Kriminalitas adalah segala macam tindakan yang merugikan secara ekonomis dan psikologis serta merupakan struktur sosial yang dapat berubah dari waktu ke waktu. Peningkatan kriminalitas dapat disebabkan oleh kejadian luar biasa. Perubahan dalam pertemuan korban dan pelaku terjadi seiring mekanisme lingkungan sosial dan kontrol sosial berubah. Kelurahan Damai memiliki tingkat kriminalitas tertinggi di Kota Balikpapan sejak sebelum hingga setelah pandemi COVID-19. Penelitian ini menggunakan SIG dalam memetakan daerah rawan kriminalitas. Analisis selanjutnya mendeteksi indeks Nearest Neighbour untuk mengetahui pola persebaran titik rawan kriminal. Hasil penelitian menunjukkan bahwa secara umum, pola sebaran kriminalitas tetap menyebar sejak sebelum hingga setelah Covid-19. Meskipun demikian, jumlah kriminalitas mengalami peningkatan dengan jumlah tertinggi pada titik waktu setelah Covid-19.

Meningkatnya urbanisasi di Indonesia, khususnya di Kota Balikpapan, menimbulkan tantangan signifikan dalam menuju perkotaan yang berkelanjutan. Salah satunya tantangan pada pengelolaan kampung kota yang merupakan permukiman informal dengan kepadatan tinggi. Penelitian ini memiliki tujuan untuk mengidentifikasi sebaran dan tipologi kampung kota di Kelurahan Baru Ulu, Kota Balikpapan, yang berfokus pada karakteristik fisik, sosial dan ekonomi. Menggunakan pendekatan metode campuran yang menggabungkan analisis spasial dengan penilaian karakteristik sosial ekonomi. Data dikumpulkan melalui survei dan observasi lapangan. Hasil analisis menunjukkan bahwa kampung kota di Kelurahan Baru Ulu terdiri dari tiga tipologi utama: Kampung Atas Air, Kampung Tepi Air, dan Kampung Dataran Rendah. Keberagaman yang ditemukan pada tipologi ini mencerminkan adaptasi masyarakat terhadap kondisi geografis dan sosial ekonomi lokal, serta menyoroti kompleksitas dalam pengelolaan wilayah perkotaan yang berkelanjutan. Temuan ini memberikan dasar empiris bagi pengembangan kebijakan perkotaan yang lebih inklusif dan responsif terhadap kebutuhan spesifik masing-masing tipologi kampung, sejalan dengan tujuan pembangunan berkelanjutan.

East Kalimantan Province is planned as the new national capital city (IKN). Forest and land fires occur regularly every year and their frequency is increasing, especially during the dry season. This research uses secondary data, namely hotspot data. Hotspot data was obtained from the results of the 2012-2022 S-NPP VIIRS image recording. Data analysis in this study used descriptive and statistical analysis. The results of processing and analysis of the distribution of hotspots are overlaid with administrative maps so that the distribution of hotspots in each district in the study area can be identified. The results of the study show that hotspots distribution from the 2012-2022 S-NPP VIIRS image recording in East Kalimantan Province is varies quite a bit in each district. The highest hotspots distribution is in Kutai Kartanegara Regency and the lowest is in Mahakam Ulu and Penajam Paser Utara Regency. The higher number of hotspots is the higher incidence for forest and land fires. The distribution of hotspots needs to be known because it can be a form of early detection and fire mitigation so that the negative impact of fires can be minimized.

