Judul: Pendugaan komponen periodik fungsi intensitas berbentuk fungsi periodik kali tren kuadratik suatu proses Poisson non-homogen
Abstrak: This manuscript is concerned with estimation of periodic component of the intensity function of form periodic function multiplied by quadratic trend of a non-homogeneous Poisson process. It is considered the worst case, where there is only a single realization of a Poisson process with intensity function of form periodic component multiplied by a quadratic trend were observed in the interval [0,n]. It is assumed that the period of the periodic component is known. An estimator of the periodic component of the intensity function has been formulated and its Mean Square Error (MSE) has been proved converges to zero as n   . In addition, asymptotic approximations to the bias, variance, and the Mean Square Error (MSE) of the estimator have been formulated. An asymptotically optimal bandwidth for this estimator is also determined.

Judul: Asymptotic Distribution of an Estimator for Periodic Component of the Intensity Function Obtained as the product of a Periodic Function with the Quadratic trend of a Non Homogenous Poisson Process
Abstrak: In this thesis, estimation of periodic component of the intensity function obtained as the product of a periodic function with the quadratic trend of a non homogeneous Poisson process by using general kernel is discussed. It is considered the worst case where there is only available a single realization of the Poisson process having intensity of form a periodic function multiplied by the quadratic trend, observed in interval [0,n]. It is assumed that the period of the periodic component is known. It has been constructed estimator of periodic component of the intensity function of form periodic function multiplied by the quadratic trend of a non homogenous Poisson Process. Statistical properties of this estimator are also formulated. Finally, asymptotic normality of the estimator is also given.

Judul: Diare pada anak sapi akibat infeksi virus corona bovine
Abstrak: Melihat tingginya mortalitas anak sapi yang berumur kurang dari tiga bulan di Indonesia mencapai 20 %, perlu kiranya mempelajari sebab-sebab kematiannya. Diare sering mengakibatkan kematian pada anak sapi yang baru lahir, salah satu sebab diare adalah infeksi virus Corona Bovine. Kasus diare oleh virus Corona Bovine (VCB) belum pernah dilaporkan di Indonesia, meskipun demikian kita harus was- pada terhadap sapi-sapi import. Virus Corona Bovine (VCB) mempunyai 6 karakteristik yaitu 1. Struktur permukaannya mempunyai paku-paku tegak lurus; 2. Ukuran besar 120 nm; 3. Berat jenis 1,18 gr/ml; 4. Replikasi dalam kantung sitoplasma; 5. Mempunyai inti RNA; 6. Mempunyai amplop yang mengandung lemak. VCB banyak menyerang anak sapi umur 5-21 hari dan ditularkan melalui feses, oleh hewan sakit atau hewan carier juga alat-alat yang terkontaminasi feses. Masa inkubasinya 19-24 jam dengan morbiditas dan mortalitas masing-masing mencapai 100% dan 30%, sehingga kerugian ekonomi yang disebabkan oleh infeksi VCB cukup berarti bagi suatu usaha peternakan sapi. Target organ VCB adalah villi usus halus dan usus besar, yang mengakibatkan atropy villi, malabsorpsi dan dehidratasi. ...
