Analisis Pengendalian Kualitas Statistika Pada Proses Produksi Pipa Electric Resistance Welded (ERW) Di PT. X

Pengendalian kualitas dalam industri manufaktur sangat diperlukan agar produk yang dihasilkan sesuai dengan standar yang telah ditetapkan dan mampu bersaing. PT. X yang memproduksi berbagai jenis pipa baja, salah satunya adalah pipa Electric Resistance Welded (ERW). Namun dalam prosesnya, bagian Quality Control belum menerapkan peta kendali statistika untuk pemecahan masalah melalui Statistical Process Control (SPC). Pengendalian kualitas yang dilakukan melibatkan tiga karakteristik kualitas pipa ERW yaitu diameter, panjang, dan berat pipa ERW. Pengendalian terhadap mean proses menggunakan Peta Kendali T2Hotelling, sedangkan untuk pengendalian variabilitasnya menggunakan Peta Kendali Generalized Variance. Penelitian ini membagi data menjadi dua tahap. Berdasarkan proses produksi pipa ERW dengan menggunakan peta kendali peta kendali T2Hotelling dan peta kendali Generalized Variance terdapat pengamatan yang out of control. Faktor Penyebabnya utama proses tidak terkendali antara lain faktor utama yaitu manusia karena kesalahan dalam pengukuran. Hasil indeks kapabilitas proses pipa ERW menunjukkan kapabilitas proses dari karakteristik kualitas produksi pipa ERW secara multivariat sudah kapabel dan variasi proses lebih kecil toleransi dari batas spesifikasi yang ditentukan. Nilai indeks kapabilitas Cpm tahap II lebih kecil daripada indeks kapabilitas tahap

Dampak Penambangan Gambut Terhadap Biodiversitas Ikan Di Kabupaten Bengkalis, Riau*[study on the Peat Mining Impact on Fish Diversity in Bengkalis,Riau]

A study on peat mining impact on fish diversity was conducted at Perawang, Bengkalis Regency,Province of Riau between 1996 and 1997.The purpose of study is to discover the diversity and potential of fishes in relation with water quality due to peat mining activities.The results recorded 17 species belonging to 14 genus and 10 families in mining areas, while in the protected areas (with 3 Watersheds) recorded 4 species in Bukit Batu, 21 species in Siak Kecil and 17 species in Kampar.Cyprinidae is dominant family in mining areas, while Belontiidae in protected areas.The water quality ranges are DO between 0.49 and 4.60 ppm, CO2 between 2.31 and 26.36 ppm, pH between 3.80 and 4.80 and turbidity 1.40 and 4.20. The potential offish found are mainly consumption and ornamental fish

Mitigasi Bencana Aliran Debris Sungai Belanting secara Non Struktural Desa Belanting Kecamatan Sambelia Kabupaten Lombok Timur – Nusa Tenggara Barat

Belanting village, situated in the foot of Rinjani mountain range and crossed over by Belanting River, is a fast-growing village. Almost all of its inhabitants are migrants who came there on their own support. On January 21, 2006, a disaster strucked: debris flow came, taking people's lives and creating havoc to local infrastructures. One of the difficulties in the area is that the lack of non-structural disaster mitigation. At this rate, a study is required concerning the awareness of local inhabitants of the threat posed by debris flow hazard. The objective of the study is to identify the level of local people's understanding on debris flow disaster, to be functioned as determining basis for disaster management pattern by non-structural mitigation. Data were collected from questionnaires and interviews for 80 respondents. The resulting questionnaire data were then analyzed using SPSS (Statistic Pocket for Social Science). Result of the analysis indicates that 52.5 per cent of respondents have not understood the threat of disaster. In the meantime, the interviews indicate that religious leaders (Tuan Guru) hold high social status. Based on the result of the analysis and interviews, there is a need for a strategy in non-structural mitigation program and, as far as the study is concerned, socialization during public religious learning regarded as more effective and efficient efforts

Kandungan Bakteri Total Coli Dan Escherechia Coli / Fecal Coli Air Minum Dari Depot Air Minum Isi Ulang Di Jakarta, Tangerang, Dan Bekasi

A study on drinking water quality produced by drinking water refill depots (AMIU) was done in Jakarta, Tangerang and Bekasi. Analysis unit of the study was drinking water refill depots with the sample number of 38 depots. For every selected depot, laboratory analysis were done for natural water (clean water) and drinking water produced by the depots. The total number of sample were 76 water samples. One of the parameters analyzed was microbiological contents, namey total coli bacterial count and Escherechia coli / fecal coli. For collecting information about the sources and storage of natural waters, drinking water treatment processes, treatment equipment, and so on, the depots operators and drinking water refill association personnel were interviewed as well as the water treatment equipment distributors. Based on the interview, it can be stated that the main principles of the water treatment processes from natural water to become drinking water in the AMIU depots were only filtration and disinfections processes. Natural water sources mostly was mountain spring water (89.5%), originated from Bogor (60.5%). and Sukabumi (26.3%). According to the results of laboratory analysis, it can be stated that the percentages of the natural water samples which were not complying with the standards of total coli bacterial count was 31.6% and that of fecal coli was 28.9%. Whereas for drinking water produced by the depots, the percentages of water samples which were not complying with the total coli bacterial count and fecal coli standards were 28.9% and 18.4% respectively. Additionally, the drinking water treatment processes were not sufficient for natural water with the high contents (around 1.600 MPN/100 ml) of total coli and fecal coli bacterial
