Judul: Linkage Characteristics of Land with Palm Oil Productivity as a Basic for Land Evaluation
Abstrak: Variability of oil palm productivities are various due to land properties and characteristics. These require informations of soil fertility in every soil types. These informations are able to drive land management and technical culture of oil palm. The informations can be obtained through land evaluation. This study aims to assess the potential land suitability for oil palm. Field surveys and observations carried out at oil palm plantation business unit Bentayan, PT Perkebunan Nusantara VII (Persero), South Sumatra. Chemical analysis conducted at the Laboratory soil of Chemistry and Fertility, Department of Soil Science and Land Resources, Faculty of Agriculture, Bogor Agricultural University. Land classes were determined on land characteristics i.e. based on degree at the limiting factor classifield as actual land suitability classification. In this case, land characteristics were matching with oil palm land suitability criteria. Land suitability for production based was also measured to obtain potential land suitability classification. The results show that land classes at oil palm based on land characteristics obtained covering S2f, S2wf, S3w, S3wf, and N1w. Actual land suitability at S3w increased to S2 potential class at 5, 7 and 9 years palm oil. Actual land suitability at N1w increased to S3 potential class at 7 years palm oil, and S2wf increased to S1 at 5 years palm oil These increases were caused improvement of the limiting factor i.e. improvement of drainage, application of organic materials, soil ameliorant, and fertilizers.

Judul: Identifikasi Kenampakan Kelapa Sawit dan Produktivitasnya Melalui Sistem Informasi Geografis (Studi Kasus PT. Perkebunan Nusantara VIII Cimulang, Bogor)
Abstrak: Oil palm (Elaeis guineensis Jack.) is an important commodity in Indonesia and still has a high development prospects. In 2011 there was a positive development at the national oil palm industry especially from the increase in production, export, and price developments. The CPO production is expected in 2011 around 23.5 million ton, with exports at 16.5 million ton, while the average price of CPO in 2011 is estimated at U.S. $ 1125 per ton. In 2011 Malaysia had reached total 5 million hectares of oil palm plantations. Malaysian oil palm production in 2011 increased 11.3% to 18.91 million tons from 16.99 million tons in 2010 (GAPKI, 2012). The efforts to improve oil palm productivity relate to many factors, such as land characteristics and its management. The lack of effectiveness management of oil palm plantations can decrease productivity of oil palm. Technologi spatial information like Remote Sensing and GIS is a current technology that may handle spatial data. These technologies can help business management such as object identification and pattern analysis of agricultural system. Identification oil palm can be conducted using a particular image, while GIS may help to analyse its pattern, so that this research’s aim were to recognise oil palm and its productivy regarding to its management. PT. Perkebunan Nusantara VIII Cimulang is one of Indonesia State Owned Enterprise engaged in management of oil palm. The results of image interpretation, ALOS AVNIR-2 showed that the PT. Perkebunan Nusantara VIII Cimulang had a variety of ages oil palm plant, that reflected from the green color and texture differences in the appearance of image. The spatial analysis result showed the highest productivity was found on the flat areas, while the lowest productivity was found in undulating region. The highest productivity oil palm was located on (Aquic) Humitropept while the lowest productivity of land was located at Typic Haplohumult. The highest productivity of oil palm was occurred at a location with fertilise dosage of 2005, while the lowest productivity was occurred at a location with fertilize dosage of 2004. From the statatistic of variance, the variatian of fertilization rate did not significantly affect the productivity of oil palm. So far, implementing of high rate of fertilization would consequently lead to high costs, but this did not give maximum profit for oil palm productivity as there was no significantly different production between the high rate and low rate of fertilization.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
