The potential of JAKABA (eternal fortune fungus) from rice washing water as a liquid biofertilizer for pre-planting soil of mung bean (Vigna radiata L.)
No full textMung bean (Vigna radiata L.) is a legume crop with high economic value, containing 20-25% protein and rich in vitamins and minerals. Despite its agronomic advantages, its productivity in Indonesia remains low. The quality of planting media and proper nutrient management significantly affect productivity. The use of inorganic fertilizers can negatively impact soil, necessitating alternatives such as liquid biofertilizers. One potential type of liquid biofertilizer is JAKABA, a fungal culture derived from fermented rice washing water. This study aims to determine the effect of JAKABA as a pre-planting liquid biofertilizer on the growth of mung bean plants. The experiment employed a Completely Randomized Design (CRD) with four treatments: P0 (control), P1 (JAKABA 1:5 water), P2 (JAKABA 1:10), and P3 (JAKABA 1:15 water), each replicated four times. The experimental procedure included JAKABA production, mung bean seeding, and watering for seven days. Measured parameters included plant height, stem diameter, number of leaves, leaf length, and leaf width. Data analysis used One Way ANOVA test, followed by Duncan's test at α=5% significance level if significant differences were found. Results showed that the application of JAKABA as a pre-planting liquid biofertilizer had a significant effect on mung bean growth. Application of JAKABA liquid biofertilizer in pre-planting soil significantly enhanced mung bean vegetative growth. The 1:5 water dilution optimally increased plant height (26.35±0.64 cm), stem diameter (0.22±0.05 cm), and leaf count (0.22±0.05), while the 1:15 dilution maximized leaf dimensions (length: 4.12±0.29 cm; width: 3.02±0.38 cm). To conclude, the use of JAKABA as a pre-planting liquid biofertilizer effectively enhancing the vegetative growth of mung bean plants, with varying effectiveness depending on the concentration and observed growth parameters

ABSTRACT
The deterioration in rice seed (Oryza sativa L.) viability during
storage is a serious problem in rice cultivation caused by various
factors, including cell membrane damage and increased
production of reactive oxygen species (ROS). ELF (Extremely Low
Frequency) magnetic fields offer an environmentally friendly
solution to improve seed viability through mechanisms of cellular
response activation and membrane integrity repair. Magnetic
fields can induce changes in electron flow in cells, potentially
accelerating metabolic processes and enhancing plant growth.
This research aims to analyze the effects of ELF magnetic field
induction on aged rice seed (Oryza sativa L.) viability. This
research used a Completely Randomized Design with four
exposure time treatments: control (M0), 3 minutes 54 seconds
(M1), 7 minutes 48 seconds (M2), and 11 minutes 42 seconds (M3),
replicated four times, resulting in 16 experimental units. The
samples used were 8-month-old Inpari 32 HDB rice variety seeds,
with a total of 800 seeds. Data analysis used One Way ANOVA and
Duncan Multiple Range Test (DMRT) with a significance level of
α=5%. Results showed that ELF magnetic field exposure
significantly affected aged rice seed viability. Treatments M2 and
M3 showed optimal results in several parameters, including
normal germination percentage (98.00% and 97.50%), mean
germination time (2.47 days), and germination index (268.75). The
magnetic field also increased radicle length (6.95 cm) and plumule
length (4.82 cm). Although it did not significantly affect the
germination time range and seed growth uniformity, the uniformity
value showed improvement (51.50-60.50%). These results indicate
the potential use of ELF magnetic fields to improve aged rice seed
viability.

