A workload that exceeds the ability of workers or vice versa can cause a problem for workers. In this paper, we present a measurement of the physical and mental workload of workers at UKM Batik Jumputan Ibu Sejahtera Yogyakarta, and it has a purpose to find problems that occur so that recommendation for further improvement and problem-solving can be proposed. The physical workload measured by using RULA (Rapid Upper Limb Assessment) method, while the mental workload is measured by using NASA-TLX (NASA Task Load Index). This study succeeded in revealing the problems occur on workers such as there are differences in the level of worker risk which is caused by differences in age and differences in worker perceptions towards the dimensions of workload, and some workers experience high or very high levels of risk which is caused by improper work postures. Recommendations that can be done to solve the case are adding or replacing workers, increasing the workability of workers, adding work aids, changing work methods, and increasing workers’ understanding so that they can fill out questionnaires accurately.

Large organizations generally have assets distributed over separate locations. The problem is, decisions or policies will be easier to make if they are supported by a system that can dynamically visualize the existence of every asset owned by the organization. The WebGIS-based asset management approach is an alternative solution to this problem. This study examines a proposed WebGIS-based organizational asset management model. An application prototype was developed to test the proposed model using PHP, JavaScript, HTML, and CSS software. The Google Maps API is also used to create a base map. On the back end, authorized users can control and perform input, edit, and delete asset data. On the front end, public users can access public information. The test results of the developed prototype can provide various information on organizational assets visually based on digital maps that suit the needs of its users.

Map-based visualization of land ownership data is much needed by policymakers, both in government and private institutions. The utilization of this data is primarily to support macro planning, policy-making, and good governance. On the other hand, there are currently many application systems available which are the RDBMS database. This research examines the proposed RDBMS integration model and Google Maps maps to visualize land ownership data in a dynamic map view. The prototyping method is applied in this study to show how the available RDBMS can be improved to visualize land ownership data in a WebGIS-based application. The proposed model is tested using an application prototype. Technically the model can be implemented without significant constraints, but the actual implementation still faces obstacles, especially related to policies related to the cross-sectoral utilization of population databases and the obligation to maintain data confidentiality.

Schema matching plays a vital role in the information integration process from heterogeneous databases. Generally, the process of schema matching is to receive input, which are two databases (one as the source and another as a target), to match similarity attributes, and generate output in the form of mapping the similarity of the attribute pairs that are declared suitable. Furthermore, the user will assess these attribute pairs to determine whether the results obtained are correct or still need to be revised. Our previous study developed a model and software prototype of hybrid schema matching using a combination of constraint-based method and instance-based method. In this study, the model improved by adding new features. This paper discusses the increasing effectiveness of adding the features to customize the weight of matching criteria and string sizes matching. The hybrid model's best effectiveness is obtained when the weight of instance is 0.286, the type is 0.238, width i...

The weights have a very large influence on the parameter estimation of the geographically weighted regression (GWR). The weights show the relationship between observations or locations in the model. Types of weights that are often used in GWR are Gaussian kernels. This weighting can also be arranged into two forms. There are the fixed Gaussian kernel and the adaptive Gaussian kernel. Fixed is used when each location has the same bandwidth value. Adaptive is used when each location has a different bandwidth value. This study compares the results of the estimated parameters of the GWR model using the two weights. The modelling is carried out using data on maternal mortality in Central Sulawesi Province, consisting of 13 regencies/cities. The data used is secondary data. The result is that the adaptive Gaussian kernel weighting gives better results on the GWR model. It can be seen from the smaller standard error value (0.000398), the larger coefficient of determination (0.5468), and the smaller AIC (-152.52) than the model with the fixed Gaussian kernel weighting.

GIS concepts and applications evolved from a desktop-based into web-based and mobile. These changes require a new approach in the GIS database, from spatial data separation and attribute data into a database structure approach. The problem is the database for GIS is generally designed just for specific users, objects, and territory scopes, so it can’t be applied to other applications. This paper proposed a relational database model (RDBM) design that can accommodate new changes and needs in the user‘s aspect, the objects that are processed and displayed, and the scope of the region in GIS Web Applications (WebGIS). The study was conducted in 3 stages, namely a preliminary study to obtain an overview of the concept, design, and application of RDBM on various WebGIS. Next, identified potential problems in database design for WebGIS, and finally proposed an alternative solution in the form of a new database design template that could accommodate the possibility of new changes and needs...

Limited land for holding weddings at home is the reason for the development of wedding service providers. The problem that occurs in the selection of wedding venue services is that the bride and groom often have difficulty choosing a wedding venue that matches the desired criteria. Wedding management service providers also have difficulty recommending suitable wedding venues for brides-to-be and still being able to compete with other service providers. One solution to these problems is to provide a decision support system (DSS) for choosing a wedding venue by applying the SAW (Simple Additive Weighting) method. The DSS application that was developed was named MaVen, which stands for My Venue. The DSS application was developed using the SDLC method approach, the PHP programming language, and the MySQL DBMS. The functionality of the DSS application was tested using the black box method, while browser compatibility was tested using the Sortsite software. Based on the test results, ever...

