Judul: Bentuk Penggunaan dan Produktifitas Lahan Sistem Dusung (Studi Kasus di Kecamatan Leihitu, Kabupaten Maluku Tengah)
Abstrak: The practice of agroforestry system in Maluku had been occurring for many generations since long time ago, and the people usually called this system as dusung. Agroforestry dusung was a heritage from the ancestors to their descendants, and comprise wood tree, fruits, sago, palm and medicinal plants. This research was conducted to identify the type of land use in dusung system, rearn the land productivity in dusung system, study and to analyze the forms of dusung system for land conservation at Wakal village and Hatu village, Leihitu district, central Maluku, Ambon Island. There were three types of land uses on dusung system, namely farm system, mixed planting system and monoculture planting system. Of these three land uses, the highest production was in mixed planting system on Wakal and Hatu villages which were (Rp 9.716.000,- /ha/year and Rp 11.468.000,- /ha/year). Production in monoculture system in the two villages were respectively (Rp 5.050.000,- /ha/year and Rp 6.785.000,- /ha/year), whereas those of farm system were (Rp 3.466.924,- /ha/year and Rp 2.394.804,- /ha/year). Erosion on land use in dusung system varied according to the type of land uses and land slope. Erosion index ranged within 0 - 1, while degree of erosion was categorized as ranging from low to medium. Erosion in Wakal Village, for farm system was 53.83 ton/ha/year which was greater than ETot 48 ton/ha/year. In monoculture planting system erosion reach of 72.30 ton/ha/year, which was greather than ETot 45 ton/ha/year. On the other hand, farm system in Hatu Village had caused erosion of 49.5 ton/ha/year greater than ETot 30/ha/year. Mixed planting system in Wakal and Hatu had erosion of respectively 30.68 to /ha/year and 12.14 ton/ha/year, which were below ETot 45 ton/ha/year and 43.2 ton/ha/year.

Judul: Perencanaan Penggunaan Laban untuk Pembangunan Pertanian Berkelanjutan di DAS Lahumbuti Sulawesi Tenggara
Abstrak: Land use which is not compatible with land capability and lack of awareness to apply soil conservation measures, are the causes of increasing erosion and decreasing soil productivity which ultimately lead to low income of the farmers. Therefore, there is a necessity for proper land use management plan, particularly in the Lahumbuti catchment for achieving sustainable agricultural development. The research that has been conducted in Lahumbuti catchment. has the objectives of evaluating land use and land capability, and also le::rrning the agrotechnolo-g-; applied in the Lahumbuti catchment. Beside that, the study was also aimed at designing alternative for land use management plan which is compatible with land capability to achieve sustainable watershed management at Lahumbuti catchment. Method used in this research was survey method that comprised collection of primary data and secondary data. Primary data includes (a) physical condition of the land (steep slope and length of slope, permeability, effective soil depth, drainage, texture, stucture and content of the soil organic matter) and (b) socio-economic condition (demography, production facility, cost, farmers income and agrotechnology applied in the study site), evaluation of suitability betwen land use and land capability using Klingebiel and Montgomery criteria, erosion estimate using USLE method, calculation of Etol using Hammer method (1981 and evaluation of living standard appropriateness using Sajogyo and P. Sajogyo ( 1990 ). Secondary data are in the form of daily rainfall data, facts in the district, topographic map and soil map. Research result showed that generally land use in Lahumbuti catchment are accordance with their land capability, although there were several farming activities that were conducted on steep slope. Planting pattern and agrotechnology adopted by farmer were still traditional. Result of erosion prediction at intensive obsevation site indicates that the occuring erosion (13,03-262,10 tonnes/ha/year) were greater than the soil loss tolerable (8,65-48,% tonnes/ha/year), resulting in decline of land productivity and farmers low income (Rp. 2.822.650,- - Rp. 8.033.100,- HH/ha/year). Therefore, there is need for change in cropping pattern and agrotechnology, accompanied with soil conservation measures so that erosion could be reduced to a minimum level which is smaller than the tolerable level. Pursuant to equality of land capability class and types of cultivated crop betwen the intensive observation sites and the land units at the whole of Lahumbuti catchment, land use recomendation in the catchment is that at land class I (21.870 ha) and land class II (1213,5 ha) the suitable land used are mixed garden and dry land, there would be inter cropping (tumpangsari, tampang si1>ip) and multiple cropping, accompanied by mulch and construction of bund terrace. Forest and shrubland could be converted to mixed garden and dry land or agroforestry system. Land class III (11.624,1 ha) and class IV(28.373,7 ha) are

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.