Kabupaten Kutai Kartanegara sebagai sentra pertanian tanaman pangan di Kalimantan Timur memberikan dampak positif bagi struktur perekonomian serta berperan sebagai lumbung pangan Provinsi Kalimantan Timur. Selain potensi terdapat permasalahan terkait alih fungsi lahan pertanian yang sulit dihindari. Tujuan dari penelitian ini adalah merumuskan strategi pengendalian alih fungsi lahan pertanian tanaman pangan di Kabupaten Kutai Kartanegara. Penelitian ini menggunakan Citra Satelit 7 ETM+ dan Landsat 8 OLI/TIRS untuk mengetahui perubahan tutupan lahan pertanian pada tahun 2010 – 2020 menggunakan metode spasial (overlay). Kemudian analisis dilanjutkan menggunakan metode Exploratory Factor Analysis (EFA), dimana data yang digunakan adalah produktivitas lahan pertanian, luas kepemilikan lahan pertanian, pendapatan petani, nilai jual lahan pertanian, laju pertumbuhan penduduk, kebijakan perlindungan lahan pertanian, ketersediaan sumber daya air, jumlah tenaga kerja sektor pertanian, biaya produksi pertanian, harga jual komoditas pertanian. Hasil dari analisis tersebut kemudian digunakan sebagai dasar untuk analisis Strenghts, Weaknesses, Opportunities, Threats (SWOT). Temuan penelitian menunjukkan bahwa pada tahun 2020 terjadi perubahan lahan pertanian seluas 53.134,24 ha dari total luas lahan pertanian yang terdapat pada tahun 2010. Lahan pertanian mengalami perubahan menjadi perairan, hutan, perkebunan, lahan terbangun dan lahan terbuka. Faktor yang mendorong alih fungsi lahan pertanian adalah produktivitas lahan pertanian, pendapatan petani, nilai jual lahan pertanian, kebijakan perlindungan lahan pertanian, ketersediaan sumber daya air, biaya produksi pertanian dan harga jual komoditas pertanian. Strategi pengendalian alih fungsi lahan pertanian tanaman pangan menyesuaikan dengan bentuk perubahan lahan yang terjadi. Sehingga strategi yang dirumuskan berkaitan dengan kebijakan pada sektor pertanian, distribusi bantuan sarana dan prasarana pertanian dan peningkatan pengetahuan sektor pertanian.

The rapid growth of critical land in the Mahakam Cascade catchment area has caused environmental damage and land degradation. There was an increase in this critical land during the last ten years in this area. It was recorded that about 15.54% of the critical land area increased from 2013 to 2018. The condition of land degradation continuously occurs due to increased land use complexity, which does not match the characteristics of the land. As a result, the carrying capacity of the land is getting worst. In responding to this condition, it is necessary to have a different instrument to handle these critical lands. This study aims to formulate directions for handling critical land in the Mahakam Cascade DTA based on the direction of critical land zoning. The first stage was to determine the zoning of critical land vulnerability levels to determine critical land zoning using the weighted overlay method. The following stage was to formulate directives on land management and use with zoning regulations using the Delphi analysis method for key stakeholders. The main findings show that six zoning classifications of critical land are divided into three protected and cultivated areas. From these findings, directions are then drawn up for critical handling of land with the concept of zoning regulation covering land use functions (permitted, limited permitted, conditionally permitted, and prohibited). The zoning regulation directive adjusts to the criticality level of the land and its use function as well as conservation and rehabilitation techniques, i.e., civil engineering approach and irrigation, vegetative, infiltration and drainage wells, which have different settings in each zoning criticality level of critical land.

Flash-flood is considered as one of the most common natural disasters in Grenada, a tropical small state island in Caribbean Island. Grenada has several areas which are susceptible to flooding. One of them is Gouyave town which is located in the north-west of Grenada. Its land-use types are highly dominated by green areas, especially in the upper-part of the region. The built-up areas can only be found in the lower-part of Gouyave watershed, near the coastal area. However, there were many land conversions from natural land-use types into built-up areas in the upper-part region. They affected the decrease of water infiltration and the increase of potential run-off, making these areas susceptible to flash-flood. In addition, it is also influenced by the phenomenon of climate change. Changes in extreme temperature increase higher potential of hurricanes or wind-storm, directly related to the potential escalation of flash-flood. To develop effective mitigation strategies, understanding the behavior of flash-flood is required. The purpose of this paper was to observe the behavior of flash-flood in Gouyave watershed in various return periods using OpenLISEM software. It was used to develop and analyse the flash-flood characteristics. The result showed that the climatic condition (rainfall intensity) and land-use are influential to the flash-flood event. Flash-flood occurs in 35 and 100 years return period. Flash-flood inundates Gouyave’s area in long duration, with below 1 m flood depth. The flood propagation time is slow. This condition is also influenced by the narrower and longer of Gouyave basin shape. To develop flash-flood reduction strategies, the overall understanding of flash-flood behavior is important. If the mitigation strategy is adapted to their behavior, the implementation will be more optimum.

