Judul: Analisa Termal pada Rancang Bangun Reaktor Pirolisis untuk Memproduksi Bahan Bakar Minyak dari Limbah Plastik
Abstrak: The increasing amounts of plastic wastes generate enormous environmental problems. The pyrolysis can potentially be used to convert plastics into valuable chemicals and fuels. Almost all of the pyrolysis experiments conducted in laboratory condition, and the heat transfer is not investigated. The objectives of this study were to design temperature profile model using Computational Fluid Dynamics (CFD) and analyze its temperature distribution. Reactor was designed as an experimental set-up. For performance test, temperature was maintained in 5 difference level with 3 hours of production process. The result showed that the highest fuel yield produced from 450 pyrolysis temperature with 21.32 g of fuel yield. Each level of temperature degrees have almost similar temperature distribution pattern with temperature decreased vertically to the top of reactor. The result showed that validation using CFD simulation was approaching the value of temperature measurement on reactor.

Judul: Konversi Limbah Plastik Dari TPS 3R Kota Bogor Menjadi Bahan Bakar Minyak Menggunakan Metode Pirolisis
Abstrak: Pirolisis dan degradasi termal merupakan metode alternatif untuk proses daur ulang akhir limbah plastik menjadi bahan bakar minyak. Penelitian bertujuan untuk melakukan pengukuran bangkitan sampah plastik di TPS 3R, menentukan kelayakan ekonomi proses pirolisis, dan menentukan jenis plastik yang paling produktif dalam proses pirolisis. Penelitian berlangsung pada bulan Februari hingga Mei 2020 menggunakan data primer hasil pengukuran di lapangan. Sampah plastik yang digunakan dalam proses pirolisis merupakan lima jenis plastik dari TPS 3R Kota Bogor yaitu low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene (PP), polyethylene terephthalate (PET), dan polystyrene (PS). TPS 3R Cipaku Kota Bogor melayani 2044 jiwa. Bangkitan sampah plastik PET, HDPE, LDPE, PP, dan PS pada TPS 3R Cipaku berturut-turut 1,2; 2,8; 2,0; 1,5; dan 0,3 (g/jiwa/hari). Berdasarkan hasil pirolisis, jenis plastik yang menghasilkan volume BBM tertinggi hingga terendah secara berturut-turut yaitu LDPE, PS, PP dan PET. Secara keseluruhan, keempat jenis plastik yang digunakan dalam proses pirolisis tidak layak dalam segi ekonomi (BCR<1).

Judul: Manajemen Pemeliharaan Kuda (Equus caballus) Untuk Upacara Kenegaraan Dan Sarana Kesenjataan Di Detasemen Kavaleri Berkuda (DenKavkud) TNI-AD Parongpong
Abstrak: Cavalry Horse Detachement (Denkavkud) Indonesian National Army-Cavalary Parongpong is one of the Indonesian military units that utilize the horse and train it as a means of purpose of formal state ceremony and armed forces. Skills possessed by the horse cavalry was the result of care management and specialized training provided by the trainer. Aspects of care management are breeding, feeding, and management. Horses that are kept in the Denkavkud, Parongpong are stallions, mares, foals, and military horses. Total populations of horses at Denkavkud are 183 horses. Besides commited horse training (remonte), Denkavkud also did breeding program to produce horses that can be trained and used as a military horse. There are some issues contained in Denkavkud, such as some of the nutrients needed by the horses not being met from feed given. One of these is crude protein and lysine. Lactation mares was crude protein and lysine deficiency. The number of death in 2010 is higher than previous years. Based on the number of horses that died from January until June 2010 is 11 horses. The average mortality was caused by colic. Colic is caused by excessive eating, excessive drinking during hot, moldy food, and even by investment roundworms. Animal welfare in Denkavkud can be enhanced by improvement of feed given and improving the health of livestock through improved sanitation.
