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%.

Cocoa pod disease caused by the fungus Phytophthora palmivora has resulted in loss of cacao in Indonesia, especially in Bali. So far the disease control strategy is not fully understood. So there is a need to find an alternative by using endophytic fungi associated with cocoa plant. Endophytic fungi are needed to be explored in all parts of the cocoa plant such as stems, leaves and husks. The prevalence of fungal endophyte was determined by the size of its domination on the surface tissue for protection against pathogen. The exploration of the endophytic fungi benefits is aimed at finding biological agent s that could control of pathogenic P. palmivora. The results showed that 15 types of endophyte fungi have been found in the healthy leaves, stem and pod husks, with the prevalence of fungal endophyte originated from healthy leaf Mecelia sterilia (hyphae sterile) around 30%, the endophyte fungi originated from the healthy cocoa stem are Mycelia sterilia, Neurospora spp and Trichoderma spp around 25%. While the endophytic fungi originated from healthy skin fruit is Trichoderma spp. around 35%. The in vitro test results of endophytic fungi antagonistic against P. palmivora indicated that the endophyte fungi originated from the leaf namely Aspergillus spp was obtained at 80 ± 2%, A. niger 90 ± 2%, A. flavus 100%, and Trichoderma spp. 90 ± 1.5%, the endophytic fungus originated from rods namely Neurospora spp. was 95 ± 2%, and Trichoderma spp. was 90 ± 2%. While the endophytic originated from rind namely Neurospora spp . was 95 ± 1.5 % and Trichoderma spp. was 80 ± 2%. The results of in vivo test of antagonistic endophytic fungi against P. palmivora showed that all of endophytic fungi (Aspergillus sp., A. niger, A. flavus, Neurospora sp., and Trichoderma sp.) have a significant effect in suppressing the growth of mycelium P. palmivora.Keywords: Endophytic Fungus, Phytophthora Palmivora, Inhibition, Prevalence, Biological Agents

Lake Batur is the largest lake in the island of Bali. Lake Batur is widely used by the community in the aquaculture sector, namely floating net cage cultivation. The research aims to determine the influence of different stocking density on the growth rate and survival rate of the milkfish (Chanos chanos) in the 4 x 1 meters floating net cages in Lake Batur, Trunyan village. Data collection was done every two weeks during two months observation, from January 2020 – March 2020. The research used a complete random design consisting of three treatments and three replications of each treatment, which the treatment A of 15 fish/0.25m3, treatment B of 20 fish/0.25m3, and the treatment C of 25 fish/0.25m3. Measurements of fish length, fish weight, and water quality were done in situ. The results showed that the difference in stocking density had no effect on the absolute length, but those difference had an effect on the specific growth rate (SGR) and the survival rate of the fish. Treatment B resulted a maximum value of the growth rate, with an absolute length value of 0.69 ± 0.115cm/2 month and SGR 1.02 ± 0.095%/day. The fish survival rate at treatment A resulted in the highest value of 89 ± 3.46%/2 month. The value of water quality during the study were temperature of 25.9 ± 0.8oC, DO of 8.3 ± 0,1 mg/L, pH of 9.4 ± 0.2, and TDS of 995.5 ± 70.8 ppm.

In recent years environmental pollution has become a problem that needs attention because it causes negative impacts on ecosystems. The increase in cattle raising is directly proportional to livestock waste produced both from feces and excreted urine. Most people do not know how to process animal wastewater, so they dispose the livestock waste into water areas such as rivers that flow close to settlements. Water quality can be measured by several parameters, one of which is total dissolved solids (TDS). This parameter states the amount of solute both organic and inorganic in a solution. Moringa seeds have a coagulant effect due to their cationic electronic poly protein content. The purpose of this study was to determine the effect of moringa seeds on reducing TDS of livestock wastewater. The sample of this study was cattle farm wastewater taken from the cages of members of the Walung Mekar farmer group. Moringa seed powder concentrations used in this study were 50 mg/L, 100 mg/L and 150 mg/L. Observation was conducted in various time periods 0 minutes, 20 minutes, 40 minutes, 60 minutes. The TDS calculation method used gravimetric calculations (SNI 06-6989.27-2005). The results of variance indicated that Moringa oleifera powder had a very significant effect on the reduction of TDS levels in livestock wastewater. In summary, the best concentration of Moringa oleifera powder at 150 mg/L and the best deposition time at 60 minutes was able to reduce TDS levels.

A study aimed at studying the performance and production of Balinese duck carcasses that were given rations containing biosupplement-based waste of rumen content, conducted in the village of Peguyangan, Denpasar, Bali, for 3 months. Four biosupplements produced in this study were 1) BR0 = biosupplement with fermented rumen based waste without bacterial isolates, 2) BR1 = biosupplement with fermented rumen based waste with superior 1 cellulolytic bacteria inoculant (BR3.5), 3) BR2 = biosupplement with fermented rumen based waste with superior 2 cellulolytic bacterial inoculants (BR3.3), 4) BRmix = biosupplement with fermented rumen based waste with combination of superior cellulolytic bacteria 1 and 2 (BR3.5 and BR3.3), The study was carried out with Completely Randomized Sampling/CR Design with 5 treatments and 3 repetitions, in which each repetition consisted of 5 Balinese ducklings aged 2 weeks. The treatment given was to ducks given supplemented ration with BR0; BR1; BR2; BRmix, respectively for the treatment of R1; R2; R3; and R4, as well as ducks that were given basal rations without supplementation (R5). The results showed that the performance of duck that received treatment of R2 was significantly better (P<0,05) than R1, R3, R4 and R5, while the carcass butching weight and fat weight were not significantly different (P>0,05) . Based on the results obtained, it can be concluded; 1) the performance of Balinese ducks receiving ration biosupplement of R2 is better compared to R1, R3, R4 and R5; 2) Meat production/ducks carcasses to the weight of butchery, carcass production, non-carcass parts and body fats are not significantly real between all treatments.
