Judul: Gambaran Histologis Bursa Fabricius dan Limpa Ayam Broiler yang Diberi Ekstrak Temulawak Plus (Curcuma xanthorrhiza Roxb.)
Abstrak: This research was conducted to determine the histomorphological changes of bursa of fabricius and spleen after giving curcuma extract plus. Thirty six of broiler chicken were divided into 4 treatment groups, namely P0 (control), P1 (1 ppm extract of curcuma plus), P2 (3 ppm extract of curcuma plus), and P3 (5 ppm extract of curcuma plus). The observation of the evaluated tissues were done for 3 consecutive weeks. Each treatment group was taken randomly to get its bursa of fabricius and spleen. Both of organ samples then were processed for the histological and observation using a light microscope. The parameters of observation were number of bursa of fabricius follicle, diameter of bursa of fabricius follicle and number of white pulp in spleen. The results indicated that the all of parameters decrease in 3 weeks after giving 3 treatments. The three doses indicate the best result than control. It was concluded that the morphological appearance of bursa of fabricius and spleen could be influenced by using curcuma extract plus at a various dose at the period of 3 week

Abstrak: The curcuma has so many therapeutic advantages such as hepatoprotection, anticarsinogenic, antimicrobial, antioxidant, antihyperlipimedic, and antiinflammatory agent. This research was aimed to know the histological changes of proventriculus, duodenum, and liver of broiler chicken which were given curcuma extract plus multivitamin. A total of 36 broiler chickens were divided into 4 groups (P0, P1, P2, and P3) with 3 replications in each group. P0 was the control group that was given aquadest, while P1, P2, and P3 were given curcuma extract plus at a dose of 1, 3, and 5 ppm, respectively. The treatment was given for 3 consecutive weeks. The observed variables were number of epithelial cells which were cleavaging in the mucosa of proventiculus, number of Goblet cells and Lieberkhun glands in the duodenum, and intact structure of hepatocyte in the liver. The curcuma extract plus influenced the proliferation of epithelial cells in the mucosa of proventriculus, increased the number of Goblet cells and Lieberkhun glands in duodenum, and prevented liver cell damage in the broiler chicken. This histological changes may improve the efficiency of feed digestibility and proventriculus and intestinal mucosal protection of the broiler chicken.

Judul: Pemetaan Tingkat Kerentanan Pantai Terhadap Bencana Tsunami di Wilayah Pantai Pangandaran, Jawa Barat
Abstrak: Indonesia are on the path of seismically active region and can cause a tsunami disaster. One of the area inIndonesia that is prone to tsunami disaster is Pangandaran Coast, West Java on southern coast of Java . One of the prime action in the tsunami disaster mitigation is to create a map of coastal vulnerability to the tsunami disaster. The research was conducted from April to December 2013 including three districts in Pangandaran. Analysis of tsunami vulnerability assessment was performed by using merger or overlay method with Geographic Information Systems (GIS). The parameters that used to analyze the vulnerability of tsunami is elevation, topography, landuse, coastal border, and the river banks. The vulnerability level is divided into five classes, that is very high, high, medium, low , and very low . From the entire area of research, Pananjung village, Babakan, Pangandaran (Pangandaran sub-district) and village Sukaresik and Cikembulan (Subdistrict Sidamulih) are the areas that have very high levels of tsunami vulnerability amounting to 737.703 ha. While the areas that have low vulnerability are Pagergunung Village, Putrapinggan, Kersaratu region with an area of 4816.204 hectare
