Analisis Kekurangan Sistem: Sasaran, Batasan, dan Masalah Sistem

Summary

This video lecture from the University of Gorontalo's Informatics Engineering Department discusses critical aspects of system analysis and design, focusing on objectives, limitations, and issues within information systems. Key topics include performance improvement, cost reduction, and security in systems such as e-learning platforms. It also highlights challenges like slow server responses, ineffective communication, and security breaches. The lecture encourages students to evaluate systems through specific analytical questions to identify weaknesses. A case study on a whale shark tour booking app is used to demonstrate real-world applications of these principles.

Takeaways

• 😀 The main objective of an information system is to enhance performance, such as ensuring quick task uploads without frustrating delays.
• 😀 Information effectiveness is a critical goal, ensuring that data like class schedules and scholarship announcements are clear and timely.
• 😀 Reducing costs is a key objective, for example, by moving from paper-based systems to digital platforms to minimize administrative expenses.
• 😀 Security improvement is essential, such as protecting students' personal data (e.g., grades, email) from breaches through encryption and other measures.
• 😀 Increasing efficiency through intuitive user interfaces is another goal, helping to streamline processes like course registration and payment.
• 😀 Providing high-quality service is important, with helpdesk systems that are easy to access, responsive, and efficient in solving technical issues.
• 😀 System constraints include external factors like user access regulations, privacy policies, and infrastructure limitations (e.g., poor internet connection in remote areas).
• 😀 Identifying system problems requires asking specific analysis questions, such as whether the system improves performance, reduces costs, and ensures security.
• 😀 A case study on a whale shark tour booking app highlights how systems face challenges such as server overloads and security flaws during peak seasons.
• 😀 A practical approach to improving systems includes upgrading server capacity, using real-time synchronization APIs, and ensuring secure payment methods like SSL encryption and tokenization.
• 😀 Understanding system goals, constraints, and issues, while considering local conditions (like in Gorontalo), enables students to design robust and efficient information systems.

Q & A

What are the main objectives of a system, as discussed in the script?

The main objectives of a system are to improve performance, enhance information effectiveness, reduce costs, increase security, improve efficiency, and enhance service quality.

What is meant by 'system boundaries' in the context of this script?

System boundaries refer to the external conditions that govern how the application operates, such as user access regulations, campus privacy policies, and infrastructure limitations like network speed.

What are the six common objectives of a system mentioned in the script?

The six common objectives are: 1) Performance improvement, 2) Information effectiveness, 3) Cost reduction, 4) Increased security, 5) Efficiency improvement, and 6) Service quality improvement.

How can an e-learning system enhance performance according to the script?

An e-learning system can enhance performance by ensuring that tasks, like uploading assignments, are processed quickly, reducing server response times, which helps avoid user frustration.

Why is security a crucial objective for a system?

Security is important to protect personal data, such as student grades, IMs, and email addresses, from unauthorized access and breaches, ensuring the integrity and privacy of users' information.

What is an example of a system limitation given in the script?

An example of a system limitation is the slow internet connection in certain areas, such as Limboto or rural parts of Boalemo, which can hinder the performance of cloud-based applications.

How does the script suggest addressing issues with system performance?

The script suggests addressing performance issues by analyzing system speed, such as ensuring fast upload times for tasks in the e-learning system, especially during busy periods like quizzes or exams.

What kind of system problems are commonly encountered by users, according to the script?

Common system problems include slow system performance, ineffective information dissemination (like important announcements being lost in email), and security issues such as data breaches due to weak password protocols.

What is the role of the analysis questions listed in the script?

The analysis questions are designed to evaluate whether a system is meeting its objectives, such as improving performance, reducing costs, enhancing security, and improving efficiency.

How can a tour booking application for whale watching improve its system, based on the example in the script?

The tour booking application can improve by upgrading its servers to prevent overload, syncing information in real-time with a dedicated API, and implementing SSL encryption and tokenization for secure payments.
