Judul: Analysis of Land Cover Changes and Local Sustainability Index in Cianjur Regency
Abstrak: Secara geografis Wilayah Cianjur berada di antara Jakarta dan Bandung. Kekuatan ekspansi perkotaan dari wilayah Jakarta Metropolitan Area dan Bandung Metropolitan Area telah mempengaruhi perubahan tutupan lahan dan perkembangan wilayah di Kabupaten Cianjur. Penelitian ini bertujuan untuk (1) mengidentifikasi jenis tutupan lahan dan pola perubahan tutupan lahan; (2) menghitung nilai indeks keberlanjutan lokal (IKL) yang ditinjau dari 3 dimensi yaitu ekonomi, sosial dan lingkungan di masing-masing desa; (3) menganalisis pola sebaran asosiasi spasial nilai indeks keberlanjutan lokal (IKL) untuk masingmasing dimensi; (4) menganalisis tipologi desa berdasarkan nilai IKL masingmasing dimensi ekonomi, sosial dan lingkungan dan luas pemukiman. Penelitian ini menggunakan data tutupan lahan, data potensi desa, dokumen kabupaten dalam angka dan peta administrasi Kabupaten Cianjur. Metode yang digunakan adalah Overlay, Factor Analysis (FA), Local Indicator of Spatial Autocorrelation (LISA) dan K-means cluster. Hasil penelitian menunjukkan perubahan tutupan lahan lahan terbesar terjadi pada sawah dari 77270,4 ha pada tahun 2011 menjadi 48075,8 ha pada tahun 2021 dengan total penurunan luasan sekitar 29212,6 ha. Pertanian lahan kering mengalami penambahan luasan sangat besar sebanyak 43428,5 ha diikuti dengan pemukiman bertambah sebesar 4889,7 ha. Secara umum berdasarkan hasil IKL, IKL lingkungan kategori tinggi dan sangat tinggi mengalami penurunan jumlah desa, sedangkan IKL sosial dan ekonomi kategori tinggi dan sangat tinggi mengalami peningkatan jumlah desa. Desa-desa dengan kelestarian lingkungan tinggi dominan di WP selatan sedangkan desa-desa dengan kesejahteraan sosial dan pertumbuhan ekonomi tinggi terkonsentrasi di WP Utara yaitu Kecamatan Cianjur, Kecamatan Pacet dan Kecamatan Cipanas. Wilayah di Kabupaten Cianjur terbagi menjadi 4 klaster. Klaster 1 merupakan desa perkotaan; Klaster 2 merupakan desa yang sedang berkembang sosial dan ekonominya; Klaster 3 merupakan wilayah desa dengan kelestarian lingkungan tinggi; dan Klaster 4 merupakan desa tertinggal., Geographically, the Cianjur Regency is located between Jakarta and Bandung. The urban expansion of the Jakarta Metropolitan Area and the Bandung Metropolitan Area has influenced land cover and growth in Cianjur Regency. This research aims to (1) identify types of land cover and patterns of land cover changes; (2) calculate the local sustainability index (LSI) value in terms of 3 dimensions, namely economic, social, and environmental, in each village; (3) analyze the distribution pattern of spatial associations of local sustainability index (LSI) values for each dimension, and (4) analyzing regional typologies based on LSI values for each economic, social and environmental dimension and built up area. This research utilizes various data sources, including land cover data, village potential data (PODES), regency documents, and administrative maps of Cianjur Regency. The methods employed include overlay, Factor Analysis (FA), Local Indicator of Spatial Autocorrelation (LISA), and K-means cluster. The research results show the most extensive land cover changes occurred in rice fields, from 77270.4 ha in 2011 to 48075.8 ha in 2021, with a total decrease in area of around 29212.6 ha. Dry agricultural land experienced a substantial increase of 43,428.5 ha, followed by an increase in built-up area of 4,889.7 ha. In general, based on the results of the LSI, environmental LSI in the high and very high categories experienced a decrease in the number of villages. In contrast, social and economic LSI in the high

Judul: Pemodelan Penggunaan Lahan untuk Permukiman di Kabupaten Cianjur
Abstrak: Cianjur regency is one of many regencies affected by the expansion of Jakarta and Bandung Metropolitan. Consequently, people are migrating to the cities caused an increasing population. It leads to experiencing uncontrolled advancement and arising problems. One of them is the raising land demand for settlement development, but the land is limited. Therefore, there is a need to address these particularities. This research aimed to model land utilization for settlement. To achieve the main aim, three specific objectives have arisen. First is identified land suitability for settlement. Second, delineated land availability for settlement. Third, allocated land for settlement based on demand. The methodology used is Multi-criteria evaluation (MCE) and geographical information system (GIS). They were collaborated to define the suitability class for settlement. The analytical hierarchy process (AHP) sets the criteria's weight using a pairwise comparison matrix. Overlapping the Land-use existing, Spatial plan or in Bahasa is Rencana Tata Ruang Wilayah (RTRW) and Sustainable food farm or in Bahasa is Lahan Pertanian Pangan Berkelanjutan (LP2B) were carried out to delineate the land available for settlement in 2030. In the end, a priority matrix has been built for allocating the demand of settlement. Two critical variables were considered in this stage: land suitability class and distance from the activity center. The AHP result showed that the most crucial consideration to define the land suitability class for settlement in Cianjur regency came from the disaster consideration. There are landslide and flood-risk. When the preferences between developers, academics, and government are separated, a different result is found. Developers think that the essential criterion is the accessibility consideration, especially distance to the nearest road. Meanwhile, academics and governments think that disaster consideration is the most important. Suitability classes for settlement in Cianjur Regency are: highly suitable (S1) 36%, suitable (S2) 7%, marginally suitable (S3) 44%, and not suitable (N) 14%. The land availability for settlement development decreases after implementing the Spatial plan and Sustainable food farm regulations. Land availability for settlement of Cianjur regency in 2030 is only 81 km2 or 2% of the total area. Allocation of the land demand for settlement focuses on two sub-districts in Cianjur regency: Sukaresmi and Agrabinta sub-districts. These two are representative of each cluster of the region. Sukaresmi presented Northern Cianjur, and Agrabinta presented the Southern of Cianjur. Allocation for settlement in 2030 in Sukaresmi will utilize the land with Priority one, Priority two, and Priority three for Business as usual (BAU), tradition protection, Market forces, and Horizontal expansion scenario. For Vertical expansion, it will utilize the land with Priority one and Priority two. The allocation of land demand for settlement in Agrabinta under Business, as usual, Market forces, and Horizontal expansion will use land with Priority one, two, and three. The Tradition protection will utilize land with Priority one and two, while the Vertical expansion scenario will only utilize the land with Priority one. This study gave an overview of the land suitability, availability, and the projected land for allocating the land for settlement based on five different scenarios. The marginally suitable class for settlement dominates Cianjur regency.
