Abstract

Latar Belakang: Salah satu keluhan pasien yang paling sering muncul adalah lama waktu yang dihabiskan pasien di unit gawat darurat setelah mereka mendapatkan penanganan pertama. Pasien harus menunggu sebelum mereka bisa pulang, atau dipindahkan ke bangsal perawatan, ke ICU atau menjalani operasi. RSPAU Dr Suhardi Hardjolukito adalah RS tipe B dengan kapasitas 215 tempat tidur. Tujuan: untuk mengukur lama waktu yang dihabiskan pasien di UGD dan menganalisis faktor-faktor yang mempengaruhi lama waktu tunggu tersebut. Metode: Ini adalah penelitian observasional dengan rancangan cross-sectional. Penelitian dilakukan di unit gawat darurat RSPAU Dr Suhardi Hardjolukito, yang memiliki kapasitas 15 tempat tidur, pada bulan November 2014. Observasi dilakukan selama 7 hari pada shift pagi, sore, dan malam. Sejumlah 305 pasien menjadi sampel penelitian dan diamati selama pasien berada di UGD. Hasil: Rata-rata waktu perawatan di UGD RSPAU dr.S.Hardjolukito masih sangat bervariasi, berkisar antara 8 s/d 270 menit (4.5 jam). Tahapan pelayanan yang memiliki waktu tunggu paling lama adalah pelayanan di laboratorium dan radiologi. Sementara karakteristik kunjungan yang paling besar pengaruhnya terhadap lama pelayanan di UGD adalah kunjungan pada hari kerja, jenis kelamin pasien perempuan, diagnosis emergency, dan waktu kunjungan pagi hari.  Kesimpulan dan Rekomendasi: Waktu yang dihabiskan pasien di UGD RSPAU dr.S.Hardjolukito sangat bervariasi. Banyak penyebab waktu tunggu tersebut sebenarnya tidak penting dan bisa dicegah. Rumah sakit harus mengurangi kepadatan UGD pada waktu-waktu sibuk dengan meningkatkan efisiensi RS, memperbaiki alur pasien, dan menggunakan metode maajemen operasional dan teknologi informasi

Abstract

Level of the product availability becomes a problem at the company, because of the fluctuation and the uncertainty of demand from the consumer and happened when the company determined the cycle service level which is the indica- tor of supply chain performance in fulfilling the availability of the product and avoiding either stock out or over stock in replenishment cycle. This research was conducted at UD As-Salam. The aim was to improve supply chain perfor- mance through determining the optimal cycle service level of product availability. Therefore, it was needed to set up the optimal level of product availability to optimize the profit. There were some steps that were taken in this research: determining the optimal cycle service level, optimal order size, expected profit, and sensitivity analysis between optimal cycle service level and expected profit. The result showed that the cost of under stocking and over stocking were 4,144 rupiahs and 6,573 rupiahs, respectively. The optimal cycle service level was 63 % with optimal order size was 2,842 kgs/month. This value improves the company’s profit in the amount of 11,043,570 rupiahs. The improvement of supply chain performance based on product availability analysis could increase profit up to 127,891 rupiahs.ABSTRAKLevel ketersediaan produk menjadi permasalahan pada objek penelitian ini karena adanya fluktuasi dan ketidak- pastian permintaan dari konsumen yang timbul ketika pelaku usaha telah menentukan cycle service level.

Abstract

Crude-Palm-Oil (CPO) is an agro-industrial commodity which has a strategic value to be developed for Indonesian economy and social welfare. Production and export of Indonesian CPO increase progressively in the view years so that CPO is one of the pre-eminent products of Indonesia. On the other hand, however, they could give two negative impacts. First, a less CPO supply for domestic market as a result of export growing. Second, a worse environment as an effect of the opening new palm plantations. We, therefore, construct and simulate the system model for analyzing the relationships between the components and for describing their behaviour within the supply chain of CPO by using a dynamic model. The result shows that in the next 30 years, the revenue of Indonesian CPO industries tends to increase. The biggest revenue will be achieved in the year 23rd. The maximum addition of plantation employees is in the year 7th as well as in the year 17th. Deforestation would be the highest in the year 7th and 17th in which 2008 as a basic year.

