Agricultural cultivation activities that do not apply conservation methods on steep slopes are expected to increase the rate of erosion in this region. This study is aim to determine the magnitude of potential erosion and erosion hazard index in Sub watershed Pasui upstream Saddang watershed. The method of study is conducted survey and soil sampling in Sub watershed Pasui, Baraka subdistrict and Buntu Batu, Enrekang regency. The study took place from February to August 2021. Erosion restoration uses the USLE method, while the restoration of erosion hazard index refers to The Minister of Forestry Regulation No. 60 of 2014. Paddy field cover, mixed dry land agriculture and forest are classified as low erosion hazard index class with potential erosion value <15 ton/ha/year. Meanwhile, dry land and savanna agriculture belong to a very high erosion hazard index class with a potential erosion value. The weighted average potential erosion value is 189,46 tons/ha/year, while the weighted average erosion hazard index in the Sub watershed Pasui upstream Saddang watershed is 8,83 and belongs to the highest erosion hazard class.

Aktivitas budidaya pertanian yang kurang menerapkan metode konservasi pada lereng yang curam diduga akan meningkatkan laju erosi pada wilayah ini. Tujuan. Penelitian ini bertujuan untuk menentukan besarnya erosi potensial dan indeks bahaya erosi di Sub DAS Pasui hulu DAS Saddang. Metode. dilakukan survei dan pengambilan sampel tanah di Sub DAS Pasui, Kecamatan Baraka dan Buntu Batu, Kabupaten Enrekang. Penelitian ini berlangsung pada bulan Februari sampai Agustus 2021. Pendugaan erosi menggunakan metode USLE, sedangkan pendugaan indeks bahaya erosi mengacu pada Peraturan Menteri Kehutanan No. 60 Tahun 2014. Hasil. Penutupan lahan sawah, pertanian lahan kering campur dan hutan tergolong kedalam kelas indeks bahaya erosi rendah dengan nilai erosi potensial <15 ton/ha/tahun. Sedangkan, pertanian lahan kering dan savana tergolong kedalam kelas indeks bahaya erosi sangat tinggi dengan nilai erosi potensial >180 ton/ha/tahun. Kesimpulan. Nilai erosi potensial rata-rata tertimbang yakni 189,46 ton/ha/tahun, sedangkan indeks bahaya erosi rata-rata tertimbang di Sub DAS Pasui hulu DAS Saddang yakni 8,83 dan tergolong ke dalam kelas bahaya erosi tinggi.

A model is developed in which the pattern of convergence is attributed to the rate of technological adoption across regions. According this model convergence towards leading regions is feasible only for regions with a sufficient ability to adopt technology. A scheme of measurement is developed to calibrate this argument and data for the EU27 NUTS-2 regions for period 1995-2006 are used to develop an empirical analysis of the processes and conditions that have been hypothesised as generating differential regional economic change. The results suggest that adoption of technology has a significant effect on regional growth patterns in Europe, and hence the analysis has important implications for the direction of regional policy in Europe.
