Abstract

Fermented cabbage extract contains lactic acid bacteria Lactobacillus plantarum which produces tannase enzymes and Lactobacillus casei which produces phytase enzymes, which are very effective in reducing antinutrient compounds and increasing the antioxidant compound foxtail millet flour. This study aimed to determine the optimal fermentation time (0, 12, 24, 36, and 48 hours) to decrease antinutrient compounds and increase antioxidant compounds of foxtail millet flour using fermented cabbage extract. The results showed that an increase in fermentation time from 0 to 48 hours reduced levels of tannins and phytic acid in foxtail millet flour by 68.64 % (2.71 - 0.85 mg/g) and 66.60 % (5.33 - 1.78 mg/g) respectively. Afterwards there is an increase in antioxidant activity by 83.10 % (42.25 - 77.26 %) and a decrease in total phenolic content by 18.22 % (7.41 - 6, 06 mg GAE/g). In conclusion, the optimal fermentation time to produce FMF with the best characteristics (low antinutrients and high antioxidant activity) is 48 hours. Keywords:   phytic acid, tannin, antioxidant activity, foxtail millet flour, fermented cabbage extract

Abstract

One of the things that are important to consider when fertilizing is how to place the fertilizer so that plants can consume nutrients efficiently. The research objective was to assess the precision of soil conservation based on fertilizer placement so that fertilizers could increase the production of taro effectively. This study applied four treatments, namely without fertilizer, placing manure in the planting hole, placing manure in the biopore, and placing manure on the borders. The three treatments were given 1 kg of goat manure. The treatment was performed with six replications. Harvesting is carried out in 8 months after planting. The results showed that the placement of manure on the borders was the most effective treatment with the highest yield of wet tubers of 21.4 Mg/ha and was not different from the treatment of manure in biopore 18.3 Mg/ha.This yield was different significantly as compared to that of resulted from treatments where fertilizer was placed in the planting hole (15.9 Mg/ha) or the production of taro without manure application (11.57 Mg/ha). Keywords: Organic fertilizers, production, soil conservation, taro

Abstract

The calculation of crop productivity has now been facilitated by technological development using remote sensing technology or data generated by satellites. Determining the value of productivity using images will shorten the time and does not require much effort. A remote sensing model that connects satellite image reflectance data with rice plant parameters will be handy for monitoring biomass growth and predicting crop yields more quickly and efficiently. This study aimed to determine the regression equation to estimate the productivity of regional rice in Harau District, Lima Puluh Kota Regency. This study consisted of several stages: data collection, data processing, and calculation of rice productivity, NDVI regression analysis with rice productivity, and Nash-Sutcliffe Efficiency (NSE) test against the obtained equations. The regression equation obtained from the results of data analysis to estimate rice productivity in Harau District, Lima Puluh Kota Regency is y = - 82152x4 + 208465x3 - 197654x2 + 82986x - 13014, with an NSE value of 0.64 which is categorized as ‘sufficient’.Keywords: MODIS, NDVI, Rice, Remote sensing; Productivity

Abstract

The Internet of Things (IoT) is currently influencing many facets of human life. Smart agriculture is one system that can use the IoT to improve production efficiency and consistency across agriculture, improve crop quality, and reduce negative environmental impacts. The architecture of an IoT-based microclimate monitoring system tailored for use with the Unpad ALG greenhouse is shown in this paper. The suggested system design can collect microclimate data using the SHT11 and GUVA-S12SD microclimate sensors and store it in a database on a Raspberry Pi with a cloud computing back-end idea. The Raspberry Pi is also used to process and analyze data in order to set up mist-based greenhouse cooling systems. The collected data is delivered to a web-based front-end node, where users can access from their own device. The results reveal that when the temperature rises beyond the predetermined threshold of 30°C or the humidity falls below 80%, the system can activate the mist-based cooling system. With a temperature difference of 6.25 degrees Celsius lower and humidity of 28.06 percent greater, the system is able to perform better than it was introduced before. The automation system's performance can reach 15.22% better, however it declines as the light intensity rises.Keywords: Greenhouse, Internet of things, Micro-climate, Misting system, Raspberry pi
