Abstract

The problem of unbalanced data is important in the field of Data Mining. Dataset with unbalanced classes is a dataset whose frequency of occurrence of certain classes is very much different from other classes. This imbalance problem will bias the classifier's performance. Many researchers have examined both the development of algorithms and modifications to the preprocessing stage to overcome this problem. This study discusses the comparison of One Class Classification algorithms, namely Elliptic Envelope and Isolation Forest on unbalanced data. From this study, the Elliptic Envelope Method showed better results compared to the Isolation Forest method with 80.28% recall testing and 80.28% precision while Isolation Forest showed 46.95% recall results and 46.95% precision.

Abstract

In the world of Education today, some problems often occur in high schools, namely academic procrastination, which is still carried out by students. Academic procrastination is the tendency of individuals to deliberately delay the start or completion of important and timely tasks on academic tasks. To reduce this impact, it is necessary to have self-control in learning that can support the achievement of learning goals by regulating and controlling a learning system known as self-regulated learning. This study aims to determine the relationship between self-regulated. I was learning with. Academic procrastination in SMAN 1 Tambun Selatan students. This study uses a correlational method with a quantitative approach. The sample in this study amounted to 110 students from class X and XI SMA Negeri 1 Tambun Selatan taken using a simple random sampling technique. The analysis technique used is the product-moment correlation technique with a significance level of 5%. Based on the analysis results, it is known that the F value is 0.798, and the significance value is 0.000 (P <0.05). The results showed a relationship between self-regulated learning and academic procrastination in students of SMA Negeri 1 Tambun Selatan.

Abstract

Freshwater fish farming must pay attention to the condition of the water content in the pond and the water quality in the pond. Fish will feel comfortable if the efficiency of oxygen levels and pond water content is maintained. Freshwater fish farming needs to optimize crop yields so as not to get losses. The problem that is often encountered is that many fish die in the pond due to lack of water. Irrigation channels leading to fishponds experience blockages. The smoothness of the irrigation channel affects the volume of water in the pond. Blockage of irrigation channels is usually due to garbage trapped in irrigation, causing dirty water to settle and water sequestration to occur in the pond. This tool system aims to improve water quality and increase the efficiency of oxygen levels by using TDS and ultrasonic sensors. The parameter value on the sensor affects the work of the tool actuator. The tool actuator is a water pump that is used as a substitute for irrigation channels and an aerator motor to increase dissolved oxygen in water by moving the propeller on the surface of the pond water. Wireless technology is used for data communication. Because the land of freshwater fish farming ponds is a large area and is far from settlements, wireless communication is suitable for enabling easy and fast access to information and services. In this research, the testing methods used are functional testing and system performance testing. Functional testing is used to prove whether the system that has been implemented can meet the requirements of operational functions as planned. System performance testing is intended to monitor several parameters that can show the ability and reliability of the system in carrying out its operational functions. The result of the overall test is the LoRa communication distance that can communicate up to about 1000 meters, proving that LoRa technology has a strong enough ability in terms of range wireless communication. The PLE (Path Loss Exponent) of the LoRa module with 100 meters in LoS (indoor) conditions is 7.77, while in nLoS conditions in obstructed in-building, it is 10.13. The average error of the ultrasonic sensor type JSN SR-04T is 0.16% and has a difference of ± 1 cm. The TDS sensor with dissolved pool water content has an average value of 142.6 ppm with an error value of 1.05%. The PDAM water content has an average value of 112.1 ppm with a sensor value of 1.38%. The water content of the lime and detergent mixture has the highest observed ppm value, which is an average of 737.33 ppm, with a sensor error of 0.14%. The water pump activates when the pool water is low (when the ultrasonic distance reaches 60 cm), and the aerator activates when the water content is contaminated (when the TDS sensor value exceeds 500 ppm).

Abstract

Regional expenditures are part of regional spending, where these expenditures consist of direct expenditures and indirect expenditures. This studyaims to examine the factors that influence regional expenditures. Variables that affect regional spending consist of Regional Original Income, Gross Regional Domestic Product, Human Development Index, and Population. This research method uses panel data regression with the Fixed Effect Model approach throughEviews 10 to analyze panel data from 2015-2020 in 29 districts and six cities in Central Java province. The study results show that Regional Original Income andGross Regional Domestic Product significantly positively affect Regional expenditure. In contrast, the Human Development Index and Total Population have no significant effect on Regional expenditure.

Abstract

Innovations in modern building design encourage the integration of utility systems, such as rainwater drainage, into structural elements to improve space efficiency and aesthetics. This study aims to analyze the effect of embedding PVC (pralon) pipes as internal drainage channels on the strength and efficiency of reinforced concrete columns. A numerical analysis was carried out using the spColumn software on columns with dimensions of 350 × 600 mm, with variations in the number of 4-inch pipes (zero, one, two, and three). The results show that installing one, two, and three pipes gradually reduced the maximum compressive capacity of the column from 4100 kN to 3930 kN, 3790 kN, and 3650 kN, respectively. Despite this reduction, all column configurations were proven to be safe for sustaining the planned ultimate load of 368.72 kN. Interestingly, the structural–material efficiency of the column increased by up to 4.2% in the three-pipe configuration, as the reduction in concrete volume outweighed the decrease in capacity. It is concluded that the integration of PVC drainage pipes into columns offers a structurally safe, functional, and more material-efficient solution. These findings highlight the potential to reduce the need for external drainage channels, thereby improving spatial efficiency and lowering construction costs. Furthermore, integrating the drainage system into columns allows for cleaner, more minimalist façade designs without conventional piping interruptions, ultimately enhancing the aesthetic value and architectural competitiveness of the building.
