Abstrak: The land is a mixture of physical and natural environment that includes its climate, ground, relief, and hydrology. The mixture of soil has consequences of its land use. On the other hand, the success of agriculture and agro-industry is influenced by the success of its agriculture cultivation. This research intends to build an expert system that can be used to determine evaluation of crop land, in particular, for patchouli crop. The Expert System of Patchouli Land Suitability is aimed to provide information on land characteristics that are suitable for patchouli . We make use of the expertise of Dr. Ir. Rosihan Rosman, M.Sc to provide knowledge to the expert system developed. The processing input for the expert system comes in two formats, i.e., fuzzy inputs and non-fuzzy inputs. Fuzzy Inference System (FIS) with Mamdani method was first used as the inference method for the fuzzy output followed by an application of non-fuzzy inputs. The expert system provides three categories of evaluation, i.e., very suitable, suitable, and unsuitable land cultivation for patchouli. Each category has specific land characteristics tied with the evaluation. Furthermore, the expert system was assessed on sixteen different lands to verify system accuracy. Assessment results present 75% accuracy when verified using human expert assessment.

Abstrak: Patchouli is a producer of essential oils that has a higher export value. The selection of good and excellent patchouli plant seed is necessary in order to produce good quality of essential oils. This research assesses superiority of patchouli plant seeds using three known superior varieties as a reference. The varieties are tapak tuan, lhokseumawe, and sidikalang variety which are derived from the aceh varieties. To this purpose, we develop an expert system which is aimed to assist nilam developers in selecting good seeds and patchouli superior plants. During the process, morphological characteristics of patchouli plant varieties result in about 108 rules. Further examination determined only 27 rules are applicable to determine its superiority while the remaining rules are inapplicable. The expert system was assessed using 30 patchouli plant seeds to verify system correctness. Note that 30 plant seeds being assessed was known as superior variety prior to its assessment. Assessment results recognized that 93% of the plant seed is categorized as superior type. Additional assessment using 50 unknown patchouli variety was also carried out. The results of the assessment by the expert system concluded that 84% of the patchouli plants were determined as superior patchouli plants, and results from the expert assessment concluded that 86% are superior patchouli plants. In conclusion, the expert system developed is able to determine patchouli plant seed superiority based on its morphology with relatively good accuracy.

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.
