Abstract

Probiotics is a feed additive in the form of life microorganisms that balance microorganism population in the digestive tract. This research was conducted to study the effect of addition of probiotics product into drinking water on performance. One hundred and fifty birds of day old chicks (DOC) of “Hybro-AM”strain were divided into 5 groups of treatments. The treatments were R0 (control diet+ drinking water without probiotics), R1 (R0 + Temban), R2 (R0 + Biolacta), R3 (R0 + Biovet), and R4 (commercial diet). Chicken were given diet and drinkingwater ad libitum. Feed intake, body weight gain and feed conversion were measured weekly and income over feed and cost (IOFC). Local feed (control died) and control with probiotics are feed with self formulation (R0, and R1 – R3). Thecontrol feed ingredient used are corn, rice brand, fish meal, hull soybean mea, palm oil, grit,DCP and premix. Results showed that treatments did not give significant effect (P>0,05) on feed intake, body weight gain and feed conversion. The result of Income Over Feed Cost (IOFC), shows that feed with control diet with probiotics Temban are best alternatif to pressure high price of feed and useable by farmer.

Abstract

Parameter ratios are important information for the ship designer in the preliminary design stages. They can be used as a tool to identify the main parameter of vessel and their other technical characteristics. The information about parameter ratios of mono-hull vessel is currently available in Naval Architecture literatures, but it is not the case for the type of twin-hull vessel called catamaran. Having conducted technical analysis in this research, it has been identified that parameter ratios of passenger catamaran vessel made of FRP has values of L / B ratio from 2.52 up to 3.7, L / D ratio from 5.25 up to 11:24, slenderness ratio (Lwl/BwL) from 9 up to 12. Other values of various parameter ratios like B/T, D/T, L /√ L, and Displacement/L are also discussed.

Abstract

Earthquake with magnitude 7,7 on the Richter scale happened on 17 July 2006 in Indian Ocean, south of Ciamis District at 10 kilometer depth. The earthquake has generated tsunami and causing disaster in the coastal areas of Ciamis – Cilacap.More than 500 people died and hundred of buildings were damage. Field investigations showed that inundation along the affected coastal areas of Ciamis – Cilacap depend on the coastal morphology. In the areas with sand ridges the inundation distance were reduced significantly for example only about 150 meter in Widarapayung compared to 500 meter to 1 kilometer in Pangandaran. Damage to buldings depend on the building constructions. Wooden buildings were easily swept away by the tsunami waves. Concrete buildings without reinforced were heavily or completely damage compared to more withstand reinforced concrete buildings.
