Makalah ini menyajikan sistem pakar untuk pemilihan unit gawat darurat rumah sakit di Kota Surakarta. Sistem ini dapat membantu tenaga medis saat menangani pasien gawat darurat untuk mengambil keputusan pemilihan rujukan ke rumah sakit yang tepat berdasarkan kondisi pasien dan ketersediaan sumber daya rumah sakit. Sistem ini berbasis website dan dapat diakses menggunakan telepon genggam. Sistem pakar ini dibangun atas model keputusan berbasis pengetahuan (knowledge base), basis data, dan antarmuka. Model keputusan berisi aturan (rule) dalam penentuan rumah sakit berdasarkan kondisi pasien dan data ketersediaan sumber daya rumah sakit serta data estimasi waktu tempuh tercepat sesuai peta digital Kota Surakarta yang diolah menggunakan sistem informasi geografis. Representasi pengetahuan disimpan menggunakan production rule dan mesin inferensi menggunakan metode runut maju (forward chaining). Hasil penelitian menunjukkan bahwa sistem pakar dapat bekerja dengan baik dalam membantu tenaga medis untuk memilih unit gawat darurat rumah sakit.

Penelitian ini mengembangkan modifikasi algoritma sequential insertion Suprayogi danImawati (2005) untuk dapat membentuk solusi layak bagi vehicle routing problem denganmultiple trips, time windows, dan simultaneous pickup-delivery (VRP-MTTWPD). Algoritmayang dikembangkan ini lebih luas kemampuannya karena juga dapat membentuk solusi modelVRPMTTW. Algoritma diuji pada sejumlah contoh data hipotetik dan diperoleh informasibahwa kualitas solusi dipengaruhi aturan yang digunakan untuk menentukan seed customer.

The research is aim to design the Key Performance Indicators (KPI) using Performance Prism Method with a case study of a batiks production house namely Batik Putra Bengawan. The research might assist the Batik house to translate the stakeholders’ satisfactions and contributions into organization objectives, strategies, business processes and capabilities. The level of achievement in each factor could be indicated through several performance indicators (PI). Then the importances of the stakeholders’ concern, organization objectives and the PI are measured using a concept that could accommodate a linkage among them namely the Analytical Hierarchy Process (AHP). By doing so, the KPI might be set based on the ten most importance PI such that the performance improvement could be done effectively. This PI design indicates the 25 PI spread over 12 objectives, 23 strategies, 19 business processes, 19 capabilities and includes six stakeholders. The importances wighted using AHP shows that the stakeholder employee has the highest importance and the community gets lowest importance level. The ten most importance PI are choosen as the KPI of the Batik Putra Bengawan. These are the employee productivity, the order fulfillment, the net profit margin, the absentism, number of loyal customers, the bonus receivers among employees, the ratio of new customers, the feedback periods, the consumers’ satisfaction index and the ratio of defect products.

Rancangan Informasi Eksekutif untuk Bidang Akademik dan Kemahasiswaan di Universitas Sebelas Maret Yusuf Priyandari; Yuniaristanto -; Utami Sri Sundari

Information system (IS) in Sebelas Maret University (UNS), especially for academic and student affairs is not integrated and it does not fully provide information for executives. Most of executive information or reports are provided in worksheet or paper-based reports. Ideally, the executive information should be served by an executive information system (EIS) that provide real-time information in order to support decision making for the executives. This study identify and design the executives information using the Wetherbe’s Approach with structured interviews based on Business System Planning (BSP). The stages in building the executives information are identification of user groups, identification of internal and external information which is needed by executives and management report, set information access matrix, arrange EIS conceptual framework, and initiate the EIS interface. The project result shows that there are 87 internal and 14 external information which needed by the executives. The executive information spreads in 52 internal and 8 external information in academic areas, and 35 internal and 6 external information in student affairs. The project also shows that only 15% and 17% of the internal information in academic and student affairs respectively which is supported by the existing information system in UNS. In the other hand, all of the external information can not be provided by the existing information systems in UNS.

This research utilizes the rearrangement on trip frequency of Batik Solo Trans as the solution for increasing their daily revenue. The first phase of the trip rearrangement is identifying peak hours of Batik Solo Trans and analyzing data distribution of passengers’ quantity. Next, Monte Carlo simulation is applied for evoking the passenger quantity data as the basis on trip frequency calculation. There are three types of trip frequency which are calculated, minimum, maximum and service frequency. The service frequency is a threshold between revenue and operational cost. At the last phase, sensitivity analysis is applied on service frequency calculation. This research shows that a suggested frequency (service frequency) could be applied when tariff for a passengers and passenger quantity are remaining unchanged. Besides, if Batik Solo Trans still use the old trip frequency, it’s suggested that Batik Solo Trans considers rising the tariff.
