Contribution of Islamic Management In Building Ethics In Organizations
Ethical misconduct and business scandals caused millions of dollars in losses, left behind damaged organizations, forced them to close their business and left thousands employees jobless without any future guarantee or security. This incident has left scholars and managers asking what role they might have played to curb these ethical scandals and what role they can play in the solutions. Scholar and managers collectively have responded to the ethical challenges that we face in organizational life. Some scholarship assesses the current state of ethics in management education, helping us to diagnose and tackle the realities of unethical behavior. Part of the solution to this problem is to design and develop courses and programs in a better way, integrate business and management learning with ethical conduct. Scholars should focus on which standards should be advanced. Indeed, what connects these diverse discussion is a clear recognition that educational components designed to solve the ethical quandaries we face will require a multifaceted and comprehensive approach. Religions and philosophical schools of thought have always played a significant role in the development of human values and behavior which has a great impact to business and corporate management. Research also suggests that the encouragement of religious principles in business can lead to benefits in the areas of creativity, honesty and trust, personal fulfillment, and commitment, which will ultimately lead to increased corporate and business performance. It is where Islamic Management come into place where the foundations, principles, and practices will give impact in developing ethical standard to organizations. Islamic Management will bring students and managers back to basic where they cannot put aside the role of religion in safeguarding management practices in organization.

Inflation Forecasting In East Java Using Autoregressive Integrated Moving Average Method
Inflation is an economic event that often occurs even though it is not wanted. Based on data from Badan Pusat Statistik in 2015-2020 inflation in East Java was 3.08%, 2.74%, 4.04%, 2.86%, 2.12%, 1.44%. From these data, it can be seen that inflation data is fluctuating. Therefore it is necessary to control inflation because high and unstable inflation can have a negative impact on the socio-economic conditions of the community. In addition, it also makes it difficult for the government to determine future policies. Seeing the importance of controlling inflation, it is necessary to study to predict the inflation rate in the future. One of the studies/methods to predict that is often used is the Autoregressive Integrated Moving Average (ARIMA) method or also known as the Box-Jenkins method. The ARIMA method is a method that is easy to use because it is flexible in following existing data patterns and has high accuracy and tends to have a small error value because of the detailed process. From the analysis results, the best ARIMA (p,d,q) model is the ARIMA model (2,1,1) with an AIC value of 76.77. The results of forecasting with the ARIMA model (2,1,1) respectively are 0.2593698, 0.1892990, 0.1340639, 0.1368309, 0.1572021, 0.1642381, 0.1598897, 0.1557251, 0.1556074, 0.1570151, 0.1576092, 0.1573511, 0.1570423, and 0.1570111.

Framing Behaviorist Theory toward Situational Language Teaching (SLT)
The changing of foreign language teaching methodology happens over the years due to the shift of the changes of language teaching’s goals in different periods and in different places regarding the nature of language and the nature of learning. The aims of the paper are contextualizing behaviorist theory for Situational language teaching (SLT) and its relevance in current language teaching from practical experiences. The paper follows a narrative approach to review the previous works of literature on behaviorist theory, SLT, and its implementation. The findings are behaviorist theory becomes the fundamental learning theory of SLT that flourishes in SLT’s teaching and learning activities in the classroom. Influenced by behaviorist theory, SLT becomes a teaching method that provides more guided repetition and substantive activities. In addition, along with the existence of the trend of communicative language teaching and scientific approach, SLT is still implemented by teachers for various education levels to achieve teaching objectives. In conclusion, unfashionable methods do not mean that they are not able to apply in current teaching practice. Some modification activities can be created to attain meaningful learning. Therefore, it is suggested that in applying certain methods in teaching practice, practitioners or teachers should consider the following question: who the learners are, what their current level of language proficiency is, what their goals want to be achieved through learning activities, what sort of communicative need they have, and so forth.

Disease Detection System in Tobacco Leaves based on Edge Detection with Decision Tree Classification Method
Indonesia has long been known as an agricultural country, one of Indonesia's best agricultural products is tobacco. Tobacco with good quality can be seen from the leaves, in fact the diseases that attack tobacco are of various types which can be seen from the changes in the tobacco leaves starting from the seeding and planting period. In the tobacco growing period, it is divided into two major parts, namely seeding period and the planting period, so that diseases that attack tobacco are also divided into two, namely diseases that attack during seeding and planting. This research is limited to diseases that attack tobacco at the time of planting, because at the time of seedling the tobacco has not yet produced leaves. When tobacco enters the planting period, at this time tobacco leaves begin to form. Good care is needed at this time such as fertilization, nutrition, vitamins, and pest control in order to obtain healthy tobacco so that tobacco is not susceptible to disease. Tobacco that lacks nutritional intake will be susceptible to diseases including fungi, bacteria, and viruses. The disease attack on tobacco has its own characteristics that appear on tobacco leaves. Early detection of the disease is very important so that disease control can be precise and the spread of the disease can be prevented so as not to cause endemic. In this research, an early detection system of tobacco leaf disease based on image processing will be designed. Normalization image, grayscale technique, folllowed by edge detection will be applied in these image so that from here the entropy, energy, and inertia values of the image can be obtained using statistical measures, and the last one using the decision tree classification technique can be classified as uninfected leaf or infected leaf. In this study, feature extraction from images of tobacco leaves that are not infected with the virus using grayscale techniques followed by edge detection produces an average statistical measure with entropy (h) values between 2,341 to 2,676, energy (e) values between 6,112 to 6,665, and inertia values. (i) between 3,322 to 3,576, while for leaves infected with the virus the average value of entropy (h) is between 4,543 to 5,576, the average value of energy (e) is between 12,212 to 13,455, and the average value of inertia (i) between 5,343 to 6,597.

