Abstract

The marble industry in Tulungagung is one of the leading industries, besides the tourism and agriculture sectors. Ordering products in SMEs marble industry is divided into 2 types, first is when the supplier/retailer come directly into the industry and second is when SMEs marble industry received an order from a large company in Tulungagung. However, both orders are rare, even some SMEs marble never get an order for 1 month. Suppliers and retailers apparently also have difficulty in finding manufacturers to make products they want quickly. B2B e-commerce as a place to make buying and selling as well as marketing is perceived as the right tool to improve this condition. This research is made as an effort to solve the problem by giving priority to analysis and design of system design. The system is designed with the Code Igniter framework and used the Rational Unified Process (RUP) approach. This research is made by analyzing business process, use case, designing activity diagram, sequence diagram, class diagram, physical data model, and user interface. The result of this research is a better business process, which is 23 hours 40 minutes faster with order accepted condition, made 22 features, 22 use cases with activity diagram and sequence diagram with equal amount, and produce 4 controllers and 3 models on the class diagram. Evaluation results show that the flow on the system has been able to be understood by users, navigation and user interface design is easy to understand with an average is 86% in navigation aspect and 93% in interface aspect, and data on the research has been described in sequence.

Abstract

Materialized Query Table (MQT) stores data from frequently used queries so that users can get data without having to re-compute. This can improve system performance by reducing the cost of queries. The data in the MQT must be updated periodically it will not become obsolete when some change being made in the parent table. There are 2 (two) kinds of commonly used update mechanisms, namely full refresh and incremental refresh. Full refresh recompiles all data from the parent table. While incremental refresh only process data that being changed by utilizing staging table. The staging table stores the data changes (delta) in the parent table so that incremental refresh can be performed. This study simulates and compares the performance of full refresh with incremental refresh to know the impact of both of the query execution time and resource usage (I/O and CPU). The data used are original data derived from previous research and dummy data generated by system to support this research. Test results show that incremental refresh increases performance by more than 10 times at query execution time and increases more than 50 times on resource usage compared to full refresh.

Abstract

Printed Circuit Board (PCB) is one of the features available on the SFE-Electronics website. Recommended PCB ordering is expected to meet the needs of PCB buyers who can be ordered according to the needs of the buyer. However, in its application the PCB ordering feature has not been able to increase PCB bookings through the website. Of the total PCB sales only 6 out of 120 buyers make PCB order through the website. This study focuses on the evaluation and preparation of user interface design recommendations by adapting the Human-Centered Design (HCD) method. HCD is an approach method that incorporates a user's view of a system into the software development process to achieve a system that can be used as needed. Research begins with an initial evaluation conducted by identifying and analyzing stakeholders and understanding the user context and exploring the constraints of using PCB bookings. The second stage is to design the results of the first evaluation in which the results of the design is done further evaluation to find constraints on the design results. From the first evaluation stage found three obstacles on ordering PCB that is on aspect of user expectation, aspect of making of online form as ordering facility and participant response aspect. Nine pages of the design were made on the basis of the first evaluation results and from those nine outcomes were further evaluations that found obstacles on the PCB order page and automatic calculations which were then repeated.

Abstract

Consumer Price Index (CPI) is one of the most commonly used indicators in measuring the inflation rate. CPI's group of Transportation, Communication and Financial Services have the second largest proportion on living cost with 19.15%. As the group who categorize as administered price (the price are ruled by the government), forcasting this group would help some parties involved in taking neccessery decision and avoiding significant inflation rate. In this research, forecasting were performed using two Exponential Smoothing method which is, Holt's Exponential Smoothing and Winters Exponential Smoothing. This method was evaluated by calculating average error rate using Mean Absolute Percentage Error (MAPE) method. There will be 120 data from January 2017 until December 2017 that used which taken from Bank Indonesia official websites. The results of the test was the best parameter value for Holt's Exponential Smoothing which is 𝛼 = 0.7 dan β = 0.1 and for Winters Exponential Smoothing 𝛼 = 0.1, β = 0.4 dan γ = 0.8. And from this parameter's value, MAPE's value obtained for Holt's Exponential Smoothing which 0.474% and for Winters Exponential Smoothing is 1.503%. Both of them got MAPE value under 10% that can be categorize as very good on forcasting CPI group of Transportation, Communication and Financial Services. And can be conclude either that Holt's Exponential Smoothing have better accuration rather than Winters Exponential Smoothing in Cosumer Price Index's group of Transportation, Communication and Financial Services.

Abstract

Student Family Information System (KBMSI) is an organization formed from Student Information System Universitas Brawijaya. KBMSI also use the website as a medium to meet the information needs for the outside community as well as students of their own Information Systems, especially for Information System students themselves. With the website KBMSI expected society and student Information Systems get ease when looking for information about KBMSI. But it still needs to be considered by looking at the level of Usability on the website of the Student Family Information System (KBMSI). One technique to find out if the website is easy to use is by testing Usability. Usability is a quality that the product or service has about the level of convenience that the service user can do whatever it wants to do in the way it is expected to do. Based on interviews and observations made by the author, found some problems that exist in the website of the Student Family Information System (KBMSI). Based on the interview also found some empty website content. This will affect the user's expectation of the content. Website Family Student Information System (KBMSI). According to Michael O. Leavitt and Ben Shneiderman (2003) in his book Research-Based Web Design & Usability Guidelines, the website format must be ensured to meet user expectations, especially with regard to navigation, content and organization. the information presented in the website has not met the expectations of users.

Abstract

Cowshed is provided to shelter cows from the unfavorable weather and confine the cows' mobility in such a way that the fattening process gives rise to the accelerated increase of the bodyweight. Besides, cowshed of decent quality which is clean and comfortable can prevent cows from disease organisms to achieve the maximum rearing result. The problems confronted UPT-PT and HMT in Singosari in determining the decency of cowshed comprise the time efficiency and the difficulty in determining the criteria parameter used to assess the decency of the cowshed. The solution thereto is to capitalize on an intelligent system which, on the basis of the data supplied by UPT-PT and HMT in Singosari, provides a recommended measure of determining decency. The system is created in web-based using Analytical Hierarchy Process (AHP) method and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The AHP method was employed to gain the weight value of each criterion to be used in stage of weighting which yielded the preference value for each alternative in the TOPSIS method. The system output is an alternative data ranking based on its preference value. Testing was conducted by altering the pairwise comparison matrix in terms of the system prior to the matching between the system output and the actual data to get the level of system accuracy. The level of accuracy of the system obtained is 84.8%.

Abstract

The distribution is done to improving the productivity of the company. A strategy in the process of distribution is required primarily in determining the distribution route. An optimal route is essential in product distribution especially ice cubes. A company needs to send its products to multiple addresses, because the numbers of shipping addresses and varying distances creates a problem such as needing a long time to reach the destination. In solving these problem need a system that has a purpose to help the distribution process with the number of sales more than one, the problem is named Multiple Travelling Salesman Problem (M-TSP). One of the methods that can solve the problem of M-TSP is Artificial Bee Colony (ABC) algorithm which compared to other algorithm based on swarm intelligence. The initial process of ABC algorithm looks for random ice cubes distribution routes based on customer's ordering data. Furthermore swapping and insertion route is done then taken the route with optimal fitness. The last is comparison with the initial route whether the result is better or not. The test result show the numbers of optimal parameters are 23 size problems, 80 pop sizes, 10 limits, and 600 iterations. From these parameters obtained average fitness value based on system optimization of 0,078163 and manual selection of routes the sales goes through obtain average fitness value of 0,043472, with the result that path selection can be optimized by system.
