Abstract

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.

Abstract

Durian (Durio zibethinus) is known as a plant that has a fairly high economic value which is widely planted on community land in Pangkatan District, Lauhanbatu Regency, North Sumatra Province. This study aims to evaluate the land suitability class for durian as an agroforestry plant in Pangkatan, Labuhanbatu Regency. Research activities include several stages of activities, namely: preparation, survey, soil analysis in the laboratory, data processing, and mapping. The survey method was carried out to collect soil samples in the field. Durian land suitability class was analyzed using the matching method. The method refers to the references and criteria adopted from the Soil Suitability of Agricultural Crops by the Center for Soil and Agroclimate Research, Bogor, Indonesia. The results showed that the actual land suitability class for durian plants in Sitellu Tali Urang Julu sub-district was marginally suitable (S3) on Land Units 1 and 6 and not suitable (N) on Land Units 2, 3, 4, and 5 with limiting factors. are temperature and soil texture. The results of the GIS analysis show that 52.5% of the total sub-district area is marginally suitable (S3) and 47.8% of the total sub-district area is not suitable (N).
