Abstract

About 10% of collisions resulting in death is due to frontal collision. Head-on Collision Avoidance System (HCAS) is a device that can prevent a frontal collision by means of braking or evasive. Two ultrasonic sensors are used to monitor the vehicles in front and to the right. Two distances are observed by sensors, then become input for decision making system based on fuzzy logic. This decision-making system output is the vehicle forward, stop, or evasive movement. Simulation result using a remote control car proves that the decision making system designed with fuzzy logic can work with a success rate of over 90%.

Abstract

Standard headlights will shine with a fixed intensity even though the environmental light changes. High-intensity lights sometimes make other drivers glare and potentially cause accidents. Adaptive Light Control (ALC) is a car headlights control system that can automatically adjust the intensity of the lamp according to the intensity of the light environment. In this research, we developed ALC which was able to regulate the intensity of the lamp according to the intensity of the environmental light including the light of the car in front. Light settings are performed using a fuzzy control system by utilising environmental light intensity and the distance of the car to the object as input. The developed ALC system was tested on remote control cars equipped with sensors and microcontrollers. The intensity of headlight begins to fade on the distance of the car to the object of 92 cm for objects in front of, 108 cm for objects on the left, and 22 cm for objects on the right.

Abstract

Industri budidaya ikan di Indonesia berjumlah 583 perusahaan dengan 50,6% berfokus pada ikan air tawar. Banyaknya penggunaan tenaga manusia membuat budidaya kurang efektif. Pengendalian ketinggian dan aliran air dalam kolam ikan sangat penting untuk memastikan lingkungan yang sehat dan optimal bagi pertumbuhan ikan. Sistem kendali terdistribusi diterapkan untuk meningkatkan efisiensi terutama ketika menghadapi jumlah kolam yang banyak dan jarak yang jauh. Sistem ini menggunakan HMI sebagai perangkat lunak utama pengontrolan, dan metode logika fuzzy untuk mengatur aliran dan ketinggian air. Dalam proyek ini, terdapat dua LCU, yaitu: LCU 1 mengendalikan ketinggian air menggunakan metode PID, dan LCU 2 mengendalikan aliran air menggunakan metode PID, keduanya diatur oleh master control. Hasil pengujian menunjukkan LCU 1 dengan overshoot 0%, rise time 14,65 detik, settling time 14,67 detik, dan error steady state 0. Sementara LCU 2 menghasilkan overshoot 0%, rise time 138 detik, settling time 141 detik, dan error steady state 0. Respon dari LCU 1 digunakan sebagai respon utama, diproses oleh MCU dan ditampilkan pada HMI.

Abstract

Konverter DC-DC umumnya dikategorikan ke dalam dua kategori, yaitu: isolated dan non-isolated. Topologi konverter non-isolated tidak memiliki isolasi galvanik antara masukan dan keluaran, variasi pada masukan secara langsung mempengaruhi keluaran konverter. Jumlah komponen pada rangkaian non-isolated adalah kurang secara jumlah jika dibandingkan dengan konverter isolated. Namun, permasalahan yang muncul dan perlu ditangain adalah rasio duty cycle, penguatan tegangan yang buruk, dan sirkuit tambahan untuk operasi yang optimal. Pada penelitian ini dibahas secara singkat mengenai model switching dari two state buck boost converter dibandingkan dengan manual buck-boost converter berdasarkan metode eksperimen yang dilakukan untuk melihat tegangan masukan dan keluaran apakah terjadi perubahan kenaikan atau penurunan tegangan DC. Pada penelitian ini, rangkaian konverter tipe buck dapat menurunkan tegangan dari 4-12V ke 3,2-3,5V dan tipe boost dapat menaikkan tegangan dari 2-12V ke 2V-16,5V. Berdasarkan hasil pengujian, rangkaian osilator mampu membangkitkan modulasi lebar pulsa dan mengatur duty cycle dari 79% hingga 94% karena keterbatasan penggunaan komponen dan terjadi drop tegangan pada rangkaian buck-boost dengan beban rheostat 330Ohm/2,5A. Rangkaian konverter two state buck-boost dapat bekerja sesuai dengan fungsinya dengan pengaturan parameter duty cycle dan juga manual buck-boost bekerja sesuai prinsip kerjanya untuk pebandingan penurunan dan kenaikan tegangan berdasarkan frekuensi yang berbeda. Pengembangan selanjutnya adalah variasi beban dan fungsi buck-boost yang berbeda, seperti tegangan keluaran konstan terhadap perubahan masukan dan juga duty cycle dengan range yang lebih besar.

