Authors: Dewi Putri Sari , Saroso Dana Santoso 
Published: March 2017

Semakin berkembangnya dunia industri perusahaan manufaktur membuat semakin ketatnya persaingan pasar untuk mencukupi kebutuhan konsumen. Selain itu perusahaan juga dituntut untuk dapat memuaskan konsumen dengan cara menyelesaikan pesanan konsumen tepat pada waktunya. Sehingga perlu ditunjang oleh sistem produksi yag efisien. Untuk dapat menciptakan sistem produksi yang efisien maka diperlukan suatu perencanaan yang baik. Peramalan dan perencanaan material untuk box panel menjadi alasan yang kuat untuk meminimalkan stok gudang, khususnya PT. TIS. Adapun untuk perencanaan persediaan material box panel tersebut memerlukan peramalan yang optimal dengan memafaatkan metode Simple Moving Average (SMA) dan Single Exponential Smoothing (SES). Dengan membandingkan kedua metode tersebut dihasilkan data bahwa dengan metode Simple Moving Average menghasilkan nilai eror (MAD dan MSE) paling kecil, yaitu sebesar MAD 7,3 dan MSE 72. Sedangkan untuk perencanaan material menggunakan metode MRP Lot for Lot (LFL) dan Fixed Order Quantity (FOQ). Hasil perbandingan kedua metode tersebut menghasilan sistem Lot for Lot lebih efisien dan sesuai diterapkan pada PT. TIS karena total biaya persediaan minimum, yaitu sebesar Rp 199.692.470.

Abstract - Magnesium and magnesium alloys is one of materials that worldwide used on automotive components due to very good strength to weight ratio, resistant to corrosion, lighter compare to steel materials. Other than that magnesium has an advantage in easy to form and good machinability. Nevertheless, magnesium known as metal which is easy to burned because of magnesium has low melting point. To maintain magnesium from burning quickly when proses machining, it needs to use coolant or lubricant to reduce temperature. Using of coolant when machining process can reduce temperature on cutting tool and work piece material, while using of lubricant can reduce friction between the cutting tool and work piece mateial. However, using of coolant and lubricant can harm for the environment and also coolant difficult to destroyed. Therefore, an alternative method to reduce the temperature when machining of magnesium alloy is using the rotary cutting tool system. In the rotary cutting tool system, the cutting tool has a time to experience cooling in the period time. Other than aspect of temperature, surface roughness values are representative of surface of quality of produced componens. In this research, surface roughness value of magnesium alloy of AZ31 observed in ranges of work piece cutting speed of (Vw) 25, 50, 120, 160, 200 m/min, rotary cutting speed of (Vt) 25, 50, 75 m/min, feed rate of (f) 0,05 and 0,10 mm/rev, and depth of cut of 0.2 mm. The turning process was done by using two kinds of diameter of rotary cutting tools are 16 and 20 mm, and without applying of coolant. The results of the research showed that the minimum surface roughness value of machined surface was 0,62𝝻m by using insert with diameter of 16 mm, while the maximum surface roughness value of machined surface was 2,86 𝝻m by using insert with diameter of 20 mm. This result stated that the increase in the diameter of rotary cutting tool gives a significant effect on the produced surface roughness value. Factor of feed rate also gives a significant contribution on the surface roughness value of machined magnesium surface. The increase in feed rate generated significantly surface roughness value as long as the trials experiments. The produced surface roughness values inversely proportional to the cutting speed of rotary cutting tool.Keywords - magnesium, rotary tool, surface roughness, turning.
ANALISIS PENGELOLAAN HUTAN KEMASYARAKATAN DI SEKITAR KAWASAN HUTAN LINDUNG REGISTER 30 KABUPATEN TANGGAMUS PROVINSI LAMPUNG TAHUN 2010

