Abstract

In Indonesia, the type of cancer that contributes to the highest death rate is breast cancer, so there is a great need for early examination, clinical examination, and screening, which includes mammography. Mammography is currently the most effective method for detecting early-stage breast cancer. This study aims to classify breast cancer cells based on mammogram images. The method used in this research is CNN (Convolutional Neural Network) with the NASNet Mobile model for classifying three classes: normal, benign, and malignant. The CNN method can learn various input attributes powerfully so that CNN can obtain more detailed data characteristics and has better detection capabilities. This research obtained the most optimal model based on the percentage of accuracy, sensitivity, and specificity values of 99.67%, 98.78%, and 99.35%, respectively. This research can be used to help radiologists as considerations in making breast cancer diagnosis decisions.

Abstract

The high crime rate will create unrest and losses for the community. One of the provinces with high crime rates is East Java. This study aims to analyze the factors that influence criminality in East Java to ensure appropriate crime prevention and control measures can be taken. The factors that potentially influence crime in East Java studied include population density, the number of poor people, unemployment, Human Development Index (HDI), Gross Regional Domestic Product (GRDP), and per Capita Expenditure, which are associated with geographical conditions in each region (regency/city) collected from BPS East Java in 2022. Meanwhile, the number of crimes is collected from the East Java Regional Police. This research uses a statistical method, namely the Spatial Durbin Model (SDM), which is a particular form of the Spatial Autoregressive Model (SAR) method with Queen Contiguity weighting by analyzing geographically (spatial processes). Based on the results of the analysis, it was found that the influential factors were unemployment, HDI, GRDP, and per Capita Expenditure, and the R-square result was obtained at 85.18%. This shows a relationship between spatial accessibility and crime, where unemployment, HDI, GRDP, and per Capita Expenditure in an area can affect regional vulnerability to crime

Abstract

Peningkatan pengalaman pengguna (User Experience) pada website audit checklist PT XYZ dilakukan dengan menerapkan metode User Centered Design (UCD). Dalam era digitalisasi yang pesat, teknologi informasi semakin penting dalam dunia bisnis, terutama dalam proses audit internal yang kompleks. Meskipun website audit telah diluncurkan, banyak fitur yang masih belum memenuhi kebutuhan pengguna, sehingga mengurangi efektivitasnya. Untuk mengatasi tantangan tersebut, langkah-langkah sistematis telah diambil. Proses dimulai dengan identifikasi konteks pengguna, di mana tim mengamati perilaku dan interaksi pengguna dengan website. Selanjutnya, analisis kebutuhan pengguna dilakukan untuk memahami apa yang mereka cari dalam alat audit. Setelah itu, solusi yang dirancang secara inovatif dirumuskan, diikuti oleh evaluasi desain yang melibatkan umpan balik langsung dari pengguna. Hasil dari penerapan UCD menunjukkan bahwa desain website kini lebih sesuai dengan kebutuhan pengguna, yang meningkatkan efektivitas dan efisiensi dalam proses audit. Pengujian fungsionalitas juga menunjukkan peningkatan signifikan, dengan fitur-fitur baru yang lebih intuitif dan mudah digunakan. Dengan demikian, PT XYZ berhasil menciptakan pengalaman pengguna yang lebih baik, meningkatkan kepuasan dan produktivitas tim audit secara keseluruhan.

Abstract

In this research, we introduce the combination of two Blockchain methods. Ripple Protocol Consensus Algorithm (RPCA) and Practical Byzantine Fault Tolerance (PBFT) are applied to cryptospatial coordinates to support cultural heritage tourism. The PBFT process is still used until the preparation process to ensure a maximum error of 33%, and every node would add a new chain in all nodes, so PBFT has a slower processing speed than other methods. This research cuts the PBFT process. After the preparation process in PBFT, the data was entered into the RPCA node and was calculated using an equation to minimize errors with a maximum limit of 20%. After this process, the was were sent to the commit process to store the data in all connected nodes in the Blockchain network; we call this combination of two methods R-PBFT. Combining the two methods can enhance data processing security and speed because it still uses the PBFT work combined with the speed of RPCA. Furthermore, this method uses a fault tolerance value from the RPCA of 20% to enhance data processing security and speed.

Abstract

Digital transformation drives the adoption of e-procurement systems as a strategic instrument for enhancing efficiency, transparency, and corporate governance. However, the realization of these benefits is critically dependent on the technical performance and reliability of the system in use. This study aims to conduct a quantitative evaluation of the performance and reliability of the e-procurement website belonging to PT XYZ, a private company in Surabaya, utilizing the international software quality standard framework ISO/IEC 25010. The primary contribution of this study lies in the methodological synthesis that maps empirical performance metrics generated via load testing with Apache JMeter onto the characteristics of Performance Efficiency and Reliability. The testing was conducted on two critical transactional scenarios, namely new user registration and login, with varying virtual user loads (10, 50, and 100 users). The metrics analyzed included response time, throughput, and error rate. The test results indicated that the system exhibited excellent time-behaviour in the login scenario, with an average response time of 562 ms under a 100-user load, which falls within the "excellent" category according to industry benchmarks. The most significant finding was the consistent 0% error rate across all scenarios, affirming a perfect level of availability and fault tolerance. Consequently, it is concluded that the PT XYZ e-procurement website meets the essential software quality criteria to support critical B2B business processes, and the methodology employed can serve as a robust evaluation model for similar corporate systems.

Abstract

In this research discusses the implementation of GIS to solve the problems that often occur in Islamic Boarding Schools, especially Islamic Boarding Schools of Amanatul Ummah Surabaya. The problem faces at Amanatul Ummah is still using the manual system in determining rooms for new students, so many rooms in this Islamic boarding school an overcapacity. The alternative solution to this problem is to develop a system that could be mapping and know the capacity of each room along with the number of room occupants so that to reduce excess capacity. This application can help determine and show the capacity of each room because the safety and comfort of student in Islamic Boarding School could be influenced by health and social factor. Other than that a vision of the Amanatul Ummah especially superior, whole, and glorious of a human being can be achieved

Abstract

Traffic accidents are caused by several factors, especially due to driver fatigue. To minimize accidents caused by human negligence, developing a prototype microsleep detection system to trigger an alarm is necessary. This research uses Histogram Oriented Gradient and Support Vector Machine methods to detect objects. The programming language used is Python, using the dataset from the Idlib face landmark as a marker in the face point area, which will then be calculated based on the eye aspect ratio. This system is implemented using video input captured using a webcam in real-time. The output of this system uses a buzzer to alert the driver. In this study, the test results were obtained well, carried out with 2 test scenarios with a distance of 40cm - 100cm and testing light levels of 33 lux to 226 lux. From these results, the accuracy results were obtained at 88% each.
