The Effect Of Colchicine on Phenotypes And Stomata Pakcoy (Brassica Rapa L) Hydroponically With The NFT (Nutrient Film Technique) System

Colchicine (C22H25O6N) is a toxic alkaloid compound that causing a polyploidy in the plants, so it produces a robust individuals. The aims of this research are to know the effect of kolchhisin against phenotypes and stomata pakcoy (Brassica rapa L) hydroponically with the NFT (Nutrient Film Technique) system. This research used experimental method with a complete random design (CRD), five treatments and five replications. The data were analyzed by using ANAVA with 5% of credibility. The sample of this research were used pakcoy red arrow F1 nauli with colchicine P0 (Control), P1 (250 mg / L), P2 (500 mg / L), P3 (750 mg / L), P4 (1000 mg / L). The result of this study showed that the influence of colchisin against phenotype and the stomata’s size of pakcoy plant (Brassica rapa L). The high concentrations of colchicine can caused the size of the phenotype (leaves’ number, leaf area, wet weight, dry weight) pakcoy smaller than the control. While the size of the stomata increased, the largest of stomata size was found in the P3 treatment (750 mg / L).

Single Image Dehazing using Transmission Estimation

Image dehazing is a system which can reduce poor consequence of haze on pictures which increase competence of the picture/tape meting out method in the indistinct climate. The present study, presents a simple image dehazing technique. System deletes the initial transmittal, exactly depends on hidden area division which in turn reduces the initial transmittal. First, we build raw transmittal in Gaussian pyramid using selective transmittal extraction prior. Second, a patch based on Laplacian pyramid which gives the value of nonlinear re-trace function point by point. Third, is universal Laplacian map which states the segmentation-based re-traced image. All the three segmentation guide the performer for transmittal refinement. Finally, the dehazing output gets back from the refined transmittal and atmospheric scattered technique.

System Smart Urban Gardenin Based on Internet of Things

- The need for the development of technology plays an important role as the more advanced times make us have to keep up with technological advances, this plant activists have the desire to plant hydroponic methods, one of which can be used is the Nutrient Film Technique system. Basically hydroponic plants need supervision and special attention to make hydroponic plants grow as desired. So we need a special way to find out the pH of water in plants, nutrients in plants, temperature and air humidity in plants is needed by people who will plan farming activities, in the future by knowing the information from the sensors used, the community can prepare some things that need to be prepared as anticipating the possibilities that will occur. In this study, the Smart Urban Gardening tool uses the hydroponic method with the Internet Of Things based Nutrient Film Technique system, where there will be several parameters such as pH on automatic controlled water, nutrients on water to be measured, temperature and humidity, these parameters will be sent to the webserver via smartphone, in this study webserver is used, namely the keyboard as a data server to see the results of sensor readings, after the data has been sent successfully it will then be displayed on two interfaces namely android and website applications. The application used can determine the state of water ph in plants and water nutrients in plants and the temperature for the pH of the plants used are in the range 6.5 to 7.0, From the data that can be taken as a result, the pH obtained in plant water is 6 , 6 and stated to be in the appropriate rangeof plants, then the nutritional value obtained is 7.65 for temperatures of 25.9 and humidity of 56.8, so this tool can be used for hydroponic plants.

Evaluasi produksi dan kualitas inokulum fungi mikoriza arbuskula yang diproduksi dengan teknik hidroponik pada rumput Brachiaria decumbens var. mullato

<p>ABSTRAK<br /><br />Pengembangan hijauan membutuhkan pupuk ramah lingkungan. Fungi Mikoriza Arbuskular (FMA) adalah asosiasi yang melibatkan jamur dan akar yang dianggap sebagai pupuk hayati untuk meningkatkan produktivitas tanaman dan toleran dari kondisi lingkungan. Ketersediaan FMA masih jarang, sehingga dibutuhkan produksi massal untuk dapat mendukung pengembangan hijauan. Tujuan dari penelitian ini adalah untuk menghasilkan inokulum AMF menggunakan sistem hidroponik dalam jumlah besar secara efektif. Penelitian ini dibagi menjadi 2 tahap. Rancangan Acak Kelompok Faktorial yang digunakan pada tahap pertama dengan faktor A adalah jenis sistem irigasi (Manual, Drip dan Nutrien Film Technique System (NFT)) dan B adalah larutan nutrisi (AB Mix dan Hyponex Red) dengan Pueraria javanica sebagai tanaman inang. Rancangan Acak Lengkap (RAL) dilakukan pada tahap kedua dengan menggunakan produksi inokulum FMA dari tahap pertama dengan Brachiaria decumbens var Mullato sebagai tanaman inang. Hasil penelitian menunjukkan bahwa interaksi antara sistem NFT dan AB Mix signifikan (P&lt;0,05) menghasilkan bahan kering tajuk, bahan kering akar dan spora paling tinggi. Semua tipe sistem irigasi dan nutrisi menunjukkan infeksi akar&gt;96%. FMA inokulasi di Brachiaria decumbes var Mulato signifikan(P &lt;0,05) pada bahan kering tajuk, kandungan N, kandungan P dan serapan P.</p><p><br />Kata kunci: Brachiaria decumbes, FMA, sistem Drip, sistem NFT, Pueraria javanica,</p><p><br />ABSTRACT</p><p>Forage mass production development requires environmental friendly fertilizer. Arbuscular Mycorrhizal Fungi (AMF) are mutualitic symbioses between plant and fungi that considered as natural biofertilizer with benefit to improve plant productivitity and environment stress tolerance. The availability of AMF is still low, so it takes mass production to be able to support forage development. The aim of the research was to produce AMF inoculum using hydroponic system in large quantities. This research divided into 2 stages. The factorial randomized block design was used for the first stage with A factor was type of irrigation system (Manual, Drip and Nutrient Film Technique System (NFT)) and B was the nutritional solution (AB Mix and Hyponex Red) using Pueraria javanica as host plant. Completely randomized design was conducted for the second stage by using AMF inoculum production from first stage using Brachiariadecumbens var Mullat as host plant. The best result was a combination beetwen NFT system and AB Mix significantly (P&lt;0.05) produce highest shoot dry matter, root dry matter and spore production. All type of irrigation system and nutrition showed root infection &gt;96%. AMF inoculation in Brachiariadecumbes var Mulato was significant different (P&lt;0.05) on shoot dry matter, N content, P content and P uptake.</p><p><br />Keywords: AMF, B. decumbes, Drip system, NFT system, P. javanica,</p>
