Abstract

Acute myeloid leukemia (AML) adalah salah satu tipe kanker darah yang mengakibatkan sumsum tulang tidak dapat menghasilkan sel leukosit jenis myeloid yang matang. Pada dasarnya diagnosa penyakit AML menggunakan basis perhitungan jumlah persentase relatif sel leukosit dalam darah. Kesalahan dalam perhitungan jumlah sel dapat berimbas pada kurang tepatnya diagnosa yang dibuat. Dalam pemrosesan citra apusan darah secara digital, salah satu hal yang masih menjadi kendala adalah sel darah yang saling bersinggungan dan bahkan tumpang tindih. Penelitian ini mengusulkan perpaduan algoritma active contour without edge (ACWE) yang dikombinasikan dengan watershed distance transform (WDT) untuk dapat mengatasi permasalahan objek sel darah yang tumpang tindih. ACWE digunakan untuk melakukan segmentasi objek sel darah berbasis perhitungan inside energy dan outside energy sementara WDT diimplementasikan sebagai algoritma pemisah objek dengan memanfaatkan memanfaatkan transformasi jarak dari setiap piksel ke nilai piksel non-zero terdekat. Hasil penelitian menunjukkan dari total 876 objek sel leukosit, terdapat 734 objek yang dapat disegmentasi dengan baik dan sisanya sebanyak 142 objek masih belum dapat diseparasi dengan tepat. Nilai ini menunjukkan bahwa perpaduan algoritma ACWE dan WDT dapat memisahkan 83,789% objek sel leukosit dari citra AML M1, M2 dan M3.

Abstract

Many educational institutions worldwide now use blockchain to verify electronic document, often relying on Ethereum 1.0, which uses proof of work (PoW) or proof of authority (PoA). However, Ethereum 2.0, launched in 2022 by Ethereum Foundation operates on proof of stake (PoS). This study provides comparative analysis of PoS and PoA consensus in Ethereum environment specifically focusing on performance and scalability in the context of academic transcript databases. To demonstrate this, a student academic reputation information system was developed using two different blockchain technologies: Ethereum 1.0 with PoA and Ethereum 2.0 with PoS. This setup was used to obtain comparative analysis data for the two blockchain systems by measuring the throughput and latency. We observed how these platforms responded to an increasing number and frequency of transactions with Hyperledger Caliper. Results indicates that in performance testing, both consensus mechanisms exhibited. Scalability tests revealed that both consensus mechanisms experienced increased latency with higher loads. However, PoA system was superior in average throughput and latency than PoS system except in high transaction of data addition. The experiment result show that PoA system better than PoS system in context of academic transcript databases, making it more suitable to be implemented on that context.

Abstract

Islamic boarding schools (pesantren) are Islamic educational institutions in Indonesia that must adapt to technological developments. Developing a digital-based management information system is one of the solutions to support effective data management and administrative processes. However, data collection at Al-Muayyad Windan Islamic Boarding School is still carried out conventionally, which often causes inefficiency in managing student information. Therefore, this research aims to develop a student management information system using an agile software development methodology, namely the Scrum model, which allows iterative development and continuous feedback. The implementation of Scrum was successfully carried out through stages including Product Backlog, Sprint Planning, Sprint Backlog, Sprint, Sprint Review, and Retrospective. The resulting system has passed feasibility testing and usability evaluation. The SUS test involving 10 respondents produced an average usability score of 73, categorized as Acceptable on the Acceptability Range, Grade C on the Grade Scale, and Good on the Adjective Rating. These results indicate that the developed system is functionally feasible, user-friendly, and capable of supporting digital transformation in Islamic boarding school management.
