ANALISIS DAN PERANCANGAN SISTEM INFORMASI MANAJEMEN DI KLINIK PRATAMA BSMI KLATEN

Clinic is a health service facility that organizes individual health services that provide basic and specialized medical services, is organized by more than one type of health worker and is led by a medical staff (Menkes RI, 2001). Clinic Pratama BSMI Klaten is an institution engaged in the field of health services that provides quality basic health services. Present as a follow-up to the post-earthquake service process in Yogayakarta-Central Java on May 26, 2006 Inaugurated on November 13, 2006 by the Chairperson of the MPR. RI Dr. Hidayat Nurwahid, MA and the general chairman of BSMI DR.dr. H. Basuki Supartono, SP.OT, FICS, MARS. So far, the recording of patient medical records at the BSMI Klaten Primary Clinic is still using book media. This means that all these activities are carried out without the assistance of a computer so that it can result in lost or lost clinical records of various data. This, according to the author, is still very ineffective because it makes it difficult when presenting data such as an example of presenting data on treatment history or medical records for each patient which will take a long time. To overcome this problem, an information system that is able to provide fast information to patients and the public is needed. In order to improve services and improve the performance of each unit which is interconnected and integrated. Analysis and design of management information systems at the BSmi Klaten Pratama clinic which was made using the PHP programming language and the server using MySQL. The designed process consists of a registration unit, an initial examination of the patient by a nurse, a doctor's examination, a medical support unit, a pharmacy and a cash payment system, each of which can be data-integrated in a Clinical Management information system

The Proposed Dashboard Model for Measuring Performance of Small-Medium Enterprises (SME)

The era of free market and the more dynamic environment condition forces many companies to establish the proper strategy. Implementation of a correct strategy can increase the effectiveness and efficiency of the use of the company resources. The system of measuring performance is one of models used to monitor the success of implementing objective strategy which has been determined by the leader of the company, including SME (small- medium enterprise). However, a lot of SME do not have clear vision and strategy. It is because the SME orientation only focuses on more dominant operational performance. Therefore, smart system can be used to arrange a parameter of performance measurement. AHP (Analytic Hierarchy Process) is used to determine the priority from each criterion from KPI (Key Performance Indicator). Knowing the proper need, the company can determine the priority to select if the company has limited fund and resources. Moreover, the assessment system used in this research uses OMAX (Objective Matrix) method for each KPI. To assess, the measurement uses the concept of traffic light system using 3 colors: green (achieving a target), yellow (close with the target), and red (far from target). Nevertheless, this KPI needs to get attention in the next period. The research observes 3 SMEs located in Krebet tourism village. They are SME Ragil Handicraft, SME Sanggar Punokawan and SME Yuan art. The result shows that there are 31 keys performance indicators (KPI) used to measure the performance of SME. The assessment result of OMAX shows that there are still a lot of KPIs with red color. Thus, they need to be repaired. Knowing the performance of SME still far from target (red), the sources of the problem can be identified, so that the reparation target done by SME is more appropriate

Managing maintenance resources for efficient asset utilization

Asset productivity is concerned with how an asset is efficiently and effectively deployed and utilized. It is related to maintenance resource management. The purpose of this paper is to discuss development of policies for managing integrated maintenance resources. These resources include human resource and supporting material required to perform maintenance activities for a complex maintenance system. Here, human resource management encompasses policy for recruitment, training, and outsourcing. Meanwhile, supporting material management includes policy for parts purchasing and inventory. Good asset productivity can be achieved by attaining a better performance of the asset using the same amount of maintenance resources or by reducing the amount of maintenance resources used for the same asset performance. A maintenance department may manage each kind of resources and have its own policy to achieve better asset productivity. In this way, an integrated policy with all related departments is required. In this research, a model to determine an integrated optimum policy with associated departments is developed. It consists of three sub models representing three different departments in an organisation including Maintenance, Human Resource, and Inventory and Purchasing department. Through the model, some combinations of the policies can be made and tested to find the best combined policy that, in turn, can help to generate better asset productivity

Data-Based Maintenance Strategy Analysis using Operational Excellence Approach in Engineering Asset Management

Traditionally, selecting maintenance strategy is based on reliability or cost. In this paper, a further discussion of redesigning the maintenance strategy is presented. The process of redesigning the maintenance strategy applies reliability centered maintenance approach and the result is analyzed further with the approach of operational excellence as presented in the structure of operational excellence. The output from the reliability centered analysis is three recommendations related to maintenance strategy. Then, the recommendations are aligned with the structure of operational excellence. The main conclusion of this study is the operational excellence approach is capable to assist the process to redesign the maintenance strategy by providing the decision maker with a guidance to improve productivity

A modelling approach for maintenance resource-provisioning policies

A study has been undertaken to understand the capability of system dynamics modelling in simulating interrelationships between maintenance and the resource provisioning policy. A review of the literature indicates that such an approach to resource provisioning policy selection considering the characteristics of maintenance and considering life cycle cost is both absent and would be of benefit. The development of a system dynamics approach integrated with life cycle costing algorithms has been pursued. The results have been tested on 3 case studies to determine the suitability and accuracy of a new combined system dynamics simulation and the life cycle cost model

NOVELTY DOES MATTER: SLM IS A CONVENIENT WAY FINDING A RESEARCH ORIGINALITY

A good research is a research with a clear research novelty of research originality. However, finding the novelty or originality is one of the most challenging process in research in any field.  Although there are many proposed models to assist researchers and scholars to determine research novelty-such as Systematic Literature Review, K-Chart, Card System, Decision Tree, Mind Mapping- most of the tools or models fail to fulfill the need of some researcher to effectively present the complex result of literature review. To deal with this obstacle, a new tool named SLM (Systematic Literature Mapping) is proposed in this article in order to visually present the result of a complex literature review in the form of a decision tree that leads to an effective and efficient literature review process. The newly proposed model combines SLR (Systematic Literature Review), an established-well-known tool for literature review with a model named K-Chart. To verify the proposed model, a case study is discussed to accompany the example of the application of this new tool. The case study is finding the research opportunity of the application of big data in the industry.  The result shows that SLM is capable to serve its purpose in the process of literature revie
