PT. Prima Sejati Sejahtera as one of the subsidiaries of PT. Pan Brothers Tbk. which is engaged in garment production. The company's mechanical department in managing spare part inventory is still using intuitive method, where the number of spare part order for certain periods based on spare part demands data onto the previous period. The company’s mechanical department often stock out of spare parts. Spare part’s inventory management becomes a complex issue because of the need for fast response to handle the downtime of machines, and the risk of obsolescence of spare parts. So in this research will discuss about spare part inventory control which is started with spare parts grouping by using ABC analysis method to determine the appropriate inventory control method for each group. There are 23 spare parts which included in group A. The forecast of spare part’s demands to use Croston, Syntetos-Boylan Approximation (SBA) and Single Exponential Smoothing (SES). Comparison of each forecasting method will be determined by the value of forecasting errors (MAD). It is known that there are 12 spare parts with Croston method in the best forecasting method, 6 spare parts in Syntetos-Boylan Approximation (SBA) method and 5 spare parts with Single Exponential Smoothing (SES) method. Based on the best forecasting result, it will be calculated the value of safety stock (SS), reorder point (ROP) and the optimal number of ordering (Q) using Continuous Review method for each spare part.

Peta evakuasi sangat penting bagi suatu rumah sakit. Hal ini dikarenakan untuk mengurangi resiko saat terjadi bencana (gempa bumi) dan sebagai syarat akreditasi untuk memperoleh akreditasi suatu rumah sakit. Penelitian ini bertujuan untuk menyusun peta evakuasi dan penandaannya. Dengan perancangan peta evakuasi, diharapkan dapat terpenuhi salah satu syarat akreditasi rumah sakit dan memudahkan penghuni bangunan rumah sakit dalam mencari jalan tercepat saat keadaan darurat atau keadaan bahaya. Terdapat dua tahap dalam perancangan peta evakuasi. Tahap yang pertama ialah perancangan alur evakuasi dengan menggunakan Algoritma Floyd-Warshall untuk menentukan lintasan terpendek. Tahap kedua ialah penandaan peta evakuasi. Tahap pertama terdiri dari enam tahap, yaitu pembuatan block plan Rumah Sakit Umum Daerah Kabupaten Kebumen, penentuan letak titik berkumpul (assembly point), penentuan node, pemilahan titik berkumpul (assembly point) untuk masing-masing ruang, penentuan jarak masing-masing ruang ke titik berkumpul (assembly point), dan penentuan alternatif evakuasi. Tahap kedua merupakan perancangan penandaan peta evakuasi. Dalam hal ini, warna dan bahan penandaan peta evakuasi sesuai dengan Rumah Sakit Islam Surakarta. Penandaan peta evakuasi dibuat dari bahan acrlylic dan dipasang sepanjang jalur evakuasi. Hasil penelitian menunjukkan bahwa terdapat 40 ruang yang dapat langsung ditentukan lintasan evakuasinya dan 35 ruang ditentukan lintasan terpendeknya dengan menggunakan Algoritma Floyd-Warshall. Dari ketiga puluh lima ruang itu, 16 ruang menuju titik berkumpul sebelah utara, 5 ruang menuju titik berkumpul sebelah barat, dan 14 ruang menuju titik berkumpul sebelah selatan. Sehingga titik berkumpul sebelah utara menampung 39 ruang, titik berkumpul sebelah barat menampung 19 ruang, dan titik berkumpul sebelah selatan 17 ruang serta peta evakuasi telah disusun dan akan dipasang di tempat-tempat strategis sepanjang jalur evakuasi.

