Judul: Identifikasi Perubahan Tutupan Lahan Menggunakan Landsat 7 dan Landsat 8 (Studi Kasus di Asosiasi Petani Hutan Rakyat Wonosobo)
Abstrak: Community forest is a forest that grow on public land. Community forest is growing fast especially in Java. Land cover change is also increasing along with comunity forest growth. Land cover change in APHR Wonosobo can be identified using remote sensing. The aim of this research are to identify and calculate the land cover change in APHR Wonosobo from 2003 to 2014. The method used in this research is visual interpretation method. The land covers of the study area were classified into pine forest, settlement, water, dryland farming, rice field, shrub-bush, bare land and mixed vegetation. The land cover change in a positive direction is 449.24 ha (31.5%) and in a negative direction is 122.18 ha (8.6%).

Judul: Identifikasi Perubahan Tutupan Lahan Menggunakan Citra Landsat Multiwaktu dan Teknologi Sistem Informasi Geografis (SIG) di IUPHHK-HA PT. Austral Byna Kalimantan Tengah
Abstrak: The utilization of forest by Forest Concessions (HPH) or now known as The Forest Utilization License Timber-Forest Nature (IUPHHK-HA) brings many benefits but it also brings a downside for the Indonesian forestry. This activity has increased economic and regional development, but also lead to greater rates of deforestation and forest degradation as well. In general degradation that occurs in production forests result in damage or reduction of productive forest area to total forest area that will affect productivity. The negative impact of deforestation and degradation can be minimized through the efforts of a fast and efficient monitoring using remote sensing. Digital imagery or remote sensing data is one of the data to analyze the surface of the earth. Ministry of Forestry using Landsat imagery as one tool in monitoring the condition of Indonesia's forests. Landsat multi-time combined with Geographic Information Systems (GIS) facilitate the monitoring process. Both long-term monitoring and short-term monitoring can be controlled so that the rate of deforestation. This study aims to identify land cover classes as well as changes in the PT. Austral Byna in 1997, 2005 and 2012, and calculate the rate of degradation and reforestation arising from the use of forests in the periode of observations. The experiment was conducted in two phases, field phase in April-May 2012 in PT. Austral Byna, and image processing in June to November 2012 in the Laboratory of Remote Sensing and GIS Department of Forest Management Fahutan IPB. The data used are Landsat TM and ETM+ 30 m resolution coverage in 1997, 2005 and 2012 as well as other supporting digital maps. The tools used in the form of PC with the software ArcView 3.2, ArcGIS 9.1, Erdas 9.1, GPS, Camera and stationery. The result showed that successfully classified land cover both digital and visual consists of forests, fields, bushes, farm, vacant land and clouds. Degradation of the highest in 1997, 2005 and 2012 occurred in the class turned into a forest shrubs. While reforestation occurred in the highest class of the field and forest shrubs that turned into a forest.

Judul: Parasitemia Dan Kadar Zink Dalam Darah Meneit Setelah Diinfeksi Trypanosoma Evam'; Serta Pemberian Nand Partikel Logam Zink
Abstrak: Penelitian ini menggunakan nano logam Zn terserap tubuh yang memiliki tujuan untuk menguji potensi logam Zn tersebut dan diharapkan dapat dijadikan sebagai antitrypanosoma. Uji ill vivo menggunakan 50 ekor meneit strain DDY dan dibagi menjadi lima kelompok, yaitu: KN (meneit dengan perlakuan normal), KP (meneit yang diinfeksi T evans; namun tidak diberikan nano logam 20), Oasis I (meneil diinfeksi T. evans; dengan pemberian nano logam Zn dosis 175 mgIKg), Dasis U (meneil diinfeksi T evans; dengan pemberian nano logarn Zn dosis 350 mgIKg), dan Oosis rn (mencit diinfeksi 7: evans; dengan pemberian nano logam Zn dosis 700 mgIKg). Parameter yang diamati pada penelitian ini adalah parasitemia, nilai pev, kadar zink dalam darah, dan tingkat kematian mencit. Pada hari ke nol , empat dan tujuh dilakukan pemeriksaan darah untuk mengetahui jumlah parasit dalam darah (parasitemia), nilai pev dan kadar zink dalam darah. Kemudian han ke nol hingga ke tujuh dilakukan juga pengamatan tingkat kematian mencit. Hasil penelitian menunjukkan bahwa pemberian nano logam Zn tidak marnpu menurunkan tingkat parasitemia. Semakin tinggi konsentrasi Zn yang diberikan, mengakibatkan jumlah parasit cenderung semakin banyak. Ni lai pev teruS menurun secara nyata (P<O.05). Kadar zink dalam darah dengan perlakuan Oosis I meningkat pada hari ke tujuh hingga 12.53 ppm, sedangkan Oosis II terjadi penurunan zink hingga hari ke tujuh setelah infeksi 7iypal1osoma, dan Dosis m terjadi peningkatan zink pada hari ke empat lalu mati pada hari ke tujuh.
