Abstract

The development of science and technology and along with advances in the field of industry, especially in the field of machinery, various tools were created to simplify and increase human comfort in fulfilling their needs. The workpiece gripping mechanism on the sitting drill machine works by being controlled manually using a control lever, making it difficult for the operator to operate and making the processing time long. The author will conduct research on the design of workpiece gripping tools using a magnetic vise on a drilling machine. It is hoped that the design of this magnetic vise can reduce the work of an operator and can shorten the time of installing the workpiece so that it can increase the work productivity of the drilling machine, reduce operating costs and increase the work safety of an operator. From the results of the analysis of the design of the Magnetic Vise designer, it can be concluded that the circular magnetic field around the wire is 8100π x 10-4 Tesla, Resultant of Magnetic Induction in Parallel Wire B1 = 18 x 10-5 Tesla and B2 = 10.8 x 10 -5 Tesla, Resultant magnitude of magnetic induction Bp = 28.8 x 10-5 Tesla. The solenoid is a coilshaped wire with fairly tight turns and has a length of = 360 cm with a number of turns = 150, the magnitude of the magnetic induction at the end of the solenoid is different from the magnitude of the magnetic induction at the center of the solenoid. The magnitude of the magnetic induction at the center of the solenoid is 45 x 10-5 Tesla. larger than the solenoid tip by 11.25 x 10-5 Tesla.

Abstract

The industrial component of industrial equipment is required to have good quality. The elementsor components of a tool must be light but have strong and corrosion-resistant alloys. Testing ofthe materials to be used must be appropriate and in accordance with the needs. There are severalways, one of which is by using a torque testing machine and Finite Element Analysis (FEA). FiniteElement Method (FEM) or commonly called Finite Element Analysis (FEA), is a numericalprocedure that can be used to solve certain engineering problems. Modeling torsion test objectsusing the FEM with a moment 598.0635 N mm, - 598.0635 N mm with respect to vector Xcounterclockwise. The material used is ASTM A 36 with a mass of 0.0163569 kg and a volume of2083.94 mm^3, torsion test analysis using finite element-based software. Based on thesimulation results, it can be seen that the largest stress (maximum stress) occurs in the XZ vectorwith a value of 10.4783 MPa, while the smallest stress (minimum stress) occurs towards the YZvector with a value of 0.15986 MPa. The largest strain (maximum strain) occurred in vector XZwith a value of 0.000068123 ul, while the smallest strain (minimum strain) occurred in vector XXwith a value of 0.00000107672 ul. The safety factor obtained is 0.71, meaning that the value isless than equal to 1 which indicates that the test object is unable to accept the given load.

Abstract

During a pandemic like today, a very strong immune system is needed to maintain the body's resistance so that it is not easily exposed to disease. Strong immune power is produced from foods and beverages that contain good nutrition and nutrition for the health of the body. One of the drinks that can increase the body's immune power is Traditional Jamu which is well known to the Indonesian people, because Indonesia is very famous for its rich herbal ingredients that have many health benefits. There are so many kinds of herbs that can be found in our country that many foreigners even hunt, because the properties contained in herbs are needed for body health and are rarely found in other countries. This is an advantage for us Indonesian people, who clearly will have no trouble getting raw materials to mix herbal drinks. This is an opportunity for our society, so that they can develop traditional herbal drinks to be more modern and penetrate the global market. This of course requires touches of renewable technology, so it is hoped that traditional Indonesian herbal drinks can be marketed to the wider community and the biggest hope is to enter the international market. However, in reality, there are several obstacles faced by traditional herbal drink manufacturers. Among them is the resulting product has a short shelf life. For this reason, it is necessary to transfer the right processing and packaging technology so that the product shelf life is longer. The method used in this research is a touch of transfer of processing technology and packaging technology to extend the shelf life of the traditional herbal medicine industry in Majalengka, so as to improve product performance.
