Judul: Reduction of Irrigation and Pruning leaves for Solar Radiation Use Efficiency of Maize in Dryland
Abstrak: In Indonesia, maize (Zea Mays L.) is cultivated mostly on the dry land, where water is the main limiting factor for production. Thus, it is necessary to develop the efficient cultivation techniques in terms of water use. The objective of this study was to evaluate the effect of the reduction of irrigation and pruning leaves below the cob on the ability of plants to intercept solar radiation for growth, and for radiation and water use efficiency (RUE and WUE) and maize productivity. Irrigation treatments for crop water requirement is conducted on 3 levels, namely 100% fulfilment of the total water requirement for one growing season (DI 100%), the reduction of 20 and 40% of the total crop water requirement (DI 80% and DI 60%). While pruning is conducted by the time plants have entered the generative phase with 3 level of treatments, i.e. without pruning (P0) as a control, and prunning of 3 and 6 leaves below cob (P3 and P6). Radiation use efficiency (RUE) treatments DI 80% (3.2 g MJ-1) was not significantly different from treatment DI 100% (3.1 g M-1), is greater than the RUE treatments DI 60% (2.6 g MJ-1). RUE P0 treatment (3.1 g MJ-1) was not significantly different from treatment RUE P1 (3.0 g MJ-1), both higher than the P6 RUE treatment (2.7 g MJ-1). These results indicate that the reduction of 40% of the total crop water requirement or trimming 6 below cob leaf can decrease the RUE. Plant productivity on DI 100% treatment (7.0 ton ha-1) was the highest. Plant productivity on DI 80% treatment (6.6 ton ha-1) was not significantly different from DI 60% and DI 100% (6.2 ton ha-1). WUE treatment DI 60% (0.74 kg m-3) significantly higher than WUE treatment DI 80% (0.59 kg m-3) and WUE treatment DI 100% (0.50 kg m-3). The results showed that the reduction of irrigation up to 40%, could reduce the crop productivity because of crop water requirements are not fulfilled optimally. Nonetheless, the reduction of irrigation can be applied as an efficient cultivation techniques in terms of water use so that the sustainable production and conservation of water resources can be achieved.

Abstrak: The research of the influence of dose management on water irrigation and Corn’s below leaf prune to the Lamuru productivity in the dry climate area has been done. This research was conducted on the Naibonat Expriment Farm, East Kupang Sub District, Kupang, Nusa Tenggara Timur, from June to October 2011. The area has been used is 72 m x 32 m using Split Plot Design Methods. This research was using two treatments; the first treatment is conducted on the main plot with water irrigation dose given 100%, 80%, 60%, and the dose control is appropriate with the Farmer’s custom. The second is conducted to the Corn’s leaf at the generative phase through with and without leaf pruning on the determined sub main plot. The result has showed that water irrigation dose treatment between 80% and 60% is significant to the Corn’s productivity that is 7.7 ton/ha and 5.3 ton/ha, but not significant to the control (7.0 ton/ha). On the other hand, the treatment with and without leaf prune are not significant to the growth component because the prune is conducted at the generative phase. The Anova test result has not showed the significance between the treatment of with and without leaf prune to the Corn’s productivity. The 80% dose of water irrigation could thrift the water until 842 m3 or 20% per one planting season in one hectare. Meanwhile, the farmer’s custom has lavished of the water until 2.105 m3 or 50% per one planting season in one hectare. Based on the analysis, the optimizing of water irrigation interval is seven times along one planting period which is more efficient than Farmer’s used with fourteen times along one planting period.

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.
