Cholesterol and Malondialdehyde Contents of Broiler-Chicken Meat Supplemented with Indigofera Zolingeriana Top Leaf Meal

This research aimed to increase functional value of broiler-chicken meat containing high antioxidant and low cholesterol through substitution of soybean meal (SBM) with Indigofera zollingeriana top leaf meal (ILM). The experiment used 160 day old broiler chicken (Cobb strain). The experimental chicken were provided dietary treatments when they were 15-days old (initial body weight of 460.5±1.56 g/bird) and terminated on day 35. A completely randomized design (CRD) with four treatments and four replications and ten birds in each replication was used in this experiment. Dietary treatments were: R1= diet containing 20% soybean meal (SBM) without I. zollingeriana top leaf meal (ILM); R2= diet containing 16% SBM and 5.9% ILM; R3= diet containing 12% SBM and 11.8% ILM; R4= diet containing 8% SBM and 17.74% ILM. Variables measured were performances (feed consumption, body weight gain, and feed conversion) and the quality of broiler meat (cholesterol, fat content, and malondialdehyde [MDA] concentration). The results showed that supplementation of 17.74% ILM (R4) as the substitution of 60% soybean meal protein produced the same performances of broilers as those of control diet (R1). Supplementation of 11.8% ILM as the substitution of 40% soybean meal protein (R3) decreased meat cholesterol by 34.70%, meat fat content by 52.93%, and MDA concentration by 62.52%. The conclusion of this study was that supplementation of 17.74% ILM produced the same performances as that of control diet, increased antioxidant content of the meat, indicated by a lower MDA concentration, and decreased cholesterol, as well as fat content of broiler-chicken meat

Evaluasi Kinerja Kegiatan Perawatan Mesin Injection Mold Menggunakan Metode Total Productive Maintenance (Tpm) Pada PT Ichikoh Indonesia

Penelitian ini bertujuan untuk memberikan gambaran deskriptif mengenai perawatan mesin atau maintenance, meliputi Total Productive Maintenance, Overall Equipment Effectiveness, Overall Human Ineffectiveness dan Six Big Losses pada PT Ichikoh Indonesia. Permasalahan yang terjadi diperusahaan yaitu banyaknya jumlah part defect dikarenakan mesin sering breakdown. Pengumpulan data dilakukan dengan observasi dan wawancara terstruktur dengan Manager Departement Molding Upstream 1 dan Departement Maintenance. Data tersebut dianalisis menggunakan metode kuantitatif dan evaluatif dari periode bulan April 2016 sampai Maret 2017. Dari hasil analisis ini PT Ichikoh Indonesia memiliki nilai efektifitas mesin yang masih dibawah standar JIPM (Japan Institude of Plant Maintenance) yaitu dengan nilai tertinggi pada bulan Februari 74%, sedangkan standar JIPM (Japan Institude of Plant Maintenance) adalah minimal sebesar 85% yang dihitung menggunakan metode Overall Equipment Effectiveness. Sedangkan untuk pengukuran tingkat ketidakefektifan kerja operator yang dianalisis menggunakan metode Overall Human Ineffectiveness mendapatkan nilai yang masih besar pada bulan May 2016 yaitu sebesar 17%. Faktor yang menyebabkan rendahnya nilai efektifitas mesin dan tingkat ketidakefektifan kinerja operator adalah faktor Idling and Minor Stoppagges dengan nilai losses sebesar 54% yang sudah dianalisis menggunakan diagram pareto. Sesuai dengan diagram sebab-akibat (fishbone) didapat faktor-faktor yang menyebabkan terjadinya Idling and Minor Stoppagges yang menjadi prioritas utama adalah a). faktor manusia yaitu masih kurang disiplin, sering terjadi kesalahan dalam perbaikan mesin, b). faktor material yaitu kesalahan spesifikasi material dan rendahnya perawatan bahan baku, c). faktor mesin yaitu mesin sering breakdown, kesalahan setup, d). faktor metode yaitu penjadwalan pengganti komponen yang belum efektif dan autonomous maintenance kurang berjalan dengan baik, e). faktor lingkungan yaitu kebersihan mesin kurang

Geometry induced entanglement transitions in nanostructures

We model quantum dot nanostructures using a one-dimensional system of two interacting electrons. We show that strong and rapid variations may be induced in the spatial entanglement by varying the nanostructure geometry. We investigate the position-space information entropy as an indicator of the entanglement in this system. We also consider the expectation value of the Coulomb interaction and the ratio of this expectation to the expectation of the confining potential and their link to the entanglement. We look at the first derivative of the entanglement and the position-space information entropy to infer information about a possible quantum phase transition.Comment: 3 pages, 2 figures, to appear in Journal of Applied Physic

Corrosion study of pipeline material for seabed sediment in tropical climate

Corrosive environments such as marine sediments can cause corrosion to steel pipelines at any time when certain conditions are met. Seabed sediment could cause severe corrosion damage due to its corrosiveness to the pipelines buried under it. Many consequences could take place in case if there is incident in oil/gas pipelines. Successfully identifying elements of corrosion in marine sediment would enhance the future of steel structure protection and monitoring systems. This article focuses on the behaviour of corrosion rate of steel located near shore environment and the aim is to determine the effect of sediment on corrosion of steel. To investigate that, simulated near shore sediment conditions have been used where the steel coupons buried in sediments which have different characteristics. Weight loss technique has been implemented to determine the weight loss rate of the steel specimens. Based on the results of this study, metal weight loss increases as the duration of exposure to seabed sediment environment become longer. The sea sediment simulated condition has given significant levels of corrosion. Conclusively, the corrosion rate of steel in seabed sediment located in tropical region is complicated and further studies are suggested

Production, Competition Indices, and Nutritive Values of Setaria Splendida, Centrosema Pubescens, and Clitoria Ternatea in Mixed Cropping Systems in Peatland

This research was conducted to evaluate production, different competition indices and nutritive value of Setaria splendida, Centrosema pubescens, and Clitoria ternatea in monoculture and mix cropping system on peat soil land. The experiment was set up in a randomized complete block design with five treatments and three replications. The five treatments were: S. splendida sole cropping (SS), C. pubescens sole cropping (CP), C. ternatea sole cropping (CT), S. splendida and C. pubescens mix cropping (SS/CP) and S. splendida/C. ternatea mix cropping (SS/CT). The DM yield of S. splendida in mixed cropping with C. pubescens increased 43.4% and in mix cropping with C. ternatea increased 15.7% compared to sole S. splendida. The value of land equivalent ratio of SS/CP (LERSS/CP) was >1. The LERSS/CT value was <1. The crowding coefficient value of S. splendida (KSS) was higher than KCP and KCT. The total value of KSS/CP and KSS/CT were >1. The competition ratio (CR) values of S. splendida in both mix cropping were >1. The agressivity (A) values of S. splendida in both mix cropping were positive. The crude protein, NDF and ADF content of forage were not affected by mix cropping system. In conclusion, mix cropping in peatland do not affect productivity and nutritive value of S. splendida, C. pubescens, and C. ternatea. S. splendida is more effective in exploiting environmental resources when intercropped with C. pubescens compared to C. ternatea on peatland
