Abstract

Kidneys have a very large function for the body. The kidneys function as a filtering place for metabolic waste substances in the body so that if there is even a slight problem with the kidneys, the kidneys will not function properly, so that metabolic waste substances accumulate in the body and can become toxic in the body, causing various diseases. . There are many types of kidney disorders, in this study only 7 (seven) types of kidney disorders are discussed, namely N17 (Acute Renal Failure), N04 (Nephrotcyc Syndrome), C64 (malignant neoplasm), N39 (Disorder of Urinary System), N20 (calculus of kidney), and N18 (Chronic Kidney Disease). One way to find out kidney disease is to look at the symptoms. This study aims to determine kidney disease early on based on the symptoms experienced using the forward chaining method and then determine the level of certainty in the form of a percentage using the certainty factor method. The results of this study are patients with ID 125437 indicated to suffer from the type of disease with the largest percentage, namely malignant neoplasm with a percentage of 47%. The treatment methods are radiation therapy, chemotherapy, surgery, immunotherapy, cyroablation, arterialembolization and targeted therapy.

Abstract

The starter motor is a component in a vehicle that functions to start the engine for the first time by converting electric energy into rotary power. Where the motor starter system is used to rotate the crankshaft and then move the pistons so that the engine can start. Generally, cars use an electric motor combined with a magnetic switch to move the pinion gear that rotates to the ring gear and surrounds the flywheel and is bolted to the crankshaft. The starter motor must be able to produce a large moment from the small power available in a battery that has direct current. The purpose of this research is to find out how the mechanism of the starter motor works on the Toyota Kijang Innova 2.4 GA/T.  The research method used is a qualitative method, namely the method used to examine the components of the starter motor on the Toyota Kijangv Innova 2.4 GA/T. The results of this study indicate that the components on the starter motor of the Toyota Kijang Innova 2.4 GA/T  are all in standard condition.

Abstract

Transmission Off Highway Truck (OHT) 789C uses the Powershift transmission type. This type of transmission uses a hydraulically activated clutch. The main advantage of this powershift transmission is its very fast response when shifting gears without having to break the connection between the engine and the transmission. One component that plays a major role in this clutch is the plate and disc, which function as a medium for conducting rotation from the engine to the transmission, and this part also functions as the main frame of the clutch to withstand the workload. So that damage often occurs in these parts. This damage can occur due to several factors. An analysis is done to get the root cause and action to fix it. The purpose of the study was to identify the damage that occurred to the plate and disc and its causes. In this study, applying the 8-step method of applied failure analysis on a plate and disc transmission 789C which experienced normal wear and tear causing transmission slip. The results of the study using the 8-step applied failure analysis method showed that the root cause of the problem with the plate and disc transmission 789C was customer negligence in maintenance so that it accelerated wear and tear on the components, which caused the plate and disc to wear up normally so that contaminated oil caused the piston selector to be jammed. Reduced oil pressure results in a lack of lubrication and a transmission slip problem occurs.

Abstract

UPK Bukittinggi is a state electricity company in charge of 3 hydropower plants in West Sumatra with a vision to become the leading electricity company in Southeast Asia. To realize this vision, the company must continue to monitor a good level of productivity on the quality of engine performance which must be maintained. For this reason, it is necessary to propose a preventive maintenance plan for each hydropower plant with actions based on the Reliability Centered Maintenance (RCM) method. The purpose of the study was to calculate the amount of time for repair (Mean Time To Repair) and the amount of time the damage occurred (Mean Time To Failure) as well as determine the maintenance time interval schedule for the equipment experiencing the highest downtime at UPK Bukittinggi. Where the RCM method is integrated with the Failure Mode Effects Analysis (FMEA) method which is used as an analysis of the failure mode that occurs by calculating the highest Risk Priority Number (RPN) value on the machine and then calculating the time interval for damage as the basis for determining the maintenance schedule. The result of the research is that with routine scheduling of machine maintenance will be obtained with time intervals obtained by time intervals and maintenance actions using the RCM method.

Abstract

This conceptual article overviews the policy in implementing native-spearism-based English language proficiency tests at Politeknik Negeri Samarinda in connection to the ELT curriculum in which English is being a foreign language in Indonesia.  Representation of native-speakerism itself does not culturally and politically provide equality to all test candidates. Making a national standardized test would be a solution on the status quo.

Abstract

The starter motor is one of the most important components in the electrical system. This study was conducted to determine the damage to the electrical system of a heavy equipment unit.  The object under investigation is the starter motor on the planetary type Caterpillar 3306 engine. The method used in this study is library research which consists of collecting data from the Service Information System (SIS), Operation Maintenance Manual (OMM), and various modules related to the object of study. field observation by carrying out disassembly of the object is continued with a visual inspection and ends with measurements that will be compared with standard data. The results of this study show that the measurement results for speed are obtained 5169 rpm with standard specifications 7643 (out spec), on solenoid winding components for pull in resistance 0.5 ohms with standard specifications 0.43-0.49 ohms (out spec), hold in resistance 0.6 ohms with standard specifications 1.37-1.77 ohms (out spec), the field winding components 0.1 ohms with standard specifications 0.1 ohms (in spec),  x- and y-axis armature components are 51.9 mm each with a standard specificity of 52.0 mm (in spec), Commutator (in spec)
