Abstrak: The simplest way of irrigation is put the water source higher than the field so that the design of irrigation system required the topographic mapping. The aims of this study is to make the topographic map of ICRR, land leveling designing, and analyzing the flow scheme. The results could be used as information and reference for planning and design of irrigation infrastructure in ICRR. Theodolite is used for mapping and the data obtained is processed with Microsoft Excel. The topographic map was made using Surfer and ArcMap. The highest elevation results is 15.611 meters above sea level, while the lowest elevation is 9.224 meters above sea level. The total area of ICRR measured with AutoCAD is 323.764 ha while using ArcMap the area is 331.345 ha. In the land leveling design, the volume of plow layer were taken by 1268183.2 m3 whereas the volume of the foundation layer from the process of cutting and banking is + 964128 m3. The flow scheme in ICRR generally leads to the north and south of the field, but in some parts is irregular. The flow scheme created from the land leveling design is more regular and runs to the north and south of the field.

Judul: Perencanaan dan Perancangan Saluran Drainase Daerah Irigasi di Balai Besar Penelitian Tanaman Padi Subang, Jawa Barat.
Abstrak: Drainage is one of the technical actions to reduce excess water from rain water, seepage, or excess irrigation water on an area so it can function optimally. The purpose of this research are designing drainage channels, designing channels dimension, and modelling planned drainage channels. This research was conducted during months of February to May 2015 at BB Padi, Sukamandi, Subang. The stage of this research are depiction of topographic maps, determination the location of drainage channels, determination of runoff discharge design and drainage channel dimensions, planning sewers, evaluation the performance of drainage channel. Soil texture used i.e. sandy loam. The distance between the drainage channels were designed every 200 m in accordance with the draft consolidation using reference layout of rice fields in Japan. The direction of water flow leads to the North and South, with the main drainage, tertiary drainage, ii and Taman Burung Sukamandi as a downstream of the water flow. Rainfall distributions design with Gumbel method used for a 2 year period (76.25 mm). Stream runoff is planned in each plot. Channel drainage system construction with open channels are not resistant to erosion. The intersection between the channel and the JUT branch cause the need of culvert planning. The design of the channel dimensions made uniform in both the upper and lower channels to sewer plans Evaluation of channel plan performance assessment was done as a channel drain water runoff.

Judul: Pengaruh vaksin aktif dan inaktif terhadap kekebalan dalam pencegahan penyakit newcastle pada ayam
Abstrak: Penyakit Newcastle adalah penyakit yang bersifat infeksius dan kontagius yang menyerang unggas terutama ayam dan kalkun; menimbulkan kematian, penurunan produksi dan kwalitas telur sehingga menimbulkan kerugian ekonomi yang besar; disebabkan oleh paramyxovirus yang termasuk ke dalam golongan virus yang berinti asam ribonukleat. Virus penyebab penyakit ini terdiri atas beberapa galur yaitu velogenik, mesogenik dan lentogenik. Vaksinasi adalah salah satu cara untuk mencegah timbulnya penyakit dan kerugian yang ditimbulkannya. Vaksin terdiri atas vaksin aktif dan inaktif atau vaksin dalam emulsi minyak. Vaksinasi pada umur dini adalah cara yang paling baik dilakukan. Umur ayam yang tepat mulai dilaksanakan vaksinasi adalah pada umur 4 hari, karena pada saat ini titerantibodi asal induk sudah mulai turun dan kondisi ayam sudah mulai kuat untuk dilakukan vaksinasi jika melakukannya pada ayam umur sehari. ...
