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: 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: Koksidiosis Pada Usus Halus Kelinci Yang Disebabkan Oleh Eimeria magna
Abstrak: Penyakit yang disebabkan oleh infeksi protozoa dari genus Eimeria pada usus halus kelinci, disebut kok- sidiosis usus (Intestinal Coccidiosis). Salah satu jenis coccidia penyebabnya adalah E. magna. E. magna ini adalah parasit intraseluler, yang menyerang usus halus kelinci terutama bagian jejunum dan ileum. Dalam siklus hidupnya E. magna mengalami tiga tahap perkembangan, yaitu: 1. Skizogoni. Pada tahap ini terjadi pembentukan skizon, ukurannya berkisar antara 10-20 น. 2. Gametogoni. Pada tahap ini terjadi perkembangan seksual, terjadi lima hari setelah infeksi. 3. Sporogoni. Pada tahap ini terjadi pembentukan spora, bentuk ini dapat menginfeksi kelinci lainnya. Ookista yang bersporulasi dapat menginfeksi kelinci dalam suatu peternakan. Ookista ini berbentuk oval kadang kadang elips, panjangnya 28-42 u dan lebarnya 20-26 u. Apabila kelinci terinfeksi oleh ookista ini, dapat menurunkan berat badan terus menerus dan akhirnya menimbulkan kematian. Kelinci yang berumur muda lebih sering terserang penyakit ini dari pada kelinci dewasa, sehingga sering menyebabkan kerugian pada peternak. Gejala klinis yang terlihat tergantung dari banyaknya jumlah ookista yang termakan oleh kelinci. Kelinci muda sering terinfeksi oleh sejumlah besar ookista yang dapat menyebabkan kematian mendadak tanpa memperlihatkan gejala klinis terlebih dahulu. Pada infeksi akut terlihat gejala-gejala penurunan berat badan, dehidrasi, banyak minum, diare yang hebat dan sering menimbulkan kematian. ...
