Judul: Analysis The Incidence of Surgical Disease in Friesian Holstein in Koperasi Peternakan Bandung Selatan Pangalengan in 2014-2019
Abstrak: Friesian Holstein (FH) merupakan sapi perah yang banyak dipelihara di Koperasi Peternakan Bandung Selatan (KPBS) Pangalengan. Berbagai penyakit sering menyerang sapi jenis ini. Penyakit bedah merupakan salah satu penyakit yang sering dilaporkan pada ternak sapi di KPBS Pangalengan. Studi kasus ini bertujuan menganalisis tingkat kejadian penyakit bedah pada sapi perah dan dugaan hubungannya dengan cuaca serta faktor-faktor lainnya di KPBS Pangalengan pada tahun 2014-2019. Studi kasus ini dapat memberikan pengetahuan mengenai kejadian penyakit bedah pada sapi perah dan menjadi acuan untuk peningkatan manajemen, pengelolaan kesehatan hewan ternak serta upaya pencegahan penyakit pada ternak. Data kejadian penyakit dan kondisi curah hujan dikelompokkan berdasarkan trimester waktu dalam 12 bulan. Januari-Maret dikelompokkan ke dalam trimester pertama, April-Juni dikelompokkan trimester kedua, Juli-September dikelompokkan trimester ketiga dan Oktober-Desember dikelompokan ke dalam trimester keempat. Data kejadian penyakit diperoleh dari laporan praktik lapang mahasiswa Program Profesi Dokter Hewan (PPDH) IPB University di KPBS Pangalengan pada tahun 2014-2019. Hasil analisis data menunjukkan lima kejadian penyakit bedah tertinggi selama periode 2014-2019 adalah displacement abomasum, pododermatitis, timpani rumen, papillomatosis dan perikarditis traumatika. Cuaca diduga memengaruhi kejadian penyakit displacement abomasum dan pododermatitis. Sedangkan penyakit timpani rumen, papillomatosis dan perikarditis traumatika diduga tidak terpengaruh oleh kondisi cuaca., Friesian Holstein (FH) is a dairy cow that is widely maintained in the Koperasi Peternakan Bandung Selatan (KPBS) Pangalengan. Various diseases often attack cows of this breed. Surgical disease is one of the diseases that are often reported in cattle in KPBS Pangalengan. This case study aims to analyze the incidence rate of surgical diseases in dairy cows and their alleged relationship to weather and other factors in KPBS Pangalengan in 2014-2019. This case study can provide knowledge about the incidence of surgical diseases in dairy cows and become a reference for improving management, management of animal health and prevention efforts in livestock. Data on disease events and rainfall conditions are grouped by time trimester in 12 month. January-March is grouped into the first trimester, April-June is grouped into the second trimester, July-September is grouped into the third trimester and October-December is grouped into the fourth trimester. Data on disease occurrence was obtained from the field practice report of students Veterinary Profession Program (PPDH) IPB University at KPBS Pangalengan in 2014-2019. The results of the data analysis showed the five highest incidences of surgical diseases during the period 2014-2019 were displacement abomasum, pododermatitis, ruminal tympany, papillomatosis, and traumatic pericarditis. The weather is thought to affect the incidence of displacement abomasum and pododermatitis. While the disease ruminal tympany, papillomatosis and traumatic pericarditis are thought to be unaffected by weather conditions.

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: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
