Judul: Case Study of Fetotomy and Cesarean Section Techniques to Resolve Dystocia in Mare
Abstrak: Distokia didefinisikan sebagai persalinan yang berlangsung lama atau sulit dan bisa disebabkan oleh kelainan pada fetus atau induk. Penanganan yang cepat dan aman perlu diterapkan untuk membantu persalinan agar nyawa induk dan anak kuda terselamatkan. Tujuan studi kasus ini untuk mengetahui penyebab terjadinya distokia pada pasien rujukan seekor kuda Sandel bunting primipara serta penanganannya. Pemeriksaan per vaginal menunjukkan fetus sudah mati dalam presentasi longitudinal posterior, posisi dorsosakral dan postur unilateral hock flexion. Distokia pada kasus ini disebabkan oleh maldisposisi fetus dan disproporsi fetopelvik. Penanganan awal dilakukan dengan mutasi fetus dan fetotomi pada bagian distal dari persendian tarsus fetus, upaya penanganan tidak berhasil mengeluarkan fetus. Penanganan dilanjutkan dengan operasi caesar. Kuda diberi anestesi general dan operasi dilakukan dengan pendekatan ventral midline. Setelah fetus dan plasenta diangkat, kuda diberi terapi obat antibiotik, analgesik dan antiradang yang dilanjutkan sampai seminggu pasca operasi. Tidak ditemukan adanya komplikasi pada hari ke-7 pasca operasi caesar pada induk kuda., Dystocia is defined as labor that is prolonged or difficult and can be caused by abnormalities in the fetus or mare. Fast and safe handling needs to be applied to assist the delivery so that the lives of the mare and foal are saved. The purpose of this case study is to determine the cause of dystocia in a referral patient of a primipara pregnant Sandel horse and its treatment. Vaginal examination revealed dead fetus in posterior longitudinal presentation, dorsosacral position and unilateral hock flexion posture. The dystocia in this case is caused by fetal maldisposition and fetopelvic disproportion. Initial treatment was carried out with fetal mutation and fetotomy at the distal part of the fetal tarsus joint, this treatment did not succeed in expelling the fetus. The treatment was continued by caesarean section. The horse was given general anesthesia and the surgery was performed by using a ventral midline incision. After the fetus and placenta were removed, the horse was given antibiotic, analgesic and anti-inflammatory drug therapy which was continued for up to a week postoperatively. No complications were found on the 7th day after caesarean section in the mare.

Judul: Sectio Caesarea Operation Technique and Placenta Collection in Pig (Sus scrofa domestica)
Abstrak: Penelitian ini bertujuan mempelajari teknik operasi sectio caesarea yang tepat dalam rangka koleksi plasenta untuk koleksi sel punca epitalia amnion. Babi dengan usia kebuntingan ± 100 hari dan berat badan 230 kg dipuasakan selama 8 - 12 jam. Babi dianestesi dengan anestesi kombinasi Ketamin dan Xylazin kemudian dibaringkan dengan posisi lateral recumbency. Pendekatan bedah dilakukan melalui fossa paralumbar sebelah kanan, operator membuat sayatan kulit secara vertikal sepanjang 20 cm. Insisi dilanjutkan melalui kulit, jaringan adiposa subkutan, otot perut, jaringan adiposa subperitoneal, dan peritoneum. Rongga perut dieksplorasi untuk menemukan uterus. Proses koleksi plasenta dilakukan dengan membilas plasenta menggunakan larutan NaCl fisiologis, kemudian plasenta diletakkan pada media transport. Lokasi insisi pada fossa paralumbar ini dipilih dengan pertimbangan bifurkasi uterus dapat dicapai dan sayatan pada bagian tersebut dapat dilakukan, Jaringan selaput plasenta yang sudah dipisahkan dan dibilas menggunakan NaCl fisiologis dimasukkan kedalam media transport berisikan media kultur dubecco’s modified eagle medium (DMEM), antibiotic-antimycotic 3%, dan fetal bovine serum (FBS) 10%. pertimbangan pemilihan lokasi insisi, kombinasi anestesi, hingga teknik pengeluaran fetus serta pemilihan media transport yang tepat untuk koleksi selaput plasenta menentukan keberhasilan.

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.
