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.

Judul: Analisis Statistika Pada Pengujian Kualitas Air Boiler Water Treatment Plant (WTP) Pabrik Hot Strip Mill (HSM)
Abstrak: PT XYZ is the largest steel producing company in Indonesia. In the steel making process, many raw materials are required, one of them is water (H2O). The water used in the steel-making process consists of a variety of functions, for example is a boiler water that consists of the main compound, that is Phosphate (PO4 2-), Silica (SiO2), and Hydrazine (N2H4). The presence of these compounds have a very important role in boiler water, for example as a deterrent to corrosion in boiler water pipe, so that needs to be done to control the chemical content of that compounds. Hot Strip Mill (HSM) factory is one of the plants in PT XYZ that produces steel sheet form. Water Treatment Plant (WTP) HSM is place in the factory HSM that used in the water treatment process of steel making in that factory. This study aims to look at the quality of the boiler water that used by the WTP HSM based content 3 main compound. The data used are primary data that is daily sampling from January 2011 to November 2011 with a total of 169 observations. T2 Hotelling control chart shows that there are some observations that are outside the limits. MCpm index 0.02 show that variations in process 50 times greater than the manufacturer's specifications, that meaning the process of measuring the content of chemical compounds is a lot of results that do not comply with the specifications

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.
