Abstract

Machine dryers often have problems causing the temperature to not be hot, whether it's due to engine part damage or other things. As a result of these constraints the work was delayed. What happens is that the work is not optimal and results in losses. The goal is to reduce excess costs, simplify the work process for operators and also help business owners minimize sudden damage that results in sub-optimal performance. Preventive Maintenance is a maintenance and maintenance activity carried out to prevent the occurrence of unexpected damage symptoms and find conditions or circumstances that can cause production facilities to experience damage during the production process. In the ISMO method, there are several terms and stages that must be carried out to produce a scheduling system and determine cost estimates for the next few years. the results obtained are a manual checklist, soup for each machine and also a maintenance schedule for six and a half years and from the first six months of experimentation there has been a reduction in costs. Implementation of Preventive Maintenance scheduling on Duel laundry has been successful. From the comparison of time for six months. For development, research can be done by determining how many pieces of clothing will be processed to make it easier for workers to measure the capacity of the machine during operation.

Abstract

In the welding process, the swing of the electrode is very influential on the mechanical properties of the weld. The purpose of this study was to determine the hardness value in the HAZ area of ​​AISI 1045 steel due to differences in SMAW welding electrode swing. The method in this study uses experimental research methods, namely describing comparisons of treated specimens using the help of the Microsoft Excel application. The material used in this study was AISI 1045 medium carbon steel which was welded using SMAW welding with variations of zig-zag, circular and C swing electrodes with 1G position. The results of this study prove that the electrode swing has a significant effect on the hardness value. It can be seen that the test material with a circular swing pattern has a higher value than the zigzag and C swing patterns. This is shown by testing the hardness test in the HAZ area where the circular swing pattern gets average. -the highest average hardness value is 23.47 HRC. Meanwhile, the lowest average hardness value is in the C swing pattern of 20.46 HRC. Electrode swing has an influence on the hardness value. The circular swing pattern has a higher value than the zigzag and C swing patterns.

Abstract

The bimetallic welding process is a welding process that connects two different types of metal. This study aims to determine the effect of the E309-16 electrode on the connection of two materials using smaw welding on tensile strength. The materials used were carbon steel AISI 1045 and stainless steel 304. This study used an experimental method with a penetration and filling welding process with a 60° V seam using an E309-16 electrode. The shape of the specimens in this study used the ASTM E8 standard. From the results of the tensile test research conducted, the E309-16 electrode has an influence on the bimetallic welding process on AISI 1045 carbon steel and 304 stainless steelwith a resulting tensile strength of 58.01 Kg/mm – 68.48 Kg/mm, yield strength that is produced by 35.97 Kg/mm – 37.12 Kg/mm, the resulting strain value was 12.50% - 43.00% and was able to withstand a given tensile load of 6450 Kg – 7900 Kg. and the bimetallic welding process using the E309-16 electrode has a more binding effect on the 304 stainless steel material, this is evidenced by the broken specimens in the weld area and the lower carbon content of 304 stainless steel with a carbon content of 0.042% compared to AISI steel material 1045 which has a carbon content of 0.42%.

Abstract

Lokan mussels (Geloina erosa) live at the bottom of sandy and muddy waters. Lokan shell waste is found on many Indonesian beaches and is left unattended by the surrounding community, so a new breakthrough is made to add value to the use of the shell. this study aims to convert waste into materials that can increase pH in water, because there are calcium carbonate (CaCO3) compounds that are useful in the adsorption process. Adsorption is the process of absorbing substances or content such as iron metal (Fe). The pores on the surface of the shell can carry out the adsorption process using a physical method, namely heating at 250 oC and 350 oC to open the pores on the surface. The result of this test is that the shells of lokan shells made and then tested for Ph in water mixed with powder have an increase in value from 5.7 to 7.4 - 8.2. In elemental testing or (XRF) for the lokan shell itself there is the element CaO or Calcium oxide after heating.

Abstract

Lathe transverse slide jamming can disrupt the machining process and reduce the quality of work results, on the Ajax 200 E lathe used, damage was found such as a jammed cross slide through the Root Cause Failure Analysis (RFCA) approach and the 5 Why’s method, finishing that the main cause of damage was that the Cross Screw was bent which caused the slide movement to become jerky. After straightening the Cross Screw, the problem was resolved. Observations showed that the slide movement returned to normal. This study emphasizes the importance of technical documentation and work procedures in preventing further damage.

Abstract

This study aims to repair the cooling and braking systems of the DoAll LT 13 lathe at the Polman Babel Workshop by applying the Corrective Maintenance method. This lathe has been in operation for 28 years and has experienced failures in both the cooling and braking systems, resulting in decreased performance. The repair process began with problem identification using the 5 Why method to find the root causes of the failures. The analysis revealed that the main issues were a non-functional electric motor and the absence of caliper and master cylinder components. The repair steps included replacing the electric motor, installing the cooling hose and valve, and modifying the braking system using spare parts from a Panther vehicle. Testing after the repairs showed that both the cooling and braking systems were functioning properly. This study concludes that the application of Corrective Maintenance is effective in restoring the functionality of the DoAll LT 13 lathe and ensuring the availability of the machine for student practical activities.
