Abstract

Metal cutting is the stage of processing profile raw materials and steel plates according to the cut marks that have been set in the marking process. One of the metal cutting techniques is to use oxy acetylene welding where the cutting occurs due to the reaction of oxygen and steel. Oxy acetylene welding is a manual cutting and welding process, in which the surfaces to be joined are heated until melted by the flame of acetylene gas, namely burning C₂H₂ with O₂ with filler metal or without filler metal where the joining process is without pressure. Besides for welding purposes (connection), oxy acetylene welding can also be used as preheating, brazing, cutting and hard facing. In the process of cutting iron pipes using oxy acetylene welding manually, the problem that is often found is the results of uneven and not straight cuts. This causes a leveling process to be needed on the edges that are cut so that they are flat and straight. In this research, a pipe cutting machine with oxy acetylene welding has been made which aims to produce straight, smooth, and even pipe cutting. The pipe cutting machine that has been made can produce flat, smooth, and straight iron pipe cuts on iron pipes with a diameter of 4.5 inches, 3.5 inches and 3 inches with a cutting time of 32 seconds, a motor wave rotation speed of 5.8 Hz, and a cut tolerance of ± 3 mm.

Abstract

Cryptocurrency is a virtual currency based on block chain. Yet, some countries forbid it as a means of payment in transactions. It can only be used as diversification in investment. In fact, cryptocurrency is a liquid asset even though it fluctuates. In Islam, there are different views whether cryptocurrency can be assets or can be zakah, infaq, sadaqah, and waqf. The object of this study is to answer whether the crypto can be al-amwal azzakawiyah or something that can be zakah and waqf which can be maslahah for the society. Another purpose of this research is to enlighten about zakah and waqf managers on what cryptocurrency is for. The theory used is the theory of zakah and waqf in Islam. This is a qualitative study with a conceptual approach and an Islamic law approach. The result of this research is that cryptocurrency can be said as wealth or al-maal that can be zakah, infaq, and waqf because it has fulfilled several requirements to be classified as wealth or al-maal in Islam.  Zakah calculation of crypto currency must exceed the nisab 2,5% equivalent to 85 grams of gold, the owned can already be an object of zakah.

Abstract

Indonesia is an agricultural country where the majority of the population is farming. Farmers in Indonesia still use many traditional methods in processing agricultural land such as using hoes. In previous studies, a soil bulking machine was made with a slope of the plow blade angle of 90 ° and obtained less than optimal loose results. The influencing factor is that the angle of the hoe eye is not large, therefore the manufacture of a soil bulking machine is carried out using a hoe-shaped plow with the slope of the corner of the hoe eye enlarged to 110 °. The soil bulking machine uses 30 hoe-shaped plowshares with a hoe blade height of 10 cm, a width of 10 cm and a hoe tip thickness of 6 mm. The type of soil that can be plowed by this soil bulking machine is soil that has been cultivated on agricultural land. The test was conducted on an area of 28 m2. In the first experiment, it took an average of 18.78 seconds with an average pirated depth of 9.76 cm. In the second experiment, it took an average of 16.91 seconds with an average pirated depth of 9.30 cm. In the third experiment, it took an average of 19.24 seconds with an average pirated depth of 11.26 cm. The result of soil loosening with an average productivity of 1.53 m2 / second with an average depth of 10.10 cm.

Abstract

The negative impact of spreading hate speech on social media has prompted various parties to intervene. Computer science researchers have conducted experiments to find solutions for automated intervention by applying artificial intelligence, such as machine learning and deep learning. The fulfillment of the theory of truth makes the machine learning paradigm considered by scientists to solve problems. However, the increasing size of social media data has shifted its paradigm to deep learning. Deep learning becomes a new normal science after completing the task of classifying hate speech well on a large amount of data. However, any approach will be an anomaly when it cannot complete the task. The accessibility of research resources makes it easier for researchers to determine the nature of their experiments, whether scientific or pseudo-science.

Abstract

Jurusan Teknik Mesin pada tahun 2024 telah melaksanakan melaksanakan pengabdian kepada masyarakat di desa Pergam Kecamatan Airgegas Kabupaten Bangka Selatan. Mitra pengabdian adalah Pemberdayaan Kesejahteraan Keluarga (PKK) Desa Pergam. Untuk lanjutan pengabdian tahun 2025 berdasarkan hasil wawancara dengan bapak Sukardi (kepala desa pergam) dan Ibu Nenih Sumarni (ketua PKK desa Pergam) adalah tentang pembuatan kompos. Saat ini dibutuhkan alat atau mesin untuk membantu dalam produksi kompos. Kendala saat ini yang dialami mitra yaitu pencacahan bahan-bahan untuk kompos masih dilakukan secara tradisional menggunakan pisau atau parang. Selain itu pengadukan untuk mencampur bahan kompos masih dilakukan secara manual sehingga memerlukan tenaga yang besar dan waktu yang cukup lama. untuk mencacah bahan kompos bisanya diperlukan waktu berkisar 30 menit sehingga tidak efektif. Tim pengabdian berencana membantu mitra dengan menyiapkan mesin pencacah bahan organik. Mesin yang akan dihibahkan merupakan mesin dari hasil penelitian mahasiswa program studi Teknik Mesin. Mesin tersebut diharapkan dapat digunakan untuk mencacah bahan-bahan organik untuk bahan pembuatan pupuk kompos. Melalui proposal pengabdian ini, tim pengabdian akan membuat dan menyerahkan mesin pencacah sampah organik ke mitra, melakukan pendampingan penggunaan mesin, dan sosialisasi cara membuat pupuk kompos.
