Judul: Study of Stereotypical Behavior of Horses and Stable Condition in Karangpandan Sub District, Karanganyar, Central Java
Abstrak: Perilaku stereotip adalah pola perilaku abnormal yang berulang dan tidak jelas tujuan atau fungsinya. Contoh perilaku stereotip pada kuda yaitu: crib-biting, weaving, box-walking, wood-chewing, dan wind sucking. Tujuan dari penelitian ini untuk mengidentifikasi jenis perilaku stereotip pada kuda serta kondisi lingkungan kandang di salah satu Stable di Kecamatan Karangpandan. Perilaku stereotip pada kuda yang menjadi data utama didapatkan dengan cara pengamatan langsung. Pengambilan data pendukung dilakukan dengan cara pengamatan langsung dan wawancara dengan pelatih kuda. Analisis data dilakukan dengan menentukan persentase kejadian perilaku stereotip, mengidentifikasi kondisi lingkungan yang kemudian dijelaskan secara deskriptif. Hasil pengamatan ditemukan perilaku stereotip weaving, crib-biting, nippling, dan tongue biting. Persentase perilaku stereotip tertinggi yaitu perilaku tongue bitting dan persentase terendah ditunjukkan perilaku Nippling. Berdasarkan kandang, persentase perilaku stereotip tertinggi pada kuda berada di kandang D. Interaksi sosial antar kuda pada Stable ini sudah terpenuhi dengan adanya paddock. Pengobatan dan pencegahan perilaku stereotip dapat dilakukan dengan meningkatkan waktu latihan, sosialisasi antar kuda, dan waktu makan., Stereotype behaviour is a behaviour pattern that is repetitive and has no obvious goal or function. The Examples of stereotypical behavior in horse : crib-biting, weaving, box-walking, wood-chewing, and wind sucking. The purpose of this study was to identify the type of stereotypical behaviour in horse and stable condition. Equine stereotype behaviour, the primary data was obtained by direct observation the horse. Support data was obtained by observing the stable and interviewing the horse trainer. Data analysis was done by determining the percentation, identify the stable condition, and then describe the result. The result was found stereotype behavior, weaving, crib-biting, nippling, and tongue biting. The highest stereotypical behaviour is tongue bitting and the lowest percentage is nippling. Based on the stable, the highest percentage of stereotypical behaviour found in stable D. Social interaction between horses is fulfilled by the paddock. Medicaion and prevention are made by increasing training time, socializing time, and feeding time

Judul: Hubungan antara kejadian kolik dan faktor-faktor resiko kolik pada kuda   : Kajian kasus pada stable di Bogor dan Tanggerang
Abstrak: Kajian ini bertujuan untuk mengetahui hubungan antara faktor-faktor resiko kolik dan kejadian kolik pada stable di Bogor dan Tangerang. Total populasi yang di ambil adalah 201 ekor kuda. Metode pencarian data dilakukan dengan cara pengamatan langsung, wawancara dan catatan medis dari setiap stable. Pengamatan terhadap hubungan antara faktor-faktor resiko kolik dan incidence rate kolik pada kuda ini disajikan secara deskriptif. Hasil kajian menunjukkan bahwa kejadian kolik pada kuda di Arthayasa Stable, Dwima Turangga Equestrian Club dan Pamulang Stable ada hubungannya dengan frekuensi pemberian konsentrat, keteraturan aktifitas sehari-hari, frekuensi pengikiran gigi, sejarah kejadian kolik, jenis kelamin dan umur. Sedangkan lamanya waktu pengumbaran dan selang waktu pemberian anthelmintika tidak berhubungan dengan kasus kejadian kolik pada kuda.

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.
