Judul: Pengendalian Proses Secara Statistika Pada Pengujian Komposisi Kimia Dalam Baja Di PT Krakatau Steel (Persero) Tbk,Cilegon
Abstrak: PT Krakatau Steel (Persero) Tbk memiliki Dinas Laboratorium Kimia Bahan Baku/ Bahan Pembantu Divisi Pengendalian Kualitas yang bertugas untuk menguji komposisi kimia dalam baja dengan menggunakaan alat Spectrolab M-7. Komposisi kimia yang terkandung dalam baja sangat berpengaruh terhadap kualitas produk yang dihasilkan. Proses pengujian komposisi kimia di perusahaan saat ini merupakan pengendalian proses dengan melakukan pemenuhan nilai standar yang telah ditentukan, dan menunjukan terdapat indikasi adanya ketidakstabilan proses. Suatu proses dianggap stabil adalah proses yang menghasilkan produk dengan keragaman yang hanya disebabkan oleh keragaman alami, sedangkan untuk keragaman tidak alami harus dihindarkan. Oleh karena itu, penelitian ini bertujuan untuk melakukan pengendalian proses secara statistika dengan menerapkan bagan kendali mutu individu dan moving range. Penerapan dari bagan kendali mutu moving range menunjukan bahwa keragaman yang terjadi pada proses pengujian komposisi kimia merupakan keragaman tidak alami, sehingga proses tersebut perlu upaya untuk mengendalikan agar tetap berada dalam keadaan terkendali secara statistika. Proses pengujian komposisi kimia dalam baja memerlukan perhatian khusus pada unsur terpenting dalam baja yaitu unsur Karbon (C), Sulfur (S), dan Silikon (Si). Perhatian khusus ini dikarenakan unsur kimia C, S, dan Si memiliki nilai rendah pada persentase banyaknya pengamatan terkendali. Peneliti memberikan informasi tentang upaya pengendalian proses agar menjadi lebih baik lagi. Informasi tersebut mengenai evaluasi pada pengamatan tidak terkendali. Evaluasi ini dilakukan dengan eksplorasi dot plot pada tanggal pengamatan yang tidak terkendali. Hasil dari eksplorasi tersebut menunjukan bahwa pelaksanaan dalam mengendalikan proses pengujian komposisi kimia lebih dioptimalkan lagi pada waktu pertengahan bulan, sehingga dapat meminimumkan keragaman tidak alami di PT Krakatau Steel (Persero) Tbk, Cilegon.

Judul: Evaluasi Kepuasan Pengguna Jasa Laboratorium Kimia PT Krakatau Steel (Persero) Tbk Tahun 2012-2013
Abstrak: One of the services contained in PT Krakatau Steel (Persero) Tbk is the chemical composition analysis services in the chemistry lab. Management system that will create a well-managed laboratory performance is optimal. Manage standard chemistry laboratory is SNI ISO/IEC 17025. Discussed in this standard laboratory management such as through customer feedback. Laboratory customers selected through stratified random sampling with customer categories as strata, like suppliers, derived from plant and internal processes are not routine. In the research lab result that the customer will be satisfied, including services rendered for customer satisfaction index (CSI) is greater than 70% with the overall characteristics of the respondents subscription in the laboratory was 11.6 years. Overall the indicators included in the priority importance performance analysis (IPA) and has a value kesenjangan beyond the maximum tolerance through kesenjangan analysis approach is the completeness of laboratory equipment (F) and speed of service (K).

Judul: Peran burung air liar dalam penyebaran virus avian influenza subtipe H5N1 di Cagar Alam Pulau Dua
Abstrak: Waterfowls such as ducks, muscovy, and swans are natural reservoir of influenza virus subtype H5N1. In natural reservoir, the AI virus is Low Pathogenic Avian Influenza (LPAI). Instead of domestic waterfowls, wild waterbird species could also have a role in spreading AI subtype H5N1 virus. So far LPAI have been isolated from 105 species of wild birds, most of them were from Anseriformes and Charadiiformes order. Presumption that wild birds and migratory birds have a role in spreading AI virus, has not been proven until now because the intensive research has not been done. The mortality rate of wild waterbirds that reported in several countries, had not clearly explained the cause of death. The objectives of this research were (1) to estimate the seroprevalence of AI virus subtype H5N1 from residence wild waterbirds, in Pulau Dua Nature Reverse; (2) to identify the Mx gene as resistant anti viral gene from AI virus in wild waterbirds; (3) to identify the presence of AI virus subtype H5N1 on residence waterbirds in Pulau Dua Nature Reverse, also to observe the potential of wild waterbirds as reservoir for spreading AI virus subtype H5N1 The serological test to detect the presence of antibody antiviral AI virus subtype H5N1 was used to determine the exposure of AI virus subtype H5N1 among wild waterbirds in CAPD. Since antibody is the substance that appear in individual exposed when they are exposed by the strange antigen. The serosurveillans from wild waterbirds in CPAD had been done in 2008, 2010 and 2011. Serological test by Haemagglutinin-inhibition (HI) showed that six from nine species of residence wild waterbirds in CPAD produced antibody AI virus H5N1. It is explain that that those species were exposed by AI virus subtype H5N1 with low antibody titer. The low antibody titer can be caused by several factors such as AI virus exposure occurring indirectly, there was a small number of virus that exposure to wild waterbirds, the exposure time was very short, and the virus was low pathogenic. Indirect transmission occurred through the water as the source of drinking water for wild and domestic waterbirds, through saliva and nasal secretions and feces. Water as a media for transmission virus where there were interactions between wild waterbirds, waterfowls and domestic birds. Mx protein as part of dynamin super family (GTP ase) is a part of the innate immune system. Mx proteins were known to have the ability to inhibit the replication of various viruses. Mx protein coded by Mx genes that specifically anti-viral influenza in several animals. Mx gene was the one of the several genes that regulated myxovirus resistance. DNA of eight wild waterbirds species and three domestic birds (chicken, duck and Muscovy) around CAPD were examined by PCR using NE-F2 and NER2/ R primer obtaining PCR product with a length of 100 bp band. It indicated that most birds could have 100 bp band. These results explained that the Mx gene in residence wild waterbirds from CAPD could be the same as in the chicken, muscovy and duck. The results of PCR-RFLP in wild waterbirds and
