Judul: Analysis of the Dairy Cattle Internal Diseases Cases Occurrence at KPSBU Lembang During 2015-2019
Abstrak: Studi ini bertujuan mengetahui tingkat kejadian kasus penyakit dalam pada sapi perah di KPSBU Lembang tahun 2015-2019 dan dugaan hubungannya dengan faktor cuaca. Data kejadian penyakit diperoleh dari Laporan Praktik Lapang Pelayanan Kesehatan Klinik Sapi Perah oleh mahasiswa PPDH IPB di KPSBU Lembang tahun 2015-2019. Data kejadian penyakit yang didapatkan kemudian dibandingkan dengan dinamika cuaca di daerah Lembang. Kejadian penyakit dikelompokkan berdasarkan trimester kejadian waktu yaitu trimester pertama (Januari – Maret), trimester kedua (April – Juni), trimester ketiga (Juli – September), hingga trimester keempat (Oktober – Desember). Didapatkan sepuluh besar penyakit yang paling banyak terjadi. Penyakit yang diduga berhubungan dengan cuaca terutama musim hujan adalah artritis, enteritis, dan timpani. Penyakit yang diduga tidak berhubungan dengan cuaca adalah mastitis, parturient paresis/milk fever, pododermatitis, dan abses. Penyakit yang diduga berhubungan dengan cuaca kering/musim kemarau adalah retensi plasenta., The objectives of this study were to analyses the internal disease cases incidences rate in KPSBU Lembang since 2015 until 2019 and its suspected correlation to the weather. Data were collected from Laporan Praktik Lapang Pelayanan Kesehatan Klinik Sapi Perah written by PPDH FKH IPB students at KPSBU Lembang since 2015 until 2019. The collected data were compared to the weather dynamics at Lembang region. The diseases occurrence was classified based on monthly trimester, the first trimester (January – March), second trimester (April – June), third trimester (July – September), and fourth trimester (October – December). Based on the data, there were ten most frequent diseases that occurred at KPSBU Lembang. Diseases which were suspected to correlate with the rainy weather were arthritis, enteritis, and tympany. The disease which was suspected to correlate with the dry weather was placenta retention. Diseases that were not suspected to correlate with the weather were mastitis, parturient paresis/milk fever, pododermatitis, and abscess.

Judul: Analysis of the Incidence Rate of Surgical Disease in Dairy Cows at the KPSBU Lembang, West Java 2015-2019
Abstrak: Studi ini bertujuan mengidentifikasi tingkat kejadian kasus penyakit bedah yang sering terjadi pada sapi perah dan dugaan hubungannya dengan cuaca serta faktor lain di Koperasi Peternak Sapi Bandung Utara (KPSBU) Lembang, Jawa Barat pada periode tahun 2014-2019. Data kejadian penyakit diperoleh dari buku Laporan Praktik Lapang Pelayanan Kesehatan Klinik Sapi Perah oleh mahasiswa PPDH FKH IPB di KPSBU Lembang periode tahun 2015-2019. Kejadian penyakit dikelompokkan berdasarkan trimester waktu 12 bulan yaitu trimester pertama (bulan Januari-Maret), trimester kedua (bulan April-Juni), trimester ketiga (bulan Juli-September), dan trimester keempat (bulan Oktober-Desember). Data kejadian penyakit dibandingkan dengan dinamika cuaca di daerah KPSBU Lembang. Lima besar kasus penyakit bedah yang terjadi di KPSBU Lembang adalah arthritis, pododermatitis, timpani, Dislokasi Abomasum (DA), dan abses. Penyakit yang diduga berhubungan dengan cuaca yaitu arthritis, pododermatitis, timpani, dan dislokasi abomasum. Penyakit yang diduga tidak berhubungan dengan cuaca yaitu abses., This study aims to identify the incidence of surgical disease cases that often occur in dairy cows and its suspected correlation with weather and other factors in the Koperasi Peternak Sapi Bandung Utara (KPSBU) Lembang, Jawa Barat year 2014-2019. Data was collected from Laporan Praktik Lapang Pelayanan Kesehatan Klinik Sapi Perah written by PPDH IPB students at KPSBU Lembang year 2015-2019. Diseases occurence are divided based on trimester which is the first trimester (January-March), second trimester (April-June), third trimester (July-September), and fourth trimester (October-December). Disease incidence data is compared with weather dynamics at Lembang region. The top five cases of surgical disease that occurred at KPSBU Lembang were arthritis, pododermatitis, tympani, Dysplasia Abomasum (DA), dan abscess. Diseases that are suspected to have a direct correlation to the weather are arthritis, pododermatitis, tympani, Dysplasia Abomasum (DA). Diseases that are suspected to not have a direct correlation to the weather are abcess.

Judul: Sintesis Nanokomposit Kaolin/TiO2 Teremban Fe2O3 untuk Adsorpsi-Fotodegradasi Biru Metilena
Abstrak: Kaolin is a type of clay mineral that has adsorption capacity. The experiment shows that the adsorption capacity of kaolin was 20.6 mg/g. This value is lower than zeolite adsorption capacity that in general has value above 100 mg/g. Mixing kaolin with other materials to form nanocomposite, may improve its adsorption properties. Nanocomposites that had been synthesized were kaolin/TiO2 nanocomposites with the addition of Fe2O3 using 2 synthetic methods, namely using ball milling and paste methods. The nanocomposite synthesized using ball milling method had higher adsorption capacity value, i.e. 23.6 mg/g. The nanocomposite of kaolin/ TiO2 was able to adsorb and degrade waste dyes in ultraviolet range. Furthermore, addition of Fe2O3 to the kaolin/TiO2 nanocomposite improved the performance of the nanocomposite by reacting under the visible rays. Therefore, the performance of nanocomposite of kaolin/TiO2 added with Fe2O3 was is more effective since visible ray is the major part of the sun light.
