Characterization of solitary internal waves in the northern Bali waters

Internal solitary wave (ISW) is an underwater wave, formed due to the evolution of internal tides. The presence of breaking ISWs in coastal areas can potentially influence coastal ecosystems through cross-shelf exchange mechanisms. The southern waters of the Kangean Island and the eastern waters of the Madura Island, known also as part of the northern Bali waters, have been an active habitat for ISW propagation. This study aims to identify and characterize ISW which potentially breaking onshore the Southern Kangean Waters (SKW) and the Eastern Madura Waters (EMW) using Sentinel 1 SAR (Synthetic Aperture Radar) imagery. ISW characterization was carried out using the Korteweg-de Vries (KdV) model. The ISW amplitudes which propagate to EMW varies from 1 - 28 m with a propagation speed of 1.60 - 1.98 m/s, while the ISW which propagate to the SKW has an amplitude of 1 - 60 m with a propagation speed of 0.83 to 2.17 m/s. The results show that the ISW propagating to the SKW has stronger amplitude, phase velocity, and horizontal-vertical velocities than the ISW propagating to the EMW. The maximum speed of the horizontal current triggered by ISW leading to the EMW is 0.03 - 0.17 m/s and the vertical velocity 0.11 - 4.53 cm/s; the maximum speed of horizontal velocity leading to the SKW is 0.02 - 1.29 m/s and the maximum speed of the vertical velocity 0.04 - 19.03 cm/s.

Kintamani Bali Chinese Ethnic Religious Hybridity: A Dualism of Cultural Identity

This research aim was to explore the form of religious hybridity carried out by the Kintamani Bali Chinese ethnic group as part of the diversity of Chinese ethnicity in Indonesia. Regarding religious hybridity in the Kintamani Balinese Chinese ethnic group, the reason for choosing thisresearch was because the Balinese Chinese ethnicity is different from the Chinese Indonesian ethnicity in general; here they find unification and assimilation with Balinese culture, resulting in a dualism of cultural identity. This research used a qualitative approach with ethnographicmethods, data collection through participant observation and in-depth interviews, and is supported by other secondary references. This research was analyzed using Homi Bhabha’s hybridity theory and Parson’s functional theory. Research results show since the arrival of ethnic Chinese in northern Bali, they have established economic and political relations with the Bangli kingdom, where there is a good relationship between ethnic Chinese and the king of Bangli, so that it has an impact on the social and cultural life of the Balinese Chinese ethnic, namely the existence of religious hybridity that occurs. The first can be seen in terms of religious rituals such as daily prayer activities, Second, there is hybridization in terms of places of worship, The third is hybridization in terms of religious ornamentsand worship facilities. The causal factor is the first one amalgamation, a belief and philosophy of life for the Kintamani Chinese ethnic group, the existence of past history and open relationships, high tolerance, opennessto differences, and not questioning religious issues. A new identity, namely the dualism of cultural identity attached to the Kintamani Chinese ethnic group. Therefore, this plays a role in the socio-cultural life of the village and creates harmony with the Balinese Hindu community.

Shadow zone mapping using parabolic equation method in the Bali Strait Waters

Shadow Zone is an area where sound waves cannot penetrate a water column due to deflection. This study aims to map the shadow zone based on oceanographic parameters in the Bali Strait. The data used are temperature, salinity, and depth for 31 days in the East Season (July) in the Bali Strait at two stations from the results of numerical modeling downloaded from the website https://marine.copernicus.eu/. Shadow zone simulation uses the parabolic equation method with certain parameter limits. The vertical temperature profile shows that the deeper the water is, the lower the temperature, whereas salinity is the opposite. The sound velocity is affected by the parameters of temperature and salinity. At the location of the 25 m transducers, the undetected medium beam is narrower than the location of the 110 m transducers so that the shadow zone with a 110 m transducer position has a broader area. The Shadow zone area in the northern Bali Strait is effectively detected using a frequency of 100 Hz. In comparison, in the southern part of the Bali Strait, it is effectively seen at a frequency of 38 Hz, with the respective transducer positions used at a depth of 25 and 110 m.

