Abstract

This study aims to determine the condition factor (FK) of fish that live wildly on Lake Buyan and record the types of fish parasites that exist, by identifying parasites in fish samples caught by fishers both fishing with fishing rods and with nets. Then counting prevalence of types of parasites found.This study uses the descriptive exploitative research method, namely by conducting a series of observational activities on the object under study in this case are the fish that are on Lake Buyan both fish that have economic value and wild fish that have no economic value. Data retrieval techniques in this study were carried out by direct observation or observation of objects studied in the field, and microscope observations in the laboratory on sample fish. The condition factor (FK) is different for each type of fish and there is a decrease in FK in each fish, namely the observation period in August 2018. Nilem fish has FK which is 1.66 (less healthy) compared to other fish.In this study nine species of parasites were identified in seven species of fish, while the parasites were: Dactyrogilus sp, Gyrodactilus sp, Tricodina sp, Vorticellasp, Oodinium sp, Saprolegniasp, Argulus sp, Lernaeasp, Icthyoptiriussp. All of which belong to the ectoparasites which attack the outside of the body of the fish such as skin, scales, fins, gills and head.The prevalence of each type of parasite varies for each type and each observation period. The highest prevalence in June was Tricodina sp with a value of 5.71%. In July the highest was Saprolegnia sp 8.57%, in August the highest was Saprolegnia sp and Lernaea sp which amounted to 10%.

Abstract

Abstract Sindhu Beach is one of the beaches in the Sanur area that is used for various economic activities, such as recreational locations or marine tourism by involving many stakeholders that can affect the aquatic environment which is the habitat of marine biota, is phytoplankton. In addition, the presence of seagrass also affects the abundance and saprobity index of phytoplankton. The research was conducted in May 2021 at Sindhu Beach and the identification process was carried out in the laboratory of the Faculty of Agriculture, Warmadewa University. The method used is the descriptive method. There were 20 types of phytoplankton from five classes, namely Chlorophyceae, Diatomae, Bacillariophyceae, Cyanophyceae, and Dinophyceae classes. The highest abundance of phytoplankton in the third observation was 206.369 ind/l at Station 1 and the lowest at the third observation was 152.866 ind/l at Station 2. At Station 1, the lowest water saprobic index was 0.047 in the first observation, followed by the second observation at 0.130, and the highest at the observation third at 0.307. This value is included in the moderately polluted category. At Station 2, the lowest water saprobic index in the first observation was -0.538, followed by the second observation at 0.28 and the highest at the third observation at 0.523. This value is included in the category of lightly polluted. At Station 3, the lowest water saprobic index in the first observation was 0.307, followed by the second observation at 0.615 and the highest at 0.739. This value is included in the category of lightly polluted.

Abstract

Abstract This study aims to determine the intensiveness of sea urchins (Echinoidea) and the community structure of sea urchins in the seagrass ecosystem at Batu Jimbar beach, Sanur, Bali Province. In this study, the stations were determined based on the distribution and cover of seagrass so that there were three stations, namely station I located at the coordinates 115 ° 15'58.17 "E - 8 ° 41'52.87"S, while station II was located at coordinates 115 ° 15'59.34 "E - 8 ° 41'48.15"S, and Station III is located at coordinates 115 ° 16'0.16 "E - 8 ° 41'43.42"S. Sampling was carried out at the lowest tide at the three stations and analyzed using species composition, density, relative density, diversity index, uniformity index, and dominance index.The research results were found 8 types of sea urchins were found consisting of 4 families, namely the Diadematidae family (Echinothrix calamaris, Diadema setosum, Diadema savignyi and Diadema palmeri), Toxopneustidae family (Tripneustes gratilla and Pseudoboletia maculata), Echinometridae family ((Echinometra mathaei) and Stomopneustidae family (Stomopneustes variolaris).The highest density of sea urchins was in Diadema setosum as many as 149 individuals from the three stations with a density value of 0.40 individuals / 375 m2 , while the lowest density for sea urchins was 1 individual / 375 m2 . The highest relative density was in the type of Diadema setosum as much as 149 individuals / 375 m2 and the lowest relative density was in the type of Diadema palmeri as many as 1 individual / 375 m2. The structure of the sea urchin community on Batu Jimbar beach, Sanur shows that from all stations, the value of diversity is moderate with a value of 1.65, the uniformity value is not evenly distributed with a value of 0.00349 and a dominance value of 0.22 it can be concluded that there are no species. which dominates at Batu Jimbar beach in Sanur.

Abstract

Transportation of fish seeds is the best way to move fish seeds from farmers to buyers. Proper transportation of live tilapia fish can ensure that the fish remain alive, healthy and fresh until their destination. The aim of this research is to determine the effect of density and size on fish seed catch in tilapia seed transport and to determine the interaction between density and size on tilapia seed catch in semi-open transport. Research location: Transportation was carried out from the seed source at the tilapia hatchery business in Patas Village, Gerokgak District, Buleleng Regency and ended at the Mina Anakan Jepun Fish Cultivator Group, Bebetin Village, Sawan District, Buleleng Regency, Patas, Gerokgak District, Buleleng Regency, Bali. This research used a Completely Randomized Design (CRD) with a factorial pattern with 2 factors consisting of Factor 1, namely fish density consisting of 3 levels, namely 50 fish/liter, 75 fish/liter, and 100 fish/liter. Factor 2 is the size of the fish which consists of 3 levels, namely 5-6 cm, 7-8 cm, 9-10 cm. Based on the results of treatment research, the density of fish numbers and fish size showed a very significant influence (P<0.01) on the survival rate of tilapia fry during semi-open transportation. The interaction between fish density and fish size showed no significant effect (P>0.05) on the survival rate of tilapia fish seedlings. A fish density of 100 fish/liter and a fish size of 5-7 cm resulted in the highest survival of tilapia fry during semi-open transportation.

Abstract

Horticultural commodities, especially ornamental plants, have high economic value in the market. It is necessary to research the introduction of appropriate technology in increasing the intensity of chrysanthemum cultivation such as the use of domestically created organic fertilizers and Trichoderma, which are formulated with local resources in chrysanthemums to improve quality and added value and utilize the potential of agricultural resources that are easy to apply following the ability of farmers and have a real impact on increasing income. The purpose of this research is to obtain a package of organic matter and Trichoderma that is suitable for the agro-climate, thus farmers will be interested in adopting the technology and developing it widely into their production system. The method used is field research in a greenhouse using a factorial randomized block design, with two factors that will be used to achieve the goal, namely the use of various types of organic fertilizers and the administration of Trichoderma doses. If the single treatment has a significant or very significant effect, then continue with the 5% BNT average value test, whereas if there is an interaction between the two factors, it is tested with Duncan't 5%. Based on the results of the study, all types of organic fertilizers, namely organic cow manure, organic pig manure, and organic goat manure combined with Trichoderma were able to suppress rust disease in chrysanthemums and increase the production and quality of chrysanthemums. Goat dung fertilizer and a dose of 5 tons-¹ ha of Trichoderma tended to produce flower stalk height, flower stalk weight, stem diameter, flower diameter, economical flower fresh weight and resulted in the lowest percentage of leaves affected by rust disease.
