Abstract

Kampwolker is one of the areas included in the Cyclops nature reserve, therefore all components of the ecosystem need to be protected and their development occurs naturally. However, nowadays there have been community activities that have caused land changes. The research method used in this research is mixed method and there are two data analysis techniques used, namely, overlay data analysis techniques and quantitative data analysis techniques. Overlay data analysis can produce land changes that increase every year, while quantitative data analysis techniques can produce community activities that have an impact on the Kampwolker protected area and efforts to overcome these problems. Land changes occur due to community activities. The impact is that the water discharge has decreased so that the Kampwolker river experiences drought.

Abstract

This study aims to analyze the spatial distribution patterns and business characteristics of Coffee Shops in Wai Mhorock Sub-district, Abepura District, Jayapura City. The rapid growth of Coffee Shops in this area is influenced by its strategic location, situated near educational institutions, shopping centers, and social activity hubs. The research employs a quantitative approach with spatial mapping techniques using Geographic Information Systems (GIS) and field surveys to identify the characteristics of each business. The results show that the spatial distribution of Coffee Shops in Wai Mhorock tends to be clustered, with a high concentration along main roads and community activity centers. The characteristics of the businesses vary in terms of venue concept, types of menus offered, operational hours, supporting facilities, and target consumers. Most Coffee Shops target young people such as students and university attendees by offering a cozy atmosphere and free internet access. In conclusion, understanding the spatial patterns and business characteristics of Coffee Shops can serve as a foundation for sustainable urban spatial planning and business development. This study also provides recommendations for entrepreneurs and local governments to consider location, accessibility, and environmental impacts in managing commercial space.

Abstract

This study aims to assess the feasibility of facilities and infrastructure at the Dok IX Flats (Rumah Susun) located in Tanjung Ria Sub-district, North Jayapura District, Jayapura City, based on the Indonesian National Standard (SNI) 03-1733-2004, as well as residents’ perceptions. The research uses a mixed methods approach, combining quantitative and qualitative methods. Data were collected through field observations and questionnaires distributed to 43 respondents using the Likert scale. The results show that, in general, the housing complex is considered feasible, with an average score of 70 or 76.1%. Facilities such as education, health, worship, green open space, road access, and drainage are considered adequate. However, inconsistencies were found in the disaster mitigation system. Although categorized as "Feasible," field observations revealed damaged evacuation routes and the absence of essential firefighting equipment (APAR). In conclusion, the Dok IX Flats are generally suitable for habitation, but urgent improvements are needed, particularly in the disaster mitigation aspect, to ensure the safety and comfort of the residents.

Abstract

Crime represents unlawful acts contrary to societal norms. In 2021, Jayapura City experienced a high number of criminal cases, predominantly involving crimes against property and goods. This study maps the distribution of crime rates and identifies contributing factors in Jayapura City using the K-Means Clustering and Analytical Hierarchy Process (AHP) methods. K-Means Clustering analysis revealed five crime levels: high, relatively high, moderate, quite low, and low. North Jayapura District exhibited the highest crime rates among all districts, with Gurabesi Village similarly showing elevated criminal activity. The clustering results were subsequently mapped to visualize the spatial distribution patterns of crime. AHP analysis identified economic factors and low educational attainment as primary contributors to criminal behavior in Jayapura City. Among various intervention alternatives, job creation emerged as the most effective strategy, achieving the highest comparative value for simultaneously improving educational quality and security conditions. These findings provide crucial insights for law enforcement agencies and policymakers to develop targeted crime prevention strategies, focusing on economic development and educational improvement in high-risk areas, particularly North Jayapura District and Gurabesi Village.

Abstract

This study examines the effectiveness of urban city parks as a form of Urban Green Open Space (UGOS) in Jayapura City, focusing on Imbi Park (2,347.20 m²) and Mesran Park (2,122.88 m²). A mixed-methods approach combined direct observation of six park characteristics with a questionnaire-based rating-scale assessment of nineteen functional variables covering socio-cultural, aesthetic, and economic functions. Data were collected from 100 visitors and 31 street vendors, and analyzed using descriptive statistics and scoring analysis in accordance with Minister of Public Works Regulation No. 05/PRT/M/2008. Both parks share three dominant functions socio-cultural, aesthetic, and economic while the ecological function is present but not dominant. For Imbi Park, the socio-cultural function was moderately effective (1.8–2.0), aesthetic moderately effective to effective (2.4–2.6), and economic moderately effective (1.8–1.9). For Mesran Park, socio-cultural and aesthetic functions were moderately effective (1.8–2.2), while the economic function was ineffective (1.6). The main weaknesses across both parks are the unavailability of security posts and limited diversity of park-produce-based economic activities. The study recommends developing supporting facilities and a park-profile web portal to improve effectiveness and information accessibility.

