An irrigation control system has been developed and used to estimate evapotranspiration of contamer-grown plants by monitoring randomly selected plants within a container block and watering on an “as needed” basis. Sensor reliability and operational ease allows application of the system in a wide variety of field conditions. First-year tests, using red oak (Quercus rubra L.) seedlings, showed a reduction of 95% or better in both total irrigation and leachate rates with the computer-controlled treatment relative to a manually controlled, drip irrigation treatment without reducing plant growth.

Abstract Effect of irrigation on some growth parameters of cup plant and dehydrogenase activity in soil. A field experiment carried out in two vegetation seasons in the years 2012 and 2013 on very light soil at Kruszyn Krajeński, in the vicinity of Bydgoszcz (Poland). Investigation of the influence of drip irrigation on some growth parameters of three- and four-year-old cup plant (Silphium perfoliatum L.) and on the activity of dehydrogenase participating at cycling in soil was examined. The cup plants were cultivated from the micropropagation seedlings. Experiments were performed as one factorial in four replications. The factor of the experiment was the following variants: O - without irrigation (control plots), D - with drip irrigation. Drip irrigation was scheduled according to tensiometers indications. Irrigation significantly increase the height of the plants, the length of internode, the thickness of the stalk, the fresh weight of the shoots, and the number of the leaves and flowers. Irrigation also increased the transpiration leaf area and the dry matter content. In the soil sampled under cup plant in 2012 there was found a greater activity of dehydrogenases in soil derived from non-irrigated objects.

The authors have researched on the communication protocols and the diagnostic modes used by the second generation of On-Board-Diagnosis (OBD-II) system and put forward a project scheme of automotive fault real-time alarming system based on OBD-II system. The Total Control Unit (TCU) of the alarming system, the signal conversion module between TCU and OBD-II system, the preliminary expert system of automotive fault diagnosis, LCD display system and phonic broadcast system have been developed. Test results on sample machines prove that the alarming system can successfully acquires data stream & trouble codes from automotive electronic control unit, so the expert system can comprehensively analyze potential fault causes and provide the driver with solutions. The fault causes and solutions can be displayed on LCD and converted into voice by text-to-speech module. The wide spread of the alarming system would effectively reduce the costs of vehicle operation and maintenance and greatly improve the vehicle road safety.

This paper is about an automatic irrigation control system which is cost effective and can be used for irrigation by a farmer. Today’s industrial automation and controlling of machine is high in cost and not suitable for a farming field. So, here we design a smart drip irrigation technology with effective control system in low cost. The voltage monitoring unit informs the farmer about the power supply conditions on the field. The aim of this study, is to control the motor automatically, and decide the direction of the water flow through valves, based on the inputs from the farmer and also with the collective inputs from the sensors, which finally notify instantly about the happenings and conditions of the field. It operates under low hardware cost by distributing irrigation to crops by elevation change and gravity. The soil moisture and amount of flow of water in each sector are major consideration to design a fail-safe system for a variety of crops planted at a time.

Abstrak. Pemberian air irigasi secara berlebihan yang tidak sesuai dengan kebutuhan air tanaman akan mempengaruhi pertumbuhan dan produksi tanaman. Salah satu model irigasi yang memungkinkan untuk mengatur jumlah air sesuai dengan kebutuhan tanaman adalah sistem irigasi tetes. Penjadwalan irigasi secara otomatis sangat mendukung disaat cuaca yang susah diprediksi akibat adanya perubahan iklim global. Tujuan penelitian ini adalah untuk menguji kinerja mikrokontroler pada sistem irigasi tetes yang mampu bekerja secara otomatis berdasarkan perubahan kadar air tanah pada tanaman pakcoy. Penelitian  ini dilakukan di desa Lambhuk, Kecamatan Ulee Kareng, Kota Banda Aceh dengan ketinggian lahan 3,8 m di atas permukaan laut dengan ordo tanah regosol. Metode penilitian yang digunakan adalah tahap persiapan yaitu pengambilan sampel tanah untuk dianalisis di laboratorium, pembuatan jaringan sistem irigasi tetes, persemaian benih pakcoy, persiapan media tanam sebanyak 8 pot tanam, pengkalibrasian sensor kelembaban tanah, persiapan bibit pakcoy serta penanaman, dan pemasangan sistem kontrol irigasi tetes otomatis. Tahap pengamatan yaitu diukur tinggi dan jumlah helai daun pakcoy, dan ditimbang bobot segar pakcoy. Hasil penelitian menunjukkan bahwa sistem kontrol irigasi tetes otomatis dapat memenuhi kebutuhan air tanaman pakcoy berdasarkan penentuan kadar air tanah pada keadaan air tersedia, dengan koefisien determinasi (R2) sebesar 0,687. Kinerja alat penyiraman otomatis dengan menggunakan mikrokontroler dapat berfungsi dengan baik dalam memberikan air ke tanaman sesuai dengan yang diinginkan, hal ini dapat dilihat dari kemampuan alat merespon perubahan kadar air tanah menyebabkan katup terbuka dan tertutup sesuai dengan setpoint yang telah ditentukan. Terdapat hubungan yang erat antara perubahan kadar air tanah terhadap pertumbuhan pakcoy dengan koefisien determinasi (R2) sebesar 0,92 dan 0,799, dan terdapat hubungan yang erat antara pemberian air dengan sistem irigasi tetes otomatis terhadap pertumbuhan pakcoy dengan koefisien determinasi (R2) sebesar 0,778 dan 0,696. Sistem irigasi tetes otomatis dapat mengurangi pemborosan air irigasi.Study of Application of Automatic Watering Equipment with Drip Irrigation System Based on Changes in Groundwater Level on Pakcoy (Brassica chinensis L.Abstract. Excessive administration of irrigation water that is inconsistent with crop water requirements will affect plant growth and production. One of the irrigation models that allows to regulate the amount of water in accordance with the needs of the plant is the drip irrigation system. Irrigation scheduling automatically is very supportive when the weather is difficult to predict due to global climate change. The purpose of this research is to test the performance of microcontroller in drip irrigation system that can work automatically based on changes in soil moisture content in pakcoy plant. This research was conducted in Lambhuk village, Ulee Kareng sub-district, Banda Aceh city with land height 3,8 m above sea level with regosol land order. The research method used is the preparation phase of soil sampling to be analyzed in the laboratory, the making of drip irrigation system network, the seedbed of pakcoy seed, the preparation of planting media of 8 planting pots, the calibration of soil moisture sensor, the preparation of pakcoy seeds as well as the planting and installation of the irrigation control system Auto drops. Observation phase is measured height and number of leaf of pakcoy leaf, and weighs fresh weight of pakcoy. The result of research indicates that automatic drip irrigation control system can fulfill the water requirement of pakcoy plant based on the determination of ground water level in available water condition, with coefficient of determination (R2) equal to 0,687 . The use of automatic drip irrigation control system has an effect on the growth and production of pakcoy. There is a close relationship between soil moisture change to the growth of pakcoy with coefficient of determination (R2) of 0.92 and 0.799, and there is a close relationship between water delivery with automatic drip irrigation system to the growth of pakcoy with coefficient of determination (R2) of 0.778 and 0.696.
