Abstrak: Proficiency testing was inter laboratory comparisons. The same sample could have different test results when tested in some different laboratories. To find out and improve the performance of laboratories, proficiency testing can be done. Different evaluation of test results from participant laboratories could make different interpretations of the proficiency testing, which means it can also affect the assessment of the participant laboratories. The aims of this research are 1) to design a system for proficiency testing by using several evaluation methods of test results 2) to identify the testing methods used by the participant laboratories and possible causes of outlier laboratories. The method used in this research are: method 1: one round data selection by Grubbs and the rest of the data is calculated by Robust Z-Score; method 2: data selection by Grubbs several times until no more data can be excluded and the rest data is calculated by Robust Z-score; method 3: direct calculation by Robust Z-Score; method 4: calculation by reference value. The data used are the results of proficiency testing of cocoa powder, chili sauce and vegetable oil; reference values come from German reference laboratory; interview result from the stakeholders and field observations for related testing. The results show the median from Indonesian laboratories are not too different from the reference value; distributions of data are large enough, proved by CV robust larger than CV Horwitz (except for cadmium and the amount of dissolved solid); method 2 is chosen as the best method based on the smallest CV Robust; method 2 is the most sensitive which is giving the bigger number of outlier laboratories than methods 1 and 3; the number of outlier laboratories with method 2 are less than method 4; testing laboratories using National Standard of Indonesia (SNI) obtained satisfactory results (40% -100%) by method 2, for most of the test parameters; possible causes of outlier laboratories results come from a variety factors, particularly the implementation of testing that does not comply with the testing method.

Abstrak: LDITP-IPB is a testing laboratory ISO 17025 refers to give priority to customer satisfaction. The purposes of this research are: identified characteristics of consumers, identify the process of buying decision and to analysis the level of customer satisfaction of LDITP-IPB. This study used a descriptive analysis, Importance Performance Analysis and Customer Satisfaction Index. The results showed that the service quality of LDITP-IPB obtained customer satisfaction index by 84.55 percent, which means very satisfied in the criteria. From the results of the IPA method, the service quality attributes that need to be improved LDITP-IPB are: testing should be done on time based on the agreement, the ability to provide an explanation of laboratory testing results, responsiveness in handling testing requests, courtesy and friendliness employees, than appropriate and competitive cost of testing.

Judul: Karakteristik Anatomi Skelet Kepala Buaya senyulong (Tomistoma schlegelii).
Abstrak: Buaya sepit atau senyulong (Tomistoma schlegelii) merupakan jenis buaya asli Indonesia yang berhabitat di sungai-sungai Sumatera, Kalimantan, dan juga pedalaman Sulawesi. Salah satu ciri khas buaya senyulong adalah bentuk moncong yang runcing dan sempit, namun hingga saat ini informasi mengenai struktur skelet kepala buaya senyulong sangat terbatas. Penelitian ini bertujuan untuk mempelajari karakteristik anatomi skelet kepala buaya senyulong yang dikatikan dengan fungsi dan perilakunya. Penelitian dilakukan secara eksploratif dengan melakukan pengamatan, pencatatan, dan pengambilan gambar dari skelet kepala buaya senyulong. Skelet kepala berukuran panjang 70 cm, lebar 29 cm, dan tingggi 17 cm dengan permukaan kasar pada os nasale, os frontale, os maxilla, os mandibula, os lacrimale, os jugale. Jumlah gigi pada buaya ini sebanyak 78 buah, terdiri dari 4 buah gigi premaxila, 16 buah gigi maxila, dan 19 buah gigi mandibula. Pada regio orbitalis ditemukan dua pasang fenestrae temporales yang berkembang baik. Fenestra supratemporale merupakan lubang oval yang membentang di sepanjang os parietale. Fenestra infratemporale berbentuk segitiga dan dibatasi oleh os squamosum, os postorbitale, os jugulare, dan os quadratum. Os mandibula hewan ini mempunyai symphysis mandibularis yang panjang yaitu garis yang melintang di corpus mandibulae. Secara fungsional ukuran symphysis mandibularis berkaitan dengan adaptasi hewan terhadap diet makan.
