Abstract

As regulated in Law No. 26 of 2007 concerning Spatial Planning, the urban spatial structure is an arrangement of settlement centres and infrastructure networks that support socio-economic activities through hierarchical functional relationships. In Tegal City, one of the crucial infrastructure elements is the road network, especially the North Coast national route, commonly called the Pantura Route. The Pantura Route strategically affects urban mobility and connectivity between regions. Its location in the city centre makes this route an important arterial corridor connecting major cities on Java Island, such as the Jakarta-Tegal-Purwokerto-Yogyakarta-Surabaya route. However, the high intensity of land use for economic, social, and educational activities has caused various problems, such as traffic accidents. In 2018, 59% of accidents occurred along this route, although this route only covers 13% of the total length of roads in Tegal City. Other problems include limited road infrastructure, physical damage to roads, and low road accessibility, which are also supporting factors. Important local-scale activities along the Pantura route, such as schools, health centres, and trade activities, raise concerns regarding the suitability of spatial structures and safety, especially when compared to national Standards (SNI 03-1733-2004). The method used in this study uses primary and secondary surveys and qualitative descriptive analysis, namely content analysis. The results of this study indicate that the deviation of spatial structures that occur in Tegal City is more than 50% seen from the existence of educational facilities (elementary and junior high schools), health facilities (health centres), and markets with a local scale that are not appropriate along the Pantura route. With regional authority within the framework of Law No. 23 of 2014 concerning Regional Autonomy, the city government is expected to be more active in managing spatial planning, especially spatial structures, so that deviations do not occur. This study aims to evaluate the suitability of the spatial structure of Tegal City by evaluating the function of the road network and the scale of service facilities based on urban environmental planning Standards. The findings of this study are expected to support effective and sustainable spatial planning of Tegal City.

Abstract

The Ijen Crater Nature Tourism Park (Ijen Crater TWA) is one of the tourist destinations with the enchanting blue fire that is quite famous in East Java and even internationally. Ijen Crater has a crater lake with a very low pH, making it one of the largest acidic lakes in the world. It also has significant mineral resource potential in the form of sulfur. Not only that, but Ijen Crater is also part of the Ijen UNESCO Global Geopark. The Ijen Crater TWA is administratively located in Bondowoso and Banyuwangi Regencies, but its management is carried out by the Natural Resources Conservation Agency (BKSDA). The distribution of economic benefits tends to be unbalanced because direct fees in the form of entrance ticket sales go to the central government as Non-Tax State Revenue (PNBP). The management plan for Ijen Crater TWA is included in several development and spatial planning plans, such as the Spatial Planning (RTRW) of Bondowoso Regency, the Spatial Planning of Banyuwangi Regency, and the Long-Term Management Plan for Ijen Crater TWA. Based on these conditions, research was conducted on the typology of stakeholder interactions and the factors influencing their management using a qualitative abductive approach and pattern-matching analysis technique. The research aims to identify the interactions occurring in the Ijen Crater TWA area with the various roles held by stakeholders and to identify the factors influencing them. The research results show that the interactions in managing Ijen Crater TWA include coalitions, coordination, cooperation, networking, and coexistence. The findings from the research can be used as a consideration in developing governance strategies in infrastructure planning to spatial planning in conservation areas involving multiple stakeholders.

Abstract

Vegetation dynamics in Jember Regency serve as a crucial indicator of environmental conditions influenced by anthropogenic factors. As a region where the agriculture and forestry sectors play a vital role in the local economy, contributing 25.71% to the Gross Regional Domestic Product (GRDP), monitoring vegetation change is highly important. This study aims to analyze temporal vegetation change in Jember Regency from 2019 to 2024 using Landsat 8 OLI/TIRS imagery processed on the Google Earth Engine cloud computing platform. The methods employed included calculating Normalized Difference Vegetation Index (NDVI), classifying vegetation change hierarchy using the Natural Breaks (Jenks) method, and conducting zonal statistical analysis to compare vegetation density trends between urban and rural areas of Jember Regency. This research revealed a disparity in vegetation density change between rural and urban areas (Patrang, Kaliwates, and Sumbersari Sub-Districts). Urban areas of Jember experienced degradation, with the mean NDVI value decreasing by 8% per year, from 0.500 in 2020 to 0.460 in 2024, indicating the conversion of agricultural/vegetated land into built-up areas. In contrast, rural areas were determined to be relatively stable, with NDVI mean value ranging from 0.584 to o.554 during the same period. Zonal analysis of the vegetation change map showed that more than 12,000 hectares of land underwent vegetation degradation, predominantly in urban areas of Jember Regency. Meanwhile, rural areas around Mount Gambir exhibited stability or increased vegetation density due to sustainable plantation management. These findings provide quantitative evidence of the impact of urbanization on environmental sustainability and emphasize the need for policies that balance development with the conservation of vegetated land to maintain ecological integrity and support the local economic and ecosystem sustainability of Jember Regency.
