The existence of Mount Merapi in Sleman Regency makes the agricultural land in the area fertile and that becomes the attraction for humans to occupy the region. A high population growth will lead to the residents demand of the availability built-up land higher, that makes the environmental carrying cappacity in Sleman Regency decrease. However, the volcanic activity of Mount Merapi becomes a threat to the people who live in the area of Disaster Prone Areas of Mount Merapi. Predictions on the availability of land as well as the relation to the disaster-prone areas, and the carrying capacity of the environment needs to be done. 2007 – 2017 population data and Landsat 7 ETM + 2007, 2012, and Landsat 8 OLI 2017 imagery will be used in this research as variable in the spatial dynamics model. Meanwhile, physical and accesibility data such as slope, distance from the river, distance from protected area, distance from road, and distance from the center of economic growth will be used as limiting factor of built-up land. Environmental carrying capacity can be observed through a dynamic system model of the relationship between population growth and land availability within the period of 2007 - 2100, then made into the spatial dynamics model to know it’s spatial stance. The results of this model show that built-up land increasing every year, packed areas that are suitable for built-up land first, then encroach on areas which not suitable for built-up land and Mount-Merapi Disaster-Prone Areas.

Kabupaten Kepulauan Meranti terletak berdekatan dengan Batam yang dikembangkan sebagai pusat pertumbuhan yang disebut sebagai Kawasan Perdagangan Bebas dan Pelabuhan Bebas. Pengembangan Batam tersebut diharapkan memberikan dampak sebar bagi wilayah sekitarnya (hinterland), khususnya Meranti. Berdasarkan latar belakang tersebut, penelitian ini bertujuan untuk mengetahui dampak posisi Meranti tersebut terhadap pembangunannya. Selain itu, penelitian ini bertujuan untuk menentukan sektor basis apa yang sebaiknya diprioritaskan untuk dikembangkan dan dimana sebaiknya sektor tersebut dikembangkan di Meranti. Untuk menjawab pertanyaan tersebut, penelitian ini menggunakan metode kuantitatif dengan menggunakan analisis gravitasi dan location quotient. Selain itu, analisis spasial dilakukan untuk menentukan lokasi pengembangan sektor-sektor basis di Meranti. Kemudian, hasil tersebut dibandingkan dengan rencana pembangunan (RPJP dan RPJMD Kabupaten Meranti). Penelitian ini menemukan bahwa pengembangan Batam sebagai pusat pertumbuhan belum mampu memberikan dampak sebar signifikan bagi Meranti sehingga perlu di dikembangkan sektor basis berikut: transportasi dan pergudangan, pertanian, dan industri pengolahan.

The existence of Mount Merapi in Sleman Regency makes the agricultural land so fertile and that becomes the attraction for humans to occupy the region. A high population growth will lead to the people demand of the availability built-up land higher. However, the volcanic activity of Mount Merapi becomes a threat to the people who live in the area of Disaster Prone Areas of Mount Merapi. This study presented an application of multi criteria analysis technique as an approach to deal with the built-up land suitability. Physical and accessibility data such as slope, landform, distance from the river, distance from road, distance from the center of economic activities, and Mount Merapi disaster-prone area will be used as limiting factor of built-up land. The result shows that the majority of Sleman Regency is suitable for built-up land.

The presence of healthcare facilities is quite essential to provide good healthcare services in a particular area, however, the existence of healthcare facilities is not evenly distributed in Cianjur Regency. This condition leads to the disparities of healthcare facilities across the Cianjur Regency. In this paper, we aim to measure and map the spatial disparities of healthcare facilities using a Two-Step Floating Catchment Analysis (2SFCA). This method can calculate the magnitude of spatial accessibility for healthcare facilities by formulating the travel time threshold and the quality of healthcare facilities across the study area. This research shows the result that the spatial accessibility of healthcare facilities in the Cianjur Regency is not evenly distributed across the districts. The spatial accessibility value resulted from 2SFCA is ranging from 0- 3.97. A low value indicates low spatial accessibility, while a higher value shows good accessibility. The majority of districts in the Cianjur Regency have the spatial accessibility value 0-0.5 (86%). Meanwhile, only a few have the higher value; value 0.5-0.99 as much as 6.6%, 0.99-1.49 as 3.3%, and 3.48-3.97 has a percentage of 3.3%. Also, this analysis results in the cluster of good spatial accessibility in healthcare facilities, namely the Pagelaran District and Cipanas District. Interestingly, the downtown of Cianjur Regency has lower spatial accessibility compared to both areas.
