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

Abstract

Water shortage problem was often happened in many places in Indonesia. Water availability is very important not only for domestic needs, but also for other activities particularly for agricultural activities. To solve water shortage problem, this study aimed to design a water source alternative. The rain is a free water source and collecting rain in the small dam or reservoir is one of the effective rainwater harvesting technique that can increase water availability. This research was conducted  at Sekaran Village and the analysis had done using SWAT (Soil and Water Assessment Tools) model.  The planned rainfall and discharge were analysed by 5 years return period to calculate the water  potential for reservoir charging. The results of this study indicated that the location of the reservoir was planned in a forest area with a slope of 8-25%, on coordinates 111º38'11.39"E and 7º6'14.22"S and has a storage volume of 13737 m3. The reservoir has 4356 m2 surface area with a depth of 3 m. Based on the SWAT model simulation, the highest average discharge potential occured in February with a discharge of 0.312 m3/s and the lowest average discharge occured in October with a discharge of 0.044 m3/s. The total volume of potential annual water that can fill the reservoir is 61.166 m3/s per year based on a planned rainfall of 115.38 mm and a planned flood discharge of 2.54 m3/s with a return period of 5 years. The reservoir construction required a cost of  IDR 1,200,747,000. Keywords: Cost, Location, Rainwater Harvesting, Reservoir, SWAT

Abstract

Coleus scutellarioides is a leaf ornamental plant that is widely used as an ornamental plant in tourist attractions because it has an interesting leaf color. The purpose of study was to obtain right concentration of paclobutrazol for the brightness of the color of the leaves of the coleus plant in shaded conditions. The method used is a Split Plot Design with two factors, light intensity as the whole plot and paclobutrazol concentration as a split plot. The whole Plot consists of 3 levels, namely I100 (100% sunlight intensity), I75 (75% sunlight intensity) and I50 (50% sunlight intensity) while the split plot consisted of P0 (Without Paclobutrazol), P40 (Paclobutrazol 40 ppm), P80 (paclobutrazol 80 ppm) and P120 (paclobutrazol 120 ppm.  The results showed there were interactions from the treatment of paclobutrazol concentrations at various light intensities. The application of paclobutrazol 0 ppm at a light intensity of 75% and 50% gave the same chlorophyll content results as the 100% light intensity treatment and 0 ppm paclobutrazol concentration.The conclusions in addition of paclobutrazol 40-80 ppm at a decrease in light intensity of 75% and 50% gives the result of anthocyanin content and leaf color equal to 100% intensity and paclobutrazol 0 ppm.keyword: Coleus, Shades, Color, Paclobutrazol, Konsentrastion
