    Abstract
    The Agroecology Character Study of Padangsidimpuan Salak Plantation Based on Productive Potency in South Tapanuli. Supervised by Abdul Rauf and Lollie Agustina P. Putri. The objektive of this research was to know the relation of each agroecology characteristic toward productive potency, the relation of all toward productive potency and the most dominant agroecology characteristic in producing level. This research was done in four subdistricts, Angkola Barat, Angkola Selatan, Marancar and Batang Angkola in South Tapanuli Regency, started from April through August 2012. This research was done by a field survey methode based on productive potential parameters which is divided into three parts, namely : a high productive potency ( 10000 ≤ x kgs/hectare/year), a middle productive potency ( 6000 ≤ x < 10000 kgs/hectar/year), a low productive potency (3000 ≤ x < 6000 kgs/hectare/year). An observation was done to organic C ( %), soil nutrient nitrogen (%), soil nutrient phosphorus (ppm), potassium soil nutrient (%), soil nutrient magnesium (%), The depth of effective solum (m), leaf nitrogen nutrient (%), leaf nutrient potassium (%), leaf nutrient phosphorus (%), the inclination of soil (%), the height of soil (m), the temperature of air (0C), the temperature of soil (0C). To know the correation between agroecology characteristic toward productive potency, an analysis of regression and correlation was applied. The result of this research showed that nitrogen, kalium, pH, leaf nitrogen, as wells leaf fosfor are agroecology characteristic which influenced productive potency level by 84.4 % determined coeffcient. To know the most dominant agroecology characteristc, a stepwise methode was applied. . The result showed that the status of calium and fosfor of content soil, status nitrogen content leaf, the environment factor of soil temperature influenced productive potensy.
     
    Kajian Karakteristik Agroekologi Tanaman Salak Berdasarkan Potensi Produksi di Kabupaten Tapanuli Selatan. Dibawah bimbingan ABDUL RAUF dan LOLLIE AGUSTINA P. PUTRI. Tujuan penelitian ini adalah untuk mengetahui hubungan masing-masing karakteristik agroekologi dengan potensi produksi, hubungan semua karakteristik agroekologi terhadap potensi produksi, dan karakteristik agroekologi yang paling dominan dalam menentukan produksi. Lokasi penelitian dilakukan diempat kecamatan yaitu Angkola Barat, Angkola Selatan, Marancar, dan Batang Angkola di Kabupaten Tapanuli Selatan, yaitu pada Bulan April sampai Agustus 2012. Penelitian ini dilakukan dengan metode survey lapang berdasarkan parameter yang dipergunakan yaitu potensi produksi yang dibagi atas tiga kategori, Potensi Produksi Tinggi (10000≤ x kg/ha/tahun), Potensi Produksi Sedang (6000 ≤ x < 10000 kg/ha/tahun), Potensi Produksi Rendah (3000 ≤ x < 6000 kg/ha/tahun). Pengamatan dilakukan terhadap C-Organik (%), unsur N (%), unsur P (ppm), unsur K (%), unsur Mg, kedalaman solum efektif (m) , unsur N daun (%), unsur P daun (%), Unsur K daun (%), kemiringan lahan (%), ketinggian tempat (m), suhu udara (0C), suhu tanah (0C). Untuk mengetahui hubungan karakteristik agroekologi dengan potensi produksi dilakukan analisis regresi dan korelasi. Hasil penelitian menunjukkan bahwa nitrogen, kalium, pH, nitrogen daun serta fosfor daun merupakan karakteristik agroekologi yang mempengaruhi tingkat potensi produksi dengan koefisien determinasi 84,4 %. Untuk mengetahui karakteristik agroekologi yang paling dominan dilakukan uji dengan metode stepwise. Hasil penelitian menunjukkan bahwa status hara tanah kalium dan fosfor, status hara daun nitrogen, dan faktor lingkungan suhu tanah merupakan faktor yang paling dominan mempengaruhi potensi produksi.
