Judul: Performance of Isa Brown Layer Chickens with The Addition of Different Types of Probiotics in Drinking Water
Abstrak: Probiotik merupakan makanan pelengkap berupa mikroba hidup apatogen yang berfungsi untuk memperbaiki laju pertumbuhan, efisiensi konversi ransum dan kesehatan ternak. Penelitian ini bertujuan mengidentifikasi pengaruh pemberian tiga jenis probiotik yang berbeda dalam air minum terhadap performa ayam petelur. Peubah yang diamati adalah produktivitas meliputi konsumsi pakan, bobot telur, produksi telur, konversi pakan, dan income over feed cost. Penelitian ini menggunakan 20 ekor ayam petelur strain Isa Brown umur 27-31 minggu. Metode penelitian menggunakan rancangan acak lengkap (RAL) yang terdiri dari 4 perlakuan dengan 5 ulangan yaitu P0 (air minum tanpa probiotik), P1 (air minum dengan probiotik Bioterna 1 mL/500 mL air), P2 (air minum dengan probiotik Gracimax 1 mL/500 mL air) , dan P3 (air minum dengan probiotik EM4 1 mL/500 mL). Performa produksi ayam petelur strain Isa Brown pada penelitian ini menunjukkan bahwa ayam yang diberikan probiotik Gracimax memiliki nilai konversi pakan terendah dan nilai income over feed cost yang tinggi., Probiotics are complementary feeds in the form of live, pathogenic microbes that function to improve growth rates, ration conversion efficiency and livestock health. The objective of this study is to identify the effect of giving three different types of probiotics in drinking water on the performance of laying hens. The observed variables were productivity including feed consumption, egg weight, egg production, feed conversion, and income over feed cost. This study used 20 laying hens strain Isa Brown aged 27-31 weeks. The research method used a completely randomized design (CRD) consisting of 4 treatments with 5 replications, namely P0 (drinking water without probiotics), P1 (drinking water with Bioterna probiotics 1 mL/500 mL water), P2 (drinking water with Gracimax probiotik 1 mL/500 mL water), and P3 (drinking water with probiotic EM4 1 mL/500 mL). The production performance of laying hens Isa Brown strain in this study showed that the chickens given the Gracimax probiotic had the lowest feed conversion value and the high income over feed cost value.

Judul: Evaluation of Multi Strain Probiotics supplementation on Performance and Egg Quality of Isa Brown Laying Hens Aged 31-32 Weeks.
Abstrak: Probiotik merupakan mikroorganisme hidup yang dapat memberikan efek menguntungkan pada saluran pencernaan inang. Penelitian ini bertujuan mengevaluasi pengaruh pemberian probiotik protexin yang dicampurkan pada pakan dan air minum terhadap performa ayam dan kualitas fisik telur. Metode penelitian menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 4 perlakuan dengan 4 ulangan yaitu P0= Tanpa pemberian probiotik protexin, P1= probiotik protexin dalam pakan 50 g ton-1, P2= probiotik protexin dalam air minum 1 g 4 L-1, P3= probiotik protexin dalam air minum 1 g 30 L-1. Data dianalisis menggunakan Analysis Of Variance (ANOVA), dan dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan bahwa penambahan probiotik protexin dalam pakan 50 g ton-1, air minum 1g 4 L-1 dan 1g 30 L-1 tidak memengaruhi hen day production, produksi telur massa, bobot telur, konversi pakan, dan tidak memengaruhi kualitas telur, namun sangat nyata (P<0,01) meningkatkan konsumsi pakan dan Haugh Unit, pada suhu kandang yang relatif tinggi 27,9-290C penambahan probiotik protexin menghasilkan nilai IOFC lebih tinggi dari pada kontrol, dan dosis probiotik protexin 1g 4 L-1 air minum mampu menghasilkan nilai konversi pakan paling baik dan nilai IOFC tertinggi.

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
