Jakarta and Bandung metropolitan areas in Indonesia are experiencing urban expansion, which makes these two metropolitan areas increasingly connected by corridors to become one mega-urban. Karawang and Purwakarta Regencies are part of the Jakarta-Bandung corridor area which then triggers the urban physical development. This study aims to 1) Determine the level of service facilities in Karawang and Purwakarta Regencies; 2) Identify the changes in built-up and paddy fields Land Use/Land Cover (LULC) of Karawang and Purwakarta Regency based on existing and future conditions, and 3) Propose recommendations to control the urban physical development in Karawang and Purwakarta Regency. Analysis of level service facilities was carried out by using the scalogram method. Changes of built-up and paddy fields LULC in the existing and future conditions (projected using the CA-Markov method) are based on LULC of 2005, 2010 and 2018. Recommendations are given based on the grouping of villages with the same characteristics using the quantitative zoning method. Results showed the village development index in 2018 as the level of service facilities indicators, has a high or more developed value in the area around the connecting accessibility route between Jabodetabek and Greater Bandung metropolitan area. Changes in built-up and paddy fields LULC also the same trend as the village development index that is characterized by a fairly large increase in the area of built-up LULC in Karawang and Purwakarta Regencies. Recommendations are given to address specific problems that exist in each village group formed based on the spatial clustering method result.

Identification of root causes and associated impacts of land fragmentation is necessary to reduce future fragmentation and mitigate its impacts. Thus, the purpose of this study was to explore the causes and impacts of land fragmentation in a purposively selected coastal Upazila (sub-district) of Bangladesh. This study is carried out mainly based on the collected information from the individual representative of the selected 133 households. It discloses that most of the households observed the land fragmentation during their possession because of rapid population growth and breaking the joint/extended families into nuclear families. In fact, land fragmentation can increase or decrease a particular land use type. However, the results of this research confirm that there are no significant (p >0.07, based on the number of households) associations found between increasing and decreasing homestead land. In contrast, the number of households with cropland significantly (p <0.0001) decreased, whereas the number of households having wetlands significantly (p <0.04) increased. The surveyed households have been practicing high-yielding varieties of crops, using biofertilizers, possessing new land, and changing their income sources for adapting to new land use behavior. The surveyed villagers opine that the land fragmentation problem could be managed by encouraging people living with extended/joint families, vertical use of land, adopting land use policy, etc. The results of this community-reported study can be used to mitigate the impacts of land fragmentation in the coastal rural area of Bangladesh.

Catch fluctuation of Sardinella lemuru in the Bali Strait in the period 2007 - 2019 shows a significant decrease. The fishermen of this area demanded information on the Potential Fishing Zone (PFZ) specifically targeted for Sardinella lemuru beyond their traditional. PFZ will be very helpful, especially during the famine years. Identification of a Potential Fishing Zone (PFZ) is highly important for increased fishing yields and also reduced fishing time for fishermen. Bali strait is dominated by Sardinella lemuru and contributes 16,2% of the total small pelagic fishery production in Fisheries Management Area (FMA) 573. Bali Strait also supports the fishing industry in Muncar (Banyuwangi-East Java) and Pengambengan (Jembrana-Bali). This study will produce a special PFZ for Sardinella lemuru that is not yet available in Indonesia by using remotely sensed and observer data. Here, we apply the Empirical Cumulative Distribution Function (ECDF) algorithm approach for Sardinella lemuru detection. ECDF was developed using Sea Surface Temperature (SST) and Chlorophyll-a (Chl-a) data from Aqua MODIS and extracted according to observer data during 2011-2014. PFZ for Sardinella lemuru in Bali strait was affected by 72,8 % Chl-a conditions and 27,2% by SST conditions. The maximum suitable preference for Sardinella lemuru in Bali Strait is Chl-a condition at 0,2 mg/m3 and SST condition at 28,38°C in northwest monsoon, while in southeast monsoon are 0,97 mg/m3 for Chl-a and 25,61°C for SST. ECDF model result has 69,33% accuracy, which shows the result of Sardinella lemuru PFZ has good accuracy.

