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: Drainage Channel Improvement Design in Griya Katulampa, Bogor City
Abstrak: Pembangunan yang terjadi di Perumahan Griya Katulampa mengakibatkan berkurangnya lahan resapan air dan bedampak pada salah satu infrastruktur yaitu saluran drainase. Tujuan penelitian ini adalah untuk mendesain perbaikan saluran drainase di perumahan Griya Katulampa untuk mengatasi banjir. Desain perbaikan dibuat dalam bentuk gambar teknik dan dihitung rencana anggaran biaya yang diperlukan. Penelitian ini menggunakan curah hujan harian maksimum selama 10 tahun untuk wilayah Kota Bogor. Hasil analisis dengan metode distribusi Gumbel dengan pengujian chi-kuadrat dan Smirnov-Kolmogorov menunjukkan curah hujan rencana periode ulang 5 tahun sebesar 159.34 mm. Hasil pemodelan jaringan drainase menggunakan pemodelan EPA SWMM 5.2 menunjukkan bahwa lokasi penelitian mengalami luapan pada salah satu saluran dari 117 buah saluran, yaitu saluran CN29. Kapasitas debit saluran eksisting yang didapatkan dari perhitungan sebesar 0.017 m3 /detik, sedangkan hasil dari simulasi debit yang terjadi sebesar 0.028 m3 /detik. Perbaikan saluran drainase dilakukan dengan menambahkan kedalaman saluran sebesar 0.15 m, sehingga saluran memiliki kedalaman baru sebesar 0.35 m. Perbaikan saluran CN29 menghasilkan kapasitas saluran baru sebesar 0.033 m3 /detik, sehingga mampu menampung debit aliran yang terjadi. Keperluan anggaran biaya untuk perbaikan saluran sebesar Rp. 13,114,899., The construction in Griya Katulampa residence has resulted in a reduction of water catchment areas and had an impact on the infrastructures, in particularly drainage channels. The purpose of this study was to design a drainage channel improvement at Griya Katulampa Residence to overcome flooding. Improvement design made in engineering drawings and the cost requirement was calculated. This study used 10 years maximum daily rainfall of Bogor City area. The results of the Gumbel distribution method with the chi-square and Smirnov-Kolmogorov tests showed that the planned rainfall of 5 year return period was 159.34 mm. Modeling result using the EPA SWMM 5.2 model showed that the study site experienced an overflow in one of the 117 channels, namely the CN29 channel. The discharge capacity of the existing channel was 0.017 m3 /s while the simulated discharge was 0.028 m3 /s. Improvement of the drainage channel is carried out by adding a channel depth of 0.15 m, so that the channel has a new depth of 0.35 m. Improvements to the CN29 channel resulted in a new channel capacity of 0.033 m3 /s, and it was able to accommodate the flow discharge that occurred. The budget requirement for channel improvement was IDR. 13,114,899.

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).
