Abstract

The problem currently faced by Indonesian coffee in the international market is the low quality of coffee generally produced by community plantations. The quality of coffee is still low because post-harvest processing still produces random coffee, namely coffee beans produced with very simple methods and facilities, relatively high water content and still mixed with other ingredients in relatively large quantities. To improve the quality of coffee beans, the application of Good Agricultural Practices (GAP) was chosen as a framework for analyzing coffee quality, because GAP plays a crucial role in ensuring sustainable and quality agricultural practices. This study aims to determine the extent to which GAP is applied to Arabica coffee cultivation in Simalungun Regency and to find out that the application of GAP can improve coffee quality in accordance with the Indonesian Coffee SNI. The research method used is a descriptive method. The basis for selecting the research location was determined intentionally (purposive method) in Simalungun Regency. The sample in this study was coffee farmers totaling 75 respondents. Data analysis was carried out descriptively and multiple linear regression tests. From the results of the study, it can be concluded that coffee farmers in Simalungun Regency have applied GAP in cultivating coffee plants, where the highest GAP application is found in plant varieties with a score of 4.04 and planting coffee at an altitude that is in accordance with a score of 4, while the lowest GAP application is found in harvesting techniques with a score of 3.55, where there are still many farmers who harvest without considering factors that can affect the quality of the coffee beans produced. The water content of coffee beans in Simalungun Regency is around 11.27%. This is in accordance with the SNI 01-2907-2008 standard, namely a maximum water content of 12.5%. The defect value of koi beans in Simalungun Regency is predominantly quality 2, which is 56% and quality 1 is 33.33%. Coffee beans with quality 1 and 2 have good quality. The size of coffee beans in Simalungun Regency is predominantly medium, which is 69.33% and large size is 26.67%. Partially, the application of Good Agricultural Practices, namely plant varieties, coffee land suitability, altitude, fertilization, pest and disease control have a significant effect on the quality of coffee beans, while harvesting techniques do not have a significant effect on the quality of coffee beans. Simultaneously, the application of Good Agricultural Practices (plant varieties, coffee land suitability, altitude, fertilization, pest and disease control and harvesting techniques have a significant effect on the quality of coffee beans.

Abstract

This research aims to determine the effect of giving Biohayati fertilizer, giving Rhizobium bacteria and also the interaction of giving Biohayati fertilizer on soybean production. This research was carried out in Laut Tador Village, Batu Bara Regency, North Sumatra Province. At an altitude of ± 12 meters above sea level with flat topography. This research used a factorial RAK (randomized group design) with 2 treatment factors. The first factor is the provision of Bio-Biological Fertilizer, which consists of four levels, namely: B0 = No treatment, B1 = Bio-biotic solution with a dose of 18 ml/liter of water, B2 = Bio-biological solution with a dose of 20 ml/liter of water, B3 = Bio-biological solution with a dose of 22 ml/liter of water. The second factor is that the administration of Rhizobium bacteria is carried out at three levels, namely: R0 = no treatment, R1 = Rhizobium at a dose of 1.6 kg/plot (seeds mixed with Rhizobium solution), R2 = Rhizobium at a dose of 1.8 kg/plot (Rhizobium is watered in land). The results of the research show that the effect of providing Biohayati has a significant effect on soybean plant production, namely the number of pods and filled pods. The effect of giving Rhizobium bacteria has a significant effect on soybean plant production, namely the number of pods and filled pods. The interaction effect of giving Biohayati and Rhizobium bacteria on soybean production did not have a significant effect. Providing a biological solution at a dose of 22 ml/liter of water and Rhizobium at a dose of 1.6 kg/production plot to soybean plants is the best dose.

Abstract

This research was carried out in Laut Tador Village, Sei Suka District, Batu Bara Regency, North Sumatra Province. This place is at an altitude of ±25 meters above sea level (masl), with flat topography. This research was carried out from November 2021 to February 2022. This research aims to determine the dose of inorganic fertilizer and types of manure on N, P and K nutrient uptake and on the growth of soybean plants (Glycine max). This research began in October 2021 to February 2022. Factorial pattern research with a factorial Randomized Block Design/RAK. Treatment factors use various types of manure (O) as the first factor and the second factor is the application of inorganic fertilizer (A). The results of soil analysis on the experimental land are generally low, indicated by the organic matter content at the location, namely 0.25%, not reaching 3% according to ideal soil conditions. . Research Results: The type of manure treatment had a significant effect on the number of primary branches, plant height, stem diameter, crown dry weight, number of root nodules, root nodule weight, while the interaction of organic and anoragnic fertilizers had no significant effect on the number of primary branches, plant height and nutrient uptake. . Providing chicken manure at a dose of 15 tons ha produced the highest number of primary branches, plant height, stem diameter, crown dry weight, number of root nodules, and root nodule weight.
