduit network (CN) models is essential for accurately representing karst aquifer behavior. Understanding the influence of karstification on groundwater circulation is therefore crucial for sustainable groundwater management and aquifer vulnerability assessment, particularly in regions facing increasing water demand and climate change pressures.
Abstract:The growing emphasis on sustainable urban mobility has positioned electric vehicles (EVs) as a strategic component of transport transformation, particularly in developing cities with constrained infrastructure systems. One…
ne of the key challenges in supporting EV adoption is the provision of accessible charging infrastructure, which is closely related to user perception of acceptable service distance. This study aims to determine the optimal service distance of Electric Vehicle Charging Stations (EVCS) based on user preferences in Pekanbaru City, Indonesia, and to explore its implications for spatial planning. A quantitative approach was employed using a questionnaire survey of 51 respondents distributed across 15 administrative districts. All respondents were non-EV users, representing potential adopters in the early stage of transition. The survey captured preferred EVCS distance using interval-based categories, along with respondents’ awareness and intention toward EV adoption. The results indicate that the dominant preferred distance falls within the 2–4 km range, with an estimated mean of 3.08 km and a standard deviation of 1.98 km, resulting in an effective range of approximately 1–5 km. Considering urban road network constraints and detour factors, this range is further adjusted to 3–6 km to reflect more realistic travel conditions. These findings suggest that a relatively dense and accessible charging network is required to reduce range anxiety and support EV adoption. From a spatial planning perspective, a 4 km service threshold is proposed as a practical reference for EVCS deployment, representing the central tendency of user preferences within the adjusted range. This study highlights the importance of integrating user-based spatial parameters into infrastructure planning and contributes to the literature by emphasizing the role of perceived accessibility in shaping EV infrastructure demand in developing urban contexts.

tems (LMS), and abundant online learning resources. In this context, university students are required to possess adequate digital literacy, particularly in software- and spatial-analysis-based courses such as Geographic Information Systems (GIS), which is a key course in the Environmental Engineering curriculum. This study aimed to analyze the effect of digital literacy on students’ learning outcomes in a GIS course offered in the Environmental Engineering Study Program at Universitas Hamzanwadi. A quantitative approach with a correlational design was employed. The population consisted of students enrolled in the GIS course in the odd semester of the 2024/2025 academic year, and all 44 students were taken as the sample using a saturated sampling technique. Digital literacy was measured using a Likert-scale questionnaire (1–5) covering technical skills, information search and evaluation, information management, online communication and collaboration, and ethical use of digital media, while learning outcomes were obtained from the final course grades.
The data analysis showed that the mean score of students’ digital literacy was 3.6 (moderately high), with a standard deviation of 0.45, whereas the mean GIS course grade was 78.5 with a standard deviation of 6.8. Pearson correlation analysis indicated a positive and significant relationship between digital literacy and learning outcomes (r = 0.62; p < 0.01). Simple linear regression further revealed that digital literacy accounted for approximately 38% of the variance in learning outcomes (R² = 0.38), with the regression equation Ŷ = 52.3 + 7.3X. These findings highlight the importance of strengthening students’ digital literacy in GIS instruction through training, project-based assignments, and the optimal utilization of Learning Management Systems.
Abstract:This study aims to analyze population dynamics and the challenges of sustainable development in Indonesia from a social, economic, and environmental perspective. Population dynamics, including population growth, urbanization,…
tion, internal migration, and changes in demographic structure, have become determining factors in the success of development. The method used is a qualitative approach with a literature review sourced from official documents, scientific journals, and reports from international institutions. The results show that rapid population growth and uncontrolled urbanization have led to spatial inequality, reduced green open space, pressure on public infrastructure, and increased environmental degradation. Furthermore, unpreparedness in spatial planning and weak integration of population data into development policies exacerbate socio-economic imbalances between regions. The shift in demographic structure toward a predominance of the productive age group presents the opportunity for a demographic bonus, but also the risk of a demographic burden if not balanced by improvements in the quality of human resources. This study emphasizes that successful sustainable development requires data-driven, gender-equitable, environmentally friendly, and participatory population policies. The integration of technologies such as Geographic Information Systems (GIS) and spatial analysis is a strategic step in realizing inclusive, adaptive, and sustainable development for future generations.
