      Abstract
      Informasi mengenai aktivitas mencari pakan (foraging) dan jenis tanaman sumber pakan penting untuk usaha peningkatan produktivitas lebah madu Apis cerana. Penelitian ini bertujuan menganalisis: (1) pola aktivitas harian lebah A.cerana yang dipengaruhi oleh faktor lingkungan, dan (2) keanekaragaman tanaman sumber polen di sekitar sarang lebah di Desa Mekarjaya, Kabupaten Pandeglang, Banten. Penelitian ini menggunakan dua koloni A. cerana yaitu koloni satu dan koloni dua dengan ukuran koloni yang sama. Perilaku yang diamati yaitu lebah keluar sarang, masuk membawa polen, dan masuk tanpapolen. Hasil pengamatan menunjukkan puncak aktivitas foraging koloni satupada pukul 07.40-08.50 WIB sedangkan koloni dua menunjukan aktivitas foraging yang rendah. Koloni dua melakukan absconding yang terjadi pukul 14.35- 16.30.Rendahnya aktivitas foraging pada koloni dua merupakan sinyal bahwa lebah akan melakukan absconding atau bermigrasi meninggalkan sarang. Hasil analisis vegetasi menunjukkan bahwa tanaman di sekitar sarang merupakan tanaman penghasil polen, nektar, atau polen dan nektar, didominasi oleh Cocos nucifera yang berpotensis menghasilkan polen dan nektar. Indeks keanekaragaman spesies tumbuhan menunjukkan bahwa keanekaragaman tanaman di area tersebut dikategorikan stabil. Hasil analisis jumlah spesies menunjukan bahwa jumlahspesies bernilai mendekati satu, sehingga dikategorikan jumlahnya relatif sama dalam berbagai tegakan.
       
      The information on honey bee foraging activities and food sources are important to increase the productivity of Apis cerana. This study aimed to analyze: (1) the daily activity pattern of A. cerana bees that is affected by environmental factors and (2) the diversity of pollen source plants around the beehive at Mekarjaya Village, Pandeglang Regency, Banten. This study used two colonies of A. cerana. The observed behaviors were bees leaving the hive, entering carrying pollen, and entering without pollen. This result showed that the peak of foraging activity in colony one occurs at 07.40-08.50. Colony two showed a low foraging activity that is a signal of the absconding bees or bee migrated. The correlation values between environmental factors: temperature, humidity, and light intensity compared to the honey bee activity was range from 0 to 1. The results of the vegetation analysis showed that the plants around the hive were plants that produce pollen, nectar, or pollen and nectar and the dominant was Cocos nucifera. The plant species diversity index showed that the diversity of plants in the area was categorized as stable. The results of species number analysis were close to one, thus the numbers were categorized as relatively the same in the various stands.
