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

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

Dusun Putak, yang terletak di Desa Loa Duri Ilir, Kabupaten Kutai Kartanegara, Kalimantan Timur, menghadapi permasalahan peningkatan volume sampah organik seiring dengan berkembangnya sektor pariwisata. Sampah organik, yang berasal dari sisa makanan, daun, dan ranting, memiliki potensi besar untuk didaur ulang menjadi pupuk organik yang bermanfaat. Namun, pengelolaan sampah organik di daerah ini masih belum optimal karena kurangnya pemahaman masyarakat dan terbatasnya infrastruktur pengelolaan sampah. Penelitian ini bertujuan untuk meningkatkan kesadaran dan keterampilan masyarakat dalam mengelola sampah organik melalui pelatihan pembuatan pupuk cair dan padat. Sebanyak 30 peserta dari berbagai latar belakang mengikuti pelatihan yang difokuskan pada pembuatan pupuk cair menggunakan mikroorganisme pengurai (EM-4) dan pupuk padat melalui bahan baku komposting. Hasil pelatihan menunjukkan bahwa masyarakat memperoleh pemahaman tentang pentingnya pemanfaatan sampah organik, serta keterampilan dalam mengolah sampah menjadi pupuk yang dapat meningkatkan kesuburan tanah dan produktivitas pertanian. Selain itu, pelatihan ini juga memberikan manfaat ekonomi bagi masyarakat, karena mereka dapat mengurangi ketergantungan pada pupuk kimia dan mengurangi jumlah sampah yang dibuang. Program ini diharapkan dapat mendukung keberlanjutan pertanian yang ramah lingkungan, menciptakan lingkungan yang lebih bersih, serta meningkatkan kesejahteraan masyarakat setempat.

Abstract

Public perception plays an important role in the success of mangrove planting activities. The community interacts directly with the mangrove ecosystem, so their perceptions will influence whether or not they will support and participate in planting activities. This study aims to determine the community's perceptions of mangrove planting activities in Sepatin Village, Mahakam Delta. The main data in this study were obtained through interviews. Interviews were conducted with 50 respondents who were selected purposively based on their involvement in mangrove planting activities. The research aspects consisted of four categories, namely knowledge, perception, participation, and future expectations. The data in this study were analyzed using descriptive statistics and presented in the form of diagrams and percentages. The results of the study show that 98% of respondents are aware of the mangrove planting activities carried out in Sepatin Village. The community has a very positive response to the planting activities, with 68% strongly agreeing and 32% agreeing with the activities. Mangrove planting activities have a positive impact on increasing fish catches and improving environmental quality. Several things need to be improved in mangrove planting activities, namely the need to involve the community in the planning and implementation of activities and to raise public awareness of the importance of mangrove ecosystems. Another thing that needs to be improved is the expectation that the government will provide adequate facilities and training for the community to support and enrich their knowledge on how to manage and utilize mangroves sustainably.

Abstract

The nursery phase represents a critical early space in plant cultivation, which is highly susceptible to pest and disease incidence. Mentawir Nursery, as one of the largest seedling centers in East Kalimantan, plays a strategic role in supporting reforestation programs, including for Indonesia’s new capital city (IKN). This study aims to identify and document the types of pests and diseases affecting five tropical fruit crops, as well as to analyze the incidence and severity. The five plant species observed in this study are Citrus sinensis, A. integer, Psidium guajava, Mangifera indica, and Dimocarpus longan. The research method employed is Simple Random Sampling, with observations conducted on 20 individuals from each plant species. The collected data include attack levels, symptoms, and signs of pest and disease infestations.The results indicate that four plant species experienced a 100% attack frequency, while one species had an 80% attack rate. The severity of the attacks ranged from moderate to severe. The observed disease symptoms included leaf spots, leaf blight, loss of leaf tissue, internal leaf tissue loss, leaf tumors, and leaf curling. Identified infestation signs included the presence of whiteflies (Hemiptera), larvae (Diptera), small beetles (Coleoptera), as well as larvae and pupae (Lepidoptera).These findings serve as a basis for pest and disease management at Mentawir Nursery to enhance seedling success and plant productivity.
