Judul: Housing Planning, Drainage and Infiltration Wells Design for Cibungbulang Housing in Bogor Regency
Abstrak: Pertumbuhan masyarakat Indonesia perlu diimbangi dengan penyediaan lahan pemukiman yang baik untuk tempat tinggal. Tujuan penelitian ini adalah merencanakan perumahan dan saluran drainase serta sumur resapan di Perumahan Cibungbulan. Perencanaan didasarkan pada karakteristik tanah, hidrologi, dan topografi lahan. Direncanakan perumahan dibangun dalam 5 klaster dan tersedia tiga tipe persil yaitu tipe 150, tipe 105, dan tipe 70. Tiap klaster memiliki 28 sampai 91 unit persil rumah. Direncanakan saluran drainase primer berpenampang trapesium dengan tinggi saluran 2 m, lebar dasar saluran 1,4 m, dan kemiringan penampang 1,5 untuk CA1 dan CA5. Untuk CA2, CA3, dan CA4 saluran primer dirancang dengan tinggi 1,7 m, lebar dasar 1,2 m, kemiringan penampang 1,5. Pada CA1 saluran sekunder dirancang berbentuk persegi dengan lebar dasar 0,3 m dan tinggi 0,4 m, sedangkan pada CA2. lebar dasar 0,3 m dan tinggi 0,4 m. Pada CA3 dan CA4 dirancang saluran sekunder berbentuk persegi dengan lebar dasar 0,4 m, dan tinggi 0,4 m, sedangkan pada CA5 lebar dasar saluran 0,5 m dan tinggi saluran 0,6 m. Direncanakan sumur resapan berdiameter 0,8 m dengan kedalaman pada CA1, CA2, CA3, dan CA4 berturut-turut sebesar 2,6 m; 2,4 m; 2,6 m; dan 2,6 m. Direncanakan terdapat 10 sumur resapan pada CA1, 8 sumur pada CA2, 9 sumur pada CA3, dan 9 sumur pada CA4.

Judul: Perencanaan Sumur Resapan di Kawasan Pemukiman Perkotaan
Abstrak: Pertumbuhan penduduk yang pesat di Kota Bogor menyebabkan tata guna lahan banyak yang berubah menjadi lahan terbangun, sehingga meningkatkan limpasan dan mengurangi pengisian air tanah. Penelitian ini bertujuan merencanakan sumur resapan berbasis daya dukung sumber daya air di kawasan pemukiman daerah perkotaan. Telah dapat dilakukan penapisan lokasi prioritas sumur resapan berdasarkan kriteria topografi, tutupan lahan, dan aliran sungai. Lokasi prioritas tersebut yaitu di Kecamatan Bogor Selatan dengan DTA Cikaret, Cipakancilan, Cipinang Gading, dan Cisadane. Status DDL-air keempat DTA termasuk kategori “terlampaui” (overshoot). Hasil analisis neraca air menunjukkan surplus neraca air sebesar 1.272,3 mm/tahun dengan persentase limpasan yang relatif besar yaitu 75,7%-95%. Debit limpasan maksimum berkisar antara 31,3 m3/detik s/d 163,7 m3/detik. Telah dapat didesain sumur resapan individu dengan tiga tipe menurut luas atapnya, dengan kedalaman yang seragam 3 m, dan jari - jari 0,4 m-0,6 m. Dengan menggunakan skenario luas atap per pemukiman 10%-40% efektivitas sumur resapan individu diperkirakan berkisar antara 5,4%-39,9%. Total sumur yang diperlukan untuk empat DTA sejumlah 1.450 unit-43.073 unit. Sumur resapan komunal direncanakan terintegrasi dengan saluran drainase jalan lokal, kolektor, dan arteri. Perlu dilakukan penelitian lebih lanjut untuk mengkaji kelayakan dan akseptabilitas masyarakat terhadap pembangunan sumur resapan., The rapid growth in Bogor City has caused a lot of land use to be turned into built-up land, thereby increasing runoff and reducing groundwater recharge. This study aims to plan infiltration wells based on the carrying capacity of water resources (DDL-water) in urban residential areas. It have been done to filter the priority location of infiltration wells based on topography, land cover, and river flow criteria. The priority location are in South Bogor District with Cikaret, Cipakancilan, Cipinang Gading, and Cisadane catchment areas. The DDL-water status of the four catchment areas is in the “overshoot” category. Water balance analysis show an air balance surplus of 1.272,3 mm/year with a relatively large proportion of runoff, which is 75,7%-95%. The maximum runoff discharge ranges from 31,3 m3/s to 163,7 m3/s. It have been done to design individual infiltration wells with three types according to the roof area, with a uniform depth of 3 m, and a radius of 0,4 m-0,6 m. By using the scenario of roof area per settlement 10%-40%, the effectiveness of individual infiltration wells ranges from 5,4%-39,9%. The total wells required for the four catchment areas are 1.450 units-43.073 units. Communal infiltration wells are planned to be integrated with local, collectors, and arteries street drainage channels. Further study is needed to asses the feasibility and acceptability from society of the infiltration well development.

Judul: Systematic Review on Volatile Profile Compound and Its Application in Species Identification for Halal Authentication
Abstrak: Volatilomic is an emerging research area where its rapidness and accuracy in its diagnostic ability have been reported to be promising and also is economically favorable. Meat and meat-based food produces certain composition of volatile compounds which can be utilized in identification of its origin and consequently be used for food authentication. Systematic literature review on various publications was done to evaluate the use of volatiles in identification of meat-based food. This review focuses on the volatile profile compounds, various factors which could affect its production, its extraction and detection method, and its application in meat and meat-based food with a brief background discussing on the possibility on its utilization for halal authentication. The result shows that major component of volatile compounds associated with the aromas of meat are of from aldehydes, ketones and alcohols with each of type of meat having variation in its composition. There is no definite pattern. Most of these volatile compounds are the products of combination of Maillard reaction, Stecker degradation, or interaction of both, as well as thiamine degradation. Commonly used extraction method for meat samples is HS-SPME (Head Space-Solid Phase Microextraction) as it is solventless, having high sensitivity and practical. Main analysis method for detection of the metabolites volatile compounds is Gas Chromatography-Mass Spectrometry and is the most superior out of other method options. As for Halal authentication, there is a potential and possibility of utilizing volatile compound profile of meat species for such purpose but not enough evidence or scientific study to entirely rely on it alone. Therefore, require a further validation technique such as PCR. Further studies need to be conducted revolving utilization of meat volatile compound profiles for halal authentication.
