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.
拉瓦尔是一种特殊的巴厘岛食物，由杨桃植物的叶子制成，通常在巴厘岛的传统活动中供应，如寺庙节日或婚礼派对。酸甜杨桃的叶子是用来制作这种传统食物的。本研究对这些植物叶片的酚类和单宁含量进行了分析，以期探讨其作为抗氧化来源的潜力。众所周知，酚类化合物具有中和自由基和稳定单线态氧的抗氧化活性。该化合物具有通过螯合金属离子或抑制催化自由基形成的酶系统(如环加氧酶、单加氧酶或黄嘌呤氧化酶)来减少自由基的能力。[4]报道酚类化合物含量高的植物往往具有较高的营养和抗氧化活性，单宁是一种多酚类化合物。这种化合物在任何植物中都大量存在。这种化合物具有结合蛋白质、生物碱和明胶的能力。该化合物在人体中起着非常复杂的作用，如螯合金属离子、沉淀蛋白质、生物抗氧化剂等。结果表明，酸星果和甜星果叶片的酚含量分别为2830.99/100 mg GAE和1959.77/100 mg GAE，单宁含量分别为18810.43 mg/100 g TAE和11035.75 mg/100 g TAE，表明酸星果叶片的抗氧化活性优于甜星果叶片。

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.

Hepatogenous photosensitization is one of the ruminant diseases with symptoms of dermatitis or eczema of the skin accompanied by liver damage. The disease is caused by the compounds of toxic lantadene A and lantadene B which are secondary metabolites of Lantana camara plant. This research was carried out on January 2017. The material used in this study was preserved organs of the labia and lingua of dead three year old cow (Bos sondaicus). Samples were taken from Pakutatan Village, Jembrana, Bali. Identification of organ samples, histological preparation and histopathological examination were conducted at the Disease Investigation Center (DIC) 6, Denpasar, Bali. The preparation of labia and lingua samples used the paraffin method with Hematoxylin and Eosin staining. The tissue structural damages found were necrosis, inflammatory cell infiltration, congestion and tissue bleeding. The data obtained were analyzed statistically by One Way Anova test with a confidence level of 95%. Based on the results, dead Bali cow which consumed a large numbers of Lantana camara plants showed that the highest number of cell damage was at the picnotic stage of cell necrosis (cell death) in the labia organ significantly (P<0.005), while the highest bacterial invasion was found in the labia organ with an average percentage of 12.40%.

One of the nutrients that can be given to brood feed fish to improve reproductive performance and egg quality is vitamin E. Vitamin E has a very important role in increasing fish reproduction because vitamin E functions as an antioxidant that can maintain the presence of fatty acids and prevent fat oxidation in the fish cell membrane and can accelerate the secretion of reproductive hormones. This study aims to determine the effect of vitamin E in feed at different doses on the level of gonad maturity of tilapia. The research was conducted at the Fisheries Laboratory of the Faculty of Marine and Fisheries, Udayana University from July to August 2020. The samples of fish tested were tilapia (Oreochromis niloticus) obtained from the Teratai fishing pond, Sanur Bali. Vitamin E used was Ovagrow Vit E with a vitamin E content of 50%. The CRD method (completely randomized design) was used with four treatments and three replications. The doses of vitamin E that were mixed into the feed were 0, 100, 300, and 500 mg/kg of feed. The results showed that the administration of vitamin E mixed in the feed at different doses had a significant effect on the achievement of gonad maturity level, gonad somatic index (GSI), and Fecundity (P <0.05). Provision of vitamin E at a dose of 300 mg/kg of feed was the best dose for ripening tilapia gonads. The gonad maturity level developed up to maturity stage IV, the GSI value was (3.56 ± 0.46) and the fecundity value was (1379 ± 289).
维生素E是一种能提高鱼的繁殖性能和蛋品质的营养物质。维生素E在提高鱼的繁殖能力方面起着非常重要的作用，因为维生素E是一种抗氧化剂，它能维持脂肪酸的存在，防止鱼细胞膜中的脂肪氧化，并能加速生殖激素的分泌。本研究旨在探讨饲料中不同剂量维生素E对罗非鱼性腺成熟度水平的影响。该研究于2020年7月至8月在乌达亚纳大学海洋与渔业学院渔业实验室进行。所检测的鱼类样本为来自Sanur Bali Teratai渔池的罗非鱼(Oreochromis niloticus)。所使用的维生素E为含有50%维生素E的Ovagrow Vit E。采用CRD法(完全随机设计)，4个处理，3个重复。饲料中维生素E的混合剂量分别为0、100、300和500 mg/kg。结果表明，饲料中添加不同剂量的维生素E对黄鳝性腺成熟度、性腺体细胞指数(GSI)和繁殖力均有显著影响(P <0.05)。在饲料中添加300 mg/kg的维生素E是罗非鱼性腺成熟的最佳剂量。性腺成熟度发展到成熟期IV, GSI值为(3.56±0.46)，繁殖力值为(1379±289)。

This study aims to determine the profile of leachate, and seawater in the Suwung waste processing area (TPA Suwung). The method used in this research was descriptive quantitative. The results showed a high profile of untreated leachate with a TSS value of 9.407 mg/L, pH with a value of 8.17, DO with a value of 0.063 mg/L, BOD with a value of 375.5 mg/L, and COD with a value of 5.776 mg/L. The treated leachate with a TSS value of 4,987 mg/L, pH with a value of 8.52, DO with a value of 0.063 mg/L, BOD with a value of 321.9 mg/L, and a COD value with a value of 3.069 mg/L. Meanwhile, the seawater profile was classified as good with parameter values of TSS with a value of 76 mg/L, DO 7.54 mg/L, pH 7.54, BOD with a value of 13.6 mg/L, COD with a value of 64 mg/L. The existence of TPA Suwung has a negative impact and influence on seawater in the area. Revitalization efforts are needed to carry out leachate water treatment so that the effluent quality can be improved for the quality of water around TPA Suwung.
