Judul: Pemetaan Kemiringan Lereng berbasis Data Elevasi dan Analisis Hubungan Antara Kemiringan Lereng dengan Bentuklahan.
Abstrak: Slope is part of a landform determined by various factors which derived from endogenic and exogenic geomorphic processes. Topographic map is one of the most frecuently used data for slope steepnes mapping. Elevation data from satellite record such as Shuttle Radar Topography Mission (SRTM) or others recently also used to build topographic data. The aim of this research are (1) slope steepnes mapping based on Indonesian Topographical Map (Rupa Bumi Indonesia or RBI) scale 1:25.000 and SRTM, and (2) landform mapping and analysis for landform and slope relationship. The Cileungsi Watershed was selected for research area since it has various landforms. Mapping method was done visually for printed RBI, whereas for digital RBI and SRTM data were done digitally using geographic information system software (ArcGIS). Stratified random sampling approach has been used for field work upon interpertated landform and slope analysis maps. The result show that the widest slope class in Cileungsi watershed was quite different for each method. By visual method mapping (printed RBI), the widest slope steepnes was B-class (32%), as for digital RBI was A-class (41%), and for SRTM data was C class (35%). To know where the similar slope steepnes classes having the same spatial location (overlap), the overlay processes have been done between 3 slope steepnes maps i.e. derived from printed-RBI, digital- RBI, and digital-SRTM. By these operations, it reveal that the average of overlap area were 38% for visual-RBI vs. digital-RBI, 50% for digital-SRTM vs. digital- RBI, and 59% for digital-SRTM vs. visual-RBI. Thus, the latter comparasion indicated the better one in common results. Geomorphologically, Cileungsi watershed composed by 17 types of landforms where the denudational-claystone hills, was the widest landforms in study area (18,18%). In relation to the slope steepnes, the morphography of plains were generally characterized by A and B slope steepnes classes; for the river valley, such as floodplain & terraces were characterized by A-class, but for the river valley of upper slopes (in hilly and mountainous areas) were characterized by C and D-classes. For hills morfography, the characterized of dominant slope varies from B to D-classes and so did for mountains morfography. However the typical characteristic of hilly or mountainous landforms were the heavier of incision the greater of slope steepnes class.

Judul: Slope analysis based on the result of the drone mapping and Demnas SPR Mega Jaya and surrounding.
Abstrak: Peta kelerengan merupakan peta yang menunjukkan kondisi tingkat kemiringan suatu lahan. Tujuan dilaksanakannya penelitian ini adalah membandingkan hasil klasifikasi kelerengan dari hasil drone dengan DEMNAS, dan membuat peta topografi berdasarkan data DEM. Penelitian dilakukan di sekitar SPR Mega Jaya, Dusun Ngantru. Hasil citra drone yang telah dikoreksi dengan hasil GPS RTK diolah menggunakan agisoft photoscanner dan quick terrain modeler. Wilayah SPR Mega Jaya dan sekitarnya memiliki luas 119 ha dengan rata-rata kemiringan lereng 15-30%, sehingga tergolong dalam kelas kemiringan lereng agak curam. Hasil analisis kemiringan lereng DTM koreksi GCP dan hasil DTM non GCP pada kemiringan lereng 15-30% perbedaannya sebesar 11,4 ha, sedangkan antara DTM koreksi GCP dan DEMNAS perbedaannya 3,9 ha. Pada kelas kemiringan 30-45% perbedaan antara hasil analisis DTM koreksi GCP dan hasil DTM non GCP sebesar 5,9 ha, sedangkan antara DTM koreksi GCP dan DEMNAS 8,1 ha. Nilai DEMNAS dibandingkan data lapang lebih baik daripada DTM non GCP terhadap data lapang. Peta topografi di lokasi SPR Mega Jaya dibuat berdasarkan data DTM dengan koreksi GCP dengan elevasi maksimal 102 m dan minimal 72 m.

Judul: Pengaruh vaksin aktif dan inaktif terhadap kekebalan dalam pencegahan penyakit newcastle pada ayam
Abstrak: Penyakit Newcastle adalah penyakit yang bersifat infeksius dan kontagius yang menyerang unggas terutama ayam dan kalkun; menimbulkan kematian, penurunan produksi dan kwalitas telur sehingga menimbulkan kerugian ekonomi yang besar; disebabkan oleh paramyxovirus yang termasuk ke dalam golongan virus yang berinti asam ribonukleat. Virus penyebab penyakit ini terdiri atas beberapa galur yaitu velogenik, mesogenik dan lentogenik. Vaksinasi adalah salah satu cara untuk mencegah timbulnya penyakit dan kerugian yang ditimbulkannya. Vaksin terdiri atas vaksin aktif dan inaktif atau vaksin dalam emulsi minyak. Vaksinasi pada umur dini adalah cara yang paling baik dilakukan. Umur ayam yang tepat mulai dilaksanakan vaksinasi adalah pada umur 4 hari, karena pada saat ini titerantibodi asal induk sudah mulai turun dan kondisi ayam sudah mulai kuat untuk dilakukan vaksinasi jika melakukannya pada ayam umur sehari. ...
