Abstract

Seawater intrusion is the entry of seawater into the land through the soil pores. Seawater intrusion harms sanitation activities. Surabaya constitutes a city with a high population density, which leads to high demand for water that is not proportional to the water input that cause seawater intrusion. Mitigation efforts to minimize the occurrence of seawater intrusion were by planting mangrove forests which act as coastal protection systems. The purpose of this study was to determine the water quality of the wells in Kenjeran and Rungkut, as well as to determine whether the presence of mangroves could affect the water intrusion mitigation. Samples were taken from 2 stations in Kenjeran and Rungkut with 3 sampling points and 3 repetitions. The parameters measured were consist of salinity, electrical conductivity, chloride, and total hardness. The samples of laboratory results were analyzed comparatively with the Kruskal Wallis test. It showed that the water in the coastal areas of Kenjeran and Rungkut was categorized as saline water with an average salinity value ranging from 3.1–7.2 ppt. Electrical conductivity values ??ranged from 6916-7993 mmhos/cm. Chloride values ??ranged from 1825-3848 mg/l. Total hardness values ??ranged from 320-1025 mg/l. Based on the values ??above, the quality of well water in both locations is classified as having experienced seawater intrusion. The existence of a mangrove forest landscape has no significant effect on mitigating seawater intrusion, this is presumably because the low percentage of mangrove cover (3.2%) cannot degrade seawater intrusion in Rungkut.

Abstract

Polymerase Chain Reaction (PCR) adalah suatu teknik sintesis dan amplifikasi DNA secara in-vitro yang digunakan untuk identifikasi hewan, tumbuhan maupun mikroorganisme dengan DNA barcoding. Identifikasi secara molekular menggunakan metode berbasis PCR perlu dilakukan pada ikan hiu muda (juvenile) karena belum terlihatnya karakter kunci untuk identifikasi ke tingkat spesies sehingga identifikasi berbasis morfologi sangat sulit dilakukan. Selain itu, kondisi demikian juga tidak mendukung kelestarian ikan hiu, karena dalam fase ini hiu belum memiliki kesempatan memijah sekali dalam siklus hidupnya. Penelitian ini bertujuan untuk menentukan kondisi optimal untuk amplifikasi DNA dan mengidentifikasi ikan hiu muda (juvenile) menggunakan metode DNA Barcoding. Amplifikasi dilakukan pada lokus cytochrome oxidase subunit I (COI) dengan modifikasi temperatur suhu pada tahap annealing. Hasil penelitian menunjukkan modifikasi amplifikasi dapat dilakukan dengan penggantian temperatur suhu annealing. Hasil PCR terbaik diperoleh pada suhu annealing 55oC. Hasil identifikasi ikan hiu muda (juvenile) yang didaratkan di Pelabuhan Perikanan Pantai (PPP) Muncar dengan metode DNA Barcoding pada gen COI adalah Prionace glauca.

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.

Abstract

Abstract Histamine is an amine biogenic compound, frequently reported to cause poisoning among people who consume fishes with high level of histamine. Such compound is produced by histamine producing bacteria (HPB) belong to family of Enterobacteriaceae. Histidine decarboxylase produced by HPB plays a central role to convert free histidine in the fish meat into histamine, resulting in accumulation of histamine in the fish meat. Many efforts, including low temperature storage, ozone, and brine treatment) have been applied to cope with/prevent histamine accumulation in seafood products. However, those methods have some disadvantages, such as costly or have potential to change texture or structure of the products being preserved. In this review therefore, some aspects (including application of lactic acid bacteria (LAB) to control histamine production, characteristics of LAB required, tolerance of LAB to high level of salt, and the role of LAB to suppress HPB growth, and suppression of histamine production) are comprehensively reviewed. All information was extracted from related scientific articles published in the last decade. Keywords: Allergy; Biogenic agent; Histidine decarboxylase; Lactic acid bacteria; Tuna

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

The estuary area of the Tukad Badung river has the potential to experience heavy metal pollution because of its location for various domestic and industrial wastes also has dense shipping activities around it. This study aims to identify the heavy metal content of Cd and Zn in water, sediment, root, and leaf samples of Sonnetaria sp. that grows in the area. The results obtained from the analysis of the heavy metal content of Cd and Zn in water samples were 0.006 mg/L and 0.014 mg/L. The results of the analysis of heavy metal content of Cd and Zn in sediment samples were 0.406 mg/kg and 15.462 mg/kg, respectively. This shows that water and sediment samples are still below the applicable quality standards. The Bioaccumulation Factor (BCF) value shows that the roots and leaves of Sonnetaria sp. can accumulate heavy metal Cd by 0.034483 and 0.041872 and accumulate heavy metal Zn by 0.011059 and 0.016751. The calculation of Translocation Factor (TF) of Cd metal of 1.214286 and Zn of 1.51462 shows that Sonnetaria sp. belongs to the category of phytoextraction (TF>1). Based on the Igeo index, the estuary area of the Tukad Badung river is classified as unpolluted to moderately polluted by heavy metals Cd (Igeo: 0.436517) and not contaminated with Zn metals (Igeo: -2.76359).

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.
