Teknologi Produksi Benih Kentang untuk Mewujudkan Kemandirian Benih di BUMDes Desa Batur

The area at the foot of Mount Merbabu, more precisely in Batur Village, has an altitude of 1,200‒1,800 meters above sea level, so it is very suitable for cultivating potato plants. Several farmers have cultivated this, but the production results are not always optimal. The potato crop productivity problems faced by farmers in BUMDes are: 1) Limited quality seeds; 2) The price of seeds is high and difficult for farmers to reach; 3) Farmers use seeds from some crops that are not of good quality so the yield is low and susceptible to disease; and 4) Farmers are unfamiliar with the technology for producing superior potato seeds. The University of Muhammadiyah Malang has superior virus-free seed sources and technology that can be adopted and disseminated to farmers to produce quality seeds independently so that they can overcome the problems they face. Activities are carried out in a participatory manner using tutorial methods, training and demonstration plots at locations, and group mentoring. Partners agree to actively provide human resources, necessary facilities, and accompanying funds in implementing activities. At this time, farmers have understood planet acclimatization technology. They can produce 5,000 mini cuttings from 500 acclimatized broodstock, 10,000 G0 seeds, and 25 tonnes/ha of G2 seeds using rooted shoot-cutting technology. Additionally, partner farmers have obtained permits as seed producers from BPSB (Seed Supervision and Certification Center). This program is ongoing, and UMM will assist on an ongoing basis until the establishment of an independent BUMDes for potato seeds in Semarang Regency.The area at the foot of Mount Merbabu, more precisely in Batur Village, has an altitude of 1,200‒1,800 meters above sea level, so it is very suitable for cultivating potato plants.

Effect of Phenylalanine Amino Acid on Flavonoid Production by Apple Callus Culture

Apple (Malus domestica) is a fruit with many health benefits because it contains phytochemicals and flavonoids. Flavonoids are phenolic compounds with potential as antioxidants, which can neutralize free radicals that enter the human body. Flavonoid production can be done through callus culture. Adding phenylalanine amino acids to apple callus can increase the flavonoid content. The research aimed to study Phenylalanine amino acids’ effect on apple callus’s flavonoid content. The total content of flavonoids in the callus of 3 apple varieties, namely Granny Smith, Red Delicious and Manalagi, in MS + 2,4-D 0.5 ppm + BAP 1 ppm added phenylalanine (01000 ppm) higher than total flavonoids fresh skinless apples. Green callus has more potential to produce flavonoids compared to brown callus. Suitable media for producing flavonoids in vitro are MS + 2,4-D 0.5 ppm + BAP 1 ppm + phenylalanine 500 ppm for Granny Smith and Manalagi apple callus, which produce total flavonoid 1.51 (QE) mg/g DW and 0.78 (QE) mg/g DW, MS + 2,4-D 0.5 ppm + BAP 1 ppm + without Phenylalanine for Red Delicious callus produce total flavonoid 1.46 9(QE) mg/g D
