Micropropagation of potato (Solanum tuberosum L.) var. Atlantic on various culture media composition

Potato is included in one of the three most important crops globally after paddy andwheat because it contributes to staple food for humans around the world. In Indonesia, potatoprioritizes its development because of non-rice carbohydrate sources and potential in fooddiversification programs. In Lampung, potato productivity decreased significantly from 2017to 2018, resulting in a negative growth rate (-33%). One of the factors that cause the lowproductivity of potatoes is the limited availability of superior seeds. Micropropagation can bean alternative to solve this problem. This research aimed to investigate the growth response ofpotato var Atlantic on various culture media and obtain the most appropriate culture media forpotato shoots induction and multiplication. This research was conducted at the Plant TissueCulture Laboratory, Politeknik Negeri Lampung, from June—September 2020. Treatmentswere single arranged in a completely randomized design with three replications, and eachreplication consisted of three culture bottles containing one explant. Data analysis usingANOVA and HSD test in 5 % alpha. Based on the result of this research, it can be concludedthat the potato var Atlantic culture showed different responses on the various components ofculture media, and MS media with 0.5 mg l2-iP is the most appropriate culture media forpotato micropropagation

USAHA PENINGKATAN PRODUKSI UBI KAYU DENGAN APLIKASI PGPR (PLANT GROWTH PROMOTING RHIZOBACTERIA) PADA PETANI DESA AGUNG TIMUR, KALIREJO, LAMPUNG TENGAH

Desa Agung Timur, Kecamatan Kalirejo, Kabupaten Lampung Tengah, sebagian besar penduduknyaberprofesi sebagai petani khususnya ubi kayu (93%). Produksi per satuan luas lahan masih sangatrendah (rata-rata hanya 12 t/ha). Tujuan dari pengabdian ini adalah meningkatkan produksi denganmenambah pengetahuan petani tentang pemakaian pupuk hayati PGPR (Plant Growt PromotingRhizobacteria). Metode yang digunakan adalah dengan penyuluhan dan praktek langsung membuatdemplot percontohan. Sebelum nya diadakan evaluasi awal terkait pengetahuan petani tentang pupukhayati, selanjutnya diakhir kegiatan juga dilakukan evaluasi yang sama dengan memberikan sejumlahpertanyaan/quesioner. Pada evaluasi awal diperoleh hasil bahwa pengetahuan petani terkait PGPRmasih sangat rendah (5%). Pada evaluasi akhir, pengetahuan petani dalam hal yang sama meningkatmenjadi 100%. Peningkatan hasil/produksi ubi kayu belum bisa dievaluasi, mengingat panen barubisa dilakukan pada bulan Maret 2021. Kata kunci: plant growth promoting rhizobacteria (PGPR), ubi kay

Barriers to the provision of smoking cessation assistance:A qualitative study among Romanian family physicians

BACKGROUND: Smoking cessation is the most effective intervention to prevent and slow down the progression of several respiratory and other diseases and improve patient outcomes. Romania has legislation and a national tobacco control programme in line with the World Health Organization Framework for Tobacco Control. However, few smokers are advised to quit by their family physicians (FPs). AIM: To identify and explore the perceived barriers that prevent Romanian FPs from engaging in smoking cessation with patients. METHODS: A qualitative study was undertaken. A total of 41 FPs were recruited purposively from Bucharest and rural areas within 600 km of the city. Ten FPs took part in a focus group and 31 participated in semistructured interviews. Analysis was descriptive, inductive and themed, according to the barriers experienced. RESULTS: Five main barriers were identified: limited perceived role for FPs; lack of time during consultations; past experience and presence of disincentives; patients' inability to afford medication; and lack of training in smoking cessation skills. Overarching these specific barriers were key themes of a medical and societal hierarchy, which undermined the FP role, stretched resources and constrained care. CONCLUSIONS: Many of the barriers described by the Romanian FPs reflected universally recognised challenges to the provision of smoking cessation advice. The context of a relatively hierarchical health-care system and limitations of time and resources exacerbated many of the problems and created new barriers that will need to be addressed if Romania is to achieve the aims of its National Programme Against Tobacco Consumption
