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: Studi Tingkat Kejadian Kasus Penyakit Dalam pada Sapi Perah di Koperasi Peternakan Bandung Selatan (KPBS) Pangalengan Tahun 2014 - 2019
Abstrak: Studi ini bertujuan mengidentifikasi tingkat kejadian kasus penyakit dalam pada sapi perah di Koperasi Peternakan Bandung Selatan Pangalengan tahun 2014-2019 dan dugaan hubungannya dengan faktor cuaca. Data kejadian penyakit diperoleh dari laporan praktik lapang mahasiswa Program Profesi Dokter Hewan Institut Pertanian Bogor di KPBS tahun 2014-2019. Pengamatan terhadap suhu dan kelembapan tidak menunjukkan perubahan berarti jika dibandingkan dengan perubahan curah hujan di daerah Pangalengan. Data kejadian penyakit yang didapatkan kemudian dibandingkan dengan dinamika curah. Kejadian penyakit dan kondisi cuaca dikelompokkan berdasarkan trimester waktu dalam 12 bulan yaitu trimester pertama (Januari-Maret), trimester kedua (April-Juni), trimester ketiga (Juli-September), dan trimester keempat (Oktober-Desember) Musim Hujan di Pangalengan terjadi pada trimester pertama, kedua, dan keempat. Musim kemarau di pangalengan terjadi pada trimester ketiga. Penyakit yang diduga berkorelasi positif dengan curah hujan adalah mastitis, laminitis, dan ketosis. Penyakit yang diduga berkorelasi negatif dengan curah hujan adalah Downer Cow Syndrome. Penyakit yang diduga tidak berhubungan dengan cuaca adalah hipokalsemia, rumen asidosis, enteritis, indigesti, dan pneumonia., The objectives of this study were to analyses the internal disease case incidences rate in South Bandung Coop Farm (KPBS) Pangalengan since 2014 until 2019 and its suspected correlation to the weather. Data were collected from the field practice report of students Veterinary Profession Program (PPDH) Institut Pertanian Bogor at KPBS in 2014 - 2019. The collected data were compared to the weather dynamics at Pangalengan region. The disease occurrence and weather conditions are grouped by time trimester in 12 months, the first trimester (January - March), second trimester (April - June), third trimester (July - September), and fourth trimester (October - December). Rainy season in Pangalengan occur on the first, second, and fourth trimester. Dry season in Pangalengan occur on the third trimester. Diseases that were suspected to positively correlated with rain fall were mastitis, laminitis, and ketosis. Diseases that were suspected to negatively correlated with rain fall were downer cow syndrome. Diseases that were not suspected to correlate with the rainfall were arthritis, hypocalcemia, ruminal acidosis, enteritis, indigestion, and pneumonia.

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.
