Abstract

Penelitian ini bertujuan untuk mempelajari frekuensi kunjungan lebah Apis cerana dan Trigona sp. sebagai penyerbuk pada tanaman Brassica rapa. Metode yang digunakan dalam penelitian ini yaitu vocal sampling, dengan dua kali pengamatan. Pengamatan pertama pada bulan Januari dan pengamatan kedua pada bulan Juni 2014, masing-masing pengamatan dilakukan selama 10 hari saat bunga Brassica rapa sedang mekar. Parameter yang diamati meliputi, jumlah bunga yang dikunjungi per menit, lama kunjungan per bunga dan lama kunjungan per tanaman. Hasil pengamatan frekuensi kunjungan tertinggi yaitu pengamatan kedua pada bulan Juni. Trigona sp. mempunuyai jumlah bunga yang dikunjungan 3.14 bunga/menit, lama kunjungan 27.47 detik/bunga dan lama kunjungan 3.89 menit/tanaman, sedangkan jumlah bunga yang dikunjungan A. cerana 1.32 bunga/menit, lama kunjungan 6.22 detik/bunga dan lama kunjungan 1.64 menit/tanaman.

Abstract

Salah satu daerah di Indonesia yang menjadi sentra produksi kakao nasional adalah Sulawesi. Peningkatan produktivitas kakao berfokus pada pengendalian hama dan penyakit, optimalisasi penerapan teknologi budidaya, penggunaan jenis tanaman tertentu atau peremajaan tanaman yang telah tua, namun belum mempertimbangkan agen yang membantu dalam proses penyerbukan. Penelitian ini bertujuan untuk mengetahui jenis-jenis lebah pada kebun kakao di Lembah Napu, Sulawesi Tengah. Koleksi Hymenoptera dilakukan pada siang dan malam hari menggunakan sweep net dan light trap. Ditemukan sebanyak 4 spesies Hymenoptera yang termasuk dalam 2 famili yaitu Apis cerana., Apis dorsata, Ceratina sp., Champsomeris sp. Kelimpahan individu tertinggi di plot 2 yaitu 53 individu (49.07%), diikuti plot 1 yaitu 37 individu (34.26%) dan plot 3 dengan kelimpahan terendah yaitu 18 individu (16.67%). Keanekaragaman serangga tertinggi di Plot 2 yaitu H'=1.19, diikuti plot 1 yaitu H'=1.12 dan plot 3 dengan nilai terendah H'=0.98. Kemerataan serangga tertinggi di plot 3 dengan nilai E=0.34, diikuti plot 1 dengan nilai E=0.31, dan plot 2 dengan nilai terendah E=0,30. Lebah yang memiliki ukuran tubuh kecil yaitu Ceratina sp. dengan ukuran 8-10 mm. Namun dari segi perilaku kunjungan, Ceratina sp. tidak mengunjungi bunga kakao, sehingga lebah tersebut belum dapat disimpulkan sebagai lebah penyerbuk kakao yang potensial, meskipun memiliki ukuran yang kecil.

Abstract

Butterflies are well-established bio-indicators for assessing biodiversity and monitoring ecosystem responses to environmental disturbances. Understanding their habitat preferences can help identify critical areas that require conservation to sustain their populations. This study aimed to determine butterfly habitat preferences across six land-use types in Lore Lindu National Park (natural forest habitats: primary forest, secondary forest, agroforestry, and river streams) and the Lindu and Besoa Enclave areas (anthropogenic systems: cocoa plantations and settlements). Butterflies were collected using insect nets with sweep netting techniques along transect lines in each habitat. Each habitat was divided into three 200-meter-long transects, sampled using purposive sampling. Butterfly habitat preferences in natural and anthropogenic habitats were evaluated by comparing the number of individuals and species, the percentage of families, and species composition across habitats. 1,786 individuals from 85 species across five butterfly families were recorded in Lore Lindu National Park and the surrounding enclave areas. The highest number of individuals and species was found in agroforestry habitats (527 individuals, 46 species). In contrast, primary forests had the lowest number of species (14 species), and river streams had the fewest individuals (76 individuals). The highest diversity index was found in agroforestry habitats (H' = 3.33, E = 0.75), while the lowest was in primary forests (H' = 2.27, E = 0.51). The Nymphalidae family had the highest percentage of species and individuals, distributed across all habitats. Species composition similarity among butterfly habitats grouped them into three categories: primary forest‒river stream, cocoa plantation‒settlement, and secondary forest‒agroforestry. Natural habitats (primary forests, secondary forests, agroforestry, and areas around river streams) supported a higher number of species compared to anthropogenic systems like cocoa plantations and settlements. Therefore, natural habitats are crucial for supporting butterfly populations in Lore Lindu National Park and its surrounding areas.

Abstract

Kapas Island is one of the coastal tourist destinations that has a panorama of white sand with various types of plants and marine animals. Types of marine animals that are also found in coastal areas are gastropods. One measure of the biological system's sustainability is species diversity. The purpose of this study is to examine the gastropod diversity in the coastal region of Kapas Island, Tolitoli, Central Sulawesi. According to the findings of environmental parameter tests, temperatures with different substrates ranged from 29.3 °C to 32.6 °C, salinity from 33 to 38 ppt, and pH from 7.88 to 8.07. The types of Gastropods found in the study amounted to 34 species, from 26 Genus, 17 Families with 6 Orders and 2 subclasses. The Diversity Index Analysis's (H') total value for the Medium diversity category was 2.61, with findings ranging from 1.52-2.29. While the Evenness Index (E) rating ranges from 0.5 to 0.76, the medium-high evenness category's overall analysis value is 0.74. The dominance index (D) data showed no dominance amongst species, with a total index value of 0.1 and a range of 0.14 to 0.37. These results indicate that gastropods in the coastal area of ​​Kapas Island have moderate diversity and are evenly distributed. There is no dominance between species, which indicates that the gastropod community is stable with favorable environmental conditions.