Abstract

Households in Yabansai Urban Village, Heram District, Jayapura City, experience recurrent clean-water shortages as the Kampwolker River, the raw-water source of PDAM UPP Waena, discharges decline. This study examines the supply-demand balance of clean water and community adaptation strategies in meeting household water needs. Demand was calculated using the Directorate General of Cipta Karya (1998) standard for a subdistrict town (90-100 L/person/day). Primary data were collected through semi-structured interviews with 60 households across 12 RWs and two PDAM staff, supported by field observations of the intake, distribution network, boreholes, and household storage facilities. The results show that Yabansai's demand is 1,582,650-1,758,500 L/day, while PDAM UPP Waena's net distribution capacity is 2,268,000 L/day in the wet season and 1,008,000 L/day in the dry season. Because this capacity serves several areas, the wet-season surplus is only nominal, and the dry-season capacity is insufficient even for Yabansai alone. Despite this structural shortfall, 61.7% of respondents rate water availability as "Very Sufficient": community practices (water storage, rainwater harvesting, boreholes, water purchase) form an adaptive equilibrium that sustains daily activities but remains costly and vulnerable. The study recommends watershed rehabilitation, source diversification, distribution transparency, and network extension to unserved RWs.

Abstract

This study examines land-use transformation in Hamadi Rawa I, Jayapura City, focusing on the shift from water catchment to built-up land during 2015–2025. The research employs a mixed-methods approach, combining analysis of Google Earth imagery with interviews with community, government, and academic stakeholders. Findings show the catchment area shrank by 48% (from 17% to 8% of the total area), decreasing from 21.36 ha to 11.20 ha. The built-up area increased by 28.1%, from 70.78 ha to 90.67 ha, with residential development driving most of this growth (51.1%). Three spatial transformation patterns emerged: ecological fragmentation, linear service sector development, and concentric settlement patterns. Idle land was also identified as a phenomenon that damages ecological functions without providing a productive benefit. The conversion was driven by physical-natural factors (basin topography), economic factors (market proximity), socio-demographic factors (urbanization), and especially institutional factors. Customary land transactions outside state control created a governance dilemma between humanity and public order. The study recommends a proactive-collaborative approach with three key instruments: (1) Zero-Reclamation with Adaptive Permitting for stilt structures; (2) fiscal intervention using Idle Land Tax and Payment for Ecosystem Services; and (3) a Participatory Spatial Control Task Force integrating government and customary authorities (Ondoafi).

Abstract

This study aims to identify the management system for Taman Imbi by the Department of Public Works and Public Housing (Dinas PUPR) and to analyze its comfort level based on the perceptions of park visitors and street vendors (PKL). Taman Imbi, managed by the PUPR Service (Section for Environmental Management and Parks), is one of the main urban parks in the city center of North Jayapura District. The research uses a descriptive, qualitative approach combined with Likert-scale analysis. Primary data were obtained from questionnaires distributed to 100 park visitors and 10 business actors (PKL) operating around the park. Eight comfort indicators were assessed, based on Hakim (2003): aesthetics, cleanliness, safety, noise, circulation, aroma, physical form, and climate/natural forces. Results indicate that, based on visitor perceptions, the overall comfort level was 56.0% (fairly good), while PKL perceptions were 64.4% (good). Among all indicators, circulation scored the lowest for visitors (46.2%), particularly ease of access. Aroma/odor scored the highest for PKL (80.0%). The study recommends rehabilitating park facilities, reactivating security posts, improving pedestrian and parking access, and clarifying spatial zoning for economic and community activities in the park.

Abstract

Ciberi Beach is a tourist area in Enggros Village, Abepura District, Jayapura City, with significant development potential that draws on its natural resources and local wisdom. This study aims to identify internal and external factors influencing the development of the tourism area and to formulate appropriate development strategies using SWOT analysis. The research employs a mixed-methods approach, combining qualitative and quantitative techniques, with data collected through field observations, in-depth interviews, and questionnaires distributed to 25 visitors. The findings show that the main strengths are unspoiled natural scenery and community friendliness, while the main weaknesses include inadequate public facilities and poor road access. Key opportunities include ecotourism potential and policy support for spatial planning, while threats include coastal abrasion and unmanaged waste. Based on the SWOT matrix, the strategic position falls in Quadrant I (X = 0.31; Y = 0.51), supporting an aggressive SO strategy. Priority strategies include community-based ecotourism development, digital promotion, collaborative partnerships with universities and NGOs, and regulatory strengthening for sustainable land use. The analysis is grounded in a three-framework theoretical lens comprising the 3A tourism components (Attraction, Accessibility, Amenity), ecotourism principles, and community-based tourism, which together guide the interpretation of SWOT findings and the formulation of strategy.
