Kelengkeng Super Sleman (KSS) is a new variety of Dimocarpus longan L. developed at Sawitsari Research Station, Sleman, Yogyakarta. As the key of agroecosystems, insects play an important role in aiding the process of pollination of flowers. The research was aimed to study the diversity and pollination effectivity of insect pollinators on Kelengkeng Super Sleman (Dimocarpus longan L.) in Sawitsari Research Station, Sleman, Yogyakarta. The purposive sampling method including active and passive was used to explore the diversity of insect pollinators. Observation was conducted on three ranges of time, morning (08.00 to 09.00 am), noon (11.00 am to 12.00 pm), and evening (03.00 to 05.00 pm). The result showed that 19 families identified and 21 families unidentified from active and passive methods with Calliphoridae and Formicidae had the highest flower-visiting activity in the morning, noon, and evening. Besides that, uncovered panicles successfully pollinated with an average of 114 flowers, while covered panicles only 43 flowers. In conclusion, both Calliphoridae and Formicidae were the most KSS pollinators and the flower cover hinders the pollination process.
Penggunaan Antibiotics Growth Promotors (AGP) sintetis dalam pemeliharaan ayam broiler menyebabkan efek negatif jangka panjang. Penggunaan infused water buah naga merah (IWBNM) sebagai suplemen alami sangat diperlukan. Penelitian dilakukan guna mengetahui pengaruh IWBNM terhadap pertumbuhan ayam broiler. Rancangan acak lengkap menggunakan 5 kelompok dengan tiga ulangan adalah desain penelitian yang digunakan. Setiap ulangan berjumlah 20 ekor DOC. IWBNM diberikan melalui air minum. Perlakuan dilakukan hingga umur 21 hari. Perlakuan terdiri atas P0 (Kontrol) air biasa : P (Perlakuan) konsentrasi buah naga. Kelompok perlakuan yaitu 1 = konsentrasi 0,25% ; 2 = konsentrasi 0,5% ; 3 = konsentrasi 1% ; 4 = konsentrasi 2%. Data penelitian diuji dengan One Way ANOVA, dengan uji Least Significant Difference (LSD) dan Duncan sebagai uji lanjutan. Hasil pengujian, 1 ml IWBNM mengandung total flavonoid sebesar 676,19 µg. Pemberian IWBNM selama 21 hari secara umum dapat meningkatkan performa pertumbuhan ayam broiler. Pengukuran morfometri dan berat badan pada hari ke-21 merupakan indikator peningkatan performa pertumbuhan ayam broiler dengan rata-rata performa paling tinggi terdapat dalam kelompok P4 dibandingkan dengan P1, P2, P3, dan P0. Sedangkan untuk rasio organ visceral terhadap berat badan, IWBNM tidak berpengaruh signifikan baik pada organ jantung atau hepar
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
