The concept of a smart city is indeed presented as an answer for efficient management of resources. Support for applications that are constantly evolving and the creation of a creative ecosystem in the field of technology, is a good first step towards a smart city. But in reality smart city is not only related to technology. This concept is a combination of new technology and intelligent thinking about the use of technology. As a city full of allure, Denpasar City along with its development and population growth, began to emerge various problems such as decreasing the quality of public services, congestion on the road, accumulation of garbage and other social problems. To solve these problems, Denpasar needs a smart, creative and innovative solution run by the ranks of government officials, from leaders to the lowest levels, and supported by the full commitment of all its citizens. Various efforts have been made by the Denpasar City government to facilitate services to the community, ranging from building a system to facilitate services to the community such as the health service system, population service system, government service system (e-Gove), and the public complaints system. To find out whether the efforts made by the government are related to the services provided to the community by implementing a smart city system. In this study various measurements of satisfaction levels were carried out to obtain significant conclusions. Of the five aspects studied, namely aspects of government services, aspects of government transparency, aspects of health services, aspects of population service, aspects of transportation services and aspects of water supply and electricity services, in general the people of Denpasar expressed satisfaction with a level of satisfaction of 76,312 and the level of satisfaction with aspects of health services have the highest level of satisfaction that is equal to 88,574.

Lawar, a special Balinese food made of leaves of star fruit plant, is commonly served in any Balinese traditional events, such as temple festival or wedding parties. The leaves of sweet and sour star fruit plant are used to make this traditional food. In this research, phenolic and tannin content of leaves of these types of plant were analyzed with a view to investigate their potential as antioxidant source. Phenolic compound has been well known to have antioxidant activity by neutralizing free radicals and stabilizing singlet oxygen. This compound has capacity to reduce free radicals by chelating metal ions or inhibiting enzymatic system, such as cyclo-oxygenase, mono-oxygenase or xanthine oxidase that catalyze formation of free radicals. [4] reported that plants with high content of phenolic compounds tend to have high nutritious and antioxidant activities Tannin is a compound belongs to polyphenolic group. Such compound is abundantly found in any plants. This compound has capacity to bind proteins, alkaloid, and gelatin. In human body, this compound play a very complex role, such as chelating metal ions, precipitating proteins, and functioning as biological antioxidant. The results of this study showed that the phenol content of sour and sweet star fruit plants were 2830.99/100 mg GAE and 1959.77/100 mg GAE, respectively, while the tannin content of these two plants were 18810.43 mg/100 gr TAE and 11035.75 mg/100 gr TAE, respectively, indicating that the leaves of sour star frit plant had better antioxidant activity than the sweet one.

Grey Mullet fish (Mugil cephalus) is one of the economically valuable fish in the waters of the Ngurah Rai Forest Park, Bali. This study was conducted to examine the relationship between the length and weight of the condition of Belanak fish caught in the waters of the Ngurah Rai Forest Park, Bali. The purpose of this study was to determine the description of the growth conditions of Belanak in the waters of Ngurah Rai Tahura, Bali will create a plan for sustainable management of Belanak Fish resources. Sampling was conducted in March 2019 to May 2019. Data analysis used was the relationship between length and weight and condition factors. Data processing is done by using the Microsoft Excel program. The results obtained showed that the mullet fish has a negative allometric growth pattern (long growth is faster than weight growth) equation W = 0.011 L2.195 and the coefficient of determination (R2) of 0.75 (75% growth in weight is influenced by growth long). Belanak fish caught in Ngurah Rai Tahura waters have a condition factor value (K value) ranging from 0.941 to 1.514 which indicates that Belanak is in good condition and is in its infancy.

Trigona is a stingless bee that protects itself by swarming and biting. The bee products that are widely used in addition to honey are propolis, wax and the royal jelly. Trigona bee is one of potentially honey producer that has not been widely known. One species of trigona bee found in Bali is the Trigona laeviceps. They are nested in the crevices of rocks or in the tree trunk. This research aims to determine variations of entrance shapes, food storage, and brood cells of T. laeviceps from different altitudes. Colonies were observed in the Laboratory of Animal Taxonomy, Biology Department, Faculty of Mathematics and Basic Sciences, Udayana University, and nest entrance was analyzed in the Analytic Laboratory, Udayana University. Colonies were collected from bamboo nest in a tubular form and wooden nest from wooden boxes. Nest entrance is either flat or protruded out of the nest in an oval shape. The form of the entrance is not affected by the altitude. The nest entrance contained around 0,05 % flavonoids. The size and shape of pollen and honey pots volume was lightly lager in colonies collected from altitudes more than 400m above sea level (0.058 ± 0.04 mm³) than colonies collected from altitudes less than 400 m above sea level (0.035 ± 0.03 mm³). Royal jelly pots and brood cells have also similar shapes, but the volume is larger in colonies collected from altitudes less than 400 m above sea level (0.015 ± 0.07mm³) compared to altitude of more than 400 m above sea level (0.011 ± 0.02 mm³ )

