Abstract

Vertisol is a soil that has neutral to slightly alkaline pH. Zinc availability decreases with increasing pH. The existence of symptoms micronutrients scarcity, especially zinc, also caused by the use of highly yielding seeds with unbalanced fertilization. In addition, Zn uptake by plants is sustainability process which resulted in a decrease in nutrient levels of Zn in the root zone. The aim of the research was to determine the optimum Zn formula that can be added to the NPK compound fertilizer and to determine the effectiveness of the fertilizer on the growth and yield of rice. The experiment was arranged by completely randomized block design with 10 treatments and 3 replicates of each treatment. NPK compound fertilizer dose was given 300kg / ha. The result of this study showed that the compound fertilizer NPK + Zn had no effect on plant height, number of tillers and weight of the plant. The additional dose compound of 2% Zn to the dose of compound fertilizer NPK + Zn did not increase the yield. There was a tendency NPK treatment +0.75% Zn deliver the highest results. NPK compound fertilizer application + Zn significantly increased the uptake of Zn.

Abstract

The pandemic situation experienced by the world are currently threatening food security in various regions including Indonesia. In these regions, the flow of traffic in the agricultural and fisheries sectors, from the means of production to the distribution of the harvest, is choked up due to social restrictions in various parts of the region. As a strategic step to reduce the impact on the agricultural sector, it is necessary to accelerate information to support the stability of production and also to distribute production results. Digital media in agriculture are needed to provide education with a variety of contents, such as technical production, marketing, and agricultural finance information. The Faculty of Agriculture of Universitas Gadjah Mada (UGM) has supported digital information dissemination through the Desa Apps application. Desa Apps aims to be an application platform that provides agricultural extension and develops digital farmer communities. The information that has been carried out by Desa Apps so far includes agrocomplex sector (agriculture, animal husbandry and fisheries) problems related to cultivation methods and obstacles faced in the land such as attack by plant pest and disease. As a digital media, the Desa Apps has educated farmer and aquaculturists. Optimization needs to be done to improve the performance of Desa Apps as a digital media, one of which is the marketing system that this application actually has. This study evaluates whether farmers and aquaculturists under the auspices of the Faculty of Agriculture are interested in being able to get education and at the same time be able to market their product directly to consumers with one application, the Desa Apps. The findings of the study showed that the pandemic period greatly affected the incomes of the assisted target community, and they required media that can help market their product. The decline in turnover due to pandemic conditions reached 70% with an average decrease of 39.2%. The method of selling products has changed from conventional to online sales by 20% of the total respondents. Changes in sales methods occurred due to distribution limitations due to regional and activity restrictions during the pandemic. Therefore, it is necessary to optimize the Desa Apps application as a digital media to support food security.
