Published: August 2023

Chili is an important agricultural commodity in Indonesia and plays an significant role in the economic growth of the country. Its demand from households and industries reaches up to 61%. However, this high demand also means that monitoring efforts must be intensified, particularly for chili plant diseases that can greatly impact yields. If these diseases are not addressed promptly, they can lead to a decrease in production levels, which can negatively affect the economy. With technological advancements, automatic monitoring using image processing is now highly feasible, making monitoring more efficient and effective. Common chili plant diseases include chili leaf yellowing disease, chili leaf curling disease, cercospora leaf spots, and magnesium deficiency with symptoms that can be observed through the shape and color of the leaves. This research aims to classify chili plant diseases by comparing the CNN algorithm and the pre-trained MobileNetV2 based model performance using the Confussion Matrix. The study shows that the MobileNetV2 model, trained with a learning rate of 0.001, produces a more optimal model with an accuracy of 90% and based on the calculation of the confusion matrix, the average percentage values for recall, precision, and F1 score are 92%. These findings highlight the potential.

Published: August 2023

Modern wireless communication systems use orthogonal frequency division multiplexing (OFDM), a multi-carrier modulation method that resists multipath channels and provides bandwidth efficiency. OFDM is generally used with a Multiple-Input Multiple-Output (MIMO) system to boost diversity gain and channel capacity. MIMO-OFDM has several advantages, but its high PAPR value is a drawback. A non-linear high-power amplifier (HPA) can distort signals with high PAPR values. This issue can be resolved by employing predistortion, which compensates for nonlinear HPA. In addition to PD, channel coding can be used to improve the quality of systems with high PAPR values by adding redundant bits to the bits to be sent. In this paper, we report the experimental evaluations of the joint channel coding and pre-distortion (PD) technique on a 2x2 MIMO OFDM system using USRP hardware. The experiments are conducted in two scenarios: line-of-sight (LOS) and nonline-of-sight (NLOS) scenarios. The channel coding used in this scenario is convolutional code with code rates of 1/2, 2/3, and 3/4. From the results of the experiment, it can be seen that the system that uses PD combined with the convolution code produces better performance in the LOS and NLOS scenarios compared to the system without PD. In the LOS scenario, the use of PD can improve the SNR value of code rates 1/2, 2/3, and 3/4 by approximately 58.74%, 75.97%, and 96.20%. In the NLOS scenario, the use of PD can improve the SNR value of code rates 1/2, 2/3, and 3/4 by about 60.71%, 73.59%, and 71.84%. The measurement of the LOS scenario gives a better SNR value than the NLOS scenario, with a maximum SNR value of 30.86 dB, while the maximum SNR value of the NLOS scenario is 30.23 dB. This happened because the LOS scenario suffered minimal multipath fading compared to the NLOS scenario

Published: August 2023

The OVO application, despite having a large user base in Indonesia, has received low ratings compared to other digital wallet apps on the Google Play Store and App Store. Users frequently complain about the user experience, which greatly affects their overall satisfaction. This study evaluates the user experience and usability of the OVO application using the User Experience Questionnaire (UEQ) and System Usability Scale (SUS). The UEQ results show that efficiency is excellent (1.55), while attractiveness, perspicuity, dependability, and stimulation are above average (1.56, 1.67, 1.33, and 1.16, respectively). However, the novelty aspect falls below average (0.64), indicating a need for improvement. The SUS score is 77.53, classifying the application as "Acceptable" with a "C" grade and an overall "Good" rating. Addressing identified shortcomings can enhance user experience and usability, ultimately improving user satisfaction. This study contributes valuable empirical data to the field, offering insights for researchers and practitioners in assessing the user experience and usability of mobile applications.

Authors: Rizki Firdaus Mulya  , Ema Utami  , Dhani Ariatmanto
Published: August 2023

Acute lymphoblastic leukemia (ALL) is the most common form of leukemia that occurs in children. Detection of ALL through white blood cell image analysis can help with the prognosis and appropriate treatment. In this study, the author proposes an approach to classifying ALL based on white blood cell images using a convolutional neural network (CNN) model called InceptionV3. The dataset used in this research consists of white blood cell images collected from patients with ALL and healthy individuals. These images were obtained from The Cancer Imaging Archive (TCIA), which is a service that stores large-scale cancer medical images available to the public. During the evaluation phase, the author used training data evaluation metrics such as accuracy and loss to measure the model's performance. The research results show that the InceptionV3 model is capable of classifying white blood cell images with a high level of accuracy. This model achieves an average ALL recognition accuracy of 0.9896 with a loss of 0.031. The use of CNN models such as InceptionV3 in medical image analysis has the potential to improve the efficiency and precision of image-based disease diagnosis.

Published: August 2023

This work concerns an important sector in the field of radiation-matter interaction. We propose to contribute in this domain by studying irradiation phenomena induced by electron beams interaction with solid targets. These phenomena
are interesting since they could be implemented in several applications including surface characterization techniques and electronic spectroscopies. Our study was carried out by simulation using CASINO open source, which is based
on Monte Carlo methods. We considered different target materials namely: silicon (Si), zinc sulphide (ZnS) and Cu2ZnSnS4 (CZTS).We succeeded in predicting several physical phenomena for incident electrons of energies lower than
50 keV. In particular, we computed the primary and backscattered electron trajectories in the targets, the absorbed energies in interaction volumes and the energy of the transmitted electrons. The microanalysis of X-rays has also
been investigated.

