Judul: Deteksi Perubahan Tutupan Hutan dan Lahan Menggunakan Citra ALOS PALSAR Multiwaktu Resolusi 50 Meter di Provinsi Jambi Bagian Timur
Abstrak: Degradation and deforestation in Indonesia is a complex issue that needs to be addressed comprehensively and wisely. Within the period of 2000 - 2012, the national level rate of deforestation is estimated at about 832.126,9 ha / year, while in Jambi Province is approximately 76.522,7 ha/year. Now, the national level deforestation is generally estimated using medium-resolution satellite, such as Landsat, SPOT, ASTER, IRS etc with post-classification comparison approach. For Indonesia, which is located in the tropical region, the use of optical imagery is often constrained due to the high proportion of cloud cover and/or haze during the wet season, and smoke coverage during dry season. The availability of radar imagery such as ALOS PALSAR, JERS-1, Radarsat and ERS-1 that capable to record the earth in all weather conditions as well as capable to penetrate clouds and smoke/haze provide a new prospective in detecting forest and land cover changes. The availability of ALOS PALSAR imageries since 2006/2007 had been provided a good opportunity either for complementing or substituting the optical imagery, especially in the areas of high atmospheric disturbances. Based on the above, this research is aimed to evaluate the ability of 50-meters resolution of ALOS PALSAR imagery for detecting forest and land cover, as well as their changes in eastern part of Jambi Province between 2007 and 2009. The study site includes five regencies in Eastern Part of Jambi Province, namely Tanjung Jabung Barat, Tanjung Jabung Timur, Muaro Jambi, Jambi and Batanghari. Meanwhile, image processing and data analysis was carried out in the Physical Laboratory of Remote Sensing and Geographycal Information System, Laboratory of Forest Resource Inventory Faculty of Forestry IPB. The images used in this reasearch are ALOS PALSAR with HH, HV and synthetic band HH / HV bands recorded on 8 June to 30 November 2007 and from 13 June to 15 October 2009. The softwares used in this research are the Arcview GIS 3.2, ArcGIS 9.3, and Erdas Image 9.1. The classification method used consisted of qualitative and quantitative approaches. In qualitative approach, the classification was performed by visual interpretation on the basis of diagnostic elements of interpretation while in the quantitative approach, classification was done using the supervised classification. The research results show that the Kappa Accuracy of qualitative classification of ALOS PALSAR for 2007 and 2009 are 80% and 82% respectively, while the quantitative approach provides Kappa accuracy of 56% for 2007 and 59% for 2009. The study also found that the largest changes in land cover occured from barren land to plantation forest having area of about 16.866,4 ha. Within 2 years (2007 – 2009) period, the deforestation area is approximately 10.264,3 ha or approximately 5132.15 ha per year, where the largest deforestation occured from forest plantation to oil palm covering area of about 6.928,4 ha or 68% or about 34% per year. Besides, the largest degradation, i.e, from forest plantation to 5 barren land is about 10.195,7 ha or 87% ((or about 34% per year.) By considering the spatial patterns of forest and land cover change between 2007 and 2009, the deforestation and land degradation

Judul: Aplikasi Citra ALOS PALSAR Multiwaktu Resolusi 50 m dalam Identifikasi Tutupan Lahan di Provinsi Lampung
Abstrak: Land cover change is a state of land in which changes occured through passing time due to human activities (Lillesand & Kiefer 1990). Land cover change has different change dynamics between one land to another, that it requires continuous monitoring to observe those changes. The use of remote sensing technology had become a very important part in the mapping of land-closure and land-use, as well as land cover changes associated with the study of vegetation, crops and soil of the biosphere. Cloud cover had posed obstacles in the use of LANDSAT and SPOT optical imagery in Indonesia. Active remote sensing systems (radar) which has the ability to one way technology to overcome the obstacles. In 2006, the Japanese government launched a satellite named ALOS (Advanced Land Observing Sattelite) that carries the radar sensor (JICA 2011). One of the sensor types is PALSAR (Phased Array Type L-band Shynthetic Aperture Radar) operating each year, so it can be used for monitoring land cover change. This study aimed to analyze land cover change and identity the dynamics of changes in one year periods of 2007-2008 and 2008-2009, as well as the two-year period of 2007-2009 using multitime ALOS PALSAR image with spatial resolution of 50 m in Lampung province. Field research was conducted on August 10th until 18th 2012 in Lampung province. The method of this research is visual analysis of land cover change combining RGB HH-HV-HH/HV 1:50.000 scale and matrix of land cover change. The results of the visual analysis of ALOS PALSAR imagery in 50 m resolution showed 17 land cover classes namely water, airport, dry land forest, swamp forest, plantation forest, multiplants field, pineapple field, sugarcane field, open land, savanna, rubber wood plantation, oil palm plantation, settlements, dry land farming, paddy fields, scrub / shrub wetlands, and ponds. The pattern of changes observed in Lampung province was a drastic change in which open land changed into a vegetated land or otherwise vegetated land changed into open land. Based on the type of land cover, the change of land cover in Lampung both in one year and two years periods had the similar kind of change, which was transformation from open land into sugarcane field, open land into pineapples field, sugarcane field into open land, pineapple field into open land, and rubber wood plantation into open land.

Judul: Akupuntur pada Kasus Konstipasi Kucing Persia.
Abstrak: Seekor kucing betina ras persia bernama Lucy telah mengalami konstipasi yang berulang kali sehingga terjadi kronis. Terapi akupuntur digunakan sebagai pengobatan alternatif dalam studi kasus ini dengan tujuan meningkatkan motilitas gastrointestinal. Studi kasus ini bertujuan untuk mengetahui efek akupuntur pada kasus konstipasi di kucing Lucy. Terapi akupuntur dilakukan dengan menggunakan dry neddle pada titik BL-21, BL-25, CV-4, CV-6, CV-12, GV-1, ST-25, dan ST-36. Terapi dilaksanakan selama 15 menit setiap terapi dan dilakukan seminggu 3 kali sampai terjadi perkembangan persembuhan. Berdasarkan hasil pemeriksaan fisik dan pemeriksaan penunjang radiografi, terdapat penumpukan feses yang banyak dari kolon hingga rektum. Kucing dapat defekasi dengan lancar setelah terapi ke-3 dan kondisi kucing yang awalnya buruk semakin membaik.
