Judul: Desain Perbaikan Saluran Drainase di Cluster Palem Perumahan Bumi Adipura Kota Bandung
Abstrak: Kota Bandung menjadi kota yang rawan terjadi banjir karena intensitas hujan yang tinggi dan banyaknya perubahan tataguna lahan yang mengakibatkan berkurangnya daerah resapan air. Penelitian dilakukan pada bulan Maret-Mei di Cluster Palem Perumahan Bumi Adipura Kota Bandung. Penelitian diharapkan memberikan evaluasi dan rekomendasi terhadap jaringan saluran drainase untuk mengatasi banjir di kawasan perumahan menggunakan software EPA SWMM 5.2. Hasil pembahasan menunjukan bahwa Cluster Palem mengalami banjir atau luapan limpasan dari saluran drainase sebanyak 0,041 x 106 Liter dengan dimensi saluran 0,4 × 0,4 m berbahan beton poles. Simulasi EPA SWMM untuk analisis hidraulika menunjukan terdapat beberapa conduit yang mengalami masalah pada kapasitas saluran. Perubahan dimensi saluran drainase pada CN6, CN7, CN10, CN24, CN32, CN34, CN35, CN41, CN42, CN44, dan CN45 membuat jaringan drainase di Cluster Palem tidak mengalami luapan limpasan. Rancangan Anggaran Biaya (RAB) perbaikan saluran drainase diperlukan sebesar Rp. 234.383.000,00 untuk jenis saluran U-Ditch dan Box Culvert, sedangkan jenis saluran cast-in-situ diperlukan biata sebesar Rp. 103.859.000,00 dengan dimensi yang sama yaitu 0,4 × 0,6 m., Bandung City is prone to flooding due to high rainfall intensity and many land use changes that result in reduced water catchment areas. The research was conducted in March-May at Cluster Palem Housing Bumi Adipura Bandung City. The research is expected to provide an evaluation and recommendation of the drainage channel network to overcome flooding in residential areas using EPA SWMM 5.2 software. The results of the discussion show that the Palem Cluster experienced flooding or overflowing runoff from the drainage channel as much as 0.041 x 106 Liters with channel dimensions of 0.4 × 0.4 m made of polished concrete. EPA SWMM simulation for hydraulic analysis, it shows that there are several conduits that experience problems in channel capacity. Changes in the dimensions of the drainage channels at CN6, CN7, CN10, CN24, CN32, CN34, CN35, CN41, CN42, CN44, and CN45 make the drainage network in Cluster Palem not experience overflowing runoff. The Draft Budget Cost (RAB) for the improvement of drainage channels required Rp. 234,383,000.00 for the U-Ditch and Box Culvert channel types, while the cast-in-situ channel type required a budget of Rp. 103,859,000.00 with the same dimensions of 0.4 × 0.6m.

Judul: Evaluasi Sistem Saluran Drainase di Perumahan Pondok Safari Indah, Tangerang Selatan
Abstrak: Perumahan Pondok Safari Indah mengalami banjir beberapa tahun belakangan ini apabila curah hujan tinggi dan durasi hujan lama. Penelitian difokuskan pada lokasi banjir di Blok C dan Blok D Perumahan Pondok Safari Indah. Penelitian bertujuan untuk mengevaluasi kesesuaian saluran drainase dengan debit limpasan yang terjadi. Luas lokasi penelitian sebesar ±3,4 Ha. Data yang digunakan berupa dimensi saluran, elevasi saluran, data curah hujan harian maksimum, peta topografi dan peta tutupan lahan. Data yang diperoleh digunakan untuk pemodelan saluran drainase dengan menggunakan program EPA SWMM 5.2. Setelah dilakukan pengujian pada 4 metode distribusi, maka curah hujan rencana dianalisis dengan distribusi log Pearson III, dan diperoleh curah hujan rencana sebesar 102,58 mm untuk periode ulang 2 tahun. Jaringan saluran drainase yang ada terdiri atas 34 subcatchment (SC), 72 junction node (JN), 71 counduit (CN), dan 1 outfall node (OR). Debit aliran maksimum sebesar 0,157 m3/detik. Dari hasil simulasi kapasitas saluran drainase sesuai dengan debit limpasan tetapi ada 2 saluran yang tidak mampu menampung limpasan. Pada CN 10 dan 11 terjadi luapan karena terdapat sedimen masing-masing setinggi 0,18 m dan 0,15 m. Kapasitas saluran CN 10 sebesar 0,115 m3/detik sedangkan debit simulasi sebesar 0,117 m3/detik. Saluran drainase mampu menampung dan mengalirkan air dengan baik bila dilakukan pembersihan dan pengerukan sedimen pada saluran drainase secara berkala., Pondok Safari Indah Residence has experienced flooding in recent years while the rainfall was heavy and long. The research focused on flood locations in Block C and Block D of Pondok Safari Indah Residence. The study aimed to evaluate the suitability of drainage channels with runoff discharge. The surface of research area was ± 3,4 Ha. This research used data of channel dimension channel elevation, maximum daily rainfall, topographic maps and land cover maps. These data were used for modeling drainage channels using the EPA SWMM 5.2 program. After testing 4 distribution methods, the planned rainfall was analyzed with the log Pearson III distribution, and a planned rainfall of 102,58 mm was obtained for the 2-year rainfall return period. The existing drainage channels system consist of 34 subcatchment (SC), 72 junction nodes (JN), 71 counduit (CN), and 1 outfall node (OR). The maximum flow discharge is 0,157 m3/sec. From the simulation results, the capacity of the drainage channel is in accordance with the runoff discharge, but there are 2 channels that are not able to accommodate runoff. CN 10 and 11 overflowed because there was sediment as high as 0,18 m and 0,15 m respectively. The CN 10 channel capacity was 0,115 m3/sec while the simulated discharge was 0,117 m3/sec. The drainage channel were able to accommodate and drain water properly, if the drainage channels were cleaned and the sediments were dredged periodically.

Judul: Enrichment of organic selenium, inorganic selenium and  vitamin E in quail products through its supplementation in the diet and its potency  of quail eggs as an ingredient in selenium-rich egg juice
Abstrak: This study was aimed to achieve an optimum level of combine organic selenium, inorganic selenium and vitamin E in obtaining the best production and reproduction as well as the highest level of selenium in quail eggs. This study was conducted from January to August 2008. Numbers of observed quails were 720 (360 females and 360 males). The treatments were applied when the quails were six weeks old. Nine treatment diets were: To (commercial diet), T1(0.46 ppm inorganic Se + 43.50 ppm vitamin E), T2 (0.46 ppm inorganic Se + 87.00 ppm vitamin E), T3 (0.92 ppm inorganic Se + 43.50 ppm vitamin E), T4 (0.92 ppm inorganic Se +87.00 ppm vitamin E), T5 (0.46 ppm organic Se + 43.50 ppm vitamin E), T6 (0.46 ppm organic Se + 87.00 ppm vitamin E), T7(0.92 ppm organic Se + 43.50 vitamin E) and T8(0.92 ppm organic Se + 87.00 ppm vitamin E).
