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: 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: 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.
