Implementasi Pendekatan DMAIC untuk Perbaikan Proses Produksi Pipa PVC (Studi Kasus PT. Rusli Vinilon)
Get PDFThis study focused on quality improvement on PVC production process, which has high level of product defects of 6.04%. Six sigma with DMAIC (define, measure, analyze, improve, control) approach was used to improve the process. Each step of DMAIC was conducted to carefully analyze and keep the process precisely. The PVC production process contains a number of 6722.963 product defects in million opportunities (DPMO), with sigma level of 3.97. Three priority defects, based on pareto diagram tool i.e. scorched (35.12%), failed socket (28.22%), and standard of thickness (19.24%) will be focused on. In the improve step of DMAIC, FMEA form was used to propose some recommendations in order to improve the process, that are establish a mixing process standard time, training the operator whose responsible in each PVC process, establish an oven temperature standard in socketing process, and establish a standard set up of bolt adjustment to get the appropriate thickness of pipe
Model Penilaian Efektivitas Transfer Teknologi Pada Klaster Industri Mebel
Get PDFTolok ukur yang digunakan dalam menilai kinerjaindustri UKM adalah pencapaian nilai tambah, sehingga usaha untuk meningkatkan nilai tambah sepanjang rantai kegiatan merupakan salah satu strategi untuk meningkatkan keunggulan bersaing.Guna mendorong keberlanjutan bisnis UKM diperlukan adanya dukungan riset dan transfer teknologi, pemahaman manajemen dan kewirausahaaan, yang disertai dengan rangkaian sistem dan media kerjasama yang menjembatani keberadaan dan perkembangan riset, teknologi, manajemen, dan kewirausahaan terhadap pertumbuhan dan perkembangan perilaku dan kelembagaan UKM. Proses transfer teknologi seringkali mengalami kendala diantaranya kemampuan belajar/ pemahaman yang kurang terhadap adanya teknologi baru, rendahnya dukungan lingkungan, budaya masyarakat yang tidak mendukung, dan keengganan bekerjasama diantara para pihak yang terkait. Metode yang digunakan dalam penelitian ini adalah AHP. Output yang diharapkan adalah adanya model penilaian efektivitas transfer teknologi pada klaster industri
Evaluasi Heuristic Desain Antar Muka (Interface) Portal Mahasiswa (Studi Kasus Portal Mahasiswa Universitas X)
Get PDFThis study aimed to evaluate the interface design of student portal in University X using human factors and ergonomics interpretation approach, to increase usability and usefulness of the system. Heuristic evaluation by Molich and Nielsen was used as methodology. The result shows in general that interface design, ease of use (usability) of student portal in University X has been pretty good based on evaluation, but there are some things that need to be improved, especially in the characteristics of usabilit
Studi Meta Analisis Mengenai Absorbtive Capacity dan Inovasi
Get PDFThis study focuses on the correlation between absorptive capacity and inovation. Most theories believe that absorptive capacity is positively correlated to inovation. However, a survey on 34 studies with total sample size of 19,529 shows a wide variation of the correlation coefficients, i.e. from -0.080 to 0.640. This study applies a meta-analysis on those 34 studies to find the true correlation of absorptive capacity and inovation. A procedure of sampling error correction and measurement error correction was carried out, and the result shows that the true correlation is between 0.026 and 0.694 with mean of 0.36, which is significantly positive on 95% confidence interval. Further analysis finds an indication that other variable influences the strength of the correlation, leads to an opportunity to conduct further specific meta-analysis studies
Prediksi Kekuatan Otot Pada Kegiatan Lifting
Get PDFThere must be a lot of factors influence human muscle strength, both internal and external aspects. This study considers three main factors thought to affect human muscle strength, which are: muscle contraction, types of hand, and also gender. There are also covariance variables that are used, e.g. BMI and physical activity. Strength of biceps, forearms and trapezius muscles were measured using experimental design approach, among individuals with range of aged 19-24 years. Based on the calculation, all factors are proven to have significant correlation at significance level 0f 0.05. In addition, BMI and activity also has a relationship with muscle strength.Using all these factors, regression linear model was built to predict muscle strength. Additionally, maximum lifting strength was also estimated based on predicted muscle strength. Based on internal validity using paired t-test, the result show that predicted muscle strength and maximum lifting force have no difference to measured one
Kajian Exclusive Dealing dan Pengaruhnya terhadap Tingkat Persaingan Usaha dan Iklim Bisnis pada Rantai Pasok Industri Komponen
Get PDFSupply chain of vehicle industry is one of the supply chain that involves many entities. The high number of entities make the creation of a business network to improve the effectiveness and efficiency of business activities better known as vertical integration. However, the creation of excessive vertical integration and not pay attention to the rules of fair competition can also have a negative impact on the business climate conditions. Component industry as part of the car industry in the downstream sector has shown the existence of an indication of a exclusive dealing with their customers. The research conducted an analysis using structural equation modeling to know abaout the relationship between exclusive dealing indication the level of competition and the business climate in Indonesia component industry. And based on the processing and analysis of data, it can be concluded that there is a relationship between the indication of exclusive dealing with the level of competition and business climate of the industry

Estimation Quality Monitoring Glycerol Esterification Process with IR Sensors Using K Nearest Neighbours Classification
Get PDFThe commercial synthesis of fatty acid esters of glycerol is important because it can be used for other derivative production varieties. This research aims to construct the quality monitoring system for esterification condition faster and more efficient for the production of esterification glycerol. The monitoring systems were based on the measurement parameters from two inputs LED mid IR 3,4 and 5,5 μm sensors that using the data acquisition with computer database via USB 2.0 using Arduino Leonardo microcontroller and classifying the esterification quality condition using the classification method K-Nearest Neighborhood (KNN) The purpose of KNN method is to classify the variations of parameter inputs from the LED mid IR sensors in quality monitoring. In this research the condition of esterification was divided into three conditions: not good, fair,good., these classification was trained and tested in Orange Software for data mining using receiver operating characteristic (ROC) curve that is a graphical plot that illustrates the excellent performance of a classifier system for esterification condition with AUC . In application for quality monitoring, the influence of various parameters such as temperature set in the reactor has relation to the quality of product. By using this system, we obtained the optimum process conditions is 200oC and time needed for the process was 200 minutes

Estimasi Jarak Tempuh Order Picking System - Low Level to Part di PT. GMS
Get PDFTravel distance has an important role in order picking system, low-level picker-to-part, especially in warehousing productivity. Reducing travel distance means reducing travel time. Research was conducted at PT.GMS that uses random storage which means every item has an equal probability and every item is taken and used by production. Access frequency is assumed to be the same. Travel distance estimation is using probability calculation approach and combination with uniform distribution. Several methods are used to explore the shortest distance: Return Without Repetition, Midpoint Heuristics, and Traversal Without Skip. The results has shown that Midpoint strategy is better than Return Without Repetition and Traversal Without Skip
