Abstract

English, being an international language, plays a significant part in daily life worldwide. Many nations utilize English as their primary language of communication. The lack of a novel approach to English learning—such as the use of contemporary technology—means that kindergarteners at Al-Barkah Kindergarten only learn the language through books. In light of these issues, Al-Barkah Kindergarten developed an Android-based application to teach English via the drill and practice method, hence creating a variance in teaching methods. Because this method applies a learning system in the form of visual, audio, and animation that can attract students' interest in learning language, the application design results show that the learning method is effective and that a solution, especially for Al-Barkah Kindergarten students, can easily understand the learning material.

Abstract

Smartphone technology, especially Android smartphones, has advanced quickly in terms of their function as smart and communication devices. Their capacity to function as remote control tools, enabling users to view and manage electronic gadgets via an Internet connection, is one notable advancement. Through the use of the Internet connection as a bridge between devices, smartphone-based remote control indirectly makes it easier to monitor and manage electrical gadgets. Uncontrolled electricity use and instances of high power consumption that occur when people forget to turn off equipment provide a challenge. The author suggests using the prototyping method, in which a prototype is created at the beginning stage for later development, to overcome this problem. Through

Abstract

The North Sumatra Basin is one of the major sedimentary basins in Indonesia with significant hydrocarbon potential. However, exploration in this region faces challenges due to overpressure, which can increase operational risks such as blowouts. This study aims to analyze pore pressure and overpressure formation mechanisms in Well Al using the Eaton method and a crossplot approach between sonic and density data. The analysis results indicate that the top overpressure is identified at a depth of 8,500 ft in the Keutapang Formation and continues into the Baong, Bampo, and Parapat Formations. Wireline log evaluation indicates anomalies in the sonic, neutron, and density logs, which are consistent with disequilibrium compaction patterns. The Dutta crossplot results also confirm the dominance of smectite minerals without transformation into illite, reinforcing that the primary overpressure mechanism is loading due to disequilibrium compaction. Accurate pore pressure modeling is necessary to improve drilling safety and efficiency in this area.

Abstract

Errors in estimating pore pressure can cause blowouts during the drilling process, especially in overpressured zones. This study focuses on pore pressure estimation in the North East Java Basin using the approach, which is validated with field data. The well log data analyzed include resistivity, density, sonic velocity, and porosity, which are used to detect the presence of overpressure zones and identify reservoir potential. The results show that the overpressure zone begins at a depth of 4600 feet and lasts up to 9000 feet. The interval between 4800 to 7300 feet is identified as a potential reservoir, while seal rocks are found at 4000–4600 feet. The cross plot between sonic and density parameters shows the dominance of smectite minerals, indicating that perfect compaction has not occurred due to trapped fluids. This finding strengthens the suspicion that the overpressure formation mechanism is dominated by sediment loading. Precise pore pressure estimation is needed to reduce operational risks and optimize hydrocarbon exploration in this area.
