Judul: Spatial Modelling for Distribution and Habitat Suitability of Invasive Alien Species Kirinyuh (Austroeupatorium inulifolium (Kunth) R. M. King & H. Rob) in Mandalawangi Resort Gunung Gede Pangrango National Park.
Abstrak: The existence of invasive alien species influenced the ecosystem, and at the same time could not be controlled. This could cause disturbance of ecosystem function and also declined forest value, ecologically and economically. Some national parks have been facing serious threat caused by invasive alien species and 37 species were identified in Gunung Gede Pangrango National Park (GGPNP). It is important to carry out this research in GGPNP since the information on the distribution and habitat suitability for invasive alien species, especially for kirinyuh, is still limited. The objectives of this research were to determine the distribution and habitat suitability model for kirinyuh and the suitability degree of GGPNP as habitat for kirinyuh. Binary Logistic Regression Analysis and Principal Component Analysis were used to predict probability of habitat suitability for kirinyuh. Fifty percent of recorded data was used to build a predictive model and the rest was used to validate the model. Habitat requirements were analyzed and quantified from digital topographic maps, ASTER DEM and Landsat 7 ETM+. The result showed that predictive model of habitat suitability for kirinyuh was affected by elevation, NDMI, NDVI, distance to farmland and distance to trail. The result suggested Principal Component Analysis was more appropriate for spatial modelling than Binary Logistic Regression.

Judul: Sifat fisik dan kandungan Fe Meatloaf yang menggunakan tepung daging sapi sebagai bahan baku
Abstrak: Meatlof merupakan produk yang serupa dengan sosis. Hal yang membedakannya ialah pada meatloaf dilakukan pengisian ke dalam loyang dan dipanggang pada suhu 180 °C selama 30 menit. Meatloaf biasanya terbuat dari daging segar, yang memiliki nilai gizi yang tinggi, baik dari segi nilai biologis, kecernaannya maupun kelengkapan asam aminonya dibandingkan bahan nabati, namun masih dinilai sebagai bahan pangan yang sifatnya perishable (mudah rusak). Pembuatan tepung daging melalui proses freeze drying bertujuan untuk meningkatkan umur simpan dan memudahkan pemanfaatannya dalam pembuatan produk olahan. Penggunaan tepung daging sapi dalam pembuatan meat loaf daging sapi diharapkan menjadi alternatif dalam pemenuhan kebutuhan protein hewani dan menjadi langkah awal untuk inovasi teknologi pembuatan meatloaf daging sapi yang praktis.
