Judul: Growth and Yield Model of Maize Intercropped with Cassava
Abstrak: This research consist of crop modeling that involves field experiment to construct a model of growth and yield of mize intercropped with cassava. The objective of the field experiment was to understand the process mechanism of competition between maize and cassava, to generate the parameters of piat growth md development and their values, and to validate the model. Field experiment of growing maize (Arjuna, Pioneer 4, and Cargill 9 in various planting densities) and assan (Adim 1) was conducted for monoculture and intercropped plants. Intercropped cassava increased intraspesific competition of maize. Yield of maize decsreased at about 3 to 14 %. Maize also reduced growth and yield of cassava. Taller. canopy of later maize variety and higher density caused heavier competition for 8 cassava. At highest dens@ of maize ((80 000 plants ha-'). intemmppcd with Arjuna, Pioner 4, and Cargill 9 decreased yield of cassava tuber of about 40.6%, 43.0°/0, dan I 64.3% respectively. However, the intercropping still gave a better land productivity, where land equivalent ratio (LER) was larger than 1.0. The LER of intercropping with Arjuna, Pioneer 4, and Cargill 9 were 1.5 1, 1.73, and 149, respectively. Model being constructed can be use to simulate growth and yield of maize and cassava in intercropping system, where the light dan soil moisture are the limiting factors. Validation of the mdel for total and grain or tuber dry weight variables result in 95% of variables are not significantly different with the observed values from the field experiment. However, using all variables, 80% of the model outputs are not significantiy different with the observed values. Those prove that the model has been able to describe the behaviour of growth and yield of both crops in the intercropping system and therefore, it can be applied for the purposse of prediction. The model still needs to be validatied for different time of planting, planting arrangement, and densities, plant growth factors for both crops, for wider application of the model.

Judul: Morphological and physiological responses of cowpea (Vigna unguiculata L) to intercropping with cassava (Manihot esculanta Crantz)
Abstrak: Cassava is one of the most important commodities in the world, as a source of food needed by the community because it contains many nutrients such as carbohydrates, protein, fat, calcium and magnesium. Cassava is a long-lived crop with slow growth, so the selection of intercrops in the form of legumes with short harvest days is needed. Cowpea is a type of legume that is widely developed because it contains high protein. Planting two crops with intercropping system can be done by adjusting the planting distance. The purpose of this research was to study the morphological and physiological responses of growth and yield of cassava variety "Mangu" in intercropping system of several cowpea varieties "Albina and Uno", and to study the growth and production of 2 cowpea varieties in intercropping system. The research was conducted from January to June 2023 at IPB Experimental Farm, Sawahbaru, Dramaga, Bogor. The research used a randomized complete block design with a single factor, namely the intercropping system pattern 1:2 is 1 row of cassava with 2 rows of cowpea, and 1:3 is 1 row of cassava with 3 rows of cowpea, consisting of Mangu and Uno 1:2, Mangu and Uno 1:3, Mangu and Albina 1:2, Mangu and Albina 1:3. Mangu monoculture. Uno monoculture. Albina monoculture with 4 replications and there were 28 experimental units. The results showed that P3 planting system gave the highest yield in crown height at 1,5,6 MAP, the highest canopy diameter at 4 MAP, tuber production, and 100-seed weight of cowpea. P4 gave the highest results in stem diameter, number of leaves, starch content, number of pods, pod dry weight, and seed dry weight at 9 MAP. The highest LER in this intercropping was found in 1:3 ubi kayu (Mangu) + Kacang tunggak (Uno), dan 1:2 ubi kayu (Mangu) + Kacang tunggak (Uno). The intercropping system suppressed weed growth at 2 BST along with the development of a wide canopy of cassava and cowpea plants that covered the soil surface., Cassava is one of the most important commodities in the world, as a source of food needed by the community because it contains many nutrients such as carbohydrates, protein, fat, calcium and magnesium.

Judul: Distemper Pada Anjing
Abstrak: Distemper merupakan penyakit infeksius pada bimbingan anjing yang menduduki tempet teratas dan penyakit ini tersebar di seluruh bagian dunia dimana terdapat anjing-anjing yang dipelihara, terutama pada anjing-anjing muda di kota-kota besar, pada kelompok-kelompok anjing atau pada situasi lain dimana banyak terdapat kontak antara anjing. Penyakit ini disebabkan oleh virus yang termasuk dalam famili Paramyxoviridae dan genus Morbilivirus. Infeksi virus ini sering disertai oleh infeksi sekunder oleh kuman Staphylococcus, streptococcus, Brucella bronchiseptica dan kuman Salmonella, inilah yang kadang-kadang sebagai penyebab kematian.