Authors: Jumilah Jumilah , Wasis Wasis
Published: August 2023

The objective of this study is to create a misconception test instrument for identifying and understanding misconceptions in students regarding Bernoulli's Principle, particularly during hybrid learning. The validity and reliability of the test instrument are described in order to assess its effectiveness. Descriptive analysis techniques were employed to analyze the data. The findings revealed that the test instrument exhibits high validity (94.16%) and reliability (0.72%). On average, 34.9% of students were found to possess misconceptions regarding the sub-topic of Bernoulli's Principle. Item number 5 was identified as having the highest misconception rate (53%), specifically in relation to determining the speed of airflow above and below an aircraft's wings. These findings indicate that some students lack a comprehensive understanding of the fundamental concepts underlying Bernoulli's Principle, relying solely on its equations. Consequently, this research suggests that teachers can mitigate misconceptions and identify their causes by employing a four-tier diagnostic test, especially in the context of the sub-topic of Bernoulli's Principle

THE CONCEPT OF INTEGRATION OF RELIGION AND SCIENCE IN THE CONTEXT OF ISLAMIC EDUCATION
Authors: Ruswandi Agus , Natsir Nanat Fatah , Haryanti Erni
Published: August 2023

Religion and science are actually two things that cannot be separated. The dichotomy between general and religious sciences causes an imbalance between scientific aspects and ethical and moral aspects. Humans are not enough just to have intelligence in terms of intellectuality, but humans are required to have good spiritual aspects so that this becomes a balance so that there is no excessive fanaticism between religious knowledge and general science. Integration between science and religion is absolute because basically all knowledge comes from God. Religious science does not only talk about matters related to religious rituals, but also regulates social sciences, humanities, and science to understand everything that exists in this world. In the context of Islamic education, several concepts emerged to unite science and religion, including the concepts offered at the state and private Islamic religious universities with their characteristics. With the concept of integration, it is hoped that there will no longer be a dichotomy of thought that distinguishes or separates absolutely between religion and science

Azolla, the water fern grows luxuriantly in cooler periods and the optium temperature ranges from 25-30°C. Due to the hot summer preceding the kharif season rice raised in the Cauvery Delta Zone, raising Azolla as dual crop in rice is not in vogue. Among the Azolla species, A. microphylla adopted itself to this environment at Aduthurai. The biomass production was adequate in summer to provide supply of inoculum for the ensuing Kuruvai crop. Azolla production ranged from 42 g/m²/day to 164 g/m2/day with a 60 day mean production of 92 g/m²/day during April-June, 1990. Despite a water temperature of 42°C attained at 2 PM, A. microphylla established well.

Variability was induced in blackgram-cultivar T-9, through colchicine treatment of seeds and these colchicine induced mutant plants (colchiploids) were studied to find out the character association with yield through correlation and path coefficient analysis. This study clearly exhibited a certain positive correlation between plant height with stem girth, number of bunches per plant, number of pods per bunch and per plant and 100 seed weight. Further an interesting negative correlation between number of seeds per pod with grain yield was also reflected in this study and in addition the regression function indicated a high degree of influence on number of bunches per plant and the total number of days taken by the plant to flower on the expression of grain yield. The path analysis revealed that the total number of bunches per plant exerted the maximum direct effect on grain yield followed by the number of pods per plant, the total number of days taken by the plant for flowering and 100 seed weight.

Forty diverse genotypes of ragi were evaluated for the variability, heritability estimates and path co-efficient analysis of six quantitative traits. Close resemblence between GCV and PCV estimates for days to 50 per cent flowering and green fodder yield/plant, and high heritability indicated that selection for these traits would be much effective. The highest heritability and genetic advance in green fodder yield revealed predominance of additive gene effects. Green fodder yield/plant significantly and positively correlated with all the characters studied. Though leaf weight/plant had high influence of environment, it had the maximum positive direct and indirect effects through all other characters. Besides, days to 50 per cent flowering should be reckoned as an important trait in selection programmes.

A study with 12 crosses involving short duration rice varieties revealed the predominant role of dominance components over additive components for all the traits stuched, indicating the possibility of exploiting hybrid vigour. Additive X additive for ear bearing tillers per plant, grain number per car and 100-grain weight, additive X dominance for plant height and dominance X dominance for ear length and grain yield were the major components of genetic variance. For all the traits, the most common was the complementary type of epistasis. The crosses Co 41 X ADT 37 and IR 50 X ADT 37 were identified as promising to exploit both additive and additive X additive components in varietal improvement programme through the use of biparental mating in F2 generation.

Field experiment conducted at Coimbatore with maize in a typic ustropept soil revealed that application of phosphatic fertilizers irrespective of source, level and effects increased the available P. Among the sources, DAP and SSP were superior over RP and its combinations. The various sources and levels and the effects did not produce any significance in the P content of grain and stalk of maize. Significant difference among the sources for P uptake in grain was observed under cumulative effect whereas it was the direct effect for stalk uptake. The DAP and SSP proved significantly superior over RP and its combinations in the grain yield under direct and cumulative effects. However, the same trend was observed for residual and direct effects in the stalk yield.
