Abstract

Research in the pertinent subject is a key component in the advancement of science. This was carried out in an effort to address a number of issues and broaden the body of knowledge in this scientific domain. In Indonesia, academics, practitioners, and researchers hold seminars hosted by government and non-government organizations with the goal of giving them a platform to enhance scientific articles by offering corrections to their findings. Papers, theses, dissertations, and scientific journals were the primary sources of information for earlier bibliometric scholars. This is done in order to observe information utilization, gathering, obsolescence, knowledge mapping, etc. The background information for this research is as follows, based on the material above: first, there is no knowledge mapping to identify trends in research topics, particularly in computer science-related scientific articles, particularly in the Department of Computer Engineering and Informatics at Medan State Polytechnic. The problem to be researched will be formulated using numerical measuring instruments based on trends in research topics and bibliometric studies of scientific articles in proceedings in the field of computer and information science at seminars and conferences in Indonesia.

Abstract

To help businesses or organizations manage their inventory of goods more effectively and efficiently, information management is crucial. Businesses can monitor and manage the amount of goods on hand, prevent shortages or excess inventory, and streamline the shipping and receiving process with effective information management. Instead of utilizing a technology-based (computer-based) management system, the equipment management system in the Tool Crib of the POLMED mechanical engineering workshop is still conventional. wherein equipment borrowed by students or other stakeholders is not information management-based and is instead still documented in a form. Therefore, it is impossible to effectively control the quantity, quality, and identity of the tools that are borrowed. And the fact that the equipment is frequently misplaced or lost presents a challenge. The Waterfall method is the approach devised during the research. Software development follows a methodical design called the Waterfall Method. This study used quantitative descriptive research as its methodology. A method or approach to solving research problems in quantitative descriptive research involves characterizing the state of the object under investigation a person, organization, factory, etc. as it is based on real facts at the moment the research was conducted or is being conducted.

Abstract

Islam mengatur tentang tatacara ber-mu’amalah sebagai sarana hablun minnan nas dengan menerapkan akad yang sesuai dalam setiap kegiatan yang dilakukan. Pinjam-meminjam barang adalah hal yang umum dalam ber-mu’amalah, namun dalam hal pinjam-meminjam pada area publik tidak jelas apa akad yang digunakan sehingga tidak diketahui batasan-batasan tentang pinjam meminjam di area publik. Sehingga tujuan penulisan ini untuk mengetahui kedudukan hukum fiqh terhadap meminjam barang pada wilayah publik tanda akad sharih. Penelitian ini menggunakan metode penelitian kualitatif dengan analisis deskriptif berdasarkan kajian Pustaka secara umum. Dari hasil penelitian ditemukan meminjam barang tanpa akad sharih pada wilayah publik secara umum dapat dikatagorikan sebagai ariyah, dimana merupakan pinjam meminjam dengan tujuan tolong menolong, dimana musta’ir meminjam barang kepada mu’ir untuk diambil mamfaatnya, dan setelah selesai barang yang dipinjam haruslah dikembalikan, dimana akad dapat dilihat dari niat peminjam sebagai mu’ir kepada yang meminjam sebagai musta’ir.

Abstract

Penelitian ini merupakan hasil field research untuk menjawab pertanyaan bagaimana proses parsidua-duaon dalam hukum perkawinan adat Batak di desa Sigulang kota Padangsidempuan? Dan Bagaimana tinjauan Hukum Islam terhadap parsidua-duaon dalam hukum perkawinan adat Batak di desa Sigulang kota Padangsidempuan? Hasil penelitian menemukan bahwa dalam adat parisudua-duaon di desa Sigulang berarti anak masuk ke dalam kelompok kekerabatan (keturunan darah) bapak. Sehingga hak tanah, milik, nama, dan jabatan hanya dapat di warisi oleh garis keturunan laki-laki. Sehingga parsidua-duaon dalam sistem hukum adat Batak bertujuan untuk melanjutkan keturunan marga dan mendapatkan anak laki-laki yang sah, bila isteri tidak dapat melahirkan anak laki-laki.  Dalam proses parsidua-duaon (beristeri dua/poligami) setiap keluarga yang terlibat melakukan mufakat keluarga terlebih dahulu dengan menentukan beberapa peraturan yang bersama-sama disepakati seperti kesepakan keluarga suami kepada keluarga isteri untuk mendapatkan izin menikah lagi, dan izin kepada keluarga isteri yang akan dinikahi, serta kesepakatan lain yang bersama-sama dibuat untuk kebaikan antar keluarga. Jika ada yang melanggar kesepakatan yang telah dibuat maka akan dikenakan uhum (hukuman) biasanya dengan membayar sejumlah uang atau binatang ternak seperti kerbau.

Abstract

Abstrak: FIFO is an acronym for First In, First Out, an abstraction that deals with how to organize and manipulate data relative to time and priority. The FIFO (First In First Out) method is a method where the goods that were first entered will be issued first, while the goods that were last entered will be issued at a later date. So the first inventory recording is to record the goods/inventory that first entered UD. Karya Bersama is a business in the field of photocopying that is intended for all circles which provides photocopying, volume, and stationery services. The problem that exists is in making inventory reports of UD. Karya Bersama still uses manual methods and is not computerized so that there are reports of inventories that are inefficient, inaccurate and take a long time, this encourages to change the inventory system due to the impact experienced in the future results of reports that are not precise and efficient. The impact resulting from a computerized system can make it easier and faster to process data and get information quickly and efficiently. Kata kunci: First In First Out, UD.

Abstract

  Abstract                                                                          Based on article 22 of PP Number 9 of 1975, article 76 of Law Number 7 of 1989 and article 134 of Presidential Instruction Number 1 of 1991, Divorce (syiqaq) where disputes and quarrels are continuous must be proven by witness testimony, so The position of the witness is an important thing in deciding a divorce case. Witnesses who are present in court must materially see, hear and experience directly the legal events that occur, this must be in accordance with article 172 HIR/308 Rbg in conjunction with article 76 Law Number 7 of 1989. Meanwhile, in Islamic law, the position of deaf witnesses is that the majority of ulama seemed to have absolutely no tolerance for their opportunity to be witnesses. They agreed that hearing what the parties said and understanding what they meant was an absolute requirement for witnesses. The argument is because something that is the object of the witness is words. Law No.19/2011 about concerning ratification of the CRPD and the principle of Equality Before the Law also states the same thing, which does not differentiate between people in person. trial, while formally a deaf witness is not a mentally disabled witness, he just lacks hearing but can see and judge events well._________________________

Abstract

End mill cutter is a type of blade that is commonly used in the working practice of milling machines. Because it is easily dull, these blades need to be sharpened to obtain a good geometric shape of the cutting surface. At the mechanical engineering workshop of the Medan State Polytechnic, the sharpening process is carried out using an end mill cutter grinder machine. However, the quality of the honed results is still not good. This study aims to improve the quality of the sharpening results by modifying the grinding stone stand shaft on the sharpening machine. The method used is a technical experiment by changing the dimensions of the shaft and locking system so that the grinding stone rotation becomes more symmetrical and stable. Primary data were obtained by measuring the symmetry of the mounting shaft with the indicator dial and the cutting experiment on the workpiece. Data analysis was carried out by comparing data from the old shaft with the new modified shaft. Sharpening experiments were carried out on the end mill cutter Ø 20 mm and the results obtained were very good cut quality and symmetrical tests showed a result of 0.055; 0.04 ; 0.01 mm is still below the standard tolerance of 0.05 mm.
