Abstract

Banyaknya komponen dalam industri manufaktur memerlukan penggunaan teknik pengelasan yang efektif dan efisien. Pengelasan gesekan adalah metode penyambungan benda padat di mana laju rotasi satu benda kerja digabungkan dengan laju rotasi ujung benda kerja yang lain. Durasi gesekan, kecepatan rotasi, dan tekanan merupakan variabel penting dalam pengelasan gesekan karena mempengaruhi kualitas dan hasil proses. Material yang digunakan dalam penelitian ini adalah baja St.60. Parameter yang digunakan dalam penelitian ini adalah kecepatan putar 2300 rpm, waktu gesekan 60 detik dan tekanan 70 Psi. Dengan memvariasikan pendingin. Setelah pengelasan gesekan, benda kerja dipadamkan dengan minyak pendingin, air garam, udara dan air. Untuk mengetahui sifat mekanik dari hasil pengelasan ini dilakukan pengujian kekerasan dan pengujian tarik. Dari hasil penelitian ini diketahui bahwa variasi cairan pendingin mempengaruhi metode las gesekan. Hasil kekerasan tertinggi daerah sambungan sebesar 170 HB terdapat pada variasi fluida pendingin air asin, kekerasan terendah pada daerah sambungan sebesar 112,33 HB terdapat pada variasi fluida pendingin udara. Hasil kekuatan tarik tertinggi sebesar 517,82 N/mm² terdapat pada variasi pendingin air asin. sedangkan kekuatan tarik terendah sebesar 291,70 N/mm² terdapat pada variasi fluida pendingin air. Many components in the manufacturing industry necessitate the use of effective and efficient welding techniques. Friction welding is a method of joining solid objects in which the rotation rate of one workpiece is combined with the rotation rate of the other end of the workpiece. Friction duration, rotational speed, and pressure are all critical variables in friction welding because they affect the quality and outcome of the process. The material used in this research is St.60 steel. The parameters used in this study are the rotational speed of 2300 rpm, the friction time of 60 seconds and the pressure of 70 Psi. By varying the coolant. After friction welding , the workpiece is quenched with coolant oil, salt water, air and water. To determine the mechanical properties of this welding result, this research is carried out by testing the hardness and tensile testing. From the results of this study, it is known that the variation of the coolant affects the friction welding method. The result of the highest hardness of the connection area of 170 HB is found in the variation of the salt water cooling fluid, the lowest hardness of the connection area of 112.33 HB is found in the variation of the air cooling fluid. The result of the highest tensile strength of 517.82 N/mm² was found in the variation of the salt water coolant. while the lowest tensile strength of 291.70 N/mm² was found in the variation of the water cooling fluid.

Abstract

Pengambilan keputusan adalah tindakan pemilihan alternatif. Hal ini berkaian dengan fungsi manajemen. Menurut Herbert A. Simon, ahli teori keputusan dan organisasi mengkonseptualisasikan tiga tahap utama dalam proses, pengambilan keputusan, Aktivitas inteligens, Aktivitas desain, Aktivitas memilih. Tahap selanjutnya ini merupakan pilihan sebenarnya-memilih tindakan tertentu dari yang tersedia. Sedangkan Mintzberg a koleganya mengemukakan tentang tahap tahap pengambilan keputusan, yaitu: Tahap identifikasi, Tahap pengembangan, dan Tahap seleksi. Pengambilan Keputusan dalam perilaku organisasi menunjukkan rasional. Rasionalisasi yang paling sering digunakan dalam pengambilan keputusan adalah bahwa hal tersebut merupakan rencana tujuan. Model Perilaku Pengambilan Keputusan, antara lain: Model Rasionalitas Ekonomi, Teknik Rasional Modern: ABC, EVA, dan MVA, Model Sosial, dalam bentuk Rasionalitas yang terbatas dari Simon, dan Heulistik Penilaian dan Model Bias. Gaya Pengambilan Keputusan, antara lain: Gaya Direktif, Gaya Analitik, Gaya Konseptual Gaya Perilaku. Gaya tersebut membantu menjelaskan mengapa manajer yang berbeda membuat keputusan yang berbeda setelah mengevaluasi informasi yang sama. Ada beberapa teknik pengambilan keputusan, antara lain: Teknik Partisipatif, Teknik Keputusan Kelompok, metode teknik dan teknik Kelompok Nominal Saran.

Abstract

Tujuan perancangan dan pembuatan alat smart locker berbasis internet of things untuk memberikan rasa aman terhadap barang titipan bagi pengguna dan pengelola, serta memberikan informasi bagi pengelola tentang pendapatan secara real time. Alat ini di rancang dengan menggunakan metode waterfall yaitu meliputi analisis kebutuhan, perencanaan perangkat keras, perangkat lunak dan testing. Pengendali utama sistem menggunakan arduino dan modul ESP8266, dilengkapi dengan rangkaian input, berupa sensor getar SW420, Radio Frequency Identification (RFID-Rc522), Limit Switch. Rangkaian output dibentuk dari komponen buzzer dan selenoid door lock. Komunikasi sistem dengan pengguna menggunakan aplikasi telegram untuk mendapatkan pemberitahuan tentang keamanan barang titipan. Penginputan data oleh admin dan informasi pendapatan bagi pengelola menggunakan website. Hasil pengujian alat diperoleh dengan memberikan getaran pada pintu locker, sistem mengirim notifikasi sebagai tanda bahaya kepada pengguna dan pengelola. Pengujian software, oleh admin dengan memasukan data ID telegram pengguna, maka di website akan terlihat pertambahan jumlah pengguna locker dan pendapatan secara real time bagi pengelola.Kata kunci : Internet Of Things, sensor getar SW420, RFID-Rc522, Limit Switch, Website The aim of designing and manufacturing an internet of things-based smart locker device is to provide a sense of security for entrusted goods for users and managers, as well as provide information for managers about income in real time.

Abstract

Learning is an activity designed to create a person's state of being able to seek knowledge well. Learning is very important because every human being needs to study religion. Studying Islam cannot be separated from referring to the hadith books of the Prophet Muhammad SAW. In Madrasah Aliyah Miftahul Huda Tanjunganom, for example, yellow books such as Bulughul Maram are taught to students. This observation aims to describe how the study of the book of Bulughul Maram at MA Miftahul Huda Tanjunganom can improve students' understanding of fiqh. This research is included in the category of field research with a qualitative approach and descriptive methods. Data was collected through interviews, observations, and documentation with informants such as Madrasah Heads, teachers, and students. The results of the study resulted in students' understanding of fiqh increasing after participating in the study of this book, as evidenced by tests that showed significant changes. Although learning is going well, challenges arise from the lack of interest in learning students. However, thanks to the hard work of teachers, this challenge was successfully overcome and students' understanding of fiqh increased after participating in the study of the book of Bulughul Maram.
