Abstract

SariDanau di Taman Nasional Bromo Tengger Semeru (TNBTS) adalah kaldera atau kawah  raksasa, tetapi intensifikasi pemanfaatan lahan di sekitar danau berupa pemukiman, lahan pertanian dan pariwisata alam berdampak terhadap  danau. Penelitian dilakukan di Danau Ranu Pane dan Ranu Regulo, kawasan TNBTS, Provinsi Jawa Timur, dengan tujuan untuk mengetahui perubahan ekosistem danau dan rekomendasi strategi konservasi. Metode penelitian dilakukan dengan menganalisis kualitas air (fisik, kimia dan mikrobiologi) dari Danau Ranu Pane dan Ranu Regulo. Hasil penelitian menemukan bahwa ekosistem Danau Ranu Pane telah tertutupi oleh tumbuhan air jenis ki ambang (Salvinia molesta Mitchell)sekitar 80% yang menyebabkan peningkatan kandungan Biology Oxygen Demand (BOD) dan Chemical Oxygen Demand (COD), diikuti penurunan Dissolved Oxygen (DO) dan pH. Danau Ranu Regulo memiliki nilai kesuburan yang lebih tinggi (N/P=16,24) dibandingkan Ranu Pane. Hasil penelitian ini merekomendasikan agar pihak pengelola kawasan melakukan mitigasi untuk mengurangi risiko pencemaran melalui penyadaran masyarakat dan wisatawan.

Abstract

The use of alternative feed for Sunda pangolin in captivity is one way to cope with a shortage of feed. The aims of the research was to determine the impact of the use of alternative feed toward feed consumption and daily weight gain of pangolin in captivity. The research was conducted at Research Forest Dramaga, Bogor. The research material used by 4 individual pangolin consists of 2 males and 2 females with an average weight of 4.28 ± 0.22 kg. Research using 4x4 Latin Square Design, with 7 days of preliminary period and 14 days of data collection. The treatment applied were 4 alternative feeding i.e A= 50% kroto + 50% egg; B= 50% kroto + 50% tofu; C= 50% kroto + 20% egg + 30% tofu; D= 50% kroto + 18% egg + 26% tofu + 6% termites. The results showed that the effect of alternative feed not significantly (P<0.05) on feed consumption and body weight gain pangolin. Pangolin with treatment C consumed feed based on dry matter as much as 63.08 grams per day or 10.46% from body weight and the biggest weight gain 35.0 grams per individual per day.
