"ABSTRAKThe scarcity of blood that is still happening today is the result of a combination of high blood needs and the difficulty of recruiting and maintaining donors. There is no research discover the substitute that can replace the role of blood, therefore the only source is from donations or blood donors. Approximately 80% of total blood donations collected by American Red Cross are come from blood drive events. Because blood has 6-hour spoilage time, donated blood at various donation locations must be collected and sent to a blood center for processing in less than 6 hours. This research study the Maximum Blood Collection Routing Problem (MBCRP). This problem is the extension of Vehicle Routing Problem with Time-Window (VRPTW) by considering the spoilage time limitation in blood. A mathematical model with objective to maximize total blood collection is built to cope with this problem. The mathematical model will be tested for verification and validation. The model is written in a computer programming language using AMPL software and is solved using the CPLEX solver. Furthermore, the results of verification and validation tests will be evaluated to see the applicability of the model."

"ABSTRAKAmerican Dream adalah etos nasional dari negara Amerika Serikat; sebuah konsep dimana semua orang bisa menjadi sukses di Amerika Serikat jika bekerja keras. Meskipun terkesan positif, sisi lain dari American Dream yang bisa menjadi berbahaya bagi orang-orang yang mempercayainya sering menjadi tema dari banyak karya literatur dan film. Penelitian ini mencoba untuk menganalisis There Will Be Blood, sebuah film karya sutradara Paul Thomas Anderson yang dirilis tahun 2007, sebagai kritik kepada konsep American Dream. Hasil dari penelitian ini menunjukkan bahwa film There Will Be Blood ini menunjukkan konsep American Dream itu tidak seideal kelihatannya

ABSTRACTThe American Dream is the national ethos of the United States; a dream that everyone has a chance to success through hard work. The possibility that the pursuit of American Dream can be dangerous and lethal is used as a recurring theme in many literature works and films. This paper attempts to analyze There Will Be Blood, a 2007 film by Paul Thomas Anderson, as a critique to American Dream concept. This research will use James Truslow Adams definition of American Dream as a framework. The result of the study shows that the concept of American Dream is not as ideal as it seems in the movie There Will Be Blood."

"Transfusi darah autologous (TDA) adalah jenis transfusi darah paling aman baik untuk operator maupun pasien. Sedangkan teknik donasi pre operatif merupakan salah satu teknik TDA yang telah berhasil menurunkan permintaan darah homologous dengan sukses. Transfusi darah homologous (TDH) lebih banyak mempunyai risiko terjadinya komplikasi seperti penularan penyakit, reaksi anafilaktik, reaksi hemolitik dsb. Penelitian ini merupakan suatu uji paralel, membandingkan kelompok yang memperoleh TDA dengan kelompok yang memperoleh TDH pada operasi tulang belakang. Parameter yang digunakan adalah nilai hemoglobin(Hb) dan hematokrit(Ht) pre operasi (pasca donasi pada TDA), nilai Hb dan Ht pasca transfusi dan jumlah hari perawatan pasca operasi. Penelitian ini juga untuk mengetahui keberhasilan penggunaan TDA dilihat dari jumlah pasien yang akhirnya menggunakan TDH tambahan. Sampel adalah 74 pasien orthopaedi yang akan menjalani operasi tulang belakang dengan diagnosis fraktur, spondilitis TB, scoliosis, spinal stenosis dan spondilolisthesis. Pada kelompok TDA usia pasien 33,9 ± 14 tahun, sedangkan pada TDH 29,1 ± 11,5 tahun. Berat badan pemakai TDA 55,3 ± 11,1 kg dan pemakai TDH 52,8 ± 9,7 kg. Jumlah donasi pre operatif pada pemakai TDA 798,6 ± 170 cc. Ada 12 pasien (32,4%) yang jumlah donasi pre operatifnya tidak sesuai dengan permintaan. Pada kelompok pemakai TDA, ada delapan pasien (21,6%) yang akhirnya memerlukan tambahan TDH rata-rata 550 cc. Ada tiga pasien (8,1%) dari pemakai TDA mendapatkan transfusi yang tidak sesuai dengan indikasi (perdarahan < 15% dari total blood volume). Nilai Hb dan Ht pre operasi (pasca donasi) pada pemakai TDA secara bermakna (p=0,001) lebih rendah daripada pemakai TDH. Nilai Hb pasca transfusi pada pemakai TDA secara tidak bermakna (p=0,30) lebih rendah daripada pemakai TDH. Jumlah hari perawatan pasca operasi secara bermakna (p=0,000) lebih tinggi pada pemakai TDH dibanding pemakai TDA. Dapat disimpulkan bahwa : ada 21,6% dari pemakai TDA dengan teknik donasi pre operatif yang akhirnya memrlukan TDH tambahan; tidak ada perbedaan yang bermakna Hb, Ht pre operasi dan pasca transfusi pada pemakai TDA dan TDH; jumlah hari perawatan pasca operasi secara bermakna lebih tinggi pada pemakai TDH dibanding pemakai TDA.

