Abstract Testing the performance efficiency aspect was carried out to test the performance efficiency of the Unity 3D and Blender-based virtual laboratory media during the COVID-19 pandemic at the Electrical Engineering Vocational Laboratory. This test is carried out to test the performance of the media that has been created. The aspects tested are access speed, process speed, and simulation speed when run. Tests were conducted to measure processor and memory consumption through real time monitoring using MSI Afterburner. Divided into 2 stages of testing, namely time behavior and resource utilization. Time-behavior is focused on how long it takes the media or software to provide a response time to perform an action from a certain function. Resource-utilization is the degree to which software uses some resources when doing something under certain conditions.

Load Balancing Algorithm

Cloud load balancing is done to persist the services in the cloud environment along with quality of service (QoS) parameters. An efficient load balancing algorithm should be based on better optimization of these QoS parameters which results in efficient scheduling. Most of the load balancing algorithms which exist consider response time or resource utilization constraints but an efficient algorithm must consider both perspectives from the user side and cloud service provider side. This article presents a load balancing strategy that efficiently allocates tasks to virtualized resources to get maximum resource utilization in minimum response time. The proposed approach, join minimum loaded queue (JMLQ), is based on the existing join idle queue (JIQ) model that has been modified by replacing idle servers in the I-queues with servers having one task in execution list. The results of simulation in CloudSim verify that the proposed approach efficiently maximizes resource utilization by reducing the response time in comparison to its other variants.

The development of information and communication technology has penetrated various sectors, one of which is the education sector, especially in learning. The application of technology in the learning process is in the form of using virtual laboratory media to explain concepts that require a practicum, particularly in ab-stract materials. This study aims to determine students' metacognitive skills after applying the e-learning-based virtual laboratory media in physics experiment courses at the Department of Physics Education, Faculty of Teacher Training and Education, Universitas Papua. This qualitative research went through the stages of a lesson study. The data were collected from tests and questionnaires on stu-dents' metacognitive skills, observation sheets, interview guidelines, and video recordings during the open class. Further, the data were analyzed through Rasch modeling technique utilizing the Winstep application to analyze the students' met-acognitive activity questionnaire after learning. The lesson study encompassed three stages of a series of activities, namely Plan, Do, and See. In the Plan stage, discussions were held with the lecturer team to develop learning tools in the form of chapter designs, lesson plans, and learning media. In the Do stage, the model lecturer performed the learning process based on the media that had been estab-lished. In the See stage, the reflection was done to examine the learning imple-mentation carried out by the model lecturer in order to uncover weaknesses and strengths to be followed up on further learning. The results show that the quality of learning and students’ metacognitive skills at each meeting are improved. It is proven by the good and very good category of the aforementioned results. To sum up, e-learning based virtual laboratory media are able to improve learning quality and develop students' metacognitive skills in the physics experiment courses.

Cryptography is a branch of Computer-Science which fully devotes towards further enhancements or innovations of various applications concern to information security i.e., to manage Confidentiality/ Integrity of resources. Confidentiality of resources most probably look after by ‘Encryption–Decryption’ techniques like ‘DES,’ ‘AES,’ ‘Blowfish,’ ‘Two-Fish,’ etc., were as ‘Integrity’ managed by Hash Functions, which have a distinct paramount significance in Network-Security/Computer- Security/Internet-Security. Both the ‘Integrity’ of data and ‘Authenticity’ of resource proved with the help of digest generated by the Hash algorithm. There are several hash algorithms available to provide distinct security, depends on how hard is to break it and pre-defined resource utilization (time/space). Some well-known names are MD4, MD5, SHA, JH, Skein, Grøstl, Blake, Hamsi, Fugue, Crush, Whirlpool, Tav, etc. In this article, we are focusing on vulnerabilities in the Merkle- Damgard scheme for constructing Hash-Functions with suitable implementation of MD5.

The cloud datacenter has numerous hosts as well as application requests where resources are dynamic. The demands placed on the resource allocation are diverse. These factors could lead to load imbalances, which affect scheduling efficiency and resource utilization. A scheduling method called Dynamic Resource Allocation for Load Balancing (DRALB) is proposed. The proposed solution constitutes two steps: First, the load manager analyzes the resource requirements such as CPU, Memory, Energy and Bandwidth usage and allocates an appropriate number of VMs for each application. Second, the resource information is collected and updated where resources are sorted into four queues according to the loads of resources i.e. CPU intensive, Memory intensive, Energy intensive and Bandwidth intensive. We demonstarate that SLA-aware scheduling not only facilitates the cloud consumers by resources availability and improves throughput, response time etc. but also maximizes the cloud profits with less resource utilization and SLA (Service Level Agreement) violation penalties. This method is based on diversity of client’s applications and searching the optimal resources for the particular deployment. Experiments were carried out based on following parameters i.e. average response time; resource utilization, SLA violation rate and load balancing. The experimental results demonstrate that this method can reduce the wastage of resources and reduces the traffic upto 44.89% and 58.49% in the network.

The integration of information and communication technology in learning through the application of virtual laboratory media can be an alternative solution to overcome the constraints of time, cost, and laboratory safety in biology labs. Virtual laboratories are very suitable to be applied to the mechanism of evolution because they involve the context of space and time, and can provide opportunities for students to learn independently and increase active student involvement in learning. These study aims are to determine the effect of the application of virtual laboratory media on the understanding of student concepts; knowing increasing students' understanding of the concept of evolutionary mechanisms, and knowing students' responses after learning with virtual laboratories.This type of research is a pre-experimental design (nondesign) with one group pretest-posttest design. The research subjects were 37 students. The media used as many as 8 web-based virtual laboratory programs (online) that can be freely accessed. Data collection techniques include tests (pretest and posttest) and questionnaires. The pretest and posttest values were analyzed by the T-test while the questionnaire data were analyzed descriptively. The application of web-based virtual laboratory media on the evolution mechanism material influences the understanding of student concepts (t arithmetic> t table then H0 is rejected and H1 is accepted) The application of these media increases students' understanding of the concept of evolutionary mechanisms. The mean value increased from pretest 23.65 to 56.08 at the posttest with an increase of 32.43. Student responses to the application of media in learning showed 91.89% of students felt helped in understanding the process of evolution while 100% of students felt helped in understanding the role of evolution in causing evolution.
