Abstract

Cows are one of the ruminant animals and farm animals that have a higher economic value compared to other livestock such as chickens, goats, buffalo and others, so many people build cattle farming businesses. In this case, the health of farm animals is one of the main factors that determine the successful production of cows. The study aims to detect the type of eggs from parasitic worms in cow feces and the degree of infection based on Total Standard (Egg Per Gram). Fecal sampling is done randomly from traditional breeder cows in Teluk Sepang Lembar Subdistrict. The sample number of 10 community cattle farms. Identification of the type of worm was carried out at UPTD Animal Hospital and Veterinary Laboratory of Animal Husbandry and Animal Health Office of West Nusa Tenggara Province. Furthermore, quantitative examination uses the buoyant method (Flotation method) and qualitatively with the Mc. Master method that calculates the number of eggs per gram (EPG) of feces. The results showed 6 negative samples and 4 positive samples infected with parasitic worms,and  2 types of worm eggs of the nematode class namely Trichostrongylus sp. and Chabertia ovina , and 1 species of cestoda class namely Moniezia sp. Based on the standard total EPG (Egg Per Gram) feces it is known that the degree of infection of the type of worm eggs Trichostrongylus sp., Chabertia ovina and Moniezia sp. It is low level.

Abstract

The use of food plant species by local communities is very important to study using the concept of ethnobotany. The purpose of this study was to determine the diversity of plant species, the use of food plants and how to process them at the Joben Resort, Mount Rinjani National Park. This research method is a field survey method which consists of interviews, observations, identification of plant species and data analysis. Determination of the sample using purposive sampling technique. Data was collected through semi-structured interviews and then collected plant specimens accompanied by key informants. Data analysis was carried out descriptively qualitatively after being processed in Microsoft Excel using simple statistical techniques. Based on the results of the study showed that there were 10 types of food plants obtained from the forest of Joben are: Goa (Ficus variegata), Cinnamon (Cinnamomum Burmannii), Jackfruit (Artocarpus heterophyllus), Candlenut (Aleurites moluccana), Salam (Syzygium polyanthum), Kentawong/Sintrong (Crassocephalum crepidioides), Jelijo/Tempuh Wiyang (Emilia sonchifolia), Fern (Diplazium esculentum), Bujak (Hedychium coronarium), and Jee/Putat (Planchonia valida). Utilization of food plants, among others, dried, made into spices, made into vegetables, direct consumption and sold. The most dominant use was fern 26%, followed by Jackfruit 21% and Salam 14%. Then the use of jackfruit plants was relatively large (20%) which could be used as vegetables, eaten directly and sold. Meanwhile, the most widely used plant parts were the leaves of food plants (66%) and fruit of food plants (21%).

Abstract

Microfouling is the attachment and colonization of bacteria and microalgae on the surface of objects immersed in the sea. So far, the control of biofouling on the surface of marine hulls has been using paints containing Tributylin Organotin (TBT) which have adverse effects on non-target organisms and are not friendly to the environment. The development of environmentally friendly antifouling paint is a solution to overcome the growth of biofouling. This study aimed to evaluate in vitro extract of Thalassia hemprichii as an anti-microfouling agent. Extraction of bioactive from Thalassia hemprichii was carried out by maceration. The filtrate is divided into five kinds of concentration, namely 0%, 25%. 50%, 75%, and 100% were then added to paint A as an anti-microfouling agent. The observed variables were microfouling biomass and the density of bacteria and microalgae attached to the steel plate. The results showed that with increasing concentration applied to the plate caused a decrease in the number of bacteria. The average decrease in each bacterial concentration was 84 x 10^6 CFU/mL, 65 x 10^6 CFU/mL, 41.5 x 10^6 CFU/mL, 28.7 x 10^6 CFU/mL, and 15.8 x 10^6 CFU/mL, respectively. Microalgae attached to the steel plate also experienced a reduction with the average values sequentially being 37 x 10^4 cells/mL, 14 x 10^4 cells/mL, 8 x 10^4 cells/mL, 5 x 10^4 cells/mL, and 2 x 10^4 cells/mL. Likewise, the microfouling biomass on steel plate also decreased in amount with the average values being 99.27 mg, 93.4 mg, 66.43 mg, 59.13 mg and 30.2 mg, respectively. Thus, Thalassia hemprichii extract has the potential to prevent the formation of microfouling.

Abstract

The high value and economic prospects of precious metals, have not been able to cover the environmental, health and social and economic impacts. The conversion of land functions and open pit mining activities as well as the amount of sediment waste causes very significant landscape and environmental changes. This study aims to evaluate the impact of using mercury and cyanide based on the knowledge and experience of actors (miners and gold processors) and the surrounding community on the island of Lombok. Field data collection was carried out by triangulation, namely in-depth interviews with actors and the community, and secondary/reference data from related agencies, especially the health center and several related research results. Gold extraction on the island of Lombok uses two methods which are carried out in stages, namely Amalgamation with mercury in the shelling process and Cyanidation with Potassium Cyanide in the bagging process. The results of the study show that the negative impacts of the mining process are more due to land clearing and miner safety. The impact of gold extraction using mercury is long-term, so it is difficult to identify the impact. Meanwhile, the impact of the use of cyanide is directly felt and seen by the public, especially in terms of decreasing the presence and yield of fish caught in rivers and coasts.

Abstract

Macrobenthos are organisms that live on the bottom of the waters have the characteristics of slow life movement and can survive for a long time so that they have the ability to respond to changes in the quality of a water. One way to determine the quality of seawater as a bioindicator of the stability of an ecosystem is to know the macrobenthos diversity index. This research aims to identify factors that influence the diversity of macrobenthos abundance on the coast of Teluk Dalem and Senggigi coast,and then to analyze the role of macrobenthos as a bioindicator of seawater quality on the coast of Teluk Dalem and Senggigi beach. The method used in this study is quantitative descriptive method. The results showed that the abundance of macrobenthos on the coast of Teluk Dalem and Senggigi beach had a relatively good diversity index, it is influenced by the physical, chemical and biological conditions of the environment.