Abstract

This paper deals with supply chain management within bakery industry from the perspectuve of material management. A better material requirement planning was proposed. The result showed that the proposed MRP can decrease cumulative material investment that the existing operation. By considering the impact of product-retur precentage scenarios (75%, 50%, 25%, 0%) to comapny's hplding cost, it was known that the decreasing of product-retur percentage is not significantly reduce the retrenchment of cost paid by the company. A low percentage level of product-retur might sacrify customer service because the retailer can not assure the product availability. On the other hand, a high percentage lebel ,ay give high level of customer service, however the cost is more expensive resulting in the reducing of the profit. This, represents a trade-off between profit to be obtained by the company and customer service level.ABSTRAKTulisan ini membahas tentang pengelolaan supply chain di dalam industri bakery dari perspektif manajemen material. Sebuah perencanaan kebutuhan material (MRP) yang lebih baik kami usulkan. Hasil penelitian menunjukkan bahwa usulan MRP dapat menurunkan jumlah investasi material daripada yang ada sekarang. Dengan mempertimbangkan pengaruh skenario persentase product-retur (75%, 50%, 25%, 0%) terhadap biaya persediaan perusahaan, diketahui bahwa penurunan persentase product-retur tidak begitu berpengaruh pada penghematan biaya yang menjadi beban perusahaan. Pada suatu tingkatan product-retur yang rendah akan bisa berakibat pada turunnya customer service karena retailer tidak bisa menjamin ketersediaan produk. Pada sisi lain, product-retur dalam jumlah banyak akan memberikan customer service lebih baik namun dengan biaya yang mahal sehingga akan ada pengurangan keuntungan. Hal ini menunjukkan adanya suatu trade-off antara keuntungan yang diperoleh oleh perusahaan dengan customer service level di dalam suatu supply chain. Oleh karena itu kita perlu mengoptimalkan keseimbangan antara keuntungan dan customer service level.

Abstract

This research aims to predict and describe the sustainability of Indonesian furniture development by considering 3 as- pects: economical revenue, social, and envieronment, as the main aspects in a sustainable supply chain. This research was started by identifying the basic model of supply chain of furniture industry. We, then, identified the potency and weaknesses from either internal or external, by using SWOT (strength, weakness, opportunity, threat) analysis. We used modeling and simulation to describe the system behaviour. The result showed the characteristics of this industry is un- certainty on consumer demand and that the industry depends on the availability of raw material from forest. There is a lack in supply in the average amount of 3.386.282 m3. The development of furniture industry needs to consider more the aspect of sustainability. Forest destruction is one of the parameters of environmental aspect, in which the decreasing rate of natural production forest and overall forest are 61,982 ha and 51,820 ha per year, respectively. Furthermore, as one of the economical aspects, the economical revenue achieved by this industry tends to constant. On the other hand, this industry can meet the consumer demand, representing the social aspect.ABSTRAKPerlu ada kajian untuk melihat dan memprediksi keberlanjutan pengembangan industri furniture Indonesia dengan melihat kepada 3 aspek, yaitu aspek ekonomi, aspek sosial dan aspek lingkungan, sebagai aspek utama dalam pengem- bangan supply chain management yang berkelanjutan. Penelitian ini diawali dengan identifikasi model dasar supply chain industri furniture. Selanjutnya, digambarkan potensi dan kelemahan yang ada, baik secara internal maupun ek- sternal, dengan menggunakan analisis SWOT (strength, weakness, opportunity, threat). Untuk melihat perilaku sistem dilakukan pemodelan dan simulasi. Hasil penelitian ini menunjukkan bahwa karakteristik industri furniture adalah ketidakpastian permintaan konsumen dan sangat tergantung pada kondisi hutan untuk menjamin ketersediaan pasokan kayu. Setiap tahun terjadi kekurangan pasokan rata-rata sebesar 3.386.282 m3 dibandingkan kebutuhannya. Pengem- bangan industri furniture masih kurang memperhatikan aspek keberlanjutan. Kerusakan hutan menjadi salah satu pa- rameter keberlanjutan aspek lingkungan dimana tingkat penurunan luas hutan produksi alam dan hutan keseluruhan berturut-turut adalah sebesar 61.982 ha dan 51.820 ha. Selain itu, dari aspek ekonomi, pendapatan (revenue) yang bisa dicapai oleh industri furniture cenderung tidak mengalami peningkatan. Di sisi lain, industri furniture Indonesia cukup baik dalam memenuhi kebutuhan konsumen, sebagai indikator aspek sosial.
