Testing an application is an important thing to do in software development. However, there are some tests that are sometimes missed after application development has been completed, such as performance testing. Performance testing is a type of test to ensure software will work properly under the expected workload. When performance testing is important to ensure that the functional needs of the system are running well. To ensure that the business objectives of the system are satisfactory and according to user needs can be done using Black Box Method. After ensuring the final results meet the specifications of the system needs, performance testing can be carried out. In performance testing, a load and stress testing methods are used to test the system, so as to be able to validate system performance are correct and determine the operating capacity of the system, with load limit at the break threshold and above the break threshold. This test is carried out to help determine how software can act well when accessed by several users together with a lot of data. This study conduct analyze the behavior of the system in the server environment that currently running and then optimize the configuration of the service and server to achieve concurrent users with 500 users at a time with jmeter as a performance test tools.

Information technology are developed very fast in the present days. Along with the development of time, the amount of data and users will also increase which results in process of accessed and process workload will become slower. The ability to provide fast retrieve information is highly demanded to be more efficient and effective at these time, hopefully no problems occur when the required data is to be access. To overcome this problem there are technologies called Cluster and Replication that can help ensure high service availability by utilizing several computer resources that work together. If thereâ€™s a server that experiences failure, the system will not be immediately disrupted because other servers will continue functioning and replace the task of main server. Cluster capabilities allow a database to stay alive for a long time. Replications are techniques to copy and distribute database and objects from one to another database and synchronise between them. And data consistency can be keepted. Testing results with clusters tend to be faster, and testing between double VMs and triple VMs looks superior to triple VMs so it can make new alternative of choice in implementing database programming

In the last 17 years, the usage of computer software, such as operating system software and application software, (after the appearance of Windows 95) have increased rapidly. This is shown by the increasing number of choices for user to use the software to facilitate their work, such as word processing software, digital image processing, and financial application. A software must have a good reliability. It means the software can work according to the needs of the user. In addition, the software can perform fast recovery when subjected to disruption caused by mistakes made by users of the application. Therefore, we need a method for determining the software reliability. The assessment is based on the observation of failures occur in a certain interval range. Based on the observation we will determine the specific characteristics of data that will be used to select the probability distribution to determine the value of reliability. The type of data is secondary data (discrete). This aims to conduct a preliminary assessment before they are applied in real cases. The determination of reliability is used to draw conclusions on observations. Cronbach's Alpha scale is used to see how well the conclusions are drawn.

One form of potential threat faced by Indonesia is an energy crisis that can disrupt national stability. However, the use of nuclear as an alternative source of clean energy through Nuclear Power Plants (PLTN) has not been realized until now. This research aims to identify the obstacles faced in the plan to build a nuclear power plant in Indonesia and explain the communication strategy in facing the rejection of nuclear energy utilization as a power plant in Indonesia. This research uses qualitative methods with data collection techniques through interviews with competent parties in the energy sector, especially nuclear energy and its utilization in power plants in Indonesia. The results showed that public acceptance of the nuclear power plant development plan experienced ups and downs depending on the time and events behind it. In addition, the interpretation of the phrase â€œconsidering nuclear as the last resortâ€ in the legislation is also one of the obstacles to the progress of the implementation of nuclear power plant construction. Therefore, the support of all stakeholders is needed for the initiative to revise the laws and regulations that are considered to hinder the construction of nuclear power plants, in addition to building communication with those who reject the development plan through structured and massive persuasive and educational methods.Salah satu bentuk potensi ancaman yang dihadapi Indonesia adalah krisis energi yang dapat mengganggu stabilitas nasional. Namun, pemanfaatan nuklir sebagai alternatif sumber energi bersih melalui Pembangkit Listrik Tenaga Nuklir (PLTN) belum terealisasi hingga saat ini. Penelitian ini bertujuan untuk mengidentifikasi kendala-kendala yang dihadapi dalam rencana pembangunan PLTN di Indonesia dan menjelaskan strategi komunikasi dalam menghadapi penolakan pemanfaatan energi nuklir sebagai pembangkit listrik di Indonesia. Penelitian ini menggunakan metode kualitatif dengan teknik pengumpulan data melalui wawancara dengan pihak-pihak yang berkompeten di bidang energi, khususnya energi nuklir dan pemanfaatannya pada pembangkit listrik di Indonesia. Hasil penelitian menunjukkan penerimaan publik terhadap rencana pembangunan PLTN mengalami pasang-surut bergantung waktu dan peristiwa yang melatarinya. Selain itu, interpretasi terhadap frasa â€œmempertimbangkan nuklir sebagai pilihan terakhirâ€ dalam peraturan perundang-undangan juga menjadi salah satu penghambat kemajuan implementasi pembangunan PLTN. Oleh karena itu, diperlukan dukungan seluruh stakeholder terhadap insiasi untuk merevisi peraturan perundang-undangan yang dinilai menghambat pembangunan PLTN, di samping membangun komunikasi terhadap pihak-pihak yang menolak rencana pembangunan tersebut melalui cara-cara persuasif dan edukasi yang terstruktur serta masif.

A College needs a good governance in implementation of information technology, especially which related with information security because information is an important asset. Framework which can be used for the preparation of information security governance is COBIT 5 from ISACA. The first Â step to start the preparation of the governance using COBIT is mapping between the goal of college with enterprise goals (EG), IT Related Goals and domain process COBIT 5. From 15 colleges that have been accredited in West Java (15 Januari 2015), produced 13 EG related for college accreditation A, B and 10 for college accreditation EG C. For a sample in process capability assessment of information security governance, we used Universitas Muhammadiyah Sukabumi (UMMI) as the research object, which is an accredited college C, and EG focused on optimization of business process functionality associated with the alignment of IT goals of IT and business strategy, and 10 processes, i.e EDM01, EDM01, APO01, APO02, APO03, APO05, APO07, APO08, BAI01, BAI02. From the results obtained capability assessment process UMMI value of 7 is on level 0, ie the value of the attribute <15-50% and 3 process closer to fulfillment level 1, ie the interval> 50-85%. Gap analysis results, it turns out that making such UMMI lack of work products (evidence / result) of activities of governance processes deemed to have been executed. To meet the achievement level, it is recommended to perform compliance on each best practice and work products, and can be initiated by creating a guide to information security.

This study investigates the efficiency of Network Function Virtualization (NFV) in managing network traffic using a simulation-based experimental approach. NFV offers flexibility, scalability, and cost-efficiency by replacing hardware-based functions with software-based services. The research involves the deployment of Virtual Network Functions (VNFs) such as firewalls, load balancers, and intrusion detection systems within a simulated environment using tools like Mininet, OpenStack, and GNS3. Performance was evaluated under varying traffic conditions—normal, moderate, and high load scenarios—by measuring latency, throughput, jitter, CPU, and memory usage. The findings indicate that while NFV performs comparably to traditional systems under low to moderate load, it suffers from performance degradation under high traffic, particularly in latency and resource utilization. However, the integration of intelligent orchestration and dynamic resource management can mitigate these limitations. The results suggest that with proper optimization, NFV can serve as a viable alternative to traditional network infrastructure, especially in supporting next-generation network applications. This study contributes to the understanding of NFV’s operational performance and provides recommendations for its deployment in modern networks.
