Abstract

Salinity area experienced an expansion that is the caused contamination of irrigation water, seawater intrusion, drought stress and excessive uses of fertilizers.varieties is one of the plant breeding programs to resolve the salinity problem, before that, however, the breeder must know plant adaptation mechanisms in morphology, physiology and biochemical so that the plant can be categorized adapt and as having potential for the tolerant varieties. This writing aims to know the action of genes through skewness and kurtosis estimation pattern Na, K, and chlorophyll content, so it is known if plant-able to adapt with salinity. This research used a destructive analysis. (A) Anjasmoro varieties, (G) Grobogan varieties, (N) Grobogan varieties that have been through repeated selection as a comparison. Research result shows the tolerant varieties having high K + ions.

Abstract

The research was conducted at the Development University of Pancabudi, the agricultural lab of Glugur Rimbun starting from January until April 2020. This research was conducted using an experimental method using a Randomized Block Design (RAK) with 4 treatments and 6 groups/replication. The observed plant response was in the form of a plant height variable (cm), several leaves (strands), wet weight of plants (g), dry weight of plants (g), root length (cm), and organoleptic test. Based on the research results obtained, then it can be concluded that hydroponic nutrition with a concentration of 450 ppm (P1) has a good effect on the growth of red lettuce plants, namely producing high18.64 cm at the 4th week and the number of leaves 21.80 at the 4th week, weight 114.22 g in wet, 5.94 in dry, and 29.18 cm in root length.

Abstract

Dendrobium merupakan anggrek epifit, tumbuh menempel pada tumbuhan lain. Dendrobium memiliki keragaman yang tinggi  karenanya teknik kultur jaringan sangat membantu dalam perkembangbiakannya. Medium yang digunakan mengandung nutrisi yang dideferensiasi kecocokannya seperti penggunaan arang aktif dan penambahan ZPT yang dalam penelitian ini BAP (Benzil Amino Purine). Penelitian ini bertujuan untuk mengetahui keberhasilan dan perkembangan perbanyakan vegetatiftunas tanamann Anggrek Dendrobium sp dengan pemberian BAP dan Arang Aktif sebagai media dan ZPT secara in vitro. Penelitian ini dilaksanakan di Laboratorium Kultur Jaringan Universitas Pembangunan Panca Budi, Medan dari Juni hingga Agustus 2019. Teknik pengerjaan dilaksanakan melalui tahapan dalam metode kultur jaringan, dengan 2 faktor perlakuan. Faktor pertama: Media padat Arang aktif, A1= 1 gr/l, A2= 2 gr/l, A3= 3 gr/l. Faktor kedua zat pengatur tumbuh BAP  terdiri dari 3 taraf yaitu, B0= tanpa BAP, B2= 1ml/l, B3= 2 ml/l. sehingga didapat 12 kombinasi perlakuan dan diulang sebanyak 3 kali. Metode analisis data untuk menarik kesimpulan menggunakan Rancangan Acak Lengkap Faktorial metode linier.Parameter amatan meliputi jumlah daun (cm), jumlah tunas, tinggi tanaman (cm), jumlah akar dan panjang akar (cm). Hasil penelitian menunjukkan penggunaan arang aktif menunjukkan hasil berbeda nyata terhadap jumlah daun dan jumlah akar tetapi tidak berpengaruh nyata terhadap jumlah tunas, tinggi tanaman dan panjang akar. Zat pengatur tumbuh BAP tidak berpengaruh nyata terhadap jumlah daun, jumlah tunas, tinggi tanaman, jumlah akar dan panjang tanaman.

Abstract

Arabica coffee (Coffea arabica L) is one of Indonesia”s mainstay plants to develop the world's largest coffee producer. The high level of demand for coffee bean products requires the provision of large quantities and quality seeds. Nursery is the first step in coffee cultivation which affects productivity and crop production. The latest biofertilizer innovation is to utilize phosphate solubilizing microorganisms as biological fertilizers. This study aims to determine the effect and interaction of the addition of rhizosphere bacterial suspension and bacterial capsules on Arabica coffee plants. The research design used was a completely randomized design (CRD), consisting of 16 treatments with 2 replications. The first factor was the administration of a rhizosphere bacterial suspension consisting of R0:0 .ml, R1:10 ml:R2:20 ml, R3:30 ml and the second factor was the addition of a bacterial capsule consisting of A0:0 gr, A1:10 gr, A2. :20 g, A3:30 g. Isolates from oil palm soil obtained 14 isolates of rhizosphere bacteria. The best observation of plant height was the R3 treatment (24.55 cm). The observation of the number of leaves was R3 (15,25 cm). for the leaf area parameter the highest number was obtained R3 (25.53 cm). The test results showed that the application of suspension microcapsules and rhizosphere bacteria significantly increased the growth of Arabica coffee (Coffea arabica L)Key words: Rhizosphere bacteria, suspension, microcapsules INTISARIKopi arabica (Coffea arabica L) merupakan salah satu tanaman andalan Indonesia dalam perkembangan penghasil kopi terbesar di dunia Tingginya laju permintaan akan produk-produk biji kopi menuntut penyediaan bibit dalam jumlah besar dan berkualitas. Pembibitan merupakan langkah awal dalam pembudidayaan kopi yang berpengaruh terhadap produktifitas dan produksi tanaman. Inovasi pupuk hayati yang terbaru adalah memanfaatkan mikroganisme pelarut fosfat sebagai biofertilizer. Penelitian ini bertujuan untuk mengetahui pengaruh dan intraksi  penambahan suspensi bakteri rhizosfer dan kapsul bakteri terhadap tanaman kopi arabica.  Rancangan penelitian yang digunakan adalah rancangan acak lengkap ( RAL), terdiri 16 perlakuan dengan 2 ulangan. Faktor pertama adalah pemberian suspensi bakteri rhizosfer yang terdiri dari R0: 0 ml, R1:10 ml: R2:20ml, R3:30 ml dan faktor kedua adalah penambahan kapsul bakteri yang terdiri dari A0: 0 g, A1: 10 g, A2:20 g, A3: 30 g. Isolat dari tanah kelapa sawit diproleh  14 isolat bakteri rhizosfer. Pengamatan tinggi tanaman terbaik adalah perlakuan R3 (24,55 cm) pengamatan jumlah daun adalah A2 (15,25 cm). untuk parameter luas daun angka tertinggi diperoleh R3 (25,53 cm). Hasil pengujian menunjukkan bahwa aplikasi mikrokapsul suspensi dan bakteri rhizosfer secara nyata meningkatkan pertumbuhan tanaman kopi arabica (Coffea arabica L). Kata kunci: Bakteri Rhizosfer, suspensi, mikrokapsul
