Abstract: Abstract. Hidayah BN, Herawati N, Aisah AR, Utami NR. 2021. Diversity of fungi associated with rhizosphere of healthy and diseased garlic crop. Bio ersitas 22: 1433-1440. Garlic (Allium sativum L.) is an especially important horticultural crop in Indonesia because it is used as a cooking spice and for medicines and cosmetic ingredients. It is mostly grown in irrigated highlands however Indonesian production is only supplying at most 17.5% of domestic demand. West Nusa Tenggara (WNT) Province is one of the largest garlic-producing regions in Indonesia. Currently, garlic cultivation in WNT Province is facing a problem of root rot disease. Therefore, it is necessary to investigate the fungi associated with garlic root rot disease. Research was conducted in June – September 2018 and s les were collected from Sembalun highlands (1200 m above sea level). Seventeen fungal isolates were collected from the rhizosphere of the garlic crops and fourteen of them were identified. The fungi isolated from the rhizosphere of healthy garlic crops were from the genus Aspergillus, Penicillium, and Paecilomyces. While the fungi isolated from the rhizosphere of diseased garlic crops were from the genus Aspergillus, Penicillium, Paecilomyces, Fusarium, and Phoma. The genus Fusarium and Phoma are well known as plant pathogens.

Abstract: Based on the Regulation of the Minister of Education and Culture of the Republic of Indonesia Number 22 of 2016 concerning Basic and Secondary Education Process Standards that the learning process can be carried out by utilizing information and communication technology to improve the efficiency and effectiveness of learning. In accordance with the era of industrial revolution and increasingly sophisticated technological developments, requires that educators can integrate technology with the content of learning materials. The results of previous studies indicate that most teachers in Jember Regency are considered not creative, only 30 percent of teachers are creative and literate in information technology and as many as 70 percent of teachers are not creative, they still teach with conventional techniques, without using information technology. The purpose of this study is to analyze the technological content knowledge of historical educators in Jember Regency. This type of research is descriptive research. Data collection methods in this study are questionnaire. The questionnaire technique carried out by researchers was by distributing questionnaires or questionnaires to educators using a self assessment, with the help of Statistical Package for the Social Si (SPSS) version 22 program. Based on the results of descriptive statistics the level of technological content knowledge history educators in Jember Regency scored (M = 3.29, SD = 0, 417), 60.6% of Technological content knowledge history educators in Kabupaten Jember are at a good level. And as many as 27.3% are at a sufficient level. Then at a low level of 12.1%, while at a very low level and very good at 0%. So, it can be concluded that the level of technological historical knowledge content in Jember Regency is at a good level.

Abstract: Pod sucking pest, Riptortus linearis , is one of the important pests on soybeans which cause high yield losses. In order to reduce yield loss, information related to the development stages of resistant varieties and appropriate cultivation technology is needed. This study aimed to determine the relationship between the development stages of soybean varieties and cultivation technology on the population and intensity of pod sucking pests, R. linearis , attack and soybean yield. The study was conducted in a split plot design with two factors, namely cultivation technology [recommendation technology (TR) and existing technology (TE)], and soybean varieties: [Detap-1 (V1), Dega-1 (V2), Anjasmoro (V3), Biosoy (V4), and Dena-1 (V5)]. Each treatment combination was replicated three times resulting in 30 experimental plots. The results showed that soybean varieties affected the population and intensity of R. linearis . Development stages of soybean varieties that positively correlated with pest populations were plant height with a correlation coefficient value r =0.52, followed by pod trichome density ( r =0.12), and the number of pods attacked ( r =0.49). While the character that correlated with the intensity of pest attack was the density of trichomes ( r =0.20). Recommended cultivation technology can increase soybean productivity between 0.1 – 0.47 ton/ha compared to farmers’ existing technology.

Abstract: The response of soybean crop to organic fertilizers has not been fully understood in Indonesia. This research aims to investigate the response of new superior variety of Anjasmoro soybean to phosphorus and organic fertilizers in the dry climate ricefields. The experiment was conducted in Sesela Village, West Nusa Tenggara Province, Indonesia from August - November 2015 using a randomized 2-factor design. The first factor was phosphorus fertilizer with 4 levels: 0 kg/ha, 36 kg/ha, 72 kg/ha and 108 kg/ha. The second factor was organic fertilizer with 4 levels of fertilizer dosage: 0 ton/ha, 2.5 tons/ha, 5 tons/ha and 7.5 tons/ha. Parameter observed were plant height, number of leaves, number of nodules, number of productive branches, number of pods, number of empty pods, dry weight, weight of 100 seeds, and production. The results showed that the optimum dose of organic fertilizer was 7.5 tons/ha with the highest number of pods of 100. This was confirmed by the regression value (R 2 ) of 0.97 which indicates that organic fertilizer affects the increase in the number of pods in a quadratic. Phosphorus fertilizer has an effect on the number of empty pods, number of productive pods, number of pods, productivity and production of soybean.

Abstract: Plant growth is influenced by seed quality. Seeds need to be treated to prevent pest and disease disorders or to increase seed germination. Soybean planting was carried out in this study by the treatment of varieties and seed pre-treatment application before planting. The study aimed to measure the growth and yield of soybeans by varieties and seed treatment before planting, carried out in the Village of Nggembe, District of Bolo, Bima Regency. The study used factorial randomized block design with two factors. The first factor was soybean varieties consisting of two levels, namely Devon and Dena varieties, and the second factor was the application of pre-planting seed treatments consisting of four levels namely Cruiser, Marshall, Agrisoy, and without seed treatment, each treatment was repeated three times. Observations were made on the performance of agronomic crops and soybean yields. The results showed that the treatment of soybean varieties and the application of seed treatment had a significant influence on plant height and soybean productivity, and both treatments had interactions on parameters of plant height, number of filled pods, weight of 100 seeds, and soybean productivity with the best results successively produced by a combination of Devon-Control, Devon-Marshall, Devon-Agrisoy, and Dena-Cruiser.

Abstract: Indonesian new superior varieties of soybean are continually released as an effort to increase soybean productivity. Some new superior varieties such as Devon 1, Dena 1, and Dega 1 were not widely known by the stakeholders. This research aims were to investigated the growth and yield of five Indonesian new superior varieties of soybean in the dry climate rice field. The experiment was conducted from March to July 2018 in Segala Anyar Village of Central Lombok Regency, West Nusa Tenggara Province, Indonesia. The experimental design was used non-factorial randomized block design with the soybean varieties as treatments (Devon 1, Dena 1, Anjasmoro, Argomulyo, and Dega 1). Each treatment was repeated four times. The parameters observed included plant height, number of branches, number of leaves, number of sections, number of pods, and soybean production. Data were collected from 10 crop s les for each replication during vegetative phase 1 and 2. The results showed that the soybean varieties had a significant effect on plant height, number of branches, number of sections and production. The crop could not produce optimally during field experiment due to lack of water in the pod-filling phase. Generally, it could grow well and has ability to produce yield.
