Judul: Evaluating Quality Control Measures for Ensuring High pH Bottled Water Compliance with Product Quality Standards: A Case Study of PT. XYZ
Abstrak: ALDRICHSYAH YOGA PRATAMA. Evaluating Quality Control Measures for Ensuring High pH Bottled Water Compliance with Product Quality Standards: A Case Study of PT. XYZ. Dibimbing oleh Dr.-Ing. Dase Hunaefi STP, MFoodSt. Pengendalian kualitas adalah mengukur keadaan sebuah produk, membandingkannya dengan standar dan spesifikasi produk, serta mengambil tindakan perbaikan jika terdapat penyimpangan. Suatu produk dikatakan memiliki kualitas baik jika sesuai dengan standar yang telah ditentukan atau ditetapkan. Ruang lingkup standar mutu meliputi bahan baku, proses produksi, dan produk jadi. Analisis pengendalian mutu air minum kemasan dengan pH tinggi di PT XYZ diperlukan untuk menentukan tahapan pengendalian mutu secara keseluruhan baik dari penerimaan bahan baku, proses produksi, sampai proses pengemasan produk akhir. Kemudian pada kondisi yang tidak sesuai dengan parameter yang telah ditetapkan perusahaan, dilakukan analisis untuk mengetahui akar permasalahan yang terjadi agar permasalahan tersebut dapat segera diperbaiki. Analisis kendali mutu menggunakan pendekatan statistik, selain itu diagram pareto, diagram tulang ikan, dan peta kendali digunakan dalam pembuatan skripsi ini. Pada air minum murni 600 ml, jenis ketidaksesuaian yang paling umum terjadi adalah pada botol, label, tutup botol, dan tutup segel. Untuk mengetahui ketidaksesuaian yang terjadi pada proses terkendali atau tidak, maka jumlah ketidaksesuaian selama 13 minggu dianalisis menggunakan peta kendali, hasil analisis menunjukkan proses produksi tidak terkedali.

Judul: Six Sigma Implementation in Quality Control System at PT. Air Gunung Salak
Abstrak: Permintaan Air minum dalam kemasan setiap tahun semakin meningkat, sehingga persaingan yang terjadi membawa setiap pelaku industri untuk meningkatkan nilai dari produk yang dihasilkan dengan cara melakukan pengendalian kualitas terhadap tingkat kerusakan produk (product defect) sampai pada tingkat kerusakan nol (zero defect). Tujuan penelitian ini adalah untuk mengetahui permasalahan utama dan faktor yang mempengaruhi dalam pengendalian mutu di PT. Air Gunung Salak. Pengolahan data dilakukan dengan perhitungan six sigma didapat Defect per Unit sebesar 0,028996661. Sedangkan Defect per Million Opportunity sebesar 5.799,3, apabila di konversi ke dalam tabel sigma didapat nilai sigma sebesar 4,02. Critical To Quality untuk product reject yaitu Reject air, Kotor Dalam, Reject Galon, Reject Cup dan Reject seal dan permasalahan utama adalah Reject Air dengan rekomendasi rancangan perbaikan yang disarankan dengan memperketat pengawasan pada proses pendistribusian ke pelanggan dengan melakukan pengantaran pada pagi atau malam hari., The demand for bottled drinking water is increasing every year, so that the competition that occurs brings every industry player to increase the value of the products produced by controlling the quality of the level of product defects to zero defects. The purpose of this study was to determine the main problems and factors that influence quality control at PT. Air Gunung Salak. Data processing is done by calculating the six sigma obtained Defect per Unit of 0,028996661. Meanwhile, Defect per Million Opportunity is 5.799,3, when converted into the sigma table, the sigma value is 4,02. Critical To Quality for reject products, namely water rejects, dirty gallon water, gallon rejects, cup rejects and seal rejects and the main problem is water rejects with recommendations for improvement designs by tightening supervision on the distribution process to customers by delivering in the morning or evening.

Judul: Distribution and Diversity of Ectoparasite Mites on Geckos in Indonesia
Abstrak: Data on the diversity and dispersal of parasitic mites on house geckos in Indonesia are very scarce. In this work, the distribution and diversity of mites living on three species of house geckos, namely Cosymbotus platyurus, Hemidactylus frenatus, and H. garnotii collected throughout Indonesia, has been elaborated. Geckos and mites were captured and immediately preserved in 70% ethanol. Whole mount of the mites was prepared by clearing in lactophenol followed by mounting on polyvinyl lactophenol solutions. The SEM preparation was conducted to examine the detail morphological characters of the mites. The results showed that among 448 individuals of geckos, 221 geckos were infected by Geckobia mites. Prevalences of C. platyurus, H. frenatus, and H. garnotii infested by mites were 14.8%, 50.69%, and 79.6%, respectively. Three different spesies of Geckobia (G1, G2, and G3) could be differentiated; and based on similarities of their morphological characters to ones described in published literatures, Geckobia G2 is Geckobia glebosum and Geckobia G3 is Geckobia bataviensis while G1 could not be identified to the species level. The highest mean intensity of Geckobia G1 infestation was found on H. garnotii (I=7.0), G. glebosum infestation on H. frenatus (I=3.5), and G. bataviensis infestation on H. garnotii (I=11.8). In general, C. platyurus was infested by the least number of mites. Geckobia G1 were found living on the skin folds on the claws, G. glebosum were found mainly on the body and thigh, and G. bataviensis were found on almost all parts of the host’s body. Geckobia mites are distributed randomly throughout Indonesian Archipelago, following the pattern of distribution of their hosts. So it is concluded that Geckobia G1, G. glebosum, and G. bataviensis are sympatric.