Hutan kemasyarakatan (Hkm) adalah hutan negara yang pemanfaatan utamanya ditujukan untuk memberdayakan masyarakat setempat. Kebijakan Hutan kemasyarakatan mengizinkan masyarakat untuk dapat mengelola sebagian dari sumberdaya hutan dengan rambu-rambu yang telah ditentukan Permintaan dari kelompok-kelompok petani hutankemasyarakatan mengenai perizinan Hkm di sekitar kawasan hutan lindung register 30 Tanggamus sangat tinggi dan banyak tumbuh kelompok-kelompok baru yang merupakan kelompok-kelompok potensial menjadi kelompok pengelola Hkm yang bagus. Namun kenyataannya banyak kelompok tani yang belum memperoleh izin pengelolaan Hkm bahkan ada kelompok tani yang tidak mampu membuat draft/proposal izin pengelolaan Hkm, Dari 38 kelompok tani yang mengajukan izin, baru 14 kelompok tani yang telah memperoleh izin pengelolaan HKm, sedangkan kelompok tani lainnya ada yang masih tahap verifikasi, namun ada juga yang tidak jelas sampai sejauh mana proses perizinan tersebut berlangsung. Kondisi tersebut jelas merupakan suatu masalah, karena belum didapatnya izin pengelolaan Hkm tidak hanya mengakibatkan petani sekitar kawasan hutan tidak dapat memanfaatkan hutan sebagai penyangga kehidupan ekonomi, sosial dan ekologis mereka, namun akibat lebih jauh adalah ketika kelompok tani tidak mampu berfungsi sebagai pengelola fungsi hutan yang optimal bahkan ketika akhir-akhir ini banyak terjadi alih fungsi hutan yang tidak sesuai peruntukan dan penggunaan lahannya.Tujuan penelitian adalah pertama, mengidentifikasi kendala apa saja yangdihadapi kelompok tani register 30 Kabupaten Tanggamus sehingga belum dapat membuat atau memperoleh izin Hutan Kemasyarakatan, dan kedua, mengetahui faktor-faktor pendukung untuk melakukan percepatan proses pengajuan perizinan Hkm di kawasan hutan register 30 Kabupaten Tanggamus. Melalui FGD dan wawancara dengan petani, aparat masyarakat, tokoh masyarakat, Watala dan Dinas Kehutanan diperoleh hasil bahwa kendala yang dihadapi kelompok tani di register 30 adalah adanya keterbatasan pengetahuan petani tentang proses/ tatacara pengajuan izin pengelolaan Hkm, terbatasnya tenaga fasilitator, dan adanya “oknum” (elit desa, LSM dan bahkan aparat pemerintah) yang justru memanfaatkan kebijakan Hkm untuk mencari keuntungan sepihak. Faktor pendukung percepatan proses pengajuanperizinan Hkm di register 30 adalah melalui kegiatan pendampingan masyarakat/fasilitasi kepada kelompok tani dan pengemasan pesan dan pembuatan draft buku panduan Hkm.

Computed tomographic evaluation of femoral and tibial conformation in English Staffordshire Bull Terriers with and without congenital medial patellar luxation
Authors: Voss Katja , Newman Mark 
Published: March 2017

SummaryObjective: To compare hindlimb conformation of English Staffordshire Bull Terriers with and without medial patellar luxation using computed tomography.Methods: Hindlimb computed tomography (CT) was performed on six English Staffordshire Bull Terriers with grade II or III medial patellar luxation, and six without medial patellar luxation. Inclination angle, femoral condyle trochanteric angle, anteversion angle (AA), distal anteversion angle (DAA), proximal anteversion angle (PAA), femoral varus angle (FVA), tibial valgus angle (TVA), and tibial torsion angle (TTA) were measured. Student’s T-test was conducted to compare normal limbs to limbs with medial patellar luxation, all limbs of dogs with medial patellar luxation to limbs of the control group, and medial patellar luxation affected limbs (normal limbs of unilaterally affected dogs excluded) to the control group. P-values less than 0.05 were considered significant.Results: Two dogs with medial patellar luxation were only affected unilaterally. Limbs of English Staffordshire Bull Terriers with medial patellar luxation had significantly diminished AA and DAA, in addition to decreased TVA. These differences were similar regardless of how the unaffected limbs from affected dogs were treated in our analysis.Discussion and conclusion: Medial patellar luxation in this population of English Staffordshire Bull Terriers was characterized by a decrease in femoral anteversion, external rotation of the femoral diaphysis, and decreased tibial valgus. These findings may help inform clinical decision making when performing osteotomy for treatment of medial patellar luxation in this breed.