Studi Kritis Terhadap Pemahaman Fahmi Basya Terkait Dengan Ayat-Ayat Negeri Saba
No full textCriticism is something that must be built in the scientific world. Because, in science there is no such thing as a definite truth. Criticism here to bring it in the right direction. Especially about the story of the past contained in the Qur\u27an. A story that is explained in it contains truth, lessons and teachings evidently undeniable for all creatures of Allah, for the happiness of the world and the hereafter. This study uses qualitative research in the form of library research, the author uses the approach of the theory of the Qur\u27an and Interpretation and the theory of Diltheiy thinking and interpretive writing ideas in Indonesia. Meanwhile, the collection of data by means of documentation, namely the book Indonesia Negeri Saba\u27by Fahmi Basya and also taken from various related sources. Furthermore, the analysis is done by reading and examining Fahmi Basya\u27s understanding writing, which is written in his book. In summary, Fahmi Basya confirmed 14 comparative accounts of Indonesia and Yemen based on the Qur\u27an and 53 scientific facts which he discovered that Indonesia was the State of Saba\u27. Fahmi Basya\u27s understanding is very contrary to the commentators at least caused by two problems. Finally, Fahmi Basya wants to prove that the State of Saba \u27in the Qur\u27an in Indonesia. Based on the study of Fahmi Basya\u27s understanding it was found that Fahmi Basya was not an expert in the field of the Qur\u27an and Tafsir. So, when he understands the Qur\u27an and reveals the results of his research in the community it needs to be reviewed. Seeing with the scientific viewpoints of the Qur\u27an, Fahmi Basya\u27s interpretation seems to match his discoveries with the Qur\u27anic Verses. And forcing all that can be matched look for verses of the Qur\u27an

Construction of the Phylogenetic Tree from Genus of Carnivorous Plants Based on Internal Transcribed Spacer (ITS) Marker in Silico
No full textCarnivorous plants are plants that have morphological adaptations to prey on and digest small animals as an additional source of nutrition. There are several genera of carnivorous plants, namely Nepenthes, Drosera, Heliamphora, and Pinguicula. Among these genera, they have similar morphological and molecular characteristics and uniqueness. Molecular characterization needs to be carried out to analyze the genetic relationships between carnivorous plant species through the construction of phylogenetic trees. This study aims to obtain information on genetic relationships in several genera of carnivorous plants using an in silico phylogenetic tree based on Internal Transcribed Spacer (ITS) sequences. ITS sequences were collected from NCBI by searching for species names and then aligned using Clustal-W. Subsequently, the construction of the phylogenetic tree was performed using MEGA X with the Maximum Likelihood method and Bootstrap analysis of 1000. The results of the phylogenetic construction of several carnivorous plant genera are divided into two main clades. Clade I is divided into sub-clades: clade IA consists of species from the genera Heliamphora and Drosera with a bootstrap value of 76, while clade IB consists of species from the genus Pinguicula and one species from Nepenthes with a bootstrap value of 56. Clade II consists of species from the genus Nepenthes with a bootstrap value of 52. The results of this phylogenetic construction show the grouping of carnivorous plant species based on genetic similarity

Application of fuzzy cognitive map in simulating strategic information system planning process / Ahmad Fahmi Abu Hassan
No full textIn this day and age, more researches have been conducted in the domain of Strategic
Information System Planning (SISP). However, this is just the continuation from the
1980's where various articles began to probe the underlying causes for the relationship
between Information Technology (IT) and businesses. Since then, many academicians
and theoreticians have come out with models and approaches to analyze the use of IT
from a strategic point of view. Reflect to that, this research is to show the application
and capabilities of Fuzzy Cognitive Map (FCM) in simulating SISP business scenarios.
This research was conducted because of the level of infancy held by FCM in the SISP
domain. Moreover, SISP environment frequently deals with uncertainties and the "whati
f circumstances. So, rather than practicing other SISP tools such as Boston Consulting
Group (BCG) Matrix, Porter's Five Forces Model and Generic Business Strategies, this
research is intended to use FCM as the technique in formulating SISP strategies. In
order to achieve the objective, two SISP business scenarios have been designed using
FCM technique before being simulated in an open-source simulation program. The
simulation program has been developed by its author and using Java programming
language. From the simulation, its ou^ut and results have been analyzed and discussed.
For the first scenario, it is found that FCM did not provide enough information in
decision making for SISP. However, the second scenario showed some promising
feature by providing meaningful and interpretable output that can offer broader view for
managers in formulating SISP. As recommendations, future researchers should run the
simulation on other programs, simulate more SISP scenarios and should also be able to
propose a more intricate and extended FCM
