Judul: Pengembangan Modul Visualisasi Perubahan Stok Karbon pada Perangkat Lunak REDD Abacus
Abstrak: Carbon emission reduction from forest deforestation and degradation becomes a problem focus in the attempt to cope with climate changes. Deforestation was estimated to release carbon in the order of 1-2 billion tons per year in 1990, about 15-25% of greenhouse effect gases in the whole world. From those data, it is urgently needed to monitor carbon stock changes. Visualization is a common technique used to monitor the condition. REDD Abacus, developed by ICRAF, provides carbon stock changes information, but it lacks visualization. This research presents a development of carbon stock changes visualization module to supplement the REDD Abacus. This module can visualize carbon stock changes in a region in one period of changes. It is developed with uDig platform. The module can generate visualization map in 2 formats, i.e., vector and raster. Processing with pixel calculation is executed when the user needs the map result in raster format, taking 3-4 seconds. Processing with spatial query is executed when the user needs the map result in vector format, taking 10-15 minutes.

Judul: Model dinamika perubahan hutan dan lahan dan skenario perdagangan karbon di Provinsi Jambi
Abstrak: The rate of deforestation and forest degradation in the sector of LULUCF (Land Use, Land Use Change and Forestry) continues to increase along with the increase in land and forest products. In 2009, the release of forest area in Jambi province reached 77,216 hectares, land use 344,305 hectares, and forest area exchange 80,861 hectares. The importance of non-forestry sector development has resulted in the decrease in forested areas (deforestation) and the cover of forested areas (forest degradation). The rate of deforestation in Jambi reached 165,665 hectares, in which 39.75% occurred in West Tanjung Jabung Regency. The use of forest area for non-forestry sector development is set out in the national development policy. The policy changes bring about the changes in the interaction of forest stakeholders to the forest areas. To reduce the rates of deforestation and forest degradation, the government has used REDD + scheme. One scenario in REDD+ scheme is with a moratorium on the use of forest areas. Projected deforestation and forest degradation can be done through dynamic system when a moratorium on forest area utilization is conducted on the intensity of 30%, 50% and 70% out of the forest area use permit in BAU. The implementation of a moratorium can decrease deforestation and degradation about 9% -43%. Implementation of a moratorium of forest area use permit in REDD+ scheme does not provide a very large income. The income of REDD + is only about 0.76 to 1.35 billion USD in every 5-year contract, much lower compared to BAU income of Jambi which reaches USD 678,912 per year and it may threaten 1,290,854 employment opportunities for people.

Judul: Trichomonosis salah satu penyebab infertilitas pada sapi betina
Abstrak: Trichomonosis adalah salah satu jenis penyakit kelamin menular pada sapi yang bercirikan kemajiran, keguguran dini dan pyometra, dan disebabkan oleh protozoa, Tritrichomonas foetus, yang ditularkan pada sapi-sapi betina oleh perkawinan pejantan yang terinfeksi. Organisme berflagela dengan bentuk tubuh seperti buah pear, berukuran panjang 10 sampai 25 mikron dan lebar 3 sampai 15 mikron itu berkembang biak secara longitudinal binary fission, dan pada preparat segar bergerak memutar, tersendat-sendat seperti spiral dan tidak menentu. T. foetus hanya ditemukan pada saluran kelamin yaitu vagina, cervix, uterus dan isi uterus sapi betina. Segera sesudah mati oleh pengeringan, antiseptika, panas berlebihan dan kondisi negatif lainnya, T. foetus kehilangan bentuk sehingga sulit dibedakan dari reruntuhan sel. Gejala trichomonosis yang paling umum adalah infertilitas atau ketidaksuburan yang ditandai oleh meningkatnya angka Service per Conception (S/C) dan jarak waktu yang lama antara partus dan estrus pertama postpartum. Angka S/C dapat meningkat dari 1,82 pada keadaan normal menjadi rata-rata 5,15 pada trichomonosis. T. foetus menyebabkan perbarahan pada endometrium, selaput lendir cervix dan vagina, dan mempengaruhi perkembangan embrio dan fetus sehingga dapat menyebabkan infertilitas. Terjadinya infertilitas tersebut ialah karena pencegahan implantasi dari ovum terbuahi yang berada dalam uterus yang telah dikolonisasi T. foetus. Pada infertilitas interval antar berahi menjadi panjang karena kematian embrio dini yang sering terjadi pada 15 sampai 80 hari masa kebuntingan. Pada kematian embrio dini, embrio tersebut mengalami maserasi dan diabsorbsi oleh uterus atau dikeluarkan tanpa diketahui. ...
