Abstrak: The construction of a dam is built crossing river stream for elevating water level. In designing a dam, force field analysis in a dam is needed to ensure a dam can be operated properly. The focus of this research is to analize seepage and uplift pressure in a dam. The objective of this research is quantifying and analyzing the force that occurs in a dam as a reference in designing of a dam construction. The study is located in Sungai Buntu Village, Pedes, Karawang. The analysis is using guideline KP-02 Criteria for Designing Main Dam and KP-06 Criteria for Designing Additioal Structures. Software Geo Studio Seep/w 2004 is used in seepage analysis. The data which are required are soil permeability, and water level at upstream and downstream. The equipments used in this study are soil ring, tape, computer, and calculator. Based on the result of Geo Studio Seep/w 2004 analysis, the quantity of seepage under the Dam is 1,01 x10-8 m3/sec. Based on flow net analysis the quantity of seepage under the Dam is 1,72x10-8 m3/sec and the uplift pressure is 2450 kg/m.

Judul: Analisis Stabilitas Bendung dan Rembesan pada Perencanaan Bangunan Bendung di Desa Sungai Buntu Karawang
Abstrak: Water resources management, especially around the coast in agriculture today is needed to support empowerment in agriculture. The purpose of this study is to analyze the slope stability and seepage weir urugan as design of the weir and in Tegal River, River Buntu Village, Pedes subdistrict, Karawang . The results showed that the weir estimates are appropriate and can be built is a concrete weir with a weir height and weir urugan 1,7 m, 0,95 m high water upstream and downstream water levels 0,75 m . Shear force values and bolster the stability of the concrete weir obtained are still below the safety factor , the slice force and shear force while receiving and not receiving the load of each load is still allowed. The planned dam has a value of soil cohesion 1,8 kN/m3 and angle in the style of 34 . Safety factor for slope stability at 1,815 and seepage discharge that occurs in the soil is equal to 1,7408 x10-4 liter/second.

Judul: Keberadaan Antibodi Asal Induk Newcastle Disease (ND) dan Infectious Bronchitis (IB) pada Broiler yang Divaksinasi Vaksin Rekombinan HVT-IBD
Abstrak: Penelitian ini bertujuan untuk mempelajari keberadaan antibodi asal induk terhadap virus Newcastle Disease (ND) dan Infectious Bronchitis (IB) pada broiler yang divaksinasi dengan vaksin rekombinan Herpesvirus of Turkey (HVT) - Infectious Bursal Disease (IBD). Pada penelitian ini digunakan dua kelompok ayam yaitu: Kelompok Vaksinasi dan Tidak Vaksinasi. Kelompok vaksinasi menerima vaksin rekombinan HVT-IBD pada umur 1 hari. Sampel serum dikoleksi pada umur 3, 6, 9, 12, 15, 19, 22, 26, 29, dan 33 hari. Titer antibodi ND ditentukan dengan uji Hemaglutinasi Inhibisi (HI), sedangkan Enzyme-linked Immunosorbent Assay (ELISA) digunakan untuk menentukan titer antibodi IB. Antibodi ND pada kedua kelompok masih terdeteksi sampai broiler berumur 33 hari, namun titer antibodi ND positif hanya sampai umur 6 hari dan tidak mencapai level protektif. Antibodi IB masih pada level positif sampai dengan umur 6 hari pada kelompok divaksin dan 3 hari pada kelompok tidak divaksin. Hasil penelitian ini mengindikasikan bahwa diperlukan vaksinasi ND pada broiler berumur 3 hari dan vaksinasi IB pada broiler berumur lebih dari 6 hari.
