Abstract

Soybean superior varieties with high yields and are resistant to abiotic stress have been largely released, although some varieties grown in the field are not resistant to SMV. In addition, the opportunity to obtain lines of hope as prospective varieties with high yield and resistance to SMV is very small. The method for evaluating soybean germplasm is based on serological observations of 98 accessions of leaf samples from SMV inoculation with T isolate. The evaluation results of 98 accessions based on visual observations showed 31 genotypes reacting very resistant or healthy to mild resistant category to SMV T isolate  with a percentage of symptom severity of 0 −30 %. Among 31 genotypes there are 2 genotypes (PI 200485; M8Grb 44; Mlg 3288) with the category of visually very resistant and resistant, respectively and  Mlg 3288  with the category of mild resistant.  They have a good agronomic appearance with a weight of 100 seeds (˃10 g) and react negatively with polyclonal antibodies to SMV, except Mlg 3288 reaction is not consistent, despite the weight of 100 seeds (˃ 10 g). Leaf samples from 98 accessions revealed various symptoms of SMV infection in the field. This diversity of symptoms is caused by susceptibility to accession, when infection occurs, and environmental factors. Keywords—: soybean; genotipe; Soybean mosaic virus (SMV); disease severity; polyclonal  antibody

Abstract

Kebutuhan minyak kayu putih yang semakin meningkat, apabila hanya mengandalkan perbanyakan generatif tentu tidak akan mencukupi. Sebab itu, perlu dilakukan perbanyakan secara vegetatif dengan stek pucuk. Keberhasilan pengembangan stek pucuk dapat ditambahkan salah satunya pemberian Zat Pengatur Tumbuh. Ada pun ZPT yang digunakan penelitian ini yaitu NAA (Naptheine Acetic Acid) dan IBA (Indole Butyric Acid). Penelitian ini dilaksanakan pada bulan Juni hingga September 2019 di Pusat Penelitian dan Pengembangan Perum Perhutani (PUSLITBANG) Cepu. Penelitian ini bertujuan untuk membandingkan pengaruh dari pemberian konsentrasi NAA, IBA  terhadap pertumbuhan stek Kayu putih (M. leucadendron Linn) dan untuk mengetahui konsentrasi yang efektif terhadap pertumbuhan stek Kayu putih (M. leucadendron Linn). Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) faktor tunggal yaitu pemberian Zat Pengatur Tumbuh berupa NAA dan IBA. Masing-masing perlakuan diulang sebanyak 3 kali ulangan dan setiap perlakuan terdiri dari 5 tanaman sehingga diperoleh 105 unit tanaman percobaan. Peubah yang diamati yaitu jumlah daun, tinggi, panjang akar, jumlah akar, bobot basah dan bobot kering akar, bobot basah dan bobot kering tunas, dilanjutkan dengan uji Duncan taraf nyata α = 0,05 untuk mengetahui konsentrasi ZPT auksin yang paling efektif. Hasil penelitian ini terjadi berpengaruh nyata terhadap peubah jumlah daun dan tinggi stek kayu putih pada perlakuan NAA 300 ppm. Panjang akar terbaik pada perlakuan IBA 75 ppm.

Abstract

Purslane has antibacterial benefits. The diversity of purslane plants from the genus Portulaca is about 40-100 species found in tropical and four-season areas. The aim of this study was to test the in-vitro antibacterial potential of the ethanol extract of some purslane (Portulaca sp) cultivars against the tested bacteria. In-vitro antibacterial activity testing was performed using the disc diffusion method. This study used Portulaca oleracea and Portulaca grandiflora purslane cultivars. The results of the observation of the antibacterial activity testing of several cultivars of Portulaca grandiflora (K1, K3) and Portulaca oleracea (K2) against the test bacteria Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa were able to show antibacterial activity with various inhibition zones ranging between 1.56 cm and 2.86 cm. Based on the results of testing for antibacterial activity of several cultivars of purslane plant, it was shown that the sensitivity of the Gram-positive test bacteria Staphylococcus aureus was higher than the Gram-negative test bacteria Escherichia coli and Pseudomonas aeruginosa. Keywords—: Portulaca oleracea, Portulaca grandiflora, disc diffusion method