Architectural Physical and Spatial Characteristics of Chinatown Shop Houses in Singaraja City, Bali

Since North Bali is in a very advantageous location and can support navigation technology systems that are still basic, trade relations can be established through ships that frequently travel through the northern Bali region. Beginning in the northern region and a region that was influenced by the Port of Buleleng, Chinatown shophouses began to grow throughout time. The study uses a qualitative descriptive methodology to explain the conclusions drawn from both primary and secondary sources of information. The architectural features of Chinatown shophouses are discussed in this study, including their physical characteristics, figural qualities connected to their shapes and materials, and spatial characteristics relating to their functions and zoning of space. Physical characteristics are categorized into types of buildings according to the number of floors and the materials used, and the typology is based on the era in which the shophouse was constructed. The results of this study on spatial character reveal that a building’s ground floor is divided into front, middle, and back, with the front zone serving a commercial function, the middle zone serving a residential function, and the back zone serving a service function. On both the ground floor and the top floor, the altar room is always located in the front zone.

Decorative Features of the Temple Complex Pura Beji (Sangsit, the Island of Bali)

The author examines the sculptural decoration of the Pura Beji temple – a vivid representative of the style of sacred architecture and decorative plasticity of northern Bali. This temple complex is the sanctuary of the subak irrigation association. It is unique with a peculiar vocabulary of decor, rich texture of stone carvings, masterfully executed in a “pink” paras. The purpose of the article is to use the example of analysis of the decorations of temple buildings (Candi Bentar gates, Candi Kurung, Candi Laras altars, Apit Lawang) and samples of round sculpture to identify the characteristic features of the decorative desing of Pura Beji, to reveal the features of the iconographic reading of individual motifs and images, their spatial configuration. The work is based on empirical material from field studies conducted in April 2019 (Desa Sangsit, kabupaten Buleleng). The study of the temple decor was carried out using the methods of full-scale research, non-standardized interviews; comparative analysis; iconographic, compositional, artistic analysis of images. For the first time, the diverse repertoire of Pura Beji's plastics was analyzed through the prism of the leading iconographic program related to the cult of fertility and the specifics of Balinese Hinduism (with its rich mythopoetics, metamorphoses of the divine and demonic worlds). This predetermined the abundance of floral ornaments and chimerical, fantastic images in the decoration of the temple, their organic fusion. The role of active contacts of the northern coast of Bali with the cultures of Eastern civilizations and Western Europe in the formation of the original style of carving by Sangsit masters is also taken into account. The author comes to the conclusion that the decorative design of Pura Beji is characterized by: rethinking the codified patterns of decor, the use of original motifs and borrowed replicas; compositional freedom of ornamental constructions; continuous filling of the wall surface with sculptural decoration in relief, the applicative manner of applying the ornament. Also noteworthy is the hyperbolized way of articulating decorative elements, manifested in the reception of emphasized grotesque in the interpretation of zoomorphic images and the dominance of a large pattern of leaves and flowers.

Observed internal solitary waves in the northern Bali waters, Indonesia

Internal solitary waves (ISWs) in the northern Bali waters are frequently observed via satellite imagery, but in situ observations remain scarce. Here, we report the northward propagating Lombok solitary waves from shipboard acoustic current measurements. The four leading waves have amplitude of 45, 35, 30, and 25 m and typical mean phase speed of ∼1.8 m s−1. The waves generated strong northward currents of ∼0.8 m s−1 in the upper layer and triggered vertical velocity that reaches ∼15 cm s−1. Those observations suggest larger ISWs amplitude than recent numerical estimates at the same location. The shape of the four leading waves is consistent with the Korteweg–de Vries (KdV) model. The total energy density within the packet reached ∼147 MJ m−1, and the total mean energy flux per tidal cycle into ISWs is in the range [0.6 – 1.0] GW, representing a strong fraction of the total northward baroclinic tidal energy flux estimated from models.

