Future Scenario for Farmland Abandonment in Karawang
Get PDFLahan berperan penting dalam kehidupan untuk memenuhi kebutuhan makhluk hidup. Namun, ada tren peningkatan yang nyata dalam pengabaian lahan pertanian, yang secara langsung mempengaruhi mata pencaharian dan ketahanan pangan petani. Analisis penginderaan jauh melaporkan bahwa semua kecamatan dan kelurahan di Kabupaten Karawang memiliki lahan terlantar dengan jumlah yang bervariasi dan terseba merata di wilayah tersebut. Studi ini menemukan bahwa jumlah total lahan pertanian yang diabaikan mencapai 28 kali dari yang diklaim oleh Badan Pusat Statistik. Keakuratan produsen 75%, perbedaan definisi, unit data minimum yang dikumpulkan, kepemilikan lahan, dan kemampuan penginderaan jauh untuk membaca semua reflektan bumi adalah jawaban yang mungkin untuk disparitas tersebut. Pembelajaran mesin menginformasikan bahwa tiga variabel penting teratas adalah layanan irigasi, lereng bukit, dan rencana tata ruang yang mendorong pengabaian lahan pertanian. Dengan demikian, mengembangkan layanan irigasi baru untuk mengakses lahan pertanian terpencil dan meninjau tata ruang yang lebih dibutuhkan untuk pertanian adalah skenario yang diusulkan oleh penelitian ini, sementara lereng bukit tetap menjadi kendala.The land plays a significant role in world life to continue its journey and fulfill living things’ needs. However, there is a noticeable increasing trend in farmland abandonment, directly affecting farmers’ livelihood and food security (Paudel et al. 2020). Remote sensing analysis reported that all the districts and subdistricts in Karawang Regency have abandoned land with varying numbers and more distributed more intensely in the hub of the region. The study has discovered that the total number of farmland abandonment is 28 times of the Central Beauaru Statistics has claimed. 75% producer accuracy, terminology, minimum unit data collected, land ownership, and the ability of remote sensing to read all earth reflectan are the possible answer to the disparity. Machine learning informed that the top three essential variables are the irrigation service, the hillside, and the spatial plan that drives farmland abandonment. Thus, developing a new irrigation service to access the remote farmland and reviewing the spatial that have more flavor to the agriculture are the scenario proposed by this study, while the hillside remains a constraint

Provision of land resources for the sustainable sengon raw material industry in Bedadung Jember Watershed
Get PDFSengon (Paraserianthes falcataria) menjadi komoditas andalan sebagai bahan baku industri, sehingga sengon memiliki nilai ekonomis yang tinggi. Efek domino yang timbul adalah meningkatnya luasan lahan sengon, dan menyebabkan perubahan tataguna lahan ladang/sawah menjadi perkebunan sengon. Perubahan lahan tersebut rawan erosi yang akan memperbesar tingkat bahaya erosi. Peruntukan lahan yang tidak sesuai untuk komoditas tanaman sengon akan menjadi ancaman tersendiri bagi keberlanjutan agroindustry berbahan baku sengon oleh karena itu diperlukan evaluasi kesesuaian lahan tanaman sengon. Penelitian ini bertujuan mengidentfiikasi kesesuaian lahan tanaman sengon di DAS Bedadung. Infomasi ini digunakan untuk mengembangkan agroindustri yang berkelanjutan. Parameter yang dianalisis sebanyak 14 dan metode kesesuaian lahan adalah matching dan overlay. Hasil dari analisis kesesuaian lahan pada tanaman sengon didominasi kelas S3 “sesuai marjinal” (48,07%). Parameter pada lahan yang menjadi faktor pembatas tanaman sengon adalah curah hujan sebagai penyedia sumber air dan solum tanah. Upaya perbaikan faktor curah hujan yaitu membuat waduk atau bendungan, namun perbaikan tersebut membutuhkan dana banyak dan waktu yang lama. Sedangkan usaha perbaikan solum tanah sulit dilakukan karena membutuhkan waktu yang lama. Dengan demikian maka komoditas sengon di Kabupaten Jember akan mengalami kendala keberlanjutan apabila faktor-faktor diatas tidak dicari solusinya.Sengon (Paraserianthes falcataria) is a mainstay commodity as an industrial raw material, so it has high economic value. The domino effect that appears is the increase in the area of sengon land and causes changes in land use. Land conversion will be vulnerable to erosion and increase the level of erosion hazards. Inappropriate land changes will also threaten the sustainability of the agroindustry, therefore it is necessary to evaluate the suitability of the sengon plant land. This study aims to identify the suitability of sengon land in the Bedadung watershed for sustainable agro-industry development. The analyzed parameters are 14 and the method used is matching and overlay. The results of land suitability analysis on dominant sengon plants were categorized as S3 "marginally appropriate" (48.07%). The limiting factor for sengon plants is rainfall as a source of water and soil solum. Efforts to increase the rainfall factor are to build reservoirs or dams, but these improvements require a lot of money and time. Meanwhile, efforts to improve soil solum are difficult because it takes a long time. Thus, the sengon commodity in Jember Regency will experience sustainability problems if the limiting factor is not found a solution
