Moringa leaves contain antioxidants to neutralize and stabilize free radicals in the body. Moringa exploration is important for the purpose of finding trees to be used as sources of superior seeds. This study aimed to obtain a Moringa tree with the highest antioxidant content. An exploration had been carried out from June to July 2021 in four cities/regencies in West Sumatra, namely Padang City, Solok City, Pesisir Selatan Regency, and Solok Selatan Regency. Coordinate data were analyzed using ArcGIS, and antioxidant activity test results were analyzed using the DPPH method. From the exploration, 36 Moringa trees were found with different characters. The results of the testing of the antioxidant activity of leaf extracts showed that there were 3 parent trees that had high antioxidant activity, marked by the lo...

Penuntun ini disusun dengan harapan dapat menjawab tantangan akan kebutuhan proses pembelajaran yang utuh dan ideal dengan konsep pertanian berkelanjutan.

To increase the productivity of patchouli, quality seeds are needed. Patchouli propagation can be performed by in vitro culture such as direct or indirect organogenesis. The purpose of this study was to obtain the types of explants and composition of the media to inducing shoot through direct organogenesis. The research used a factorial completely randomized design. The first factor was the type of explants [leaves and nodus], the second factor was the concentration of BA [0.3, 0.4, and 0.5 ppm]. Data were analyzed using the F test and Duncan as posthoc test using the STAR [Statistical Tool for Agricultural Research]. The results showed shoot induction time varies from 9.3-21.7 days after culture. BA with 0.3 ppm gives the best performance in a number of the shoot and shoots height about 16.3 shoots and 2.1 cm, respectively.

Suhu tinggi pada tanaman adalah terdenaturasinya protein, peningkatan fluiditas membran sel, enzim-enzim inaktif, sintesa protein terhambat dan kehilangan integritas membran. Pendekatan utama yang dapat digunakan untuk melihat kemampuan ketahanan tanaman terhadap cekaman suhu tinggi secara morfologi yaitu dengan melihat pertumbuhan tunas dan kemampuan sistem perakaran dalam menyerap air. Tujuan dari percobaan ini adalah untuk melihat pertumbuhan kecambah tiga varietas gandum pada beberapa kondisi suhu inkubator. Percobaan disusun berdasarkan rancangan acak lengkap faktorial. Faktor pertama adalah varietas gandum, yang terdiri dari tiga taraf (Dewata, Nias dan Selayar) dan faktor kedua adalah suhu, yang terdiri dari tiga taraf (25, 30, 35 oC). Hasil penelitian menunjukkan bahwa meningkatnya suhu hingga 35oC sangat mempengaruhi semua peubah yang diam...

Tingginya jumlah impor menyebabkan Indonesia tidak memiliki kemandirian dalam mencukupi kebutuhan pangan masyarakatnya. Pengembangan budi daya gandum di Indonesia terkendala oleh faktor suhu yang lebih tinggi dibandingkan dengan daerah asalnya. Dalam rangka pengembangan gandum perlu dilakukan perakitan varietas unggul gandum tropika yang mampu beradaptasi dengan lingkungan melalui hibridisasi, induksi mutasi, kultur jaringan, maupun transformasi genetik. Kultur in vitro melalui jalur embriogenesis somatik memainkan peranan yang sangat penting dalam perbaikan genetik tanaman dan integrasinya dengan program pemuliaan konvensional maupun teknik molekuler dan bioteknologi memungkinkan embriogenesis somatik menjadi cara dalam perakitan varietas unggul tanaman. Namun, hal ini sangat tergantung pada metode keberhasilan regenerasi eksplan menjadi tanaman utuh, sehingga pemantapan protokol embrio...

Study Design: Completely randomized design. Place and Duration of Study: The research was conducted in screen house of Faculty of Agriculture, Andalas University, Padang, Indonesia from April to December 2018. Methodology: Completely randomized design was used in the assay. The treatment was 10 Si sources (No silica, Si 1 ppm, Si 2 ppm, Si 3 ppm, husk charcoal 50 g/plant, husk charcoal 100 g/plant, husk charcoal 150 g/plant, husk ash 50 g/plant, husk ash 100 g/plant, husk ash 150 g/plant). The variety was Anak Daro. Each treatment was replied 3 times so that 30 experimental units were obtained. The data was analysed by using F test in 5% and followed by Duncan’s Multiple Range Test (DNMRT) in 5%. The data analysis using software Statistic Tool for Agricultural Research (STAR). Results: Silica sources affected the agronomic and physiological characters of rice plant. ...

Genetic improvement on tolerance to high temperatures is necessary for development of wheat in Indonesia. The purpose of this study was to determine the level of radiosensitivity to be used as the basis for the induction of mutations by gamma ray irradiation on embryogenic callus to obtain putative mutants with high temperature tolerance. Explants used were embryogenic callus cultured on MS medium containing 30 g L-1 sukrosa, 2 g L-1 gelrite, 2 mg L-1 2.4D and 1 mg L-1 picloram. Culture incubated for 6 weeks with temperature 20±4 oC in the room culture. Five irradiation doses (10, 20, 30, 40 and 50 Gy) were used in radiosensitivity testing. A factorial, completely randomized design was applied to the experiment. The first factor was selection temperature with three levels (25, 30 and 35 oC), and the second factor was doses of gamma ray iradiation with three leve...
