Abstract

A tracer study is an approach that allows higher education institutions to obtain information about possible deficiencies during educational process and learning process and activity planning for improvement. Institute of Student Affairs never do a tracer study data analysis, although tracking of graduate student has been periodically using web-based application but the previous data is still in old format. Tracer study process is only once time in order to completed   accreditation requirement for department. In this research we will focus in developing the application using FOLDARM method for student tracer study. Application is created using the CI Framework programming language with   Mysql as backend database. The test is done using lift ratio method. The result show, association of the patterns are counted by 3, 24% support and confident 45% and it that meet the criteria. By using lift ratio test, the pattern that has the strongest relationship is if the waiting period in finding a job is 3- 5,9 month and first salary is below Rp. 1,572,200,-  and IPK is between 2.75 - 3.50 and graduation age is between 15-24 years old.

Abstract

The Central Bureau of Statistics of Indonesia (BPS) classified the target households into three different categories which were very poor households (RSTM), poor households (RTM), and nearly-poor households (RTSM). BPS need some method that can accelerate the classification process to assist the performance of BPS in order to shorten the processing time. The data scale that used in the classification of poor households was ordinal. Generally, calculations of classification using ordinal asscales only can be found in the software WEKA Ordinal Class Classifier (OCC) that was one of the existing classification in WEKA. OCC could be resolve to attributes that are nominal, numerical, and ordinal. So in this research, OCC would be using to classify poor households. By comparing the algorithms performance there were several stages that need to be traversed. The first was the data collection stage, the second was the data processing stage and information by using preprocessing, the third was the analysis stage with tools WEKA. The fourth was a test stage by counting the value of accuracy, precision, and recall. The last stage was evaluation by comparing actual data with predictive data of the result of calculating system. From the classification process, it can be concluded that OCC has the highest accuracy, precision, and recall level which is 90% (3803) of training set and 10% (423) of testing set with accuracy of 90.5437%, precision 0.919, and recall 0.905.

Abstract

A group-based sharia savings and loan cooperative is different with the common cooperatives out there. This unique cooperative’s process business made its staff not being able to use a usual cooperative information system without being customized. A SWOT analysis has been conducted to decide whether this kind of cooperative need to develop a new information system or not. The results showed that a new information system is definitely needed. An information system of sharia-based savings and loan cooperative with special features to handle group transactions of cooperative members has been designed and developed, although it’s not yet perfect, to help ease the staffs’ workloads. User centered design approach was used to develop this information system since the users are the ones who know best what they need and do. Several diagrams were created to design the system, such as: use case diagram, architecture system diagram, data flow diagram, entity relationship diagram, and the user interface mockup. This information system has several main modules, such as: Member Service, Transaction, Authorization, Back-Office, Reports, and System Configuration. Blackbox tests have been done to test whether the system is functioning properly or not.

Abstract

Decision support systems, commonly called DSS (or SPK in Bahasa), in medical used to diagnose illness. But within its implementation these systems are not used optimally. The main cause is the interface of the systems that is not accordance with the user wants. Three interface designs layouts were proposed for the phase of history and physical examination and two interface designs layouts for investigations to be assessed by the respondents. Based on the results of the questionnaires selected by respondents, statistical tests were performed to determine the value of the use of interface design based on the Technology Acceptance Model (TAM) and modified TAM. The statistical methods used to examine the effect of variables on TAM and modified TAM i.e. the Structural Equation Modeling Partial Least Square (SEM PLS) method. The results of this study indicate that the respondents’ choice in the TAM and modified TAM model for the history and physical examination is the same as the based filling system. While for the supporting stage there are differences of respondent choice on TAM model with choice of graphical interaction system and on modified TAM model with windowing system option.

Abstract

Optimization of a prediction (forecasting) is very important to do so that the predicted results obtained to be better and quality. In this study, the authors optimize previous research that has been done by the author using backpropagation algorithm. The optimization process will use Conjugate Gradient Beale-Powell Restarts. Data to be predicted is Consumer Price Index data based on health group from Medan Central Bureau of Statistics from 2014 until 2016. Previous research using 8 architectural models, namely: 12-5-1, 12-26-1, 12-29 -1, 12-35-1, 12-40-1, 12-60-1, 12-70-1 and 12-75-1 with best architectural models 12-70-1 with an accuracy of 92%. In contrast to previous research concentrating on finding accuracy using backpropagation, this study will optimize the backpropagation with Conjugate Gradient Beale-Powell Restart, which not only focuses on accuracy but also the convergence of the two algorithms and the translation of predicted results, which is not done in a previous study. This research will use the same architectural model as the previous research and will get the result with the accuracy of 92% with the best architectural model that is 12-70-1 (same as previous research). Thus, this model is good enough for prediction even with different algorithms, since the accuracy of converging backpropagation with Conjugate Gradient Beale-Powell Restarts.

Abstract

Energy and mining reporting have to conduct for the exploration company in order to make control while exploration. Government control can perform by making profiling of energy and mining data that exist in the area as consideration in taking policy or decision. Stages of energy and mining reporting are very important to do especially in areas that have energy and mining resources such as Musi Banyuasin regency. Profiling can performed by mapping the location of energy and mining results using a geographic information system (GIS) to organize data between explorers and governments. Based on these conditions GIS was developed using a technique that prioritizes user needs with extreme programming development techniques. The result of GIS development shows that the processing of data becomes information based on spatial and non-spatial data with the final result of energy and mining report. The report presented can be used as a report to the relevant parties as an effort to open data of energy and mining as material in decision-making or policy. Geographic information system generated systematically developed using extreme programming approach with five stages of exploration, planning, iteration, production and maintenance so that it can run funtionaly according to its function
