Abstract

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.

Abstract

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.

Abstract

Ada 292 sekolah dasar yang terdapat di Surakarta baik sekolah dasar negeri maupun sekolah dasar swasta. Sekolah tersebut tidak hanya didominasi oleh siswa yang berasal dari kota Surakarta saja, namun juga terdapat siswa dari luar kota Surakarta. Kondisi itulah yang memunculkan adanya bisnis layanan antar jemput bagi siswa. Salah satu faktor yang menjadi pertimbangan dalam bisnis kendaraan antar jemput adalah biaya. Beberapa pihak pengelola mengalami kesulitan dalam menentukan besarnya biaya layanan antar jemput dikarenakan penentuan biaya yang sudah ada hanya menggunakan jarak terdekat dan terjauh. Oleh karena itu, untuk mengetahui kelayakan bisnis dan besarnya potensi layanan antar jemput perlu diadakan evaluasi. Evaluasi pada penelitian ini menggunakan studi kelayakan bisnis yaitu dengan menggunakan payback period, net present value dan IRR. Tahap awal evaluasi potensi bisnis ini adalah mengidentifikasi jumlah siswa yang menggunakan layanan antar jemput dan biaya layanan antar jemput. Tahap kedua adalah memetakan sebaran siswa layanan antar jemput dengan menggunakan GIS untuk mengetahui estimasi jarak tempuh. Kemudian, menghitung biaya per km sebagai dasar perhitungan kelayakan bisnis layanan antar jemput. Tahap terakhir adalah mengevaluasi kelayakan bisnis. Hasil evaluasi kelayakan bisnis layanan antar jemput berdasarkan studi kelayakan investasi diperoleh hasil untuk payback period sebesar 3 tahun 8 bulan lebih rendah dibandingkan ketentuan umur ekonomis 8 tahun. Net Present Value sebesar Rp 71.155.644 lebih dari 0. Nilai IRR sebesar 41% lebih tinggi dibandingkan suku bunga bank 12,38%
