ABSTRAK Lebah tak bersengat merupakan serangga penyerbuk utama pada labu siam di daerah neotropika. Di Indonesia, informasi tentang penyerbukan pada labu siam belum tersedia. Penelitian ini bertujuan untuk mempelajari fenologi pembungaan labu siam, peran Heterotrigona itama (Cockerell), dan Tetragonula laeviceps (Smith) (Hymenoptera: Apidae) dalam penyerbukan labu siam. Pengamatan meliputi banyaknya bunga jantan dan bunga betina, volume nektar, konsentrasi gula nektar, durasi, dan laju kunjungan, serta persentase buah terbentuk. Tanaman labu siam menghasilkan bunga jantan lebih banyak dibandingkan bunga betina dengan nisbah 18:1. Tidak ada perbedaan volume nektar dan konsentrasi gula pada bunga jantan dan bunga betina. H. itama dan T. laeviceps yang mengunjungi kedua tipe bunga, dengan puncak kunjungan harian terjadi pada pukul 08:3010:30 WIB. Terdapat perbedaan yang signifikan pada durasi dan laju kunjungan antara H. itama dan T. laeviceps. Muatan polen H. itama (2137,50±184,49 butir) lebih tinggi dibandingkan dengan T. laeviceps (1675,00±110,47 butir). H. itama memindahkan polen ke stigma (14,1±4,1 butir) lebih banyak dibandingkan T.laeviceps (9,8±3,1 butir). Bunga betina yang tidak dikunjungi serangga gagal membentuk buah. Kunjungan tunggal H. itama dan T. laeviceps pada bunga labu siam menghasilkan persentase buah terbentuk berturut-turut sebesar 60 dan 40%. Persentase buah terbentuk lebih tinggi 8085% pada perlakuan penyerbukan terbuka yang mengindikasikan bahwa kunjungan yang berulang kali dapat meningkatkan peluang keberhasilan penyerbukan.

The management of natural resources based on socio-economic and ecology development has led to a focus on the bioeconomy in the policy discourse of non-timber forest products (NTFPs). Honey is an important NTFP with high socio-economic value, and its production involves millions of Indonesians. This article reviews the current status of honey-producing bee management, cultivation and harvesting system, marketing and socio-economic values, and the industry’s environmental function in Indonesia. This research utilized a meta-narrative review method to collect data and information from Google Scholar, Scopus, Science Direct, ResearchGate, Sinta, and Garuda. The study showed that the four bee species, namely Apis mellifera, Apis cerana, Apis dorsata, and stingless bee, are the most common species in honey production in Indonesia. The four species have specific characteristics based on habitat, production capacity, derivative products, management intervention to meet honey product standards, and sustainable livelihoods. The value chain of bees’ major products, such as honey, propolis, pollen, royal jelly, wax, and other derivative products, involves the distribution of honey to all involved communities, including beekeepers, honey gatherers/hunters, intermediate traders, and the processing industry. This study also found a significant association between environmental sustainability statutes that affects functional sustainability and economic function. The finding parallels the global trends that put forward a forest-based bioeconomy approach to forest resource management. The policy must be strengthened in managing relationships among supporting actors for sustainable honey production.
Stingless bee honey (SBH) is an astounding ‘miracle liquid’ with countless medicinal properties for various diseases such as gastroenteritis, cataracts, as well as for wound-healing. However, knowledge regarding it is still rather scarce. Henceforth, it is intriguing for us to contemplate on the less-studied stingless bee and its honey in particular. First and foremost, the antimicrobial ability of honey from eight different stingless bee species was tested to further proven its health benefit. Homotrigona fimbriata honey showed the highest antimicrobial activity with inhibition against five bacteria; Serratia marcescens, Escherichia coli, Bacillus subtilis, Alcaligenes faecalis and Staphylococcus aureus. The next aim of our study is to characterize their honey bacterial community via the use of 16S rRNA amplicon sequencing technology. A total of eight bacterial phyla, 71 families, 155 genera and 70 species were identified from our study and two of the stingless bee species honey were determined to have the highest bacterial diversity compared to other six stingless bee species, namely Heterotrigona erythrogastra and Tetrigona melanoleuca. Furthermost, Lactobacillus malefermentans was thought to be the native dominant bacteria of SBH due to its predominant presence throughout all studied species. The aforementioned SBH’s antimicrobial results and characterization study of its bacterial diversity are hoped to carve the pathway towards extending its probiotic ability into our everyday lives.
