The Trigona spp (kelulut) bee is a non-stinging honey bee that belongs to the Apidae family. Kelulut is a social insect that lives in groups in a colony, where this bee colony defends itself by biting if disturbed. Kelulut usually make nests in tree holes, wall gaps and bamboo holes in the house, with simple materials that are used as nests such as wooden boxes, pieces of bamboo, coconut fruit, coconut shells, and earthen pots as long as the nesting material is tightly closed. Bee hives are a place of refuge for a bee colony from bacteria, fungi, viruses, and predators, as well as a place for honey, bee pollen, and bee eggs to grow. Kelulut nests are built from resin material derived from plants, besides that there is a door to the nest which is decorated with a funnel made of resin and has various shapes, some are short and some are long, depending on the type which serves as a place to enter and exit colony members. The entrance and exit of the nest not only serves as a pathway for entry and exit, but also serves as a marker for the nest. Kelulut nest entrances have various shapes, including funnel, oval, elliptical, round and irregular or without protrusions at the entrance. This study aims to determine the shape of the entrance to the Trigona spp nest in the Surya Perdana Mandiri Mangrove Forest Area. The method used is a survey, with roaming techniques. Observations were made on trees with kelulut nests. Data analysis using descriptive qualitative. The results found 2 species of kelulut, namely Heterotrigona itama Cockerell and Tetragonula laeviceps Smith. H.itama bees have 6 the shape of entrance and T.laeviceps bees have 4 the shape of entrance. H.itama bees have a funnel at the entrance and there are propolis around the nest. The H.itama entrance has a different shape in the form of a long and slender funnel and a short and large funnel. In addition, the funnel has a variety of colors, black, golden yellow, light brown, and dark brown. While T.laeviceps species do not have a funnel or nest entrance. This type only makes a hole as a place to enter and exit the nest and there is no propolis found around the nest.Keywords: Heterotrigona, mangrove, nest entrance, tetragonula, trigona
Proboscis monkey (Nasalis larvatus) is an endemic animal of Borneo including protected primate species as an endangered species status. This species listed as an endangered species caused by large population decline and habitat demage continues to threaten the proboscis population. This research was conducted in Taman Wisata Alam Tanjung Belimbing (TWATB) is a nature conservation area that supports the conservation of proboscis monkey. The purpose of this research is to collect the amount of proboscis monkey populations, so as to provide an overview of conservation efforts that must be carried out. The method was used the River Survey method. The result of Proboscis research based on the age level was found consisted average of 5 adult male individuals, 6 adult female individuals, 7 adolescent individuals and 5 childs. Estimation of the population is calculated using the King’s Method. Estimated individuals population is 12 individuals with a density of 25.5 individuals/km2.Keywords: Proboscis monkey, Population, Tanjung Belimbing, Paloh.
The management of forest honey in Nanga Lauk Village is still carried out modestly by the local community. The honeycomb tree is a tree that is tall, big, and sturdy with wide branches that bees naturally nest in. Forest honey belongs to the Apis dorsata forest bee which is the most productive honey bee in producing honey. This study aims to examine the way on how the management of forest honey in Nanga Lauk Village, Embaloh Hilir District, Kapuas Hulu Regency. A survey method with observation and interview techniques is employed in this study. Interviews were conducted with people who own the honeycomb trees. Respondents were selected using a census technique based on ownership of honeycomb trees. The data are obtained from respondents who own honeycomb trees with a total of 10 groups that have been studied. Based on the qualitative descriptive analysis, the Nanga Lauk Village community has carried out traditional honey management in groups for generations starting