Abstract

The rising number of dementia patients worldwide is a significant concern. Dementia, marked by deteriorating memory, language, problem-solving abilities, and other cognitive skills, affects millions globally. According to the World Health Organization (WHO), over 55 million people currently live with dementia. Dementia's impact on patients, their families, and healthcare systems is substantial. Patients often need continuous supervision and care, posing challenges for caregivers. Wandering is a frequent issue among dementia patients, leading to safety risks and a high chance of getting lost. Innovative technological solutions, such as portable monitoring devices, are crucial in tackling these issues. A smart bracelet with Global Positioning System (GPS) can be vital for ensuring dementia patients' safety. These devices provide real-time location tracking, giving caregivers and family members peace of mind by enabling them to quickly locate patients who wander off. This makes the bracelet highly effective for monitoring dementia patients' locations, as it will send notifications to a messenger application on a smartphone with a link to the patient's location if they move beyond a 20-meter radius from home. The bracelet uses GPS for distance and location tracking. The patient's location is pinpointed by the intersection of latitude and longitude coordinates. The device has a minimal margin of error, with a latitude error of 0.003% and a longitude error of 0.008%.

Abstract

This research focuses on describing and discovering a model for developing the Islamic boarding school curriculum at the junior high school level in integrated Islamic schools, where the presence of Islamic boarding schools is an integral part of the education model. Initially, as a full-day school, the concept of boarding school or Islamic boarding school emerged. In facing the expansion and development of Islamic schools, developing a curriculum model based on current products and the education market is essential. Education actors must be wise in preparing curriculum composition or structure that can adapt to recent developments. Actors in Islamic religious education and science will contribute maximally to determining curriculum content so that the Islamic Boarding School curriculum becomes at the forefront. This research aims to explore the integrated Islamic school model starting from the philosophical roots of the curriculum. By taking the example of the Ibnu Salam Nurul Fikri Boarding School in Serang, Banten, as a pioneer of integrated Islamic school-based Islamic boarding schools, it was found that the curriculum structure always refers to the national curriculum. Educational institutions' religious and scientific camps have become an unavoidable dualistic reality. This research seeks to develop the Islamic Boarding School curriculum structure at integrated Islamic schools at the junior high school level. The field study results show that the Islamic boarding school continues to prioritize science (dikes) as its curriculum philosophy, intending to produce quality graduates for state universities. This research uses qualitative methods with literature study and interviews as procedures, creating descriptive data from participants in written and oral form.

Abstract

The idealism of the nation and state is often reduced by political behavior that does not reflect maturity and statesmanship. Both by politicians and officials as well as by the community and the people. This can be seen in people's lives when approaching general elections that consider there is no problem with the practice of Money Politics. This study aims to determine the concept of constitutional political education from an Islamic perspective, its implementation in Formal, Informal and Non-formal Education that applies the Tadabbur Methodology and Thematic Interpretation of Constitutional Political Education from an Islamic Perspective. The results of the research that the author finds are the concept of political education, constitutional education in an Islamic perspective associated with Bloom's theory, that education can be felt and produced cognitively, affectively and psychomotorly. If political education can be realized in this picture, the success of political education can affect the world of education, both formal, informal and non-formal. In conclusion, the idealism of nation and state is often threatened by political behavior that does not reflect maturity and statesmanship, both on the part of politicians and officials as well as the community and the people.

Abstract

Surah Al-Fâtihah, as the greatest surah in the Qur'an, can be obtained, evaluated and tested for the truth of its knowledge through five levels of understanding (Fiqh), namely: Fiqh al-Lughah (Language and the Nature of Knowledge), Fiqh al-Munâsabah (Correlation and Building Structure of Knowledge), Fiqh al-Hidâyah (Instructions and Methods for Obtaining and Testing the Truth of Knowledge), Fiqh al-Idârah (how to Manage the Benefits, Solutions and Neutrality of Knowledge), and Fiqh al-Hadârah (ways of Knowledge solve the problem). The tadabbur analysis of Surah Al-Fâtihah was carried out using an integration approach of three perspectives, namely: First, the perspective of the Philosophy of Science, Second, the perspective of Bloom's Taxonomy regarding the Dimensions of Knowledge, and Third, the perspective of the Tadabbur Methodology. Through a combination of the three perspectives, it can be formulated that Surah Al-Fâtihah is a surah which means Opener, has a philosophy of meaning of victory (Al-Fath) based on openness; both thoughts, heart (beliefs and emotions), and attitudes (behavior and morals). In the context of Constitutional Politics, this Surah inspires constitutionalism as the spirit needed in the formation of a Constitution. Up to the level of the Living Constitution which contributed to the civilization of all humans in the world. This research aims to determine the concept of implementing the Quranic tadabur Surah Al-Fatihah in constitutional politics
