Wilczek] is very important to avoid drought stress, pest and disease attack as well as increase the index planting. The aims of this research was to estimate genetic variability and correlation. The genetic study included heritability, coefficient of genetic variability, genetic advance and correlation among yield components so that it can be used as selection criteria for early maturity mungbean. A total of 145 accessions of mungbean were tested at Muneng farm station in March-June 2010 using a randomized block design, with two replicates. Each accession was planted at 0.8 m x 4 m with spacing 40 cm x 10 cm, with two plants/hole. Fertilization was done by adding 50 kg urea, 75 kg SP36, and 75 kg KCl/ha, at the time of planting. The results showed that mungbean accesions had significant differences in all characters tested. The genetic variance value of all characters was broad with high broadsense heritability estimates, except for number of pods/ cluster and seed number/pod. Genetic advance of all characters were high, except for seed number/pod. The phenotypic correlation between 1000 seeds weight and pod length with seed yield were positive significant while plant height, flowering days, days to maturity, and number of pods per plant had negative significant correlation with its yield. Therefore, plant height, days to maturity, pod lenght, 1000 seeds weight and seed yield could be used as selection criteria based on estimating value of genetic variability, correlation with yield and economic value. There were five genotype which have index value above 20, i.e MLGV 0353, MLGV 0362, MLGV 0354, MLGV 0358, and MLGV 0351.</p><p> </p><p><strong>Abstrak</strong></p><p>Kacang hijau [Vigna radiata (L.)

No full textSalinity Tolerance of Mungbean Genotypes at Seedling Stage
Full text linkSalinity is a major abiotic stress limiting mungbean production worldwide including Indonesia. Since mungbean plant is very sensitive to salt condition, selection of salinity tolerant genotypes becomes important for mungbean improvement. The objective of this study was to evaluate the tolerance of eight mungbean genotypes to salinity at seedling stage under different levels. The experiment was arranged in a randomized complete block design with two factors (mungbean genotypes and salinity levels) and triplicates. Observation variables were germination percentage, vigor index, germination rate, hypocotyls length, epicotyls length, root length, number of root, seedling fresh weight, and seedling dry weight. The result showed that increasing level of salinity concentration inhibited the speed of germination, germination percentage, vigor index, normal seedling fresh weight, and number of lateral roots. Murai and Vima 1 were identified as tolerant genotypes, while Vima-2 and MLGV 0180 were identified as salinity sensitive genotypes at seedling stage. Currently, mungbean varieties with special characters, such as saline-tolerant is not yet available. The availability of saline-tolerant variety of mungbean is a cheaper and easier technology for farmers to anticipate the expansion of the saline area. The tolerant genotypes may be further tested at the later stage to obtain promising genotype tolerant to salinity that effectively assist mungbean breeding program

Potential yield of tidal swamp-adaptive soybean promising lines
No full textThis study was carried out in order to identify suitable soybean lines that were adaptive in tidal swamp land. The research material consisted of 10 soybean promising lines and two varieties (Lawit and Menyapa). The research was carried out in Wanaraya, Barito Kuala, Indonesia, in rainy season 2014. The results showed that among of the 10 soybean lines, Snb/1087-148-2-1 reached the largest grain size (10.04 g/100 grains), followed by Snb/1087-147-2-7 (9.72 g/100 grains) and significantly different to Menyapa (6.86 g/100 grains) and Lawit (9.25 g/100 grains). Although these two lines had larger grain size than Menyapa, but the grain yield per unit area of these two lines were lower. Menyapa produced 1.67 t/ha, while Snb/1087-148-2-1 and Snb/1087-147-2-7 produced 1.18 and 1.42 t/ha respectively. Lower grain yield of these two lines was due to the smaller number of filled pods when compared to Menyapa variety.</jats:p
Utilization of Genetic Variability in Mungbean as Food Industrial Raw Material in Indonesia
No full textThe Effect of Seed Position in Pod on The Seed Viability of Cowpea (Vigna unguiculata)
Full text linkIn Indonesia, cowpea (Vigna unguiculata L. Walp) is widely cultivated in the dry climate area. Famers used the seeds from previous plants or traditional markets. The aims of the study were to determine the effect of seed position in the pods on seed viability and to study the seed and seedling characteristics regarding the genetic variation and seed position. The cowpea used in this study was from 18 Indonesian local varieties. Twenty-five matured pods were randomly detached from each variety. Each pod was divided into three parts, i.e. the lower third (base), the middle third, and the upper third (tip). The seeds of each part were germinated using sand media to evaluate their viability. Each local variety has different response to the percentage of seed viability in each seed position in the pod. The highest abnormal germination occurred in the seed from lower part of the pod, followed by seed in the middle of the pod and the tip of the pod. The variation of seed viability in pods was more determined by genetic differences in local varieties. The average seed viability from three parts of the pods was highest for seeds originated from local varieties of Lumajang and Sampang. Therefore, it is recommended that the seeds of both local varieties can be mixed to be used for optimum cowpea cultivation

Full text linkGenotype x environment interaction always presents in soybean multilocation trials in Indonesia. The objective of the research was to determine the performance of yield and yield components of soybean promising lines in two locations. A total of 11 promising lines, and three check varieties (Tanggamus, Wilis, and Anjasmoro) were evaluated in NTB and DIY in dry season 2013. The design was randomized complete block design with three replications. The results showed that yield and yield components were influenced by locations, genotypes and genotypes x locations interaction, except for days to maturity which was not influenced by the location. Number of filled pods had a significant positive correlation with grain yield of soybean. TGM/Anj-773 line had high average yield at two locations and higher than the check variety (Tanggamus)
Author compliance in following open journal system of communication science in Indonesia
Full text linkThis study aims to test the theory proposed by D. Cuilier (2010) that compliance
gaining has a correlation with the availability of information access. In this study, hypothesis
testing is done on the phenomenon of influence between the availability of information in Open
Journals System (OJS) in the field of communication science in Indonesia to the compliance of
the author. In order to fulfill the important elements of the implementation of Tri Dharma
(Three Pillars of Higher Education), lectures need a means for scientific dissemination. On the
other hand, the managers of scientific journals in the field of communication science studies in
Indonesia incorporated in APJIKI (Association of Publishers Journal of Communication
Science Indonesia), seeks to manage the existence of the issue by maintaining the quantity and
quality of incoming scientific articles. The main problem in the process of review of scientific
articles is the authors' conformity with the style guide of scientific journal. The availability of
information regarding to the provisions of the writing of scientific journals provided on the
online page should be responded by the applicant's obedience during the preparation of a
scientific article. The influence between the two variables is tested by quantitative research
approach in positivism paradigm, based on the two dimensions of information availability from Mark Burgin (2010) and the six basic principles of Robert Cialdini (2004) about the writer's
concession in obeying the style guide of scientific journal. This study has been done to 42
respondents, who represent the editor of communication science journals in Indonesia. The
result of this research shows that there is a significant influence of the availability variable of
OJS style guide information towards the compliance of the writer of 13.10%, while the other
86.9% was influenced by other factors that can be used as a further research studies