from forest area maintenance, forest honey harvesting, packaging, and marketing. From the results of the study, it can be concluded that the management of forest honey in Nanga Lauk Village still uses honeycomb trees which have been applied from generation to generation. This is one of the values to maintain and preserve the existence of forest honey bees in Nanga Lauk Village.Keywords: forest honey, Nanga Lauk Village, ownership of honeycomb trees, honey processing Abstrak Pengelolaan madu hutan di Desa Nanga Lauk masih dilakukan secara sederhana oleh masyarakat setempat. Pohon sarang lalau adalah pohon yang tinggi dan besar serta kokoh dan memiliki dahan lebar yang dihinggapi lebah untuk bersarang secara alami. Madu lalau berasal dari lebah hutan Apis dorsata yang merupakan lebah madu yang paling produktif dalam penghasil madu. Penelitian ini bertujuan untuk mengkaji bentuk pengelolaan madu hutan di Desa Nanga Lauk, Kecamatan Embalaoh Hilir, Kabupaten Kapuas Hulu. Penelitian ini menggunakan metode survey dengan teknik observasi dan wawancara. Wawancara dilakukan terhadap masyarakat yang memiliki pohon sarang lalau. Pemilihan responden dilakukan dengan menggunakan teknik sensus berdasarkan kepemilikan pohon sarang lalau. Penelitian ini memperoleh data dari responden yang memiliki pohon sarang madu sendiri dengan jumlah 10 kelompok yang telah diteliti. Berdasarkan analisis diskriptif kualitatif, pengelolaan madu lalau dilakukan oleh Masyarakat Desa Nanga Lauk secara tradisional, turun temurun dan berkelompok mulai dari pemeliharaan kawasan hutan, pemanenan madu hutan, pengemasan dan pemasaran. Dari hasil penelitian dapat disimpulkan bahwa pengelolaan madu hutan di Desa Nanga Lauk masih menggunakan pohon sarang lalau yang diterapkan secara turun-temurun. Hal ini merupakan salah satu nilai untuk mempertahankan dan melestarikan keberadaan lebah madu hutan yang ada di Desa Nanga Lauk.

Pesut adalah jenis lumba-lumba tanpa moncong yang hidup pada air tawar, payau dan asin termasuk kedalam golongan mamalia laut besar. Pesut ditetapkan sebagai spesies yang menjadi fokus dan prioritas upaya konservasi jenis di Indonesia karena termasuk kedalam spesies endangered. Jumlah individu yang terus berkurang dan meningkatnya ancaman membuat spesies ini semakin terancam jumlahnya. Penelitian bertujuan untuk menduga populasi pesut yang berada di Resort Sungai Perlu SPTN Wilayah II Taman Nasional Tanjung Puting yang dilakukan pada bulan februari yang mana menurut nelayan lokal adalah waktu yang paling tepat untuk melakukan pengamatan pesut karena kondisi gelombang laut yang sedang tenang. Metode yang digunakan dalam penelitian ini adalah Capture-Mark-Recapture dengan menggunakan foto sirip punggung sebagai identitas individu setiap pesut. Pendugaan jumlah populasi menggunakan analisis persamaan Chapman. Hasil penelitian mendapatkan jumlah populasi pesut sebesar 55 individu. Karakteristik sirip punggung yang mendominasi adalah bulat telur, segitiga, bercabang, dan datar. Kata kunci: pesut, populasi, sirip punggung, Taman Nasional Tanjung Puting
Ulin (Eusideroxylon zwageri) is a species of wood with high economic value that is difficult to find in the wild. Regeneration of E. zwageri is naturally very slow. Efforts to increase the procurement of E. zwageri seedlings can be done with a tissue culture technique. Through tissue culture, the seeds obtained will be uniform, have better quality and faster. This study aims to determine the effect and optimum concentration of IAA and BAP growth regulators on E. zwageri explants growth. The method used is experimental using a completely randomized design. Treatment factors are IAA concentration factor with 5 levels of treatment (0 mg/L, 0.5 mg/L, 1 mg/L, 1.5 mg/L, and 2 mg/L) and BAP concentration of 5 treatment levels (0 mg/L, 1 mg/L, 2 mg/L, 3 mg/L, and 4 mg/L). Each treatment was repeated 3 times. The results showed that the treatment of IAA concentration, BAP concentration and the interaction of IAA and BAP concentration affected the swelling of explants and growth of E. zwageri callus. The best concentration for callus explants was IAA of 2 mg/L and BAP of 0 mg/L, with a time of 12-13 weeks after planting.Keywords: BAP, E. zwageri, IAA, Tissue Culture
