Land degradation is one of the causes of lack of success of agricultural activities in Indonesia because of a decline in land productivity continuously and ultimately reduce the level of income / welfare of farmers. Land degradation can occur either on dry land or in wetlands, so prevention and / or rehabilitation of degraded land is very important that the agricultural area can be used on an ongoing basis. Land degradation is the loss or reduction of utility or potential use of land, loss of or changes in land features that are not hindered replaced. According to FAO (1993), soil degradation is a process that describes the phenomenon which lower the capacity of soil to support life. Land degradation is a process of decline of soil productivity, temporary or permanent, so that eventually the land can lead to a certain critical level (Dent, 1993). The process includes various forms of land degradation levels.

Kecamatan Ciater termasuk wilayah Kabupaten Subang bagian selatan yang memiliki fungsi strategis sebagai kawasan resapan air, yang didalamnya melingkupi cagar alam, taman wisata alam serta sebagian wilayahnya merupakan hutan produksi. Kondisi ini perlu dikendalikan pemanfaatannya secara tepat dan berkelanjutan. Pemanfaatan sumberdaya alam untuk kepentingan ekonomi terkadang mengabaikan faktor lingkungan. Oleh karena itu, perlu adanya keselarasan antara penggunaan lahan, kebijakan (pola ruang), dan daya dukung lahannya (kemampuan lahan), agar tidak terjadi kerusakan/bencana. Penelitian ini bertujuan mengetahui jenis-jenis tutupan/penggunaan lahan tahun 2006 dan 2019 serta perubahannya, mengevaluasi keselarasan penggunaan lahan 2019 dengan pola ruang RTRW Kabupaten Subang 2011-2031 dan daya dukung lahannya serta informasi zona nilai tanah pada setiap kombinasi keselarasan. Metode dasar yang digunakan antara lain sistem informasi geografi (deliniasi visual, overlay, query), dan matriks logis keselarasan serta analisis kemampuan lahan dengan pengumpulan data dari pengamatan lapang, Hasil penelitian menunjukkan tutupan/penggunaan lahan terluas di masing-masing tahun adalah hutan sekunder kerapatan sedang dengan persentase 22.72% pada tahun 2006 dan 18.85% pada tahun 2019. Perubahan penggunaan lahan yang paling luas adalah dari hutan sekunder kerapatan sedang pada tahun 2006 berubah menjadi kebun campuran pada tahun 2019 dengan persentase luas 25.25% (173.35 ha). Kelas kemampuan lahan II, III dan IV di Kecamatan Ciater persentase cakupan luasnya 79.89%, sedangkan kelas kemampuan lahan VI seluas 20.11%. Hasil analisis menunjukkan persentase keselarasan 57.25% selaras, 20.44% tidak selaras, dan 22.30% transisi. Dengan demikian, lahan di wilayah studi relatif masih baik dalam hal keselarasan antara daya dukung lahannya dengan kebijakan yang ada. Namun demikian, adanya bencana pada titik-titik lokasi tertentu perlu mendapatkan perhatian bagi seluruh pihak untuk dilakukan mitigasi. Hasil lainnya, menunjukkan keselarasan lahan tidak dipengaruhi oleh nilai tanah, karena terlihat pada lahan yang selaras (S) maupun tidak selaras (TS) sama-sama pada nilai lahan yang rendah. Dalam perencanaan lahan, aspek ekologi dan ekonomi merupakan aspek penting yang perlu diperhatikan.

Abstract: High production of rubber plants in Rokan Hulu district has not significantly contributed yet to increasing the welfare of rubber farmers. This is due to a lack of rubber processing industry, leading to rubber being sold in the form of primary product (fresh sap). Therefore, developing an agro-rubber industry is of capital importance. The purposes of the present study were (1) analyze the marketing margin of rubber gum at each marketing level in Rokan Hulu district; (2) analyze the role of rubber agro-industries in the economics of Kampar and Rokan Hulu regions; (3) develop rubber agro-industry to improve the economics of Rokan Hulu district. The methods used in the present research included analysis of marketing margins, input and output analyses, and AHP (Analytical Hierarchy Process). The results showed that both crumb and smoked rubbers sectors play strategic roles in developing other sectors in Kampar district (DFL, IFL> 1). In addition, it was also observed that the rubber sector tended to use the output of other sectors as production inputs (DBL, IBL> 1). Both crumb and smoked rubbers sectors had great abilities to influence not only the regional output multiplier (multiplier output), but also the income multiplier (income multiplier) (I > 1). However, the ability of the NTB multiplier (multiplier NTB) to improve the sectors was very low (NBT <1). This showed that rubber industry has better development opportunities in Rokan Hulu. The type of rubber processing industry to be developed in Rokan Hulu depends on the perceptions of stakeholders. For instance, a rubber industry that can produce products such as rubber crumb, sheet, Sir 10, and Sir 20. Initial attempts by local government in developing the rubber industry is the increase of qualified, skilled, and reliable human resources to insure optimal functioning of the rubber agro-industry.