The Projections of Climate Change using Conformal Cubic Atmospheric Model (CCAM) in Bali - Indonesia

Research on climate change was conducted in Bali, Indonesia, using the Conformal Cubic Atmospheric Model (CCAM), which works with the Representative Concentration Pathway (RCP) 4.5. The history data means average data from 1971 to 2000, climate projections with RCP4.5 scenario means average data from 2040 to 2069, and anomaly (climate change) is RCP4.5 minus history. The results represent the history of temperature between 22.5-27.5 0C and the projection between 25.5-29.5 0C. Temperature anomalies can be observed in much of northern Bali, which has increased from about 1.6 to 2.9 0C. There is a trend towards reduced (drier) humidity in most parts of Bali, particularly in the northern part of Bali. In contrast, a small amount in the south increases the (wetter) humidity. The comfort index of the Bali region in history is still relatively comfortable (20-26 0C). The projection condition RCP 4.5, there is no comfortable area with an index of more than 26 0C (hot and dry).

Hubungan Klorofil-a dan Suhu Permukaan Laut (SPL) Terhadap Hasil Tangkapan Ikan Lemuru Sardinella lemuru di Selat Bali Menggunakan Citra Aqua MODIS Tahun 2009-2018

Oceanographic parameters such as sea surface temperature (SST) and chlorophyll-a in the water can influence the productivity of pelagic fish such as Lemuru. Many studies have been conducted on the relationship between SST and chlorophyll-a and the fluctuations in the catch of Lemuru fish, especially using satellite databased sensing technology. Most of the research using satellite data is done in a short-term period (not climatology), so there are still a lot of unanswered questions. One of them is: how the correlation between the fluctuation in the number of Lemuru fish catches is related to SST and chlorophyll-a in the ENSO and IOD periods. The purpose of this study is to determine the distribution of SST and chlorophyll-a concentrations and their relationship with the yield of Lemuru fish catches in the Bali Strait from 2009 to 2018. Aqua Moderate Imaging Spectroradiometer (MODIS) satellite data level 2 from Oceancolor and data on the number of fish caught in the Bali Strait from the National Fisheries Port (PPN) Pengambengan and UPT PPP Muncar. The method is used with correlation analysis between SST and chlorophyll-a to the number of Lemuru fish caught. The monthly average SST in Bali Strait waters from 2009 to 2018 was approximately 24,76 0C-30, 11 0C, with an estimated monthly chlorophyll-a concentration of 0,10 mg/m3-3,68 mg/m3. The spatial distribution of SST tends to be low in the southern Bali Strait and tends to be high in the northern Bali Strait. The spatial distribution of chlorophyll-a appears to have a high value in the near land area. The cross-correlation test between chlorophyll-a and the number of Lemuru catches showed a positive correlation yield at the 4th month lag. While the correlation of SST to the number of Lemuru fish catches shows a positive correlation at lag (-1).

Consciousness-based education in Bali: a second- and third-person embedded multiple-case study of Negeri Bali Mandara

ABSTRACT Consciousness-based education has been described as both an innovative method for developing the consciousness, and thereby the creativity, learning ability and behaviour, of students, and a pedagogical approach designed to reverse negative trends in schools. For either purpose, it has in the last 20 years been implemented in hundreds of schools in 49 countries, for which a considerable body of literature documents its impact on the mental and physical health, learning ability, social relations, and academic achievement of students. However, while the approach has been implemented in two schools in northern Bali, Indonesia – SMA Negeri Bali Mandara and SMK Negeri Bali Mandara – the nature and scope of its potential impact on individual and collective life have yet to be examined. Using an embedded multiple-case research design, the present study seeks to fill this gap in the literature by exploring the experiences and viewpoints of current students, former students, teachers, a Principal, and parents of students participating in consciousness-based education in Bali. Results from this unique educational setting indicate that outcomes are somewhat consistent with international findings, but several unique characteristics of secondary education in Bali have emerged which shine further light on understanding this novel pedagogical approach to student development.

