API abuse on lightweight edge gateways has intensified as microservice-based services expose many REST endpoints to heterogeneous clients. Conventional per-identity rate limiting, such as static token buckets, is frequently bypassed through distributed bots and identity rotation, while legitimate burst traffic may be rejected and degrade user experience. This study proposes Adaptive Rate Limiting with Verifiable Delay Functions (ARL-VDF), which couples a lightweight risk score with selective VDF challenges to impose a tunable sequential-computation cost on suspicious clients without forcing aggressive dropping for low-risk users. The gateway continuously derives a per-identity risk score from short-window request rate, error tendency, and identity freshness, then maps the score to a target delay bounded by  and . Evaluation uses a 600-second discrete-event simulation on a mixed workload consisting of normal clients, legitimate bursts, and distributed attackers. Compared with a static token bucket baseline, ARL-VDF maintains full success for legitimate traffic, reduces attacker throughput that passes the gateway, and keeps verification overhead within a fixed budget on the edge device. The results indicate that combining adaptive control with verifiable sequential cost can improve availability and fairness on resource-constrained edge gateways without resorting to aggressive dropping.

Data security is a critical aspect in the digital era due to the increasing exchange of sensitive information through electronic media. One widely used approach to protect data confidentiality is cryptography, particularly asymmetric encryption algorithms. This study aims to analyze the implementation of the Rivest–Shamir–Adleman (RSA) algorithm as a data security mechanism through an encryption and decryption process. The research method used is an experimental approach by implementing the RSA algorithm in a text-based data security simulation. The stages include key generation, encryption, and decryption processes, followed by analysis of the correctness and effectiveness of the algorithm in maintaining data confidentiality. The results show that the RSA algorithm is capable of converting plaintext into unreadable ciphertext and successfully restoring it to its original form through the decryption process using the correct private key. This confirms that RSA provides a high level of security based on the difficulty of factoring large prime numbers. The implication of this study is that the RSA algorithm can be effectively applied to secure sensitive data transmission in information systems, especially in environments requiring strong authentication and confidentiality.

The quality of assessment instruments plays an important role in determining the accuracy of measuring student learning outcomes in science learning in elementary schools. A good test instrument must meet certain criteria, such as validity, reliability, difficulty level, and discrimination power. This study aims to analyze the quality of daily science test items in grade VIc elementary schools based on these four criteria. The study used a quantitative. The subjects were 19 sixth-grade students, while the instrument analyzed consisted of 25 multiple-choice questions. Data processing and analysis were carried out using Microsoft Excel to calculate item validity through item correlation with total score, test reliability using internal consistency, difficulty level index, and discrimination index. The analysis results showed that 17 questions (68%) were declared valid, while 8 questions (32%) were invalid and needed to be improved. The results of the reliability test indicated that the test instrument had good reliability and was suitable for use as a measuring tool for student learning outcomes. Judging from the level of difficulty, 20 questions (80%) were moderate and 5 questions (20%) were easy, indicating a relatively balanced level of difficulty. Based on the discrimination power, 16 questions (66%) had very good discrimination power, 4 questions (16%) were good, 4 questions (16%) were sufficient, and 1 question (4%) was poor. Based on these findings, it can be concluded that the quality of the sixth grade science daily test questions is classified as good and the test instrument is suitable for use, but improvements are still needed on invalid questions and those with low discrimination power so that the quality of the assessment is more optimal. This study emphasizes the importance of teachers' abilities in compiling and analyzing test items to ensure that the assessment of science learning is objective, valid, and reliable.

Password security is a critical component in protecting information systems, as passwords are often the primary target of various attacks, particularly brute force attacks. A brute force attack works by systematically attempting all possible character combinations until the correct password corresponding to a stored hash value is found. Therefore, the choice of an appropriate hash algorithm plays a significant role in determining a system’s resistance to such attacks. This study aims to analyze and compare the password cracking time of MD5, SHA-256, and SHA-512 hash algorithms under brute force attack scenarios. The research methodology involves generating hash values from a set of test passwords using each hash algorithm, followed by conducting brute force attacks to recover the original passwords based on the generated hash values. The collected data are analyzed by measuring the time required to crack passwords for each algorithm. The results indicate that MD5 has the fastest cracking time compared to SHA-256 and SHA-512, indicating a lower level of resistance to brute force attacks. SHA-256 demonstrates better security than MD5 but remains less resistant when compared to SHA-512. The SHA-512 algorithm requires the longest cracking time, reflecting the highest level of resistance to brute force attacks among the tested algorithms. In conclusion, hash algorithms with larger bit lengths provide stronger protection against brute force attacks and are more suitable for secure password storage in information systems.

The study provides empirical evidence that can support managerial decision-making in developing effective pricing strategies within the agribusiness sector.

One of the most common occupational health risk factors found in industrial areas is noise, and long-term exposure ≥85 dB(A) for more than 8 hours has the potential to cause progressive and permanent Noise-Induced Hearing Loss (NIHL). The risk of NIHL increases if workers do not use Ear Protection Equipment (APT) optimally and have certain individual factors such as age, working period, and length of exposure. This study aims to determine the relationship between the use of APT and worker factors with hearing loss due to noise in PT HMK II Palembang City in 2025. This study uses an analytical quantitative design with a cross sectional approach. A sample of 55 respondents was selected through purposive sampling technique. Data was collected using a questionnaire and analyzed by chi-square test. The results showed that there was a significant relationship between the use of APT (p=0.000) and there was no significant relationship between, the age of workers (p=0.838), working time (p=0.290), and length of work (p=0.172) and noise-induced hearing loss. The use of APT has been shown to be associated with a reduced risk of noise-induced hearing loss, although age, length of employment, and length of work did not show a significant relationship.

Postoperative pain is a common clinical condition experienced by patients after surgical procedures and may hinder the recovery process if not properly managed. In addition to pharmacological therapy, safe and effective non-pharmacological interventions are needed, one of which is early mobilization. This study aimed to analyze the effect of early mobilization on pain reduction in postoperative surgical patients. A scoping review method was conducted based on the Arksey and O’Malley framework. Literature searches were performed using ScienceDirect, PubMed, and Google Scholar databases with a PICO strategy, including articles published within the last five years. From a total of 167,948 identified articles, 10 studies met the inclusion criteria and were included in the analysis. The results showed that early mobilization performed gradually and according to patients’ clinical conditions had a significant effect on reducing postoperative pain intensity. In addition, early mobilization was associated with improved comfort, enhanced functional recovery, and faster postoperative rehabilitation without increasing the risk of complications. Although variations were found in the timing and type of mobilization across studies, overall evidence supports that early mobilization is safe and effective. In conclusion, early mobilization can be recommended as an evidence-based nursing intervention for postoperative pain management.
