Abstract

This research activity was carried out on coffee farmer groups in Mandan Sucen Gemawang Temanggung which emphasized the design of automatic sprinklers using microcontroller-based soil moisture sensors for coffee plants. Coffee plants need enough water for their growth. Manually sprinkling coffee plants requires sufficient resources, the problem is that there are human limitations in helping with maintenance and it takes quite a long time. The purpose of this research is to help coffee farmers by designing coffee sprinklers automatically. The research method used to complete this research is Research and Development which includes tool planning, tool design, tool testing, and analysis of an automatic plant watering system using a microcontroller-based soil moisture sensor on YL-69 type coffee plants. The output of the research is a prototype of an automatic plant sprinkler system using sensors, microcontrollers, relays and a 16x2 LCD display screen. From the calibration results, the accuracy of the tool is 97.41% and the error is 2.59%. This system can monitor and control the water requirements of coffee plants and automatic watering is carried out when the soil moisture is < 40%, the pump will start automatically and the pump will automatically turn off when the soil moisture is > 60%. The conclusion from the results of this study is that there is a sprinkler automatically using a microcontroller-based soil moisture sensor to assist coffee farmer groups in Mandan Sucen Gemawang Temanggung in watering coffee.

Abstract

The study objective was to determine the response of growth and production of oil palm on frond fertilizer application. The duration experiment, from June 2017 to April 2018 at the Educational and Experimental Garden of the Stiper Agriculture Institute, Stiper Edu Agro Tourism (SEAT), Ungaran, Central Java, Indonesia. This study used an experimental method with a completely randomized factorial design. The first factor was the age of plants consisting of 2 levels for 6 years old plants and 12 years old plants. The second factor was the dose of frond fertilizer application with 3 levels of application. As control (5 kg/plant/year NPK fertilizer), 2 kg/plant/year frond fertilizer, 4 kg/plant/year frond fertilizer. The experiment using 7 replications for each combination treatment. The result on vegetative growth of oil palm showing the same effect on control and frond fertilizer applications. However, significant increase of production shown in the frond fertilizer application. The total weight of fresh bunches based on harvest observations in January, February, March and April 2018, the highest at the age of 6 years old oil palm which was given 2.0 kg/plant/year frond fertilizer (63.2 kg FFB/4 months). Oil palm productivity with an application of 2.0 kg/plant/year frond fertilizer showing result of 18.96 tons of FFB/ha/year. Compared this to the productivity of control with gain of 6 tons of FFB/ha/year. The highest average weight of fresh bunch in oil palm age 12 years in 4.0 kg frond fertilizer application, with average weight of fresh bunch was 14 kg. Keywords: oil palm, frond fertilizer, vegetative growth, productivity
