Judul: Income of Candlenut Farmes and a Model for Estimating the Weight of Candlenuts (Aleurites moluccana) in Sigi Regency, Central Sulawesi
Abstrak: Kemiri merupakan hasil hutan bukan kayu yang bernilai ekonomi tinggi bagi masyarakat. Akan tetapi, penelitian mengenai hubungan antara dimensi pohon dan berat kemiri belum banyak dilakukan. Penelitian ini bertujuan menghitung rata rata pendapatan petani kemiri, menganalisis hubungan berat kemiri dengan dimensi pohon dan menyusun model penduga berat kemiri. Model disusun menggunakan regresi linier dan non linier. Hasil penelitian menunjukkan bahwa rata-rata pendapatan yang diperoleh petani sebesar Rp2.510.460,53/ha/bulan, variabel dengan keeratan hubungan tertinggi terhadap berat kemiri adalah umur dan lebar tajuk sedangkan model terbaik dalam menduga berat kemiri adalah model M3a dengan persamaan B = 2,070+0,004*T^2*U. Model tersebut dapat menjelaskan variasi berat kemiri sebanyak 41% dengan AIC 755,46, dan RMSE sebesar 13,02 kg/bulan. Selain itu, model tersebut telah memenuhi asumsi homoskedastisitas dan normalitas sisaan., Candlenut is non-timber forest product that have high economic value for the community. However, there has not been much research on the relationship between tree dimensions and candlenut weight. This study aims to calculate the average income of candlenut farmers, analyze the relationship between candlenut weight and tree dimensions and compile a model to estimate the weight of candlenut. The models were arranged using linear and non-linear regression. The results showed that the average income obtained by farmers was Rp2,510,460.53/ha/month, the variables with the highest relationship with the weight of the candlenut were age and width of the crown while the best model in estimating the weight of the candlenut was the M6 model with the equation B = 2,070+0,004*T^2*U. The model can explain the variation in candlenut of 41% with AIC of 755,46, and RMSE of 13,02 kg/month. In addition, the model has met the assumptions of residual homoscedasticity and normality

Judul: Tabel Berat Pohon Tegakan Akasia Mangium (Acacia mangium Willd) (Studi Kasus di IUPHHK-HA PT. Bumi Pratama Usaha Jaya Sumatera Selatan)
Abstrak: The availability of tools in a Comprehensive Forest Inventory Periodic activities (IHMB) are necessary to speed up the activities and minimize the errors that occur in the measurement. The purpose of this research is composing the tree weight table of Acacia mangium (Acacia mangium Willd) species in IUPHHKHA PT. Bumi Pratama Usaha Jaya. Results of the regression analysis were taken into three categories that can indicate good or bad for an equation is the coefficient of determination ( ), standard error (SE) and count. The model validation can be performed using the aggregation deviation test (SA), the average deviation (SR), the RMSE (Root Mean Square Error), the value of the bias and real difference test conducted with the chi-square test between the alleged weight with the weight of fact table. Based on the results obtained, the equation can be used to infer a tree weight with skin and without skin based on the diameter in IUPHHK-HA Acacia mangium plant area of PT. Bumi Pratama Usaha Jaya each have Bdk = 0,4799 D1,9109 equation for tree weight with skin and Btk = 0,2096 D2,0841 equation for tree weight without skin.

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.