Classification of Lung CT-Scan Images for Covid-19 Detection Using Texture Feature Extraction and Naive Bayes Algorithm
Covid-19 diagnostic testing is divided into 2 approaches, namely laboratory-based approaches such as Swab Tests, PCR Tests, and Rapid Tests. To minimize transmission, a second approach is used, namely a non-laboratory approach that uses imaging diagnostic tools such as x-rays and Computed Tomography (CT). It is hoped that the use of this non-laboratory approach can be an alternative for detecting the Covid-19 virus and will also minimize the spread of the covid virus because at the time the diagnosis process takes place there is little direct contact with patients. Chest CT scan has a high sensitivity for diagnosing Covid-19. A CT scan uses the transmission of x-rays through the patient's chest, which is then processed with high-resolution medical images. In this study, the classification of Covid-19 images through CT-Scan images of the lungs using texture feature extraction and the naive Bayes classifier algorithm is a system that enters information in the form of input images and compares them with images in the database. The data set used is 200 CT-Scan images of Covid-19 lungs and 200 CT-Scan images of Non-Covid-19 lungs. The training data uses 150 Covid-19 images and 150 Non-Covid-19 images, while the rest is used as test data. The first method used is feature extraction, namely mean intensity, standard deviation, skewness, energy, entropy, and smoothness. After successfully obtaining the feature, it is calculated using the Naive Bayes classifier algorithm. The results obtained from this study get an Accuracy rate of 54%, Precision of 55.88%.

A magnetic field is defined as the space around a magnet that is still experiencing a magnetic force. As the electric force, the magnetic force is driven by something, namely a magnetic field. A moving charge creates a magnetic field which in turn exerts a force on another moving charge. This study aims to determine the effect of magnetic fields exposure on the growth of spinach plants. The increase in demand for spinach in Indonesia has not been matched by the availability of sufficient spinach, one of the reasons for the insufficient availability of spinach is the decrease in fertile land for agriculture. This causes the ability to produce spinach planted in the ground also decreases. This study uses materials that are easily obtained, the method used in this research is quantitative research with a true experimental design, in the form of magnetic field exposure on the growth rate of spinach plants. The magnetic field used is produced from the coils of copper wire with the number of 5, 20, 35, 50 and 0 widing, with the duration of exposure was 30 minutes every day for 7 days. Magnetic fields in water exposed whare soaking spinach seeds rested which increases the permeability of the seed film, activates calcium ions, and inhibits the growth of microorganisms in water that are harmful to seed germination and plant growth. From the results of this study indicate that the use of copper wire with the number of widing is still not optimally used.

Local Wisdom-Based Science Learning Model In Indonesia (Meta-Analysis)
This paper aims to summarize the research findings related to local wisdom-based science learning in Indonesia from 2013 to 2022. In order to get insight into the knowledge of the local wisdom-based science learning model in Indonesia; So, the researcher decided to present this paper on several points. They are the objective of the learning model, research methodology, the data collection instruments, and also the sample investigated. Besides, several learning models such as field trips, inquiry, PBL, PjBL, ELSII, and 7E are also presented in this paper. The research finding shows that PBL gives more contribution (85,8%) to the development of the science learning model. Further, local wisdom-based science learning can be developed by producing learning modules, worksheets, and lesson plans, and also can be incorporated into the assessment and remedial process. Additionally, the development of local wisdom-based science learning has several objectives to help students’ independent learning, increase students’ learning results, develop students’ character and problem-solving skills, increase students’ social constructive relationships, and group work, and also improve students’ knowledge about local culture.

Family Functioning Against Problem Solving Coping Adolescent Victims of Bullying
Bullying generally has a negative impact on the victim's mentality. Victims of bullying have a negative impact on themselves and the environment if not addressed immediately. Family functioning is one of the factors that can minimize the occurrence of bullying. Through problem solving coping, children imitate what parents usually do in solving a problem. This research uses descriptive qualitative methods, using interviews and observations as data collection techniques. The results of this study indicate that problem solving in the family plays an important role in family functioning, along with the selection of coping strategies used in solving a problem. Coping strategies used by a child are innate constructs from parents and tend to be stable over time.

Dynamical Analysis of Ratio-dependent Predator-Prey Models with Prey Refuge and Optimal Harvesting on Both Populations
In this article, we discuss a dynamical analysis of ratio-dependent response predator-prey model with prey refuge and harvesting on both populations. Harvesting on predator and prey is used because both populations are assumed to have an economic value. In this model, it is also assumed that prey has an instinct to protect themselves from the threat of predators. The conducted dynamical analysis consists of determination of equilibria, existence conditions and their stability. Analytical results show that there are two equilibria: namely predator extinction point and the coexistence point which are exist and stable under certain condition. Furthermore, Pontryagin maximum principle is used to find optimal harvesting on predator and prey. Some numerical simulations are performed to illustrate the analytical result.
