Judul: Analisis Reproduksi dan Potensi Kerbau di Kecamatan Cikalongkulon Kabupaten Cianjur
Abstrak: Cikalongkulon district has potential to develop buffaloes business because this region widely used for rice fields and plantations. The purpose of this research was to analyze the performance of buffalo reproduction, potential improvement, and farmer’s income from buffalo business. Buffalo reproduction performance known by doing interviews, the results that obtained were: 2.32+0.73 years old for the first puberty, 2.53+0.70 years old for the first conception, 3.47+0.72 years old for the first calving, 54.23+30.62 days period of estrous cycle, 4.00+3.89 hari days of estrous cycle, 11.95+0.20 months of gestation time, estrous and conception after 4,00+3.89 months partus, and 1.96+0.47 months of calving interval. Population of buffalo can still be improved, according to Capacity of Additional Ruminant Population (CARP) value of Cikalongkulon district as much as 121.49 AU. Farmers that own buffalo by themselves received the highest income, especially in scale 6-10 head. The highest income is Rp23.793.500.

Judul: Karakteristik reproduksi Kerbau Lumpur (Bubalus bubalis) dan kualitas pakannya pada ketinggian yang berbeda di Kabupaten Cianjur
Abstrak: Development of Indonesian swamp buffalo productivity is less encouraging. Field of observations results, low productivity of buffalo caused by the relatively low reproductive efficiency. Contributory factor in increasing reproductive efficiency, among other ensure the availability of forage high quality. Buffaloes maintenance, highly dependent on the availability of natural forage, based on low or high plateau, because a traditionally. Height difference led to the availability forage high quality be diffirent, so can affect characteristic in reproductive efficiency. Characteristic observation of reproductive were analyzed by first oestrous, pregnancy period, postpartum unoestrous and body condition score. Buffalo at low and high plateau had characteristics of reproduction was not a different, but in terms of body condition score, buffalo at high plateau of relatively better with supported quality forage more than exemplary, lenght of season with availability, and comfort zone.

Judul: Electrochemical Sensor Based on Graphene Oxide/PEDOT:PSS Decorated with AuAg Nanozyme for H2O2 Detection
Abstrak: H2O2 merupakan senyawa penanda hayati keadaan stres oksidatif tubuh sehingga diperlukan metode deteksi H2O2 yang cepat dan akurat. Sensor elektrokimia berbasis nanozyme peroksidase, seperti Au-NPs dan Ag-NPs, menawarkan alternatif metode deteksi yang menjanjikan karena ukuran alat yang kecil, kinerja analitik yang lebih baik, dan efisien biaya. Penelitian ini bertujuan mengembangkan sensor elektrokimia non-enzimatik menggunakan nanopartikel bimetal AuAg pada elektrode karbon kaca yang dimodifikasi dengan komposit grafena oksida dan poli(3,4-etilenadioksitiofena)-poli(stirena-4-sulfonat). Elektrode termodifikasi bimetal AuAg-NPs menunjukkan respons pada H2O2 yang lebih tinggi daripada elektrode termodifikasi monologamnya, dengan respons linear dalam rentang konsentrasi H2O2 75–200 µM, sensitivitas 0,0407 μA μM-1, dan limit deteksi mencapai 25 μM. Elektrode hasil modifikasi menunjukkan keterulangan pengukuran yang baik dan selektif terhadap H2O2. Elektrode yang dimodifikasi berhasil digunakan untuk mengukur kadar H2O2 dalam sampel urine sintetis serta memberikan hasil yang tidak berbeda nyata dengan metode spektrofotometri.
