By 2016, there were 32.70 million ha of degraded forests in Indonesia. If it is not quickly rehabilitated, there will be land use changes and expansion of industrial forest plantation, which significantly affects its biodiversity and environmental. This research aims to study the impacts of the gap planting technique with red jabon on soil density and erosion. The research used: (1) the gap planting technique of red jabon with a proportion of the total gap area to the total natural forest area of 40%: 60%, planting distance of 4m x 5m, and the number of trees planted of 200 stems/ha, (2) Digital-Humboldt Static Cone Penetrometer to measure soil density, and (3) stick for soil erosion measurement. The results showed that gap planting with red jabon to rehabilitate degraded natural forests increased the soil density, but its value was categorized as a very loose soil class. On the other hand, the soil erosion in gap area was lower than in degraded natural forest area, because the condition of a part of the degraded forest was unvegetated land, and there were the wastes of branches, twigs, and leaves as well as grown grasses on the soil surface that hinder the soil erosion in the gap area. This research concluded, that the impact of the gap planting on soil density can be neglected, and the impact of the gap planting on soil erosion is positive. Further research on social-economic, biodiversity, effective and efficiency aspects of the gap planting technique for forest rehabilitation are needed before its implementation.

“…Terdapat beberapa faktor penyebab erosi yang dapat dikelola yaitu jenis penutupan lahan dan pengolahan lahan. Pengendalian alih fungsi lahan harus dilakukan karena beberapa hasil penelitian menunjukkan bahwa perubahan penggunaan/penutupan lahan menjadi salah satu penyebab terjadinya erosi (Ozsahin et al, 2018;Rhoades et al, 2011;Sharma et al, 2011). Pembukaan lahan hutan untuk lahan pertanian harus dikendalikan.…”

Degradasi lahan di DAS Brantas terjadi sangat masif yang tercermin dari tingginya erosi dan sedimentasi. Nilai erosi penting untuk diketahui sebagai salah satu informasi dasar tentang degradasi lahan dalam suatu DAS. Tujuan penelitian ini adalah untuk menganalisis dan mengidentifikasi sebaran lahan terdegradasi di DAS Brantas sebagai upaya untuk penanggulangan degradasi lahan melalui rehabilitasi hutan dan lahan secara tepat sasaran. Analisis erosi dilakukan secara spasial dalam skala DAS menggunakan metode Universal Soil Lost Equation (USLE). Hasil analisis menunjukkan bahwa nilai erosi tertimbang di DAS Brantas sebesar 448,73 ton/ha/tahun yang termasuk dalam klasifikasi tingkat erosi tinggi. Wilayah DAS Brantas seluas 408.818 ha (41,74%) merupakan lahan yang perlu penanganan erosi karena 22,51% termasuk dalam kategori nilai erosi tinggi dan 19,23% termasuk dalam nilai erosi sangat tinggi. Lahan-lahan tersebut teridentifikasi mempunyai penutupan lahan dengan fungsi hutan lindung, hutan produksi, tegal, dan kebun campuran. Jenis tanah dan erodibilitas menjadi sebagian penentu tingginya nilai erosi, namun demikian merupakan faktor yang sulit untuk dikelola. Jenis penutupan lahan dan pengolahan lahan menjadi faktor penyebab erosi yang mudah dikelola. Pendekatan rehabilitasi hutan dan lahan dapat digunakan sebagai salah satu upaya pencegahan dan penurunan erosi dengan memperhatikan pemilihan jenis yang terkait habitus (bentuk dan stratifikasi) dan nilai ekonomi Kata Kunci: DAS Brantas, degradasi lahan, rehabilitasi hutan dan lahan Equation) method. Analyses showed that weighted soil erosion values in the Brantas river basin were 448.73 tons/ha/year which was classified as high erosion level. The area of 408,818 ha (41.74%) of Brantas river basin needs erosion handling because 22.51% was identified in the high erosion value category and 19.23% was included in very high erosion values. Those areas were identified as protected forests, production forests, dry land, and mixed gardens. The type of soil and the erodible of soil are part of the determinants of the high value of erosion, but these factors are difficult to manage while land cover types and land management which are the causes of erosion are relatively manageable. The approach to rehabilitate forests and land can be used as an effort to prevent and reduce erosion by taking into account the selection of related types of habitus (form and stratification) and economic value. Keywords: Brantas river basin, land degradation, forests and land rehabilitation ABSTRACT Land degradation in the Brantas River Basin occurs very massively as reflected by high erosion and sedimentation. Information related to soil erosion is important since it is one of the basic information in determining the degraded land in a watershed. The purpose of this study was to analyze and identify the distribution of degraded land in the Brantas river basin as an effort to mitigate land degradation through forests and land rehabilitation in suitable locations. Erosion analysis was carried out sp...

“…A large number of previous studies show that intensive rainfalls [5][6][7][8][9][10], topography [11][12][13][14][15][16], vegetation type [17][18][19][20], land use [21][22][23][24][25], and land management [26][27][28][29][30][31] are the main factors that determinate the rates of soil erosion. The studies of natural conditions in the South Morava River Basin (Grdelica Gorge) uniformly show that this area is predisposed to intensive soil erosion [2,32].…”

Abstract:The aim of this research was to analyse the changes in the soil erosion intensity caused by erosion control works (ECW) in Grdelica Gorge (The South Morava River) in the period between 1953 and 2016. For the purpose of quantifying the erosion intensity changes, the erosion potential model (EPM) was used to calculate the annual gross erosion (W), sediment transport (G), and erosion coefficient (Z) in the study area. As a result of the performed technical and biotechnical erosion control works, there was a general decreasing trend in the intensity of soil erosion processes in the last 63 years. The specific annual gross erosion in Grdelica Gorge was 1920.34 m 3 /km −2 /year −1 in 1953, while in 2016 it was 492.42 m 3 /km −2 /year −1 . The specific sediment transport was 1421.05 m 3 /km −2 /year −1 in 1953 and 364.39 m 3 /km −2 /year −1 in 2016. Due to the changes in the intensity of erosion processes, the specific annual gross erosion in the study area decreased by 1427.92 m 3 /km −2 /year −1 and the specific sediment transport by 1056.66 m 3 /km −2 /year −1 . The value of the erosion coefficient was reduced from Z = 0.84 in 1953 to Z = 0.32 in 2016. The results show that there is a significant correlation between the soil erosion intensity (erosion coefficient) and ECW (biotechnical works) performed in Grdelica Gorge. The permanent control of erosion processes in Grdelica Gorge is very important for torrential flood prevention and protection of two very important traffic routes (Belgrade-Skopje-Athens railway and motorway-Corridor X), as well as settlements, local roads, and other facilities in this area. Furthermore, these results are the basis for future water management projects, soil and environmental protection, spatial planning, agriculture, and other human activities.
