Abstract

ABSTRACTNutrient Enhancement In Cereal Crops Using Actinobacterial EndophytesWheat high demand without sufficient production and Actinobacterial endophytes usage limitation inIndonesia motivated this research. The aim was to determine Actinobacterial endophytes effect on nutrientenhancement in wheat (Triticum aestivum L.). It was hypothesized that they can enhance wheat nutrient.The experiment stages were: 1) Pot-Trial I, confirming nutrient enhancement using Actinobacteria in 6 soiltypes; 2) Pot-Trial II, screening Actinobacteria strains; and 3) Field-Trial. The results showed thatActinobacteria effects varied for different nutrients and site based differences. In Pot-Trial I, different soiltypes significantly affected the manganese and zinc content (P=0.00 and P=0.01), but not inoculation ofActinobacteria nor the combination of them. Field Trials showed the same trends. Combination betweenthose treatments significantly affected manganese content (P=0.045). Nutrient analysis on xylem sap in PotTrials 2 only showed the value differences since there was insufficient collected volume to be statisticallyanalyzed. Zinc and iron contents were the highest in Actinobacteria EUM165 treatment and the highestmanganese content in Actinobacteria EN16. In conclusion, wheat nutrient content is affected byActinobacteria and different soil types but there was insufficient evidence to generally conclude that it canbe enhanced. They have their own effects and affected each other in enhancing nutrient content.Keywords: Nutreint, wheat, endophytic ActinobacteriaABSTRAKTingginya permintaan gandum tidak disertai produksi yang cukup, serta terbatasnya pemanfaatanActinobacteria endofit di Indonesia, melatarbelakangi penelitian ini. Tujuannya untuk mengetahuipengaruh penambahan Actinobacteria endofit terhadap nutrisi gandum (Triticum aestivum L.). Diduga,penambahan Actinobacteria endofit dapat meningkatkan kandungan nutrisinya. Tahapan penelitianmeliputi: 1) Uji-Pot I, mengonfirmasi peningkatan nutrisi gandum menggunakan Actinobacteria pada 6 jenistanah; 2) Uji-Pot II, menguji berbagai strain Actinobacteria terhadap peningkatan nutrisi gandum; serta 3)Uji Lapangan. Hasilnya menunjukkan bahwa Actinobacteria meningkatkan nutrisi gandum secara berbedatergantung nutrisi yang diuji serta jenis tanah yang digunakan. Pada Uji-Pot I, jenis tanah berpengaruhnyata terhadap kandungan mangan dan seng (P=0.00 dan P=0.01), tapi pemberian Actinobacteria maupunkombinasi keduanya tidak. Uji Lapangan menunjukkan hasil yang sama. Kombinasi kedua perlakuanmeningkatkan kandungan mangan secara signifikan (P=0.045). Analisis cairan xilem dari Uji-Pot IImenunjukkan perbedaan hasil tanpa uji statistik karena terbatasnya cairan yang dikumpulkan. Kandungantertinggi seng dan zat besi ditunjukkan oleh perlakuan Actinobacteria EUM165 dan mangan yang lebihtinggi oleh Actinobacteria EN16. Disimpulkan bahwa kandungan nutrisi tanaman gandum dapatdipengaruhi oleh pemberian Actinobacteria endofit serta perbedaan jenis tanah, namun tidak cukup buktiuntuk menyimpulkannya secara umum. Baik jenis tanah maupun Actinobacteria endofit memiliki pengaruhsendiri serta saling mempengaruhi terhadap kandungan nutrisi tanaman gandum.Kata kunci: Nutrisi, gandum, actinobacteria endofit

