Judul: Analisis Frekuensi Aliran Tinggi pada Beberapa Daerah Aliran Sungai di Pulau Jawa
Abstrak: Information about highflow frequency and its magnitude is needed for sustainable watershed management. The objectives of this research were to determine highflow threshold and to analyse highflow frequency of Ciujung, Brantas and Bengawan Solo river basin. Long term daily streamflow data were analysed using annual maximum series (AMS) and partial duration series (PDS). Exceedence frequency 5% was chosen as highflow threshold. Based on the threshold, return period of highflow from PDS and AMS was compared. Analysis result showed highflow threshold values of Bengawan Solo, Brantas and Ciujung watershed were 1,304 m3/s, 668 m3/s and 298 m3/s respectively. Log Pearson Type III was used to estimate highflow values at greater return periods. The plotting position of AMS showed smaller discharge than PDS at the same return period. While data analysis showed AMS discharge in various return period tend to be greater than PDS

Abstrak: Hydrological drought is a condition of water below normal and also a propagation of meteorological drought. The objectives of this study are to determine the thresholds level, to analyse drought characteristics, and to analyse frequency of hydrological drought in Ciujung, Brantas, and Bengawan Solo River basins. In this study, the hydrological droughts were identified by threshold level method. The 80-percentile (Q80) from flow duration curve was used to determined the threshold (Q0). The study reveals that the threshold of Ciujung, Brantas, and Bengawan Solo River basins 17.6 m3s-1, 73.1 m3s-1, dan 46 m3s-1, respectively. Minimum duration (dmin) amounting to 10 days was the criterion of hydrological drought events. Maximum durations of each river basin amounting to 134 days, 150 days, and 167 days, respectively, and maximum deficit volumes amounting to 153.789 x 106 m3, 501.824 x 106 m3, 495.853 x 106 m3, respectively. Bengawan Solo has the highest frequency of number of droughts which have duration more above 100 days than another.

Judul: Studi pendahuluan pengaruh pemberian minyak mimba pada gambaran histopatologi kulit telinga kelinci yang terkena skabies
Abstrak: Penelitian ini bertujuan untuk membandingkan efektivitas minyak mimba dengan obat (krim) paten anti skabies yang mengandung lindane dan usnic acid pada kulit telinga kelinci yang terinfeksi skabies secara alami melalui pengamatan histopatologi. Sebanyak 9 ekor kelinci skabies dengan tingkat keparahan yang sama dibagi menjadi 3 kelompok perlakuan yaitu kelompok kontrol (1 ekor), minyak mimba (4 ekor) dan obat paten (4 ekor). Dari kelompok perlakuan minyak mimba dan obat paten masing-masing dieuthanasia satu ekor kelinci setiap minggu selama 4 minggu, untuk diambil kerokan kulit dan kulit telinganya guna pemeriksaan keberadaan tungau dan gambaran histopatologinya (Pewarnaan HE). Pengamatan histopatologi dilakukan dengan analisis deskriptif. Hasil pengamatan histopatologi menunjukkan pengobatan skabies dengan minyak mimba selama empat minggu sudah mampu membunuh semua tungau namun pada akhir pengamatan lesio berupa acanthosis dan rete ridge masih terlihat jelas. Obat paten membunuh tungau lebih cepat dibandingkan minyak mimba, namun minyak mimba lebih baik dalam menyembuhkan hiperkeratosis. Kata kunci: minyak mimba, obat paten, skabies, tungau, histopatologi, kulit.
