Judul: Pengendalian Kualitas High Carbon dan Micro Alloy Slab Steel Plant PT ABC
Abstrak: Slab Steel Plant (SSP) is one of the production unit in PT. ABC. The quality control in SSP factory was done in two group of produced slab steel that was high carbon and micro alloy. The quality of slab steel can be influenced by the chemical composition inside it. The chemical composition testing process is the process control by accomplishing the standard value that has been determined before. The process slot in producing high carbon and micro alloy slab steel in SSP factory I consist of two unit of CCM (Continuous Casting Machine) which distinguished by the width of slab steel with determined format. Based on the result of median vector test in machine difference, it is known that on both of CCM unit (machine) there is no difference in slab steel production process. T2-Hotelling control chart shows that there are still some monitoring that are beyond the pale. The MCpm index obtained was 0.089 and 0.131 each for internal grade high carbon and micro alloy. These indexes shows that high carbon and micro alloy slab steel production process have low process capability cause it produce less than 1 MCpm index value.

Abstrak: Process control is used to guarantee a product/service that was produced to meet certain specification and has high uniformity over time. Process control generally uses quality control charts that is used to detect the causes of high variability a product. Quality control charts that was used in this study was Generalized Variance control chart and Individual Hotelling T2 control chart. The Individual Hotelling T2 control chart was done after the Generalized Variance control chart was under control. Based on the results of the Generalized Variance (GV) control chart and the Hotelling T2 control chart using a confidence level of 99.73%, the process of high carbon steel was under control after observations that were outside the control limits were removed, which means variance and average of the process was under control. However, the identification of the previously uncontrolled observations was done first. One way to determine the variables (elements) that affected the out of control observation was to calculate the decomposition value of out of control observations. Based on these values, it indicated that the variables mainly causes out of control observation were Cu, Ni, S, and P.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
