Judul: Studi Timbulan dan Komposisi Sampah Domestik Sebagai Perancangan Teknis Operasional Persampahan PLTU Banten 1 Suralaya
Abstrak: Studi timbulan dan komposisi sampah diperlukan untuk mengetahui data timbulan dan komposisi sampah serta untuk menentukan pengelolaan sampah yang sesuai. Tujuan dari tugas akhir ini adalah mengidentifikasi timbulan dan volume timbulan sampah domestik, menganalisis komposisi sampah domestik dan menentukan alternatif perancangan teknis operasional sampah di PLTU Banten 1 Suralaya. Penelitian ini dilakukan pada bulan Juni – November 2019 dan data diperoleh dari PLTU Banten 1 Suralaya. Berdasarkan data yang telah didapatkan diperoleh komposisi sampah terdiri dari sisa makanan, daun, plastik, kain, kertas dan botol. Komposisi sampah terbesar adalah sisa makanan sebesar 38.1% dan yang terkecil adalah botol plastik sebesar 0.38%. Nilai timbulan terbesar berasal dari gedung CWP seberat 1.18 kg/orang/hari dan volume sebesar 10.56 liter/orang/hari. Nilai timbulan terkecil berasal dari gedung administrasi seberat 0.04 kg/orang/hari dan volume sebesar 0.45 liter/orang/hari. Alternatif pengelolaan sampah di PLTU Banten 1 Suralaya dilakukan dari hulu sampai hilir, dari sumber sampah sampai ke pembuangan akhir.

Judul: Design of TPS 3R in Bulumanis Kidul Village, Margoyoso District, Pati Regency
Abstrak: Permasalahan persampahan terjadi pada Desa Bulumanis Kidul sehingga pemerintah desa mengadakan pengelolaan sampah, tetapi masih belum berjalan dengan efektif. Penelitian ini bertujuan merencanakan sistem pengelolaan sampah dari sumber hingga TPS 3R. Penelitian menggunakan metode kuantitatif. Hasil pengukuran timbulan sampah sebesar 2,25 L/jiwa.hari dengan komposisi berdasarkan massa meliputi sampah organik sebesar 55,49%, kertas 9,77 %, plastik 19,50%, botol plastik 4,20%, kain 0,87%, kayu 2,42%, kaca 0,9%, diaper 5,50%, logam 0,6% dan lain-lain 0,75%. Pewadahan sampah direncanakan individual dengan dibagi dua yaitu organik dan anorganik. Wadah sampah perumahan memiliki volume sebesar 30 L, musala 20 L, masjid 40 L, kantor 40 L dan sekolah dibagi menjadi empat dengan masing-masing 30 L. Pengumpulan sampah digunakan sistem individual tidak langsung dengan periodisasi tiga hari sekali dan ritasi 3 kali/hari. TPS 3R direncanakan memiliki ruang pemilahan, penampungan sampah anorganik, pencacahan, pengolahan sampah organik, kontainer residu, ruang pengelola, dan toilet dengan rencana anggaran biaya Rp433.775.651,00., The problem of solid waste occurs in Bulumanis Kidul Village so that the village government organizes waste management, but it is still not running effectively. This study aims to plan a waste management system from source to TPS 3R. The research uses quantitative methods. The results of the measurement of waste generation are 2,25 L/person.day with a composition based on mass including 55,49% organic waste, 9,77% paper, 19,50% plastic, 4,20% plastic bottles, 0,87% cloth, wood 2,42%, glass 0,89%, diaper 5,50%, metal 0,6% and others 0,75%. The waste container is planned individually and divided into two, namely organic and inorganic. Residential waste containers have a volume of 30 L, prayer rooms 20 L, mosques 40 L, offices 40 L and schools are divided into four with 30 L each. Waste collection is used an indirect individual system with a periodization of once every three days and recitation 3 times/day. TPS 3R is planned to have a sorting room, storage of inorganic waste, enumeration, processing of organic waste, residue containers, management room, and toilets with a planned budget of 433.775.651,00 IDR.

Judul: Pengaruh Cekaman Suhu terhadap Penyakit Koi Herpes Virus (KHV) pada Ikan Koi (Cyprinus carpio koi)
Abstrak: Koi fish are susceptible to Koi Herpes Virus Disease (KHVD). The disease is caused by the Koi herpesvirus, and mortality rate up to 80-95% within 2 weeks after infection. Koi herpesvirus is included in the virus that is hexagonal with a diameter of 100 nm. This study aims to determine the effect of temperature stress on the ability of Koi herpesvirus infects KHV free Koi fish and know the nature of transmission. Isolation and identification of Koi herpesvirus originate from the gills of Koi fish organs by the method of polymerase chain reaction (PCR) using PCR-KIT IQ2000TM. In this research, there were 8 fish groups of research, including the 6 fish group of test fish and two control test. The fish were injected with a virus suspension 10% as much as Koi herpesvirus 0.1 ml in intra peritoneal. For 14 days, seven of the first group as a fish's treatment of extreme temperatures at night 18-19 0C and 30-31 0C during the day. The 8th group of fish without control treatment temperature extremes. In a sequence group, the number of fish that were positive of KHVD were 5/5, 7/10, 5/5, 8/10, 0/5, 0/10, 4/5 and 0/5. KHV isolates with codes D143, D144 and M628 extremely virulent KHV isolates and not in the code D139. Stressed fish more susceptible to KHVinfection and KHV-infected fish easily transmit the koi herpesvirus in healthy fish or cohabitation by contamination of water in the aquarium and / or direct contact.
