Abstract

The mining industry, especially coal mining, has a transportation and delivery process from one location to another. In the transportation process, there are usually obstacles caused by damage to components that can hinder the delivery process. One of the transportation equipment that often fails is the Apron Feeder. The work process that works continuously and repeated loading can damage the components on the Apron Feeder, one of the components that are often damaged is the Bushing. This study aims to analyze and determine the causes of damage to the Apron Feeder Bushing. The method of this research is by looking at the microstructure of the material, the hardness value of the material, seeing surface defects using a dye penetrant. With the results obtained, namely the number of defects in the form of scratches and porosity in good Bushings which can be the cause of damage to the Bushings and on damaged Bushings, there is martensite which shows that the Bushing is deformed and brittle which results in operations which can be the cause of damage to the Bushing and the results of XRF testing ( X-Ray Fluorescence) the composition of the material on the Bushing is made of AISI 4140 where there is a difference in composition in the original specification of the material, namely SCM 415.

Abstract

The use of an Apron feeder with a carrying capacity of 90 tons with a motor with a power of 55 KW and engine speed of 1500 RPM as a container for coal unloading results in train cars and then distributed to a belt conveyor for 24 hours. Based on Standard Operating Procedures (SOP), the apron feeder can accommodate 8 train carriages for 120 minutes of unloading coal. This process initiates the possibility of fatigue in the Apron feeder component, namely the chain link. This study aims to determine the cause of chain link damage in terms of micro structure and strength to the value of hardness by using chain link analysis samples from PT. Acid Hill. Metallographic testing showed the presence of a banded structure in the new sample and the presence of a martensite phase in the damaged sample material, causing the material to become stronger but brittle.

Abstract

This research was carried out aiming to see the temperature around the occurrence of natural disasters using temperature and humidity sensors that were used as robot eyes, and bluetooth sensors were used to control the robot car by connecting with android as a controller. The benefit of this research is to make it easier for the SAR team to search for victims of natural disasters and make time more efficient and reduce the risk of accidents for the SAR team. The research method used is qualitative with testing documentation techniques carried out and recording the data obtained. From the results of this study, it was found that the sensor used can see the ambient temperature and humidity and the bluetooth sensor control distance reaches 140 meters.

Abstract

Alat Penghemat Energi Vertikal which is the patent rights of Sriwijaya University  with identity number of IDP 000065109 is already developed in order to raised up the efficiency and the effectivity as energy saver and as heat and exhaust gas eliminator to prevent the users for health and comfortable matters. This product is now called Alat Penghemat Energi Vertikal Generasi Kedua (APEV-2). Among the improvements are the legs of APEV-2 is now made of steel, the base flat is also made of steel. The front air  window area is decreased and the  rack window binder and air hole at the bottom of the APEV-2.

Abstract

The use of accumulators so far as an energy source is only in an emergency situation and is limited by the time of use. The tool is called an Uninterruptible Power Supply (UPS). The way of  the tool works  is ineffective and unreliable, so there there needs to be a new innovation that can be used at any time and is not limited to the time of use. The results of the study present the coupling of two accumulators as a backup power source as an alternative provider of the main energy source that can provide a way out in the event of interference from PLN, and work for a relatively long time. Coupling of Two Accumulators as a backup power source begins with determining the characteristics of each component such as accumulators, inverters, rectifiers, current booster circuits, and voltage sensors. The next step is to determine the maximum loading for the system to work long enough. Furthermore, it is analyzed carefully and in a long time so that the design results is really suitable for use as a coupling of two accumulators as a reliable backup power source
