Penelitian ini bertujuan untuk mengetahui keanekaragaman aksesi aren yang tersebar di Kabupaten Tapanuli Selatan dan mengelompokkan populasi seleksi untuk mendapatkan produksi yang tinggi. Delapan puluh aksesi aren populasi alam asal empat kecamatan telah di identifikasi menurut IPGRI (International Plant Genetic Resources Institute, 1995) dan dianalisis. Hasil menunjukkan terbentuknya 4 cluster yang disimpulkan bahwa cluster 1 merupakan kelompok aksesi aren dengan karakter fenotip yang sesuai untuk memproduksi buah dari mayang bunga betina. Sedangkan cluster 3 merupakan kelompok aksesi aren dengan karakter fenotip yang sesuai untuk memproduksi nira (bahan baku gula aren) dari mayang bunga jantan.

Identification Phenotypic Character of the Leaves Palm Plant in South Tapanuli Regency This studyaims to determine the effect of the phenotype character of palm leaf leaves on the production of roomiein wild populations of natural habitats in South Tapanuli Regency. The study was conducted in fivevillages in each oft he four sub-districts in the South Tapanuli district. Two hundred sugar palm plantsoriginating from four natural habitats have been identified in accordance with plant identificationprocedures issued by the IPGRI (International Plant Genetic Resources Institute, 1995) and analyzed.The results show that 4 clusters were formed with 75% similarity or 25% diversity. These results canbe concluded that cluster 1 is the population of palm plants that have the long character of petioleand the highest number of unproductive leaves. Whereas the characters of leaf length and rachis lengthare still lower than the population of sugar palm plants in cluster 4. Cluster 2 is the population of sugarpalm plants that has the highest character of sap production per day. Cluster 3 is a population ofpalm plants that have the highest leaf width character. Cluster 4 is a population of palm plants thathave the highest leaf length and rachis length with the highest number of leaflets and the largest rachiscircumference and petiole circumference. The number of productive leaves and the percentage of sapsugar content above average.

This study aims to determine and complete the database related to the productivity level of male palm flower stalks in producing sap in wild populations of natural habitats in the South Tapanuli Regency. The research was conducted in 2 villages in 4 districts with a total sample of 40 palm plants. The stages in this research were carried out in three stages. The first stage is a survey sampling carried out by purposive sampling, namely the sampling technique to be used as a sample based on existing criteria, namely: 1. The shape of the stalk, 2. Color of a stalk, 3. Color of series, 4. Color of sap, 5. Length of stalk, 6 7. Stalk Diameter, and 7. Nira Production Data. The second stage is the data collection on the productivity of male palm flower stalks at all levels of the stem in producing sap. The third stage is a productivity data analysis. The results showed that the productivity of male flower stalks at each stalk level was in accordance with the amount of production and weight of sugar produced. Male flower stalk I have the highest amount of sap production and sugar weight followed by stalk levels II, III, IV, and V. Male flower stalk I have the best productivity of all levels of the male flower stalk, after that there is a decrease in the production of sap and sugar for productivity. Male flower stalks II, III, IV, and V. Productivity of the best male flower stalks produced an average sap production of 968.55 liters/stalk and an average sugar weight of 526.79 kg.
