Abstract

In fulfilling economic needs in Indonesia the agricultural commodity sector has a very important role. Due to agricultural commodities are the livelihoods and basic consumption of the people in Indonesia. Daily people's needs cannot be separated from agricultural commodities, one of which is large red chili. This is due to the level of consumption of large red chili used for kitchen spices and the ingredients are quite high. Therefore large red chili which is included in agricultural commodities can be categorized as the primary food needs in people's lives. The prices of large red chili which are erratic and tend to rise can cause losses to the state and society. To overcome this problem, one solution is to forecast prices that can be used to predict the possibility of chili price increases quickly and accurately. This study aims to forecast the price of large red chili using the ELM method. Based on the results of the implementation and analysis that has been carried out using the data of large red chili prices from July 18, 2016 to December 28, 2018 the smallest error was obtained using Mean Absolute Error (MAPE) of 3 % using 2 feature, the number of neurons as many as 3 and the range of weight values ​​[-1,8, 1,8].

Abstract

Brawijaya University Faculty of Computer Science had many students. The Information system study program from the generation 2011 to 2018 has 1817 college students, but the number of students who graduate and enter is disproportionate, so that students who do not graduate on time can reduce accreditation from major, faculty or university. Based on that, the amount of data available can be used as an algorithm in data mining to predict students graduates. The C4.5 algorithms are one of the algorithms that can be used in predicting students graduation by producing a rule in the form of a decision tree. The data used in this study is student academic data from semester 1 - 4. Using the algorithm C4.5 generated accuracy by 90.9%, while ROC's curve of AUC values is 0.8232. the usability value produced from SUS is 67.5. The output generated by a dashboard display with some graphic that contains the graduation percentage, the graduation recapitulation of each generation and the value details of students, is also a form for data input that can be used by the head of program information system study program to predict by uploading collective data or linear data.

Abstract

One of universities in Palembang city, Sriwijaya University, where the university has used a web-based information system to support the student's academic process. The application was realized in web media which was later better known as Unsri's academic. But sometimes the quality of service of a college website has not been able to meet the expectations of it's users, so in order to maintain or even improve the quality of services, a website must certainly get special attention. So the quality of universities in terms of website assessment is better. So from that quality improvement in website-based services is an effort that must be carried out continuously. This study was conducted to determine the value of service quality of the academic site Unsri from the user's preception using Webqual 4.0, find out the effect of usability variabels, information Quality, Service Interaction Quality and find out the Importance Performance Analysis (IPA) quadrant grouping on each webqual indicator. This research uses data collection techniques using questionnaires with a total sample of 117 respondents. The results of the IPA quadrant analysis indicate that there are five attributes that are the top priority in improvement, namely, attractive appearance, additional knowledge from website information, providing up to date information, providing sufficiently detailed information, and users feeling safe about their personal information. Furthermore, there are five attributes that are included in the low priority of improvement , namely ease of navigation, proper preparation of information, user feel safe to make transactions, website provide space for personalization, and websites make it easy to communicate with organizations. Other attributes do not have priority improvement because they are classified as quadrants that have sufficient service performance values to be maintained or even have excessive value.

Abstract

Two types of cost estimates are algorithmic and non algorithmic. PT Piramida Teknologi Informasi uses non algorithmic estimate because it estimates based on previous project data and guesstimate. PT Piramida Teknologi Informasi often suffers project delay in processing time in a risk of loss in term of costs. PT Piramida Teknologi Informasi defined the cause of their project problem is the lack of human resource. This study used Revised Use Case Point (RE-UCP) to resolve them. Algorithmic estimate was selected because this type can produce estimate accurately. Re-UCP is algorithmic estimate.Re-UCP was selected because it has more implemented advantages in various project range and close to actual effort value (precision). Re-UCP value was converted into effort in staff hours. Effort becomes the basis of making time and cost allocation. This study did not count the number of human resource but made an allocation for each project activities. SIPAP and SIM JALAN were used as test data in this study. The result showed that SIPAP can be completed at a cost of Rp 184.769.238,37 for 686,7 hours by 7 people. While the SIM JALAN can be completed at a cost of Rp 210.302.26,09 for 568 hours by 8 people. Re-UCP also shows several important things such the development risks that affect cost and time since early phase, possible solutions taken (i.e determined overtime for SIM JALAN), and company's opportunities. The result of this study can be used by project leader or manajer project in making decision such as making scheduling dan knowing benefits of project based on software size.

Abstract

The number of movie production have increased each year. This shows that the society interest in the film industry is getting higher. It's difficult to get the appropriate result of what desired by searching for data with certain parameters on the internet because of the large amount of data exists but there is limited adequate tools. The screening of the excess data can be done using recommendation process. There are several stages in movie recommendation process. Those are Pre-processing to process film synopsis documents, TF-IDF method to obtain the highest value as much as the amount determined based on the query result on the document. Word2vec as a method to get the query expansion from the top word result that taken from TF-IDF process and Cosine Similarity is used to get the similarity between document and query. The Word2Vec method plays role to find the proximity value between words to one another in order to get the words that will be added to the initial query. The training data are 150 movies title with English synopsis. The evaluation process took 30 data of movie title and synopsis from the training data based on the movies selected by the examiners. The highest Precision@k value is 0,47 and the highest Mean Average Precision (MAP) value is 0.709603374.