Autologous Blood Transfusion (ABT) is the safest type of blood transfusion for the operator and the patient. The preoperative donation technique had already been reduced the homologous blood requirements successfully. Homologous Blood Transfusion (HBT) brings more risks in complications such as transmission of diseases, anaphylactic reactions, haemolitic reactions etc. This was a parallel study, comparing one group receiving ABT and a second group receiving HBT where in both groups were performed spine surgery. The parameter used was the hemoglobin(Hb) and hematocrit(Ht) content preoperatively (after donation of ABT) and after transfusion, total days in hospitalization after surgery. Another purpose of this study was also to achieve understandings in using ABT by considering the total patients who finally required additional HBT. There were 74 patients with diagnosis of spine fracture, tuberculous spondylitis, scoliosis, spinal stenosis and spondylolisthesis. In the ABT group the average age was 33,9 ± 14 years old and the HBT group was 29,1 ± 11,5 years old. Both groups consisted of 21 males and 16 females. Body weight of the ABT group was 55,3 ± 11,1 kg and the HBT group 52,8 ± 9,7 kg. Amount of donations preoperatively in ABT was 798,6 ± 170 cc. There were 12 patients (32,4%) where the donated blood amount preoperatively did not match up the requests. There were eight patients (21,6%) in the ABT group that required additional HBT of about 550 cc. Three patients (8,1%) of the ABT group received transfusion that did not match the indications (blood loss < 15% of the total blood volume). The Hb and Ht content preoperatively (after donation) of the ABT group significantly was less than the HBT group (p= 0,001). Hb content after transfusion in the ABT group was not significantly less than the HBT group (p = 0,30). Hospitalization days after surgery were significantly higher in the HBT group (p = 0,000). In conclusions : there was 21,6% of the ABT group with the preoperative donation technique that finally required additional HBT. Also there was no difference in the Hb and Ht content preoperatively and post transfusion in the ABT and HBT group, whereas hospitalization days after surgery were higher in the group receiving HBT than in the group receiving ABT.

Blood is an irreplaceable resource. According to Hall (2013), at University Hospitals of Leicester UK, from 507 units of crossmatched blood, only 283 units were used. There is 25% discharge blood at Guyana Public Hospital (Kurup, 2016). This research is a descriptive case study with qualitative method. Based on the analysis, 35.79% of the blood units were not transfused, the CT ratio was 2.12 (from 3536 unit of crossmatched blood, only 1670 unit were transfused). The cause of blood wastage is expired 98.4%, blood tube runs out, blood bag leak, blood damaged and unidentified causes. The use of MSBOS may decrease the rate of blood units wastage in elective surgery patients by 35.64%."