Abstract
Azacitidine (AzaC) mitigates graft-versus-host disease (GvHD) in both murine preclinical transplant models and in human clinical trials while maintaining a robust graft-versus-leukemia effect. Previous studies have failed to investigate the role of natural regulatory T cells (nTregs) on the mitigation of GvHD by AzaC, instead focusing on the generation of suppressive Tregs (CD4+CD25+FOXP3+) through the in vivo conversion of alloreactive donor T effectors (Teffs; CD4+CD25−FOXP3−) and the direct antiproliferative effects of AzaC on allogeneic T cells. Using B6.Foxp3DTR/GFP mice in which Tregs can be specifically ablated through administration of diphtheria toxin, we demonstrate that natural Tregs are required in the donor graft for AzaC to optimally protect against GvHD and that nTregs, unlike Teffs (CD3+FOXP3−), are resistant to the antiproliferative effects of AzaC. Gene expression analysis identified the potent cell cycle inhibitor, p21, was significantly upregulated in Teffs but not nTregs after treatment with AzaC. Furthermore, we demonstrate that Teffs deficient in p21 are less sensitive to the antiproliferative effects of AzaC. These results demonstrate that nTregs are essential for AzaC to fully protect against GvHD and have important clinical implications for future clinical trials testing AzaC as a novel method of GvHD prophylaxis in man.

Abstract
The recent association between Zika virus (ZIKV) and neurologic complications, including Guillain-Barré syndrome in adults and CNS abnormalities in fetuses, highlights the importance in understanding the immunological mechanisms controlling this emerging infection. Studies have indicated that ZIKV evades the human type I IFN response, suggesting a role for the adaptive immune response in resolving infection. However, the inability of ZIKV to antagonize the mouse IFN response renders the virus highly susceptible to circulating IFN in murine models. Thus, as we show in this article, although wild-type C57BL/6 mice mount cell-mediated and humoral adaptive immune responses to ZIKV, these responses were not required to prevent disease. However, when the type I IFN response of mice was suppressed, then the adaptive immune responses became critical. For example, when type I IFN signaling was blocked by Abs in Rag1−/− mice, the mice showed dramatic weight loss and ZIKV infection in the brain and testes. This phenotype was not observed in Ig-treated Rag1−/− mice or wild-type mice treated with anti–type I IFNR alone. Furthermore, we found that the CD8+ T cell responses of pregnant mice to ZIKV infection were diminished compared with nonpregnant mice. It is possible that diminished cell-mediated immunity during pregnancy could increase virus spread to the fetus. These results demonstrate an important role for the adaptive immune response in the control of ZIKV infection and imply that vaccination may prevent ZIKV-related disease, particularly when the type I IFN response is suppressed as it is in humans.

Abstract
The cytokine IL-22 plays a critical role in mucosal barrier defense, but the mechanisms that promote IL-22 expression in the human intestine remain poorly understood. As human microbe–responsive Vγ9/Vδ2 T cells are abundant in the gut and recognize microbiota-associated metabolites, we assessed their potential to induce IL-22 expression by intestinal CD4+ T cells. Vγ9/Vδ2 T cells with characteristics of APCs were generated from human blood and intestinal organ cultures, then cocultured with naive and memory CD4+ T cells obtained from human blood or the colon. The potency of blood and intestinal γδ T-APCs was compared with that of monocytes and dendritic cells, by assessing CD4+ T cell phenotypes and proliferation as well as cytokine and transcription factor profiles. Vγ9/Vδ2 T cells in human blood, colon, and terminal ileum acquired APC functions upon microbial activation in the presence of microenvironmental signals including IL-15, and were capable of polarizing both blood and colonic CD4+ T cells toward distinct effector fates. Unlike monocytes or dendritic cells, gut-homing γδ T-APCs employed an IL-6 independent mechanism to stimulate CD4+ T cell expression of IL-22 without upregulating IL-17. In human intestinal organ cultures, microbial activation of Vγ9/Vδ2 T cells promoted mucosal secretion of IL-22 and ICOSL/TNF-α–dependent release of the IL-22 inducible antimicrobial protein calprotectin without modulating IL-17 expression. In conclusion, human γδ T-APCs stimulate CD4+ T cell responses distinct from those induced by myeloid APCs to promote local barrier defense via mucosal release of IL-22 and calprotectin. Targeting of γδ T-APC functions may lead to the development of novel gut-directed immunotherapies and vaccines.
Infection prevention and control measures currently applied in South African audiology
Authors: Ehlert Katerina , Naude Alida M. 
Published: March 2017

