The purpose of this study is to predict the total end breakage per machine in 40 hrs of cotton yarn in a rotor spinning machine based on yarn count (yarn count), rotor speed (rotor speed), opening roller speed (opening roller speed) and residual trash content in draw frame sliver. . This study uses an artificial neural network (ANN) method in predicting a desired output. Furthermore, the artificial neural network is modeled with several model variations. From several modeling and testing carried out, starting from varying the number of nodes, the amount of alpha, the number of hidden layers, the number of iterations, it can be obtained that the results of using an artificial neural network with 1 hidden layer, 3 nodes, alpha of 0.3 with 50,000 iterations have more optimal results compared to the others because the resulting output is close to the target with an R-squared value of 0.984968. This shows that there is a large or close correlation between the actual variables and the variables in the artificial neural network. The novelty of this study is the use of ANN for the first time in predicting the total end breakage per machine in 40 hrs of cotton yarn in a rotor spinning machine. This method can facilitate top management and especially the Quality Control section in making decisions to set the parameters of the rotor machine in order to minimize the occurrence of yarn end breakage per machine in 40 hrs.

Earthquakes often cause casualties and damage to buildings, hence the importance of calculating the planned load in the design of the structure. Linear analysis is commonly used, but is considered less accurate for understanding the behavior of structures in response to large earthquakes. Therefore, non-linear analyses such as the pushover method, which apply a gradual lateral force to a building until it reaches a specific collapse pattern to understand the structural response to a large earthquake, are needed. The purpose of this study is to determine the maximum earthquake force that can be accepted by the BRI Sisingamangaraja building in Medan, resulting in the capacity and performance limits of the building. This pushover analysis uses the Sap 2000 program, from the results of the analysis it is known that the greater the force given, the greater the displacement that occurs in the building. The BRI KC Sisingamangaraja Medan building can receive a maximum earthquake force of 7,149,921 kN and based on ATC-40 the building's performance limit is in the category of Immediate occupancy (IO) level, which means that the building can be used immediately or used after an earthquake.

Dalam era digital yang semakin maju, keamanan pesan rahasia menjadi salah satu fokus utama dalam bidang keamanan informasi. Salah satu teknik yang sering digunakan untuk melindungi pesan adalah enkripsi Vigenère. Namun, kelemahan utama dalam teknik ini terletak pada distribusi kunci enkripsi yang berbentuk string biasa, sehingga rawan terhadap ancaman keamanan. Untuk mengatasi permasalahan ini, penelitian ini mengusulkan modifikasi pada enkripsi Vigenère dengan menggabungkan steganografi dan pendekatan dua kunci, yaitu kunci string biasa dan kunci berbasis waktu penyisipan. Tujuan dari penelitian ini adalah untuk meningkatkan keamanan distribusi kunci serta kompleksitas sistem enkripsi guna meminimalisir risiko pembobolan. Metode yang digunakan dalam penelitian ini adalah penggabungan On-time Pad (OTP) dan Message Digest 5 (MD5) untuk memperkuat distribusi kunci. Pendekatan ini juga memanfaatkan steganografi untuk menyembunyikan pesan secara lebih aman.Hasil penelitian menunjukkan bahwa metode yang diusulkan berhasil meningkatkan keamanan dan kompleksitas sistem enkripsi. Distribusi kunci menjadi lebih sulit dipecahkan karena adanya kombinasi dua kunci yang dinamis, meskipun tantangan dalam pengelolaan kunci yang rumit masih perlu diselesaikan. Penelitian ini diharapkan dapat memberikan kontribusi signifikan dalam pengembangan teknik enkripsi dan steganografi yang lebih aman di masa mendatang

The mangrove ecosystem plays a vital role in maintaining coastal environmental balance. However, mangrove degradation continues to increase due to a lack of public awareness and education about its benefits and conservation methods. This study aims to develop a mobile-based educational application focused on introducing mangroves, highlighting their benefits, and demonstrating conservation techniques. The Waterfall method was applied in its development, consisting of the stages of requirements analysis, design, implementation, testing, and maintenance. This method was chosen for its structured and systematic approach, allowing for a well-planned application development that meets user needs. Testing results indicate that this application provides educational information interactively and is easily accessible to a broad audience, especially students and coastal communities. This application is expected to raise public awareness of the importance of mangrove conservation and serve as an effective solution in disseminating information about the mangrove ecosystem

Background: Chronic kidney disease is a condition in which the body is unable to maintain balance in metabolism, fluids, and electrolytes due to irreparable damage to kidney function. One of the problems that can occur in hemodialysis patients is thirst. Therefore, it is important to treat thirst. Gargling with peppermint water is one way to quench thirst and overcome it.Objective: The purpose of this study was to find out whether gargling with peppermint water is effective in reducing thirst in kidney failure patients undergoing hemodialysis at Harapan dan Doa Hospital Bengkulu.Method: This study used quasi-experimental methods. The population in this study is 65 patients suffering from chronic kidney failure and undergoing hemodialysis at Harapan dan Doa Hospital in Bengkulu City. The total sample of this study amounted to 36 people who followed the treatment in Harapan dan Doa Hospital Bengkulu, which were divided into two groups, namely the intervention group of 18 people and the control group of 18 people. A purposive sampling technique was used in this study. In addition, visual analog scale instruments for assessing thirst were used as questionnaires to assess thirst.Result: The study showed that there was a difference in average thirst sensation between the intervention groups and the control group. For the Mann-Whitney statistical test for thirst, the p-value was 0.026 (p-value ≤ α 0.05). This suggested that gargling with peppermint water affected thirst in hemodialysis patients.Conclusion: Hence peppermint water gargle therapy may be recommended as a non-drug treatment to control taste thirst in renal failure patients undergoing hemodialysis.

In the context of the rapid growth of Islamic banking in Indonesia, it is essential to understand how the values of Pancasila can be integrated into financial practices to enhance public trust and support sustainable development. The aim of this research is to explore and analyze the challenges and opportunities in harmonizing Pancasila values with Islamic principles within the Indonesian banking system. The research employs a qualitative approach using in-depth interviews and document analysis to gain comprehensive insights from various stakeholders in the banking sector. The results indicate that there are common values between Pancasila and Islamic principles; however, challenges include differing interpretations and uneven understanding among industry players. This research recommends the development of policies that support the synergy between these two values, as well as training for stakeholders to improve understanding and harmonious implementation in banking practices.
