Abstract

Menurut Yaga et al. (2018), Blockchain merupakan sebuah ledger atau buku besar digital yang terdistribusi dari transaksi yang telah ditandatangani secara kriptografis dan dikelompokkan ke dalam blok. Setiap blok dihubungkan secara kriptografis dengan hash blok sebelumnya setelah dilakukan validasi dan menjalani keputusan konsensus. Ketika blok baru berhasil dibuat dari proses mining, data yang terdapat pada blok sebelumnya akan sangat susah atau hampir mustahil untuk diubah maupun dimanipulasi. Berkaitan dengan definisi Blockchain yang telah dijelaskan menurut Yaga et al. (2018), bisa ditarik kesimpulan mengenai definisi Blockchain secara umum, bahwa Blockchain merupakan database terdistribusi yang akan mencatat setiap terjadinya pertukaran atau transaksi dalam setiap blok dan dilindungi dengan metode keamanan kriptografi, sehingga aman dan tidak dapat mudah diubah nilainya. Pada saat ini telah terjadi perkembangan teknologi keempat. Inovasi ini Sejalan dengan semangat pemerintah mewujudkan visi ekonomi digital Indonesia 2020 (Kementerian Komunikasi dan Informatika Republik Indonesia, 2017). Banyak kesadaran atau tidak Aspek teknologi Revolusi Industri Keempat ini menandai lahirnya inovasi inovatif di berbagai bidang seperti pemerintahan, transportasi, transaksi, jual beli, komunikasi, dan Banyak lainnya. Meskipun teknologi blockchain telah berkembang sangat pesat dan banyak digunakan dalam kehidupan sehari-hari masyarakat, Indonesia dinilai memiliki dua tantangan besar. Pertama, Indonesia diyakini belum bisa memanfaatkan sepenuhnya potensi teknologi baru tersebut.Kegiatan pelatihan ini diupayakan dapat memaksimalkan sumber daya manusia yang ada di Indoneisa khususnya kota Balikpapan di tingkat SMK agar dapat mengembangkan teknologi blockchain.

Abstract

Rice is a basic human need that needs to be fulfilled continuously, especially in Indonesia. However, rice production decreased by 2.05% in 2023; the decline was influenced by the lack of rice fields and crop failure due to attacks by plant-disturbing organisms such as Blast, Brown Spot, and even Ricefield Rats. Therefore, expert system technology is useful to help create opportunities for progress in the agricultural sector in overcoming the decline in production. This research utilizes the best method between Euclidean Probability, Bayes` Theorem, and a combination of both in diagnosing plant-disturbing organisms in rice plants. The expert system works by analyzing the symptoms and characteristics of the plants using weight values obtained from the Analytical Hierarchy Process, comparing them with a database of known plant-disturbing organisms, and providing accurate diagnoses and management recommendations. The objectives are to determine which method provides the most accurate diagnosis and to explore how these methods can support sustainable agriculture. The combination of Bayes' theorem with Euclidean methods and Bayes' theorem alone achieved an agreement of 8 out of 10 cases with expert diagnoses. In comparison, the Euclidean method alone achieved an agreement of 9 out of 10 cases. The results demonstrate that the Euclidean Probability method offers a more accurate diagnosis, aligning with expert diagnoses in 9 of the 10 case studies, thus supporting its application in sustainable agricultural practices.

Abstract

Data security and authenticity of ownership of private documents such as land certificates and identity cards or KTP are critical aspects of Indonesia's development process. Database system that has been implemented by the government to secure citizen's personal information is still susceptible to 6 major risk factors, namely, data breaches and theft, damaged data due to virus attacks, limited data storage space, data loss due to system damage, data can be accessed without certain access rights, as well as a lack of system certainty when security threats occur. The rampant cases of data counterfeiting and selling of KTP and land certificates have been a problem for the Indonesian government and have claimed lives for a long time. Based on the problem of public service management, this proposal suggests the development of a public service application for KTP and land certificates based on blockchain titled NFT Document Inspector to help mitigate risks contained in the Indonesian government`s database system as well as ensuring the authenticity of KTP and land certificates. The results of this research will provide insights for policy makers, practitioners and researchers regarding the adoption of blockchain mechanisms to secure citizen's private data in order to accelerate the digital transformation of public services for Indonesia to recover faster and rise stronger, which in this case is KTP and land certificate.

