Abstract

Sub-optimal land is land that has low productivity due to parent material, physical, chemical, biological properties of the soil, rainfall, and extreme temperatures. To meet the availability of national food sources, it is necessary to utilize sub-optimal land that is widespread in mainland Indonesia. The purpose of the study was to determine recommendations for increasing sub-optimal land potential based on land suitability classes for several food crops, namely lowland rice, upland rice, cassava, sweet potato, corn, soybean, and peanut. The research was conducted in Stabat District, Langkat Regency from June to November 2020, and the Asian Agri Laboratory of North Sumatera Province. The research method used is the survey method, while to determine the suitability of the land, namely the matching method. Land potential in Stabat District can be increased by managing it in the form of recommendations for adding N fertilizer was 7,000 kg N/ha or the equivalent of 1,555 kg urea/ ha, the addition of P fertilizer was 158.8 Kg P2O5 or equivalent to 441 Kg SP36/ha, K fertilizer was 26.32 Kg K2O/ha or the equivalent of 43.86 Kg KCl. The adding organic matter or compost is 43.8 kg C-organic/ha or equivalent to 63.9 kg compost/ha.

Abstract

Salinity is one of the problems in agricultural land in the world, including in Indonesia. Vetiver is quite tolerant of planting in saline soils at a certain level of salinity, but vetiver growth is inhibited at high salinity levels. The purpose of this study was to evaluate the effect of gibberellin in saline soils on the growth and production of vetiver (Vetiveria Zizanioides L.). This research was conducted in the greenhouse of the Faculty of Agriculture, Universitas Sumatra Utara, Medan. This study used a non-factorial completely randomized design, It was salinity stress (S) which consisted of 3 factors: Gibberellin concentrations of 0 (without treatment), 50 ppm, and 100 ppm. The results of this study indicate that giving Gibberellins in salinity stress conditions has a significant effect on the observed variables of plant height, specific leaf area, and cuticle thickness.

Abstract

Vetiver (Vetiveria zizanioides L.) plants are able to protect the soil from erosion and are tolerant of salinity stress. However, at high salinity levels, vetiver plants show a decreasing growth. The application of gibberelin is expected to increase the growth of vetiver in salinity stress conditions. The purpose of this study was to evaluate the growth responsiveness and production of vetiver the application of gibberelin under salinity stress conditions. This research was conducted in the green house of the Faculty of Agiculture, Universitas Sumatera Utara, Medan. This study used a non-factorial completely randomized design, namely the salinity stress (S) which consisted of 3 levels, each treatment was repeated 3 times, so that 9 treatment combinations were obtained: the concentration of gibberelin was 0 (no treatment), 50 ppm and 100 ppm.

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

This research aims to analyze the application of Good Agriculture Practices (GAP) to nutrient absorption in the leaves of Arabica coffee plants (Coffea arabica L.) in North Sumatra Province. Data analysis method is quantitative method. The data analysis technique used in this research is descriptive analysis technique to describe the data that has been collected through field surveys which include field observations, leaf sampling and laboratory analysis results to measure nutrient content. The results showed that the application of GAP, including good soil management, planned fertilization significantly increased nutrient uptake in the leaves. The GAP managed crops showed increased levels of phosphorus compared to those managed conventionally. The application of GAP therefore not only improves soil chemical characteristics, but also increases coffee plant productivity through optimizing nutrient uptake, which can contribute to the sustainability of coffee plantations in North Sumatra. Keywords: GAP, leaf nutrient absorption, arabica coffee, north sumatra

Abstract

In Indonesia, the economy is one of the obstacles to sustainability in the education sector. thus forming a scholarship program. In determining scholarship recipients, a selection is carried out where there are several predetermined criteria. To get the best criteria in determining scholarship recipients, it can be done by using a Decision Support System with the Analytical Hierarchy Process method where the main input is human perception. The criteria used in this study were GPA, parents' income, number of family dependents, active students, and KTP which were very influential in determining scholarships. Each criterion will be given a level of importance, which can be done by comparing one criterion with another. The problem faced is that conventional data collection processes often occur errors. The purpose of the research is to prevent errors in data collection, and the process for results for scholarship recipients is more optimal. This research was conducted at PGRI University, West Sumatra in February 2023. This web-based Decision Support System was designed using the PHP programming language and MySQL database with XAMPP as the local server. The results of this study indicate that the criteria used greatly influence the determination of scholarship acceptance.
