Judul: Analisis Beban Kerja pada Proses Pembuatan Crankcase dan Penerapan TBP untuk Memprediksi Cost Reduction di PT. Toyota Motor Manufacturing Indonesia
Abstrak: Toyota Business Practice is a way to apply the Toyota Way clearly at work everyday with the basic concept is a method to solve the problem. Toyota Business Practice consists of 8 steps, there are problem clarification, breakdown analysis, target setting, root cause analysis, countermeasures, see countermeasures through, evaluation, Standardization. Toyota Business Practice used to analyze the Cost Reduction activities. By using analysis of Toyota Business Practice found that the interior and electrical section is a major section of CR less with specification resin material for supplier Sugity. Based on the analysis known that to get the CR affected by materials and processes (manufacturing). In the workload analysis, for measurement by measuring heart rate during calibration step test and work. Measurements were done in CC 2TR and CC 1TR. In the measurement of operator CC 2TR taken four subjects, whereas operator CC 1TR taken two subjects. The first, measurements of heart rate during the calibration step test and the values obtained Increase Ratio of Heart Rate and Work Energy Cost-step test. Second, heart rate measurements were taken while working to get the value of Work Energy Cost and Total Energy Cost. From the measurement results obtained subject A, B, D (at 07:30-12:00) including categories of workload being, (at 12:30-16:00) heavy workload categories. On measurements during the month of Ramadhan for subjects C, E, F (at 07:30-12:00) including categories of workload being, subject C (at 12:30-16:00) category workload is very heavy-weight, subjects E, F categories of workload being.

Judul: Study work time and productivity of avanza assembly process at trimming 0 PT. Toyota Motor Manufacturing Indonesia
Abstrak: Assessment of work time and productivity should be done routinely by a company. One of the aims is to monitor whether the standard work time can still be used or need adjustment. This is important since PT. Toyota Motor Manufacturing Indonesia, the Indonesia's largest automotive company, has a high production target of 150,000 units of vehicles per year. Assessment of work time begins with the measurement of actual work time. From the measurement of actual working time, normal time and standard time for each activities were then caculated. Afterward, the utilization rate of time and productivity were calculated from the existing standard time and from the calculated standard time. In measurement of work time for preparations of RR Axle Avanza in Trimming 0 activities, Assembly Production Department in Karawang Plant, it was found that the operator had a 71 seconds lack time from 15 activities, while having 202 seconds remaining time from 22 activities. The utilization rate the existing standard time was 73,53% and the productivity was 7,27 units/hour. After the calculation of new standard time, it was obtained that the utilization rate was 87,3% and the productivity was 8,63 unit/hour with 53 seconds unutilized time and no lack time. This shows that the new standard time can be used as a guidance for preparations of RR Axle Avanza activities.

Judul: Infeksi leucocytozoon Smithi (Laveran dan Lucet, 1905) pada kalkun
Abstrak: Leucocytozoon smithi adalah parasit darah yang menyebabkan leucocytozoonosis pada kalkun, dan termasuk dalam genus Leucocytozoon yang perkembangan skizogoninya terja- di dalam sel-sel endotel dan sel-sel parenkhim hati, jan- tung, ginjal dan organ-organ lain dari unggas. Genus ini menghasilkan skizon yang besar. Gametogoninya terjadi di dalam sel-sel darah dan sel yang terinfeksi dapat berubah bentuk dan mengambil bentuk kumparan. Parasit ini tidak menghasilkan pigmen dan ditularkan oleh lalat penghisap darah dari genus Simulium. Infeksi kalkun terjadi pada saat sporozoit masuk ke dalam peredaran darah dan selanjutnya masuk ke dalam sel- sel parenkhim hati. Siklus hidupnya mirip dengan siklus hidup L. simondi seperti yang diuraikan di bawah ini. Skizogoni yang terjadi di dalam hati menghasilkan skizon hepatik. Skizon hepatik dewasa menghasilkan merozoit dan sinsitia. Merozoit dari skizon hepatik memasuki eritroblas dan eritrosit dan membentuk gametosit bulat, sedangkan sinsitianya dapat masuk ke dalam sel-sel RES dan kemudian membentuk megaloskizon. Megaloskizon dewasa menghasilkan merozoit yang kemudian masuk ke dalam limfosit dan leukosit lain membentuk gametosit memanjang. Gametositgametosit ini akan menjadi makrogametosit dan mikrogametosit. Perkembangan parasit dalam tubuh vektor (Simulium), segera dimulai setelah vektor menghisap darah kalkun yang mengandung gametosit ini. Dalam tubuh vektor ini akan ter- jadi pembuahan makrogamet oleh mikrogamet (tahap gametogoni). Dari pembuahan ini dihasilkan zigot yang bergerak (ookinet). Ookinet akan masuk dinding usus vektor untuk memulai tahap sporogoni yang menghasilkan sporozoit. Sporozoit ini akan menuju ke kelenjar ludah dan dari sini dapat dipindahkan lagi ke tubuh kalkun pada saat vektor menghisap darah. Vektor untuk L. smithi adalah S. occidentale, S. nigroparvum, S. slossonae, S. nigritarse. L. smithi berbahaya, terutama bagi kalkun-kalkun muda. Mortalitasnya dapat mencapai 90 persen. Gejala klinis yang ditimbulkannya antara lain anorexia, lemas dan cenderung untuk duduk, kekurusan dan kelemahan, sesak nafas dan in- koordinasi dan terjungkal terlihat pada stadium akhir dan selanjutnya kalkun mengalami coma kemudian mati…dst