Representative benthic habitat mapping on Lovina coral reefs in Northern Bali, Indonesia

Abstract. Kartikasari A, Pristianto T, Hanintyo R, Ampou EE, Wibawa TA, Borneo BB. 2021. Representative benthic habitat mapping on Lovina coral reefs in Northern Bali, Indonesia. Biodiversitas 22: 4766-4774. Satellite optical imagery datasets integrated with in situ measurements are widely used to derive the spatial distribution of various benthic habitats in coral reef ecosystems. In this study, an approach to estimate spatial coverage of those habitats based on observation derived from Sentinel-2 optical imagery and a field survey, is presented. This study focused on the Lovina coral reef ecosystem of Northern Bali, Indonesia to support deployment of artificial reefs within the Indonesian Coral Reef Garden (ICRG) programme. Three specific locations were explored: Temukus, Tukad Mungga, and Baktiseraga waters. Spatial benthic habitat coverages of these three waters was estimated based on supervised classification techniques using 10m bands of Sentinel-2 imagery and the medium scale approach (MSA) transect method of in situ measurement.The study indicates that total coverage of benthic habitat is 61.34 ha, 25.17 ha, and 27.88 ha for Temukus, Tukad Mungga, and Baktiseraga waters, respectively. The dominant benthic habitat of those three waters consists of sand, seagrass, coral, rubble, reef slope and intertidal zone. The coral reef coverage is 29.48 ha (48%) for Temukus covered by genus Acropora, Isopora, Porites, Montipora, Pocillopora. The coverage for Tukad Mungga is 8.69 ha (35%) covered by genus Acropora, Montipora, Favia, Psammocora, Porites, and the coverage for Baktiseraga is 11.37 ha (41%) covered by genus Montipora sp, Goniastrea, Pavona, Platygyra, Pocillopora, Porites, Acropora, Leptoseris, Acropora, Pocillopora, Fungia. The results are expected to be suitable as supporting data in restoring coral reef ecosystems in the northern part of Bali, especially in Buleleng District.

Tsunami Hazard Potential Modeling as Tourism Development Considerations in the North of Lombok Strait

Currently, the central government and provincial governments of Bali and West Nusa Tenggara are promoting tourism development in North Bali and North Lombok. In the development of tourism, besides consider the potential of existing tourism objects, the economy, and its supporting facilities, the potential threats of disasters must also be considered. Based on historical records, one of the potential disasters in northern Bali and Lombok is a tsunami. This study aims to determine the height and the arrival time of the tsunami along the northern coasts of Bali and Lombok. This study was carried out by simulation and numerical modeling, using the TUNAMI Model. Modeling was carried out for 2 hypothetical scenarios caused by an earthquake from the Flores Back-arc Thrust. Base on this model, it is known that the height of tsunami on Trawangan Island is ± 6 m with an arrival time of ± 3 minutes, while on the north coast of Bali the height of the tsunami is ± 0.6 m with an arrival time of ± 21 minutes. The arrival times of the tsunami on the north coast of Bali and Lombok are so fast.

Growth and reproduction performance of sea cucumber (Stichopus sp.) fed with different feed regime

Growth and reproduction performance of sea cucumber (Stichopus sp.) fed with different feeding regimes. This study aims to know the effects of different feeding regimes on sea cucumbers' growth and gonad development. Sea cucumbers used in this experiment were collected from the natural habitat in Northern Bali waters. Five individuals of sea cucumber (BW 334 ± 58 g; TL 22,5± 3,5 cm) were placed in each of four concrete tanks size 0,85 x 2 x 0,5 m3 with flow-through water systems. There were two feeding treatments in this study: A) fresh benthos and B) a combination of fresh benthos and seaweed (Ulva and Sargassum). Feed was given as much as 2.5 to 5 %, once in the afternoon. Observed variables were the growth and gonad stage and the weight at the end of the experiment. The study showed that the different feeding regimes significantly influenced the sea cucumber growth and gonad weight, but not the gonad stage. Sea cucumber fed with a combination of benthos and seaweed performed better growth and higher gonad weight. The difference in the feed did not affect gonad development.

