Abstract

Purple sweet potato (Ipomea batatas L.) is a tuber that has purple meat and skin. The purple color of purple sweet potato is usually used by the community as a food coloring, while the sweet potato skin is considered only waste and disposed of. This study aims to determine whether purple sweet potato skin extract can be used as an alternative dye on microscopic observations of Paramecium sp. The research used experimental approach with post test only control group design. The process of purple sweet potato skin extraction using chemical solvents is ethanol, acetic acid and water. The extractions with three treatments were A, B, and C respectively different ratios (25: 1: 5), (15: 1: 15) and (5: 1:25). The results of microscopic observations quantitatively analyzed using Anova One Way test obtained sign. > 0.05 which means the purple sweet potato skin extraction results can be used as an alternative dye for microscopic observation of Paramecium sp. Qualitative analysis of the results of observations in which treatment A shows the best dye results in coloring Paramecium sp.

Abstract

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.

Abstract

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.
