Judul: Penentuan Lokasi, Luas, dan Volume Genangan Air Sebagai Potensi Cadangan Airtanah di Perumahan Tamansari Persada, Bogor
Abstrak: The changes of the green land-use as retention area to become housing area, will cause problems like enhancement of run-off, reduction of water infiltration to the land, as well as puddle and flood if water volume increases in some area. A study was conducted with the objective to determine the location, area, and volume of puddles at Tamansari Persada Residential, Bogor as groundwaters storages potential. The procedure of sampling and analysis of the data were determination of fixed location of puddles, determination of coordinate points for area and volume of puddles, and analysis of the data by aSurfer 8’s software and Gridding Krigging Method. According the research result from March to April 2013, there were three fixed puddles locations at Palm Cluster and routine flood occured when rain was falling and the maximum volume and area puddles for the first location were 0.11 m3 and 6.57 m2, the second location were 0.26 m3 and 18.82 m2, and the third location were 0.35 m3 and 20.77 m2. Generally, there are correlation from enhancement of lowest elevation, areas, and volumes of puddle and have been proved by Linear Regresion Method. From this method will produced puddle potential formula and the value of determination coefficient (R2) closer to 1. The location, areas, and volume of puddles could becoming reference of puddles potential and absorbed to the ground as an groundwater.

Abstrak: Runoff is affected by various factors, i.e., meteorological factor represented by precipitation and regional flow factor stated the regional drainage physical properties. The change in land characteristics from natural land into developed land will reduce the absorption function in catchment areas and increase runoff. The situation could lead to the occurrence of flood if the planning of drainage at a residential area is not good. It often happens in Tamansari Persada Residence in Bogor. A study was conducted with the objective to identify the direction of runoff (incoming flow and outgoing flow) and to predict runoff in the Tamansari Persada Residence. The methods used in this study were literature review and field study. The material used included Google Earth satellite image acquisition of September 12, 2012, the rainfall data from Atang Sanjaya Weather Station at Bogor from 2003 until 2012 and topographic contour map of the residence. From the observation and analysis, the direction of runoff in the Tamansari Persada Residence followed the topographic from the south to the north. The total discharge of runoff reached 1.31 m3 s-1 in the area of 27.98 ha.

Judul: Sifat Fisik dan Kimia Daging Kelinci Hyla Hycole dan New Zealand White.
Abstrak: Hyla dan hycole merupakan kelinci pedaging unggul dengan laju pertumbuhan dan tingkat prolifik yang tinggi. Kedua kelinci tersebut masih relatif baru dikembangkan di Indonesia, sedangkan kelinci new zealand white telah adaptif dan populer sebagai kelinci pedaging. Penelitian ini bertujuan untuk membandingkan kualitas daging kelinci hyla, hycole dan new zealand white berdasarkan sifat fisik dan kimia. Kelinci mulai dipelihara pada kisaran rataan bobot 2 000-2 256 g hingga mencapai bobot akhir 2 700-3 500 g dengan pemberian kualitas pakan yang sama (protein 17.8% dan energi 4098 kcal). Otot longissimus dorsi digunakan sebagai bahan uji sifat fisik, sedangkan daging dari setiap potongan komersial digunakan untuk uji sifat kimia. Hasil uji sifat fisik menunjukkan bahwa rataan nilai pH akhir daging kelinci hyla, hycole dan new zealand white adalah 5.67, sedangkan untuk susut masak 38.27-39.72%, keempukan 3.10-3.70 kg cm-2 dan DMA 23.75-28.18%. Hasil uji sifat kimia menunjukkan nilai rataan persentase kadar air 75.00-77.26%, abu 1.08-1.14%, lemak 3.29-4.05%, protein 18.15-19.64% dan gross energy 1 327.00-1 521.20 kcal kg-1. Kelinci hyla, hycole dan new zealand white memiliki kualitas daging yang sama baiknya.
