Abstract

Coffee is a mainstay plantation commodity in Toba Regency which is managed independently by the community where the land around the Lake Toba area is one of the potential lands in Toba Regency for developing Arabica coffee commodities because geographically Toba Regency is located at an altitude of 900 meters to 2,200 meters above sea level and directly borders Lake Toba. The strong roots of coffee plants make this plant one of the mainstays in preserving forests, restoring critical land, preventing erosion and flooding during the rainy season. The aim of this research is to analyze the land suitability of Arabica coffee plantations in Toba Regency. The method used to analyses the land suitability by using the matching method which was carried out by matching land characteristics with parameters/ criteria for plants based on Land Map Unit (LMU). The research results show that the area of Toba Regency based on the Geographic Information System (GIS) is 207,518.31 ha. Very suitable (S1) land suitability for Arabica Coffee Plants covering an area of 67,844.68 ha (32.69%), an area of 132,030.09 ha (63.62%) has S2 suitability class and an area of 7,643.54 ha (3.68%) has marginal suitability (S3). The potential land suitability class for coffee plants in Toba Regency becomes very suitable (S1) covering an area of 67,844.68 ha or 32.69%, moderate suitable class (S2) with temperature limitation covering an area of 132,030.09 ha (63.62%) and marginal suitability (S3 with temperature limitation) covering an area of 7,643.54 ha or 3.68%. Nutrient deficiencies were corrected by adding phosphorus (P) fertilizer of 4.19 kg P/ha or 9.31 kg SP36/ha or 11.63 kg TSP/ha. Nitrogen (N) fertilizer is 75 kg N/ha or the equivalent of 166,625 Kg Urea/ha. Potassium (K) fertilizer as much as 3 kg KCl/ha. Compost fertilizer is 10.56 tons of compost/ha.

Abstract

Seeds are generally used for moringa cultivation. However, the seeds produced have a fairly hard seed coat, thus affecting germination and seed vigor. The research by immersing seeds with plant growth regulators (PGR) and a comparison of the composition of planting medium need experimentation to get the maximum PGR concentration and the right composition of the planting medium to grow. The study was conducted using a Split Plot Design with the main plots PGR consisting of Z1 (freshwater), Z2 (Coconut liquid), and Z3 (GA3). The subplot is Plant Medium consisting of M1 (soil: sand: manure-1:1:2); M2 (soil: sand: manure-1:2:1); M3 (soil: sand: manure-2:1:1). Data were examined by Analysis of Variance and continued by DMRT at α 5%. The results of the analysis showed that PGR had a significant effect on plant height, stem diameter, and root length. The composition of the planting medium caused significant differences in plant height, stem diameter, number of leaves, and fresh and dry leaf weight. The interaction between the planting medium and PGR caused differences in stem diameter at 2 and 8 weeks after planting. The recommended PGR treatment is freshwater for longer roots and taller plants. M1 planting media produced the most number and weight of leaves. The combination treatment of Z3M2 produces the largest stem diameter.

Abstract

This study aims to examine the level and factors that influence the participation of oil palm planters ( Elaeis guineensis Jacq.) in marketing their products at the Multi-Business Consumer Cooperative in Pematang Bandar District, Simalungun Regency. The research method used is quantitative research with a descriptive approach. The implementation of this study was carried out in Pematang Bandar District, Simalungun Regency, involving 54 respondents. Primary data includes the characteristics of farmers who are members of cooperatives and the results of questionnaires from the independent and dependent variables. The data was processed using multiple linear regression test. The results showed that the level of participation was categorized as very high with a value of 84.1% and the variables of service quality, welfare of extension workers, knowledge of cooperatives, interest in cooperatives and member satisfaction had a significant effect on the participation of smallholders. The variables of the role of the extension worker and the ability of the administrators have no significant effect.

Abstract

Study of Talling Suitability for Palm Oil (Elaeis guineensis Jacq) Production at PT. Langkat Nusantara Kepong Tanjung Beringin Gardens. The purpose of this study was to examine the percentage of suitability of talling with production and to examine the factors that affect the suitability of talling with oil palm production at PT. Langkat Nusantara Kepong Tanjung Beringin Gardens. This assessment was carried out from March to June 2022. The data collection method was carried out by means of interviews with garden assistants and harvest foreman and secondary data was obtained from the division office. The statistical analysis used was a simple statistical analysis using tables and diagrams using a one sample t-test which is used to compare the difference in the percentage of talling with the production to be compared with company standards. The results showed that the talling calculation was not accurate with the realization of production with a percentage of 91.67%. The factors that affect the suitability of talling with the realization of production were the accuracy of talling calculations, rainfall, fruit loss in the field and the number of harvesters with their work performance.
