Judul: Potensi Parameter Keluaran RAOB (Rawinsonde Observation Programs) sebagai Indikator Kunci dalam Analisis Curah Hujan
Abstrak: One of the weather elements that strongly influences human activity is rainfall. RAOB (Rawinsonde Observation Programs) is a tool in analyzing events related to rainfall. This study utilizes observational rainfall data over a period of one year, and radiosonde data series of 3 hours and 6 hours before the occurrence of rain obtained from NOAA (National Oceanic and Atmospheric Administration). This study aims to understand the technique of determining rainfall indicators and analyzed the output of RAOB program to determine RAOB index that affect the most to rainfall. It also aims to further screen the parameters into three main categories of rainfall events, namely, heavy, and light. This study reveals that Cap Strength, Vorticity Generation Parameter, and Total CAPE parameters collected 6 hours prior to the occurrence of heavy rainfall are potentially good predictors. The index of TQ calculated 3 hours prior to the occurrence of heavy rainfall is also a good potential predictor. For the occurrence of light rainfall, K-Index parameter obtained at 6 hours prior to the events is the only significant predictor. Meanwhile, important predictors obtained at 3 hours prior to the events are the Hybrid Microburst Index, Jefferson Index and K-Index. In addition, other potentially prospective indicators include 500 mb Wind speed, Strom Relative Helicity, and SWEAT Index. Mathematical relationships of rainfall data as dependent variable and the selected parameters strongly suggest the existence of linearity component in the relationships.

Judul: Penggunaan Empirical Orthogonal Function (EOF) untuk Identifikasi Karakteristik Curah Hujan (Studi Kasus: DAS Ciujung-Cidurian)
Abstrak: Rainfall in Indonesia is highly varied in space and time. The purpose of this research was identify spatial and temporal rainfall pattern, examine impact of ENSO on rainfall variability, and obtain the location of stations which had great impact on rainfall variability. The method used Empirical Orthogonal Function (EOF) and Rotated Empirical Orthogonal Function (REOF). From EOF obtained annual and seasonal rainfall variance dominated by monsoon system. Type of mountain topography also contributed on rainfall variability. EOF seasonal temporal patterns related with ENSO. It was seen from high value of correlation between EOF coefficient and SOI. Correlation between EOF1 with MAM, JJA, and SON period respectively -0.467, 0.413, and 0.32. EOF2 correlated with DJF and SON period with correlation respectively -0.555 and -0.588. Rotated Empirical Orthogonal Function (REOF) was used to see the contribution of each observation station by rotating the EOF. Type of rotation is varimax rotation.The result of rotation showed factor1 was determined by two station, Ragas Hilir and Jongjing station whereas other factors were determined by one stasion only.

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.
