Abstract

Food prices have an important role in maintaining economic stability and public welfare, as price fluctuations can have a direct impact on purchasing power and inflation. The manual process of recording and reporting food price data at the Department of Agriculture and Food Security of Palu City leads to inefficiencies, data inaccuracies, and difficulties in tracking historical information. These limitations highlight the need for a structured system that can support accurate and efficient data management. This study applies a prototyping method to develop a web-based information system tailored to the needs of the institution. The development process involves continuous interaction between users and developers to ensure the system meets practical requirements. Data were collected through interviews, observations, and documentation. System functionality was tested using black box testing, while usability was assessed using the System Usability Scale (SUS) questionnaire. The results indicate that the system's features, including daily price input, automatic average calculations, report submission, and approval workflows, function correctly. Users are able to interact with the system efficiently, and the SUS results show that the system falls into the acceptable usability category, indicating that it is easy to use. In conclusion, the development of this web-based information system improves the efficiency and accuracy of food price data processing and reporting. It provides a reliable tool for managing information within the department and supports better operational performance.

Abstract

The internet as a form of technological advancement continues to develop every year and has a great influence on human activities, including in terms of sales. The Jepun Bali Store, which sells products typical of Hinduism and Balinese customs, markets its products online with Instagram, Facebook, and WhatsApp. Instagram and Facebook are used to display the catalog, while WhatsApp is used for order communication. However, this system is considered less efficient because customers have to switch applications to view products, ask questions, and order. Stock and price information is not available in real-time, and the ordering process is still done manually, making it difficult for customers. From the manager's side, manual order recording risks creating errors, while admins are often overwhelmed with handling queries across multiple platforms, which impacts customer satisfaction. This research aims to simplify the transaction process, speed up services, and increase efficiency by applying the Design Thinking method. This method helps in understanding the needs of the user, structuring problems, and producing solutions through systematic stages. The results of the design test using the System Usability Scale (SUS) method with 30 respondents obtained a score of 88.5833 out of 100, included in category A (Excellent) and considered acceptable.

Abstract

Office 365 is an online learning method that is considered appropriate to be implemented in both partner schools as an additional method to conventional methods. The e-learning method is an electronic learning system that utilizes the internet in its process, allowing teachers to interact with students in online classrooms. SMPN 5 Palu in Central Sulawesi Province is one of the junior high schools strategically located, accessible from three directions with smooth transportation. This school has several strengths, including: highly committed teachers dedicated to improving the quality of graduates, a large number of applicants, high student motivation, and adequate laboratories, including a multimedia laboratory. The teaching methods used by teachers at the partner school have been conventional, such as lectures in the classroom, with no utilization of internet resources in their teaching, as they are unaware of their potential. However, the facilities and infrastructure available to teachers and students are highly supportive, as most teachers and students already have their own laptops, and the school has computer laboratory facilities. Similarly, telecommunications and internet networks now cover almost all areas of Palu City, making it easy to implement online learning. The aim of this training is to enable learning to proceed effectively even under PJJ conditions by adapting to Microsoft Office 365 so that students who are far outside Palu City can still carry out online learning. Assisting teachers in managing online classes, such as uploading materials, creating online practice questions and assigning weights to those questions, creating engaging educational videos from materials, and so on. Microsoft Office 365 is a cloud-based Office application developed by Microsoft that allows users to access various content online via the internet. The development of digital classrooms based on Microsoft 365 has recently been trained to 30 teachers at SMP N 5 Palu.

Abstract

Admission of New Students (PPDB) is one of the crucial stages or processes in the world of education, including at the Kindergarten level. A PPDB process that focuses on effective user experience is very important to maintain the reputation of educational institutions and provide a positive experience to parents of prospective students. The Al Qolam IT Kindergarten PPDB process is still carried out manually or conventionally, so it takes quite a long time for parents to process the registration form and return the registration form to the data processing process by the school operator. Considering these problems, designing the PPDB business process with a focus on user experience using BPMN (Business Process Model and Notation), it is hoped that this will create a simpler, more comfortable and intuitive registration experience for parents of prospective students and accuracy in data processing.

Abstract

Background: A few people prefer to consume medicinal plants compared to modern medicine. This is because modern medicine contains chemicals which over time can have a bad impact on the kidneys, and medicinal plants are also considered cheap treatments. Meanwhile, in our current environment, there are plants that grow and have certain benefits, but some people don't know whether these plants are herbal medicinal plants or not. By utilizing technology, people can find out about herbal medicinal plants based on the leaves by photographing them on an Android smartphone. Method: The method used to extract features from the leaf image is Scale Invariant Feature Transform (SIFT). Aim: This research aims to recognize leaves whose images have been photographed or uploaded. The system will identify herbal medicinal plants using the leaf image of the plant using the Scale Invariant Features Transform (SIFT) method. Result: Feature Extraction and Support Vector Machine (SVM). With this system, it is hoped that users will be able to identify herbal medicinal plants that may grow in the surrounding environment. Based on the description in the background above, the problem formulation in this research is how to identify herbal medicinal plants using leaf images using Android-based SIFT feature extraction. Conclusion: The results of the confusion matrix test explain that this system has an average accuracy of 77%, which means that this system is quite good at identifying leaf images, even though the error rate is quite high at 23%.Keywords—Medicinal Plant Leafs, SVM, SIFT

