Judul: Prevalensi Fasciolosis dan Paramphistomosis pada Sapi Potong di Sekolah Peternakan Rakyat (SPR) Wilayah Kabupaten Muara Enim Provinsi Sumatera Selatan.
Abstrak: Penelitian dengan metode cross-sectional ini bertujuan untuk mengetahui tingkat prevalensi fasciolosis dan paramphistomosis pada sapi potong di Sekolah Peternakan Rakyat (SPR) wilayah kabupaten Muara Enim, Sumatera Selatan. Sebanyak 200 sampel feses segar dikumpulkan dari 3 SPR yaitu Muara Tigo Manunggal, Panca Muara Lengi dan Extrans Serasan Berkarya. Analisis koprologik menggunakan metode modifikasi sedimentasi-filtrasi. Prevalensi Fasciolosis dan Paramphistomosis di setiap desa pada setiap SPR dianalisis secara deskriptif. Adapun perbedaan prevalensi di antara 3 SPR tersebut dianalisis statistik menggunakan Chi-square. Hasil penelitian menunjukkan bahwa sebanyak 50 sapi potong (25%) terinfeksi Fasciola (2,5%) dan Paramphistomum (22.5%). Prevalensi paramphistomosis menunjukkan perbedaan nyata di SPR Muara Tigo Manunggal (30%), di Panca Muara Lengi (6%), dan di Extrans Serasan Berkarya (21%), tetapi prevalensi fasciolosis secara beturut-turut adalah 3%, 0% dan 5% tidak menunjukkan perbedaan nyata.

Judul: Incidence of Fasciolosis and Paramphistomosis in Beef Cattle of North Sumatra Province from 2019-2020
Abstrak: Fasciolosis dan paramphistomosis adalah penyakit yang disebabkan oleh parasit cacing yang menyerang hati dan rumen dimana penularannya dapat melalui siput. Penyakit tersebut dapat menyebabkan kerugian baik dari segi kesehatan maupun ekonomi. Penelitian ini bertujuan menganalisis kejadian fasciolosis dan paramphistomosis serta menghitung kenaikan populasi pada sapi potong di Provinsi Sumatra Utara. Data sekunder mengenai helminthiasis ini diperoleh dari Balai Veteriner Medan dari tahun 2019-2020 dan dilengkapi dengan data dari Dinas Ketahanan Pangan dan Peternakan Provinsi Sumatra Utara. Total populasi sapi potong di Provinsi Sumatra Utara pada tahun 2019 sebanyak 864.680 ekor dan pada tahun 2020 sebanyak 891.868 ekor yang tersebar di 33 kabupaten/kota. Survailans yang dilakukan oleh Balai Veteriner Medan meliputi 22 kabupaten/kota. Data yang diperoleh disajikan secra deskriptif dan diolah menggunakan software Microsoft Excel® 2007. Hasil penelitian menunjukkan bahwa tingkat kejadian paramphistomosis lebih tinggi daripada fasciolosis, dengan persentase berturut-turut sebesar 48,49% dan 5,48%. Berdasarkan hasil tersebut, dapat disimpulkan bahwa sapi potong di Provinsi Sumatra Utara lebih banyak menderita paramphistomosis daripada fasciolosis. Sementara itu, dari segi pertumbuhan populasi sapi potong di provinsi Sumatra Utara tetap mengalami peningkatan dari tahun 2019-2020., Fasciolosis and paramphistomosis are diseases caused by worm parasites that attack the liver and rumen where the transmission can be through snails. The disease can cause losses both in terms of health and economics. This study aims to analyze the incidence of fasciolosis and paramphistomosis and calculate the population increase in beef cattle in North Sumatra Province. This secondary data on helminthiasis was obtained from the Medan Veterinary Center from 2019-2020 and is complemented by data from the Food Security and Livestock Service Office of North Sumatra Province. The total population of beef cattle in North Sumatra Province in 2019 was 864.680 heads and in 2020 as many as 891.868 heads spread across 33 districts/cities. The surveillance carried out by the Medan Veterinary Center covers 22 districts/cities. The data obtained were presented descriptively and processed using Microsoft Excel® 2007 software. The results showed that the incidence of paramphistomosis was higher than fasciolosis, with the percentages being 48,49% and 5,48%, respectively. Based on these results, it can be concluded that beef cattle in North Sumatra Province suffer more from paramphistomosis than fasciolosis. Meanwhile, in terms of population growth, beef cattle in North Sumatra province continued to increase from 2019-2020.

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.