Background: To counter the global increase in infection-related deaths, infection control has recently developed into an active area of research. Many diseases can be prevented by infection control. In the confines of the audiology clinic, cross-contamination by micro-organisms associated with opportunistic infections remains a real concern.Objective: The primary aim of the study was to ascertain the methods that audiologists in South Africa use to prevent and control the spread of infections during and after consultation with clients.Method: A survey study was conducted, using a self-administered questionnaire. Fifty currently practising audiologists participated in the study.Results: The majority (84%; n = 42) of respondents acknowledged the importance of hand hygiene for the purpose of infection control, with 76% (n = 38) making use of no-rinse hand sanitisers. Approximately a third of audiologists wear gloves during procedures such as otoscopy and immittance, and while handling hearing aids. Disinfecting audiological equipment seem to be the preferred choice of infection control, with only 60% (n = 30) of respondents sterilising audiological equipment after each individual patient consultation. Less than half of the respondents disinfected touch surfaces and toys in the reception area.Conclusions: Based on the results, further education and training should focus on measures implemented in infection control, awareness of possible risk factors at work settings, and vaccination as an effective means of infection control.

Published: March 2017

Abstract
Aims and Objectives: In an attempt to avoid the high morbidity and mortality associated with exploratory laparotomy in a patient of duodenal ulcer perforation (DUP), an attempt was made to treat patients with spontaneous DUP with endoscopic clips. Background: DUP is a common cause of surgical emergency. Traditional form of treatment includes nasogastric decompression, fluid resuscitation, and exploratory laparotomy or laparoscopy for repair. Considering the compromised state of such patients, endoscopic treatment and avoiding surgery will play a great role in preventing the further stress caused by surgery and facilitate quicker recovery. On thorough review of literature, we found few articles stating successful endoscopic clipping of iatrogenic duodenal perforation occurred during upper endoscopy. Our case series appears to be first of its kind reporting the use of endoclips for treating spontaneous (noniatrogenic) DUP. Materials and Methods: Three young male patients presenting with a short duration history of abdominal pain and vomiting and chest radiograph suggesting pneumoperitoneum were selected for endoscopic clipping. All of them were hemodynamically stable with near normal blood pressure and pulse rate. Under local anesthetic spray and mild sedation, endoscopic clipping was carried out along with supportive treatment. Postoperatively, patients were monitored clinically and radiographically and discharged after they could tolerate full diet. Results and Conclusion: We recommend that in selected group of young patients of DUP who have presented early and are hemodynamically stable, endoclips may be applied to approximate mucosa. With supportive conservative treatment offered, thereafter healing of perforation occurs without the need for laparotomy or laparoscopy for suturing the same.

Abstract. In this paper we investigate the potential of melt pond fraction retrieval from X-band polarimetric synthetic aperture radar (SAR) on drifting first-year sea ice. Melt pond fractions retrieved from a helicopter-borne camera system were compared to polarimetric features extracted from four dual-polarimetric X-band SAR scenes, revealing significant relationships. The correlations were strongly dependent on wind speed and SAR incidence angle. Co-polarisation ratio was found to be the most promising SAR feature for melt pond fraction estimation at intermediate wind speeds (6. 2 m s−1), with a Spearman's correlation coefficient of 0. 46. At low wind speeds (0. 6 m s−1), this relation disappeared due to low backscatter from the melt ponds, and backscatter VV-polarisation intensity had the strongest relationship to melt pond fraction with a correlation coefficient of −0. 53. To further investigate these relations, regression fits were made both for the intermediate (R2fit = 0. 21) and low (R2fit = 0. 26) wind case, and the fits were tested on the satellite scenes in the study. The regression fits gave good estimates of mean melt pond fraction for the full satellite scenes, with less than 4 % from a similar statistics derived from analysis of low-altitude imagery captured during helicopter ice-survey flights in the study area. A smoothing window of 51 × 51 pixels gave the best reproduction of the width of the melt pond fraction distribution. A considerable part of the backscatter signal was below the noise floor at SAR incidence angles above  ∼  40°, restricting the information gain from polarimetric features above this threshold. Compared to previous studies in C-band, limitations concerning wind speed and noise floor set stricter constraints on melt pond fraction retrieval in X-band. Despite this, our findings suggest new possibilities in melt pond fraction estimation from X-band SAR, opening for expanded monitoring of melt ponds during melt season in the future.