One of the diseases that attacks poultry especially laying hens (Gallus gallus domesticus) is colibacillosis, a disease caused by Escherichia coli. E. coli is a bacterium that has opportunistic properties, which is normally present in the digestive tract in a controlled amount, but when the condition of the chicken decreases, it can develop into pathogens. Kidneys are organs that are vulnerable to substances that are toxic and are also susceptible to bacterial infections. This study aimed to determine the histological structure of kidneys of laying hens (Gallus gallus domesticus) who died due to the infection of E. coli. The research was conducted at a Pathology Laboratory (BBVet), Denpasar. The hen’s kidneys were processed with the paraffin method and Hematoxylin-Eosin staining. Cell damage that occurs is observed by using the Image Raster application. The data obtained were analyzed with the scoring method. Renal histopathology parameters can be seen in the form of degeneration, necrosis, congestion, and inflammatory cell infiltration. The results obtained cell damages namely 46% of degeneration, 60% of necrosis, 44% of congestion and 76% of inflammatory cell infiltration.

Banana is a fruit that must be present in every activity of the Balinese people. Almost in every cultural and religious activity it is compulsory to present the banana fruit, even more Bali as a tourism area really need fruits including bananas. Therefore the need of bananas is highly demanded in traditional markets or supermarkets in Bali. Until now, the banana production in Bali is far below demand, therefore we still import form places outside of Bali. Banana has a high nutrient value due to nutrients found in it such as potassium and folic acid that is needed by the body. It is also a good so urce of calcium, phosphor, nitrogen, and vitamins such as vitamin A, vitamin C, and B complexes which helps to repair and regenerate tissues of the body. Banana plants can grow in many places, from low grounds until highlands and in various types of soil. Nevertheless for the optimal growth; fertile soil, crumbly thick, lots of humus, aeration, and a good drainage as well as enough water is all needed. By optimizing land use, banana plants are often planted as a sideline plant for plantatio n of coconut, cocoa, and coffee, as well as sideline plants for many other in-between plantations. The way of planting the banana is a conventional method that is commonly used by local farmers including those in the Angkah village. For growth of banana plants we must consider and ensure before planting a crumbly soil when it is solid, to make drainage, and to make levels in slopes. During plantation organic/compost fertilizers is needed as much as 15-20 kg for each hole for plantation. Organic fertilizers that are added influences the good production for both quantity and quality which makes the fruit tastier and has a higher nutritional value. There are some types of organic fertilizers that are used in this research that are: cow waste organic fertilizer, chicken waste organic fertilizer, pig waste organic fertilizer, goat waste organic fertilizer, and compost fertilizer with a dosage of 15 kg per plant. The placement of fertilizers for each places of treatment is conducted b y using a Random Group Design (RGD). The total treatments are 6 and are repeated 3 times. Planting is conduct ed on the 7th of July 2016 with a ground hole size of 60cmx60cm and a depth of 50 cm. The seedlings that are used are decedents that are 50-65cm in height. The specific aim that is wished to be achieved is the increase production of banana as sustainable food in Indonesia. The result up to the progress of this research was found that treatment with chicken waste fertilizer has given the best influence for growth of the banana plant, increased number of leaves, as well as increased height of the plants, all compared to the controlled. The increment of banana plant with chicken waste fertilizer was 63.33 cm for 3 months.Keywords: Banana, Nutritional Values, Production, Organic Fertilizer

The diversity of intertidal invertebrates in Bali was believed to be affected by human activities, due to high rate of development in tourism industry. In order to reveal the real natural invertebrate diversity, it is necessary to investigate it at a kind of untouched beach of Bali. This study was perform by comparing invertebrate diversity (species richness, density, community structure) and human activity (Type, frequency) in Merta Segara Beach, as the beach with frequent human activities, and Nyangnyang Beach, as the beach with little human activities. Invertebrates sample were taken within intertidal zone using line transect-quadrate during low tide. Human activities were observed in the afternoon from March to April 2016. The result showed a significant different in density and community structure between both Merta Segara and Nyangnyang beach as the consequences of different substrate type of both beaches. Walking on substrate or trampling was believed to be the most influencing activity for invertebrate diversity, especially for Merta Segara Beach. Next, a thorough study must be performed to conclusively tie the human activity to the alteration of invertebrate diversity in a coastal area. The high diversity, density and abundance of intertidal invertebrate of Nyangnyang Beach has literally shown that how diverse the biodiversity could be if the beach were protected from overexploited by tourism visitation and activity.
