Abstract

Repair and maintenance activities aim to increase the functional capability of a system or tool used in production. At PT. Lintech Duta Pratama (PT. LDP), overhead crane is used as a means of moving materials and finished goods. This tool operates to transport materials and finished goods continuously for ± 7 hours per day for 5 working days a week. However, maintenance actions have not been carried out optimally due to a lack of manpower/workers. Thus resulting in delays in the implementation of maintenance activities and affect the completion of production. Against this background, failure identification was carried out using the Failure Mode and Effect Analysis (FMEA) method on the 12.5T overhead crane. With this method the results obtained by filling in the FMEA Worksheet showed that there were 13 components that had the highest risk level value, with 26 failure modes from whole component. The highest RPN value is for the MCB/main power supply component with a value of 209, while the lowest is for the hoisting hook component with a value of 7. So that this component can be considered by the maintenance team and related parties in the company when carrying out maintenance activities on the overhead crane equipment

Abstract

Geopolymers are solid inorganic polymers produced from a chemical reaction called geopolymerization between an alkaline solution and an aluminosilicate source. Aluminosilicate materials are composed of silica and alumina atoms. To activate the polymerization reaction between silica (Si) and alumina (Al) an activator solution is needed. Many studies have used geopolymers because they are known for their fire retardant properties. With the added ingredients of Sodium Borax Tetra Hydrate and Diammonium Phosphate, these two added ingredients have the potential to be fire retardants. To determine the effect of the addition of geopolymer additives, pressure testing was carried out on the specimens before and after being burned at 900 oC for 1 hour. In this study, using raw materials metakaolin and silica fume of 80:20 (%) and a constant KOH pellet and water glass activator solution. As well as varying the additives, namely 1% Sodium Borax Tetra Hydrate, 1% Diammonium Phosphate and specimens without additives. The results of the compression test showed that the composition that had the best compressive strength before combustion was the addition of 1% Diammonium Phosphate, which was 24.4 MPa. While the specimens after burning which have the highest compressive strength value are the specimens without additives, namely 9.5 MPa.

Abstract

Companies engaged in heavy equipment, both distributors and heavy equipment maintenance processes, generally have warehouses in the storage of spare parts. UT Surabaya has many support points that result in the accumulation of spare parts storage to eat other areas. As a result, the company's workflow is hampered due to improper placement of spareparts in the proper area which results in damage to spare parts. One method that can solve this problem is the Systematic Layout Planning method. This method has a detailed procedure for arranging layouts so that it can bring up more than one alternative layout. In addition, the Class Based Storage method is also used as a design and calculation of racks to design a warehousing system that is aligned within the company. The use of this method resulted in the proposed layout material handling cost, namely the total initial layout OMH was Rp759,235.74, - while the proposed layout OMH was Rp646,000.06,-,. In the comparison of OMH, it was found that the cost decreased by Rp113,235.68,- per day. So the new layout is able to increase the efficiency of mileage material handling costs.

Abstract

The potential of the sea in Indonesia is commonly used for the utilization of renewable energy from sea waves. One of the efforts to utilize energy, among others, is using a power plant by utilizing seawater wave power energy. So there is a need for ideas and design concepts about mechanical transmission of power plants powered by more effective seawater waves. This study aims to analyze the design of a cylindrical float type Marine Wave Power Plant (PLTG). This discussion focuses on variations in the height of a device, arm length, and buoy diameter. Where when the amplitude and frequency of water waves provide up and down movements of the cylindrical buoy. Then the torque will be generated from the main shaft which has a one way bearing which aims to rotate in the same direction, then forwarded to rotate the generator which will produce electrical energy. The largest power value is obtained in the variation of tool height (Y = 0.5 m), arm length (Pl = 3 meters), and diameter (ø = 0.4 m) which is 599.596 watts. Then the smallest power value in the variation of tool height (Y = 1.5 m), arm length (Pl = 2 m) and buoy diameter (ø = 0.6 m) which is 291.334 watts.
