The advancement of Industry 4.0 demands production systems to operate more efficiently, adaptively, and securely in facing global challenges. One promising technology that addresses these needs is the Digital Twin (DT), a digital representation of physical systems that enables integration between the real and virtual environments. Through DT, production processes can be modeled, monitored, and tested in real time, allowing for evaluation and optimization before implementation in actual systems. This study aims to explore the effectiveness of DT in modeling automated industrial systems, particularly in relation to improving production efficiency, quality control, energy savings, and operational safety. The research employed an experimental approach based on simulation within a robotic production line consisting of machines, sensors, actuators, and conveyors. The research stages included identifying system components and workflows, developing a DT model that integrates physical and virtual layers with Internet of Things–based data connectivity, and conducting simulations representing diverse operational scenarios. The findings indicate that DT implementation enhances operational efficiency, reduces production errors, and optimizes energy utilization. Furthermore, DT proves effective in strengthening safety aspects by enabling early detection of potential disruptions and providing preventive recommendations before significant impacts occur. Compared to conventional simulations, DT offers a more realistic, adaptive, and relevant approach to the needs of modern industry. The implications of this study highlight DT’s strong potential to become a new standard in the development and control of automation-based production systems, driving the creation of smarter, more efficient, and sustainable industries.

. Electrical energy is a primary need for every human being. Supercapacitors are sophisticated electrical energy storage devices that combine the advantages of conventional batteries and capacitors so that they have the ability to store energy better. The use of electrode materials is one of the factors that affect the effectiveness of supercapacitors, electrode materials can be made from polymeric materials, metal oxides, and porous materials such as activated carbon. Activated carbon is made through two main stages, namely the carbonization and activation stages. Bamboo charcoal is a solid product that uses bamboo raw materials through a carbonization process under high temperatures (high temperature charcoal). This research is a research using experimental method. From the research results, carbonized bamboo charcoal at temperatures of 300˚C, 350˚C, 400˚C, 450˚C and 500˚C has a higher electrical conductivity value as the carbonization temperature increases. So it can be concluded that the temperature in the carbonization process affects the electrical conductivity of bamboo charcoal.

This research was conducted at MAN 6 West Pasaman which was motivated by the lack of active learning of students in SKI subjects, where in the learning process the teacher only used conventional learning models. This makes students not interested in learning, they feel bored so that learning objectives have not been achieved optimally. This study aims to determine whether there is an influence of the Two Stay Two Stray cooperative learning model on student learning activity. This study uses a quantitative experimental approach with the type of quasi-experimental research (quasi-experimental). The data collection technique uses questionnaires and documentation. Data analysis starts from the normality test, homogeneity test and hypothesis testing. Based on the results of the analysis and discussion of the research data, the results of hypothesis testing were obtained using the Independent Sample Test, so the parametric statistical test results can be seen if sig (2-tailed) = 0.000 ≤0.05 then it is rejected and accepted. So that it can be concluded that there is an influence of the two stay two stray cooperative learning model on student learning activity at MAN 6 West Pasaman.

This study is important to carry out in order to add to the study of sharia banking and conventional banking, especially the scarcity of themes that discuss banking.

The problem in this study is the low activity and learning outcomes of students in IPS (Social Studies). This happens because the teaching method is only one-way, still using conventional methods, and students tend to be passive. The way to overcome this problem is through the use of Problem Based Learning (PBL), Group Investigation (GI), and Picture And Picture (PAP) models. The research aims to improve student activity and learning outcomes. This research focused on fifth grade students at SDN Teluk Tiram 2 Banjarmasin, which numbered 20 people, in the form of 12 boys and 8 girls. This research method applies a qualitative approach that uses the type of Classroom Action Research (CAR). Qualitative data were obtained from observations of educator and student activities, while quantitative data were obtained from individual written test results. The results of this study show that at the fourth meeting, the teacher's activity obtained a score of 26, rated as "Very Good". Student activity reached 100%, and learning outcomes met the success indicator (>81). In conclusion, PBL, GI, and PAP methods can make learning activities and results increase.

