Judul: Sistem Intelijen Penilaian dan Prediksi Kualitas Susu Pasteurisasi (Studi Kasus pada PT . Industri Susu Alam Murni Bandung)
Abstrak: The aim of this research is developing an intelligent system for assessment and prediction of pasteurized milk quality. The system is implemented by integrated expert systems and Artificial Neural Network (ANN). This system is designed and developed by Matlab 6.5 and called SINKUAL-SP. The logical strategy model used is “Forward Chaining” and the tracing method used is “Best First Search” method. The method of Certainty Factor (CF) is used for handling uncertainty. Model Based Management system consist of five model : quality of fresh milk model, quality of process model, quality packaging and storage model, statistical process control model and prediction model by neural network. Multilayer system is used for the neural network architecture with one input layer, one hidden layer dan one output layer. The activation function is Sigmoid Bipolar activation function which gives the best performance network with learning rate 0.005 and momentum 0.9 together with RMSE, MSE and SSE as criterion error. The validation for neural network indicates the conformity between output of neural network and output of goal with value of RMSE 0.009959, MSE 0.00999 and SSE 0.009950. Decision for acceptance fresh milk and pasteurized of milk is implemented by acceptance grade which gives control quality process is easier than previously system. Based on the grade acceptance, the management of industry can take decision and action allow with a significant output of grade. In the research implementation stage, the data, gained in the company of “PT. ISAM” in April 2005, brings a significant output of research regarding quality of fresh milk such as the grade B, grade A for quality of process, and grade B for quality packaging and storage. This system gives a suggestion for user to improve the quality of pasteurized milk. Based on the outputs from the systems used, highly priority strategy quality system reconstruction, with 0.236 as weighting value. The quality improvement system upon the results of research is seemed to be a way of improving the quality of milk in process of pasteurization.

Judul: Analisis Penerapan Proses Pengendalian Mutu Susu Pasteurisasi Pada Industri Pengolahan Susu : Studi Kasus Di Pt. Indomilk
Abstrak: Pertanian merupakan sektor yang penting bagi ketahanan bangsa Indonesia, bukan saja karena mampu menyerap tenaga kerja tetapi juga bisa menjadi penggerak perekonomian menuju masyarakat industri. Pertanian hendaknya tidak dilihat sebagai usaha primer saja tetapi merupakan satu kesatuan sistem dengan agrobisnis dan agroindustri. Sayangnya sektor pertanian kita masih bersifat tradisional dan seringkali kalah bersaing baik dipasar 1oka1 apalagi dipasar intemasional. Hal ini terjadi antara lain disebabkan mutu produk-produk pertanian kita masih terbi1ang rendah. Untuk itu diperlukan upaya-upaya untuk menaikan mutu produk tersebut. Beberapa teknik yang dapat digunakan untuk membantu meningkatkan mutu produk adalah dengan rumah mutu (Quality Function Deployment, QFD) dan pengendalian proses statistikal (Statistical Process Control, SPC). Pada tesis ini dilakukan analisis penerapan pengenda1ian mutu di PT Indomilk, salah satu perusahaan pengolahan susu di Indonesia. Mengingat akan diberlakukannya pasar bebas, maka teknik QFD dan SPC untuk meningkatkan mutu menjadi penting untuk dilaksanakan namun yang menj adi permasalahan adalah strategi operasional seperti apa yang perlu dilakukan agar produk tetap disukai pelanggan, bagaimana model pengendalian mutu yang sesuai pada industri pengolahan susu, sejauh mana kestabilan dan kemampuan proses yang telah dilakukan oleh perusahaan saat ini serta, strategi perbaikan apa yang paling sesuai yang harus dilakukan oleh perusahaan untuk memperbaiki mutu. Dengan melihat permasalahan diatas, maka tujuan dilaksanakannya penelitian ini adalah untuk mengetahui strategi operasional yang paling tepat agar produk tetap disukai pelanggan, menentukan model penerapan mutu yang sesuai berdasarkan teknik SPC pada industri pengolahan susu, mengetahui kemampuan proses yang sedang berjalan pada industri pengolahan susu, mengetahui strategi perbailcan yang paling sesuai dalam penerapan pengendalian mutu pada industri pengolahan susu. Ruang lingkup penelitian ini adalah pada pros('s pembuatan susu pastuerisasi di PT Indomilk dengan penentuan strategi operasi, identifikasi masalah mutu prioritas, pemantauan kestabila:n proses, penentuan kemampuan proses dan strategi perbaikan. Penelitian ini dilaksanakan di PT Indomilk, Jakarta, pada bulan Juni dan Juli 2001. Penelitian dimulai dari menetapkan strategi operasi. mengidentifikasi masalah mutu prioritas, memantau proses, menghitung indeks kapabi!itas dan merumuskan strategi perbaikan yang tepat. Metodc yang digunakan adalah dalam bentuk deskripitif kuantitatif melalui studi kasus dengan melakukan pengamatan dan wawancara. ..dst,

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.