Abstract

Sparrows are one of the most costly pests for farmers, as they can reduce rice yields by 50-60%. Traditional control methods, such as the use of scarecrows, windmills, and pesticides, are often ineffective or cause negative impacts on the environment, such as damage to ecosystems and human health. To overcome this problem, YOLOv8-based object detection technology offers a modern solution to automatically detect bird pests with a high level of accuracy. This research aims to implement the YOLOv8 model on power-efficient embedded devices, such as Raspberry Pi 4 and Google Coral USB TPU Accelerator, to support real-time sparrow detection at an affordable cost. The research was conducted through three main stages, namely collecting bird image datasets to support model training, training the YOLOv8n model to produce reliable bird pest detection, and implementing the model on embedded devices with and without TPU accelerators to evaluate detection performance. The evaluation results show that the YOLOv8 model has high performance with precision 0.91, recall 0.86, mAP50 0.92, and mAP50-95 0.59 after being trained for 300 epochs. Implementation on Raspberry Pi 4 without accelerator only resulted in an inference speed of 0.39 Frame Per Second, while with Google Coral USB TPU, the speed increased significantly to 7 Frame Per Second.  This proves that TPU accelerators are highly effective in supporting real-time object detection. This technology is expected to help farmers protect crops efficiently, reduce losses due to pests, support sustainable agricultural productivity, and contribute to the overall improvement of food security.

Abstract

This study aims to enhance security and efficiency in the digital distribution of salary slips within the XYZ Higher Education environment. The proposed method combines hybrid encryption using the Advanced Encryption Standard (AES-128) and Rivest–Shamir–Adleman (RSA) algorithms, as well as integrates Time-Based One-Time Password (TOTP) for two-factor authentication. This approach ensures the confidentiality of sensitive data while minimizing the potential for data leakage or unauthorized access to employee salary information. In its implementation, the system is designed using the Laravel framework and the Scrum software development methodology, enabling an iterative, measurable, and easily adaptable development process. Testing results indicate that the system can distribute salary slips with an average data encryption time of 0.15 milliseconds per slip (using AES-128), and an average AES key decryption time with RSA of 5 milliseconds per operation over 100 test iterations. Furthermore, when two-factor authentication (TOTP) was applied, the rate of unauthorized access attempts dropped to 0% across 50 brute force attack simulation attempts. Thus, the hybrid encryption approach is proven effective in maintaining data integrity, and the integration of TOTP enhances user authentication security. These quantitative findings establish the system as a more measurable reference model for other institutions seeking to manage sensitive data securely, efficiently, and reliably.Penelitian ini bertujuan untuk meningkatkan keamanan dan efisiensi dalam pendistribusian slip gaji secara digital. Metode yang diusulkan yaitu memadukan enkripsi hibrida menggunakan algoritma (Advanced Encryption Standard) AES-128 dan (Rivest–Shamir–Adleman) RSA, serta mengintegrasikan Time-Based One-Time Password (TOTP) sebagai autentikasi dua faktor. Pendekatan ini memastikan kerahasiaan data sensitif, sekaligus meminimalkan potensi kebocoran atau akses tidak sah terhadap informasi gaji karyawan. Dalam implementasinya, sistem dirancang menggunakan kerangka kerja Laravel dan metodologi pengembangan perangkat lunak Scrum, sehingga memungkinkan proses pengembangan yang iteratif, terukur, dan mudah diadaptasi. Hasil pengujian menunjukkan bahwa sistem dapat mendistribusikan slip gaji dengan rata-rata waktu enkripsi data sebesar 0,15 milidetik per slip (menggunakan AES-128) dan waktu dekripsi kunci AES menggunakan RSA rata-rata 5 milidetik per operasi, pada skenario 100 percobaan. Selain itu, saat pengujian autentikasi dua faktor (TOTP) diterapkan, tingkat kegagalan akses tidak sah menurun hingga 0% pada 50 percobaan simulasi serangan bruteforce. Dengan demikian, enkripsi hibrida terbukti efektif dalam menjaga integritas data, dan integrasi TOTP meningkatkan tingkat keamanan autentikasi pengguna. Hasil kuantitatif ini dapat dijadikan sebagai model acuan yang lebih terukur bagi institusi lain yang ingin mengelola data sensitif secara aman, dan andal.
