Judul: Pengetahuan, Sikap, dan Praktik Personel Instalasi Karantina Hewan Day Old Chick (IKH DOC) BBKP Soekarno Hatta Mengenai Biosekuriti
Abstrak: This study was conducted to analyze level of knowledge, attitudes and practices of installation personnels related to biosecurity, correlations among knowledge, attitudes and practices of installation personnels related with biosecurity in animal quarantine installations and level of biosecurity measures in quarantine installation. Measuring the level of knowledge, attitudes, and practices of respondents conducted with interviews using questionnaires and observation. Data analysis to determine associations between these variables using Spearman and Pearson correlation test. This research revealed that knowledge and attitude of manager significantly correlated with low correlation level, knowledge and practice of veterinarian significantly correlated with medium correlation level and worker practice and attitude significantly correlated with medium correlation level. Biosecurity level in quarantine installation determined by manager’s knowledge and practice, veterinarian’s practice and worker’s practice.

Abstrak: This study was conducted to analyze knowledges, attitudes and practices of installation personnels related to animal welfare and biosecurity to correlate knowledge, attitudes and practices of installation personnels to measure the level of animal welfare and biosecurity in animal quarantine installations. Data were collected from animal quarantine premises for exported primate (Macaca fasicularis). The level of knowledge, attitudes and practices of respondences measure by interviews and observation using the questionnaires and checklist. Data analyzed to determine associations between these variables using chi square and Gamma test. This research revealed that veterinarian knowledge correlated to their attitude with the level of correlation 0.694, and the care taker knowledge correlated to their attitude with the level of correlation 0.575. This study also noticed that the characteristics of respondents showed no correlation between animal welfare and biosecurity implementation, while the knowledge and attitude of veterinarians showed a strong correlation between animal welfare and biosecurity implementation with medium correlation level (r = 0.694). On the other hand the knowledge and attitude of care takers showed a strong correlation between the animal welfare and biosecurity with medium correlation level (r = 0.575). In conclusion most of the knowledge, attitude and practice of the veterinarians were verygood and knowledge, attitude and practice of the managers and care takers were good.

Judul: Monotonicity Properties of Trapezoid Sum Sequence on Class of Nonconvex and Nonconcave Function
Abstrak: Bernhard Riemann mendefinisikan integral tentu sebagai luas daerah di bawah kurva dari suatu fungsi real taknegatif pada sebuah interval yang tertutup dan terbatas. Beberapa alternatif yang dapat digunakan untuk menghampiri luas tersebut adalah Darboux sums melalui penjumlahan beberapa luas persegi panjang dan trapezoid sum melalui penjumlahan luas trapesium. Trapezoid sum lebih baik dalam menghampiri nilai integral untuk fungsi-fungsi yang well-behaved daripada Darboux sums. Untuk fungsi f yang bernilai real dan kontinu pada interval [a,b], f terintegral Riemann jika dan hanya jika f terintegral Darboux. Pada tesis ini ditunjukkan bahwa f terintegral Riemann jika dan hanya jika f terintegral secara trapesium. Misalkan f adalah suatu fungsi bernilai real yang kontinu pada interval [a,b]. Untuk setiap partisi P_n yang membagi [a,b] menjadi n subinterval dengan jarak yang sama, dibentuk trapezoid sum T_n (f) yang merupakan jumlah luas n trapesium sebagai pendekatan dari nilai integral f pada [a,b]. Jika f adalah fungsi konveks maka barisan trapezoid sum {T_n (f)} bersifat monoton turun dan akan bersifat monoton naik jika f fungsi konkaf. Fokus tesis ini adalah sifat kemonotonan barisan {T_n (f)} untuk fungsi f yang nonkonkaf dan fungsi f yang nonkonveks. Pada tesis ini dibuktikan sifat monoton turun dari {T_n (f)} secara generik tidak terjadi pada kelas fungsi nonkonkaf f, serta secara generik, barisan itu juga tidak monoton naik pada kelas fungsi nonkonveks. Meskipun demikian, sifat generik mengakibatkan bahwa untuk sebarang fungsi f baik di kelas fungsi nonkonkaf maupun nonkonveks, terdapat fungsi g yang menghampiri f sedemikian sehingga ekor barisan {T_n (g)} bersifat monoton. Ditunjukkan pula bahwa himpunan fungsi naik nonkonkaf dengan {T_n (f)} yang tidak monoton turun dense terhadap kelas fungsi naik nonkonkaf f. Hal tersebut juga ditunjukkan untuk himpunan fungsi turun nonkonkaf terhadap kelas fungsi turun nonkonkaf. Lalu, dibuktikan bahwa himpunan fungsi naik nonkonveks dan himpunan fungsi turun nonkonveks dengan {T_n (f)} yang tidak monoton naik, berturut-turut dense terhadap kelas fungsi naik nonkonveks dan turun nonkonveks. Himpunan-himpunan yang dense tersebut mengartikan bahwa setiap fungsi f pada kelas-kelas tersebut, dapat dihampiri oleh suatu fungsi g yang bersesuaian dengan kelas-kelas tersebut sedemikiam sehingga barisan {T_n (g)} tidak monoton., Bernhard Riemann defined definite integral as an area under the curve of a real nonnegative function on a closed bounded interval. The alternatives that can be used to estimate the area are Darboux sum which is sum of rectangular areas and trapezoid sum which is sum of trapezium areas. Trapezoid sum is better than Darboux sum as approximations toward the integral of well-behaved functions. Let f be a real valued continuous function on interval [a,b], f is Riemann integrable if and only if it is Darboux integrable. In this master’s thesis, it showed that f is Riemann integrable if and only if it is trapezium integrable. Let f be a real valued continuous function on interval [a,b]. For each partition P_n that divides the interval [a,b] into n equal length subintervals, defined trapezoid sum T_n (f) which is the total of n trapezium areas as an approach of integral value f on [a,b]. If f is a convex function then the trapezoid sum sequence {T_n (f)} is decreasing