Abstract

Abstrak: Melakukan permainan satu sama lain, berinteraksi dengan media pembelajaran, baik itu media display atau pun media realia yang sangat menyenangkan. Di sepanjang jendela dalam kelas atau pun di sudut-sudut kelas, terpasang aneka poster, foto para pahlawan, dan model 3 dimensi yang berbentuk hewan atau pun tumbuhan, ataupun poster yang berisi aritmatika sederhana. Seiring dengan perkembangan zaman, ada beberapa kekurangan dalam media pembelajaran yang dianut secara turun temurun ini. Salah satunya adalah bahwa media pembelajaran itu dapat patah disalah satu bagiannya, atau pun tampak kusam karena jarang dirawat. Hal lain yang mendasari peniliti untuk melakukan riset untuk membangun aplikasi ini adalah adanya pandangan anak didik bahwa mempelajari mata pelajaran matematika itu cukup rumit dikarenakan kesulitan dalam memahami konsep dasarnya. Kemungkinan lain yang dihadapi adalah kurang improvisasinya para guru dalam menyajikan algoritma sederhana atas proses aritmatika sehingga daya nalar dan daya pikir anak didik menjadi berat. Produk yang dibangun dapat menampilkan proses aritmatika sederhana yang cukup interaktif dengan cara yang unik dan menyenangkan. Dimana aplikasi ini dirancang berbasis Augmented Reality yang memberikan tampilan seolah-olah angka tersebut nyata, sebagaimana sering dikenal dengan model 3 dimensi. Siswa tersebut hanya mendekatkan barkode yang telah disediakan didalamnya telah dilengkapi dengan angka-angka dan operator tambah, bagi, kali, kurang dan lain sebagainya. Abstract: Playing games with each other, interacting with instructional media, be it display media or real media fun. Along the window in the classroom or in the corners of the class, there are various posters, photographs of heroes, and 3-dimensional models in the form of animals or plants, or posters containing simple arithmetic. Along with the development of the times, there are some shortcomings in the learning media adopted from generation to generation. One of them is that the learning media can be broken in one part, or looks dull because it is rarely treated. Another thing that underlies the researcher to do research to build this application is the view of students that learning mathematics course is quite complicated due to difficulties in understanding the basic concept. Another possibility faced is the lack of improvisation of teachers in presenting a simple algorithm on the process of arithmetic so that the power of reasoning and thinking power of the students become heavy. Built-in products can feature simple interactive arithmetic processes in a unique and fun way. Where this application is designed based Augmented Reality that gives the appearance as if the number is real, as is often known as 3 dimensional model. Students are just closer barcode that has been provided in it has been equipped with numbers and operators such as, added, mines, multiple, and so forth.

Abstract

Consensus mechanisms play a crucial role in determining the efficiency and scalability of blockchain systems. The two most commonly used algorithms are Proof of Work and Proof of Stake, each exhibiting distinct performance characteristics under high transaction loads. This study aims to evaluate and compare the performance of both consensus mechanisms through a simulation-based experimental approach. Testing was conducted using the Hardhat framework in a local environment under two primary scenarios: transaction scaling and burst transaction.Four evaluation metrics were employed: throughput, transaction latency, finality time, and mempool congestion. The results indicate that Proof of Stake consistently outperforms across all four metrics, demonstrating high throughput, stable latency and finality time, and controlled mempool congestion. In contrast, Proof of Work shows a significant decline in performance under heavy load due to its static and non-adaptive mining process.The Mann-Whitney U statistical test confirms that the performance differences are statistically significant across nearly all metrics. This research provides deeper insights into the strengths and limitations of each consensus mechanism under high-load conditions using Hardhat, and contributes to a broader understanding of blockchain scalability in real-world applications. The findings suggest that Proof of Stake is more suitable for large-scale blockchain implementations that demand high efficiency and speed.

Abstract

The manual meeting scheduling process has a high potential for scheduling conflicts. These conflicts include delays in information, meeting room clashes, or meeting time clashes. These problems are caused by the absence of a system and visualization for managing meeting schedules. To streamline the scheduling process, a website-based meeting scheduling information system was developed for activities that are carried out routinely with high frequency, using a combination of two algorithms that can overcome these problems. The Greedy algorithm is used to detect conflicts, and the rule-based Decision Tree algorithm is used to provide alternative time or room suggestions when schedule conflicts occur. The results of blackbox testing and usability testing prove that the application of these algorithms makes the system more effective and provides the right workflow for this system. This research contributes to the development of an effective meeting scheduling system and integrates two algorithms as a new solution in managing the scheduling process.