Antibiotics Resistance Level of Vibrio spp. Isolated From Northern Bali Area

One conventional method that usually done when the organism infected by pathogenic bacteria is using antibiotics, either with single or combination usage. However, the misuse of antibiotics dosages leads to resistance development of pathogenic bacteria. This study aims to determine the antibiotic resistance level of Vibrio spp. which was isolated from the waters of North Bali and to investigate the difference of resistance level between Vibrio spp. isolated from the cultivation area and outside the cultivation area. This research was conducted at the Microbiology Laboratory of BKIPM Denpasar and the Laboratory of Fisheries at the Faculty of Marine Science and Fisheries, Udayana University from November 2019 to February 2020. Antibiotic tests were carried out in vitro using 8 types of antibiotics namely tetracycline, oxytetracycline, enrofloxacin, ciprofloxacin, amoxycillin, doxycycline, ampicillin, and erythromycin with different concentrations of 0.5, 1, 2, 4, 8, 16, 32, 64, 64, 128, 256 and 512 ppm. and this test was carried out using a microplate reader to obtain absorbance values before and after incubation to determine the level of resistance of isolated Vibrios. The research showed that overall minimum inhibitory concentration (MIC) of Vibrio was below 100 ppm while the Vibrio spp. isolated from cultivation area have higher resistance level compared to outside cultivation area.

Early Symptoms of Modernism in Traditional Balinese Painting Began in Northern Bali

The history of significant changes in traditional Balinese art towards modern art took place in the 1930s in the village of Ubud, South Bali. Visual changes in Balinese art are unlike changes in modern art in the West or in Indonesian modern art. The visuals show a strong traditional style, although signs of modernity as this paper will argue, can be found. Modern Balinese art in Ubud in the 1930s actually started in North Bali in the 1870s. It was the role of two Dutchmen named Van der Tuuk and W.O.J. Nieuwenkamp, a linguist and academic artist, who contributed to the introduction of modern art to North Balinese artists. The interaction between the two Dutchmen and the local artists gave birth to arts that are slightly different from traditional arts in Bali. This paper will discuss the shift from traditional to modern painting done by Balinese artists in this early period that resulted in the transition of traditional to modern art through the changes in techniques and media; and themes and functions of these visuals. As such, this marks a shift from art that are no longer spiritual but lean more towards the profane.

SOCIO-CULTURAL DYNAMICS AND ETHNOLINGUISTIC VITALITY OF SEMBIRAN BALINESE

This paper reports our preliminary findings on the assessment of language vitality of Sembiran Balinese in the larger socio-cultural transformation of contemporary Bali. Sembiran Balinese, also known as Bali Aga, is a conservative mountain dialect of Balinese spoken by around 5,000 speakers in the Sembiran village, 30 km east of Singaraja northern Bali. The language and its culture reflect Bali in antiquity (Ardika, et al. 1991; Ardika, et al. 1997), with the language quite distinct from Lowland Balinese (Bali Dataran), for example in terms of its pronominal system and the absence of speech level system (Astini 1996, Sedeng 2007, Arka & Sedeng 2018). The study is based on the data collected through questionnaires focusing on subjective views of ethno-linguistic vitality such as in-/out-group interactions and domains of language use in contemporary multilingual settings, supported by ethnographic data. The analysis makes use of the current development in the sociolinguistics of vitality, particularly the notions of ethnolinguistic vitality (Giles, et al 1977) and theories of language shift and endangerment (Grenoble & Whaley 2006, Fishman 1991). The findings reveal that Sembiran Balinese appears to have a relatively strong linguistic vitality even though the speech community itself is a minority group in Bali.

