Abstract

ABSTRACT Ginger plant (Zingiber officinale) has long been known and developed well in Indonesia. The ginger plant is a member of the Zingiberaceae (findings), which is a rhizome plant that is very well-known as a spice and as a medicinal ingredient. The ginger processing process is currently still using the traditional system or manually. So that the process of grating and squeezing ginger becomes easier and does not need too much effort. So it is necessary to design a machine that helps the process of grating and squeezing ginger. The design of the ginger belly and squeezer machine has 4 stages, namely planning, conceptualizing, designing, and completing. This ginger grater and squeezer is equipped with a process of dispensing without lifting the container/cauldron. The process of squeezing ginger juice or water with this machine will produce ginger juice, in 8 minutes the machine is able to process 2 kg of ginger with 1.4 liters of pure ginger juice / water. Keywords: ginger plant, grater, squeezer.

Abstract

AISI 4140 material is low-alloy steel that is widely used in its applications, which can be seen in automotive axle components. Based on these applications, it can be seen that AISI 4140 material is widely used in components that require high durability and hardness. The use of AISI 4140 in the mining industry is as a sleeve for the crusher unit drawbar. The sleeve material must go through a production process in the form of turning until it reaches the required dimensions. Case components must be durable and strong (with a long life) so that they do not hinder the production process in a company such as a coal company. Planning and using equipment and choosing the right materials can minimize production costs and speed up processes. This method can save production costs because it can reduce the 800 bushels per year needed in the mining area. This study aims to determine the factors that affect the performance of the case to increase the work efficiency of the crushing unit and reduce downtime due to damage to the case.

Abstract

The maximum stress theory states that failure occurs when the maximum principal stress in a component reaches the maximum stress value at the yield point. This theory is used to predict the failure of brittle materials. However, in an elastic body that is subjected to a three-dimensional load, complex stresses are created where each point of the body has stresses acting in different directions. Pineapple fruit cutting and peeling machines certainly have a power amount that can cause the resistance of the machine frame to be disrupted during operation. The purpose of this study is to design the frame of the pineapple cutting and peeling machine so that it is able to withstand the workload and the durability of the frame can be maintained, such as by making the design of the frame structure, assigning materials, determining constraints and loading, and other things that are deemed necessary in fulfilling the research objectives. This study uses experimental methods and literature. The literature method consists of the researcher using supporting theory from previous studies in such a way that the research is important from the point of view of the person being studied. The experimental method consists of researchers conducting direct experiments by designing research tools. The frame structure of this pineapple peeling and cutting machine has a length of 1000 mm, a width of 662 mm, and a height of 1000 mm. At the same time, the machine body is 400 mm long, 370 mm wide, and 2000 mm high. Holocron is used as the body material, with a thickness of 3 mm, specified at the time of modeling for each part to be manufactured.

Abstract

In many workplaces, we frequently see people manually transporting products. Many workers who use this trolley complain about back pain, lower back sprains, shoulders, and leg injuries, which leads to accidents and lost productivity. The goal of this study is to redesign the aluminum 6061 material frame of the ITNY Manufacturing Laboratory goods transport trolley in order to reduce issues with the regular and periodic maintenance and repainting. The loading ranges are 10000N, 20000N, 30000N, 40000N, 50000N, 60000N, 70000N, 80000N, and 90000N. The approach is the finite element method. According to the trolley simulation findings, the maximum von Mises stress value increases from 81.43 MPa at 50000N to 60000N loading. The largest increase in deformation occurred at a loading difference of 2.8527mm between 50000N and 60000N. The loading simulation from 10000N to 20000N, which had a safety factor value of 3.806, saw the biggest drop. The trolley's proposed design, made of 6061 aluminum, is capable of withstanding loads up to 30000 N

Abstract

PT Garam has a construction capacity of 10 tph, but currently, of the 4 packaging machine lines that are running, only 1 machine line is running. This is a challenge for PT Garam to use the utilization of the 10 tph capacity design. Currently, the factory only has a utilization rate of 47% and an effective utilization rate of only 15.98%. With this research, it will be obtained related to what factors influence the building capacity of 10 tph not being utilized properly. To find out these factors, a CIPP (Context, Input, Process, Product) evaluation was carried out. Using this CIPP evaluation can improve a program and make a decision. Context evaluation has a suitability level of 71.11% because of the 4 machine lines only 1 machine is utilized. The input evaluation has a conformity level of 65.33% because the fine packaged product does not yet have a packaging distribution permit. Process evaluation has a suitability level of 53.33% because the level of machine damage that often occurs results in low utilization. Product evaluation has a conformity level of 74.44% because the grain of the rough product packaging does not match the specifications. Overall the suitability of the CIPP evaluation has a conformity of 66.06%, of this figure the factory is still in the criteria according to the development design.

Abstract

Caliper is a part of a motorcycle, especially in the braking system, which functions as a brake pad suppressor to press the disc brake so that the motorcycle can stop or slow down according to its needs. Currently, the replacement of motorcycle calipers, especially on motorcycles that have a cubication of 250cc, is becoming a necessity among 250cc motorcycle owners. Replacing a motorcycle caliper requires a supporting part as a holder as well as a caliper holder or commonly called a caliper bracket. The caliper bracket is needed because the caliper to be installed has a larger shape and size when compared to the standard motorcycle caliper, so a caliper bracket that fits its size is needed. The bracket caliper products that are currently circulating have several shortcomings, such as the inaccuracy of the bracket, the difficulty of getting bracket products, and the ever-changing price. Therefore, this study aims to design a bracket caliper independently using CNC machine and accompanied by modification of the variable size using the VDI 2221 method. The modified component points are part of the caliper bracket. The characteristics of this method have 4 phases, namely, the description of the design task of the bracket caliper, the design of the design concept, the design of the product form, and the description of the details

Abstract

Availability of water is a major problem in several regions in Indonesia. There are several areas, especially in Gondosuli Village, Probolinggo, which can only maximize water use during the rainy season. In addition, water has an important role for the people, most of whom work as farmers. Water is one of the main factors affecting the amount of production of agricultural land and fisheries. This problem requires the availability of sustainable water, so that it can meet daily production needs. Therefore it is necessary to use a hydram pump that can work with the help of solar power without using electricity. The working principle of the hydram pump is to convert the kinetic energy of the water flow into dynamic pressure, and as a result a water hammer is created to create high pressure in the air pipe. With the design and construction of the Hydraulic Ram Pump System, it is hoped that it can address the availability of water in a sustainable manner, so that production in agriculture and fisheries can be stable and even increase.

Abstract

Indonesia is an industrial country that uses a lot of shafts as one of the important components in the production process. The shaft is one part of the rotating machine element whose function is to transmit power from one place to another. Shaft damage is one of the problems that often occurs, especially in the maintenance process that is not carried out according to factory standards or is not orderly in carrying out engine maintenance. The process of changing the shaft is expensive and the new material is sometimes not up to factory standards. Moving on from these problems, the author will design a shaft straightening machine with a rotation system. Previous research conducted by Juan Zhou designed a hexagonal axis straightening machine, but the hexagonal model still has a number of errors in its operation. The shaft straightening machine with the rotation method is expected to minimize errors and improve the shaft with better physical and mechanical properties after going through the heat treatment process with a rotation system
