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: Etno-ornitologi Burung Kancilan Flores (Pachycephala nudigula nudigula Hartert 1897) pada Masyarakat Lio di Taman Nasional Kelimutu
Abstrak: Bare-throathed whistler is one of several wild birds in Kelimutu National Park (TNKL) that is believed to have correlation with Lio Community‟s belief. The estimation of Bare-throated whistler‟s population in Kelimutu National Park was about 186.41-1668.07 individual by the density about 0.0389-0.3481 ind/ha with the sex ratio 6.2:1 that spreaded on area with height of 1100 – 1600 masl. The characteristic of Bare-throated whistler‟s habitat is a natural forest with various canopy level, high plant species diversity and high density. The habitat characteristics related to the availability of food in the form of insects, cover, safety and a nesting site. Generally the most of Lio community knew the existence of Bare-throated whistler directly or from their parents‟ stories. The perceptions of Lio Community to the Bare-throated whistler‟s existence is generally support the conservation efforts. The perceptions construct the Lio Community‟s atitude that tend to be conservative to the existence of Bare-throated whistler. The attitude shown by their behavior that not cathing the Bare-throated whistler from the TNKL‟s area or the outside. The attitude have an important role to the existence of Bare-throated whistler in Kelimutu National Park‟s area.
