This study aims to analyze and compare the optimization of paddy fields under swamp and non-swamp conditions, as well as to determine effective irrigation de…
This study aims to test the performance of an automatic rack-type dryer with electric heaters in the drying process of sardine crackers (sardinella sp.). This study was conducted using a descriptive method with varying drying temperatures of 50°C, 55°C, and 60°C and fan speeds of 1000 rpm, 1200 rpm, and 1400 rpm with three repetitions. Observed parameters included drying rate, material weigh…
The modification of an Internet of Things (IoT)-based smart greenhouse and the analysis of solar panel energy efficiency involve a comparative calculation of conventional electrical energy and the electrical energy generated by solar panels used to power the smart greenhouse system. This study aims to compare the electrical energy generated and consumed by solar panels with that of conventional…
This study implements and compares the performance of the IndoBERT deep learning model in analyzing the sentiment of Gojek application reviews using 3-class and 5-class schemes. Data was extracted via web scraping, yielding 66,709 raw reviews, which were then preprocessed and balanced into 23,115 (3-class) and 32,899 (5-class) datasets. Training was executed with an 80:10:10 ratio across six sc…
Two-phase flow is a flow involving two different fluids flowing simultaneously in a channel. The characteristics of two-phase flow are more complex than single-phase flow because they are influenced by phase interaction, phase distribution, superficial velocity, and friction occurring during the flow process. These interactions cause pressure distribution changes along the pipe and require furt…
The distribution of Direct Cash Assistance from Village Funds (BLT-DD) in Lubuk Seberuk Village is still carried out manually, which poses a risk of inaccuracies in determining eligible beneficiaries. Therefore, the village government requires a system that can support the selection process objectively based on predetermined criteria. This study aims to implement the K-Means and Simple Multi-At…
Nutrient concentration stability is an important factor in hydroponic cultivation because it affects nutrient absorption and plant growth. Manual nutrient management often leads to inconsistencies in nutrient concentration due to delays in monitoring and measurement errors. This study aimed to design and evaluate the performance of an Internet of Things (IoT)-based automatic Total Dissolved Sol…
The waste transportation system in Baturaja Barat and Lubuk Batang Districts, Ogan Komering Ulu Regency South Sumatra Province, is still inefficient. This is indicated by non-optimal routes, limited fleet availability, and a mismatch between vehicle capacity and waste volume. Under existing conditions, 45 temporary disposal sites (TPS) are served by two vehicles operating two trips per day; how…
The racutan harvesting method and manual sorting of coffee cherries often result in low quality and inefficiency in terms of time and labor. This occurs because unripe cherries are mixed with ripe ones, thereby reducing export quality, while manual color-based sorting is highly subjective. This study aims to design and evaluate the performance of an automated coffee cherries ripeness sorting ma…
Riverside residential areas in Ilir Timur II District, Palembang City, are characterized by high population density and face challenges related to household solid waste generation, limited waste management infrastructure, and low community participation. This study analyzes the spatial distribution of household solid waste generation and evaluates waste management performance using Geographic I…
The rapid growth of social media has enabled the misuse of comment sections as a medium for promoting online gambling. The high volume of comments makes manual moderation ineffective, thus requiring an automated classification system. This study aims to develop a classification system for online gambling comments using the IndoBERT model and to evaluate its performance based on accuracy, precis…
Dissimilar metal welding between carbon steel and stainless steel is widely used in industrial applications due to its ability to combine good mechanical properties with excellent corrosion resistance. This study aims to investigate the effect of welding current variation on the mechanical properties and microstructure of dissimilar welded joints between ASTM A36 steel and AISI 304 stainless st…
DANA has become one of the most popular e-wallet applications in Indonesia. This development has elicited various reactions and responses from users in the form of reviews. These reviews can provide important insights for improving the quality of the application's services. This study aims to conduct sentiment analysis on user reviews by utilizing Long Short-Term Memory (LSTM) as the model arch…
Phishing is a form of cyberattack that exploits fraudulent websites to obtain users’ sensitive information. This study aims to compare the performance of the XGBoost machine learning algorithm and CNN 1D deep learning in detecting phishing URLs using tabular URL data. XGBoost was chosen because it is effective in handling tabular data and capable of modeling nonlinear relationships among feat…
Dissimilar welding between carbon steel and stainless steel is widely used in industry because it combines the advantageous properties of both materials. However, differences in the physical and metallurgical characteristics of the two metals can affect the quality of the welded joint. This study aims to analyze the effect of V, X, and K groove variations on the mechanical properties of dissimi…
The application of the strip mine method at PT Dizamatra Powerindo altered the topography into a massive basin that functions as a catchment area, causing rainwater to flow directly and accumulate in the mine opening area. The DP pit 3 area is currently a void (mine lake) filled with water and mud, which is planned to be re-mined. The research method uses a quantitative approach through direct …
Alzheimer’s disease is a progressive neurodegenerative disorder that is the leading cause of dementia. The use of Magnetic Resonance Imaging (MRI) in ResNet18-based classification can be hindered by the presence of noise, particularly Rician noise, which obscures important structural details and reduces model performance. This study employs the Nonlinear Activation Free Network (NAFNet) to im…
