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: 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: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
