Abstract

Community service (PkM) has been carried out regarding the use of chicken feed printing machines. The PkM place is in Pergam Village, Airgegas District, South Bangka Regency. The purpose of PkM is to increase the productivity of the Pergam village partner chicken farms. This program has been implemented before in other areas, because the program was successfully adopted in Pergam village. This service is a continuation of the 2021 service on the use of egg incubators. The success of the hatchery program through the egg incubator raises new problems related to feed availability. Currently, the price of feed is expensive, so farmers must look for alternatives to meet their feed needs. Service partners have limited funds to buy feed from the market. So the service team from the University of Bangka Belitung provided assistance in the form of a chicken feed printing machine. The implementation of the service has been carried out through four stages, including: The first stage, field observations and interviews with partners to record the problems faced by partners. The second stage, determine the focus and solution to the problem. The third stage is the implementation of service and assistance in the use of chicken feed printing machines, and the last is an evaluation of activities to record problems and the sustainability of the service program in the future. The service that has been carried out is by handing over two units of feed printing machines, assistance with supporting equipment for livestock and machinery. based on the results of interviews with partners, with a chicken feed printing machine can reduce feed costs by 50-60%.

Abstract

Pengeringan adalah proses perpindahan panas dan uap air secara simultan yang memerlukan energi panas untuk menguapkan kandungan air. Energi panas ini biasanya bisa didapatkan dari sinar matahari. Namun ketika musim penghujan, kondisi ini menghambat proses pengeringan yang memanfaatkan sinar matahari, sehingga proses pengeringan membutuhkan waktu yang cukup lama. Maka dari itu diperlukan suatu alat bantu yang dapat mengeringkan baju tanpa tergantung pada sumber panas dari pancaran sinar matahari. Alat pengering Baju adalah Alat yang digunakan untuk mengeringkan pakaian dengan energi panas buatan, salah satu penghasil panas buatan adalah elemen pemanas atau yang sering disebut dengan heater. Elemen pemanas buatan yang digunakan pada penelitian ini adalah Electric Heater. Electric Heater ini dilengkapi dengan kipas yang dapat menghasilkan suhu dalam ruangan hingga ± 52,3º C sehingga panas yang dihasilkan Electric Heater dapat mengubah air yang terkandung dalam pakaian menjadi uap air yang kemudian akan dilepas ke lingkungan dengan bantuan kipas. Berdasarkan hasil perhitungan dan pengujian, Kemampuan alat ini mampu menguapkan massa air rata-rata 535.8 gram/jam dan mesin ini mencapai titik optimumnya untuk jumlah pengeringan pakaian yang dapat dikeringkan sebanyak 6 baju.

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

Alignment is a technique used to maintain machine components that rotate or transfer power so they can operate as effectively as possible and prevent damage to other machine components from errors made during installation or maintenance. Alignment is a maintenance activity that is often carried out on machines in industry and machines within the Morowali Metal Industry Polytechnic, especially in the Mechanical Maintenance Engineering Study Program. Competency in the alignment of gears and bearings is very much needed for prospective mechanics in the industry. The purpose of making this tool is as a simulation tool for learning alignment to achieve straightness and centricity between two rotating shafts (drive and driven shaft) to prevent friction, vibration, and other problems that can reduce tool life and, of course, increase expenditure costs. for repair or replacement of heavy equipment. In the process of designing this alignment tool, a drive method is used in the form of a sprocket and chain, where the link between the drive motor and the shaft to be moved is the sprocket and chain method. This research serves to help produce a design by considering the user's perspective so that the design results can be useful effectively. From the test results, the gear alignment setting tool can function well with the help of an inverter so that motor rotation can be reduced and can be controlled according to the desired conditions. The previous alignment setting tool had an RPM: of 1450.8 and the alignment setting tool that was made had an RPM: of 1455.7 with a frequency of 50 Hz so it can be concluded that this tool can be used for practical work in machine repair and maintenance laboratories.