New town development as a form of large-scale development is not a new phenomenon, particularly in developing countries. This development mainly takes place in peri-urban areas due to the high pressure caused by the growing population and the lack of facilities and infrastructure in city centres. As an effect, local communities who originally occupied the land often lose their rights over the property their livelihood might have relied on. Property rights can be grouped differently, classified according to different bundles: appropriation, ownership, and formality of rights. This paper investigates to what extent new town development in Indonesia has affected the property rights of local communities, in terms of the transformation of rights and security level. Moreover, it examines to what extent this transformation has been affected by urbanisation pressure. Ample attention is paid to the transformation of various bundles of rights concerning different usage of property, both residential and cultivated land. A total of 252 questionnaires were distributed to three different locations of new towns in Indonesia. A before-after analysis was employed to identify the transformation of the property rights and their security level, followed by multiple linear regression analysis to observe the influence of the urbanisation pressure to the security level. The research reveals that the transformation of property rights of local residents mainly concerns the appropriation rights. The analysis also indicates that there is a tendency that the security level decreases. Statistically, this appears to be affected by urbanisation pressure variables: type of land, land use, and occupation. With this study, we offer on the one hand a conceptual framework for assessing property rights, while on the other hand, we provide empirical evidence regarding the effects of new town development on property rights transformation and its security level.

One of the important aspects in studies on regional potentials and problems is the sectoral issues in a disaster. It is because disaster is an event or series of events, caused whether by natural or unnatural factors that inflict damages and losses to people and the environment. Landak Regency (Kabupaten) is categorized highly disaster-prone region by the National Disaster Management Agency (BNPB). The aim of this research is to identify the disaster-prone area of Kabupaten Landak. The identification is based on assessment variables of multi-hazards that may occur and threat Kabupaten Landak. The analysis has used geographic information systems, scoring and weighting techniques. Disaster vulnerability was measured based on the existing physical aspects, such as land use, land slope, soil type, and others. It is an explorative and evaluative research with a mix of qualitative and quantitative approaches. The results show that there are disaster potential hazards in Landak Regency, such as flood, landslide, cyclone, bushfire, and forest-fire. Each potential hazard has different vulnerability level and different distribution area based on the risk assessment. © 2015 GJGP UNDIP. All rights reserved

The City of Palu, Central Sulawesi is one of the regions in Indonesia which are vulnerable to tsunami and require a preventive action plan and mitigation to reduce potential risks. This study analyzed tsunami inundation zones and their implications regarding disaster mitigation in the city. This study employed quantitative approach using Geographical Information System (GIS) to map tsunami disaster prone areas. Cost Distance was used to model tsunami disaster; spatial analyst and network analyst were used to analyze the level of danger, vulnerability, and risk of tsunami, and also the establishment of evacuation routes. Analysis indicated the followings: (1) The City of Palu has large potential for tsunami inundation, (2) tsunami danger area comprises 9,63% of total city area, (3) tsunami vulnerable area 9,83% of total city area, (4) tsunami risk area 3,83% of total city area, and (5) there are 50 shelters acting as evacuation points and 108 evacuation routes in around the city. The built up area around the coast of Palu Bay area was identified as having high risk of tsunami disaster. Evacuation routes are scattered in the built up areas with the number of routes corresponding to population density.
