Abalone (Haliotis squamata) is one of the fisheries commodities that have high economic value. This study was conducted to investigate contamination of Escherichia coli and coliform in Abalone cultivation ponds in the Musi Village area, Buleleng Regency, Bali. An experiment was carried out by taking water samples in the abalone pond every week for one month. The results showed that there was no difference between the total number of Escherichia coli and coliform. Water samples that were positive for coliform in the determination test had no differences in each sample with total coliform values (Colonies / 100mL) of 4, 3, 7 and 9 (MPN / 100mL) respectively. While the total number of Escherichia coli is shown after being grown in EMBA selective media which are 4, 3, 7, 4 (MPN / 100mL) respectively. Meanwhile, when compared with the number referenced from the Decree of the State Minister of Environment Number 51 of 2004 concerning Sea Water Quality Standards, the quality of seawater for aquatic cultivation in this study is still classified as Safe (<1000 MPN / 100mL).

Male fertility can be defined as the ability of the male reproductive system to impregnate a woman, whileinfertility is the condition of a married couple who have been married for one year or more and have had sexualintercourse regularly or without using contraception but do not have a pregnancy or offspring. About 10% ofmarried couples experience infertility. The main organ of male reproduction is the testes because in the testesthe process of forming spermatozoa and the hormone testosterone occurs. The hormone testosterone plays adirect role in the continuity of spermatogenesis. Testosterone is produced through a series of steroidogenesismechanisms in testicular Leydig cells. Several factors influence the course of steroidogenesis such as Leydigcells, steroidogenesis proteins, related genes to the influence of free radicals. These factors are closelyrelated to diet and lifestyle. This study is important to understand in efforts to prevent infertility in men.

Aquatic organisms or nekton have an important role in supporting the stability of the aquatic environment and human life. This study aims to determine the nekton type community, ecological index, and their conservation status in the Unda River area and around Jumpai Beach, Klungkung Regency, Bali. The study was conducted in July - August 2020. The study was conducted in 2 communities, namely Macrozoobenthos and Nekton. Macrozoobenthos samples were collected using the quadratic method in the Jumpai Beach area and the direct observation method along the Unda River. Nekton communities are collected through primary data using "survey methods" and secondary data through interviews with fishermen and local communities. The ecological index data were analyzed using the Shannon-Weiner diversity index (H'), dominance index (C), and uniformity index (E), while the data on Nekton type and conservation status were analyzed descriptively. The nekton species community in the waters of the Unda River and Jumpai Beach areas was obtained as many as 26 species in 21 families which were dominated by Kepala Timah (Aplocheilus panchax) and sepat rawa (Trichogaster trichopterus), while Nautica sp for the Macrozoobenthos community. The ecological index of the aquatic community is the Shannon-Weiner Diversity Index (H') value of 2.98 (moderate), the wealth index (R) of 3.95 (moderate), and the evenness index (E) of 1.21. (High). The highest percentage ratio of nekton communities was obtained by the Macrozoobenthos community, namely 53%, while the nekton species was 46%. Conservation status shows that 13 species are included in the LC (Least Concern) category, 12 species are included in the NE (Not Evaluated) category, and 1 species are included in the VU (Vulnerable) category.

BACKGROUND: The discovery of herbal ingredients for antihypercholesterolemic and to improve male reproductive function is very necessary due to high-cholesterol diet factors. Blumea balsamifera leaf extract (BBLE) is known to be able to increase the number and diameter of Leydig cells in rats given high-fat feed. This study was to conducted to determine the levels of total cholesterol, body weight, plasma malondialdehyde (MDA), Superoxide Dismutase (SOD), Luteinizing Hormone (LH) in high-cholesterol-fed male rats provided with BBLE.METHODS: This research utilized a randomized post-test only control group. Ethanol was used to extract the BBLE, which was then evaporated. For 21 days, 16 Wistar rats were given a high-cholesterol diet. To determine the effect of BBLE on the high-cholesterol diet, the samples were divided into two groups (control and BBLE group) on day 22. The treatments lasted 30 days. SOD, plasma MDA, LH, and total cholesterol were measured.RESULTS: The results showed that the SOD and LH parameters were significantly higher in the treatment of BBLE compared to the control group (p<0.05). The parameters of total cholesterol levels, bodyweight, and MDA of rats given BBLE were significantly lower than those of the control group (p<0.05).CONCLUSION: Our findings highlight that BBLE has antihypercholesterolemic and antioxidant effects. The BBLE also has potential to be used as a therapy to maintain male reproductive function because it has a positive effect on the hypothalamic-pituitary axis through increasing LH secretion.KEYWORDS: Malondialdehyde, Superoxide dismutase, Luteinizing hormone, Blumea balsamifera extract, High-cholesterol diet

Caulerpa is one of the seaweed that grows naturally in Indonesian waters such as those in Mandangin Island. This study aimed to identify Caulerpa sp. based on molecular analysis using certain genetic markers. This research is expected to provide information on the identification of macroalgae from Indonesia waters, especially Mandangin Island, Madura with the use of molecular analysis based on 18SrRNA primers. The two green seaweed samples from the Caulerpa genus in this study were successfully analyzed using 18SrRNA primers. The BLAST results of samples 1and 2 are related to Caulerpa taxifolia 18SrRNA, but in the phylogenetic tree result, Sample 1 was more closely related to Caulerpa sertularioides f. longipes. 18SrRNA primers have been used for molecular identification of green seaweed from Mandangin for the first time and this shows that barcode markers can be used for molecular identification of seaweed, specifically Caulerpa in the waters of Mandangin Island, Indonesia.
