METODE PREDIKSI BERBASIS GREY MODEL UNTUK PROGNOSIS PERAMBATAN RETAK
Get PDFThe crack is one of the frequent problems in engineering field. It effectively cause the component become fail. Therefore predicting crack growth is very important. Prediction was applied, so crack can be prognosed. In order to prevent failure in a component, crack prognostics have applied. The aim of this research is developing of Grey Model as a predictor, and application of developed Grey Model on crack growth prediction. The crack growth data acquired from experimental files were employed for evaluating the proposed method. A modification has made to improve the accuracy of prediction. In addition, error parameter has involved for evaluating the predicting performance.The methodology of this paper consists of five stages. That are theoretical study, simulation of basic grey model, background value modification, simulation of modified grey model, and application of modified grey model.The result shown there are decrease of error values on the prediction. The reduction of error values of three prediction data are 14,07 %, 4,01 %, and 6,93 % respectively. Thus, the development of grey model for crack growth prognostic has successfully made. Keyword: Crack, Prognostics, Grey Model, Prediction Metho
PENERAPAN METODE FMEA (FAILURE MODE AND EFFECT ANALYSIS) UNTUK KUANTIFIKASI DAN PENCEGAHAN RESIKO AKIBAT TERJADINYA LEAN WASTE
Get PDFABSTRACK Waste is an activity that absorbs or wasting of resources such as time or added expenses but do not add any value in activities. Each production process generally have opportunities for waste generation, especially on fast-food restaurants. To avoid or minimize the occurrence of such waste, waste analysis is needed. Waste analysis performed in this study using the application of FMEA method to determine waste criticality. From the result of the study, waste related to delivery process is becoming the most criticality waste with WPN at 99.16. Keywords: Waste, FMEA, WPN (Waste Priority Number), Fast Food Industry

The result of this study revealed three most critical waste concerning to the motion waste with RPN 84, overproduction with RPN 72, and unused people with RPN 60
Analisis Beban Pendinginan Produk Makanan Menggunakan Cold Box Mesin Pendingin LUCAS NULLE TYPE RCC2
Get PDFRefrigeration machines have become an important necessity in modern society’s lifestyle. To optimize the use of a refrigeration machine, the cooling capacity of the refrigeration machine must conform to the heat load to be tackled. This research was aimed at analysing the cooling loads of several food products, that are eggplants, cucumbers, tomatoes, and beer by using the cold box of Lucas Nulle Type RCC2 refrigeration machine in Mechanical Engineering Laboratory of Sam Ratulangi University. The required data in this research were the mass and temperature of the food products, and also the electrical current. The value of each data was obtained from three time experiments where each experiment was conducted in 60 minutes. Data analysis, then, resulted the cooling loads and required power of each food product, as follows: for eggplants, the cooling load is 62.91 kJ with power of 241.23 Watt; cucumbers, cooling load 41.55 kJ, power 243.10 Watt; tomatoes, cooling load 60,36 kJ, power 235,62 Watt; and beer, cooling load 18,21 kJ, power 231,88 Watt. key word: cooling load, Refrigeration machines , LUCAS NULLE TYPE RCC
PENGUKURAN KESENJANGAN KINERJA ANTARA SUPPLIER DENGAN CUSTOMER PADA RANTAI PASOKAN JASA PENDIDIKAN TINGGI MENGGUNAKAN METODE SERVQUAL
Get PDFPerformance is the key to measure the quality of service. On the other side an increase in the quality of service is one of the keys to winning the competition.The purpose of this study is measuring the service quality of services at the college using SERVQUAL. SERVQUAL method itself is a method to measure services through five dimensions namely Tangibels, Empathy, Reliability, Responsiveness and Assurance.The results of using SERVQUAL method from 25 variables obtained dimensions that has the biggest gap is Tangibels, Empathy, and Responsiveness. Keywords: Performance, SERVQUAL, Quality Ga
PENERAPAN METODE ANOVA UNTUK ANALISIS SIFAT MEKANIK KOMPOSIT SERABUT KELAPA
Get PDFAnova test is a form of statistical hypothesis testing where we draw conclusions based on data or inferential statistical groups. The null hypothesis of the Anova test is that the data is a simple random of the same population so that it has same mean and variance expectation.              The aim of research is to obtain the optimum bending strength of coco fiber composite for volume fraction of 0 % fiber and 100% resin, 10% fiber and 90% resin, 20% fiber and 80%resin, 30% fiber and 70% resin, 40% fiber and 60% resin, 50% fiber and 50% resin, 60% fiber and 40% resin, 70% fiber and 30% resin with alkali treatment for two hours and without treatment, and find the result of fracture at the specimens.              Based on anova analysis with error percentase 0,05 obtained F count> F crit so that answer hypothesis to fiber treatment affect mechanical properties of bending strength F = 7.752752499 F crit = 2.657197 without treatment. Keywords : Anova Test Methods, Analysis Of Composite Mechanical Properties, CoconutFibers

RANCANG BANGUN PENGGERAK ALAT JEMUR PAKAIAN OTOMATIS BERBASIS ARDUINO UNO ATMEGA328
Get PDFRain or bad weather until recently a major problem for people who have a clothesline. Typically the clothes are dried often left to travel, so do not have time to pick up a clothesline at the time of going to rain atupun was night. to address the problems raised clothesline when it rains and it was night then the need for automated control systems by making automatic clothes line actuator. By designing all the tools from the sensor light dependent resistor (LDR) as a detector of sunlight, water sensor as a detector of rain, the DC motor as a driver, and Arduino Uno as the brain of the maker of the command of the tool, it can be made a clothesline automatically to help work in lifting clothes when it rains.           From the test results the tool that has been designed. The tool works every time the sensor will read the weather around, such as when the sensor does not detect the light that the circumstances surrounding the Arduino will translate as cloudiness / dark, so that the DC motor will draw a clothesline into the house. When the sensor detects sunlight LDR then Arduino will translate around the hot weather, it will come out ortomatis clothesline. Meanwhile, when the water sensor detects raindrops then be translated by Arduino as rainy weather and then the DC motor will draw a clothesline into. From these test results mover based automatic clothes drying apparatus arduino Uno ATmega328 has worked as expected and a solution lifter or a clothesline when rain was night. Keywords: Automatic clothesline, LDR Sensor, Water Sensor, Motor D