International migration trajectory is one of the important aspects discussed when viewing the migration culture of a region. The specific types and patterns created are unique and dependent on the length of the migration history. Therefore, this study is aimed to explain the migration history carried out by residents in Ponorogo Regency, East Java Province, and the factors that influence international migration. This is a survey research of 515 international migrants. The results showed that the migration pattern in Ponorogo Regency was divided into one, two, and three destination countries with temporal space-related cultural factors used to determine an important influence on rural households' ability to work abroad. Similar to other studies, age and gender are the two key variables related to migration trajectories in Ponorogo Regency.

The complexity of regional disparity has encouraged viewing this issue from various perspectives, one of which is the role of physical geography in disparity. On Java Island, an observation on the role of geographical aspect is needed due to the spatial sturdiness of disparity. This study aims to provide quantitative proof that differences in the physical geography of Java’s regions account for the persistent regional disparity. We applied two approaches namely correlation and typology, employing data of physical geographical attributes and development level. The methods used were correlation analysis, factor analysis, cluster analysis, and one-way ANOVA. Based on the correlation approach, we found the association of regional development level with terrain ruggedness, soil parent materials, sea depth, elevation, and precipitation. Then, based on endowment-based typology approach, Java’s regions could be grouped into lowland, volcanic, old volcanic, and calcareous dry regions. The two latter performed poorly in all socio-economic indicators examined.

This study is generated by the limited understanding of the actor's power on village-level deliberation. In community-level deliberation, especially for villagers, planning struggles with unbalanced power from involved actors to avoid potential failures due to inappropriate implementation and waste of state finances. Problems from policy formulation results have distorted the consensus. Community-based planning faces different power characteristics displayed by involved actors. However, it seems that this matter's understanding is mostly obtained in Western urban areas context and few have studied it in the rural context, even more, sourced from non-Western and global south practices. Questions arise on the power capabilities each actor has and its implications for the planning formulation results. This article aims to provide an understanding of the actor's position and their source of power. It investigates the power identities of involved actors on the community-level deliberation through a power cube approach. Community-level deliberation in Pematang Tengah village, Indonesian, is used as the case study. Primary data were obtained from interviews with twenty-one respondents, observation, and document analysis during 2018-2020. The result shows that each actor displays a specific power characteristic driving their influences on the planning formulation results. This condition has implications for the construction of the power holder's influence in dominating the deliberation process.

Mangrove forest is a very valuable forest, but despite its benefits mangrove forest continue to be degraded due to human activities. The purpose of this study was to map the distribution and to analyze mangrove forests’ health based on the NDVI vegetation index value and environmental quality. Distribution of mangrove forest health was obtained through the processing of sentinel 2-A satellite imagery in 2020 and field measurements. The environmental quality of the mangrove forest was obtained by processing the physical parameters which are water temperature, water salinity, water pH, and substrate texture using the Ordinary Kriging method. The health of the mangrove forest of Taman Hutan Raya Ngurah Rai is dominated by healthy category mangroves. The health of the mangrove forest worsens when closer to the shore and riverbanks. Mangrove vegetation with good conditions tends to have optimal environmental quality conditions and vice versa.

As one of the largest archipelagic countries in the world, Indonesia has an area of inland waters of 3.11 million km2 and a territorial sea area of 290,000 km2. Indonesia also has 17,504 islands, 34 provinces, and 514 cities/districts. For orderly administration, the government and parliament established Law No. 32/2004 amended by Law No. 23/2014 concerning regional governance. In both laws, there is little regulation on the management of marine areas in the provinces and districts/cities. Since the Law No. 32 of 2004 on amendments became Law No. 23 of 2014, some problems arose, namely vertical references, management authority, and archipelagic provinces or districts/cities. This paper describes the problems and alternative solutions to address the problems caused by the amendments to Law no. 32/2004 into Law no. 23/2014. The method used is to compare the vertical references used by Law no. 32/2004 namely LWL with Law. No. 23/2014 namely HWL. The results of this study recommend that to return to the vertical reference used, it must return to HWL by UNCLOS 1982. In addition, the authority for managing marine areas must also be returned to the district and city governments and there is recognition of districts/cities and archipelagic provinces that are not separated by the sea.