The development of information technology led to increasing of requirement for communication networks.At the first, data exchange only using form of handwriting, documents, monthly reports, etc. But nowadays data exchange has grown into a network communication using the Internet for more quickly and efficiently. However, not all applications can pass the Internet, for security reasons or simply due to the limitations of the application itself. For applications that still require a local model or private network, the internet still can be used to make the process of tunneling protocol based on IP using EoIP feature, PPPoE, and PPTP in Mikrotik. This technique allows a local network or private network to communicate with the other local networks, through the public network (Internet). The issue of QoS becomes so important because the VPN is increasingly needed to connect a local network (private) with other local network through a public network (internet).

Schema matching is an important solution on the preliminary stage of information integration from the heterogeneous database. Basically, schema matching process is receiving a pair of a database as an input, matching a pair of an attribute, and verifying by the users to determine whether the result of pairing attribute mapping is already valid or need revision. The problem of schema matching is the difficulty on the mapping of pairing attribute manually, therefore, it is needed the semi-automatic and more effective model. The solution is by improving the computer-based model and combining the provided methods.
The hybrid model of schema matching combined the constraint-based method and instance-based method is developed in this research. The gained model is modified to increase the effectiveness of the result and the efficiency of the process. The model is arranged on the modules including, 1) input reading pair of the database as a DBSource and a DBTarget, 2) database, constraint, and instance extraction, 3) matching, calculation the similarity the pair of attribute (SIM), and the decision of the matched pair of the attribute, 4) user verification, and 5) model effectiveness test. The effectiveness of the model is measured using the parameter of precision (P), recall (R), dan f-measure (F). Model testing is conducted by applying relational database.
Based on our research it is found that a hybrid schema matching model combined the constraint-based method and instance-based method is more effective compared with the constraint-based method or instance-based method individually. The developed model can be applied to the process of schema matching on a relational database with DBMS and or with different application domain. The developed model can also be applied both in combination form and individually on their own method of the component.

The flexibility of database structure design is one of decisive factor of MIS quality. Based on logical database structure, this research aim to do flexibility analyzes; finding the general factors that cause inflexible; developing the flexible database framework for Academic Information Systems; and developing guidance to get the flexible database structure. This research conducted 28 databases that consist of 10 theses, 10 scripts, and 8 final tasks, that contain 262 tables and 1906 attributes. The flexibility analyzes done by using intuitive approach, furthermore flexibility level grouped into 5 levels by using Criterion Reference Evaluation (CRE) approach.
Base on research known, there are 3 database are VERY GOOD, it contain 49 tables and 443 attributes, consist of 371 (=83,75%) flexible attributes and 72 (=16,25%) inflexible attributes; 15 database are GOOD, it contain 119 tables and 664 attributes, consist of 464 (=69,88%) flexible attributes and 200 (=30,12%) inflexible attributes; 8 database are AVERAGE, it contain 78 tables
and 621 attributes, consist of 316 (=50,89%) flexible attributes and 305 (=49,11%) inflexible attributes; 1 database is BAD, it contain 10 tables and 137 attributes, consist of 49 (=35,77%) flexible attributes and 88 (=64,23%) inflexible attributes; there is neither VERY BAD; and 1 database can’t be analyzed. Base on designer educational, 9 database of MA degree that contain 126 tables and 1166 attributes are consist of 735 (=63,04%) flexible attributes and 431 (=39,996%) inflexible attributes, and 1 design can’t be analyzed; 10 database of BA degree that contain 65 tables and 383 attributes are consist of 38 (=62,75%) flexible attributes and 145 (=37,*6%) inflexible attributes; and 8 database of diploma degree that contain 65 tables and 316 attributes are consist of 222 (=70,25%) flexible attributes and 94 (=29,75%) inflexible attributes. In generally, database structure is not flexible caused by many factors that related to system boundary; data orientation; data standardization, data completeness, data group arrangement, code utilizing, primary key determining, and logic table utilizing. The framework of flexible database for Academic Information Systems can be design with involves any sub systems. The flexible database structure can obtain by 4 major stages, i.e. 1) Requirement analyzes; 2) Design; 3) Testing; and 4) Implementation.

PENDAHULUAN Kucing adalah salah satu hewan yang popular di kalangan masyarakat, bentuk fisik yang lucu dan tingkah yang menggemaskan merupakan salah satu alasan yang membuat banyak orang menyukai hewan peliharaan yang satu ini. Kepopulerannya membuat jumlah peminat kucing di Indonesia sangatlah besar, namun hal ini tidak diimbangi dengan pengetahuan pemeliharanya dan ketersediaan dokter hewan yang mencukupi. Di sisi lain, kemajuan teknologi komputer saat ini dapat dimanfaatkan untuk mengatasi masalah ketersediaan dokter hewan tersebut,yaitu dengan cara mengembangkan sistem pakar agar pemelihara kucing yang tidak mengetahui tentang penyakit pada kucing dapat mendeteksi sedini mungkin penyakit yang diderita pada kucing serta mengetahui cara penanganannya. Berdasarkan latar belakang tersebut,skripsi ini akan mengembangkan sistem pakar yang dirancang dari adaptasi kecerdasan bidang kedokteran hewan, yaitu untuk mendiagnosis penyakit pada kucing.
