Judul: Penjadwalan Perawat Rsupn Dr. Cipto Mangunkusumo Lantai 4 Zona A Menggunakan Metode Fuzzy Goal Programming
Abstrak: Pemodelan penjadwalan perawat harus memperhatikan ketentuan dari peraturan rumah sakit. Dalam karya ilmiah ini masalah penjadwalan perawat akan diselesaikan menggunakan metode Fuzzy Goal Programming. Fungsi objektifnya ialah memaksimumkan derajat kepuasan fungsi keanggotaan dari setiap fungsi tujuan fuzzy. Penggunaan teori himpunan fuzzy menghilangkan kesulitan dalam menentukan ketidakpastian nilai target yang ingin dicapai pihak rumah sakit dan keinginan perawat sehingga dibuat selang interval yang memuat nilai minimum dan nilai maksimum target. Berdasarkan pemodelan ini diperoleh jadwal perawat dengan jumlah jam kerja dan hari kerja yang adil dan tidak ada pola libur masuk libur.

Judul: Penjadwalan Perawat Menggunakan Fuzzy Goal Programming: Studi Kasus di Rumah Sakit Hasanah Graha Afiah Depok
Abstrak: Rumah sakit seringkali masih menggunakan cara manual dalam menyelesaikan masalah penjadwalan perawat. Cara seperti ini kurang efisien dan rentan terhadap kesalahan saat melibatkan jumlah perawat yang relatif besar. Tujuan karya ilmiah ini ialah memodelkan masalah penjadwalan perawat menggunakan metode fuzzy goal programming. Fungsi objektifnya yaitu memaksimumkan derajat kepuasan fungsi keanggotaan dari setiap fungsi tujuan fuzzy. Berdasarkan pemodelan ini diperoleh jadwal perawat dengan jumlah hari kerja dan jumlah shift yang didapat setiap perawat yang lebih baik dan tidak ada pola libur masuk libur. Kata kunci: fuzzy goal programming, pemodelan, penjadwalan, perawat., Hospitals often still use manual methods in solving nurse scheduling problems. This method is less efficient and prone to errors when involving a relatively large number of nurses. The purpose of this scientific paper is to model the problem of scheduling nurses using the fuzzy goal programming method. The objective function is to maximize the degree of satisfaction of the membership function of each fuzzy goal function. Based on this modeling, nurses' schedules with the number of working days and the number of shifts each nurse gets are better and there is no pattern of holidays in the holidays.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