In this research, there were obstacles or problems with students' activities and learning outcomes in less than optimal science content. The reason is due to a lack of skills in gathering information, still using conventional approaches, and one-way learning. The proposed solution is to apply a combination model of PBL, TGT, and Picture and Picture. The purpose of this research was to determine the activities and learning outcomes of grade 5 students at SDN Teluk Tiram 2 Banjarmasin, of which there were 20 students, including 7 boys and 13 girls. This research applies the PTK method and also uses qualitative and quantitative approaches. Qualitative data was obtained from teacher and student observations, while quantitative data came from personal written tests to evaluate student learning outcomes. The research results showed that teacher activity at meeting 4 reached 94% with the criteria "very good". Meanwhile, student activity reached 90% and student learning outcomes had reached the success indicator, namely a score of ≥81. Thus, this combination of models can effectively overcome this problem.

The background of this research is that the model used by the teacher is not appropriate with the learning needs of students at MTsS Yati Kamang Mudik, the level of critical thinking of students seems less active in expressing opinions, not giving many suggestions or questions, not being able to explain problems, with the influence of the social environment. This research is a quantitative study. The research design used is Quasi-Experimental. The sample for this study was class VII students at MTsS Yati Kamang Mudik with a sample size of 40 students. The research samples were class VII-1 experimental using the Contextual Teaching and Learning model and class VII-2 control using the conventional model. Data analysis techniques used the Normality Test with the Kolmogorov Smirnov formula, and homogeneity test with Fisher's test followed by hypothesis testing with Independent t-test. The results of the study show that based on the results of data processing it can be concluded that there is a significant influence on the use of the Contextual Teaching and Learning (CTL) model as these results prove that the value of the experimental class Sig. (2-tailed) = 0.001. While the research alpha = 5% or 0.05. That is, the value of Sig. (2-tailed) is greater than the alpha value (0.001 <0.05) so that there is an influence of the Contextual Teaching and Learning (CTL) learning model on students' critical thinking skills in the Akidah Akhlak lesson at MTsSYati kamang Mudik in class VII.

Potential weaknesses faced by the company. So it is necessary to consider the aspects of process inefficiency, risk of work errors, delays in information, lack of transparency, high operational costs, vulnerability to data loss and difficulties in monitoring performance. In the current era of globalization and digitization, companies face pressure to increase operational efficiency and accountability in presenting financial information. By using the PALS (Pasticipatory Action Learning System) method, where this method basically involves accounting staff in the process of upgrading the Enterprise Service Bus (ESB) system from 30 accounting staff and 5 staff will be taken for the interview sample in this research. From the problems currently faced by companies in managing financial reports, they have not been able to carry out systematic recording. With better data integration using ESB, a company's various systems and applications can be connected and communicate well. In real-time reporting compared to manual (conventional) recording which requires processing time, ESB allows for better real-time financial reports.

This paper proposes a method based on the Lagrange optimization function and local search technique for minimizing the total cost of two power systems. The first system comprises ten multiple fuel thermal units (MFTUs) while the second system combines the first system with renewable energies, solar and wind power. The proposed method has advantages over its conventional method without a local search technique, called the conventional Lagrange function-based method (CLM), such as having the same parameters and exploiting other search spaces after getting convergence. The proposed method is more effective than CLM for the first system with the last case of load demand. In addition, the proposed method has better costs than previous algorithms, such as the Hierarchical numerical method (HNUM), Hopfield neural network, Adaptive Hopfield neural networks (AHNN) and modified Lagrange neural network (MLANN). Especially, the proposed method can find smaller costs than them, up to $6.78, corresponding to 1.4% for Case 1, and up to $2.43, corresponding to 0.4% for Case 4. Only the proposed method is tested on the second test system. The simulation results indicate that the method is very efficient for the problem with solar and wind energies and multiple fuel thermal units.

This research aims to analyze the problems and development of sharia banking in Indonesia in the context of globalization. Sharia banking in Indonesia has experienced significant development during the era of globalization. Globalization is a process of international integration that occurs due to the exchange of world views, products, thoughts and other cultural aspects. The progress of transportation and telecommunications infrastructure, including the emergence of the telegraph and the Internet, is a major factor in globalization which increasingly encourages interdependence of economic and cultural activities. The era of globalization has brought changes to the world economic order and presented challenges and opportunities for sharia banking. However, with the development of sharia banking, various problems and challenges have arisen that need to be overcome, the central problem is the lack of socialization and education to the community, as well as competition with conventional institutions which is also a challenge for sharia banking in Indonesia. The analysis method used by the author is a qualitative approach. The results of the research in this journal are the innovation of Islamic banking products, developing digital banking and increasing human resources as a strategy for the development of Islamic banking in Indonesia in the era of globalisation.    

