Abstract

Point of Sale (POS) application in MSMEs is used as a tool for making sales. La Fresa Farm uses POS Intuit QuickBooks Enterprise 2015 application. As long as this application is implemented, users need a fairly long interaction time. Seeing these problems, tools are needed to evaluate the use of the application. In this study, the evaluation model used is the Technology Acceptance Model (TAM). TAM describes the ease of use and usefulness variables as the first measuring variables that affect other variables to the actual to use variable. The ease of use variable is the interaction time, which is measured using Keystroke Level Model (KLM). The usefulness variable is measured by cognitive models. In this study, there are additional variables outside the TAM model, namely self-efficacy, timeliness, and complexity. The test was carried out by the POS Intuit QuickBooks Enterprise 2015, Moka, Pawon, and Olsera applications. The KLM test results showed that the fastest time was 89.8 seconds and the results of TAM evaluation on Moka showed that the results of the actual to use variable response had a positive response, so that the interest of users using Moka was quite high.

Immunization has become mandatory in Indonesia, especially for children under the age of 12 years. Currently there are health centers that do not have a historical immunization record of each baby so the records of immunizing all babies are merged into one book. Currently the processing of delivers information held by health care facilities is still using the immunization schedule card provided during registration immunization program. Accordingly communication between health care facilities with parents of babies is not efficient. Therefore the aim of this research is to produce the design of immunization information system that helps the health care facilities to provide information and data about immunization schedule each of baby. On systems that have been designed, the health center can obtain data and information of the babies that follows immunization program quickly, providing an accurate historical data record of immunization and information about immunization schedule would do next. By using SMS Gateway technology that could remind and warned parents about schedules and types of immunization to be received next through these technologies.

Abstract

Management of Type 2 Diabetes Mellitus requires multidisciplinary treatment that includes non-drug therapy and drug therapy. Drug related problems, the state of occurrence of a discrepancy in the achievement of the goal of therapy as a result of using drug. Therefore, drug therapy can use traditional medicine as alternative solutions because it has minimal side effects. But seen from the development of information circulating regarding traditional medicine DM-reviewed yet complete. And if the information required aspects are met then it will have a positive impact benefits in terms of medical, especially in the dissemination of information. In the midst of the development of information technology today, the role of the application can help to contribute to improve the situation is the case today. Problems that occur at this time are with the limited media collaborative applications that are in the process of delivering, distribution, and storage of existing knowledge, resulting in knowledge sharing process is inhibited. To solve these problems, this research designed a Knowledge Management System (KMS). KMS was developed with web-based technology Web.2.0. With KMS design, then the process of sharing knowledge is not only shared by every user but is collaborative with the doctor to ensure the dissemination of knowledge