"Latar belakang. Komponen darah washed erythrocyte (WE) mempunyai fungsi yang sama dengan leukodepleted PRC (LD-PRC) yaitu untuk mencegah atau mengurangi reaksi transfusi. Namun banyak kekhawatiran para klinisi tentang cara pembuatan komponen darah WE dan bahan yang terkandung pada filter leukosit untuk menangkap leukosit. Tujuan utama dari penelitian ini adalah memberikan bukti secara ilmiah akan keamanan dalam pemakaian komponen darah PRC yang telah dimodifikasi ini dan juga memberikan pemahaman tentang pemakaian yang benar untuk komponen darah ini. Metoda. Penelitian ini menggunakan desain potong lintang pada 52 sampel darah. Pemeriksaan darah dilakukan pada 26 sampel WE sebelum dan sesudah menjadi komponen darah WE dan 26 sampel LD-PRC sebelum dan sesudah menjadi komponen darah LD-PRC. Pemeriksaan hematologi diperiksa secara otomatis menggunakan Sysmex Xn-2000, total protein diperkirakan menggunakan ADVIA 1650/1800, sedangkan hemolisis darah diamati menggunakan uji Osmotic Fragility Test (OFT). Hasil. Menunjukan kadar hemoglobin pada kelompok WE berkurang 15,4%, volume hematokrit menurun 8,55%, kadar protein menurun 98,4 %, dan jumlah leukosit menurun 87,31% dibandingkan dengan kelompok PRC sebelum dicuci. Selain itu, kadar hemoglobin dari komponen darah leukodepleted menurun 29,1%, volume hematokrit meningkat 21%, kadar protein menurun 79,1% dan jumlah leukosit menurun 99,9% dibandingkan dengan kelompok WB sebelum dijadikan komponen leukodepleted PRC. Persentase hemolisis pada komponen darah WE dan LD-PRC adalah < 0,8%. Perbedaan bermakna komponen darah WE dan LD-PRC dapat diamati pada parameter penilaian protein sisa dan leukosit sisa (p<0,05). Simpulan. Dalam pembuatan komponen darah WE protein plasma berkurang sebanyak 98,4%, sedangkan dalam pembuatan leukodepleted PRC, jumlah leukosit berkurang sebanyak 99,97%. Terjadinya hemolisis dapat diabaikan karena pada kedua komponen darah, hemolisis terjadi < 0,8%. Jika diperlukan komponen darah dengan kandungan protein plasma yang sedikit dapat digunakan komponen darah WE, sementara itu jika diperlukan komponen darah dengan jumlah leukositnya sedikit dapat digunakan/dipilih komponen darah leukodepleted.

Background. Washed erythrocyte (WE) and leukodepleted erythrocyte (LD-PRC) are normally used in clinical transfusion to prevent transfusion reaction. However, clinicians are wondering on the safety of those two blood components. The open system with saline for erythrocyte washing and the use of filter for blood leukodepletion still leave quiries on the possibility of hemolysis and their effectiveness for clinical transfusion. This study aims to provide scientific reasoning and the appropriate use of WE and leukodepleted blood respectively.

Methods. A cross sectional approach was employed in this study on two groups of blood component consisting of 52 blood samples each , i.e. WE and LD-PRC respectively. Blood examinations were carried out on 26 WE samples prior to and after washing and on 26 LD-PRC samples prior to and after leukodepletion. Blood indices were examined automatically using Sysmex Xn-2000, total protein was estimated using ADVIA 1650/1800, while blood hemolysis was observed employing Osmotic Fragility Test (OFT).

Results. It was shown that hemoglobin concentration of WE group decreased by 15.4%, hematocrit volume decreased by 8.55%, protein concentration decreased by 98.4%, and leukocyte count decreased by 87.3% compared to those the original Packed Red Cells. In addition, it was shown that the hemoglobin concentration of the leucodepleted blood component decreased by 29.1%, hematocrit volume increased by 21%, protein concentrations decreased 79.1% and the leukocyte count decreased by 99.9%. All the sampel of the WE blood products and all the LD-PRC blood sampel has hemolysis level <0,8%. However, a significant difference in protein concentration and leukocyte count was observed betwen WE and LD-PRC (p<0.05).

Conclusion. The process of erythrocytes’ washing decreased the plasma protein concentration by 98.4%, whilst the process of leucodepletion decreased the leucocyte count by 99.97%. Hemolysis during the preparation of both blood components could be negligible. It is concluded that WE blood component is preferable for transfusion when low plasma protein is required. On the other hand, leukodepleted PRC is preferable when blood component with low in leucocyte count is required."