Performance measurement is important to business organization both manufacturing or service industry, and education. Performance measurement considers all activities and satisfies stakeholder’s requirements. The aim of his research is to design performance measurement in a Department in X University using Integrated Performance Measurement Systems (IPMS) method. IPMS is a performance measurement method that considers stakeholder’s requirements and measure performance integrally. IPMS method generates Key Performance Indicators (KPI) from stakeholder’s requirements by four steps, that are; identification of stakeholder’s requirements, development of external monitor, objectives establishment, and identification of KPs. Each of KPI has difference significance to performancemeasurement system. The significance of each KPI is counted by Analytical Hierarchy Process (AHP). This research results 7 performance measurement perspectives that consist of 15 objectives. The objectives can be measured by 57 KPI (consist of 43 main KPI and 24 sub KPI)

Perancangan Sistem Pengukuran Kinerja Organisasi Non Profit (Studi Kasus pada UTDC PMI Surakarta) Jauhari, Wakhid Ahmad; Liquiddanu, Eko; Nugraheni, Eka Agustina

In this paper we developed performance measurement system in UTDC PMI Surakarta. We used Integrated Performance Measurement System (IPMS) methodology which based on stackeholder’s requirement, to design the measurement system. From the design process, it can be identified 8 stakeholders, and based on stakeholder’s requirements, it can be obtained 27 requirements and 7 objectives. Furthermore, we developed 19 key performance indicators (KPIs) which can be classified into 6 aspects, including donor, human resources, blood preparation, output, administration, and control and evaluation.Finally, we conducted Analythic Hierarchy Process (AHP) method to weight the all aspects and KPIs. It was found that human resources(0.435) was most importance aspect and employee’s performance achievement (0.24) became most importance indicator among them.

Perancangan Ulang Tata Letak Fasilitas di PT. Dwi Komala dengan Metode Systematic Layout Planning Naganingrum, R. Pitaloka; Jauhari, Wakhid Ahmad; Herdiman, Lobes

PT. Dwi Komala is one of middle-scale industries that producing in footwear product. In production system, waste such as movement waste and excessive transportation, are commonly found and affect to unmet production target. This waste occurs because the work station placement does not consider the production process flow and spatial interconnectedness. One of solutions that can be done to repair the facility layout is redesigning the layout by considering production process flow and the relationship between any space in the layout. The layout of facilities in this company is not made based on the good planning but only adjusting with the existing space, so that irregular layout results. Meanwhile, the facility layout not taking into account the production process flow, production machineries placement and production activity requirement results in larger material handling cost and it will impact on the high production cost and production process time. For that reason, this research aims to produce the proposal of layout design that can minimize the material handling cost (MHC). In this research, the facility is redesigned using Systematic Layout Planning (SLP). The SLP procedure consists of three stages: analysis, adjustment and evaluation. The analysis stage includes material flow analysis, activity relationship chart (ARC), activity relationship diagram (ARD), area requirement analysis and available area analysis. The adjustment stage includes planning the spatial relationship diagram and alternative layout design. In evaluation stage, the evaluation was done on the alternative layout design. Three proposed layout which minimizes material handling cost could be resulted by Systematic Layout Planning (SLP) method. The first proposed layout gives a significant saving of 11.35% compare to existing layout. The second layout results in 31.17% saving while the last layout gives a saving of 32.44%. Thus, the third layout proposal was recommended as the selected layout proposal

Kenyamanan termal sangat berpengaruh terhadap proses produksi, kenyamanan termal itu sendiri salah satunya dipengaruhi oleh kelembaban udara. Penelitian ini bertujuan untuk mengetahui distribusi kelembaban udara pada lantai produksi IKMâ€ABCâ€ melalui pemetaan dengan software surfer dan untuk mengetahui tingkat kenyaman termal pekerja sesuai dengan Keputusan Menteri Kesehatan Republik Indonesia Nomor 1405/Menkes/SK/XI/2002. Metode yang digunakan dalam penelitian ini adalah pengambilan data kelembaban udara dengan pengamatan langsung sesuai dengan titik yang telah ditentukan dengan berdasarkan SNI 16-7062- 2004 yang nantinya akan diolah melalui software surfer. Dari penelitian ini didapatkan bahwa rata-rata kelembaban udara keseluruhan adalah sebesar 68.1% dan dari peta kontur didapakan bahwa tidak terdapat zona aman pada lantai produksi IKMâ€ABCâ€™ karena nilai kelembaban udara di semua area melebihi NAB yang telah ditentukan
