Abstract

Kelulut bees have different habits when building nests between species. Tetragonula fuscobalteata is a type of the kelulut bee that is widely cultivated. Collecting bee colonies is generally carried out using various techniques, including nest dismantling, grafting, and bait techniques. Much research has been conducted on broodstock of kelulut bees, such as colony propagation techniques and the use of nest grafting methods, but research on the behavior of placing kelulut bee colonies in new nest boxes, especially on the T. fuscobalteata species, has never been carried out and done a lot. Therefore, this study aims to provide data regarding the behavior of placing T. fuscobalteata kelulut bee colonies in new nest boxes and measuring the temperature and humidity in new nest boxes sprayed with propolis extract liquid. This research used a direct observation method on new nest boxes that had been sprayed with propolis extract, and propolis was attached to the box entrance hole. The results showed that the movement behavior of the T. fuscobalteta bee colony from the old nest to the new nest occurred on the third day after repairing the nest and building the nest in the form of making honey bags, eggs, and bees. Bread occurs for 5 days. The ideal temperature in the nest is between 27.7 0C-29.70C, and the ideal humidity is between 70%-80%. The results of this research can be a reference for kelulut honey bee breeders, especially the T. Fuscobalteata, about the propagation of kelulut bee colonies

Abstract

The Biodiversity Park PT Tirta Investama Cisalak Subang Regency has an area of ± 5,800 hectares which has social, economic and environmental benefits. The Biodiversity Park is one of the efforts to support Indonesia's Nationally Determined Contribution target in mitigating climate change by increasing plant land cover, especially tree-level plants. Tree-level plants at a young age can increase carbon stocks in biomass. Younger stands can absorb more carbon than older stands. Climate change can cause natural disasters such as landslides. Landslides that occur in the work area can cause carbon stock loss. Data were collected by census by inventorying diameter at breast height and total height. Data analysis on standing tree volume used a specific gravity of 0.507 and biomass expansion factor of 1.33. Carbon potential research on Acacia mangium to determine the carbon potential of Taman KEHATI which is carried out by census and to determine CO2 absorption. Acacia mangium is an invasive plant that can grow on critical land and marginal land and has fast growth so that it can be used as one of the types for planting activities on post-landslide land. The aboveground carbon biomass research results in units per hectare are 1.690 tons/ha, carbon absorption of 0.794 tons/ha, and CO2 absorption of 2.912 tons/ha.

Abstract

ampe Marta Cave Tourism is located in Kutai National Park, Kutai Kartanegara Regency, East Kalimantan, and is one of the natural tourism areas with high biodiversity. The tourist route in this area offers natural beauty and a habitat that supports the lives of various butterfly species. This study aims to identify plants that are food sources (nectar) and non-nectar, types of butterflies, and the characteristics of pollen from each food plant. This study uses the transect method, namely taking samples of flowers and butterflies along the route, and the acetolysis method to see the morphological characteristics of pollen. The results of the study showed that there were 19 species from 11 families of nectar-eating plants identified as being utilized by butterflies (imago) as a source of nectar, where Ageratum conyzoides (Asteraceae), Asystasia gangetica (Family Acanthaceae), Leea indica (Family Vitaceae) were the dominant species that were often visited. In contrast, non-nectar feed such as minerals, rotten fruit, and animal feces, where out of 14 butterfly species identified, 11 dominant species sucked minerals on the banks of rivers or mud puddles, two species visited rotten fruit, and one species was seen in animal feces. Nectar feed has the characteristics of large and round-elongated pollen, which is more efficient for sticking to the insect's body. In contrast, the round-elongated oblate shape in Oxalis barrelieri shows strategic differences in the transfer of varying pollen norms, such as echinate and scabrate. The results of this study can be a reference for butterfly researchers to provide an overview of the diversity of nectar-producing plant feed along with its morphological characteristics and non-nectar feed utilized by butterflies on the Sampe Marta Cave tourist route

Abstract

The local communities in the interior of Kalimantan have long utilized plants from the Zingiberaceae family as traditional medicinal ingredients, especially for postpartum care. Many species of Zingiberaceae are retained in postnatal care because they are effective in alleviating and healing ailments. This study aims to review the potential diversity of Zingiberaceae species used in traditional medicine after childbirth and to identify their chemical compound content. The method used is a literature review with an analysis of scientific literature from the past 10 years discussing the utilization of Zingiberaceae by the community in Kalimantan in managing mothers after childbirth. The results show that there are ten species and four genera of Zingiberaceae that are frequently used, namely Alpinia, Kaempferia, Curcuma, and Zingiber. The plant organ that is utilized is the rhizome, processed in various ways such as boiling, pounding, or turning into powder before being consumed or applied to the body. The compound content in Zingiberaceae includes curcumin, gingerol, and shogaol, which have immunomodulatory, anti-inflammatory, and antioxidant activities, playing a role in postpartum treatment for women. This research emphasizes that Zingiberaceae plays an important role in traditional postnatal treatment, and further studies are needed to support the preservation of local knowledge, as well as conservation and sustainable utilization.

Abstract

The seedling phase is a critical stage in plant development, where the presence of plant-disturbing organisms (PDOs) can significantly reduce seedling quality and viability, particularly in rehabilitation species such as Samanea saman (Trembesi). This study aimed to analyze the intensity of pest and disease attacks, identify the types of PDOs involved, and describe the symptoms and signs of infestation observed in S. saman seedlings at the Tectona Nursery, KHDTK Bukit Soeharto, East Kalimantan. A simple random sampling method was applied to select 50 seedlings from a total population of 1,000 four-month-old individuals. Data collection was conducted through direct field observation of physical plant conditions, severity scoring, and documentation of symptoms and signs of biotic attack. The results showed that all sampled seedlings were affected, with an infestation intensity reaching 65.2%, classified as heavily infested. The observed symptoms included defoliation, foliar tissue loss (skeletonizing), leaf spots, leaf blight, and stem boring. Identified signs of attack included larvae from the order Lepidoptera and  mealybug (Pseudococcidae) and aphids, which are suspected to be the primary agents of tissue damage. These findings underscore the importance of monitoring pest and disease populations and implementing ecologically based Integrated Pest Management (IPM) strategies tailored to the nursery microclimate. Technical training and coordinated IPM implementation are essential to enhance seedling resilience and support the success of tropical forest rehabilitation.