Coral diversity on artificial reef from coconut shells in northern Bali, Indonesia

Artificial reef from natural product bioreeftek is very easy to apply and can be found in many tropical coastal areas namely coconut shells with natural coral recruitment. The purpose of this study was to calculate the percentages of coral cover, ratio and clustering. At the two research sites in North Bali, Pemuteran - Napoleon reef, depth 5-6m-reef slope found 13 species of live coral from 9 bioreeftek: Porites sp 32%, Pocillopora damicornis 13%, Seriatopora sp 10%, Acropora palifera, Acropora sp, Goniastrea sp, Favia sp, Pachyseris sp = 6%; Montipora sp - Echinopora sp - Favites sp - Fungia fungites and Leptoseris sp = 3%. At the Lovina - Adirama Temple, depth of 6m-reef flat was found in 14 species from 14 bioreeftek: Acropora palifera 24%, Pocillopora damicornis 21%, Porites sp 7%, Montipora sp 4% - Acropora sp - Pavona sp = 3%, Platygyra sp 2%, Acropora humilis - Millepora = 1%. Cluster Analysis showed all corals on two sites are correlated in percent cover, characteristics, influences and occurrences. Artificial reefs with natural materials such as coconut shells are necessary developed in addressing the degradation of coral reef ecosystem. The added value of bioreeftek is insertion/inserted method of coral.

Estimation of Seismic Hazard Potential and Attendant Potential Human Fatalities from a Scenario Earthquake on the Sanchiao Fault in Northern Taiwan

In this article, the seismic hazard potential in northern Taiwan, including Taipei City, New Taipei City, Keelung City and northern Taoyuan areas are estimated in the form of peak ground acceleration, peak ground velocity and Modified Mercalli Intensity as well as to assess attendant potential human fatalities from a scenario earthquake on the Sanchiao active fault in these areas. By using ground motion prediction equation method in a case of Mw6.88 resulting in the ShakeMap patterns of ground motion, showed the areas of PGA above 400 gals are located in the regions inside the yellow lines of the PGA contour map. Furthermore, the areas of PGA greater than 637 gal are located in the northern Bali and the border area of Sinjhuang and Shulin. Likewise, the high PGV area greater than 60 cm/s are located in the border area of Sinjhuang, Taishan and Shulin. In addition, from estimation of potential human fatalities for a scenario earthquake on the Sanchiao active fault, it is noted that potential fatalities increase rapidly in people above age 45. Total fatalities reach a high peak in age groups of 55–64. Another to pay special attention by Taipei City Government is the number and percentage of fatalities above age 85 are more in Taipei City with values of 419 and 8.54% than New than Taipei City with values of 319 and 5.02%. In addition, it is surprising that the number and percentage of fatalities are 1234 and 9.75%, respectively in Taoyuan City. Overall, the results of this paper will enable both local and central governments in Taiwan to take notice of potential earthquake threat in these areas, as well as to improve decision making with respect to emergency preparedness, response, and recovery activities for earthquakes in northern Taiwan.

Economic Analysis of the South-North Bali Connection Railway Plan in The Acceleration of Economic Equality Development in Bali, Indonesia

At present the economic development in the province of Bali between South and North Bali is very significant. This condition is presumed to be the transportation infrastructure for the connecting road of South Bali - the existing aiIDRort is not optimal. The alternative transportation infrastructure studied is the plan to build a railway line across South-North Bali. Mengwitani-Singaraja link road is required to be capable to provide more optimal accessibility so that there is an even distribution of economic growth.he indicators used in the feasibility analysis of economic aspects are net present value (NPV), benefit cost ratio (BCR) and economic internal rate of ruturn (EIRR) The price component is used by the shadowprice method. Costs calculated according to the life cycle cost of the project development. Benefits calculated include direct benefits in the form of passenger ticket income and indirect costs in the form of cost savings for existing road users, a multiplier effect, an increase in tourist visits to northern Bali. Economic analysis indicates that the planned North-North Bali railway line is worth proceeding, this is shown by the NPV indicator of IDR 860 billion, BCR of 1.11 and EIRR of 13.11% greater than the 12% price reduction rate. Although it shows that there is feasibility of economic studies, a strategy is needed to produce financial feasibility so that it can be offered in cooperation between government and business entities (PPP) in order to accelerate its developmen
