Judul: Identifikasi Hijauan Makanan Ternak dan Analisis Potensi Wilayah untuk Pengembangan Usaha Peternakan Domba di Pesisir Pantai Utara Kecamatan Gebang, Kabupaten Cirebon, Provinsi Jawa Barat
Abstrak: Selain digunakan untuk areal hutan pantai dan pariwisata, kawasan pesisir pantai juga dapat kita manfaatkan untuk pembukaan lahan peternakan terutama peternakan domba. Penelitian ini bertujuan untuk mengidentifikasi rumput lokal yang tumbuh di pesisir pantai utara Kecamatan Gebang serta menganalisis potensi wilayah pesisir pantai utara Kecamatan Gebang guna pengembangan usaha peternakan ruminansia khususnya ternak domba dengan menggunakan analisis SWOT dan anlisis Kapasitas Penambahan Populasi Ternak Ruminansia (KPPTR) berdasarkan Nell dan Rollinson. Hasil dari analisis komposisi botani berdasarkan metode “dry weight rank” menunjukkan bahwa hijauan lapang yang paling banyak terdapat pada zona-1 adalah Xerochloa cheribon (57,03%), komposisi botani hijauan lapang pada zona-2 didominasi oleh rumput Cynodon dactylon (41,83%), sedangkan pada zona-3, hijauan lapang yang paling mendominasi berdasarkan komposisi botani adalah Paspalum conjugatum (paitan) dengan persentasi komposisi botani sebesar 43,39%. Hasil analisis KPPTR Nell dan Rollinson menunjukkan bahwa Kecamatan Gebang masih memiliki potensi penambahan ternak ruminansia sebanyak 862,87 satuan ternak atau dengan kata lain penambahan populasi ternak domba dewasa yang dapat dilakukan di Kecamatan Gebang adalah sebanyak 6235 ekor. Berdasarkan analisis SWOT, Kecamatan Gebang berada pada posisi agresif, sehingga strategi yang harus dilakukan dalam pengembangan ternak ruminansia adalah mendukung kebijakan pertumbuhan yang agresif.

Judul: Analisis Potensi dan Pemanfaatan Hijauan Pakan pada Peternakan Domba Rakyat Desa Randobawa Ilir Kecamatan Mandirancan, Kabupaten Kuningan, Jawa Barat
Abstrak: Randobawa ilir is one of the villages in Kuningan Regency where found sheep breeding farm. The aim of this experiment was analyzing potential and utilitazion of forage on sheep breeding farm in Randobawa Ilir village as a feed of ruminant forage. This experiment used descriptive analysis, composition botany analysis, analysis of carrying capacity, and diversity analysis. The results of composition of botany showed that the first rank of forage was Eragrostis sp. as many as 14.01%, the second was Digitaria sp. as many as 9.96%, and the third was Mikania micrantha H.B.K. as many as 9.90%. The result of analysis of carrying capacity showed that Randobawa Ilir village still allowed for addition of livestock as many as 129.39 AU. The result of diversity analysis showed that diversity on paddy field higher than farm. The highest importance value on paddy field was Cynodon dactylon L. Pers. as many as 31.53% and the highest importance value on farm was Oplismenus burmannii (Retz.) P. Beauv as many as 68.64%.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
