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 aims to find out the most appropriate processing variations in reducing levels of lead metal (Pb), find out the most appropriate processing variation to maintain the calcium (Ca) content of mussel shell, and provide information about the potential of processed mussel shells as animal feed. This study used a completely randomized design method (CRD) with 4 treatments, namely, processing steamed shells (BW0), boiled (CW0), sauteed (DW0) and fresh shells as a control (AW0). Based on the results of the analysis, the treatment that reduces lead content the most is processing of boiled shells (CW0) of 815,488 ppm. Based on the results of the study, it can be concluded that the boiled processing method is the treatment that removes the highest levels of lead metal (Pb) and the steamed processing method is the most appropriate method of processing calcium content in the shell. Penelitian ini bertujuan untuk mengetahui variasi pengolahan yang paling tepat dalam menurunkan kadar logam berat timbal (Pb), mengetahui variasi pengolahan yang paling tepat mempertahankan kandungan kalsium (Ca) cangkang kijing, dan memberikan informasi tentang potensi olahan cangkang kijing sebagai pakan ternak. Penelitian ini menggunakan metode rancangan acak lengkap (RAL) dengan 4 perlakuan yaitu, pengolahan cangkang dikukus (BW0), direbus (CW0), ditumis (DW0) dan cangkang segar sebagai kontrol (AW0). Berdasarkan hasil analisis, maka perlakuan pengolahan yang menurunkan kandungan timbal paling banyak adalah pengolahan cangkang dengan cara direbus (CW0) sebesar 815,488 ppm. Berdasarkan hasil penelitian dapat disimpulkan bahwa, metode pengolahan direbus adalah pengolahan yang paling banyak menghilangkan kadar logam berat timbal (Pb) dan metode pengolahan dikukus merupakan metode pengolahan yang paling tepat dalam mempertahankan kandungan kalsium pada cangkang.Kata kunci: analisis cangkang, kalsium, kijing kokal, pakan ternak, timbal, variasi pengolahan

Abstract

The Raman Dam area has the potential to be contaminated with heavy metals due to rice field activities, near cross-regional roads as well as tourist areas and industrial areas. This has an impact on the lead content in local deer shells. This research aims to: 1. find out the most appropriate processing variations in reducing levels of the heavy metal lead (Pb), 2. find out the most appropriate processing variations in maintaining the calcium (Ca) content of kijing shells, 3. provide information about the potential of processed kijing shells as a animal feed, 4. make research results a source of information on learning biology in the form of posters. This research used a completely randomized design (CRD) method with 4 treatments, namely, steamed shell processing (BW0), boiled (CW0), sauteed (DW0) and fresh shells as a control (AW0. To measure the metal lead and calcium content of the shells, namely using Vogel's Spectrophometer UV-Vis analysis method followed by one-way Anava analysis technique and Tukey's advanced test. Based on the analysis results, the processing treatment that reduces the lead content the most is shell processing by boiling (CW0) at 815,488 ppm, while the processing treatment that can Maintaining the highest calcium content is processing the shell by steaming (BW0) amounting to 826,775 ppm. The results of this research were also developed as a source of biological information in the form of a poster.

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.
