Abstract

Activities in the subak area display close integration between ritual patterns and agricultural procedures. This research aims to reveal socio-religious ideology in the Anggabaya East Denpasar subak’s texts. Research methods include the matching method and the agih method, with data obtained through interviews and direct observation of several respondents taken by sampling. In this subak, farmers practice high respect for God Vishnu and Dewi Sri, considered to be the givers of prosperity in the rice fields. Work in the rice fields is not only done physically but is also based on a religious aspect full of offerings and prayers. For example, farmers pray to Ratu Betara Sri, asking for safety when working in the rice fields by offering biukukung offerings. The agricultural process is directed through ritual stages, including ceremonies for rat pests. The farmer conveyed a prayer to Jero Ketut, begging the rats not to disturb him and asking for safety, "niki tiang nawegang ring jero ketut niki, ampunang ngusak asik, titiang nunas keselametan, mangde mekaon." Overall, the existence of religious and ritual elements in subak reflects the strong connection between spirituality and agricultural activities, creating harmony in the life of an agricultural society.

Abstract

Mangrove forests are an ecosystem that has an important role and function for the environment. Mangrove forests have ecosystems that are very beneficial to humans directly or indirectly. Apart from that, the mangrove ecosystem also has other important functions, namely as a catcher of sediment and as a prevention of erosion and as a soil stabilizer in estuary areas. Data collection was carried out in March using several methods, namely BCF, TF, and Igeo. Sampling was carried out using the Rhizopora type of mangrove mucronata at 3 different stations. The heavy metals tested in this study were zinc ( Zn ) and cadmium ( Cd ). In the highest sediment values for Zn and Cd were 15.516 and 0.532 respectively. In water, the highest levels for Zn and Cd are 0.020 and 0.006 respectively. The highest BCF root values for Zn and Cd are 0.00896 and 0.0609 respectively. The highest leaf BCF values for Zn and Cd are 0.02417 and 0.04487 respectively. The highest TF values for Zn and Cd are 2.68784 and 0.92857 respectively. The Igeo value for Zn is in the unpolluted category and CD is in the slightly polluted category

Abstract

The diversity of mangrove species in an area can be observed through morphological structure, anatomy, as well as palynology. Palynology is a study of pollen that frequently used as a reference to support data in identifying mangrove species. Mangrove areas in Bali have patchy distribution, one of which can be found in the Batu Lumbang area. Batu Lumbang is a mangrove area that is part of the Ngurah Rai Forest Park. Observation of the micromorphological characteristics of pollen in the Batu Lumbang mangrove forest area was carried out through the acetolysis method with modification. Eleven mangrove species were sampled, comprised of Aegiceras corniculatum, Avicennia marina, Bruguiera gymnorhiza, Ceriops tagal, Exoecaria agallocha, Lumnitzera racemosa, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, Sonneratia caseolaris, and Xylocarpus granatum. The results of observations on pollen from eleven species of mangroves show similarities of pollennits, monads. In addition, other pollen characters such as aperture type, pollen shape, and pollen size categories found vary among the samples observed. These characters can also group several species that have the same family or genus. In turns, these can be used as diagnostic character to distinguish one species with another.

Abstract

Mangrove ecosystems are able to support biological and ecological life cycles and provide welfare for coastal communities. Pest outbreaks that attack seedlings to mangrove trees often cause ecological losses throughout the TAHURA Ngurah Rai Bali area. The ecological interactions of barnacle pest species in mangrove ecosystems are very complex and highly detailed studies. There is empirical evidence that the attachment of barnacles is strongly associated with allelochemical compounds produced by mangroves. This study aims to inventory the attachment of barnacles (arthropods) to several types of mangroves in the TAHURA Ngurah Rai area of Bali. This study used a purposive sampling method to pay for the location of the observations. Quadrant transects were used to organize the classification of the mangrove plots, barnacle densities being calculated for each transect. The density of barnacles was calculated on the number of barnacles attached to the mangrove plants, then recorded the types of plants attached, types of barnacles, types of planting and the number of individuals for each mangrove classification. The study showed that barnacles planted most of the mangrove seedlings at all stations, while the classification of tree plots only had barnacles attached at station 3. The number of attachments of Amphibalanus sp. the highest was found at station 3 of the R. mucronata tiller classification of 881 individuals, while no attachment of barnacles was found at all stations for S. alba mangroves. Overall, the attachment of barnacles was higher in R. mucronata tillers and had the potential to reduce their growth productivity in the field. Efforts to control barnacles really need to be done to increase the success of planting mangroves in TAHURA Ngurah Rai, Bali.

Abstract

Birds are an important component of balancing ecosystems and have a reciprocal relationship and close dependence to their environment. The high number of bird species found can indicate the ecological role of the environment, either for finding food and shelter, or for nesting and breeding areas. Udayana University Bukit Jimbaran Campus, with a total land area of ??27,649 ha, still has plenty of green area. This condition provides great potential as habitat for various bird species. This study aims to identify the bird species found in Udayana University Bukit Jimbaran campus area. The method used was the point count method at 11 observation points that was determined by purposive sampling. The indices calculated were the diversity, uniformity, dominance, and relative abundance. From this study, 30 bird species from 18 families were recorded with a total of 571 individuals scattered at each observation point. Based on the calculated indices, the diversity of bird species in Bukit Jimbaran Udayana University campus area was considered as moderate, with a stable species distribution, and low dominance (no species dominates). Keywords: abundance, birds, diversity, dominance, evenness