Islamic financial institutions use an accounting system that is different from conventional accounting. The basis of sharia banking accounting follows the principles of Islamic economics which include the prohibition of interest or what is often called usury (including other usurious practices), then the prohibition of investment in businesses that are considered haram, as well as encouraging fair wealth and economic growth.

The Class IIA Women's Correctional Institution (LPP) in Malang City is included in a productive prison which is not only used as a place for fostering prisoners (inmates), but also used as a facility to accommodate the production of quality prisoner products. The WBP participates in productive program activities held by the prison, such as managing the soy sauce industry, handicrafts, convection business, salon business, making ecoprint batik, production of souvenir snacks. All WBPs are involved in these productive activities as a form of effort by the prison in organizing work guidance programs and skills education. The results of the activity show that the production of Malang City Class IIA Women's Prison can be said to be quite good and has selling value. However, it is unfortunate that marketing is done conventionally so that it has not achieved maximum product sales results. Therefore, it is necessary to have an evaluation that can be solved through the service activities carried out. This digital marketing practice activity with website development training can be a solution provided through this service. The activity can run smoothly because all prison officers are enthusiastic and conducive in participating in the training held. The hope of this activity is that they will be able to apply the marketing function optimally so that it can increase sales volume

Technological developments to date have had a rapid impact on all aspects of life, including economic aspects and aspects of government administration; many things have arisen and have had positive impacts, such as ease of access to information and simplification of services by the government. So that technology-based services can be prepared and implemented based on a policy that cannot be separated from the legal theory that binds it. In order to support ease of investment services, the Government has initiated an Online Single Submission (OSS) system since October 2017 as an implementation of Presidential Regulation Number 91 of 2017 concerning the Acceleration of Business Implementation and has conducted concept trials in three locations, namely: Purwakarta, Batam, and Palu. The design of this Information Technology-based system is basically by interconnecting and integrating the existing licensing service system at BKPM/Central PTSP (SPIPISE), a regional PTSP that uses the Ministry of Communication and Information's SiCantik system. In practice, the licensing implemented uses a one-door system, which makes it quicker for investors to process port permits. In this case, BP Batam provides services in the form of Indonesia Batam Online Single Submission or IBOSS. Licensing that previously used manual or conventional methods has switched to an electronic system connected directly to the national system. Port permits are now also handled directly by the BP Batam One-Stop Integrated Services (PTSP) Directorate, which impacts the speedy completion of port permit processing. However, in implementing technology-based services, it is essential to pay attention to regulatory or legal aspects so that implementation remains safe and does not cause material or non-material losses. To safeguard data, the application guarantees that the data recorded by Business Actors is only for Business Licensing services. However, even though there are guarantees or clauses, comprehensive research must still be carried out regarding technology-based services in order to support increased investment, considering that data security is an essential thing in running services.

In agriculture with the hydroponic method of the DFT system (Deep Flow Technique), the circulation of plant nutrients must occur continuously to prevent decay in plants. Along with the many concerns due to the large electricity costs incurred to run the irrigation system for hydroponic plants, the authors hereby design a tool in the form of a submersible pump as a medium for regulating the flow of water in plants by utilizing a 50 WP PV module instead of a source of electrical energy from PLN. The method used in this research is the method of observation, literature study, design, and testing. The results of the 50 WP solar panel-based submersible pump trial show that a circuit connected to a battery at 1M Head tends to produce a stable water discharge, which is an average of 6.03 liters/minute compared to one that is not connected to a battery, which is only 5.28 liters/minute. Furthermore, the resulting water discharge affects the quality of the plants, especially in root length, number of leaves, leaf length, and leaf size. The test results are used as a reference for the comparison of expenditure costs between irrigation systems run using solar cells and those based on conventional (PLN).
