Perancangan dan Pembuatan Sistem Penyalaan Lampu Otomatis Dalam Ruangan Berbasis Arduino Menggunakan Sensor Gerak dan Sensor Cahaya

The manual use of household lights poses a problem in the efficiency of electricity use. Humans with various activities often do not pay attention to the condition of the lights in the room whether it lights up or not. This is certainly a waste of electricity when they leave the room without turning off the switch. Therefore, researchers propose an automation system that can save electricity from lighting. In designing the system there are two sensors used, namely Passive Infra Red (PIR) sensor and Light Dependent Resistror (LDR) sensor. PIR functions to detect the presence of human movements (objects) in the sensor work area, while the LDR sensor functions to detect the intensity of light around the room. The results of the system testing are that the PIR sensor works well around ± 2 minutes after the device is activated and the LDR Sensor will continuously measure the value of light intensity then turn on and off the light according to the programmed</jats:p

Journalist Philosophy: Binding the Norms of Islamic Law

Journalism is related to diaries that are published to the public and published in a certain way. Muslim journalism also breathes prophetic journalism, a form of journalism that not only reports news and problems in a complete, clear, honest, and actual way, but also provides interpretations and directions for change. ,transformation, based on the ethical and prophetic ideals of Islam. He became a journalism that consciously and responsibly contained the values and love of Islam. The philosophy of a journalist who is Muslim, ideally as a continuation of the Prophet's treatise is seen as an important study in today's information age. This is based on the view that the journalist is a teacher from the information society. then becomes important information that is absorbed by the public through the mass media. Because of his strategic position, he can become a benevolent spreader in the community through his mass media.</jats:p

Prototipe Sistem Computer Based Test dengan Pengacakan Soal Menggunakan Metode Fisher-Yates Shuffle

Evaluasi pendidikan di Sekolah Menengah Kejuruan Negeri 2 Depok seperti Ulangan Harian, Ulangan Tengah Semester, Ulangan Akhir Semester, dan Ujian Sekolah Berstandar Nasional belum terkomputerisasi. Evaluasi pendidikan yang belum terkomputerisasi ini mengakibatkan perlunya biaya untuk penggandaan soal dan waktu untuk proses koreksi jawaban. Oleh karena itu, solusi untuk menjawab masalah tersebut adalah pembuatan sebuah sistem terkomputerisasi untuk melakukan evaluasi pendidikan atau sering disebut sebagai computer-based test (CBT). Penelitian ini bertujuan untuk membuat sistem CBT di SMKN 2 Depok, sesuai dengan rencana pihak sekolah yang ingin merapkan sistem CBT pada evaluasi pendidikan. Penelitian ini menggunakan metode Fisher-Yates shuffle (FYS) untuk melakukan pengacakan soal. Metode pengembangan sistem yang digunakan adalah Waterfall. Alat yang digunakan dalam pembuatan CBT yaitu PHP, JavaScript, Bootstrap dan MySQL. Percobaan pada sistem CBT dilakukan dengan mengacak soal ujian yang terdiri atas 30 soal. Pengacakan soal dilakukan sebanyak 40 kali. Pengacakan soal yang dilakukan berhasil dengan baik, karena tidak terdapat urutan soal yang sama. Pengujian sistem dilakukan menggunakan metode black box. Hasil pengujian sistem menunjukan bahwa fungsional sistem sudah 100% berjalan dengan baik.</jats:p

Rekonfigurasi Jaringan Menggunakan Binary Particle Swarm Optimization (BPSO) Pada Penyulang Suryagraha

A radial distribution electrical network at a certain distance will have a large voltage loss due to conductive losses, especially at the endpoint. The tip voltage is determined by the distance of the distribution and the amount of load. The form of configuration also affects the amount of power loss and voltage loss. So that a good configuration is needed in order to obtain good efficiency. Reconfiguration of the distribution network is used to reset the network configuration form by opening and closing switches on the distribution network. Reconfiguration is expected to reduce power losses and improve distribution system reliability. Many feeders and buses on the network if calculated manually will be difficult and require a very long time. So it is necessary to solve problems using program assistance. In this case, use Particle Swarm Optimization (PSO). Particle Swarm Optimization (PSO) algorithm based on the behavior of a herd of insects, such as ants, termites, bees, or birds. BPSO is a development of the PSO algorithm designed to solve the optimization problem in a discrete combination, where the particle takes the value of binary vectors with length n and speed which is defined as the probability of bits to reach value 1. The results show a significant reduction in losses.</jats:p

History Ideas from Heritage of Building Sites Negeri Malayu Padang Kingdom in Tebing Tinggi

Historical and archaeological heritage for religious purposes, especially in the area. The conservation of the cultural heritage of the Padang Malay Kingdom in Tebing Tinggi requires the role of various parties such as the city government, cultural observers, academics and community participation in a social movement that loves local architecture to foster a sense of pride in the local artifacts that still exist. Therefore, this study describes the meaning of the idea as well as the government's attention from the legacy of the Malay Kingdom of Padang, Tebing Tinggi City. By using research methodology Interpretation is an effort to achieve a correct understanding of facts, data and symptoms. Using the theory of cultural areas (Trancik, 1986), namely an integrated area is an area consisting of elements physically having an orderly structure, normally paying attention to actors, cultural context, and roots, and functionally having an integrated network. The integration components in the aspect of norms describe cultural values and behavior of taste, creativity, and initiative.</jats:p