Abstract

Mikroba Bacillus subtilis merupakan agen pengendali hayati mempunyai kelebihan sebagai Plant Growth Promoting Rhizobacteria (PGPR) yaitu dapat berfungsi sebagai biofertilizer, biostimulan, biodekomposer dan bioprotektan. Tujuan penelitian mengetahui potensi B. subtilis dalam merombak bahan organik sebagai usaha meningkatkan ketersediaan bahan organik tanah yang semakin menurun. Penelitian menggunakan Rancangan Petak Terbagi dengan berbagai  bahan organik sebagai petak utama (B0 = tanpa bahan organik, B1 = kotoran ayam,  B2 = kotoran kambing, B3 = kotoran sapi) dan aplikasi B.subtilis sebagai anak petak (A0 = 0 cc/L, A1 = 5cc/L, A2 = 10 cc/L, Pengamatan meliputi variabel tinggi tanaman, indeks luas daun, jumlah buah per tanaman, berat buah per tanaman, dan bahan organik tanah. Data pengamatan  dianalisis ragam  menggunakan  Statistical Product and Service Solutions (SPSS) versi 25 dan dilanjutkan dengan uji Duncan untuk mengetahui signifikansi perbedaan antar perlakuan. Hasil penelitian menunjukkan tidak terdapat interaksi antara bahan organik kotoran ternak dan konsentrasi B. subtilis terhadap semua variabel pengamatan. Potensi B. subtilis sangat baik dalam mendekomposisi bahan organik yang ditunjukkan dengan peningkatan bahan organik, dan hasil terbaik pada kotoran  sapi (B3) dan konsentrasi B. subtilis 15 mL/L masing-masing sebesar 46.47 % dan 34.76 %. Variabel pertumbuhan tidak berbeda nyata kecuali tinggi tanaman dengan pertambahan tinggi paling banyak pada pemberian kotoran kambing sebesar 170.69 %.

Abstract

Cellulolytic fungi have an important role for the largest material flow in the biosphere. Trichoderma fungi are ubiquitous and have the ability to degrade cellulose. The study was conducted to isolate dan screen Trichoderma cellulolytic fungi from soil heaps of some organic waste. Soil samples were taken from soil heaps of some organic waste to isolate Trichoderma cellulolytic fungi. The sampling method is carried out randomly from top soil layers of organic waste litter (bagasse, sugar cane leaf, rice straw, and garbage). Isolation and screening of Trichoderma fungi are determined based on observations of macroscopic and microscopic characteristics referring to the key of fungal determination. Cellulolytic ability of Trichoderma isolates was carried out by growing on Carboxy Methyl Cellulose (CMC) media as a single carbon source by measuring the diameter of the colony and the diameter of the clear zone formed. There were 7 Trichoderma fungal isolates  that showed cellulolytic activity. Based on clear zone formation, Trichoderma harzianum showed highest cellulolytic than Trichoderma viride.

Abstract

Abstract— Uwi plants (Dioscorea sp.) as one of the types of tuber plants have the potential to support food diversity and food security in the future because it is very tolerant to be planted on dry land with a huge potential in Indonesia. The research aims to obtain a variety of diversified foods based on uwi plants. The research method used a completely randomized design laboratory scale consisting of six treatments repeated three times. These factors are the various colors of tubers used as research material including dark yellow (orange), yellow, murky white, white, purple and purple spurt. Observations include texture, elasticity, aroma, colour and taste through organoleptic tests. Instant noodles and wet noodles are used as a comparison. The study was conducted in the Agronomy Laboratory of the Faculty of Agriculture, Merdeka University, Madiun, from October to December 2018. The results showed that compared to conventional noodles as a control, the appearance of colour, taste, texture and aroma of noodles after being cooked was not much different. Whereas seen from the elasticity of uwi noodles has a lower elasticity. The difference is also in the appearance of raw dried noodles, the color and aroma are still inferior to dry noodles and instant noodles. Thus, uwi flour is potential to be developed as a food ingredient, considering that uwi carbohydrates have a low glycemic index.  Keywords—: food diversity; dry noodle; tuber color; uwi flour.