Abstract

This study analyzed the effect of chromium metal accumulation on magnesium absorption and chlorophyll content in vegetables. The effect of accumulation was determined by performing controlled experimental methods on planting media supplemented with chromium and by directly observing vegetables grown in chromium-polluted areas, such as mountain, rice field, street, and industrial areas. The controlled experiments were carried out by varying the chromium contamination (1 and 3 ppm) and magnesium nutrition (0.4, 0.6, and 0.8 g/L) in planting media. The controlled experiment was compared with the results of field observation in several chromium-polluted areas. The effect of the treatment was analyzed based on the chlorophyll and magnesium levels in the leaves in comparison with the chromium levels in the planting medium. The results of observation and controlled experiments showed that the accumulation of chromium in plants affected the absorption of magnesium, which also affected chlorophyll formation and thus disrupted plant growth. The high chromium level (3 ppm) and magnesium level in planting media can reduce the accumulation of chromium in kale stems and leaves by 19% and 33%, respectively, increase magnesium absorption on kale stems and leaves by 7% and 5%, respectively, and increase chlorophyll formation on kale stems and leaves by 12% and 11%, respectively. Field observation in several chromium-polluted areas showed that spinach has a better chromium accumulation tolerance than kale in terms of magnesium absorption. The type of planting media, plant species, and the presence of other metal contaminants also affect chromium accumulation, magnesium absorption, and chlorophyll level.

Abstract

Unmanned Aerial Vehicle (UAV) remote sensing is recommended to evaluate damage quickly and quantitatively. Therefore, this study aimed to explore the use of RGB aerial images by UAV for evaluating drought damage of rice through canopy color and coverage. The procedures were conducted in the dry season of 2018 (August – September 2018) at the Balitkabi Experimental field, Muneng, Probolinggo, Indonesia. A split-plot experimental field design was used with 2 factors, namely drought treatments at growth stage (Vegetative/P1, Reproductive/ P2, Generative/P3, and Control/P0), and varieties (Jatiluhur/V1, IPB9G/V2, IPB 3S/V3, Hipa 19/V4, Inpari-17/ V5, Mekongga/V6, Mentik Wangi/V7, Ciherang/V8). Canopy temperature data were then obtained using FLUKE 574 Infrared Thermometer, while images were taken with an RGB camera (Zenmuse X5) attached to Drone DJI Inspire I. The images were taken twice during the treatment (4 DAT and 15 DAT), followed by analysis using QGIS 2.18 and ImageJ. The results showed that RGB aerial images by UAV could be used in agricultural insurance in Indonesia, and similar countries around the world. Although the effect on yield needed to be evaluated, quick assessment by UAV was still an effective tool. In addition, drought damage evaluation through canopy color was better than canopy coverage in terms of analysis. The conversion from RGB to Lab color space increased the determination coefficient in multiple regression of color values against temperature difference (Tc-Ta).

Abstract

One way to decompose pond waste sediment is by using the liquid nutrient culture media (NB) called Pumakkal as a starter formula. However, bioremediation in shrimp ponds has received less attention, despite being massively promoted by the government. East Lampung has produced 11.6 million m3 of liquid and 4.077 m3 of sediment waste in shrimp ponds. They are rich in organic matter, but possibly poison the pond if uncurbed. This study investigated in what manner Pumakkal decomposed shrimp pond waste under three parameters: macronutrient and micronutrient contents, and pH. The experiment was conducted using a completely randomised design (CRD) with 15 factorial arrangements. The sample was 65 kg of shrimp pond waste and 65 litres of liquid waste, which were analysed with five treatments: three of liquid waste media (LW), sediment waste (SW), and mixed liquid and sediment waste (MLS). The results showed that the treatment of the CE 15-isolate in MLS significantly improved the fertiliser quality (p<0.05). Pumakkal CE worked the finest in MLS, producing the fertiliser with the best macronutrients: Nitrogen (N) 1,3%, Phosphorus (P)2,3%, and Potassium (K) 2,3%; C-organic 23%, C/N ratio 29; micronutrient: Fe:155 ppm, Cu: 51 ppm, Zn: 72 ppm, Mn; 51 ppm, B; 25 ppm, and Mo: 8 ppm, and pH 5-6. The mixture of liquid and pond sediment waste produces the best fertiliser suitable for plant fertiliser users. The study concludes that Pumakkal is effective in decomposing harmful waste sediment to support the bioremediation program.