Participatory mapping (PM) method has become an alternative in spatial data collection activities for various mapping activities, including updating data on Rural & Urban Land and Building Tax (PBB-P2). From several experiences in PM application, various quality results have been found. Differences in the levels of spatial abilities of PM actors are assumed to affect the quality levels of PM results. Therefore, this study aimed to determine the effects of spatial abilities on the quality of spatial data generated in PM activities. It consisted of several stages of preparing instruments for measuring spatial abilities, collecting spatial data through PM, and correlation analysis. The instrument used to measure the levels of spatial abilities of 28 subvillage chiefs was the Purdue Spatial Visualization Test. The quality of PBB-P2 spatial data in 28 subvillages was randomly selected and assessed in terms of position, area, and geometric accuracies with reference to the land registration map from National Land Agency. Results indicated a positive correlation between the visual spatial ability and the spatial data quality of the PM results with a value of r = 0.823. Our findings are expected to be used as references for parties who carry out PM activities to be able to plan such activities.

Infrastructure development is critical to the success of economic growth policies. Remote sensing and GIS tools have an important role to play in the development of various urban infrastructures. Due to the rapid growth of urban population and urbanization, it is necessary to find out the site's suitability for sustainable urban development. The main aim of the study is to study the growth and trend of urbanization, as well as to find out the suitable sites for further urban development in northern Punjab, along the river Jhelum, Pakistan. The study illustrates the use of geographic information system (GIS) and Remote Sensing based techniques i.e. Human Natural Environment Index (HNEI) applied with a foundation of Relief Degree of Land Surface (RDLS), Temperature Humidity Index (THI), Water Resource Index (WRI), and Land Cover Index (LCI) for selection of the suitable site for urban settlements along river Jhelum, Pakistan. For this purpose, Toposheet and Landsat satellite data were used to generate various thematic layers using ArcGIS software. The results were generated in form of five categories i.e., highly suitable, moderately suitable, relatively low suitable, low suitable, and non-suitable. The final results indicated that district Sargodha is most suitable for long-term sustainable urban settlements favored by relief, climate, water availability, land cover scenario, and flood hazard-free area. Eventually, a site suitability map is prepared for further urban development. The present study allows the local people as well as urban planners for the appropriate plans of land use planning in sustainable urban development.
{"title":"Site Suitability Analysis for Urban Settlements along River Jhelum, Pakistan using GIS and Remote Sensing Techniques","authors":"S. Zia, M. Mohsin, Muhammad Nasar-u-Minallah, Ayshah Hanif","doi":"10.22146/ijg.72354","DOIUrl":"https://doi.org/10.22146/ijg.72354","url":null,"abstract":"Infrastructure development is critical to the success of economic growth policies. Remote sensing and GIS tools have an important role to play in the development of various urban infrastructures. Due to the rapid growth of urban population and urbanization, it is necessary to find out the site's suitability for sustainable urban development. The main aim of the study is to study the growth and trend of urbanization, as well as to find out the suitable sites for further urban development in northern Punjab, along the river Jhelum, Pakistan. The study illustrates the use of geographic information system (GIS) and Remote Sensing based techniques i.e. Human Natural Environment Index (HNEI) applied with a foundation of Relief Degree of Land Surface (RDLS), Temperature Humidity Index (THI), Water Resource Index (WRI), and Land Cover Index (LCI) for selection of the suitable site for urban settlements along river Jhelum, Pakistan. For this purpose, Toposheet and Landsat satellite data were used to generate various thematic layers using ArcGIS software. The results were generated in form of five categories i.e., highly suitable, moderately suitable, relatively low suitable, low suitable, and non-suitable. The final results indicated that district Sargodha is most suitable for long-term sustainable urban settlements favored by relief, climate, water availability, land cover scenario, and flood hazard-free area. Eventually, a site suitability map is prepared for further urban development.
