In Vitro Study of Potato (Solanum tuberosum L.) Tolerant to the Drought Stress

In vitro preliminary studies is candidate tolerant of potato (Solanum tuberosum L.) to the drought stress. This study aimed to determine the characters of potato after being exposed to in vitro drought stress conditions using Polyethylene Glycol PEG.  This research was conducted at the Tissue Culture Laboratory, UPT Balai Benih Induk Hortikultura Dinas Pertanian Provinsi Sumatera Utara, in Medan and other places in January 2015 until May 2015. This study used Completely Randomized non Factorial Design namely PEG (P) comprising of two levels, namely: P1 = 5 000 mg · L–1, P2 = 6 000 mg · L–1.  The results showed that increasing the concentration of PEG resulted in reduction of the percentage of plantlets survival, reduced plantlets height and plantlets dry weight but  the increase in  the total protein and leaf chlorophyll. Although the banding pattern is relatively the same, there is a brighter visible banding pattern on potato plantlets with OPAA 09  in the range of 65 bp to 75 bp with sequences of GTGGGTGCCA

Study of early screening of potato (Solanum tuberosum L.) as a result of drought stress (in vitro)

Preliminary studies in Screening of Potato (Solanum tuberosum L.) as a result of drought stress (in vitro). This study aim was to determine the limits of potato (Solanum tuberosum L.) to drought stress conditions in vitro using PEG. This research was conducted at the Tissue Culture Laboratory Unit / Laboratorium Kultur Jaringan UPT/Balai Benih Induk Hortikultura Dinas Pertanian Propinsi Sumatera Utara, Jl. Karya Jasa No. 6 Gedung Johor Medan in March 2012 to June 2012. The Completely Randomized Design (non factorial) was used with PEG concentrations of five levels, namely: P1 = 10%, P2 = 20%, P3= 30%, P4 = 40% and P5 = 50% with 5 replications. The results showed that increasing the concentration of PEG will reduce the percentage of plantlets survival, reduce plant height, number of roots and number of nodes. Treatment of 50% PEG resulted in the death of potato cuttings due to drought stress

Growth and proline content of potato Solanum tuberosum L. in vitro candidate tolerant to drought of origin callus

Screening of candidate tolerant potato (Solanum tuberosum L.) to drought in vitro from callus was aimed to determine the growth and proline content of potato plants. This research was conducted at the Laboratory of Tissue Culture of Dinas Pertanian of North Sumatra Province, Jl Karya Jasa No 6 Gedung Johor Medan, in May 2012 until May 2013. The initial research was callus formation followed byorganogenesis. Then, was treated by PEG, 1000, 2000 and 3000 ppm. The result indicated that increased concentration of PEG decreased the amount of leaves and number of internodes. The higher the PEG concentration, the higher the proline content of potato in vitro

PEMANTAUAN POLA PANGAN HARAPAN (PPH) MASYARAKAT TINGKAT KECAMATAN DI KOTA MEDAN

Efforts to obtain energy consumption based on Expect Food Pattern Score for all people of Medan City must continue to be realized to produce a healthy, active, and productive society. The purpose of monitoring in Food Consumption Pattern in 2020 is to obtain data on the community's Expected Food Pattern Score in each sub-district in Medan City during the covid19 pandemic era. Monitoring was carried out from mid-September 2020 to mid-November 2020. Each sub-district was represented by 50 households as a respondent. Sample/respondents are based on probability sampling, then the population of all respondent from 21 sub-district in Medan City become 1050 respondents. Respondents must be healthy, follow health protocols, be able to read, write and understand Expect Food Pattern Score, to be committed to participating in all activities, bring their family card and writing utensils. The monitoring results showed that each respondent from all sub-districts, there were those who consumed more types of food in certain sub-district than recommended, but some were still not as recommended in other sub-district. After processing all the data for each district, it turns out that the Expect Food Pattern Score for Medan City in 2020 is 92.29 higher than 2019 = 92.00

Peningkatan Rata-Rata Lama Sekolah (RLS) dari Harapan Lama Sekolah (HLS) di Sumatera Utara

Rata-rata Lama Sekolah (AYS) di Sumatera Utara pada tahun 2020 adalah 9,54 tahun, sedangkan Harapan Lama Sekolah (EYS) adalah 13,23 tahun. Artinya tingkat pendidikan penduduk Sumatera Utara rata-rata tamat SLTP namun peluang bersekolah adalah tamat Diploma I. Disini kita dapat melihat kesenjangan antara rata-rata lama sekolah dengan lama sekolah yang diharapkan. . Menelaah berbagai dokumentasi guna menghasilkan alternatif kebijakan dan kegiatan peningkatan angka AYS dari EYS yang pada gilirannya akan meningkatkan Indeks Pembangunan Manusia (IPM) dan mengurangi kemiskinan. Metode penulisan artikel ini adalah melalui pengumpulan berbagai peraturan dan dokumen dari pemerintah pusat hingga pemerintah daerah selama November 2021 hingga Desember 2021, kemudian dilakukan kajian untuk merumuskan berbagai kebijakan dan kegiatan dengan menggunakan statistik deskriptif. Berdasarkan analisis data, berbagai kebijakan dan kegiatan yang dapat ditempuh untuk meningkatkan rata-rata lama sekolah dari lama sekolah yang diharapkan adalah dari perspektif siswa; biaya sekolah dibebaskan, beasiswa dan bantuan pendidikan ditingkatkan, pendidikan kesetaraan dan sosialisasi. Selanjutnya dari sisi guru; perlu menambah jumlah guru, pelatihan dan sertifikasi guru serta tambahan tunjangan guru, sedangkan dari sisi infrastruktur; perlu merehabilitasi dan melengkapi fasilitas sekolah, membangun sekolah baru dan menjamin aksesibilitas lokasi sekolah berupa jalan atau jembatan, moda transportasi dan bus sekolah gratis. Semakin lama rata-rata lama sekolah semakin tinggi Indeks Pembangunan Manusia, yang berimplikasi pada tingginya pola pangan harapan rumah tangga di Sumatera Utara

Variability of organoleptic quality of Arabica coffe

Beverage quality of coffee is the most important for consumers. The objective of this research was to determine the genotypic and phenotypic variability of Arabica coffee (Coffea arabica L.). Nested design with three factors was used. The organoleptic quality of 28 genotypes was analyzed. This research revealed that most of the organoleptic qualities had low genotypic and phenotypic variations. Fragrance/aroma, flavor, aftertaste, acidity, body, uniformity, balance, sweetness, overall and total score showed low heritability and low genetic advance
