Abstract

Proper and safe sanitation is the main foundation for public health and improving the quality of life. Although the majority of Indonesia's population has access to adequate sanitation, significant challenges are still faced in achieving safe and quality sanitation. This research aims to provide a comprehensive picture of sanitation conditions in Badung Regency, Bali Province, by focusing on key factors such as water sources, domestic wastewater, waste, standing water, and clean and healthy living behavior (PHBS). Using the Environmental Health Risk Assessment (EHRA) approach, this research involved surveys in six sub-districts with a total of 62 villages/urban village, involving 2480 female respondents aged 18-60 years as housewives. Data collected involved interviews, observations and questionnaires, with analysis carried out using EHRA tools. The research results show that Badung Regency faces five main challenges in sanitation, namely varied water sources, awareness of domestic wastewater which still needs to be improved, solid waste and waste management problems, risk of waterlogging and heterogeneous levels of PHBS in the community. The results of the Sanitation Risk Index (IRS) analysis show a number of villages/urban village with varying levels of risk, namely 18 villages/urban village with low risk, 14 villages/urban village with moderate risk, 2 villages/urban village with high risk and 28 villages/urban village with very high risk.

Abstract

Insects are the Arthropod phylum that has the highest diversity. One of the most common insects in Indonesia is the dragonfly (Odonata), which consists of the Anisoptera suborder and the Zygoptera suborder. This study aims to determine the dragonflies species that are found around the Udayana University Campus, Bukit Jimbaran, Bali. Sampling of dragonfly was carried out by sweeping technique using insect nets in the morning (08.00-10.00 WITA) and in the afternoon (15.00-17.00 WITA). Sampling was carried out at three different locations, including location I: Biology-Rectorate, Location 2: Dean of FMIPA-FTP, Location 3: Udayana Forest-Dam. Each location was repeated three times in the morning and evening. Species identification and species number calculations were carried out for analysis using the Shannon-Wiener diversity index (H'), evenness index (E) and Simpons dominance index (D). There are 8 species of dragonflies found and belong to two suborders. A total of seven species found belong to the Anisoptera Suborder and one species belongs to the Zygoptera Suborder. The overall diversity of dragonflies with a value of 1.83 is included in the moderate category, evenness is included in the even category with a value of 0.94 and a dominance value of 15% which indicates that no species dominates. Keywords: Diversity, Dragonflies, Udayana University

Abstract

Population growth in urban area directly or indirectly affects environmental quality. Waste is environmental problem that has long been of global concern and needs to be handled seriously so that it does not cause harmful impacts. Currently, waste in Bali Province is not only a problem in urban area, but has spread to rural area. Responding to the Bali Provincial government's policy, Dajan Peken Village in Tabanan Regency has established a TPS3R (Reuse-Reduce-Recycle Waste Management Site) for waste management with several waste management facilities and infrastructure. This research aims to identify community attitudes in source-based waste management, and understand community behavior in managing their respective household waste in Dajan Peken Village. The results of the research show the peoples in Dajan Peken Village already have a fairly good attitude in responding to Bali Governor Regulation No. 47 of 2019 concerning Source-Based Waste Management, however, public views regarding conventional waste management such as landfilling and burning can still be found. At the behavioral level, patterns of inappropriate waste management are still found in Dajan Peken Village, such as burning waste, hoarding it, not sorting waste, and so on.

Abstract

The existence of each megabenthos is related to the condition of coral reefs which act as habitats for various types of megabenthos species. Benthos are commonly takes advantage of the ecosytem of coral reef as a habitat to live and shelter in the coral niches from natural predators. This study aimed to determined the abundance of megabenthos and the percentage of coral reef cover, as well as the correlation between the abundance of megabenthos and the percentage of live coral cover in Amed Waters. Megabenthos data collection was carried out using the Benthos Belt Transect (BBT) method. Point Intercept Transect (PIT) was used to examined the coral percentage cover. Correlation of Pearson was used to analyzed the correlation between abundance of megabenthos and coral percentage cover. A total of 473 individuals with a total abundance of 0.26 ind/m2 were found in this study. Interestingly, there were no Acanthaster planci individuals found during the data collection. The condition of coral reefs was dominated by Dead Coral Algae (DCA), while the percentage value of live coral cover in Amed Waters were 19% to 35% in the damaged to moderate category, respectively. Pearson correlation showed a value of (r) 0.067 with a very weak positive category which indicates that there is a positive relationship between the two variables which indicating that the correlation of megabenthos abundance has no significant relationship with the percentage of live coral cover. Keywords: megabenthos; Amed; Pearson; dead coral algae

Abstract

Timbulan sampah yang masih belum dapat ditangani menjadi permasalahan di Kota Denpasar. Menurut Arfani dan Lestari (2021) kendala utama dari pengelolaan sampah adalah mengenai pendanaan untuk sarana dan prasarana. Untuk mengurangi beban yang timbul dari biaya pengelolaan sampah, pemerintah harus merencanakan pengelolaan yang efektif. Objek penelitian ini adalah timbulan sampah di Kota Denpasar di TPS 3 R Sekar Tanjung, TPS 3 R Kesiman Kertalangu, dan TPS 3 R Bung Tomo. Metode yang digunakan dalam penelitian ini yaitu metode deskriptif, yaitu dengan menghitung kapasitas pengelolaan sampah di TPS 3 R dan membandingkan antara biaya dengan manfaat pengelolaan sampah di TPS 3 R. Berdasarkan hasil penelitian ini dapat disimpulkan yaitu: Pengelolaan sampah pada TPS 3R Kesiman Kertalangu memiliki tingkat efisiensi yang paling tinggi yaitu 82,7%. Hal tersebut sejalan dengan jumlah mesin dan peralatan yang digunakan. TPS 3R Kesiman Kertalangu menggunakan total 9 mesin dan peralatan pada tahap pengolahan. Jumlah tersebut merupakan yang terbanyak diantara TPS 3R lainnya. Dari tiga lokasi penelitian, satu lokasi yaitu TPS 3 R Bung Tomo belum melakukan kegiatan pemilahan dari sumbernya, sedangkan dua lokasi lainnya telah melakukan kegiatan pemilahan dari sumbernya. Pada tiga TPS 3 R di Kota Denpasar, dua diantaranya memiliki B/C Ratio >1 yaitu TPS 3 R Sekar Tanjung dan TPS 3 R Kesiman Kertalangu yang mengindikasikan kegiatan pengelolaan sampah layak secara ekonomi dan TPS 3 R Bung Tomo memiliki B/C Ratio <1 yang mengindikasikan kegiatan pengelolaan sampah belum layak secara ekonomi.

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

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
