Due to climate change, many impacts occur on the sustainability of organisms, including the trigona bee. The occurrence of climate change not only affects decreasing honey production but also reduces the number of colonies. Presume that it can change the activity pattern of the trigona bee. This study aims to determine the pattern of activity demonstrated by Tetragonula laeviceps (Smith) colony in KHDTK Gunung Bromo UNS. This research was conducted in July 2021 at KHDTK Gunung Bromo UNS. The observation involved 128 colony boxes placed into four cages, namely cages A, B, C, and D. Observations on the activity of trigona bees starting from 06.00 WIB to 18.00 WIB, assuming trigona bee activity begins in the morning and end the activity outside the hive after sunset. The results showed that of the cages A, B, C, and D, the worker bees tend to be active in the morning (6-10 am) to collect nectars and resin. Before noon (10 to 12 noon), bee activities were decreasing. The activity of the worker bees increased between 12 to 2 pm and decreased again after that time slot. The food source most favored by trigona bees: Pinus merkusii (rp), Artocarpus heterophyllus (r), Spathiphyllum wallisii (np), and Xanthostemon chrysanthus (np). Resin extractions are very needed for bees as batumen materials, and this is due to natural enemies (lizards, ants, vespa wasps, and spiders) that appear around the cage.

K.G.P.A.A. Mangkunagoro I Forest Park is the one and only forest park in Central Java. As area of protection, life support system, and biodiversity preservation, K.G.P.A.A. Mangkunagoro I Forest Park plays an important role for life, especially for people around the forest area. To ensure this function, the sustainability of forest functions is determined by the presence of vegetation in the forest area. The purpose of this study was to determine the diversity of species, biomass and carbon stock of bamboo in K.G.P.A.A. Mangkunagoro I Forest Park. The diversity of bamboo species was observed by exploration method with an inventory. Then, based on the inventory data obtained, one species of bamboo was selected based on its number of clumps to determine the biomass and carbon storage. In the present study, there were 20 species bamboo at K.G.P.A.A. Mangkunagoro I Forest Park namely Bambusa balcoa, B. balcoa var. Capensis, B. bambos, B. blumeana, B. multiplex-green hedge, B. multiplex-alphanse karr, B. oldhami, B. tuldoides, B. vulgaris vulgaris, B. vulgaris vitata, B. vulgaris wamin budha, Dendrocalmus asper, D. asper thai, D. asper black, D. hamiltoni, Guadua amplexifolia, G. agustifolia, Oxytenanthera abysinica, Phyllostacys aurea, dan P. nigra. Furthermore, D. asper (petung bamboo) was the most dominated bamboo species. The number of D. asper were 758 clumps/ha and 3,213 reeds/ha. The average D. asper biomass was 6.02 kg/reed. Thus, the estimated biomass per ha was 19.5 tonnes/ha. In addition, D. asper has the ability to store carbon of 9.1 tonnes/ha.

Minyak atsiri dapat dijumpai di berbagai jenis tanaman yang tersebar di seluruh dunia. Indonesia setidaknya memiliki 40 jenis tanaman penghasil minyak atsiri komersial. Minyak atsiri memiliki berbagai manfaat, yaitu sebagai bahan baku kosmetik, obat-obatan, parfum, lilin, dan flavor. Salah satu atsiri yang diproduksi di Indonesia adalah citronella oil, citronella oil termasuk salah satu jenis atsiri yang populer digunakan sebagai anti-nyamuk, anti-jamur, dan anti-oksidan. Meskipun di Indonesia sudah berkembang luas petani yang berkebun serai wangi dan mengolahnya hingga menghasilkan minyak, akan tetapi masih banyak di antara mereka yang memproduksi citronella oil yang belum memenuhi standar. Oleh sebab itu, perlu adanya kajian mengenai faktor-faktor yang mempengaruhi kualitas citronella oil yang dihasilkan oleh usaha perseorangan agar dapat memenuhi standar industri. Untuk mengetahui kandungan citronella oil, dilakukan pengujian GC-MS. Hasil penelitian menunjukkan bahwa citronella oil yang dihasilkan memiliki kadar sitronellal yang lebih rendah dibandingkan industri besar, yaitu 11.37%. Sedangkan standar minimal untuk sitronelal adalah 35%, hal ini diduga berkaitan dengan umur panen, kualitas tempat tumbuh, kualitas mesin, dan pretreatment.

<p>Universitas Sebelas Maret (UNS) Surakarta mempunyai hak pengelolaan atas Kawasan Hutan Dengan Tujuan Khusus (KHDTK) Gunung Bromo UNS yang terletak di Kabupaten Karanganyar. Salah satu permasalahan dalam pengelolaan adalah masyarakat sekitar KHDTK Gunung Bromo UNS yang mata pencahariannya masih bergantung pada Hutan Gunung Bromo. Sebagian masyarakat di sekitar KHDTK Gunung Bromo UNS memanfaatkan beberapa lahan untuk kegiatan pertanian yang sangat dimungkinkan kerusakan lingkungan hutan akan terjadi. Untuk meningkatkan pendapatan masyarakat dapat melalui usaha budidaya lebah madu klanceng. Kegiatan pemberdayaan masyarakat ini dilaksanakan di KHDTK Gunung Bromo UNS dengan melibatkan Karang Taruna Kelurahan Gedong dan Karang Taruna Kelurahan Delingan, Kecamatan Karanganyar, Kabupaten Karanganyar. Tujuan kegiatan ini adalah untuk meningkatkan produktivitas masyarakat yang diikuti dengan peningkatan pendapatan dan kesejahteraan melalui produksi lebah madu klanceng. Bentuk kegiatan yang dilakukan berupa pelatihan kelas dan praktik budidaya lebah klanceng. Kegiatan pengabdian yang telah dilaksanakan mendapatkan respon positif dari pihak masyarakat, hal ini ditunjukkan melalui antusias para peserta pelatihan budidaya lebah Klanceng. Bersama Pengelola KHDTK Gunung Bromo UNS, tim pengabdian telah membentuk Kelompok Tani Pengelola Lebah Klanceng. Meskipun saat ini belum ada peningkatan pendapatan yang dirasakan oleh masyarakat, akan tetapi kesesuaian lokasi dan teknik budidaya yang relatif mudah untuk dilakukan menjadi faktor pendukung dalam berkembangnya budidaya lebah klanceng di KHDTK Gunung Bromo UNS.</p>

Indonesia is one of the biggest contributors to greenhouse emission globally. The trigger of such contributions can be traced to Land Use, Land Use Change, and Forestry (LULUCF). The problem of deforestation is complex, involving social, economic and political sectors. On the other hand, a holistic approach has not been widely discussed and implemented. This paper attempts to review and aims at providing potential answer on how to manage the forest and its relations with people in order to combat forest destruction caused by people. We believed that managing such relationship is the key to maintain the sustainability of the forest while keeping its roles and sustainability. Literature review was employed to develop a problem framework, and to develop alternatives in bridging the relationships between forest and local community. Collecting relevant literatures using keywords such as “forest and climate change mitigation”, “agroforestry and climate change”, “ecotourism and climate change”, and “agroforestry and ecotourism”, 96 articles were found. Further, through matching the content and the research goals of the articles, 13 articles were selected for further content analysis. We proposed agro-ecotourism as the alternative answer that can be pursued to balance the relationship between forest and people, especially in putting forest as an important partner rather than an exploitable asset. Hence, agro-ecotourism may help to increase the awareness among local community on the critical roles of the forest in the long term to fight against climate changes.
