Nitrogen does not directly have advantages in human physiology system, but it holds one of the most critical roles in plants’ life cycle and productivity. Even though Nitrogen is the most abundant elements in the atmosphere, it is also the most deficient essential nutrients in plants. The proposed idea of the nitrogen-fixing GM crops, particularly wheat, is aimed to overcome those stated cons of the traditional diculture and nitrogen fertilizer. This analysis focus on the overview as well as the pro and cons of the genetically modified nitrogen-fixing plants in providing a better agricultural method. The genetically modifying method to generate a nitrogen-fixing non-legumes carries a significant chance of failure results and hindrance. The multilevel implication occurs when we need to modify the plants that not normally produce nodules in their roots to form the nodules and to modify the Nitrogen-fixing microbes to live in the nodules of non-legumes, which are not their natural dwelling places.In conclusion, the genetically modified crops project to fix their Nitrogen is feasible, but the difficulties and the funds needed still outweigh the benefits obtained in the future. With all of those limitations, the target goal to erase famine in 2050 just by funding the nitrogen-fixing wheat alone seems to be too high to be reached. The funds and efforts should be better spent on other factors and farming methods.

Penelitian ini bertujuan untuk mempelajari perbandingan kadar glukosa darah tikus putih (Rattus norvegicus L.) setelah mengonsumsi suweg mentah dan suweg rebus. Eksperimen dilakukan pada 15 ekor tikus putih sehat dengan rerata berat badan 181-183 gram. Tikus dibagi menjadi 3 kelompok perlakuan. Setiap kelompok tikus normal diadaptasikan terhadap pakan selama 3 hari dan dipuasakan selama 8-12 jam, kemudian diberi pakan sesuai dengan kelompok perlakuan masing-masing pakan suweg dengan dosis 10 mg/180 g BB suweg rebus, 10 mg/180 g BB suweg mentah, dan 10 mg/180 g BB pakan standar (kontrol). Kadar glukosa darah diukur dengan glukometer pada menit ke 0, 60 dan 120 setelah pemberian pakan secara oral. Hasil menunjukkan bahwa perlakuan umbi suweg mentah menunjukkan aktivitas penurunan kadar gula darah lebih tinggi (3,8 mg/dl) dibandingkan umbi suweg rebus (3,6 mg/dl). Kecenderungan ini menunjukkan bahwa secara alami hormon insulin di dalam tubuh tikus sudah bekerja dalam menyeimbangkan kadar gula darah. Suweg mengandung senyawa bioaktif berupa Polisakarida Larut Air (PLA) dan serat pangan yang dapat membantu menurunkan kadar glukosa darah. Umbi suweg dapat diaplikasikan pada manusia khususnya sebagai terapi diet penurun kadar glukosa darah bagi penderita diabetes mellitus.

As the biggest Moslem population in the world, Indonesia still has a high dependency on importing date palms from other countries. Ajwa dates (Phoenix dactylifera L.) is one of special date palm cultivar which had cultivated since 5000 BC in arid climate area in Saudi Arabia. Adaptation and optimation of environmental factors for Ajwa dates cultivation in Indonesia are important to be conducted to meet the date palm demand of this country. A study on anatomical responses of Ajwa dates sprouts to water availability and light intensity has been conducted. Ajwa date sprouts had been exposed to combinations of three shade variations (0%, 50%, and 90% shade) and four water availability variations (25%, 50%, 75%, and 100% of the field capacity). Data were taken from day 0 until day 45 of germination. Morphological parameters which observed and analyzed were the leaf blade length and sprouts root length. Anatomical parameters which observed and analyzed were root radius, stele diameter, leaves numbers, leaves thickness, and stomatal diameter. Variations on water availability and light intensity gave the same effect (not significantly different) in almost every parameters which measured, therefore, the most optimal combination water-light treatment was still unknown. Advanced research and longer duration of experiment need to be conducted to gain the complete information regarding the optimization of environmental factors to increase the Ajwa date productivity in Indonesia.

Castanopsis argentea (Blume) A.DC. has the local name saninten. This plant is one of the woody plants that has the potential to be developed because it is beneficial for wildlife to nest and is used in reforestation. The seeds of this plant can be used for food by boiling and burning. This plant must be preserved so that it does not become extinct. However, the propagation, so it must use the technique of propagation through tissue culture. This study aims to determine the best sterilization technique for in vitro culture of C. argentea. Eight methods of explant sterilization have been carried out in this study. Methods 1-4 do not use ascorbic acid immersion, while methods 5-8 use the addition of ascorbic acid. Based on observations, it is known that the best sterilization is in the 8th method because the level of contamination and browning is lower than other methods, namely on the fifth day after planting only 20%. The 8th method is graded sterilization. In graded sterilization, explants were gradually immersed in 10% NaOCl, 20% NaOCl, and 30% NaOCl, respectively. Multilevel sterilization is the most effective method of sterilization to reduce contamination and browning. Ascorbic acid acts as an antioxidant and reduces contamination in the enzymatic browning reaction. The combination of sterile substances, time, sequence, and method of immersion affects the sterility of explants.
